Find the proportion please answer number 5. 6. 8. And 9. :)

Answers

Answer 1

Answer:

Answer:

5. 28

6. 6

8. 1,232

9. 2

Step-by-step explanation:

When you know both numerators (the numbers on top) or both denominators (numbers on bottom), you can divide the second by the first and then apply that to the other side. For example, on question five, I divided twenty by fifteen. The answer is 1.33333... or $1(1)/(3)$ , or $(4)/(3)$ . So I multiply 21 by this number and my answer is 28. If visualization helps:

$(15)/(21) =(20)/(y)$

Step 1: 20 ÷ 15 = $(4)/(3)$ (second number divided by first number, using the side where we know both numbers)

Step 2: 21 × $(4)/(3)$ = 28 (y = 28. solved!)

You can do the same thing on question nine, even though the known numbers are on the bottom instead of the top. Fifteen divided by 120, then multiply sixteen by your answer - 0.125 - and you will see that j (i?) = 2 :)

If you have any questions, feel free to ask. Hope this helped!

Julia's great dane weighs 45 kgand Jake's chihuahua weighs 15 kg. How much bigger, as a percentage, is julia's dog?

Answers

Answer : The percentage will be, 200%

Step-by-step explanation :

First we have to calculate the excess weight.

Excess weight = 45 kg - 15 kg

Excess weight = 30 kg

Now we have to calculate the percentage of excess weight.

Percentage of excess weight = $\frac{\text{Excess weight}}{\text{Weight of Jake's}}* 100$

Percentage of excess weight = $(30kg)/(15kg)* 100$

Percentage of excess weight = 200 %

Therefore, the percentage will be, 200%

45kg-15kg=30kg Percentage: 30kg=0.3% Percentage =0.3%

Simplify, 5(2x + 3y) - 4(3x - 5y)

Answers

5(2x + 3y) - 4(3x - 5y)

5(2x) + 5(3y) - 4(3x) + 4(5y)

(10x + 15y) + (-12x + 20y)

(10x - 12x) + (15y + 20y)

-2x + 35y

Answer:

$-2x+35y$

Step-by-step explanation:

$5\left(2x+3y\right)-4\left(3x-5y\right)$

Expand:-

$\hookrightarrow 10x+15y-4\left(3x-5y\right)$

$\hookrightarrow 10x+15y-12x+20y$

Combine $10x$ and $-12x$ = $-2x$

$\hookrightarrow -2x+15y+20y$

Combine $15y$ and $20y$ = $35y$

$\hookrightarrow -2x+35y$

Please help.Whats thr volume of a right pyramid whose base is a square with a side 6m long and whose altitude is equal to the base side?

Answers

Answer: $72\text{ cubic meters}$

Step-by-step explanation:

Given: The base of the right pyramid is square with side = 6 m

Since, the altitude (h) is equals to the base , thus h=6m.

We know that the volume of the square pyramid is given by :_

$\text{Volume}=(1)/(3)a^2h$ , where a is the side of the square.

Then, the volume of the given right pyramid is given by :_

$\text{Volume}=(1)/(3)(6)^2(6)\n\n\Rightarrow\ \text{Volume}=72\text{ cubic meters}$

V=(1/3)(area of the base)(altitude)

V=(1/3)(6²)(6)= 72 m³
