Answers

Answer:

<R = 124°

Step-by-step explanation:

Note that the sum of angles in a triangle is 180degrees. In a triangle RST

Given

∠R=(11x+3)°

∠S=(x+15)°

∠T=(2x+8)°

Required

∠R

First we need to get the value of x;

since <R+<S+<T = 180

11x+3+x+15+2x+8 = 180

11x+x+2x+3+15+8 = 180

14x+26 = 180

14x = 180-26

14x = 154

x = 154/14

x = 11°

get <R

Since <R = 11x+3

<R = 11(11)+3

<R = 121+3

<R = 124°

Hence the measure of <R is 124°

Answer:

x = √324 = 18

Step-by-step explanation:

x shows up only in the second problem, so I'll focus on that problem.

This is a right triangle because one of the three angles is 90 degrees.

Thus, the Pythagorean Theorem applies:  x^2 + 24^2 = 30^2, or

x^2 = 900 - 576 = 324

Then x = √324 = 18

Ray and Claudia are writing in journals. Ray has written 16 pages and he now writes 2 pages every day. Claudia has written only 2 pages, but she now writes 4 pages every day. In how many days will they have written the same number of pages?

Answers

Answer:

6 days

Step-by-step explanation:

Step one:

Given data

For Ray

He has 16 pages already

Now he is writing 2 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=2x+16-------------1

For Claudia

He has 2 pages already

Now he is writing 4 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=4x+2-------------2

Step two:

let us equate equation 1 and 2 to find x

2x+16=4x+2

collect like terms

2x-4x=2-16

-2x=-12

divide both sides by -2

x=12/2

x=6

Therefore it will take 6 days for them to have the same number of pages

What is the quotient of Three-fourths and StartFraction 5 Over 6 EndFract

Answers

Answer:

the quotient of Three-fourths and StartFraction 5 Over 6 EndFract is [tex]\frac{9}{10}[/tex]

Hence Option B is correct.

Step-by-step explanation:

We need to find quotient of Three-fourths and StartFraction 5 Over 6 EndFract

Writing in mathematical form: [tex]\frac{3}{4} \div \frac{5}{6}[/tex]

Solving, we get

(Converting division sign into multiplication the term is reciprocated so, 5/6 will become 6/5 )

[tex]\frac{3}{4} \div \frac{5}{6}\\=\frac{3}{4} \times \frac{6}{5}\\=\frac{3}{2} \times \frac{3}{5}\\=\frac{9}{10}[/tex]

So, the quotient of Three-fourths and StartFraction 5 Over 6 EndFract is [tex]\frac{9}{10}[/tex]

Hence Option B is correct.

What is the volume of a cylinder with a diameter of 30 cm and a height of 40 cm? Use 3.14 for pie. Round to the nearest 10th.

Answers

Answer:

28,260.0 cm^3

Step-by-step explanation:

The volume of a cylinder uses the equation π[tex]r^{2}[/tex]h.To find the radius, divide the diameter by two, getting r=1/2(30)=15. Plug in all numbers getting:

3.14(15^2)(40)

=3.14(225)(40)

=28260

Answer:

V ≈ 28,260 cm³

Step-by-step explanation:

V = πr²h where,

V = volume

r = radius

h = height

π = 3.14

To find the value of the radius, we take half of the diameter.

1/2(30) = 15

Now that we have all the values, we plug them into the equation and round.

V = (3.14)(15)²(40) = 28,260

V = 28,260

The answer is 7.

First, substitute the S for the 5 and you will have 9-8/4.
We know that fractions is just division so divide 8 and 4 to get 2. Then, subtract 2 from 9 to get 7.

= 3/24

= 1/8

= 1:8

C)

4:12

= 4/12

= 1/3

= 1:3

D)

5:40

= 5/40

= 1/8

= 1:8

E)

7:56

= 7/56

= 1/8

= 1:8

Distance between points =  [tex]37/64\\[/tex]

Step-by-step explanation:

This is a relatively simple problem. Here we have to find the distance between two points on the number line.

The given two numbers are fractions and to find the difference between these two numbers, we have to make their denominators common.

One has denominator as 8 and the other as 64.

We make the common denominator as 64.

Then the fractions 24/64 are 61/64  and .

The distance between the two points = 61/64  - 24/64

C. Incenter

Answers

Answer:

Step-by-step explanation:

A

The term which describes the point T in triangle QRS is option A. Circumcenter.

Here, given is a triangle QRS.

It is clear that three lines are drawn and all the three lines intersect at the point T.

Each of the line is perpendicular to each of the sides of the triangle.

And each of the line bisects each of the sides, that is sides are being divided in to half.

So T is the intersecting point of all the perpendicular bisectors of the sides, which is the definition of circumcenter.

Thus, T is the circumcenter of the triangle QRS.
