Answer:

Step-by-step explanation:

We are given the expression:

1/3z+10

We also are given z=135. Since z is equal to 135, we can substitute 135 in for z.

1/3(135)+10

Now, solve according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

Multiply 135 by 1/3, or divide 135 by 3.

45+10

Add 45 and 10

Mr. Hammond is the volunteer coordinator for a company that puts on running races. Last year, the company organized 7 short race

worty [1.4K]

Answer:

28 short race volunteers

76 long race volunteers

Step-by-step explanation:

Let :

Short races = a

Long races = b

LAST YEAR:

7a + 8b = 804 - - - - (1)

THIS YEAR:

11a + 5b = 688 - - - (2)

Multiply (1) by 5 and (2) by 8

35a + 40b = 4020

88a + 40b = 5504

Subtract

-53a = - 1484

a = 1484 / 53

a = 28

Put a = 28 in equation (1)

7(28) + 8b = 804

196 + 8b = 804

8b = 804 - 196

8b = 608

b = 76

Find the value of x. Round your answer to the nearest tenth. 10 19° x

kvasek [131]

Answer:

x ≈ 9.5

Step-by-step explanation:

using the cosine ratio in the right triangle

cos19° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{10}$ ( multiply both sides by 10 )

10 × cos19° = x , then

x ≈ 9.5 ( to the nearest tenth )
