Answer:
Tyler and llan scored 24 points.
Explanation:
Another way to state this problem is what is 48% of 50.
"Percent" or "%" means "out of 100" or "per 100", Therefore 48% can be written as
48
100
.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number we are looking for "n".
Putting this altogether we can write this equation and solve for n
while keeping the equation balanced:
n=48,100 × 50
n = 24,001,00
n= 24

The 2 triangles formed are similar to the given triangle and to each other.
Δ ADB ~ Δ BDC
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{DB}{DC}[/tex] = [tex]\frac{AD}{BD}[/tex] , substitute values
[tex]\frac{10}{4x}[/tex] = [tex]\frac{x}{10}[/tex] ( cross- multiply )
4x² = 100 ( divide both sides by 4 )
x² = 25 ( take the square root of both sides )
x = [tex]\sqrt{25}[/tex] = 5
How can we re-write the expression below into ""friendlier"" terms? 6 ∙ 29
Answer:
A. 6 ∙ (30 - 1)
Step-by-step explanation:
How can we re-write the expression below into “friendlier” terms? 6 ∙ 29
options:
A. 6 ∙ (30 - 1)
B. 6 ∙ (16 + 13)
C. 6 ∙ (19 + 10)
D. 6 ∙ (21 + 8)
Re-writing an expression in friendlier term means expressing the term using numbers that are closest to the expression.
Checking all options,
A. 6 ∙ (30 - 1)
Option A seems closer to 6 ∙ 29 because, 30 - 1 which is very easy to evaluate gives 29
Moreover, 29 is very close to 30
Compared to other options, which have values that requires more thinking in evaluation

Laney bought 1 2/3 pounds of grapes. She also
bought bananas that were
2 1/4 times the weight of
the grapes. How much did the bananas weigh? helppppp
Answer:
The bananas weigh 3 3/4 pounds.
Answer: 3 3/4
Step-by-step explanation:
All we have to do is multiply the weight of the grapes by 2 1/4.
= 1 2/3 x 2 1/4
= 5/3 x 9/4
= 45/12
= 3 9/12
= 3 3/4
The length of a rectangle is 6 inches longer than the width. The perimeter of the rectangle is eight times the width. What is the width of the rectangle?
Answer:
The width is 3 inches.
Step-by-step explanation:
First, let's identify our variables.
L=Length
W=Width
P=Perimeter
P=2W+2L
We know that L=W+6
We can substitute L for W+6, and we can substitute P for 8W, which gives us the equation:
8W=2W+2(w+6)
If you go through all the steps to isolate the variable W, you'll end up with W=3

The focus is a fixed point inside the parabola. The line of symmetry intersects the focus and directrix. The line of symmetry and the directrix are perpendicular. The parabola intersects the directrix.
Answer:
A parabola is the set of all points equidistant from the directrix and focus.
The line of symmetry intersects the focus and directrix
The line of symmetry and the directrix are perpendicular
Step-by-step explanation:
A parabola is the set of all points in a plane that are equidistant from a fixed point (focus) and a line (directrix).
The fixed line of a parabola is known as the directrix of the parabola.
The line of symmetry is a line that passes through the focus and is perpendicular to the directrix. The line of symmetry divides the parabola.
The directrix of a parabola does not intersect touch the parabola

