Abe had 156.43$ in his bank account at the beginning of the month. He made the two withdrawals shown in his check register. How much money does he have left in his bank account? He must have at least 100$ in his account by the end of the month or he will be charged a fee. How much money does he need to deposit to avid being charged a fee?
Answer:
$92.05$7.95Step-by-step explanation:
1. Abe had $156.43 in his account and then withdrew $24.97 and $39.41. The amount left is;
= 156.43 - 24.97 - 39.41
= $92.05
2. He needs to have at least a $100 to avoid a fee so the minimum he needs to deposit is;
= 100 - 92.05
= $7.95

the perimeter of a rectangular window is 280cm. if the length of the window is 83cm, what is the width
Answer:
the width would be 57cm
Step-by-step explanation:
to find the perimeter you have to add up all of the sides so for this one you would multiply 83 by 2 which would give you 166cm and then subtract it by 280cm which would give you 114cm and then you divide 114 by 2 which would give you 57

Mary has $120 to spend on a tour of a
castle with her friends. The cost is $15 for a
tour guide and then $12 per person. Which
equation best represents how many friends
she can invite?
A. 15x + 12 > 120
B. 15x + 12 < 120
C. 12x + 15 > 120
D. 12x + 15 < 120
Answer:
12x+15>120, choice C
Step-by-step explanation:
$12/person
$15/guide
X=12
It cannot be B or D because she only has 120 to spend. It is not possible to spend more than that. It cannot B either because X=12, the number f friends she can invite which is our unknown variable. The answer has to be C. It makes the most sense.
Which of the following equations is the perpendicular bisector of the line AB given:
A(3,1) & B(-3,6)
O y = 6/5x + 4
O y = 6/5x + 9/2
O y = 6/5x + 7/2
O y = -5/6x + 7/2
Answer:
C. y = ⁶/5x + ⁷/2
Step-by-step explanation:
First, find the slope of line AB that goes through A(3, 1) and B(-3, 6):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{6 - 1}{-3 - 3} = \frac{5}{-6} [/tex].
Slope of line AB = -⅚.
The slope of the line that is a perpendicular bisector of line AB will be a negative reciprocal of the slope of line AB.
Thus:
Negative reciprocal of -⅚ = ⁶/5. (Reciprocal of ⅚, also the sign will change from positive to negative).
Next is to find the y-intercept, b, of the line.
To do this, you need to find the midpoint where the two lines intersect:
Therefore,
Midpoint (M) of AB, for A(3, 1) and B(-3, 6) is given as:
[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
Let [tex] A(3, 1) = (x_1, y_1) [/tex]
[tex] B(-3, 6) = (x_2, y_2) [/tex]
Thus:
[tex] M(\frac{3 +(-3)}{2}, \frac{1 + 6}{2}) [/tex]
[tex] M(\frac{0}{2}, \frac{7}{2}) [/tex]
[tex] M(0, \frac{7}{2}) [/tex]
Substitute x = 0, y = ⁷/2, and m = ⁶/5 into y = mx + b and find the value of b.
⁷/2 = ⁶/5(0) + b
⁷/2 = b
b = ⁷/2
The slope (m) and the y-intercept, b, of the line we are looking for are ⁶/5 and ⁷/2, respectively.
Therefore, substitute m = ⁶/5 and b = ⁷/2 into y = mx + b.
y = ⁶/5x + ⁷/2
The equation that is the perpendicular bisector of the line AB is y = ⁶/5x + ⁷/2.

Bob runs 4 laps around a track in 10 minutes. A) How many minutes per lap is that? B) How many laps per minute is that? C) If Bob runs 17 laps at the same rate, how long does it take him?
Answer:
Step-by-step explanation:
Firstly, let us solve for Bobs speed
speed= distance/time
given
distance= 4 laps
time= 10 min
speed= 4/10
speed=0.4laps/min
this is the rate at which Bob is running
A) How many minutes per lap is that?
this is given as
=time/distance
=10/4
=2.5 min per lap
B) How many laps per minute is that?
this is given as
=distance/time
=4/10
=0.4lad per min
C) If Bob runs 17 laps at the same rate, how long does it take him?
given that the speed is 0.4 laps per min
and a distance of 17 laps, we want to find time
speed=distance/time
0.4=17/time
time=17/0.4
time=42.5min

Mrs. Garza went to dinner at ChaChi's with her family. The food bill was
$58.00. Because the Garza's won the lottery, Mr. Garza tipped the waiter 30%
of the food bill. How much money did the Garza's pay in total, including the
tip?
Answer:
$75.40
Step-by-step explanation:
first you need to find what 30% of 58 is. to find that you would multiply the decimal form of the percentage (so 30% would become 0.3) by 58. this gets you 17.4. then you add that to the original price (58) to get the answer (75.4). then of course you change the format so that it can fit the whole dollar and cent thing so you get $75.40.

