Answer:

z = 65

Step-by-step explanation:

z + 81 + 34 = 180 (Sum of angles in a triangle is 180)

z + 115 = 180

z = 180 - 115

z = 65

Answer:

x=-6

Step-by-step explanation:

Answer:

[tex]h^{-1}[/tex] (x) = 2x - 6

Step-by-step explanation:

let y = h(x) and rearrange making x the subject

y = [tex]\frac{1}{2}[/tex] x + 3 ( multiply through by 2 to clear the fraction )

2y = x + 6 ( subtract 6 from both sides )

2y - 6 = x

Change y back into terms of x with x = [tex]h^{-1}[/tex] (x)

[tex]h^{-1}[/tex] (x) = 2x - 6

Answer:

8a + ab + 5

Step-by-step explanation:

1. a + 7a+3ab-2ab-1+6

2. combine like terms

(a + 7a) + (3ab - 2ab) + (-1+6)

8a + ab + 5

Answer:

8a + ab + 5

Step-by-step explanation:

combine like terms. like term have same variables

a and 7a  ; 3ab and (-2ab) ; (-1) and 6 are like terms

a + 7a + 3ab - 2ab - 1 + 6 = 8a + ab + 5

Answer:

25 km

Step-by-step explanation:

1 km in 4m

so

100/4 = 25

25km

Look at the explanation to understand the answer.

Step-by-step explanation:

Step 1.

Rewrite (a2) in a2 + 6 so the a is before 2

(a2 + 6) + (4a + 6) ⇒ (2a + 6) + (4a + 6)

Step 2.

We'll need to organize 2a + 6 + 4a + 6 into groups of like terms, so we can combine them easier.

They're two groups of like terms in the expression.

First group: 2a and 4a

Second group: 6 and 6

Now, rewrite it so the 6 is added by the other 6.

2a + 4a + 6 + 6

Step 3.

We'll need to combine like terms in 2a + 4a + 6 + 6 by adding all the numerical coefficients and copying the literal parts, if any. No numerical coefficient implies value of 1. Numerical 'like' terms will be added.

We already know the groups with like terms.

First group: 2a and 4a

Second group: 6 and 6

Let's solve.

2a + 4a = 6a

6 + 6 = 12

Combine 6a and 12 up and you'll get your answer.

6a + 12 is the answer.

Answer:

Answers below.

Step-by-step explanation:

Inititally as x increases, y remains the same.

Afterword, the slope = 2 for x = 3 to x = 5.

the slope = 1 for x =5 to x =9.

the greatest value of y is y = 4 when x = 5.

Answer:

[tex] {x}^{2} + 9x + 20[/tex]

Step-by-step explanation:

1) Use FOIL method: (a + b) (c + d) = ac + ad + bc + bd.

[tex] {x}^{2} + 5x + 4x + 20[/tex]

2) Collect like terms.

[tex] {x}^{2} + (5x + 4x) + 20[/tex]

3) Simplify.

[tex] {x}^{2} + 9x + 20[/tex]

Therefor, the answer is x² + 9x + 20.

Answer: The interest rate can he afford to pay on his  | loan =7.5%

Step-by-step explanation:

Given: Principal amount = 375,000

Interest amount per year =  $28,125

Interest percentage = [tex]\dfrac{\text{Interest}}{\text{Principal}}\times100\%[/tex]

[tex]=\dfrac{28125}{375000}\times100\%\\\\=7.5\%[/tex]

Hence, The interest rate can he afford to pay on his  | loan =7.5%

Answer:

ok-

first thing to do is break the shapes into regular shapes that you already know how to figure the area of. so, #1 and #2 become an upright rectangle with a square attached to the bottom. #? is a rectangle with a semicircle at each end. #5 is a rectangle with a triangle up top... etc.

then, you figure the area of each part and add them all together.

let's look at #1:

right away, I see a square sticking off the right side that is 20x20- so that part is 400sq inches

then, I see the remainder as a rectangle that is 23x22.

23x22=506sq inches

then, add the 2 parts together.

506+400= 906sq inches total.

hope that helps!

Answer:

7,850

Step-by-step explanation:

The approximate bill of impression is $7850.

A mathematical arithmetic operation is a multiplication. Moreover, it is the practice of repeatedly adding the same expression kinds.

Example: 2 + 3 means that 2 is multiplied by 3 or that 3 is multiplied by 2 times.

Given:

Your social media ad costs $2.50 per thousand impressions.

You get 3.14 million impressions.

In a million,

there are 1000 of thousand in million.

So, there are 1000 times 3.14 of thousand impressions.

The amount in the bill,

= 3.14 x 1000 x 2.5

= $7850

Therefore, the bill is $7850.

Step-by-step explanation:

It does

if you think about the difference between the first term of y and the first term of x it is 4. then you take the difference between the second term of y and the second term of x which is 7. Then take the difference between the third value of y and the third value for x which is 10. The difference between those differences is 3 which is constant!

Answer:

3, 1, - 1, - 3 and - 15

Step-by-step explanation:

To find the first 4 terms substitute n = 1, 2, 3, 4 into the rule, that is

a₁ = 5 - 2(1) = 5 - 2 = 3

a₂ = 5 - 2(2) = 5 - 4 = 1

a₃ = 5 - 2(3) = 5 - 6 = - 1

a₄ = 5 - 2(4) = 5 - 8 = - 3

The first 4 terms are 3, 1, - 1, - 3

For 10th term substitute n = 10 into the rule

a₁₀ = 5 - 2(10) = 5 - 20 = - 15

Question isn't well formatted and seems incomplete :

Rockys rock quarry has three different sized trucks. Each truck can hold three ba the shipping manger put three bags that each hold about 200 pounds. The total weight of in the truck.

Answer:

Step-by-step explanation:

Given that:

Number of trucks = 3

Number of bags each truck can hold = 3

Weight per bag = 200 pounds

Amount of in each truck :

Weight per bag * number of bags

200 * 3 = 600 pounds

Which is 600 pounds per truck

Total pounds carried by the trucks :

600 pounds * 3 = 1800 pounds

Answer:

135°, 135° and 90°

Step-by-step explanation:

It is given a triangle with a right angle (90°) and the other two angles have equal measures, so they are both (45°)

exterior angles are thus 180 - 45, 180 - 45, 180 - 90

which are 135°, 135° and 90°.
