Can someone help me? Forgot how to do this, it’s been awhile

Answer:

The area would be 40.5 cm ^2

Step-by-step explanation:

Well first you don’t gotta worry about some isosceles trapezoid thingy.

You just gotta know the formula for a trapezoid is (b1+b2)/2)h

B1 in this case is or base 1 (9 or 4.5)

b2 in this case is or base 2 (9 or 4.5)

(you can only choose one base for each)

ANd you add those 2 up and you’d get 13.5

13.5/2 which is 6.75

Now we multiply it by the height which is 6 and gte 40.5

40.5cm ^2 is the final answer

Answer:

It will take 22 seconds for the thermometer to hit the ground.

Step-by-step explanation:

A thermometer falls from a weather balloon at a height of 7,744 ft.

This means that the initial height is of 7744ft.

h(t) = -16t2 + initial height

So

[tex]h(t) = -16t^2 + 7744[/tex]

How many seconds will it take for the thermometer to hit the ground?

This is t for which [tex]h(t) = 0[/tex]. So

[tex]0 = -16t^2 + 7744[/tex]

[tex]16t^2 = 0 + 7744[/tex]

[tex]t^2 = \frac{7744}{16}[/tex]

[tex]t = \sqrt{\frac{7744}{16}}[/tex]

[tex]t = 22[/tex]

It will take 22 seconds for the thermometer to hit the ground.

It sounds as though x is odd. The other two sides have length x+2. Perimeter of quadrilateral = 2x + 2(x+2) = 4x + 4

Answer:

where's the pic?

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

UT^2 = UV * UW

6^2 = (x - 7)(x - 7 + 5)

36 = (x - 7)(x - 2)

36 = x^2 - 2x - 7x + 14

x^2 - 9x - 22 = 0

(x - 11)(x + 2) = 0

x - 11 = 0  or  x + 2 = 0

x = 11

UW = x - 7 + 5

UW = 11 - 7 + 5

UW = 9

Answer:

m + 8 ≥ -8

1st choice: WRONG

m + 8 ≤ -8

-3 + 8 ≤ -8

5 ≤ -8

2nd choice: WRONG

-m + 8 ≤ -8

-(-3) + 8 ≤ -8

11 ≤ -8

3rd choice: RIGHT

m + 8 ≥ -8

-3 + 8 ≥ -8

5 ≥ -8

4th choice: WRONG

-m + 8 ≤ -8

-(-3) + 8 ≤ -8

11 ≤ -8

Answer:

[tex]\frac{5}{12}[/tex] cups

Step-by-step explanation:

This question is asking for the difference between the two values so subtraction is necessary

[tex]\frac{3}{4} -\frac{1}{3}[/tex]

Multiply the top and bottom of the first fraction by 3 and the second one by 4[tex]\frac{3*3}{4*3} -\frac{1*4}{3*4} = \frac{9}{12} -\frac{4}{12}[/tex]

Now just substract

9 - 4 = 5  ==>  [tex]\frac{9}{12} -\frac{4}{12} = \frac{5}{12}[/tex]

Answer:

15 cm on the map is equal to 25 miles.

Step-by-step explanation:

Given that,

On a map, 9 cm represents 15 miles.

The distance between two cities is 15 cm. We need to find the distance in miles.

9 cm = 15 miles

[tex]1\ cm=\dfrac{15}{9}\ \miles[/tex]

So, 15 cm is equal to,

[tex]15\ cm=\dfrac{15}{9}\times 15\ miles\\\\=25\ miles[/tex]

So, 15 cm on the map is equal to 25 miles.

Answer:

a. y = -5x + 4

Step-by-step explanation:

Given the following data;

Slope, m = -5

Intercept, c = 4

Mathematically, the equation of line is given by the formula; y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the given parameters, we have;

y = -5x + 4

Answer:

3.5 in

Step-by-step explanation:

Circumference = 2π(radius)

7π = 2π (radius)

7π/2π = radius

Pi in numerator and denominator cancel each other.

7/2  = radius

3.2 in = radius

Answer:

9,500 bottles.

Step-by-step explanation:

1 cubic meter = 1000000 milli liters

We can convert (2.85 cubic meter) to (milli liters) as

1 cubic meter = 1000000 milli liters

2.85 cubic meter = X milli liters

If we Cross multiply and find X, we have

X milli liters = [(2.85 cubic meter × 1000000 milli liters) ] / 1 cubic meter

X= 2850,000 milli liters

Then (2.85 cubic meter) will be equal to ( 2850,000 milli liters)

Capacity of the Bottle = 300 ml

Number of bottles that 300 ml capacity can be filled out of it =

(2850,000 milli liters) / (300 ml)

= 9,500 bottles.

Answer:

[tex]5 + 7x \le 33[/tex]

Step-by-step explanation:

Given

[tex]Base\ Charge = 5[/tex]

[tex]Additional = 7[/tex] per mile

[tex]Total = 33[/tex]

Required

Determine the inequality

First, we need to determine the total cost for x miles.

[tex]Cost = Base\ Charge + Additional * x[/tex]

[tex]Cost = 5 + 7 * x[/tex]

[tex]Cost = 5 + 7x[/tex]

The total cost can not exceed the amount he has, so the inequality is:

[tex]Cost \le Total[/tex]

[tex]5 + 7x \le 33[/tex]

Answer:

g = 4

h = 4.5

Step-by-step explanation:

The corresponding sides of two similar figures are proportional to each other.

Therefore,

[tex] \frac{g}{3} = \frac{8}{6} = \frac{6}{h} [/tex]

✔️Find g:

[tex] \frac{g}{3} = \frac{8}{6} [/tex]

Cross multiply

g*6 = 8*3

6g = 24

Divide both sides by 6

g = 24/6

g = 4

✔️Find h:

[tex] \frac{8}{6} = \frac{6}{h} [/tex]

Cross multiply

8*h = 6*6

8h = 36

h = 36/8

h = 4.5

Answer:

The p-value falls between 0.005 and 0.01.

Step-by-step explanation:

Random sample of 30 observations, you obtain t = 2.35

This means that the pvalue is 1 subtracted by the pvalue of Z = 2.35, as we are testing that the mean is more than a value.

Looking at the z-table, z = 2.35 has a pvalue of 0.9906

1 - 0.9906 = 0.0094

So, between 0.005 and 0.01.

Answer: The p-value falls between 0.01 and 0.02.
