Answer: Option A: The entire expression is a sum.
Option C: The term is a quotient are true statements.
Step-by-step explanation:
Determine which statements are true:
Option A: The entire expression is a sum.
All of the given terms are additions. Thus, it is true not false.
Option B: The coefficient of s is 3.
False ,s has no denominator 3 in it. In the equation for s, the coefficient is .
Option C: The term is a quotient.
The dividend is 7, the divisor is r, and the quotient is 7. So, It's true.
Option D: The term has a variable.
False, variables are not present in the term.
In analysis, Option A: The entire expression is a sum, and Option C: The term is a quotient are true statements.
Christopher bought 3 toy trucks that costs $14.25 each. He used a coupon for 15% off of the total purchase. Rounded to the nearest cent, what was the final cost of Christopher's toy trucks?
Answer: $36.3
Step-by-step explanation:
Since Christopher bought 3 toy trucks that costs $14.25 each. Then, the cost of the three toys will be:
= 3 × $14.25
= $42.75
Then, if he used a coupon for 15% off of the total purchase, then the final purchase will be:
= $42.75 - (15% × $42.75)
= $42.75 - (0.15 × $42.75)
= $42.75 - $6.4125
= $36.3375
= $36.3

Chin was shown the graph of a line that contained point (1, 7). He wrote f(x) = 4x + 3 to correctly represent the line. Which of these equations could represent the same line?
y – 7 = 3(x – 1)
y – 1 = 3(x – 7)
y – 7 = 4(x – 1)
y – 1 = 4(x – 7)
The equation that represents the same line containing point (1, 7) is as follows:
y - 7 = 4(x - 1)
Slope intercept form equation:y - y₁ = m(x - x₁)where
m = slope
The graph of the line contains (1, 7) .He represent the line correctly as f(x) = 4x + 3.
The equation that represent the same line is as follows:
Using the model:

Answer:
a₄ = 256
Step-by-step explanation:
Using the given definition , then
a₂ = a₁² = 2² = 4
a₃ = a₂² = 4² = 16
a₄ = a₃² = 16² = 256
Answer:
256
Step-by-step explanation:
a₁ = 2
a₂ = (a₁)² = 2 ² = 4
a₃ = (a₂)² = 4² = 16
a₄ = (a₃)² = 16² = 256
A pool has two inlet pumps A and B. If pump A alone is open, it takes 12 hours to fill the pool with water. If pump B alone is open, it takes 18 hours to fill the pool with water. If the pool needs to be filled in 10 hours, what is the least amount of time (in hours) both pumps need to be open?
Answer:
The least amount of time (in hours) both pumps need to be open is 3 hours.
Step-by-step explanation:
According to the Question,
Given That, A pool has two inlet pumps A and B. If pump A alone is open, it takes 12 hours to fill the pool with water. If pump B alone is open, it takes 18 hours to fill the pool with water.Let the Capacity of the Pool is 36Litre.
Thus, If pump A alone is open, it takes 12 hours to fill the pool with water. thus the Efficiency of Pipe A is 3 ltr/hour.And, If pump B alone is open, it takes 18 hours to fill the pool with water. thus the Efficiency of Pipe B is 2 ltr/hour.If the pool needs to be filled in 10 hours the least amount of time (in hours) both pumps need to be open is 3 hours.
Note:- if 3 hour both pipe open so 3 x (5) = 15 ltr Pool is Filled.
Now For Remaining 7 hour Pipe A with Efficiency 3 ltr/hour is open alone to fill the pool Remaining 7 x 3 = 21 ltr . Total 21+15 = 36ltr .
Justin needs to earn a score of more than 80 on his next math test to earn a B for the semester. Which inequality shows the grades that will allow Justin to earn a B? Please answer!
Answer:
b
Step-by-step explanation:
Justin's score has to be greater than 80. the appropriate inequality sign is >
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
On the number line, since the score has to be greater than 80, the line would start from 80 and end on 95
> or < is represented by unfilled circle
≤ or ≥ is represented by filled circle

