Q varies as e if q is 24 when e is 3 find q when e is 7
Answer:
q = 56
Step-by-step explanation:
Given that q varies as e, then the equation relating them is
q = ke ← k is the constant of variation
To find k use the condition q = 24 when e = 3 , then
24 = 3k ( divide both sides by 3 )
8 = k
q = 8e ← equation of variation
When e = 7 , then
q = 8 × 7 = 56

Please do number 16 for me. (With work)
Answer:
m<5 = 75°
Step-by-step explanation:
16. Given:
m<1 = 75°; m<3 = 40°
Required:
m<5
Solution:
Since lines A and B are parallel, and m<1 corresponds to m<5, therefore,
m<1 = m<5 (corresponding angles are congruent)
m<1 = m<5 = 75°
m<5 = 75°

Sue decided to interview two of the six city council members. She labeled their names from 1 to 6, then rolled a six-sided die until she got two different numbers telling her which to interview. Is this sample of the city council members likely to be representative? yes no
Answer:
Step-by-step explanation:
This question seems a lot harder than it actually is since in the end of the day, she ends up interviewing 2 council members.
2 is 1/3 of 6 since 2/6 = 1/3
So there is a 33.3333... % or 1/3 chance that one of the 2 members she interviewed got chosen as representative.

The ratio of boys to girls in a group is 3:1. If there are 52 more boys than girls, work out how
many people there are in total.
Answer:
104
Step-by-step explanation:
The ratio of boys : girls = 3 : 1 = 3x : x ( x is a multiplier )
There are 52 more boys than girls , so
3x = x + 52 ( subtract x from both sides )
2x = 52 ( divide both sides by 2 )
x = 26, then
3x = 3 × 26 = 78 ← number of boys
Total number = 78 + 26 = 104
What is the equation, in point-slope form, of the line passing through the point (-5, 9) with a slope of -1/4?
Answer:
y = -1/4x + 7.75
Step-by-step explanation:
plug in the point
y = mx + b
9 = -1/4(-5) + b
9 = 5/4 + b
b = 31/4 (7.75)
plug b back into the equation

Each TTF site bought a new rope bridge for 4,500. TTF will make monthly payments of $350 until the bill is paid. Write an equation for the unpaid balance B after m monthly payments
Answer: 4500 - 350m
Step-by-step explanation:
From the question, we are informed that each TTF site bought a new rope bridge for 4,500 and that TTF will make monthly payments of $350 until the bill is paid.
The equation for the unpaid balance B after m monthly payments will be:
= 4500 - 350m
where me = number of months
For example, if the number of months used is 4 months, the unique balance will be:
= 4500 - 350m
= 4500 - 350(4)
= 4500 - 1200
= 3300
What is the value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 +0.5 x)?
3
이를
02
0 13
Answer:
Step-by-step explanation:
15x - 10 = 10 + 6 + 2x
15x - 10 = 16 + 2x
Bringing like terms on one side
15x - 2x = 16 + 10
13x = 26
x = 26/13
x = 2
The value of x in the equation is 2.
Option C is the correct answer.
What is an equation?An equation is a mathematical statement that shows that two expressions are equal.
It consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. Equations are used to solve problems and find unknown values.
We have,
We are given the equation 2.5(6x - 4) = 10 + 4(1.5 + 0.5x) and we need to find the value of x that satisfies this equation.
First, we can simplify both sides of the equation by using the distributive property of multiplication.
This gives us:
15x - 10 = 10 + 6 + 2x
Next, we can combine like terms on both sides of the equation. Specifically, we can combine the constants on the right-hand side:
15x - 10 = 16 + 2x
Now, we want to isolate the term with x on one side of the equation.
We can do this by subtracting 2x from both sides of the equation:
13x - 10 = 16
Finally, we can solve for x by adding 10 to both sides of the equation and then dividing both sides by 13:
13x = 26
x = 2
Therefore,
The value of x in the equation is 2.
