In ΔRST, \text{m}\angle R = (11x+3)^{\circ}m∠R=(11x+3) ∘ , \text{m}\angle S = (x+15)^{\circ}m∠S=(x+15) ∘ , and \text{m}\angle T = (2x+8)^{\circ}m∠T=(2x+8) ∘ . Find \text{m}\angle R.M∠R.
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°
In the diagram below, find the value of x to the nearest hundredth
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?
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
a. Three-fourths
b. StartFraction 9 Over 10 EndFraction
c. 1 1/9
d, 4 1/2
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.
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

Answer:
y = (4/3)x
Step-by-step explanation:
You have to find the y-intercept, b. Do this by substituting in the x and y values into the equation:
12 = (4/3)(9) + b
12 = 12 + b
b = 0
So, y = (4/3)x
Hope that helps! :D
Answer: y = 4/3x
y = -3/4x + 1 ⇔ 3x + 4y - 4 = 0
have:
(d): perpendicular to 3x + 4y - 4 = 0
contains the point (9;12)
=> (d): 4x - 3y + 3.12 - 4.9 = 0 ⇔ 4x - 3y = 0 ⇔ y = 4/3.x

what is the difference between 3/8 and 61/64 redosed
Answer:
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
= 37/64

The diagram shows ∆QRS. Which term describes point T?
A. circumcenter
B. Orthocenter
C. Incenter
D. Centroid
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.

x + 12 = -5
O A. x= -17
B. X= -7
O c. x= 17
O D. x = 7
Answer:
x=-17
Step-by-step explanation:
Original Equation;
x+12=-5
The 12 will cross the equal sign so it will become -12. So it's going to be;
x=-5-12
There are two negative number so you add them and when you add them it would still be negative. And you would have to add them because when there are two negative numbers without any other sign you will have to add so it's going to be;
x=-17
