NEED AS SOON AS POSSIBLE!!! Kaylee is mixing paint for an art project. She mixes 5 ounces of green paint with every 3 ounces of white paint. She needs 50 ounces of the paint mixture. I need it as a equation

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Let Kaylee used the amount of green paint in the mixture = x ounces

and the amount of white paint = y ounces

Total amount of mixture = 50 ounces

Equation will be x + y = 50 ------(1)

Ratio of green paint to the white paint in the mixture = 5 : 3

⇒ x : y = 5 : 3

⇒ $(x)/(y)=(5)/(3)$

⇒ x = $(5)/(3)y$ ---------(2)

Therefore, By solving these two equations by substitution method we can get the amount of green and white paint used in the mixture.

The diameter of a Frisbee is 12 in. What is the area of the Frisbee?a. 37.68 sq. in.
b. 452.16 sq. in.
c. 18.84 sq. in.
d. 113.04 sq. in.

Answers

we know that

Area of the circle is equal to

$A=\pi r^(2)$

where

r is the radius

in this problem

$diameter=12\ in \n radius=diameter/2\n radius=12/2\n radius=6\ in$

$A=3.14* 6^(2)$

$A=113.04 in^(2)$

therefore

the answer is the option

d. 113.04 sq. in.

The area of the Frisbee is about 113 in.² ( Option D )

Further explanation

The basic formula that need to be recalled is:

Circular Area = π x R²

Circle Circumference = 2 x π x R

where:

R = radius of circle

The area of sector:

$\text{Area of Sector} = \frac{\text{Central Angle}}{2 \pi} * \text{Area of Circle}$

The length of arc:

$\text{Length of Arc} = \frac{\text{Central Angle}}{2 \pi} * \text{Circumference of Circle}$

Let us now tackle the problem!

Given:

Diameter of Frisbee = d = 12 in

Unknown:

Area of Frisbee = A = ?

Solution:

Area of the Frisbee could be calculated using the area of circle as follows:

$A = (1)/(4) \pi d^2$

$A = (1)/(4) * \pi * 12^2$

$A = 36 \pi ~ in.^2$

$A \approx \boxed {113.10 ~ in.^2}$

The closest option available will be option D. 113 in.²

In a school, the ratio of musicians to athletes is 3:1. which statement is true13 of the total students are musicians.

If there are 18 people, then 12 of them are athletes.

If there are 3 athletes, then there are 12 musicians.

The number of musicians is 3 times the number of athletes

Answers

I think the correct answer from the choices listed above is the last option. In a school, the ratio of musicians to athletes is 3:1. This means that the number of musicians is 3 times the number of athletes. Hope this answers the question. Have a nice day.

Answer: The answer is (D) The number of musicians is 3 times the number of athletes.

Step-by-step explanation: Given that the ratio of musicians to athletes in a school is 3 : 1. We are to select the correct statement out of the given four options.

Since the total number of people are not given, so we cannot say that 13 of them are musicians. Therefore, option (A) is incorrect.

If there are 18 people, then number of athletes is given by

$(x)/(x+3x)* 18=4.5\neq 12,$

and hence the option (B) is not correct.

If there are 3 athletes, then

x=3, and so the number of musicians = 3 × 3 = 9 ≠ 12. Therefore, the option (C) is not correct.

Number of musicians = 3x = 3 × x = 3 × number of athletes.

Thus, the correct option is (D) The number of musicians is 3 times the number of athletes.

A bag of chips costs $3.79 including tax Mr.Connor wants to purchase chips for his class and has a $15 budget. Write and inequality to solve for the number of bags of chips Mr.Connor can purchase with his budget A. $15x > $3.79 B.$15x < $3.79 C $3.79 > $15 D. $3.79 < $15 (There is a flat line under all the greater than and less than signs)

Answers

The inequality equation that could best express the statement will be letter d. 3.79x < 15. This is because there is only 15 budget from Mr. Connor, and his spending must not exceed the budget. Then the price per pack is 3.79, so it is express as 3.79x.

Answer:

D. $3.79x\leq 15$
