Which of the following expression is not equivalent to -4.5 times -8?

Answer:

H

Step-by-step explanation:

Let a represent Ann's height, and let j represent Jay's height

Break up the sentence into the key parts.

"The difference between Ann's and Jay's heights" "is" "half of Jay's height"

"The difference between Ann's and Jay's heights" becomes the expression:

         a - j

"is" is math means an equal sign '='

"half of Jay's height" becomes the expression: (1/2)j

Put the 3 parts together and get the equation:

a - j = (1/2)j,

Since all the equations in the answer choices are in terms of a, solve the above equation for a...

a = (1/2)j + j, which is answer H

Step-by-step explanation:

The total time for the student's total trip is A = 58 minutes

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is = total time for the trip

Substituting the values in the equation , we get

The total length of the bus route is 57 minutes. The student is taking a trip for 2/3 of the total route length, which is (2/3) x 57 = 38 minutes

In addition to the time on the bus, the student must also walk 10 minutes to get to the bus and 10 minutes from the bus to his destination.

Therefore, the total time for the student's trip is:

38 minutes (on the bus) + 10 minutes (walking to the bus) + 10 minutes (walking from the bus) = 58 minutes

Hence , the time for student's trip is A = 58 minutes

We are making a equation equal 0

The answer to this is the last one as it shows that not is not larger than 9 but it can equal to it. This makes the original statement true

Answer:  The correct option is

(D) [tex]n\leq 9.[/tex]

Step-by-step explanation:  We are given that the greatest value of n is 9.

We are to select the inequality that best shows all the possible values of n.

Since the greatest value of n is 9, it means that the value of n is less than or equal to 9.

But the values of n cannot be greater than 9.

So, we will be using the sign of less than or equal to in the inequality.

Therefore, the required inequality that best shows all the possible values of n is given by

[tex]n\leq 9.[/tex]

Thus, (D) is the correct option.

There were about 6001 bacteria X bring introduced into the egg salad. The number of bacteria in the food 4 hours after contamination is 63000.

To find the initial number of bacteria X introduced into the egg salad, divide the final number by (1 + growth rate)^time. For estimating the number of bacteria in the food 4 hours after contamination, multiply the initial number by (1 + growth rate)^time.

To find the initial number of bacteria X introduced into the egg salad, we can use the formula:

Initial Number = Final Number / (1 + Growth Rate)^Time

Plugging in the given values, we have:

Initial Number = 35,000 / (1 + 180%)^3 = 35,000 / (1 + 1.8)^3 = 35,000 / 3.027 = 11,542.52

To estimate the number of bacteria in the food 4 hours after contamination, we can use the same formula:

Number after 4 hours = Initial Number * (1 + Growth Rate)^Time

Plugging in the values, we have:

Number after 4 hours = 11,542.52 * (1 + 180%)^4 = 11,542.52 * (1 + 1.8)^4 = 11,542.52 * 10.4044 = 120,108.83

2. 16 cm and 45 cm cone

3. 0.9 Fl oz

4. the cone still

Step-by-step explanation:

The volume of each vase can be determine by using volume formula of sphere, cone and cylinder.

(1) The volume of sphere is [tex]972\pi[/tex], volume of cone is [tex]960\pi[/tex] and volume of cylinder is [tex]1000\pi[/tex].

(2) You should purchase the cylinder vase.

(3) The largest vase hold [tex]40 \pi \:{\rm cm}^3[/tex] more than smallest vase.

(4) If the diameter decreases by 2 cm, then cone holds more water.

Given:

Diameter of cylinder is [tex]d=10 \:\rm cm[/tex].

Height of cylinder is [tex]h=40\:\rm cm[/tex].

Diameter of cone is [tex]d=16 \:\rm cm[/tex].

Height of cylinder is [tex]h=45\:\rm cm[/tex].

Diameter of sphere is [tex]d=45 \:\rm cm[/tex].

(1)

Calculate the volume of cylinder.

[tex]\begin{aligned}\mbox{Cylinder Volume} &= \pi r^2 h\\& = \pi(5)^2(40) \text{ cm}^3\\&= 1000 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of Cone.

