Double check:

80(0.15) = 12

Answer:

g=-1

Step-by-step explanation:

3(g+4)=9

Divide both sides by 3.

g+4=  9/3

Divide 9 by 3 to get 3.

g+4=3

Subtract 4 from both sides.

g=3−4

Subtract 4 from 3 to get −1.

g=−1

Answer:

3(g+4)=9

or, 3(g+4)/3=9/3 [Dividing both sides by 3.]

or, g+4=3

or, g+4-4=3-4 [Subtracting 4 from both sides.]

So, g=-1

Answer:

108,000,934

1.08934×10^8

Step-by-step explanation:

(302)^3

(a+b)^3

(a+b)^3==a^3+3a^2b+3ab^2+b^3

(300+2)

(300)^3+3(300^2+2)+3(300+2^2)+2^3

27,000,000+81,000,002+8+924

108,000,002+8+924

108,000,934 or 1.08934×10^8

Answer:

Step-by-step explanation:

3 a) 6

3 b) 12

3 c) 12

4 a) 4/5

4 b) 10/9

4 c) 17/15

Answer:

b = 2/5f

Step-by-step explanation:

Cups of flour = loaves of bread

7 1/2 c = 3

c = 3 ÷ 7 1/2

c = 3 ÷ 15/2

= 3 × 2/15

= 6/15

= 2/5

c = 2/5

Cups of flour = loaves of bread

2/5 f = b

b = 2/5f

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]y = 0.554x - 0.507[/tex]

The question is incomplete; however, a possible question could be to interpret the given equation.

The equation is given in slope intercept form i.e. [tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

[tex]b = y\ intercept[/tex]

So, by comparing:

[tex]y = mx + b[/tex] to [tex]y = 0.554x - 0.507[/tex]

[tex]m = 0.554[/tex]

[tex]b = -0.507[/tex]

Hence, the slope of the regression is 0.554 and the y intercept of -0.507

Answer:

n = 4

Step-by-step explanation:

Given

[tex]\sqrt{64}[/tex] × [tex]\sqrt[3]{8}[/tex]

= 8 × 2

= 2³ × [tex]2^{1}[/tex]

= [tex]2^{(3+1)}[/tex]

= [tex]2^{4}[/tex] → with n = 4

Answer:

72 kg

Step-by-step explanation:

For concreatting a tower cement, sand, stones are in the ratio 1:2:4 For 144kg sand.. What amount of cement is required?

We are given the ratio

cement: sand:stones

= 1:2:4

The sum of proportion =

1 + 2 + 4 = 7

We are given the kg of sand = 144kg

Step 1

We find the total kg of cement, sand and stones = x

Using the proportion of sand,

2/7 of x = 144kg

2/7 × x = 144kg

2x/7 = 144kg

Cross Multiply

2x = 7 × 144kg

x = 7 × 144kg/2

x = 504kg

Therefore the total kg of cement, sand and stone = 504kg

Step 2

The amount of cement required is calculated as:

1/7 × 504 kg = 72 kg

Therefore, 72kg of cement is required.

Answer:

Not enough information

Step-by-step explanation:

So, we first know that the bike costs 250 dollars. We also know that he babysat for 15 hours, and mowed the lawn 5 times. However, we do not know how much money he has, or how much he made. Sure, doing extra chores could of made him money, but in this question it doesn't say how much money he made. Therefore, we cannot answer this question because, although we have the value of the bike's cost, we do not know how much Razi has. Hope this helps you!

Step-by-step explanation:

A right - angled triangle is one which has one of its angles being 90°. Once we have a right angled triangle, the rule of Pythagoras can be applied in other to solve problems relating to obtaining sides of the triangle while trigonometric relations including :

Sinθ = opposite / hypotenus

Tanθ = opposite / Adjacent

Cosθ = Adjacent / Hypotenus

To obtain the angle θ; depending on which of the sides are given.

From Pythagoras :

c² = a² + b²

Where, c = hypotenus and the longest side if the triangle.
