Answer:
75 questions total
Step-by-step explanation:
15 questions are multiple choice and represent 20% (or 1/5) of the total questions on the test.
If 1/5 is 15, then 5/5 would be 15 x 5 = 75 questions total.

A figure is shown. Lines m and n are cut by a transversal (line 1). 2 52 2x What is the measure of 2 y. in degrees?
Answer:
y = 38°
Step-by-step explanation:
Lines m and n are the parallel lines and 'l' is a transversal line.
Therefore, by the corresponding angles theorem,
2x = 52°
x = 26°
∠BAC = 2x° = 52° [Vertically opposite angles]
m∠ABC = 90°
In ΔABC,
m∠ABC + m∠BAC + m∠BCA = 180° [Triangle sum theorem]
90° + 52° + y° = 180°
y = 180 - 142
y = 38°

A map of New York has a scale of 1/2 inch : 5 miles. Cindy knows the
distance to her grandmother's house is 85 miles. How many inches will the
distance be on the map?
Answer:
8.5 inches
Step-by-step explanation:
1/2 in = 5 miles
? = 85 miles.
So you would do 85/5 to figure out how many times you have to multiply 5 to get to 85.
85/5= 17
So then you would multiply 17 by 1/2 to get the answer 8.5. So that would b 8.5 inches
Solve for t.
4 = 2 + 2/5 t
Answer:
T = 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4=2/5t + 2
Step 2: Flip the equation.
2/5t + 2 = 4
Step 3: Subtract 2 from both sides.
2/5t + 2 − 2 = 4 −2
2/5t = 2
Step 4: Multiply both sides by 5/2.
(5/2) *(2/5t)= (5/2) *(2)
Answer:
t=5
Answer:
t=5
Step-by-step explanation:
4=2+2/5 t
Subtract 2 from both sides
2=2/5 t
Multiply 2/5 by its reciprocal on both sides so multiply by 5/2
(5/2) times 2 is 5
so t is 5

A parallelograms base is twice its height. If the parallelogram has an area of 32 square feet, what are the lengths og the base and height.
Answer:
4 ft. = height
8 ft. = base
Step-by-step explanation:
Let h = length of the height
2h = length of the base
A = bh
32 = 2h(h) = [tex]2h^{2}[/tex]
[tex]h^{2}[/tex] = 16
h = 4 ft. = height
8 ft. = base

The expression has a value greater than 253 is 253 x 9/2 and 253 x 4/1.
What is Expression?In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.
Given:
We have to find the number whose value greater than 253.
1. 253 x 3/4
= 253 x 0.75
= 189.75
2. 253 x 5/5
= 253
3. 253 x 9/2
= 253 x 4.5
= 1138.5
4. 253 x 6/7
= 216.85
5. 253 x 4 /1
= 1012
Thus, the Expression having value greater than 253 is 253 x 9/2 and 253 x 4/1.

You found Genie hidden in a dungeon. Genie is offering two different options for you as a reward for finding him. There are two options shown for you to choose.
Which option would you choose? Explain your reasoning using the key features of exponential functions.
Answer:
The first option is
A(x) = 10000(1.05)ˣThe second option is:
B(0) = 1000B(1) = 1100The ratio is 1.1 and the zero term is 1000The equation for this option is:
B(x) = 1000(1.1)ˣNow, which option is better?
It depends on the number of x. It is assumed the genie is offering money or similar reward.
For the values of x below 50 option A is better and option B is much better for x > 50.
See the graph in the attachment, where green line represents the option A and red line is option B.