Step 1: 9ft -6ft= 3ft
Step 2: 7ft -4ft= 3ft
Answer: 3ft + 3ft + 7ft + 9ft + 4ft + 6ft= 32 ft
Answer:
54 ft²
Step-by-step explanation:
The figure is composed of 2 rectangles
area of lower one = 4 × (9 - 6) = 4 × 3 = 12 ft²
area of upper one = (4 + 3) × 6 = 7 × 6 = 42 ft²
Then
area of figure = 12 + 42 = 54 ft²

fine measure of each angle indicated
Find the value of X:
Answer:
Step-by-step explanation:
If AS is an angle bisector, then angle XAS is congruent to angle PAS; mathematically, that looks like this:
3x + 15 = 2x + 30 and x = 15.
3(15) + 15 = angle XAP, which is 120.
Because angle XAS is congruent to angle PAS, then the sides across from those congruent angles also should be congruent. Let's check it, just to make sure:
XS = PS --> 2(15) + 9 = 39 and 4(15) - 21 = 39. So that checks out. Because AS is congruent to itself by the reflexive property, then what this means is that triangle XAS is congruent to triangle PAS, making angle x and P the same measure. Looking at the whole big triangle, triangle XAP, if angle XAP measures 120, then angle X = angle P = (180 - 120) / 2, so angle X = 30.

37 for drama club
27 for yearbook club
Hello,
Students in a drama club + in a yearbook club : 64
Students in a drama club : 10 more students than the yearbook club
Let x be the number of students in a drama club and y the number of students in the yearbook club.
We have :
x = y + 10 ⇔ x = 27 + 10 = 37
x + y = 64 ⇔ y + 10 + y = 64 ⇔ 2y = 54 ⇔ y = 27
There are 37 students in the drama club and 27 students in the yearbook club.

PLEASE HELP MEEEEEEEEEEEEE
Answer: 20 ft
Step-by-step explanation:
The mirror is set away from the flagpole on the same scale set away from her.
The distance she stand's away from the mirror is 1/4 of the length of the distance between the mirror and the flag pole because she's 1/4 of the flagpole's size.
This means her size x4 is the size for the flag pole. This checks out because 12x4=48
So to find the height we must do 5x4
5x4=20

Answer:
3 3/7 hours
Step-by-step explanation:
The formula is
1/a+1/b = 1/c
where a and b are the times working alone and c is the time working together
1/8 + 1/6 = 1/c
Multiply each side by 24c to clear the fractions
24c(1/8 + 1/6) = 1/c *24c
3c + 4c = 24
7c = 24
Divide by 7
7c/7 = 24/7
c = 3 3/7 hours

Answer:
The "x" intercept is a point with coordinates [tex](-\frac{4}{9},0)[/tex].
Step-by-step explanation:
In order to solve this, we need to know that the "x" intercept is the point where the line touches the x-axis, therefore this point will have the "y" coordinate equal to 0. Knowing this, we can substitute "y" with 0 and find the "x" coordinate of the "x" intercept. So we do...
[tex]y = -\frac{9}{2} x - 2\\\\0 = -\frac{9}{2} x - 2\\\\\frac{9}{2} x = - 2\\\\\\x = - \frac{4}{9}[/tex]
Therefore, the "x" intercept is a point with coordinates [tex](-\frac{4}{9},0)[/tex].

Answer:
12 cm and 17 cm
Step-by-step explanation:
In all triangles, the sum of any two sides must be greater than the third side. To test this, choose the two shortest sides of the triangle and see if they add to be larger than the third side. If this holds true, then the triangle is possible because all other sides you can choose will also hold true.
Trying each of the answer choices, we have:
[tex]\checkmark 10+12> 17,\\\times 5+10 \ngtr 15,\\\times 1+8 \ngtr 10,\\\times 3+7 \ngtr 10[/tex]
Therefore, the answer is 12 cm and 17 cm.

Answer:
The input for the method is a continuous function f, an interval [a, b], and the function values f(a) and f(b). The function values are of opposite sign (there is at least one zero crossing within the interval). Each iteration performs these steps: Calculate c, the midpoint of the interval, c = a + b2.

Find the measure of angle A using the image below:
Answer:
A = 125º
Step-by-step explanation:
Missing angle is the supplement of 157.5
180 - 157.5 = 22.5
----------------------------
Sum of angles in triangle is 180
22.5 + (-10x) + (-x + 20) = 180
Combine like terms
-11x + 42.5 = 180
Subtract 42.5 from both sides
-11x = 137.5
Divide both sides by -11
x = -12.5
---------------------------
A = -10(-12.5)
A = 125º
if y varies directly with an x and y=12 when x=-1, find y if x=2
Answer:
y = -24
Step-by-step explanation:
Direct variation is
y = kx where k is a constant
12 = k*(-1)
12/(-1) =k
-12 = k
The equation is y = -12x
Let x = 2
y = -12(2)
y = -24
