What would be the solution to the system of equations: y= -x + 4 y= 3x

Answers

Answer 1

Answer:

Step-by-step explanation:

The value of y is given in equation 2

Putting value of y = 3x in equation 1

Y = - x + 4

3x = - x + 4

Bringing like terms on one side

3x + x = 4

4x = 4

x = 4/4 = 1

Now putting value of x = 1 in equation 2

Y = 3x

Y = 3(1) = 3

Label each recursive routine as growth or decay (loss) and identify the percent of growth or decay.

a. Start with: 30
Rule: multiply by 1.07
growth by ????? percent


b. Start with: 100
Rule: multiply by 0.86
decay by ???? percent



c. Start with: 75
Rule: multiply by 1.125
growth by ?????? percent

Answers

Answer:

a. Rule: multiply by 1.07

1.07 = 107% = 100% + 7%

Growth by 7%

b. Rule: multiply by 0.86

0.86 = 86% = 100% - 14%

Decay by 14%

c.  Rule: multiply by 1.125

1.125 = 112.5% = 100% + 12.5%

Growth by 12.5%

Michael Phelps is one of the most decorated swimmers of all time. He has an incredible 23 gold medals. In the 2016 Olympics Michael Phelps finished ⅖ of his butterfly gold medal race, in 2 ½ minutes. Select the equation(s) that would solve how many minutes he finished the complete race in.

The formula for a area of the first semi circle is

[tex] \frac{1}{2} \times \pi {r}^{2} [/tex]

where r is the radius

Since 4 is the diameter, 2 is the radius

plug it in

[tex] \frac{1}{2} \times \pi {2}^{2} [/tex]

[tex] \frac{1}{2} \times 4\pi[/tex]

[tex]2\pi[/tex]

so the area of the first circle is 2

[tex]2\pi[/tex]

now let find the second circle

Since the semi circle is twice the area of AB the diameter is 8 so the radius is 4.

Put it in the equation.

[tex] \frac{1}{2} \times \pi {4}^{2} [/tex]

[tex] \frac{1}{2} \times \pi \times 16[/tex]

[tex]8\pi[/tex]

Now let find the third circle

Since it is twice the size of the second circle, the diameter is 16 and the radius is 8.

[tex] \frac{1}{2} \times \pi {8}^{2} [/tex]

[tex] \frac{1}{2} \times 64\pi[/tex]

[tex]32\pi[/tex]

Now let add the area of the semi circle

[tex]32\pi + 2\pi + 8\pi = 42\pi[/tex]

Amal has 1/2 pound of baked beans. She divides the beans into 8 equal servings. Write and solve an equation to find how many pounds of baked beans are in each serving

Answers

Answer:

1/16 pound or 0.0625 pound beans.

Step-by-step explanation:

According to the problem, calculation of given data are as follows,

Total baked beans = 1/2 pounds

Number of serving = 8

if distribute equal beans in each serving than,

8 serving = 1/2 pound

So, 1 serving = 1/(2×8) pound

= 1/16 pound or 0.0625 pound beans.

Hence, each serving consist of 0.0625 pound  baked beans.

Wanda, the owner of an e-commerce site, buys skateboards for $50 and then sells them on her site for $83. What is the mark-up, as a percentage?

Answers

Answer: 66%

Step-by-step explanation:

Wanda buys the boards at $50 and sells them as $83.

The markup in actual dollar amounts is:

= 83 - 50

= $33

In percentage terms, the denominator will be the cost price:

= Markup / Cost price * 100%

= 33 / 50 * 100%

= 66%
