Please help me give me the explanations of them not just the answer and yes I’m giving 24 points

Answers

Answer:

well the middle on is 3

Step-by-step explanation:

First questions answer is:

23.4 - 8.78 = 14.62

you subract 23.4 by 8.78. Since the number 23.4 is bigger than 8.78, the answer is not negative.

how you subtract the two numbers are you line up the decimal points, and then add a 0 next to the 4 in the term 23.4, and just subtract the two terms, 8.78.

Second question answer is:

if you add 2+4 you get 6.

Third question answer is:

$110

you add 47.91 + 23.96 + 35.09 and you get 106.96, which is closest to 110, so She spent about $110

Answers

Answer:

Step-by-step explanation:

Four less refers to subtracting 4 from a number.

So D is not the answer.

The quotient of 12 and y is division. 12/y

So A and B is not the answer.

An image of a rocket is shown. The rocket is made up of a triangle, a rectangle, and a trapezoid. The triangle at the top of the rocket has a base of length 3 inches and a height of 4 inches. The rectangle in the middle of the rocket has a height of 10 inches and a length of 3 inches. The trapezoid at the bottom of the rocket has one base of length 3 inches at the top, another base of length 5 inches at the bottom, and a height of 2 inches.

Use familiar figures to find the area of the figure shown. Show all work

Answers

Answer

the area of the entire rocket is 44

area of the triangle=6

area of the rectangle=30

area of the trapezoid=8

Step-by-step explanation:

triangle= bxh/2 so 4x3= 12/2= 6

rectangle= bxh so 3x10=30

trapizoid= A=a+b2h so 3+5= 8/2= 4x2= 8

Zahra cuts out a rectangle that has a perimeters of 22 inches and a length of 9 inches she cuts another rectangle that is the same length and twice as wide.

Answers

Answer:

The first rectangle that Zahra cuts out has a perimeter of 22 inches and a length of 9 inches. To find the width of this rectangle, we can use the formula for the perimeter of a rectangle:

Perimeter = 2(length + width)

Substituting in the given values, we have:

22 = 2(9 + width)

Simplifying and solving for width, we get:

width = 2 inches

Therefore, the dimensions of the first rectangle are 9 inches by 2 inches.

Zahra then cuts another rectangle that is the same length (9 inches) but twice as wide as the first rectangle. Therefore, the width of this second rectangle is:

2 x 2 inches = 4 inches

So, the dimensions of the second rectangle are 9 inches by 4 inches.

In summary, Zahra has cut out two rectangles with dimensions as follows:

- Rectangle 1: Length = 9 inches, Width = 2 inches

- Rectangle 2: Length = 9 inches, Width = 4 inches

5 2,430
Complete each of the 2 activities for this Task.
Activity 1 of 2
Write an equation where y represents the number of rabbits in x years.

Activity 2 of 2
A second population of 10 rabbits is placed in a second enclosed wildlife ranch and doubles each year.

Select all statements that are TRUE when comparing the equation of the second group of rabbits to the first group.

A.
The base of the exponent will change from 3 to 2.

B.
The function will become quadratic.

C.
The y-intercept will change.

D.
The second population will increase less rapidly.

Answers

Answer:

Step-by-step explanation:

First, we have to find the equation that will give the rabbit population as a function of time and the initial population.

The equation we need turns out to be Population = a0 x 3y where a0 is the initial population and y is the number of years,

To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.

You can now find the difference in the number of rabbits at year 3 for the different starting populations.

Which of the following represents a 1.00 M (M = mol/dm3) aqueous solution of glucose (C6H12O6)?

A. 180 g glucose per 1000 cm3 solution

B. 10.0 g glucose per 10.0 cm3 water

C. 90.0 g glucose per 500 cm3 water

D. 0.100 g glucose per cm3 solution

Answers

Answer:

Option C. 90.0 g glucose per 500 cm3 water

Step-by-step explanation:

1.00 M (mol/dm3) aqueous solution of glucose (C6H12O6) means that 1 mole of glucose is dissolved in 1dm³ (1000cm³) of water.

The concentration of a substance is defined as the mole of solute per unit volume of solvent (water) in dm³.

Option A is wrong since it state: 180g of C6H12O6 per 1000cm³ of solution. Concentration is always expressed as per 1000cm³ or dm³ of water.

For option B:

We shall determine the number of mole of C6H12O6, followed by the concentration.

This is illustrated below:

Molar mass of C6H12O6 = (12x6) + (12x1) + (16x6) = 180g/mol

Mass of C6H12O6 = 10g

Mole = Mass /Molar Mass

Mole of C6H12O6 = 10/180 = 0.056 mole.

Volume of water = 10cm³ = 10/1000 = 0.01dm³

Concentration = mole /Volume

Concentration = 0.056/0.01 = 5.6mol/dm³

Option B is wrong

For option C:

We shall determine the number of mole of C6H12O6, followed by the concentration.

This is illustrated below:

Molar mass of C6H12O6 = 180g/mol

Mass of C6H12O6 = 90g

Mole = Mass /Molar Mass

Mole of C6H12O6 = 90/180 = 0.5mole

Volume of water = 10cm³ = 500/1000 = 0.5dm³

Concentration = mole /Volume

Concentration = 0.5/0.5 = 1mol/dm³

Option C is correct.

For option D is wrong as well as it states 0.1g of C6H12O6 per cm³ of solution. Concentration is always per 1000cm³ or dm³ of water.

From the above illustrations, option C is the correct answer.

40 - 25 = 15

(5/2)² = 5²/2²

edward deposited $7,500 into a savings account 5 years ago. The simple interest rate is 5%. How much money did earn in interest?

Answers

Answer:

Edward earned $1,875 in interest.

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

Here, p = $7,500, r = 0.05 and t = 5 years, and so the interest earned was

i = ($7,500)(0.05)(5) = $1,875.

Edward earned $1,875 in interest.
