Given:
Leon had 84 paper clips.
He gave [tex]\dfrac{3}{4}[/tex] of them to Joe.
Joe gave [tex]\dfrac{2}{7}[/tex] of what he received to Justin.
To find:
How many paper clips did Justin get?
Solution:
Leon had 84 paper clips and he gave [tex]\dfrac{3}{4}[/tex] of them to Joe.
Number of paper clips Joe has = [tex]\dfrac{3}{4}\times 84[/tex]
= [tex]63[/tex]
Joe gave [tex]\dfrac{2}{7}[/tex] of what he received to Justin.
Number of paper clips Justin has = [tex]\dfrac{2}{7}\times 63[/tex]
= [tex]18[/tex]
Therefore, Justin has 18 paper clips.
Find the measure of missing angles
B is 20 degrees, c is 160 degrees.
A straight line is 180 degrees, but because there are 2 lines, they cut into each-other causing there to be 4 angles, 2 pairs of the same amount, let the known angle be angle A.
Angle A and angle B are the same, Angle A is 20 degrees meaning that angle B is 20 degrees, leaving 160 degrees to be what c equals
Angle B= 20 degrees
Angle C= 160 degrees
There are 24 cans of soda arranged in 4 rows of 6 cans each. Each can is a
cylinder with a radius of 4 cm and a height of 15 cm. These cans are to be packed
snuggly into a rectangular prism case with no extra space on the top, bottom, or
sides. Determine the volume, in cubic centimeters, of the case (rectangular prism).
Answer:
23,040 cm^3.
Step-by-step explanation:
The case will be 6 * diameter of a can in length,
= 6* 8= 48 cm.
The width will be 4 * 8 = 32 cm.
The height = height of each can
= 15 cm.
So the volume of the case = 15*32*48
= 23,040 cm^3.

A plumber charges a flat fee of $74 to visit a home and examine a clogged drain. The plumber charges an additional $28 per hour spent fixing the drain. The
total cost, C (in dollars), for fixing a drain that takes h hours is given by the following.
C = 74+28
Answer the following questions.
(a) If the plumber charged a total of $382, how many hours did she spend fixinal
Answer: A. 74+28(7)=$382
B. 28 hours.
Step-by-step explanation: or b, what you need to do is minus 74 from 382. Then divided by 28.
Answer:
11 hours
Step-by-step explanation:
h = hours
382 = 74 + 28h
subtract 74 from both sides
308 = 28h
h = 11
Check:
382 = 74 +28(11)
382 = 308 + 74
382 = 382
Which is an example of a quadratic function whose graph opens downward and has its vertex at (0, 1)?
A. y = −x^2 + 1
B. y = x^2 + x − 1
C. y = x^2 + 4x + 1
D. y = x^2 − 1
Given:
The graph of a quadratic function opens downward and has its vertex at (0, 1).
To find:
The quadratic function.
Solution:
The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where, a is a constant and (h,k) is the vertex.
If a<0, then graph opens downward and if a>0, then graph opens upward.
It is given that the quadratic function opens downward and has its vertex at (0, 1). It means a must be negative.
Putting h=0 and k=1 in (i), we get
[tex]y=a(x-0)^2+1[/tex]
[tex]y=ax^2+1[/tex]
For [tex]a=-1[/tex],
[tex]y=(-1)x^2+1[/tex]
[tex]y=x^2+1[/tex]
So, option A is correct.
In other options the leading coefficient is positive it means their graphs open upward. So, options B, C and D are incorrect.
Therefore, the correct option is A.
a) 3.x + y = 11
a)
2x-y=4
Step-by-step explanation:
3x + y = 11 ...(1)
2x - y = 4 ...(2)
From equation (1) we get,
3x + y = 11
x = 11 - y/3
Now, put the value of x = 11 - y/3 in equation (2) we get,
2x - y = 4
2(11 - y/3) - y = 4
22 - 2y/3 - y = 4
22 - 2y - 3y = 12
22 - 5y = 12
5y = 22- 12
5y = 10
y = 10/5
y = 2
Now, Put the value of y = 2 in equation (1)
3x + y = 11
3x + 2 = 11
3x = 11 - 2
3x = 9
x = 9/3
x = 3
Thus, The value of x is 3 and y is 2
FOR VERIFICATION ONLY:3x + y = 11
3(3) + 2 = 11
9 + 2 = 11
11 = 11
2x - y = 4
2(3) - 2 = 4
6 - 2 = 4
4 = 4
Hence, L.H.S = R.H.S

The measure of angle ABC by the given data is 57 degrees.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
∠ABD=70∘
Now,
To find the measure of angle ABC, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We can write an equation using this fact and the given information:
m∠ABD + m∠CBD + m∠ABC = 180 70 + (5x + 13) + (3x + 33) = 180
To solve for x, we need to simplify and isolate it by performing the inverse operations on both sides. We can do this by following these steps:
Step 1: Combine like terms on both sides of the equation.
70 + 5x + 13 + 3x + 33 = 180 8x + 116 = 180
Step 2: Subtract 116 from both sides of the equation.
8x + 116 - 116 = 180 - 116 8x = 64
Step 3: Divide both sides by 8 to get x by itself.
8x / 8 = 64 / 8 x = 8
Now that we have the value of x, we can plug it into the expression for m∠ABC and simplify:
m∠ABC = 3x + 33 m∠ABC
= 3(8) + 33 m∠ABC
= 24 + 33 m∠ABC = 57
Therefore, by algebra the answer will be 57 degrees.

