Answers

Answer 1

Answer: it’s a 90 degree angle. So the equation so be 28+2x =90 and find x from there.

28+2x=90
-28 -28
2x= 62
x=31

Answer 2

Answer: His error was he put 180 rather than 90 because it’s and acute angle so the number you minus by would be 90 done and then you finish the equation like he did

Write the Value of x

Answers

Answer:

Step-by-step explanation:

2*11=22

22+6=28=28

so it is equal it means that x value is eleven

The answer is 11 because since you are trying to find the value of x you would have to isolate x. The way you would is bring 6 to the other side with 28 because what ever you do to one side you have to do the other side. So, 28 - 6 = 22.

2x = 22
Now you can divide 2 by 2 and 22 by 2 so x is alone. 22/2 = 11 and that is the value of x.

Nina's garden is 4 1/5 meters long and 3/10 meter wide. what is the area of nina's garden

Answers

Area of rectangular garden = 21/5 $*$ 3/10 = 63/50 =1 $* \n$ 13/50 $m^(2)$ = 1.26 $m^(2)$

Consider Nina' s Garden is rectangular in shape

Length of the garden = 4 $*$ 1/5 = 21/5

Width of the garden = 3/10

Area of the rectangle is given by

Area = Length $*$ Width

So the area of the garden is given by

Area= 21/5 $*$ 3/10 = 63/50 =1 $* \n$ 13/50 $m^(2)$ = 1.26 $m^(2)$

For more information please refer to the link

Area= length * width

length = 4 1/5= 21/5 . Multiply the whole number with the denominator. 4*5= 20 . Add 20 with the numerator. 20+1=22

width= 3/10

21/5* 3/10 ( Multiply the denominators together). ( Multiply the numerators together).

21*3 / 5*10

A 30-minute TV program consists of three commercials, each 2 1/2 minutes long, and four equal-length entertainment segments. How long is each entertainment segment? What is the strategy plans and answer.

Answers

The length of each segment can be determine by subtract the length of three commercial.

The length of each segment is 5 minute 37.5 seconds.

Given:

Duration of TV program is 30 minute.

Duration of TV commercials is $2(1)/(2) \:\rm minutes$ .

Calculate the total length of three commercials.

$\begin{aligned}\rm {Total\: length}=(2(1)/(2))*3\n=2.5* 3\n=7.5\n\end$

Subtract 7.5 from total 30 min TV program.

$=30-7.5\n=22.5$

Now calculate the equal length of entertainment segments.

$\begin{aligned} \rm {Equal\: Length}=(22.5)/(4)\n= 5.625 \:\rm min\n\n=5 \:\rm min\:\rm and\: 37.5\: second\end$

Thus, the length of each segment is 5 minute 37.5 seconds.
