Answer 1

Answer:  Its 1/30

Step-by-step explanation: 1 of ten of the red and 1/3 is red out of the others.

Answer 2
The odds of pulling a red ball out of a bag of 30 balls in which 10 are red can be calculated as follows:

First, we need to determine the total number of possible outcomes, which is the number of balls in the bag:

Total number of possible outcomes = 30

Next, we need to determine the number of favorable outcomes, which is the number of red balls in the bag:

Number of favorable outcomes = 10

Therefore, the odds of pulling a red ball out of the bag can be expressed as:

Number of favorable outcomes / Total number of possible outcomes

= 10/30

= 1/3

So the odds of pulling a red ball out of the bag are 1 in 3 or 1/3.

Is -4/5 rational or irrational

Answers

Answer: Rational

Step-by-step explanation:

The number -0.8 is rational if it is an integer or decimal

A rational number is a number that can be represented as a/b where a and b are integers and b is not equal to 0.

Since -0.8 is an integer or decimal from above, -0.8 is also a rational

An irrational number is a number that cannot be expressed as a ratio between two integers and is not an imaginary number.

Answer:

It is a rational number

Step-by-step explanation:

An irrational is a number that repeats in a sequence or not.

It is a number that never stops. ex. pi, 2/3.

-4 divided by 5 is -0.8 which is a rational number

What is 20% of 90?
Thank u!

Answers

Answer:

18

Step-by-step explanation:

20% × 90. = 20/100 × 90. = 18

formula: Y/X = P%
X is 60, Y is 12, so the equation is 12/60 = P%
Do the math: 12/60 = 0.20.
Important! ...
Converting 0.20 to a percent: 0.20 * 100 = 20%
So 20% of 60 is 12.



20% of 90 is 18

The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

What is constant of Proportionality?

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Answer:

Answer B

Step-by-step explanation:

You need to first find the surface area of the triangular prism.

In order to do that, we need to first know the length of the base of the triangles on both side. So, I used the pythagorean theorem (a²+b²=c²) after making the triangle a right triangle by cutting it in HALF.

a²+b²=c²

a²+2.6²=3²

a²+6.76=9

Subtract 6.76 on both sides

a²=2.24

a=√2.24

a=1.49666295471

Now, we know that the base of HALF of the triangles on both sides of the prism is 1.496......

We need to MULTIPLY this by 2 to get the full length. So, the length of the bases of both triangles is 2.99332590942

The height of the triangles is 2.6

We are going to first find the area of one triangle and multiply it by 2, to get the area of both triangles.

Area of a triangle = base x height ÷ 2

2.6 x 2.99332590942= 7.78264736449

7.78264736449 ÷ 2 = 3.89132368224

3.89132368224 x 2 (because we have 2 triangles) =7.78264736449  cm squared

Now, we know the area of both triangles, but we now need to add the add the surface area of the rectangles in the net.

Area of a rectangle = length x width

We know that all of the three rectangles are equal in size, and that the length of each one of them is 15 cm. However, the width/height of each one is unknown. We will find out the height of each one by looking at the length of the base of the triangle attached to the first one. We know that because of the base of the triangles = 2.99332590942, the width of the attached rectangles are 2.99332590942. We found this using the Pythagorean theroem (look above).

15 x 2.99332590942= 44.8998886413

44.8998886413 x 3 (because we have 3 of the same rectangles)= 134.699665924 cm squared

Now, we must ADD the surface area of the rectangles AND the triangles.

7.78264736449 (triangles) + 134.699665924 (the three rectangles)= 142.482313288 cm squared.

The CLOSEST OPTION to the answer we got is ANSWER B because it is 142.8 cm squared, which is the closest to the answer we got which was 142.482313288 cm squared.

Answers

Answer: Least To Greatest: 1/3, 3/8, 0.625, 75%.

Step-by-step explanation: If you want to find these values in order from least to greatest, then you‘ll have to find each of their values in either decimal form or fraction form, but I recommend converting them to decimal form. 1/3 = 0.33333, 3/8 = 0.375, 0.625, 75% = 0.75. So, now you can arrange them in order, just remember to re-convert them to the form they were originally in.

least to greatest is 1/3, 3/8, .625, 75%

Answer:

5/31

Step-by-step explanation:

By getting the reciprocal of a mixed number, first you must convert it into

an improper fraction. To make that happen, first is you multiply the

denominator and the whole number and after that, you add the value of

the numerator. Lastly copy the denominator, and interchange.

For example: 6 1/5

denominator (d) = 5, numerator (n) = 1, whole number (w) = 6

Sol: (d)x(w) = (5)x(6) = 30

     (dw) + (n) = 30 + 1 = 31

Therefore, it is 31/5, and now interchange the denominator and numerator, so it becomes 5/31.

If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?

Step-by-step explanation:

x hours to go to the river

0.25-x hours to come back, since 15 minutes is 0.25 hr.

to the river 40 mph * x hours =40x miles

from the river 70 mph (0.25-x) hours=17.5-70x

those two are equal

40x=17.5-70x

110x=17.5

x=17.5/110=0.159 hours

The answer is a because when you’re dealing with positive Powers you do the one on the left first and when you do the one on the left you divide the second number by two and the second number 8 so now it is four. The one on the right you double the second number by two and the second number was four so now it is eight and when the number outside of the parentheses is negative you don’t do anything with it so that is why your answer is a.

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.
