So, option (b) is answer.

Answer:

200 miles

Step-by-step explanation:

one inch = 50 miles, 4 × 50 = 200

Answer:

B) 12

Step-by-step explanation:

These two angles are known as same-side interior angles. These angles add up to 180°. Use this to solve for y:

9y + 7 + 7y - 19 = 180

16y - 12 = 180

16y = 192

y = 12

Answer:

y = - 8/3 x - 11

Step-by-step explanation:

We start by finding the slope of the segment thatjoins the two points using the slope formula:

slope = (y2 - y1) / (x2 - x1)

In our case:

slope = (-3 -5) / (-3 - -6) = -8/3

Now that we have the slope, we use the general expression for a line in slope-intercept form ( y = m x + b), requesting that one of the given points (for example point (-3, -3) )is part of the line as shown below:

y = m x + b

y = - 8/3 x + b

(-3) = - 8/3 (-3) + b

- 3 = 8 + b

b = - 11

Then the equation of the line is:

y = - 8/3 x - 11

Answer:

The calculated value  t = 1.399 < 2.5705 at 0.025 level of significance

Null hypothesis is accepted

The population distribution is approximately normal

Step-by-step explanation:

Step(i):-

Given mean of the Population = 5.0

sample size 'n'= 6

The mean of the sample x=5.4 pounds /square inch

The standard deviation of the sample (S) = 0.7

Level of significance = 0.025

Null Hypothesis : The sample came from population

H₀ : x⁻ = μ

Alternative Hypothesis :H₁ : x⁻ ≠ μ

Step(ii):-

Test statistic

                      [tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]

                     [tex]t = \frac{5.4 -5.0}{\frac{0.7}{\sqrt{6} } }[/tex]

                     t = 1.399

Degrees of freedom = n-1 =6-1 =5

The tabulated value

                  t = 2.5705

The calculated value  t = 1.399 < 2.5705 at 0.025 level of significance

Null hypothesis is accepted

The population distribution is approximately normal

Answer:

slope = -5

Step-by-step explanation:

not sure what 1 OO us when we o 5 is? but in y = mx + b, m = slope and b = y int so slope is -5 (y int is 0)

Answer:

450

Step-by-step explanation:

[tex] \frac{28}{100} = \frac{126}{x} \\ \frac{7}{25} = \frac{126}{x} \\ 7x = 126 \times 25 \\ x = \frac{126 \times 25}{7} = 450[/tex]

or

[tex]126 \div 0.28 = 450[/tex]

for estimating round both the price of shoes and the percentage to round numbers

97.65 is close to 100, so use 100 for the price of shoes

68% is close to 70 so use 70%

then multiply 100 by 70 %,

100 *70% = 70 dollars

so Isaac would pay around 70 dollars

Answer:

Issac has to pay 68% and 68% as a decimal is .68 So to solve this you would multiply 97.65 x .68 = 66.40 So Isaac will pay $66.40 dollars. If you want to go  even further his family would pay 31.25$ of the total cost. Hope this helps you

Answer:

A: Yes, As more gallons are used the longer the shower is

B: 5 minutes, 20 minutes

C: (30,10), someone who uses 30 gallons of water will be in the shower for 10 minutes

D: I'm going to assume that your teacher wants you to find the slope in which I will use the slope formula and the points (0,0) and (30,10)

(10-0)/(30-0)=1/3=.33333 which means that for every gallon of water used you will be in the shower for .33333 minutes longer

Step-by-step explanation:

A: Yes, As more gallons are used the longer the shower is

B: 5 minutes, 20 minutes

C: (30,10), someone who uses 30 gallons of water will be in the shower for 10 minutes

D: I'm going to assume that your teacher wants you to find the slope in which I will use the slope formula and the points (0,0) and (30,10)

(10-0)/(30-0)=1/3=.33333 which means that for every gallon of water used you will be in the shower for .33333 minutes longer

Answer:

The slope equals -⁴/3

Step-by-step explanation:

Slope of the line passing through the origin (0, 0) and (-9, 12):

Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 0}{-9 - 0} = \frac{12}{-9} = -\frac{4}{3} [/tex]

Slope (m) = -⁴/3

Step-by-step explanation:

416/52 = 8

Answer:

4. 50.19°

5. 25.19°

Step-by-step explanation:

4. Reference angle = x°

Opposite = 6 units

Adjacent = 5 units

Thus,

[tex] tan(x) = \frac{6}{5} [/tex]

[tex] tan(x) = 1.2 [/tex]

[tex] x = tan^{-1}(1.2) [/tex]

[tex] x = 50.19 [/tex] (nearest hundredth)

5. Reference angle = x°

Opposite = 48 - 5.2 = 42.8 ft

Adjacent = 91 ft

Thus,

[tex] tan(x) = \frac{42.8}{91} [/tex]

[tex] tan(x) = 0.47032967 [/tex]

[tex] x = tan^{-1}(0.47032967) [/tex]

[tex] x = 25.19 [/tex] (nearest hundredth)b
