can someone solve these math problems pls

Answer:

Step-by-step explanation:

b/c it's the complement of 47 we know it's 180-47 = x

or

x = 133°

Answer:

x = 133 degrees

Step-by-step explanation:

The 47 degrees is a corresponding angle with the angle on the right of x. Meaning that angle is also 47 degrees. After figuring that out, all you have to do is do subtraction (180-47=133) to get your answer.

Answer:

1/8 cups per teaspoon

Step-by-step explanation:

5/8 cup sugar per 5 teaspoons of vanilla

(5/8 ) divide in 5 will give us how much per 1 teaspoon

(5/8)/5 = (5/8) * (1/5) = 5*1/ 8*5 = 1/8

Answer:

you can use SSA to prove congruence. side DE and AB are congruent, and C and F are both right angles

Answer:

yes, that information is sufficient

Step-by-step explanation:

when y is given, you can prove that the triangles are congruent by RHS axiom. R- right angle H-hypotenuse S- side

Answer:

A. The y-intercept represents the amount of money Stephanie has. She started at -16 because she spent $16.

B. The x-intercept is the amount of cups of lemonade she sold. On the graph, it shows that after 8 cups, she made 16 dollars back. She didn't make any profit sense she started at -16.

C. The slope represents how much she made after so many cups of lemonade were sold. It was after 8 cups of lemonade were sold that she started making a profit.

Step-by-step explanation:

Given:

The bases of trapezoid measuring 4 m and 12 m.

To find:

The median of the trapezoid.

Solution:

The median of the trapezoid is the average of its bases.

[tex]\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}[/tex]

The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:

[tex]\text{Median}=\dfrac{4+12}{2}[/tex]

[tex]\text{Median}=\dfrac{16}{2}[/tex]

[tex]\text{Median}=8[/tex]

Therefore, the correct option is C.

Answer:

D

Step-by-step explanation:

sorry if the answer is wrong

Answer:

the statement will be true

Answer:

the answer is 9.

Step-by-step explanation:

The total stimulations in which all three elevators are working is 12(option d) by the concept of data representation.

Data Representation: A method for analyzing numerical data is data representation. Data representation is used to create a diagram that shows the connections between facts, ideas, information, and concepts. It is a fundamental learning technique that is clear-cut and uncomplicated. The data type in a particular domain is always what determines it. There are many various styles and sizes of graphical representations.

According to the given data:

A building has 3 elevators.

The following set of random numbers represents 20 stimulations of the elevators, with 0, 1 representing the broken elevator and 2,3,4,5,6,7,8and 9 representing a working elevator.

Stimulation data:

931 188 763 841 559 144 652 277 653 673 404 396 011 843 599 797 414 761 273 844

Now, as we observe from the given data, the stimulation in which all three elevators are working are-

763,559,652,277,653,673,396,843,599,797,273,844a total of 12 stimulations.

Thus, the total stimulations in which all three elevators are working is 12

Hence, option d is correct.

Answer:

  (-5, -2)

Step-by-step explanation:

That point P can be found from ...

  P = A + 1/5(B -A)

  P = (4/5)A +(1/5)B = (4A +B)/5

  P = (4(-6, -4) +(-1, 6))/5 = (-24-1, -16+6)/5 = (-25, -10)/5

  P = (-5, -2)

Answer:

the answer is (-5,-2)

Answer:

c. 492 cubic centimetres

Step-by-step explanation:

the equation for the volume of a rectangular prism is

V = Length × Width × Height

we also have to take into account that there are 2 rectangular prisms in that picture so we have to add the volumes of both of them.

for the one on the bottom, the volume would be

V = 9 × 6 × 8

V = 432 cubic centimetres

now we'll do the one on the top

V = 3 × 5 × 4

V = 60 cubic centimetres

now we'll add up both volumes to get a total amount.

