Carter has 60 balloons. 4/12 of the balloons are black, and 3/12 of the balloons are white. The rest of the balloons are red. Which series of calculations shows how many red balloons Carter has?

Answers

Let

B------------> black balloons
W-----------> white balloons
R-----------> red balloons

Step 1
calculate the amount of black  balloons and white balloons
the total of balloons is 60
B=(4/12)*60=20 balloons
W=(3/12)*60=15 balloons

Step 2
calculate the amount of red balloons
R=60-[B+W]---------> R=60-[20+15]
R=60-(35)=25 balloons

the answer is 25 red balloons


Final answer:

To find the number of red balloons Carter has, subtract the number of black and white balloons from the total number, using fractions to represent the proportion of black and white balloons. Multiply the total number of balloons by the fraction representing red balloons to find the number of red balloons.

Explanation:

To find the number of red balloons Carter has, we need to subtract the number of black and white balloons from the total number of balloons. Since 4/12 are black and 3/12 are white, we can add these fractions together to find the total fraction of balloons that are either black or white: 4/12 + 3/12 = 7/12.

To find the fraction of balloons that are red, we can subtract the fraction of black and white balloons from 1 (since the sum of all fractions should equal 1): 1 - 7/12 = 5/12.

To find the actual number of red balloons, we can multiply the total number of balloons (60) by the fraction of red balloons: 60 x 5/12 = 25 red balloons.

Pe ling needs 2 yard of fabric for a craft project. She has 3 feet already. How many inches of fabric does she still need ?

Answers

First, you want them to be the same units. 
We'll convert yards to feet.

Since there are 3 feet in a yard 

2 yards * 3 = 6 feet

So she needs 6 yards and has 3 feet.

6-3=3     3 feet is needed

So to make things easier convert 3 feet to inches
12 in. in a foot

12*3 feet= 36 inches
She needs 36 inches of fabric
She needs 2 yards. 

2 yards = 6 feet

3 feet = 36 inches

So, she has half of it done already.
If 2 yard = 6ft, then 1 yard = 3ft.
In 1 foot, there is 12in.

Therefore, she still needs 36 inches of fabric.

Hopes this helps u :) 

Answer:

[tex]IQR=4.75[/tex]

Step-by-step explanation:

The given data is:

12,14,16,17.5,10,18,15,15.5,19

In order to find the interquartile range, we have to arrange the given data set in ascending order, thus

10, 12, 14, 15, 15.5, 16, 17.5, 18, 19

Now, the lower quartile is: 10, 12, 14, 15

Median is given as:

[tex]M=\frac{14+16}{2}=\frac{26}{2}=13[/tex]

And the upper quartile is given as:

16, 17.5, 18, 19

Median is given as:

[tex]M=\frac{17.5+18}{2}=17.75[/tex]

thus, the Interquartile range is given as:

[tex]IQR=Upper quartile-Lower quartile[/tex]

[tex]IQR=17.75-13[/tex]

[tex]IQR=4.75[/tex]

A cone - shaped building has a height of 6 meters and a base with a diameter of 10 meters. The building will be filled with road salt that costs $25 per cubic meter. How much will it cost to fill the building with road salt? Use 3.14 for π Round to the nearest hundredth HELP ME ASAP!!!!

Answers

The formula for the volume of a cone is
.. V = (1/3)*π*r^2*h
The radius (r) is half the diameter, so is 5 m. Fill in the numbers and do the arithmetic.
.. V = (1/3)*3.14*(5 m)^2*(6 m) = 157 m^3

The cost will be $25 for each of those cubic meters, so is
$25*157 = $3925.00.
Formula
V= (1/3) pi r^2 h
r = d/2 = 10/2 = 5
h = 6
pi = 3.14
V = (1/3) * 3.14 * 5^2 * 6
V = (1/3) * 471
V = 157 cubic meters.

1 cubic foot cost $25
157 cubic feet cost x Cross multiply.

x = 25 * 157
x = 3925 dollars.



Find the magnitude and direction of the vector. Round the length to the nearest tenth and the degree to the nearest unit. Diagram is not drawn to scale.

Answers

Refer to the diagram shown below.

The vector has a magnitude of a and a direction of θ degrees south of west. 

Use the Pythagorean Theorem to calculate a.
a² = (-530)² + (-200)² = 320900
a = √(320900) = 566.48 mi ≈ 566.5 mi

By definition,
tan θ = (-200)/(-530) = 0.3774
θ = tan⁻¹ 0.3774 = 20.68° ≈ 21°

Answer: about 566.5 mi; 21° south of west.

Hope I helped!
~ Zoe

60 is 20% of 300.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

Let x% be a number such that

x% of 300 is 60

This forms an equation in one variable which can be solved by transposition.

[tex]x/100\times 300=60[/tex]

Simplifying it to calculate value of x.

On multiplying 100 both sides,

[tex]300x=6000[/tex]

On dividing 300 both sides,

x=20%

Thus, 20% of 300 is 60.

The triangles are similar. So the corresponding sides form a proportion

KM/KJ = LN/LJ
(x-2)/5 = 12/8
8(x-2) = 5*12
8x-16 = 60
8x = 60+16
8x = 76
x = 76/8
x = 19/2
x = 9.5

Similarly,
MN/KL = LN/LJ
22/y = 12/8
22*8 = 12y
12y = 176
y = 176/12
y = 44/3
y = 14.667 (value is approximate)
