Answer:

225sqft with 1in -> 5ft  = 9sqin

147sqft with 1in -> 7ft = 3sqin

256sqft with 1in ->8ft = 4sqin

128sqft with 1in -> 4ft = 8sqin

Step-by-step explanation:

To change from feet to inches, you just divide by the scaling factor (5, 7, 8, or 4) in this problem.  But because it is square feet to square inches, you must divide by the square of the scaling factor:

5*5 = 25

7*7 = 49

8*8 = 64

4*4 = 16

So:

225/25=9

147/49 = 3

256/64 = 4

128/16 = 8

Answer:

The answer is (h).

Step-by-step explanation:

When y = 2^x is shifted 4 units left, the x shifts 4 units to the left and x becomes (x+4). When the graph is shifted to units down, y has to be subtracted by 2.

The function becomes

y = 2^(x+4) -2.

Finally, you shift -2 to the same side as y.

This becomes

y+2 = 2^(x+4) which is (h)

Answer:

  38.63 m

Step-by-step explanation:

The definition of the perimeter tells you that you need to find the lengths of each of the edges of the figure.

The diagonal edge at left is the hypotenuse of a right triangle with legs 4 and 6. They Pythagorean theorem tells you that length is ...

  d = √(4² +6²) = √52 ≈ 7.21 . . . meters

The straight line across the top is marked 9 meters.

The semicircle length is half the circumference of a circle with diameter 6 m. That semicircle length is ...

  semicircle length = (1/2)πd = (1/2)(3.14)(6 m) = 9.42 m

The straight bottom edge of the figure is 4+9 = 13 m.

Then the sum of lengths around the figure is ...

  7.21 m + 9 m + 9.42 m + 13 m = 38.63 m

The perimeter of the figure rounded to 2 decimal places is 38.63 meters.

Final Answer:

Corresponding Angles Theorum; ∠AGF and ∠EHD are congruent

Answer:

x = 43

Step-by-step explanation:

The two angles add to 93

x+ 50 = 93

Subtract 50 from each side

x+50-50 = 93-50

x = 43

Answer:

x = 43 °

Step-by-step explanation:

sum of two angles is equal to 93°,

50 ° + x = 93 °

Subtract 50° from each side

50° - 50° + x = 93° - 50°

x = 43°

Answer:

Jose's father weighs 70 kilograms.

Step-by-step explanation:

Given that Jose weighs 25 kg, while his father is 5 kg less than 3 times Jose's weight, to determine what is the weight of Jose father the following calculation must be performed:

Jose = 25

Father = 3J - 5

3 x 25 - 5 = Father

75 - 5 = X

70 = X

Therefore, Jose's father weighs 70 kilograms.

y = 111/83

z = 452/83

Answer:

Distance = 660 meters

Step-by-step explanation:

Given the following data;

Radius, r = 21 m

Number of revolutions = 5 times

To find the distance covered;

The distance covered in one revolution is given by the circumference of a circle.

Mathematically, circumfeence of a circle is equal to;

C = 2πr

Substituting into the formula, we have;

C = 2 * 22/7 * 21

C = 44 * 3

C = 132 meters

Next, we find the distance covered;

Distance = Circumference * Number of revolutions

Distance = 132 * 5

Distance = 660 meters

Answer: 16%

Step-by-step explanation:

Notice that 154 minutes is one standard deviation greater than the mean. Based on the empirical rule 68% of the finishing times are within one standard deviation of the mean, so 100%-68%=32% of the finishing times are outside of one standard deviation from the mean one either direction. Since the normal distribution is symmetric , half of the 32% will be less than the mean and half will be greater, so 16% of the finishing times are greater than the one standard deviation more than the mean.

The probability that race participant had a finishing time of greater than 154 minutes is 16%

The empirical rule states that for a normal distribution, 68% are within one standard deviation from the mean, 95% are within two standard deviation from the mean and 99.7% are are within three standard deviation from the mean.

