Ethen is ‘x’ years old. Raj is 8 years older than Ethen. Find the sum of their ages in 6 years time.
Answer:
2x+20
Step-by-step explanation:
Given
Age of Ethen = x
If Raj is 8 years older than Ethen, then;
Raj = x + 8
6 years time
Ethen age = x+ 6
Raj = x+8+6 = x+14
Sum of ages in 6 years time = x+6+x+14
Sum of ages in 6 years time = 2x + 20
Hence the required sum of ages is 2x+20

y2 = - 4
y1 = - 8
x2 = - 3
x1 = - 2
==========
Equation
m = (y2 - y1) / (x2 - x1)
m = (-4 - - 8) / (-3 - - 2)
m = 4 / - 1
m = - 4
Answer:
(1, -4)
Step-by-step explanation:
(-3, -4) >> (x1, y1)
(-2, -8) >> (x2, y2)
(y2 - y1) -8 - (-4) = -4
----------- >>>
(x2 - x1) -2 - (-3) = 1
x always goes first in a coordinate, so
(1, -4)

A plane flies 1.6 hours at 150 mph on a bearing of 10°. It then turns and flies 9.1 hours at the same speed on a
bearing of 100°. How far is the plane from its starting point?
9514 1404 393
Answer:
1386 miles
Step-by-step explanation:
The plane flies ...
(150 mi/h)(1.6 h) = 240 mi
on its first leg. Then it flies ...
(150 mi/h)(9.1 h) = 1365 mi
on the second leg. The flight directions differ by 90°, so the distance from the starting point can be found using the Pythagorean theorem.
c² = 240² +1395² = 1920825
c = √1920825 ≈ 1385.94
The plane is about 1386 miles from its starting point.
Find the value of x. Round to the nearest degree as needed.

Answer:
x° = 59°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations. The one applicable here is ...
Tan = Opposite/Adjacent
tan(x°) = 5/3
x° = arctan(5/3) ≈ 59.04°
The value of x is about 59.
Can someone help and give me a step by step explanation please?!

Answer:
∠QSR = 78°∠SQR = 51°Step-by-step explanation:
The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...
∠QSR = 2×∠QTR
∠QSR = 2×39°
∠QSR = 78°
__
Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...
∠QSR + 2(∠SQR) = 180°
78° + 2(∠SQR) = 180° . . . . fill in the value we know
2(∠SQR) = 102° . . . . . . . . . subtract 78°
∠SQR = 51° . . . . . . . . . . . . .divide by 2
1. If you multiply 6 by 1/4 will your answer be greater or less than 6. How do you know?
Answer:
less than 6
Step-by-step explanation:
when you multiply a number by a fraction less than 1 you are calculating a portion of that number so you get a result smaller.
Ron is making a triangular frame for a garden using three lengths of wood. He has three pieces of wood that measure 3 feet, 8 feet, and 4 feet in length.
Ron claims that he can make a triangular frame with these three pieces of wood. Do you agree with Ron? Explain your reasoning.
Answer:
Step-by-step explanation:
A side of the triangle must be shorter than the sum of the remaining two sides.
He cannot make a triangle with 3, 4, and 8.

Josephine started a business selling cosmetics. She spent $4500 to obtain her merchandise, and it costs her $200 per week for general expenses. She earns $550 per week in sales.
What is the minimum number of weeks it will take for Josephine to make a profit?
550w<4500+200w
200w≥4500+550w
550w>4500+200w
200w>4500+500w
Answer:
550w>4500+200w
Step-by-step explanation:
Expenses: $4500 + $200 per week
Income: $550 per week
We want income to be greater than expenses

Answer:
432 inches.
Step-by-step explanation:
The formula for finding the area of a triangle is;
[tex]\frac{b*h}{2}[/tex]
Using this, we can find the area of each individual piece.
[tex]\frac{6*6}{2} =18[/tex]
Now that we have this, we simply multiply 18 by 24, which gives us 432.

Which graph shows the zeros of the function f(x) = 2x2 + 4x – 6 correctly?
Answer:
Divide through by 2 .
x2 - 2x - 3 = 0 What two numbers add to -2 and multiply to -3 ? → +1 and -3
So...we can factor it like this...
(x + 1)(x - 3) = 0 Set each factor equal to zero and solve for x.
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3

Multiply each equation by a constant that would help to eliminate the y terms.
2x-5y = -21
3x-3y = -18
What are the resulting equations?
6x-15y = -63
- 15x+15y = 90
6x-15y = 63
-15x+15y = 90
6x-15y=-63
- 15x+ 15y = -90

find the product of (2y - 1) and (4y² + 2y + 1).
help.
Answer:
8y^3 - 1
I have made it in above picture
Answer:
8y³ - 1Step-by-step explanation:
(2y - 1) × (4y² + 2y + 1) =
= 2y×4y² - 1×4y² + 2y×2y - 1×2y + 2y×1 - 1×1 =
= 8y³ - 4y² + 4y² - 2y + 2y - 1 =
= 8y³ - 1
M is directly proportional to R cubed a)R = 4, M = 160 find M when R = 2 b) work out the value of R when M=540
Answer:
a k (proportionality constant) = 2.5
b. r = 6
Step-by-step explanation:
Here, we want to solve a variation
m = k * r^3
160 = k * 4^3
160 = 64k
k = 160/64
k = 2.5
b) secondly;
From;
540 = 2.5 * r^3
r^3 = 216
r = cube root of 216
r = 6

Answer:
A
Step-by-step explanation:
Hello there
The coefficient correlation is set on a scale of 1 to -1
1 having the strongest correlation, 5 having an ok correlation and 0 having no correlation
.193 is closest to 0 so the correlation is very weak
Remember if the coefficient correlation is positive the it will have a positive correlation and if its negative then it will have a negative correlation
So we can conclude that the answer is A