432 + 60 = 492 cubic centimetres

Answer:

the probability of getting doubles is 1 / 6

I hope this may be helpful

Answer:

it is 1/36

Step-by-step explanation:

if you want to get doubles, you have a chance of 1 out of 6 on each die. All you have to do from here is multiply them

1/6*1/6=1/36

Answer:

-10, -4

Answer:

126 burned calories per hour

There are 60 minutes in 1 hour, so ir you multyply 21 x 6 your answer will be 126.

Answer:

126

Step-by-step explanation:

there are 60 minutes in an hour so divide 60 by 10 to get 6 and multiply by 21 to get 126

Answer:

1) A week: $151.74

2) A month : $606.96

3) A years : $7890.48

Step-by-step explanation:

Custodian at Movie Theater

pay:$9.95

per hours:

15.25 hours per week

How much do they make in

1) a- week

1 week = 15.25 hours

Hence,

1 hour = $9.95

15.25 hours = x

Cross Multiply

x = 15.25 × $9.95

x = $151.7375

Approximately = $151.74

2) A month

There are 4 weeks in a month

1 week = $151.74

4 weeks = x

Cross Multiply

x = 4 × $151.74

x = $606.96

3) A year

There are 52 weeks in a year

Hence,

1 week = $151.74

52 weeks = x

Cross Multiply

x = 52 × $151.74

x = $7890.48

Therefore, they made in :

1) A week: $151.74

2) A month : $606.96

3) A years : $7890.48

Answer: 11. A and B

12. 520 cubic feet.

Step-by-step explanation: 11. The volume for a prism is base x height. Thus, it would be 2 x 3 x 3 or 6 x 3 to get a total of 18 cubic units.

12. The first compartment's volume is 5 x 7 x 8 or 280. The second compartment is 5 x 6 x 8 or 240. The total would be 280 + 240 or 520 cubic feet.

Answer:

11.B

12.520

Step-by-step explanation:

5.7.8=280

5.6.8=240

TOTAL=520

Answer:

The first answer choice= y = 50x

Step-by-step explanation:

Because you find a point on the graph that is exactly on a point and divide the y by the x and you get the constant. THen in the answer choices only  y = 50x is a larger number than 25 which in this case is the constant!

Step-by-step explanation:

Answer:

1.2m

Step-by-step explanation:

1 meter = 100 cm

120cm * (1m/100cm)  = 1.2m

Answer:

Part A

The vertex of the graph lies at (40,18). This is the maximum value on the graph. This means the balloon reached a maximum altitude of 1,800 meters about 40 minutes after its launch.

Part B

One of the x-intercepts of the function lies somewhere between x = 82 and x = 83. This is this point where the balloon is at zero altitude, or sea level. So, the balloon stays in the air for a little over 82 minutes. There is another x-intercept to the left of the origin. But a negative time value doesn’t make sense. So, we won’t considerate it for this scenario.

Part C

The -y-intercept of the function lies at (0,2). This is the starting point of the balloon’s journey. The point the balloon launched from was 200 meters above sea level.

Part D

We can’t interpret negative time values in this situation. So, the domain of the function is restricted to positive values of x. A negative y-value indicates an altitude below sea level. While some locations have negative altitudes, we can consider only positive values for this scenario. So, we should only consider positive values of y. So the domain of the function is restricted to only those values of x that produce positive values of y. Since we can’t see the x-intercept clearly from the graph, we’ll consider the domain of the function to be [0, 82].

Part E

Average rate of change on [0, 20] = f(20)-f(0) / 20-0

= 14-2 / 20

= 12 / 20

=0.6

Average rate of change on [60, 80] = f(80)-f(60) / 80-60

= 2-14 / 20

= -12 / 20

= -0.6

In this case, the rate of change represents the change in the balloon’s altitude within a time interval. The average rate of change on [0, 20] is positive. This indicates that the balloon is ascending, or climbing, during the first 20 minutes of its journey.

The average rate of change on [60, 80] is negative. This indicates that the balloon is descending between 60 and 80 minutes. Although negative, the rate of change in the second interval has the same absolute value as the rate of change for the first interval. So, during the last 20 minutes the balloon is descending at the same rate it was ascending during the first 20 minutes.
