Find the area of the triangle

Answer:

A. is not true

Step-by-step explanation:

[tex]\angle{BCA}[/tex] appears to be acute, and [tex]\angle{BCD}[/tex] appears to be its obtuse supplement.

Just to be sure the diagram isn't lying to you, set this up:

4x + 9 + (9x - 11) = 180

13x - 2 = 180

13x = 182

x = 14

[tex]m\angle{BCA}=65^\circ\\m\angle{BCD}=115^\circ[/tex]

Those two angles are not congruent.

Answer:

I'm pretty sure your answer is 3, -4

Step-by-step explanation:

Answer:

[tex]Speed = \frac{Distance}{Time } = \frac{120}{3} = 40mph[/tex]

T = 75minutes = (75/60) hours

[tex]Distance = Speed \times Time = 40 \times \frac{75}{60} =\frac{40\times 75}{60} = 50miles[/tex]

Answer:

It would be 125 fish.

Step-by-step explanation:

This is because since there are 10 crustaceans for every 25 fish, there are 2.5 times more fish than crustaceans. Therefore, if there were 50 crustaceans, you would do 50 * 2.5 to get 125 fish.

answer:

x = 3

y = 6

step-by-step explanation:

y = 2x

3x - y = 3

3x - 2x = 3

3x - 2x = 3

x = 3

y = 2x

y = 2(3)

y = 6

Answer:

See Explanation

Step-by-step explanation:

Given

The function is not clear, so I will use:

[tex]x(t) = 2+ 3t + t^2[/tex]

Required

Speed over 2 to 10s

This is calculated as:

[tex]Speed = \frac{x(a) - x(b)}{a - b}[/tex]

Where

[tex](a,b) =(2,10)[/tex]

So, we have:

[tex]Speed = \frac{x(2) - x(10)}{2 - 10}[/tex]

[tex]Speed = \frac{x(2) - x(10)}{-8}[/tex]

Calculate x(2) and x(10)

[tex]x(2) = 2+ 3*2 + 2^2 =12[/tex]

[tex]x(10) = 2+ 3*10 + 10^2 =132[/tex]

So, we have:

[tex]Speed = \frac{12 - 132}{-8}[/tex]

[tex]Speed = \frac{-120}{-8}[/tex]

[tex]Speed = 15[/tex]

Answer:

x = 0 , y = 8

Step-by-step explanation:

x = y - 8 -----(1)

7x + 2y = 16 --------(2)

Substitute (1) in (2)

7(y - 8) + 2y = 16

7y - 56 + 2y = 16

9y = 72

y = 8

Substitute y in (1)

x = 8 - 8 = 0

Answer:

x = 5

y = 6

Step-by-step explanation:

Let's Solve for x-value first:

By the midsegment theorem we can say;

18 = 2x + 8

18 - 8 = 2x

10 = 2x

10/2 = x

5 = x

Now that we have x-value, let's figure out y-value similarly;

22 = 4y - 2

22 + 2 = 4y

24/4 = y

6 = y

There is the answer!

x = 5, and

y = 6

Answer:

25 squared cm

Step-by-step explanation:

Use the formula A = [tex]\frac{1}{2}[/tex]h ([tex]b_{1} + b_{2}[/tex])

h = height

[tex]b_{1}[/tex] = base 1

[tex]b_{2}[/tex] = base 2

A = [tex]\frac{1}{2}[/tex] (5) (7.2 + 2.8)

A = 25

Answer:

416 cm^2

Step-by-step explanation:

The formula for the area of a trapezoid is:

[tex]\frac{(b1+b2)*h}{2}[/tex]

where b1 and b2 are the bases and h is the height. We can plug what we have into the formula:

[tex]\frac{(14 + 38)*16}{2}[/tex]

[tex]\frac{(52)*16}{2}[/tex]

[tex]52*8[/tex]

416 cm^2

Answer:

The middle one because there is only 1 value of y for every value of x.

Answer:

8211 miles

Step-by-step explanation:

Delia flew 2416 miles on the first year of the job

She flew 3719 miles on the second year of the job

She flew 2076 miles more than the first and second year combined on the third year

= 2416+3719

= 6135

= 6135+2076

= 8211

Hence Delia flew 8211 miles on the third year

Answer:

y = 25

Step-by-step explanation:

Substitute x = 5 into the equation for value of y

Am subtracting because he made a down payment so I can get  the remaining of the money.

Let x = # of months

You use the remaining of the money to divide by 30 because of his monthly payments.

x = 22

Divide by 30 to isolate the variable x.

Answer:

49degrees

Step-by-step explanation:

The sum of angle on a straight line is 180degrees, hence;

x + y + z = 180

x + 45 + 86 = 180

x + 131 = 180

x = 180 - 131

x = 49degrees

Hence the value of x is 49degrees

The statement that correctly compares the two functions on the interval [-1, 2] is that Both functions are increasing, but function g increases at a faster average rate.

Exponential functions are kwon to be a type of function that is often written in the form: y = abx.

Where:

b = constant ratio.

a = initial value.

One can known this function if a given table of ordered pairs, has  x increasing by a constant value and the value of y increases by a common ratio.

From the Exponential table, we can see that the two functions (x, fx)are increasing, but only that of function g was said to have increases at a faster average rate.
