Answer:

d = [tex]\frac{7y+5}{3}[/tex]

Step by step explanation:

3d = 7y+5

Divide both sides by 3

[tex]\frac{3d}{3}[/tex]= [tex]\frac{7y}{3}[/tex]+ [tex]\frac{5}{3}[/tex]

Simplify

[tex]\frac{7y+5}{3}[/tex]

Answer:

B that's the answer for that

Answer: 18,720

Step-by-step explanation:

Let's take this equation

78,000(n)

n will equal 0.24, since we are trying to find 24% of 78,000

78,000(0.24)

18,720

Answer:

18720

Step-by-step explanation:

24/100 × 78,000

=18720

Step-by-step explanation:

Yes sure.

a. New value of painting=60/100×$550=$330

Answer:

25 students

Step-by-step explanation:

Let x = no. of students in the class

.6x = no. of students that use TT

.2(.6x) = no. of students that post videos

.2(.6)x = 3

.12x = 3

x = 25 students

Answer:

18

Step-by-step explanation:

5 kids times 3 pieces each = 15 and then add the 3 that the dad got.

Answer:

18

Step-by-step explanation:

let 'x' = pieces of candy at start

(x-3)/5 = 3

cross-multiply:

x - 3 = 15

x = 18

Answer:

=468 m^2

Step-by-step explanation:

Surface area of a prism is

SA = 2 (lw + wh + hl)  where l is length, w is width and h is height

SA = 2 ( 12*6 + 6*9 + 9*12)

      = 2 ( 72+54+108)

      = 2(234)

       =468 m^2

Answer:

B

Step-by-step explanation:

There is a 1/4 probability of getting an A out of a bag with letter MATH

For B) There are two A's our of 8 letters is ADMIRALS.

2/8 is the same as 1/4

The answer is B

A) is wrong because that 1/6

C) is wrong because that's 1/8

D) is wrong because that's 2/9

Answer:

B

Step-by-step explanation:

Probability of finding A in a word =  number of A / number of letters in that word

Probability of finding A in MATH = 1/4

A. Probability of finding A in BECAME = 1/6

B. Probability of finding A in ADMIRALS = 2/8 = 1/4

C. Probability of finding A in USERNAME  = 1/8

D. Probability of finding A in AFTERMATH = 2/9

So we have a match with option B

Answer:

165

Step-by-step explanation:

1. you have to do 10 x 8 bc she makes 10 dollars a week, and it says how much will she make in 8 weeks so you do 10 x 8. 10 x 8 = 80 , so you take the 85 dollars she has then you take the 80 and add them together and you get 165.

Answer:

Answer:

40 is your answer:)

Step-by-step explanation:

4x3= 12

12/2=6

6x4=24

4x4=16

24+16= 40

Answer:

x=12

Step-by-step explanation:

Complementary angles add up to 90 degrees. 90-66=24. 24 divided by 2 is 12.

Answer:

Since the calculated value of F = 1.4397 is less than the critical value of

F (9,9)= 2.4403 we conclude that the  first instructor's variance is smaller and reject H0.

Step-by-step explanation:

1)Formulate the hypothesis that first variance is equal or greater than the second variance

H0: σ₁²≥σ₂²  against the claim  that the first instructor's variance is smaller

 Ha: σ₁²< σ₂²

2) Test Statistic F= s₂²/s₁²

F= 84.8/ 58.9=  1.4397

3)Degrees of Freedom = n1-1= 10-1= 9  and n2 = 10-1= 9

4)Critical value   at 10 % significance level= F(9,9)= 2.4403

5)Since the calculated value of F = 1.4397 is less than the critical value of

F (9,9)= 2.4403 we conclude that the  first instructor's variance is smaller and reject H0.

Step-by-step explanation:

325 + 12 =

325 + 12 = 337

Answer: 337

So this means it isn´t 39

Answer:

1.

cos ∅=b/h=24/25

:.b=24

h=25

by using Pythagoras law

h²=p²+b²

25²=p²+24²

p²=25²-24²

p=√7²=7

now

sin ∅=P/h=7/25

tan∅=p/b=7/24

2.cos ∅ is your answer

sec∅-sin∅tan∅

1/cos∅-sin²/cos∅

(1-sin²∅)/cos∅

cos²∅/cos∅

cos∅

3.

tan²∅-sec²x

sin²∅/cos²∅-¹/cos²∅

(sin²∅-1)/cos²∅
