Step-by-step explanation:

Answer:

50 degrees

Step-by-step explanation:

The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:

Given that the triangle is a right triangle, the sum of angles will be:

(4x)°+(7x-20)°+90=180

simplifying and solving for x we get:

4x+7x-20+90=180

11x=180+20-90

11x=110

dividing both sides by 11 we get:

(11x)/11=110/11

this gives us

x=10°

Thus substituting the value of x in:

∠ACB=(7x-20)°

=(7*10-20)

=70-20

=50°

Answer: 50°

Answer: 6.5%

Step-by-step explanation:

Formula for simple interest : I = Prt , where P= principal , r= rate of interest  t= time

As per given , P = $2000 , I=$ 650, t= 5 years

Substitute all theses values in the formula , we get

[tex]650=2000\times r\times5\\\\\Rightarrow\ r=\dfrac{650}{2000\times5}\\\\\Rightarrow\ \dfrac{65}{1000}\\\\\Rightarrow\ r=0.065 =0.065\times100\%=6.5\%[/tex]

Hence, the required annual interest = 6.5%

Answer:

Gabrielle is 14 and Mikhali is 7

Answer:

let the age be x and 2x

2x+x=21

3X=21

X=7

Answer:

127+(-112)=15

Step-by-step explanation:

If you subtract 112 from 127, you can find the difference. Since 112 is Mya's weight, and the total is 127, we need to find out how much weight is left over after we take away Mya's weight, which would be the cat's weight. So if you follow the expression, which is 127+(-112), you would get a sum of 15 pounds. Since this is an addition problem, the expression would be 127+(-112) instead of 127-112. I hope you understand. The difference between 127 and 112 is the cat's weight, so the cat weighs 15 pounds.

Step-by-step explanation:

Add all the hours

Total profit divided by the amount of hours

Answer:

t < 4

Step-by-step explanation:

Reservation fee = $38

Additional fee per hour = $6.80

The history club wants to spend less than $65.20 on renting the meeting room.

t = number of hours the meeting room is rented

The inequality is

38 + 6.80t < 65.20

6.80t < 65.20 - 38

6.80t < 27.20

t < 27.20 / 6.80

t < 4

Therefore, number of hours the meeting room is rented should be less than 4 hours

Answer:

-[tex]17^\circ F[/tex]

OR

[tex]17^\circ F[/tex] decrease in the temperature.

Step-by-step explanation:

Given that:

Temperature at the night  = [tex]12^\circ F[/tex]

Temperature in the morning = -[tex]5^\circ F[/tex]

To find:

The total difference in the temperature = ?

Solution:

Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.

Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]

Negative value in the difference indicates that there is a decrease of the quantity.

So, the answer is:

-[tex]17^\circ F[/tex]

OR

there is decrease of [tex]17^\circ F[/tex] in the temperature.

Answer:

B?

Step-by-step explanation:

(This is math. Is that question supposed to be math? I'm not sure)

It is a binomial with degree 3

Explanation:

It has two terms: (−3xy2) and (5x2y) → it is a binomial

The degree of an expression is the largest sum of exponents of variables for any term in the expression.

−3xy2=−3x1y2 has a sum of exponents of variables =3

5x2y=5x2y1 also has a sum of exponents of variables =3

→ the expression has degree 3