Answer:
C is a right triangle
Step-by-step explanation:
To determine if the triangle is right use Pythagoras' identity
A
9.4² = 88.36
6.4² + 7.1² = 91.37
88.36 ≠ 91.37 , thus not a right triangle
B
8.4² = 70.56
5.2² + 6.3² = 66.73
70.56 ≠ 66.73 , thus not a right triangle
C
9.7² = 94.09
6.5² + 7.2² = 94.09
Thus C is a right triangle
D
8.4² = 70.56
5.1² + 7.3² = 79.3
70.56 ≠ 79.3 , thus not a right triangle
Answer:
Answer C is the correct one
Step-by-step explanation:
Remember that the Pythagorean Theorem applies only to right triangles. In Answer A, the legs of the triangle shown are 6.4 and 7.1; we apply the Pythagorean Theorem and check whether the length of the hypotenuse is indeed 9.4:
6.4² + 7.1² = 40.96 + 50.41 = 91.37.
Is √91.37 equal to 9.4? Not quite! For now, reject Answer A.
Answer B: 5.2² + 6.3² yields 66.73. Is this equal to 8.4²? No, it is not.
Reject Answer B.
Answer C: 7.2² + 6.5² = 94.09. Is this equal to 9.7²? YES. So Answer C is the correct one.

A bakery takes three types of bread, with the monthly cost being RM 6850
for 2150 loaves of bread. The cost of baking a loof of butterscotch bread
is km 2 a chocolate bread km 3 and a coconut bread Rm 4. The sale prices
of a loaf of butterscotch bread a chocolate bread and a coconut bread
are km 3 , RM 4.50 and km s. so respectively - It the bakery makes a profit
RM 2975 monthly how many loaves of each type of bread will it bake)
Answer:
The bakery will bake 600 butterscotch bread, 550 chocolate bread, and 1,000 coconut bread
Step-by-step explanation:
In order to answer the word problem question, we list the parameters as follows;
The number of bread types the bakery takes = 3 types of bread
The monthly cost of the bakery for baking the bread, C = RM 6,850
The number of bread loaves baked = 2,150
The cost of baking a loaf of butterscotch bread = Rm 2
The cost of baking a loaf of chocolate bread = Rm 3
The cost of baking a loaf of coconut bread = Rm 4
The sale price of a butterscotch bread = Rm 3
The sale price of a chocolate bread = Rm 4.50
The sale price of a coconut bread = Rm 5
The amount of monthly profit the bakery makes, P = Rm 2,975
Therefore, the total revenue of the company, R = C + P
∴ R = Rm 6,850 + Rm 2,975 = Rm 9,825
Let 'x', 'y', and 'z', represent the number of loaves of butterscotch, chocolate, and coconut bread the company bakes respectively
Then we get;
x + y + z = 2,150...(1)
2·x + 3·y + 4·z = 6,850...(2)
3·x + 4.5·y + 5·z = 9,825...(3)
Multiplying equation (1) by 2 and subtracting from equation (2) gives;
2·x + 3·y + 4·z - 2×(x + y + z) = 6,850 - 2 × 2,150 = 2,550
2·x - 2·x + 3·y - 2·y + 4·z - 2·z = 2,550
∴ y + 2·z = 2,550...(4)
Adding equation (1) to (2) and subtracting from (3) gives;
3·x - 3·x + 4.5·y - 4·y + 5·z - 5·z = 9,825 - (6,850 + 2,150) = 825
1.5·y = 825
y = 825/1.5 = 550
The number of loaves of chocolate bread baked, y = 550
From equation (4), we get;
550 + 2·z = 2,550
2·z = 2,550 - 550 = 2,000
z = 2,000/2 = 1,000
The number of loaves of coconut bread baked, z = 1,000
∴ From equation (1) x = 2,150 - (550 + 1,000) = 600
The number of loaves of butterscotch bread baked, x = 600.

Triangle LMN similar to triangle OPQ find the measure of side PQ round your answer to the nearest 10th if necessary
*see attachement for the triangles given
Answer:
PQ = 6.8
Step-by-step explanation:
Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:
LN/OQ = MN/PQ
LN = 5
OQ = 17
MN = 2
PQ = ?
Plug in the values
5/17 = 2/PQ
Cross multiply
5*PQ = 2*17
5*PQ = 34
PQ = 34/5
PQ = 6.8

Fred wants to put a carpet in this room. The carpet costs $15.00 a square yard, how much would it cost for a 3 ft by 6 feet by 9ft by 12 ft
Solution :
Cost of carpeting per square yard = $ 15.00
For 3 ft by 6 ft
1 yard = 3 feet
∴ 1 feet = [tex]$\frac{1}{3}$[/tex] yard
So,
Therefore, area of 3 ft by 6 ft is = [tex]$3 \times \frac{1}{3} \times 6 \times \frac{1}{3} $[/tex]
= 1 x 2
= 2 square yard
Therefore, cost of carpeting 2 square yard = 2 x 15
= $ 30
For 9 ft by 12 ft
1 yard = 3 feet
∴ 1 feet = [tex]$\frac{1}{3}$[/tex] yard
So,
Therefore, area of 9 ft by 12 ft is = [tex]$9 \times \frac{1}{3} \times 12 \times \frac{1}{3} $[/tex]
= 3 x 4
= 12 square yard
Therefore, cost of carpeting 2 square yard = 12 x 15
= $ 180

Cash Orcheck had a balance of $867 in his checking account on
January 1. During January, Cash wrote checks for the following
amounts: $98. $456, $29, and $381. What was his balance at the
end of January?
Answer:
Well since he wrote the amount, he’s technically giving cash away so you basically jsut add everything.
98+456+29+381= 964
867-964= -97
His final balance would be -97
Here’s the thing, a checking account acts like a debit card. Its your own cold hard cash. That means you can’t give away more then you have.
So here are the two options
1) At least one or at most 2 checks must’ve bounced
2) He got more money in his checking account
