Answer:

The height of the building is of 244.95 feet.

Step-by-step explanation:

We use the Pythagorean Theorem to solve this question.

We have that:

The shadow of 50 feet is one side of the right triangle, while the height h is other side.

The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.

So

[tex]50^2 + h^2 = 250^2[/tex]

[tex]h^2 = \sqrt{250^2 - 50^2}[/tex]

[tex]h = 244.95[/tex]

The height of the building is of 244.95 feet.

Answer:

There is significant evidence that Jane has met the requirement.

Step-by-step explanation:

Given that:

μ = 100

μ > 100

Sample size, n = 16

Sample mean, x = 108

Sample standard deviation, s = 12

Level of significance, α = 0.1

Degree of freedom, df = n - 1 = 16 - 1 = 15

Test statistic

T = (x - μ) / s÷sqrt(n)

Tstatistic = (108 - 100) / 12 ÷ sqrt(16)

Tstatistic = 8 / 3

Tstatistic = 2.6667

Using the pvalue calculator :

Tstatistic at 0.1, df = 15 ;

P-value = 0.008799

Since pvalue < α

We reject the Null

The is no significant evidence to conclude that Jane has exceeded an average of more than $100

Answer:

The Highest common factor of 120,140,180 is  ( HCF) = 20

Step-by-step explanation:

Explanation:-

Given numbers  120,140,180

120 = 60 × 2

     = 30 × 2× 2

     = 15 × 2×2×2

    = 5×3× 2×2×2

140 =  70 × 2

      = 10 × 7× 2

      = 5× 2× 7× 2

180 = 90 × 2

      = 30×3×2

     = 5 × 6 × 3× 2

    = 5 × 2× 3× 2 × 3

The Highest common factor of 120,140,180 is   5 ×2×2 = 20

Answer:

36

20 percent * 180 =

(20:100)* 180 =

(20* 180):100 =

3600:100 = 36

Now we have: 20 percent of 180 = 36

Question: What is 20 percent of 180?

Percentage solution with steps:

Step 1: Our output value is 180.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$180=100\%$.

Step 4: Similarly, $x=20\%$.

Step 5: This results in a pair of simple equations:

$180=100\%(1)$.

$x=20\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{180}{x}=\frac{100\%}{20\%}$

Step 7: Again, the reciprocal of both sides gives

Answer:

Decreasing: y, infinity

Constant: y, negative infinity

Step-by-step explanation:

You just had it backwards, the interval for infinity is based on the x-axis not the y-axis. The decreasing portion is moving toward positive infinity on the x-axis because it's moving to the right. The constant is moving to the left so it is negative infinity.

If he still needs 520 to buy the computer in 2 weeks of saving, and 300 to buy the computer in 6 weeks of saving, he saves (520-300)/4, or 55 dollars each week.

So, at week zero, we can find the cost of the computer, which is 520+55+55, or 630 dollars.

The weight of the walnuts alone is 360 pounds

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x + 3 = 4 is an equation.

We have,

Number of craters of walnuts = 10

Weight of 10 craters of walnuts = 370 pounds

Weight of empty crate = 10 pounds

Weight of the 10 walnuts = M

Weight of the 10 walnuts + weight of the crater = 370 pounds

This can be written as an equation:

M + 10 = 370

Subtract 10 on both sides.

M = 370 - 10

M = 360 pounds

Thus,

The weight of the walnuts alone is 360 pounds

Step-by-step explanation:

Multiply 160 by 0.15 to find what 15% of 160.  The answer is 22.5.  Then subtract 22.5 from 160 to find the answer (137.50)

Answer:

$136

Step-by-step explanation:

To solve percent problems, you can use the formula        part            %

                                                                                              -------    =    -----

                                                                                              whole         100

The % would be 15, the whole would be 160, and the part would be x. Cross multiply to get 100x = 2400. Divide 2400 by 100 to get x = 24. Then, subtract 24 from $160 to get $136. The sale price is $136.
