  -9 and +8 have a sum of -1 and a product of -72

Step-by-step explanation:

There are no two integers with the same sign that have a product of +72 and a sum of -1.

The two integers -9 and +8 have a product of -72 and a sum of -1.

Answer:

it would be D

So, when they say quantities that combine to make 0, that means you have to lose, and then gain the same amount back.

If you look at all the other choices, they either keep on gaining or they don't gain the same amount they lost

Think about it as breaking even.  You aren't actually gaining anything if you are gaining back the exact same amount you lost.

Answer:

The slope is 2 and the equation would be m(x)=2x+4.

Step-by-step explanation:

y/x so by looking at the graph you would go up to units and over l unit, therefore giving you the slope of 2.

Answer:

x=22.5

Step-by-step explanation:

Make a ratio

The names of the triangle help with this.

AB is similar to FG, and AC is similar to FH (the missing side)

6/15 = 9/x

cross multiply

6x=135

divide both sides by 6

x=22.5

Answer:

X=22.5

Step-by-step explanation:

6/9=15/x

135=6x

22.5=X

Answer:

Height = 2545.45cm

Step-by-step explanation:

Answer:

  3.14

Step-by-step explanation:

The formula for the area of a circle is ...

  A = πr²

The constant of proportionality is the constant in this equation: π. To two decimal places, the value of π is 3.14.

The constant of proportionality is about 3.14.

Answer:

7. 56

8. 117

Step-by-step explanation:

7.

Add the lengths of the sides. Each square on the grid has side 2 units.

9 + 4 + 4 + 8 + 11 + 3 + 2 + 15 = 56

8.

Find the lengths of the bases and the height of the trapezoid. Each square on the grid is 2 units.

Area of trapezoid = (1/2)(b1 + b2)h

area = (1/2)(15 + 11)(9) = 117

Answer:

-3: C

-2: F

-1: A

6: D

Step-by-step explanation:

-3+2 = -1

-1 = (-1)^3

-3: C

-2+1 = 0

0 = 0^3

-2: F

-1+2 = 1

1 = 1^3

-1: A

6 + 2 = 8

Answer:

7 hours

Explanation:

Divide 5 and 335 then multiply by 469

because 5 / 339 will be time for one mile and then multiply by 469 will be number of hours for 469 miles

5 / 339 × 469 =7 hours

Answer:

Step-by-step explanation:

Some useful relations are ...

  A triangle inscribed in a semicircle is a right triangle.

  Acute angles in a right triangle are complementary.

  An inscribed angle is half the measure of the arc it intercepts.

  The sum of arcs around a circle is 360°; 180° around a semicircle.

__

1. Arc DF is twice the marked inscribed angle, so is 126°. Arc FE is supplementary to that, so is ...

  arc FE = 180° -126°

  arc FE = 54°

Alternate solution: arc FE is twice angle D, which is the complement of 63°.

  2(90° -63°) = 2(27°) = 54° = arc FE

__

2. Arc GJ = 360°-68° -31° -115° = 146°

  angle GHJ = angle GIJ = 146°/2 = 73°

__

3. arc UT = 2(90° -43°) = 94°

  9x -14 = 94

  9x = 108 . . . . . add 14

  x = 12 . . . . . . . . divide by 9

Answer:

the length is represented by (6x + 10y) and the width by (6x - 10y)

Step-by-step explanation:

36x^2 - 100y^2 is the difference of two squares, so we need only factor this expression to obtain the length and width.

Recall that a similar difference, a^2 - b^2, comes out to (a - b)(a + b).

Thus, (36x)^2 = (100y)^2 = (6x - 10y)(6x + 10y).

Let's assume that the greater measurement, the length, is represented by (6x + 10y) and the width by (6x - 10y)

Answer:

a. 0.0018 = 0.18% probability that your car has a worse highway gas mileage than the Civic

b. 89.06% of cars are likely to have a better city gas mileage than the Continental

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

a. The Honda Civic had a rating of 45 highway MPG. What is the probability that your car has a worse highway gas mileage than the Civic?

For Highway, we have that [tex]\mu = 29.09, \sigma = 5.46[/tex]

This probability is the pvalue of Z when X = 45. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{45 - 29.09}{5.46}[/tex]

[tex]Z = 2.91[/tex]

[tex]Z = 2.91[/tex] has a pvalue of 0.9982

1 - 0.9982 = 0.0018

0.0018 = 0.18% probability that your car has a worse highway gas mileage than the Civic.

b. The Lincoln Continental had a rating of 17 city MPG. What percent of cars are likely to have a better city gas mileage than the Continental?

City means that [tex]\mu = 22.37, \sigma = 4.37[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 17. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{17 - 22.37}{4.37}[/tex]

[tex]Z = -1.23[/tex]

[tex]Z = -1.23[/tex] has a pvalue of 0.1094

1 - 0.1094 = 0.8906

0.8906 = 89.06% of cars are likely to have a better city gas mileage than the Continental

Answer:

Step-by-step explanation:

If x is an odd integer, the next greater odd integer is x+2. The product is said to be 63, so the equation is ...

  x(x +2) = 63

__

The equation can be rewritten as ...

  (x +1)² = 64

  x = -1 ±√64 = -1 ±8

The positive solution is x=7, so the positive set of integers is {7, 9}.

The negative solution is x=-9, so the negative set of integers is {-9, -7}.

  B.  301.6 ft

Step-by-step explanation:

The circumference of the circle is given by the formula ...

  C = πd

For a diameter of 96 ft, the circumference of the circle is ...

  C = π(96 ft) ≈ 301.593 ft

The car would travel about 301.6 feet.
