An attic wall is in the shape of a trapezoid. The bases are 12 ft and 25 ft. The area is 185 square feet. What is the height? A = 1/2 h (b + b)

Answers

Answer 1

Answer: b = 2A - B

Step-by-step explanation:

2. A = 2 . 1/2 . h (B + b)

2A = h (B+b)

2A/= h/h . (B+b)

2A/h = B+b

2A - B = B - +b

b = 2A - B

find the diagonal that goes through the 3D shape.

Answers

Answer:

Diagonal = 13 yd

Step-by-step explanation:

The diagonal of the 3D shape can be solved using the extension of the pythagorean theorem, which is given as: d² = a² + b² + c²

Where,

a = 12 yd

b = 3 yd

c = 4 yd

d = diagonal

Plug in the values

d² = 12² + 3² + 4²

d² = 169

d = √169

d = 13 yd

Quadrant 1 Reason being all the positive are housed in quadrant 1

Answer:

D.) Quadrant I

Step-by-step explanation:

The quadrants start from Quadrant I (in the top left) and continue counter-clockwise to Quadrant II, Quadrant III, and Quadrant IV

Quadrant I = (+,+)

Quadrant II = (-,+)

Quadrant III = (-,-)

Quadrant IV = (+,-)

Now in this case, (4,2) is positive in the x value, and positive in the y value - so it belongs in Quadrant I!

The diameter of a spindle in a small motor is supposed to be 5.8 millimeters (mm) with a standard deviation of 0.14 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 12 spindles to determine whether the mean diameter has moved away from the required measurement. Suppose the sample has an average diameter of 5.88 mm. What are the null and alternative hypotheses (H0 = null hypothesis and Ha = alternative hypothesis)?
A. H0: Mean= 5 and Ha: Mean is not equal to 5.
B. H0: Mean = 5 and Ha: Mean <5.
C. H0: Mean < 5 and Ha: Mean > 5.
D. H0: Mean = 5 and Ha: Mean > 5.

Answers

Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.

Step-by-step explanation:

Definitions:

Null hypothesis [tex](H_0)[/tex] is a statement describing population parameters according to the objective of the study. It takes "≤,≥,=" signs.   Alternative hypothesis[tex](H_a)[/tex]  is a statement opposite to the null hypothesis elaborating population parameters according to the objective of the study. It takes ">, <, ≠" signs.

Given: The diameter of a spindle in a small motor is supposed to be 5.8 millimeters.

If the spindle is either too small or too large, the motor will not work properly. so, Mean diameter ≠ 5.8 to work correctly.

i.e. [tex]H_a: \text{Mean}\neq 5.8[/tex]

So, [tex]H_a: \text{Mean =5.8}[/tex]

The required null and alternative hypotheses:

H0: Mean= 5 and Ha: Mean is not equal to 5.

One week Carlos bought 2 packages of dog bones and 4 packages of cat treats for $18.50. Because the finicky cats didn’t like the cat treats, the next week Carlos returned 3 unopened packages of cat treats and bought 2 more packages of dog bones. After being refunded for the cat treats, Carlos only had to pay $1.00 for his purchase. Based on this information, figure out the price of each item. Explain your reasoning.

Answers

Answer:

1 package of dog bones = 4.875

1 package of cat treats = 2.1875

Step-by-step explanation:

you add the $1 to the 18.50 = 19.50 these are the amount of money for 4 bags of dog food. you take away all the dog food(4) from it = 8.75 divide by 4 for the 4 bags of cat food= 2.1875

Drag and drop number tiles into the boxes to show the median, first quartile (Q1) and third quartile (Q3)
of the data on the dot plot.

Answers

Answer:

Median = 5

Q1 = 2

Q3 = 10

Step-by-step explanation:

✔️On the dot plot, each dot represents a data point.

The median is the middle data point which is the 6th data point on the dot plot.

This:

Median = 5 (6th data point)

✔️Q1 is the middle value of the lower set of data points before the median = the 3rd data point

The 3rd data point is 2

Therefore,

Q1 = 2

✔️Q3 is the middle value of the upper set of data points after the median = the 9th data point.