Christina's grade for her history class will be the average of
her midterm exam, final exam, and final paper. She received a
91 on her midterm and an 86 on her paper. What grade must
she get on her final exam to receive a grade of 90 for the
class? Explain using R.A.C.E.
The average is calculated by the sum of the total test scores divided by the total number of tests. This can represented in the equation:
91 + 86 + x /3 = 90
177 + x /3 = 90 ⇒ Multiply both sides by 3 to get rid of the /3
177 + x /3 x 3 = 90 (3)
177 + x =
177 - 177 + x = 270 - 177 ⇒ Subtract 177 from both sides to isolate x
x =93
Therefore, they must get 93% to end with a 90% final mark
The population of the US is about 300 million people there are approximately 1.2×10 to the 10th power US dollars in existence if that money is given to the population equally what amount does each person receive
Answer:
206.39121408
Step-by-step explanation:
So you do, (1.2*10)^10 which equals to 61917364224. divide that number by 300million. and that answer is 206.39121408 or in money, you could say, 206 dollars and 39 cents
The population of the United States is approximately 300 million people, and there are approximately 1.2 × 10 to the tenth power US dollars in existence; if that money is distributed evenly, each person receives $206.39121408.
What is meant by equation?In its most basic form, an equation is a mathematical statement that shows that two mathematical expressions are equal. For example, 3x + 5 = 14 is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.In mathematics, an equation is a relationship of equality between two expressions written on both sides of the equal to sign. 3y = 16 is an example of an equation.A mathematical statement made up of two expressions joined by an equal sign is known as an equation.3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.Given that,
[tex](1.2\times10) ^{10}[/tex] which equals 61917364224.
divide 61917364224 by 300million
∴ 61917364224 / 300
= 206.39121408
Therefore, 206.39121408 is an abbreviation for 206 dollars and 39 cents.

Azarel spent half of his weekly allowance on comic books. To earn more
money his parents let him clean the windows in the house for $9. What is
hsi weekly allowance if he ended up with $12? *
Answer:
His weekly allowance is $6.
Step-by-step explanation:
You can get the answer by using algebraic expressions.
Let 2x be Azarel's weekly allowance.
Let [tex]\frac{1}{2}[/tex](2x) be the amount after Azarel spends his allowance on comic books.
The equation will be: 12=2x+9-[tex]\frac{1}{2}[/tex](2x)
Let's solve for x:
Step 1: 12=2x+9-x
Step 2: 12=x-9
Step 3: x=12-9
Step 4: x=3
Step 5: Replace 2x with 2(3) = 6
The answer is $6. This is the allowance of Azarel every week. He spends $3 for comic books weekly, which is half of $6.

Answer: 225 units
Regular pentagons have 5 sides of equal length and 5 angles of equal measure. so if you have one side you can solve the rest. We have y so 5 times y equals 5 times 9=45 units per side. Multiply by the number of sides (5) and you get 225 units.
Find the equation of line passing through the points A(-1,3) and B(0,2). Hence show that the points A,B and C (1,-1) are collinear.
A line passes through A( - 1 , 3) & B(0 , 2).
Prove:A , B , C(1 , 1) are collinear.
Proof:We know that,
Slope of a line passing through the co - ordinates (x₁, y₁) and (x₂ , y₂) is :
m = (y₂ - y₁)/(x₂ - x₁)
Let,
x₁ = - 1 x₂ = 0 y₁ = 3 y₂ = 2Hence,
→ m = (2 - 3)/( 0 - ( - 1))
→ m = - 1/1
→ m = - 1
Now,
Equation of a line ⟹ y - y₁ = m (x - x₁)
Putting the values we get,
→ y - 3 = - 1(x - ( - 1))
→ y - 3 = - x - 1
→ y + x = - 1 + 3
→ x + y = 2
Hence, the equation of the line is x + y = 2.
Now,
we have to prove that,
A , B , C are collinear.
If three points are collinear then the area of the triangle formed by them will be zero. Three points are collinear if the slope of line passing through the line segment are equal.i.e.,
Slope of AB should be equal to Slope of BC.
We have;
Slope of AB = - 1.
→ - 1 = ( 1 - 2)/(1 - 0)
→ - 1 = - 1/1
→ - 1 = - 1
Hence, A , B , C are collinear points.
I hope it will help you.
