x = 180 - 76 - 63

x = 41°

Step-by-step explanation:

Answer:

x =41

Step-by-step explanation:

The three angles form a straight line so they add to 180 degrees

76+ x+ 63 = 180

Combine like terms

139 + x = 180

Subtract 139 from each side

139-139 + x = 180-139

x =41

Of all 840 sixth grade students in a math school, 700 participated in the math Olympiad. Of all 910 fifth grade students, 745 participated in it.From which grade did more students participate in the Olympiad?

Answers

Answer:Sixth grade

Step-by-step explanation:

Given

There are [tex]840[/tex] sixth grade students out of which [tex]700[/tex] Participated in math olympiad

also no of fifth grade students[tex]=910[/tex]

Fifth graders who participated in math olympiad [tex]=745[/tex]

Answer:

x ≈ 33

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan67° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{14}[/tex]

Multiply both sides by 14

14 × tan67° = x, thus

x ≈ 33 ( to the nearest whole number )

A 48​-inch board is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece. The shorter piece is ______
inches long.

Answers

Answer:

12 inches long

Step-by-step explanation:

So you have the ratio x : 3x

4x = 48

x = 12

Plug in:

12 * 1 = 12

The length of the shorter piece is 12 inches if the 48​-inch board is cut into two pieces. One piece is three times the length of the other.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

A 48​-inch board is cut into two pieces. One piece is three times the length of the other.

Let x and y be the length.

x = 3y

x + y = 48

3y + y = 48

y = 12 inches

x = 36 inches

Thus, the length of the shorter piece is 12 inches if the 48​-inch board is cut into two pieces. One piece is three times the length of the other.

An angle measuring 32 degrees has a complement that measures ( 2x-16 ) degrees. What is the value

Answers

Answer:

x=37

Step-by-step explanation:

Complementary angles add up to 90 degrees.

Let's first find the measure of the complement.

90-32=58

Now we can set the numerical value of it equal to the expression it gave us.

2x-16=58

We have to isolate x.

Lets add 16 to both sides

2x=74

Divide both sides by 2.

x=37

PLS HURRY I NEED THIS ANSWERED RIGHT NOW!!! Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has. What expression represents the amount of money Brittney has? What expression represents the amount of money that Brittney and Sun have together? What is the equation described in this problem?

Answers

Sun's money = x

Brittney's money = 2x

x + 2x = $60

3x = $60

3x/3 = 60/3

x = 20

So amount that Brittney has is 2x.

The amount they have together is 3x

The equation that describes the problem is 3x = $60

Answer:

Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has.

What expression represents the amount of money Brittney has?

✔ 2x

What expression represents the amount of money that Brittney and Sun have together?

✔ 2x + x

What is the equation described in this problem?

Step-by-step explanation:

if a cylinder has a volume of approximately 125.6 cubic cm and has a height of 10cm what is the length of the radius

Answers

Answer:

radius = 4 cm

Step-by-step explanation:

To find the length of the radius, we will follow the step below;

First, write down the formula for finding the volume of a cylinder

v=πr²h

where v is the volume of a cylinder

r is the radius      and

h is the height of the cylinder

from the question given,

v=125.6    and h = 10 cm

we can now proceed to insert the values into the formula and solve for r

note that π is a constant which is equal to 3.14

v=πr²h

125.6 =3.14×r×10

125.6 =31.4 r

Divide both-side of the equation by 31.4

125.6/31.4 =31.4 r/31.4

4 = r

r =4 cm

The length of the radius = 4 cm