The 9th data point = 10

Therefore,

Q3 = 10

For the plane curve defined by x = 7 cos t, y = 5 cos t, for t in [0, 2π​] the ordered pair that corresponds to t = π/6 is ___

Answers

Answer:

The ordered pair is: [tex](\frac{7\sqrt{3}}{2},\frac{5\sqrt{3}}{2})[/tex]

Step-by-step explanation:

We are given the following plane curve:

[tex]x = 7 \cos{t}[/tex]

[tex]y = 5 \cos{t}[/tex]

Ordered pair for a value of t:

We find (x,y) for these values of t. So, when [tex]t = \frac{\pi}{6}[/tex]

[tex]x = 7 \cos{\frac{\pi}{6}} = 7\frac{\sqrt{3}}{2} = \frac{7\sqrt{3}}{2}[/tex]

[tex]y = 5 \cos{\frac{\pi}{6}} = 5\frac{\sqrt{3}}{2} = \frac{5\sqrt{3}}{2}[/tex]

The ordered pair is: [tex](\frac{7\sqrt{3}}{2},\frac{5\sqrt{3}}{2})[/tex]

The value of the account will be $_____. (Round to the nearest dollar as needed.)

Answers

9514 1404 393

Answer:

  $4047

Step-by-step explanation:

For an interest rate r compounded n times per year for t years, the effective multiplier is ...

  (1 +r/n)^(nt)

The multiplier for the first 5 years is ...

  (1 +0.07/2)^(2·5) = 1.41059876

The multiplier for the last 5 years is ...

  (1 +0.0728/4)^(4·5) = 1.43437218

Then the account value at the end of 10 years is ...

  $2000(1.41059876)(1.43437218) ≈ $4047 . . . . balance after 10 years

Consider the function f(x) = 2 + 2x - 15. What are the x-intercepts of the function?

Answers

Answer:

x=6.5

Step-by-step explanation:

I got the x- intercept as 6.5 because I found the x value when y equals 0.

0=2+2x-15

Next, I added 2+-15 and got -13.

0=2x-13

Then, I added 13 to both sides so that I could have x by itself.

13=2x

Next, I divided 2 on both sides so I could find the value of x.

6.5= x

In conclusion, the x- intercept of f(x)=2+2x-15 is 6.5.

PLS HELP!! Katie earned 15% more this week than last week. This week she earned $225, how much did she earn last week?

Answers

Answer:

$258.75

Step-by-step explanation:

225 * 0.15

Let last weeks pay = x

This week she earned 15% more so she earned 100% + 15% more for 115% total.

Setup an equation:

115% times x = $225

115% as a decimal = 1.15

So the equation is:

1.15x = 225

Solve for x by dividing both sides by 1.15:

X = 225/1.15

X = 195.65

Last week she earned $195.65

On Friday,

1
8
of practice on marching. The remaining practice time was spent playing music.

What fraction of practice time was spent playing music?

Answers

Answer:

[tex]\frac{17}{24}[/tex]

Step-by-step explanation:

First, you have to make all of the fractions have a common denominator. You can find the LCM (least common multiple) of 6 and 8.

6, 12, 18, 24 . . .

8, 16, 24 . . .

Their LCM is 24.

So now, change the fractions:

1         4

----  =  -----

6        24

Remember, whatever you multiply the bottom by to get to 24 is what you multiply the top number by. You have the make sure the fractions are equivalent.

1         3

----  =  -----

8        24

Remember, whatever you multiply the bottom by to get to 24 is what you multiply the top number by. You have the make sure the fractions are equivalent.

So if we have 1 band practice, we know that

24        1

----  =   ----  =   1

24        1

So the fraction of practice time spent playing music is:

[tex]\frac{24}{24}-\frac{3}{24} -\frac{4}{24}=\frac{17}{24}[/tex]

Step-by-step explanation:

660 times 790

The area of the rectangular park which having 660 meter and 790 meter is  521400 m².

How to find area of rectangle ?

A = l b is the formula for the Area of a Rectangle. Once the length and width of a rectangle are known, the area is calculated. The area of a rectangle can be calculated by multiplying its length and width.

The area is the amount of space covered by a flat surface of a specific shape. It is expressed as a "number of" square units. The number of unit squares that can fit into a rectangle is defined as its area. Rectangular shapes include the flat surfaces of laptop monitors, blackboards, painting canvas, and so on. The space occupied by these objects can be calculated using the area of a rectangle formula.

In this figure 1 cm = 100 m

6.6 cm * 100m = 660 m

7.9 cm * 100m = 790 m

Area of the park =  521400 m²
