Answers

Answer: 31.18

Step-by-step explanation:

The problem is focused on mainly the right triangle made up of points M, Q, and R.  This problem can be solved with the base formula, b = a · tan(β) where a = the length of line MR, β = m∠MQR, and b is the unknown length of RQ.  

Given:

RQ = 18 · tan(60°)

Point M is the midpoint of line PM and line MR.  Since MP is equal to 18, MR has to be 18 as well.  This means that the value of a is 18.

The vertex of ∠MQR is Q, which is 60°.

Step 1: Find the tangent of 60°

The tangent of 60° is √3

Step 2: Solve

RQ = 18 · √3

18 · √3 = 31.18

RQ is equal to 31.18

2(6x+5)=58
(solve for x)

Answers

x=4

explanation:
2(6x+5)=58
you distribute the 2 to the 6x and the 5 making the problem:
12x+10=58
you would then subtract 10 from both sides of the equation then making the problem:
12x=48
since we are trying to get x alone we would then divide each side of the equation by 12 leaving you with
x=4

Alex was biking along a 48 mile trail. First half of the time he was biking twice as fast as the second half of the time. If he spent 4 hours on the road, how fast was he biking at first?

Answers

Answer:

The speed in the first part is 16 mph.

Step by step explanation:

The total distance is 48 miles. The total time is 4 hours.

In the second part of the trip, he was traveling at speed s for distance d for 2 hours.

In the first part of the trip he was traveling

at twice the speed, or 2s, for distance 48 - d, for 2 hours.

speed = distance/time

distance = speed * time

First part of trip:

48 - d = 2s * 2

d + 4s = 48 Equation 1

Second part of the trip:

d = s * 2

d = 2s =

Equation 2

Equations 1 and 2 form a system of equations in two unknowns, d and s.

d + 4s = 48

d = 2s

Substitute 2s for d in equation 1.

2s + 4s = 48

6s = 48 =

s=8

The speed in the second part is 8 mph.

The speed in the first part is 2s = 2(8) =

16.

The speed in the first part is 16 mph.

Check:

d = 2s = 2(8) = 16

48 - d = 48 - 16 = 32

The second part is 16 miles. The first part is 32 miles.

16 miles at 8 mph takes 2 hours.

32 miles at 16 mph takes 2 hours.

2 hours + 2 hours = 4 hours.

Our answer is correct.

Answer: The speed in the first part is 16 mph.

Last year, Jackson made 24 one-cup servings of chili for a school party. This year, he will make ten times the amount of chili that he made last year. If there are 4 cups in 1 quart and 4 quarts in one gallon, how many gallons of chili will Jackson make this year?

Answers

Answer: 15

Step-by-step explanation:

You have to multiply what Jackson made last year (24 cups) times 10 which equals 240. after that you do 240 divided by 4, which equals 60, and 60 divided by 4 again, which gives us the answer (15) (hope you could understand that) Also sorry for not answering in time!

18 vocabulary words learned in 2 hours; 27 vocabulary words learned in 3 hours

Answers

Answer: They are equivalent

Step-by-step explanation:

Here is the complete question:

18 vocabulary words learbed in 2 hours 27 vocabulary words learned in 3 hours Are they equivalent? Why

From the question, we are informed that 18 vocabulary words are learned in 2 hours. The number of words learned per hour will be:

= 18/2

= 9 words per hour.

27 vocabulary words learned in 3 hours. The number of words learned per hour will be:

= 27/3

= 9 words per hour.

Since they both have identical number of words learned per hour, it means that they're equivalent.

if f(x)= x^2 and g(x) = 4f (x)-1 then which of the following is the value of g (-3)

view image below to see answer choices

Answers

Answer:

27

Step-by-step explanation:

Given

f(x)= x^2-2 and g(x) = 4f (x)-1

g(x) = 4(x^2-2) - 1

g(x) = 4x²-8-1

g(x) = 4x²-9

Get g(-3):

g(-3) = 4(-3)²-9

g(-3 = 4(9) - 9

g(-3) = 36-9

g(-3) = 27

step-by-step explanation: If there are 65 students and 10 liked math but not english you subtract 10 from 65, you get 55. You continue to the next one, 55-20= 35, now there are 35 students but 5 of those students don't like either, so 35-5=30, meaning there are 30 students that like both english and math.