[tex]\begin{aligned}\mbox{Cone Volume} &= \frac13 \pi r^2 h\\&= \frac13 \pi(8)^2(45) \text{ cm}^3\\&= 960 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of sphere.

[tex]\begin{aligned}\mbox{Sphere Volume} &= \frac43 \pi r^3\\&= \frac43 \pi (9)^3 \text{ cm}^3\\&= 972 \pi \text{ cm}^3.\end{align}[/tex]

(2)

Since the volume of cylinder is higher than the volume of sphere and cone. So, you should purchase cylinder vase.

(3)

The largest vase hold water more than the smallest vase is,

[tex]\text{Cylinder Volume} - \text{Cone Volume} = 1000 \pi \text{ cm}^3 - 960 \pi \text{ cm}^3 = 40 \pi \text{ cm}^3[/tex]

(4)

As per the question if diameter of each vase decreases by 2 cm then radius decreases by 1 cm.

Calculate the volume of cylinder.

[tex]\begin{aligned}\mbox{Cylinder Volume} &= \pi r^2 h\\&= \pi(4)^2(40) \text{ cm}^3\\&= 640 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of Cone.

[tex]\begin{aligned}\mbox{Cone Volume}&= \frac13 \pi r^2 h\\&= \frac13 \pi(7)^2(45) \text{ cm}^3\\&= 735 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of sphere.

[tex]\begin{aligned}\mbox{Sphere volume} &= \frac43 \pi r^3\\&= \frac43 \pi (8)^3 \text{ cm}^3\\&= 682 \frac23 \pi \text{ cm}^3.\end{align}[/tex]

Step-by-step explanation:

Answer:

the answer is 28.26

Area = Base x Width ÷ 2

Area = 32cm^2

Base = 8cm

32 ÷ 8 = 4

4 × 2 = 8

Answer = 8

To check our answer:

8 x 8 = 64

64 ÷ 2 = 32

To find the height of a triangle with an area of 32 square centimeters and a base of 8 centimeters, we use the formula A = 1/2 × base × height. The height is calculated to be 8 centimeters.

The student has asked about finding the width of a triangle, given its area in square centimeters and the length of its base. There seems to be a confusion with the terminology; the width of a rectangle is being referred to instead of the triangle's height. However, to provide assistance with the appropriate concept, we will focus on finding the height of a triangle.

The area of a triangle is calculated by the formula A = 1/2 ×base× height. When we know the area and the base length, we can rearrange the formula to solve for the height. For a triangle with a base of 8 centimeters and an area of 32 square centimeters, the calculation would be as follows:

Area = 1/2 × base × height
32 = 1/2 × 8 × height
32 = 4 × height
height = 32 / 4
height = 8 centimeters

Therefore, the height of the triangle would be 8 centimeters.

A multiple of a number is a number multiplied by another number.

Considering this definition, the first three multiples of 6 are 6, 12, and 18 because it is six multiplied by 1, 2, and 3.

Answer:

5/100, .05

Step-by-step explanation:

The decimal form remains 0.5, but when expressed with a denominator of 100, it becomes 50.0%.

To express 0.5 as hundredths in fraction form, you convert the decimal to a fraction with a denominator of 100. Since 0.5 is equivalent to 50%, you would write this as 50/100. This fraction can also be simplified to 1/2 by dividing both the numerator and the denominator by 50.

In decimal form, 0.5 is already represented as a decimal and does not require conversion. However, if we are to express it with a denominator of 100, we simply move the decimal point two places to the right (multiplying by 100), yielding 50.00, which can then be represented as 50.0% when expressing as a percent.

David reads 80 pages every day.

Karen reads 25% more pages every day than David reads.

So, Karen reads [tex]\frac{25}{100}*80= 20[/tex] more pages. She reads a total of 80 + 20 =100 pages.

Rick reads 35% fewer pages per day than Karen. So, Rick reads [tex]\frac{35}{100}*100=35[/tex] less pages than Karen. He reads 100 - 35 =65 pages

So, in total the tree friends read = 80+100+65=245 pages.