An engineer is designing three triangular traffic signs with a computer program. The vertices of Sign A are located at (2, 2) , (2, 12) , and (17, 7) . The vertices of Sign B are located at (4,4),(11, 19) and (18, 4) . The vertices of Sign C are located at (4, 8), (24, 1) , and (24, 15) . Put the signs in order from largest to smallest perimeter. Sign A Sign B Sign C
Answer:
sign C, sign B, sign A
Step-by-step explanation:
Given the vertices of triangular post A as (2, 2) , (2, 12) , and (17, 7). Let us find the length of side of the post using the formula for calculating distance between 2 points using the formula:
D = √(y₂-y₁)²+(x₂-x₁)²
For the coordinate (2, 2) , (2, 12)
S₁ = √(12-2)²+(2-2)²
S₁ = √(10)²+(0)²
S₁ = √100
S₁ = 10
For the coordinate (2, 2) , (17, 7)
S₂ = √(7-2)²+(17-2)²
S₂ = √(5)²+(15)²
S₂ = √25+225
S₂ = √250
S₂ = 15.8
For the coordinate (2, 12) , (17, 7)
S₃ = √(7-12)²+(17-2)²
S₃ = √(-5)²+(15)²
S₃ = √25+225
S₃ = √250
S₃ = 15.8
Perimeter of sign A = S₁+S₂+S₃
Perimeter of sign A = 10+15.8+15.8
Perimeter of sign A = 41.6
FOR SIGN B with coordinate of vertices (4,4),(11, 19) and (18, 4)
For the coordinate (4, 4) , (11, 19)
S₁ = √(19-4)²+(11-4)²
S₁ = √(15)²+(7)²
S₁ = √225+49
S₁ = 16.6
For the coordinate (4, 4) , (18, 4)
S₂ = √(4-4)²+(18-4)²
S₂ = √(0)²+(14)²
S₂ = √196
S₂ = 14
For the coordinate (11, 19) , (18, 4)
S₃ = √(4-19)²+(18-11)²
S₃ = √(-15)²+(7)²
S₃ = √225+49
S₃ = 16.6
Perimeter of sign B = S₁+S₂+S₃
Perimeter of sign B = 14+16.6+16.6
Perimeter of sign B = 47.2
FOR SIGN C with coordinate of vertices (4, 8), (24, 1) , and (24, 15)
For the coordinate (4, 8) , (24, 1)
S₁ = √(1-8)²+(24-4)²
S₁ = √(-7)²+(20)²
S₁ = √49+400
S₁ = 21.2
For the coordinate (4, 8) , (24, 15)
S₂ = √(15-8)²+(24-4)²
S₂ = √(7)²+(20)²
S₂ = √49+400
S₂ = 21.2
For the coordinate (24, 1) , (24, 15)
S₃ = √(15-1)²+(24-24)²
S₃ = √(14)²+(0)²
S₃ = √196+0
S₃ = 14
Perimeter of sign C = S₁+S₂+S₃
Perimeter of sign C = 14+21.2+21.2
Perimeter of sign C = 56.4
Arranging in order from largest to smallest perimeter, Sign C(56.4), Sign B (47.2), sign A (41.6)
which point is the image of P
Answer:
A
Step-by-step explanation:
we know that xoy is 90° on every quadrant
also the origine where p start is a little bit down from x axis so A is the right answer as it is the most logical point
D and C cant be P because are a very large angle of rotation than 105.B is smaller then 105 rotation of p so A is the right one.
Laura is planning a party for her son. She has $50 dollars remaining in her budget and wants to provide one party favor per person to at least 10 guests. She found some miniature stuffed animals for $6.00 each and some toy trucks for $4.00 each. Which system of inequalities represents this situation, where x is the number of stuffed animals and y is the number of toy trucks?
Answer:
The system of inequalities that represents this situation is:
x+y≥10
6x+4y≤50
Step-by-step explanation:
As the statement says that Laura wants to provide one party favor per person to at least 10 guests, the first inequality would indicate that the number of stuffed animals plus the number of toy trucks should be equal or greater than 10:
x+y≥10
Also, the statement indicates that miniature stuffed animals cost $6.00 each and the toy trucks cost $4.00 each and that Laura has $50. From this, you would have an inequality that indicates that 6 for the number of miniature stuffed animals and 4 for the number of toy trucks would be equal or less than 50:
6x+4y≤50
The answer is that the system of inequalities that represents this situation is:
x+y≥10
6x+4y≤50

Answer:
i dont get it
Step-by-step explanation:
Answer:
Step-by-step explanation:
Multiplicative inverse is the reciprocal of a number.
Example:
15 x ? =1
The reciprocal of 15 is 1/15 therefore,
15 x 1/15 =1
You would cross cancel the 15 integers. Leaving 1 on bothsidea

Which expressions are equivalent to 7^-2•7^6
Choose two answers
A.7^2/7^-2
B.7^6/7^-2
C.7^-12
D.(7^2)^2
===========================================
Explanation:
The expression 7^(-2)*7^6 simplifies to 7^4
We use the rule a^b*a^c = a^(b+c). In this case a = 7, b = -2, c = 6
In short, we add the exponents.
----------
In choice A, we use the rule (a^b)/(a^c) = a^(b-c) where we're now subtracting the exponents.
Here we have the exponents subtract to b-c = 2-(-2) = 2+2 = 4. This shows that (7^2)/(7^(-2)) = 7^4
This is why choice A is one equivalent expression.
----------
Choice D is the other equivalent expression since
(7^2)^2 = 7^(2*2) = 7^4
The rule used here is (a^b)^c = a^(b*c). We're multiplying exponents now.
-----------
Alternatively you can find that 7^(-2)*7^6 = 2401 through use of a calculator.
Then go through each answer choice to see which also produce a result of 2401.
