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

y > 15/3

y > 5

The graph will have an open hole at 5 and shading to the right.

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

So

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

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

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

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

Multiplying all numbers:

A·9B·A·A·A = 9A⁴B = 9·5⁴·3 = 16875

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

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

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
