Answer:

Kayla drove 45miles

Answer: She went 3/4 miles in a minute and 45 miles in an hour

Step-by-step explanation:

15 miles in 20 minutes so 45 miles in 1 hour or 60 minutes

Since 45 miles in 60 minutes, 3/4 miles in a minute

9514 1404 393

Answer:

  $400

Step-by-step explanation:

The word "per" in math often means "divided by". To find price per square foot, find price divided by square feet.

  $700,000/(1750 ft²) = $400 /ft²

The price per square foot of House 4 was $400.

Step-by-step explanation:

7x-21 = 5x +15

7x-5x = 15 + 21

2x = 36

x = 36/2

x = 18

Answer:

x=18

Step-by-step explanation:

Distribute 7 through the parentheses

7x-21=5(x+3)

Move the variable to the left -hand side and change its sign

7x-21-5x=15

Collect like terms

2x=15+21

divide both sides of the equation by 2

x=18

Answer:

8 feet

Step-by-step explanation:

.................... ............ . ...

Answer:

8 ft

Step-by-step explanation:

Since 2 angles are given as congruent, the opposite sides are congruent.

The opposite sides of the congruent angles are 8 ft and L, so L = 8 ft.

Answer:

a)  Z Test(n>30)

b)  [tex]t=2.028[/tex]

Step-by-step explanation:

Average [tex]A=3400[/tex]

Mean [tex]\=x=3200[/tex]

Sample size [tex]n=36[/tex]

Standard deviation [tex]\sigma=600mg[/tex]

Generally using the Z Test(n>30)

Generally the equation for Standard Error S.E is mathematically given by

[tex]S.E=\frac{600}{\sqrt{36}}[/tex]}

[tex]S.E=100[/tex]

Generally the equation for Z test is mathematically given by

[tex]Z=\frac{\=x-A}{\sigma\sqrt{n}}[/tex]

[tex]Z=\frac{3200-3400}{600\sqrt{36}}[/tex]

[tex]Z=-2[/tex]

From table

[tex]T critical= (Z,df)[/tex]

Where

[tex]df=n-1[/tex]

[tex]df=35[/tex]

Therefore

[tex]t=2.028[/tex]

Answer:

Step-by-step explanation:

D ANSWER D

Answer:

d

Step-by-step explanation:

Answer:

Step-by-step explanation:

Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

If, sinθ = -[tex]\frac{1}{2}[/tex] and π < θ < [tex]\frac{3\pi }{2}[/tex]

Since, sinθ is negative, angle θ will be in IIIrd quadrant.

And the measure of angle θ will be (180° + 30°)

θ = 210°

It's necessary to remember that tangent and cotangent of angle θ in quadrant III are positive.

Therefore, cos(210°) = [tex]-\frac{\sqrt{3} }{2}[/tex]

tan(210°) = [tex]\frac{1}{\sqrt{3} }[/tex]

csc(210°) = [tex]-\frac{1}{2}[/tex]

sec(210°) = [tex]-\frac{2}{\sqrt{3} }[/tex]

cot(210°) = √3

Answer:

Using absolute change, Clyde took 6.5 less months to take his first steps than Jacob.

Using relative change, it took Clyde 38.24% less time than Jacob to take his first steps.

Step-by-step explanation:

Absolute change:

A number, that is, the difference between two measures.

Jacob: 17 months

Clyde: 10.5 months.

17 - 10.5 = 6.5

Using absolute change, Clyde took 6.5 less months to take his first steps than Jacob.

Relative change:

Absolute change multiplied by 100% and divided by the reference value. So

6.5*100%/17 = 38.24%

Using relative change, it took Clyde 38.24% less time than Jacob to take his first steps.

Answer:

x = 22 degree

Step-by-step explanation:

40 + 5x + 30 = 180 degree (being linear pair)

5x + 70 = 180

5x = 180 - 70

x = 110/5

x = 22 degree

Answer:

[tex] \blue{y = \dfrac{C + 2k}{2}} [/tex]

Step-by-step explanation:

[tex] C = 2(y - k) [/tex]

[tex] C = 2y - 2k [/tex]

[tex] C + 2k = 2y [/tex]

[tex] \dfrac{C + 2k}{2} = y [/tex]

[tex] y = \dfrac{C + 2k}{2} [/tex]

Answer:

b.  [tex]\frac{7+\sqrt{61} }{6} ,\frac{7-\sqrt{61} }{6}[/tex]

Step-by-step explanation:

[tex]3x^{2} -1=7x[/tex]

