Answer:

85,750 x 6% = $5,145.00

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Positives are bigger than negatives, so the highest is 4 and the lowest is Negative 6.

Answer:

c is the answer

Step-by-step explanation:

because when the number is negative it's lowe than a positive number and the answer "c" has the first number as a positive which that number is the greatest out of all of them in that answer

Answer:

more than.

"a top speed in excess of 20 knots"

Similar:  "more than"  "over"  "above"  "over and above"  "beyond"

Answers:

Each answer has 7 as the base and a fraction as an exponent.

==========================================================

Explanation:

One useful rule here is that [tex]\sqrt[n]{x^m} = x^{m/n}[/tex]. The fraction m/n is the exponent for the base x. Note how the index of the root (n) becomes the denominator of the fraction m/n. So for example if we had n = 3, then we'd be dealing with a cube root.

For part a), we have x = 7, m = 1 and n = 5 to get

[tex]\sqrt[n]{x^m}=x^{m/n}\\\\\sqrt[5]{7^1}=7^{1/5}\\\\\sqrt[5]{7}=7^{1/5}\\\\[/tex]

-----------------

Part b) is the same idea

We would find that

[tex]\sqrt[n]{x^m}=x^{m/n}\\\\\sqrt[7]{7^1}=7^{1/7}\\\\\sqrt[7]{7}=7^{1/7}\\\\[/tex]

Then apply the reciprocal to both sides. This is the same as raising both sides to the exponent -1

[tex]\sqrt[7]{7}=7^{1/7}\\\\\left(\sqrt[7]{7}\right)^{-1}=\left(7^{1/7}\right)^{-1}\\\\\frac{1}{\sqrt[7]{7}}=7^{1/7*(-1)}\\\\\frac{1}{\sqrt[7]{7}}=7^{-1/7}\\\\[/tex]

You could also use the rule that x^(-y) = 1/(x^y) when dealing with negative exponents.

In the second to last step shown above, I used the rule (x^y)^z = x^(y*z) on the right hand side.

Answer:

Step-by-step explanation:

Part A

The units on 9500 must be miles. So if x is time, then 55 must be the rate at which she travels ie 55 miles per hour. So the answer must be A.

Part B

The trip began when the time was zero. Therefore x is zero. What remains is the mileage on the odometer when x = 0.  The answer must be 1950.

Answer:

168.168 square inches

Step-by-step explanation:

Given data

From the question, we can deduce that the side of the square is 28in

Hence the area of the square is

Area= 28^2

Area= 784 square inches

Also, the diameter of the circle is 28 in

The radius = 14 in

Area of circle= πr^2

Area= 3.142*14^2

Area= 3.142* 196

Area= 615.832 square inches

Therefore the area of the shaded region is

= Area of Square - Area of Circle

= 784-615.832

=168.168 square inches

Answer:

Step-by-step explanation:

Surface area = 4*lateral faces + 2*bases

I don't understand the question. What do I have to do? Are those points? if yes, what does that equal sign even mean?

Answer:

I think so is it is not a right triangle or a specific type of triangle

Step-by-step explanation:

Answer:

(4,3) is 2

(-2,5) is 1

(-1,-1) is 3

(3,-5) is 4

Step-by-step explanation:

Answer:

put the green dot 4 marks to the right and 3 marks up

put the purple dot 2 marks to the left and 5 marks up

put the blue dot 1 mark to the left and 1 mark down

put the pink dot 3 marks to the right and 5 marks down

Step-by-step explanation:

its a pretty self explanitory question. just put the colord dots on their matching coordinates

Answer: neither refer to image

Answer:

120 and can I have brainliest

Step-by-step explanation:

Answer:

[tex]CD = 4.4ft[/tex]

Step-by-step explanation:

Given

[tex]DE = 12[/tex]

[tex]\angle C = 70^\circ[/tex]

Required

Find CD

This question is represented with the attached triangle

To solve CD, we make use of tan formula.

[tex]tan(70) = \frac{DE}{CD}[/tex]

Substitute 12 for DE

[tex]tan(70) = \frac{12}{CD}[/tex]

Make CD the subject

[tex]CD = \frac{12}{tan(70)}[/tex]

[tex]CD = \frac{12}{2.7475}[/tex]

[tex]CD = 4.4ft[/tex] --- approximated

Answer:

12.8

Step-by-step explanation:

Answer:

150 scores

Step-by-step explanation:

The computation of the score did she get is shown below:

Since there is 18 test presented

And if the test is done on correct manner so 10 points should be awarded

Now since fifth-sixth would be done correctly

So,

= 18 × 5 ÷ 6 × 10

= 150 scores

Answer:

−22

Answer:345

Step-by-step explanation:

Answer:

2x+5

Step-by-step explanation:

Okay so lets first factor 2x^2+15x+25

2*25=50

10+5=15

10*5=15

(x+10/2)(x+5/2)

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

we know that the width is x+5 so that means the length has to be 2x+5

Answer:

Part A: d ≥ 500

Part B: d must be over or equal to 500 but can go infinity at 500+

Step-by-step explanation:

Part A:

≥ stands for "at least" and d has to be "at least" 500,

hence d ≥ 500

Answer:

2

Step-by-step explanation:

17 - 5(3) (Plug in)

= 17-15 (Multiply)

= 2 (Simplify)

Step-by-step explanation:

Area of the square:

a^2: 4^2=16in^2

Area of the circle:

πr^2: π(4.5)^2= 63.6

Area of white part:

63.6 - 16 = 47.6

Probability of landing on square:

16/63.6 = 0.25

Probability of landing on white part:

63.6/16 = 3.975