Given that mean (μ) = 143, standard deviation σ = 11

The probability that race participant had a finishing time of greater than 154 minutes is 16% [(100% - 68%)/2]

[tex]Area= 37193\ cm^2[/tex]

Step-by-step explanation:

Given

[tex]q = 590cm[/tex]

[tex]r = 310cm[/tex]

[tex]\angle P =24^o[/tex]

Required

The area of [tex]\triangle PQR[/tex]

This is calculated as:

[tex]Area= \frac{1}{2} * qr* \sin(P)[/tex]

So, we have:

[tex]Area= \frac{1}{2} * 590cm * 310cm* \sin(24^o)[/tex]

[tex]Area= \frac{1}{2} * 590cm * 310cm* 0.4067[/tex]

Answer:

155 + [tex]x^{3}[/tex] + 14

Step-by-step explanation:

The variable x would represent the number/value we don't know, and in this case, we don't know what number is raised to the third power. This being said, x would represent that number.

The question, although worded a bit confusingly, asks to add 155, the number (x) to the exponent of 3, and 14. Mathematically, this would be 155 + [tex]x^{3}[/tex] + 14.

Answer:

Depends. See below.

Step-by-step explanation:

Let's take 1*-2 for example. If we multiplied 1 with -2, the resulting product will be negative since it's -2. Now if we did -1*-2, then the resulting product will be positive since it's 2.

Answer:

The probability of selecting 2 Democrats and 2 Republicans is 29.36%.

Step-by-step explanation:

Given that a city council consists of 7 democrats and 7 republicans, to determine, if a committee of 4 people is selected, the probability of selecting 2 Democrats and 2 Republicans must be performed the following calculation:

7/14 x 6/13 x 7/12 x 6/11 = X

0.5 x 0.46 x 0.58 x 0.54 = X

0.0734 = X

0.0734 x 100 = 7.34 x 4 = 29.36

Therefore, the probability of selecting 2 Democrats and 2 Republicans is 29.36%.

Answer:

length = 12

width = 15

Step-by-step explanation:

if you foil (x+7)(x+10) you get:

x²+17x-110 = 0

the factors are:

(x+22)(x-5) = 0

x = -22 and 5

we can dismiss the negative as irrelevant for a measure; therefore, x = 5

length = 5+7, or 12

width = 5+10, or 15

Answer:

A = $5,984.74

A = P + I where

P (principal) = $5,000.00

I (interest) = $984.74

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 3/100

r = 0.03 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 5,000.00(1 + 0.03/12)(12)(6)

A = 5,000.00(1 + 0.0025)(72)

A = $5,984.74

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $5,000.00 at a rate of 3% per year compounded 12 times per year over 6 years is $5,984.74.

Answer:

x=8                     x=-2

Step-by-step explanation:

|x-3| -10=-5

Add 10 to each side

|x-3| -10+10=-5+10

|x-3| =5

Now separate into two equations , one positive and one negative

x-3 = 5           x-3 = -5

Add 3 to each side

x-3+3 = 5+3    x-3+3 = -5 +3

x=8                     x=-2

Answer:

x = ± 8

Step-by-step explanation:

|x - 3| - 10 = - 5

|x - 3| - 10 + 10 = - 5 + 10

|x - 3| = 5

x - 3 = 5      

x - 3 + 3 = 5 + 3

x + 3 = - 5

x + 3 - 3 = - 5 - 3

x = - 8

Answer:

There is no significant evidence to support the claim that an association between seed density and lawn quality exists.

Step-by-step explanation:

Given the data :

Seed Density Lawn Quality

1 30

1 40

2 40

3 40

3 50

3 65

4 50

5 50

Using technology to obtain the correlation Coefficient between seed density and lawn quality, the Coefficient, R = 0.6

H0 : ρ = 0

H1 : ρ ≠ 0

We can then calculate the test statistic :

Test statistic = r / √(1 - r²) / (n - 2)

Test statistic = 0.6 / √(1 - 0.6²) / (8 - 2)

Test statistic = 0.6 / 0.3265986

Test statistic = 1.837

Pvalue from test statistic : = 0.11583

α = 0.01

Pvalue > α ;

We fail to reject the null