Quadratic equations are suppose to be written as: [tex]ax^2+bx+c=0[/tex]

so the new quadratic equation for this problem will be: [tex]3x^{2} -1-7x=0[/tex]

Now rearrange the terms: [tex]3x^{2} -7x-1=0[/tex]

Then use the Quadratic Formula to Solve for the Quadratic Equation

Quadratic Formula = [tex]x=\frac{-b±}{} \frac{\sqrt{b^2-4ac} }{2a}[/tex]

Note: Ignore the A in the quadratic formula

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

[tex]3x^{2} -7x-1=0[/tex]

a = 3

b = -7

c = -1

[tex]x=-(-7)±\frac{\sqrt{(-7)^2-4(3)(-1)} }{2(3)}[/tex]

Evaluate The Exponent

[tex]x=\frac{7±\sqrt{(49)-4(3)(-1)} }{2(3)}[/tex]

Multiply The Numbers

[tex]x=\frac{7±\sqrt{49+12} }{2(3)}[/tex]

Add The Numbers

[tex]x=\frac{7±\sqrt{61} }{2(3)}[/tex]

Multiply The Numbers

[tex]x=\frac{7±\sqrt{61} }{6}[/tex]

Answer:

a) 9000 ft-lb

b) 9000 ft-lb

Step-by-step explanation:

Equation for the work:

The equation for the work done is given by:

[tex]W = Fd[/tex]

In which F is the force needed and d is the distance. The time does not interfere on the work.

A 300-lb gorilla climbs a tree to a height of 30 ft

This means that [tex]F = 300, h = 30[/tex]

Thus

[tex]W = Fd = 300(30) = 9000[/tex]

The work done in both cases is of 9000 ft-lb, as the work is not a function of time.

Answer:

Mean before the rent changes = $935.8

Mean after the rent changes = $970.8

Step-by-step explanation:

Mean = sum of all data values / number of data values in a given data set

✔️Data set consisting of the rents of 5 tenants: 879 , 920 , 940 , 950 , 990

Mean before the rent changes = (879 + 920 + 940 + 950 + 990)/5 = 4,679/5 = 935.8

Mean before the rent changes = $935.8

✔️If one of the tenants rent changes from $940 to $1,115, the new data set would be:

879 , 920 , 1,115 , 950 , 990

Mean after the rent changes = (879 + 920 + 1,115 + 950 + 990)/5 = 4,854/5 = 970.8

Mean after the rent changes = $970.8

Answer:

Step-by-step explanation:

Answer:

c. The data are continuous because the data can take on any value in an interval.

Step-by-step explanation:

Discrete data are those which can take up only specific values. Discrete data values may include the number of children in a particular school, the number of visitors received per day. All this values are specific and cannot just take up any number one f values within an interval. Continous data on the other hand can take up any number of data values between an interval. Continous data types are usually height temperature, length(distance data). There can be infinite number of possible data within interval values.

Answer:

1. 8

2 . 11

[tex]3 . \sqrt{128} \ or \ 8 \sqrt2[/tex]

Step-by-step explanation:

[tex]Distance = \sqrt{(x_2 -x_1)^2 + (y_2 - y_1)^2 }[/tex]

1 . ( 5 , - 2 ) and ( 5 , 6 )

  [tex]Distance = \sqrt{(5 -5)^2 + ( 6-(-2))^2} = \sqrt{ 0 + 8^2 } = \sqrt{64} = 8[/tex]

2 . ( 8 , 6 ) and ( - 3 , 6 )

  [tex]Distance = \sqrt{( -3 -8)^2 + ( 6 - 6)^2 } = \sqrt{ (-11)^2 + 0 } = \sqrt { 121 } = 11[/tex]

3. ( 5 , - 2 ) and ( -3 , 6 )

  [tex]Distance = \sqrt{(-3 - 5)^2 + ( 6 --2)^2} = \sqrt{(-8)^2 + ( 8)^2} = \sqrt{ 64 + 64 } = \sqrt{128}[/tex]

          [tex][ \ \sqrt{128} = \sqrt{ 2 \times 64} = \sqrt{ 2 \times 8^2 } = 8 \sqrt{2} \ ][/tex]

Answer:

x² - x - 2

Step-by-step explanation:

Since the curve cuts the x-axis at x = -1 and 2. The factors will be x+1 and x-2

Taking the product of the factors

f(x) = (x+1)(x-2)

f(x) = x² - 2x + x - 2

f(x) = x² - x - 2

Hence the required function is x² - x - 2
