What is the slope of the line that passes through the points listed in the table?

x | y
5 | 8
6 | 13


A. -3
B. 3
C. 5
D. 7

Answers

Answer: -3

Step-by-step explanation:

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Jerry is 5 years less than half of Mary's age. The sum of their ages is 22. How old is each person?

Answers

Answer:

Mary= 18

Jerry = 4

Step-by-step explanation:

Half of mary's age is 9, minus 5 =4.

18+4=22

Answer:

Equation 1: m/2 - 5 = j

Equation 2: m + j = 22

Mary's age: 18

Jerry's age: 4

Step-by-step explanation:

m/2 - 5 = j

18/2 - 5 = j

9 - 5 = 4

m + j = 22

18 + 4 = 22

22 = 22

Answer:

87.5 ml tube of toothpaste slightly offers the better value of money.

Step-by-step explanation:

In order to know the better value of money, we need to find the volume of each toothpaste for 1p.

For first tube of toothpaste:

87.5 ml costs 49p

Therefore, for 1 p = 87.5/49 = 1.78571429 = 1.8 ml

For second tube of toothpaste:

125 ml costs 72 p

Therefore, for 1 p = 125/72 = 1.73611111 = 1.7 ml

Since, 1.8 ml > 1.7 ml

So, 87.5 ml tube of toothpaste slightly offers the better value of money.

Line m intersects lines r,s,t, and w. Based on the given angles, which statement must be true?

Answers

OPTIONS:

A. Lines r and s are parallel.

B. Lines r and t are parallel.

C. Lines r and w are parallel.

D. Lines s and w are parallel

*See diagram in the attachment below

Answer:

B. Lines r and t are parallel.

Step-by-step explanation:

105° lies outside of line r when line m cuts across line r. The adjacent angle that forms a linear pair with 105° would be:

180° - 105° = 75°

Thus, the angle formed outside line t when line m cuts across line t is also equal to 75°.

75° at line t is a matching corner with the 75° at line r. Therefore, lines r and t are parallel.

The volume of a cylinder is 32.25 cubic inches. If a cone has the same height and radius as the cylinder, what is its volume?
A. 8.06 cu. in.
B. 10.75 cu. in.
C. 21.5 cu. in.
D. 32.25 cu. in.

Answers

Answer:

B.   10.75 cu. in.

Step-by-step explanation:

Vol. of cylinder = π[tex]r^{2}[/tex]h = 32.25

If the cone has the same radius and height,

then the vol. of the cone = π[tex]r^{2}[/tex]h/3 = 32.25/3 = 10.75 cu. in.

What is the equation that represents the line that passes through the points (9, -2) and (12, -5)?

Hi there!

[tex]\large\boxed{y = -x + 7}[/tex]

To begin, we must use the slope formula to calculate the slope of the line:

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

Plug in the coordinates:

[tex]m = \frac{-5-(-2)}{12-9}[/tex]

Simplify:

[tex]m = \frac{-3}{3} =-1[/tex]

Recall that the equation for a line in point-slope form is:

y - y1 = m(x - x1)

Plug in coordinates into the equation along with the slope:

y - (-2) = -1(x - 9)

Simplify:

y + 2 = -x + 9

y = -x + 7

What is a logarithm?

The logarithm is exponentiation's opposite function in mathematics.

This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.

If 8 cents=10 pebbles then do 205 divided by 10 which is 20.5 . So, 8×20.5=164 dollars.

(8×20.5=164) 8 cents=10 (10×20.5=205)

164 dollars=205

Therefore,the answer is 164 dollars.
