Lisa spends part of her year as a member of the gym. She then finds a better deal at another gym, so she cancels her membership with the first gym and spends the rest of the year with the second gym. (12 months total at these gyms.) The membership to the first gym costs $75 per month, while the membership for the second gym cost $50 per month. She ends up spending a total of $775 over the course of the year.

Answers

Answer:

Number of month in first gym = 7

Number of month in second gym = 5

Step-by-step explanation:

Given:

First gym member ship cost = $75 per month

Second gym member ship cost = $50 per month

Total spending = $775

Computation:

Number of month in first gym = a

Number of month in second gym = b

a + b = 12....eq1

75a + 50b = 775 ....eq2

From eq 1 and 2

a = 7 month

b = 5 month

Number of month in first gym = 7

Number of month in second gym = 5

A car journey has two stages.
Stage 1: The car travels 110 miles in two hours
Stage 2: The car travels 44 miles at the same average speed as stage 1
Work out the time for stage 2
Give your answer in minutes.

Answers

Answer:

48 minutes

Step-by-step explanation:

2h = 110 miles

1h = 110 ÷ 2

= 55 miles

Therefore, the speed of the entire journey is 55 miles per hour.

1h = 60 minutes

55 miles = 1h

55 miles = 60 minutes

44 miles = [tex]\frac{44}{55}[/tex] × 60 minutes

= 48 minutes

What is the equation of the line that passes through the point (4, -4) and has a
slope of –3/4?

Answers

Answer:

y=-3/4x-1

Step-by-step explanation:

y=mx+b; y is the y coordinate; m is the slope; x is the x coordinate; you have to find b. So you replace all the numbers out which is given to you;

-4=-3/4(4)+b (you multiply -3/4 by 4 and get -3)

-4=-3+b (you add 3 to both sides and get -1)

-1=b (you now found b so plug it into the equation)

y=-3/4x-1

Five positive whole numbers add up to 47
One of the numbers is a multiple of 9
The other four numbers are equal.
Work out the result when the five numbers are multiplied.

Answers

Greetings from Brasil...

According to the statement

A + B + C + D + E = 47

making B the multiple of 9

A + 9B + C + D + E = 47

as the other 4 numbers are the same, let's call it A

A + 9B + A + A + A = 47

4A + 9B = 47 assigning values to B, we have

B = 1 ⇒ A ∉ ℤ

B = 2 ⇒ A ∉ ℤ

B = 3 ⇒ A = 5

B = 4 ⇒ A ∉ ℤ

B = 5 ⇒ A ∉ ℤ

B = 6 → from now on, A will be negative

Then

A = 5 and B = 3

∠FED

D.
∠ACB

Answers

The option D is correct. i.e., ∠ACB

In the given question is that

Which angle is congruent to ∠DFE

Answer is ∠DFE ~ ∠ACB

Explanation: By using the illustration shows two right angled triangle ABC and triangle DEF :

Now, If in triangles ABC and triangle DEF

Angle C = Angle F (Right angle)

CB = FE (leg)

AB = DE (hypotenuse)

then, triangle ABC is congruent to triangle DEF.

By SAS rule

Whole triangle ABC is congruent to triangle DEF. Then, we can say that

∠DFE ~ ∠ACB

Hence, The option D is correct. i.e., ∠ACB

0.125 < π < 9/50 (fraction)

Answers

The solution to the inequality expression given as 0.125 < π < 9/50 is false

What are inequality expressions?

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

How to determine the solution to the inequality expression?

The inequality expression is given as

0.125 < π < 9/50

Express 0.125 as a fraction

So, we have the following inequality expression

1/8 < π < 9/50

As a general rule, we have

π = 22/7

So, the inequality expression becomes

1/8 < 22/7 < 9/50

Evaluate the quotients

So, the inequality expression becomes

0.125 < 3.14 < 0.18

The number 3.14 is not between 0.125 and 0.18

This means that the inequality expression 0.125 < 3.14 < 0.18 is false

Hence, the solution to the inequality is false
