for question b 10 acres for $175

Answers

Given :

We have $100 in our saving account and plan to deposit $12.50 each month.

Cost of 10 acres of land in mars is $175.

To Find :

How many months will it take you to save enough money to buy 10 acres of land on Mars.

Solution :

Let, after n months amount in account is :

[tex]A = 100 + 12.50n[/tex]

This A should be greater than equal to $175.

A ≥ 175

100 + 12.50n ≥ 175

n ≥ 75/12.50

n ≥ 6

Therefore, it will takes 6 months to collect such amount.

Hina drives first 120 km in 2 hrs and next 180 km in next 4 hrs. What is her

average speed for the entire trip in km per hour?

step by step explanation plz​

Answers

The average speed of the entire trip of hina in km/h is 51.42 km/h

Given ,

Distance travelled in first 2 hrs = 120 kmDistance travelled in next 4 hrs = 180 km

We need to find

Average speed

Firstly finding speed

• Speed in first 2 hrs = 120/2 = 60km/h

• Speed in next 4 hrs = 180/4 = 45 km/h

As we know that ,

Average speed = 2V₁V₂/V₁ + V₂

Substituting known values we have ,

⇒ Average speed = 2 ( 60 ) ( 45 ) / 60 + 45

⇒ Average speed = 2(60)(45)/105

⇒ Average speed = 5400/105

Average speed = 51.42 km/h

Answer:

A is always true, B is false, C is always true, D is sometimes true, E is always true, F is always true, G is always true, H is sometimes true.

Step-by-step explanation:

A: Anything greater than (>) 0 is positive. X is greater than zero.

B: X < 0 is false because X CANNOT be less than 0. It is a positive integer, meaning it has to be greater than 0.

C: X has to be greater than 0, so it has to be greater than -5 since -5 is less than 0.

D: 1 is a positive integer. We don't know what specific integer X represents. It could be 1, it could be greater than 1. It's sometimes true.

E: Any integer greater than or equal to 1 (≥) is a positive integer. X is a positive integer, so this is always true.

F: 0 is not a positive integer, so X cannot equal 0 (≠).

G: X has to be greater than 0 to be a positive integer, so it cannot equal -1 (≠) since -1 is less than 0.

H: The specific value of X is not stated, so it could be 5, it could be another positive integer. This is sometimes true.

Jaena is purchasing a new pair of shoes that coast $89. She has a coupon for $10 and a the shoes are marked 12% off. She is allowed to use the coupon and the 12% discount. How should she use the coupon and discount (what order) to get the lowest sales price? Explain your reasoning.

Answers

Answer:

She should apply the discount first.

Step-by-step explanation:

Giving the following information:

Selling price= $89

Discount rate= 12%

Coupon= $10

When you apply a percentage to increase or decrease a nominal number, the higher the number bigger the percentage. Therefore, first, we need to apply the percentage discount and the coupon.

We will demonstrate:

Discount percentage first:

Discount= 89*0.12= $10.68

Coupon= $10

Purchase price= 89 - 10.68 - 10

Purchase price= $68.32

Coupon first:

Coupon= $10

Discount= (89 - 10)*0.12= $9.48

Purchase price= 89 - 10 - 9.48

Purchase price= $69.52

Step-by-step explanation:

You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.

To solve for the full volume including the cylinder, use the cylinder's volume formula.

Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.

Volume of a cone is pi(r^2)(h/3)

Kim makes spiced tea from her mother's recipe. The recipe calls for 2 %
cups of sugar for each cup of tea. If she has only 4 cup of tea, how much
sugar should Kim use?

Answers

Using simple mathematical operations, we know that 8% of sugar is used in 4 cups.

What exactly are mathematical operations?An operation in mathematics transforms zero or more input values into precisely defined output values.The number of operands has an impact on the arity of the operation.A mathematical operation is a procedure.The mathematical operations of addition, subtraction, multiplication, division, and finding the root are a few examples.

So, % of sugar used in 4 cups:

% of sugar per cup is 2%.The number of cups she had is 4.

So, % of sugar Kim used:

2 × 4 = 8%

Therefore, using simple mathematical operations, we know that 8% of sugar is used in 4 cups.

Step-by-step explanation:

1.    200%A = 2A

B is 200% more than A means:

B = A + 200%A = A + 2A = 3A

2.    65%F = 0.65F

D is 65% more than F means:

D = F + 65%F = F + 0.65F = 1.65F

3.    250%T = 2.5T

Y is 250% more than T means:

Y = T + 250%T = T + 2.5T = 3.5T

Write an equation in slope-intercept form for the line that has the given slope and contains the point. Please show some work.( will mark brainliest)(4,-2)&(2,-1)

Answers

Answer:

An equation in the slope-intercept form will be:

[tex]y=\frac{-1}{2}x+0[/tex]

Step-by-step explanation:

Given the points

(4,-2)(2,-1)

Finding the slope between points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(4,\:-2\right),\:\left(x_2,\:y_2\right)=\left(2,\:-1\right)[/tex]

[tex]m=\frac{-1-\left(-2\right)}{2-4}[/tex]

[tex]m=-\frac{1}{2}[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

substituting the values m=-1/2 and the point (4, -2) to determine the y-intercept i.e. 'b'.

[tex]y=mx+b[/tex]

[tex]-2=\frac{-1}{2}\left(4\right)+b[/tex]

[tex]-2+b=-2[/tex]

[tex]b=0[/tex]

substituting the values m=-1/2 and b=0 to determine the line equation in slope-intercept form

[tex]y=mx+b[/tex]

[tex]y=\frac{-1}{2}x+0[/tex]

Thus, an equation in the slope-intercept form will be:

[tex]y=\frac{-1}{2}x+0[/tex]

A large university accepts 40​% of the students who apply. Of the students the university​ accepts, 25​% actually enroll. If 20,000 students​ apply, how many actually​ enroll? I’ll give BRAINLEST and free art

Answers

20000 = 100% so we need to find 1% first so we can find the 40% that will be accepted

20000 : 100 = 200 (that's 1%)

to find 40% we multiply 200×40= 8000 people accepted

we need to find the 25% of those 8000 so again we divide by 100

8000 : 100 = 80

80 × 25 = 2000 people

The solution to the system of equations be:

[tex]y=-3,\:x=2[/tex]

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}y=3x-9\\ y=-2x+1\end{bmatrix}[/tex]

Let us solve the system by the elimination method

[tex]\begin{bmatrix}y=3x-9\\ y=-2x+1\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-3x=-9\\ y+2x=1\end{bmatrix}[/tex]

subtracting the equations

[tex]y+2x=1[/tex]

[tex]-[/tex]

[tex]\underline{y-3x=-9}[/tex]

[tex]5x=10[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}y-3x=-9\\ 5x=10\end{bmatrix}[/tex]

solve 5x for x

[tex]5x=10[/tex]

Divide both sides by 5

[tex]\frac{5x}{5}=\frac{10}{5}[/tex]

[tex]x = 2[/tex]

[tex]\mathrm{For\:}y-3x=-9\mathrm{\:plug\:in\:}x=2[/tex]

[tex]y-3\cdot \:2=-9[/tex]

[tex]y-6=-9[/tex]

Add 6 to both sides

[tex]y-6+6=-9+6[/tex]

[tex]y=-3[/tex]

Therefore, the solution to the system of equations be:
