Tighe starts at sea level and hikes up to an elevation of 70 ft. Then he descends(walks down) in the direction of his starting point to an elevation of 30 ft. Tighe says the integer −30 represents his elevation at this point. Is Tighe correct? Explain your reasoning.

Answer:

-2

Step-by-step explanation:

By definition the slope is value m in the equation y=mx+b. Here, m=-2 and b=0.

Answer:

The slope is -2

Step-by-step explanation:

Answers:

1. Miles driven

2. Price of rental

3. y = 2x + 6

(The fixed/initial cost is b, the y-intercept. The 2 is the price per mile and the x is the miles driven.)

4. y = 3x

(Since there's no initial cost, the equation is simply 3 times x)

5. A

6. The slope for Laguna is 2. This is the price per mile.

7. The slope for Salvatori is 3. This is the price per mile.

8. The y-intercept for Laguna is 6. This is the initial, fixed cost of renting a truck.

9. The y-intercept for Salvatori is 0. This means there is no initial cost.

10. The point of intersection is the amount of miles driven at which both companies are the same price. If Jenny drives 6 miles, she'll pay $18 either way.

Answer:

27

Step-by-step explanation:

You add 63 and 90 (90 being the right angle) and then subtract that from 180 which is the sum of all three angles and you get 27.

Answer:

50 to 15 min 30 sec

15 min 30 sec is actually 930 seconds

3600 sec in hour

-- not finished, working on it

Step-by-step explanation:

360/45 = x/60

45n = 60

n = 60/45

n = 1.333 or 1 and 1/3

multiply the numerator by the same amount as the denominator

360 multiplied by 1.333 = 480

480parts/hour

Answer:

A. 48

B. 24

C. C

Step-by-step explanation:

To divide up whole numbers by fractions, you simply need to just multiply the whole number by the reciprocal of the fraction. in other words, flip the fraction.

Ex.

12 ÷ 1/4

=

12 x 4

Ex. 2

12 ÷ 1/2

=

12 x 2

Answer:

answer: -5

Answer:

B. 12/33

Step-by-step explanation:

Since there are 12 bluebonnets and 30 seeds in total, the ratio will be 12:33.

Answer:

Step-by-step explanation:

First you have to see how many seeds will be in total. There are 33 seeds in total and there are 12 bluebonnet seeds. I believe it would be 12/33

The scatter plots are solved and the graph C and graph D are true

In a scatter plot, dots are used to represent the values of two separate numerical variables. The values of each data point are represented by the position of each dot on the horizontal and vertical axes. Use scatter plots to see how different variables are related to one another.

Data patterns or trends may be shown using scatter plots, which can also be used to spot any relationships between two variables. The strength and direction of the association between the two variables may be inferred from the scatter plot's shape and orientation.

Given the data ,

Let A, B, C, and D represent the scatter plots.

So, a negative association in a scatter plot describes a relationship between two variables in which a rise in one measure is linked to a drop in the other. This implies that the tendency is for the other variable to decrease as the first variable rises. A trend line or regression line with a falling slope is used to represent it.

Moreover, a positive association in a scatter plot denotes a link between two variables where a rise in one is correlated with a rise in the other. An upward-sloping trend line or regression line is used to represent it.

So , the scatter plots A and B are False

The non-linear and lack of trend charts are therefore accurate.

Answer:

x = 31º

Step-by-step explanation:

The verticle angle at the bottom left is 33º

The supplementary angle on the bottom right is 180 - 98 = 82

Sum of the angles in a triangle is 180

(34 + x) + 33 + 82 = 180

Combine like terms

x + 149 = 180

Subtract 149 from both sides

x = 31º

Answer:

x = 31º

The verticle angle at the bottom left is 33º

The supplementary angle on the bottom right is 180 - 98 = 82

Sum of the angles in a triangle is 180

(34 + x) + 33 + 82 = 180

Combine like terms

x + 149 = 180

Subtract 149 from both sides

x = 31º

5x=11-16

5x=-5

x=-1

Answer:

x = -1

Step-by-step explanation:

2(2.5x + 8) = 11

Divide both sides by

2.5x + 8 = 5.5

Subtract 8 from both sides

2.5x = -2.5

Divide both sides by 2.5

x = -1

It's really simple..

look

5a2-60a+180

5 (a2 - 12a + 36)

5 (a2 - 6a - 6a +36)

5 ( a(a - 6) -6( a- 6)

5 (a-6)(a-6)

5(a-6)^2

s2 - 256

s2 - 16^2

(s+16) (s-16)

Answer:

Step-by-step explanation:

a² - 12a + 36 = a² + 2*a *6 + 6²

Compare with (x -y)² = x²- 2ab + y²

                      = (a - 6)²

5a² - 60a + 180 = 5 *a² - 5 * 12 * a + 5 * 36

                        =  5 (a² - 12a + 36)

                        =  5 (a - 6)²

256 = 16 * 16 = 16²

a² - b² = (a + b)(a - b)

s² - 256 = s² - 16²

             = (s + 16) (s - 16)

49q² + 42qr + 9r² = 7²q² + 2 * (7q)  * 3r + 3²r²

                              = (7q)² + 2 *7q * 3r  +(3r)²

                              = (7q + 3r)²
