Answer:

The one on the top right side

Step-by-step explanation:

A graph with a negative slope is a graph that "decreases" in y value when the x values "increases".

I'm the top right graph, the y value changes from 8 to 6, the x value changes from 0 to 4.

Also if you trace the 1 on the x axis upward until it touches the graph , you'll see that , that's where you'll see the 6 on the y axis. That's why The graph passes through (1,6).

Answer:

It takes the word processor 117 minutes to word process and spell check 27 pages.

Step-by-step explanation:

With the information provided, you can use a rule of three to find how long it would take to word process and spell check 27 pages given that it takes 26 minutes to word process and spell check 6 pages:

6 pages   →  26 minutes

27 pages  →          x

x=(27*26)/6=117 minutes

According to this, the answer is that it takes the word processor 117 minutes to word process and spell check 27 pages.

Answer:

Hope it works for u

Step-by-step explanation:

its so simple first to find the total cost for 1 sandwich

for 1 sandwich+ delivery charges

total cost for 1 sandwich= delivery charges+ sandwich cost

                                          =$10+4.50 =$14.50

Now to get total cost for 5 sandwich and also delivery charges is on each sandwich hence simply multiply total cost by 5,we get

Total cost for 5 =  5*($14.50)=$72.5 Ans.....

Answer:

x=39

Step-by-step explanation:

The sum of the measure of all of the interior angles of a triangle is equal to 180 degrees. If a triangle has angle measures known to be 102 and 39 degrees, in order to find the last angle measure an equation can be used such as [tex]x=180-102-39[/tex]. When solving this equation the third angle measure is x, which is revealed to be 39 degrees.

Step-by-step explanation:

Answer:

there are 16 ounces in a pound and 24 hours in a day.

22*16= 352oz/day

352/24 = 14.66666 oz/h

i would round up because it has the about symbol. so your answer is:

15 oz/h

Step-by-step explanation:

i multiplied 22 by 16 to find out how many ounces were in 22 pounds.

i divided 352 by 24 because there's 24 hours in a day and i needed how many ounces for one hour.

Answer:

122 oz a day is the aswer

Answer:

The person must leave the money for approximately 14.8 years.

Step-by-step explanation:

This can be calculated using the formula for calculating the future value as follows:

FV = PV * (1 + r)^n …………………………………. (1)

Where;

FV = Future value of the investment = 5600

PV = Present value of the investment = 3000

r = semiannual interest rate = 4.25% / 2 = 0.0425 / 2 = 0.02125

n = number of semiannuals = ?

Substitute the values into equation (1) and solve for n, we have:

5600 = 3000 * (1 + 0.02125)^n

5600 / 3000 = 1.02125^n

1.02125^n = 1.86666666666667

Loglinearizing both sides, we have:

nlog1.02125 = log1.86666666666667

n = log1.86666666666667 / log1.02125

n = 0.271066772286539 / 0.0091320695404719

n = 29.6829509548973

Since n is number of semiannuals, we divide the answer by 2 obtain the number of years as follows:

Number of years = 29.6829509548973 / 2 = 14.8414754774487

Rounding to the nearest tenth of year, we have:

Number of years = 14.8

Therefore, the person must leave the money for approximately 14.8 years.

Answer:

4x²+20x+25

Step-by-step explanation:

(2x+5)² = (2x+5)(2x+5)

(2x+5) (2x+5) = 2x(2x) + 2x(5) + 5(2x) + 5(5)

= 4x² + 10x + 10x + 25

= 4x²+20x+25

Answer:

Marsha earned interest = $850

Step-by-step explanation:

Amount deposited = $8500

Time = 2 years

Interest rate = 5% = 0.05

We need to find how much did Marsha earn in interest

The formula use is: [tex]I=P\times r \times t[/tex]

Where I is interest earned, P is amount deposited, r is interest rate and t is time.

Putting values and finding interest.

[tex]I=P\times r \times t\\I=8500\times 2\times 0.05\\I=850[/tex]

So, Marsha earned interest = $850

Answer:

  85°

Step-by-step explanation:

The sum of arcs in a circle is 360°.

  FG +140° +80° +55° = 360°

  FG = 360° -275°

  FG = 85°

Step-by-step explanation:

Since the sum of the digits must be an integer, the number itself must also be a multiple of 5.

Lowest common multiple of 5 and 9 = 45.

Therefore the number could be 45 or 90.

5(9 + 0) =/= 90, so 90 is incorrect.

Since 5(4 + 5) = 45, 45 is the answer.

Answer: 45

Step-by-step explanation:

We know that it has to be a 2-digit number. Its the multiple of 9. We see there is a number in the question. Five. I simply took 9 and multiplied it by 5 which gave me a total of 45.

Answer:

8 2-point shots and 4 3-point shots

Step-by-step explanation:

Anthony scored 28 points with 12 baskets. Saying that, (with x-y representing 2 point shots-3 point shots) any combination with a supermajority (at least 75% of) of either shot is out. This leaves just 5 possible combinations. 8-4, 7-5, 6-6, 5-7, and 4-8. Multiply the first number by 2 and the second by 3.

(4 * 2) + (8 * 3) = 8 + 24 = 32 points, so no.

(5 * 2) + (7 * 3) = 10 + 21 = 31 points, so no.

(6 * 2) + (6 * 3) = 12 + 18 = 30 points, so no.

(7 * 2) + (5 * 3) = 14 + 15 = 29 points, so no as well.

(8 * 2) + (4 * 3) = 16 + 12 = 28 points, so this is the combination we're looking for.
