Answer:
x = 12
y = 4.5
Step-by-step explanation:
Since ∆FGH ~ ∆KLJ, therefore, we would have the following proportion:
[tex] \frac{FG}{KL} = \frac{GH}{LJ} = \frac{FH}{KJ} [/tex]
[tex] \frac{9}{y} = \frac{x}{6} = \frac{6}{3} [/tex]
✔️Let's solve for x using:
[tex] \frac{x}{6} = \frac{6}{3} [/tex]
Multiply both sides by 6
[tex] \frac{x}{6}*6 = \frac{6}{3}*6 [/tex]
[tex] x = \frac{6*6}{3} [/tex]
[tex] x = 12 [/tex]
✔️Solve for y using:
[tex] \frac{9}{y} = \frac{6}{3} [/tex]
Cross multiply
[tex] y*6 = 3*9 [/tex]
6y = 27
y = 27/6
y = 4.5

Answer:
x = 5 and y = -6
Step-by-step explanation:
The given equations are :
6x + 3y = 12 ...(1)
4x + y = 14 ...(2)
Multiply equation (2) by 3.
12x + 3y = 42 ...(3)
Subtract equation (1) from (3).
12x + 3y-(6x + 3y) = 42-12
12x+3y-6x-3y = 30
6x = 30
x = 5
Put th value of x in equation (2).
4(5) + y = 14
20 +y = 14
y = -6
So, the solution of the equations are x = 5 and y = -6.

8(5 – 2x)
need help answering this question
Let's simplify this problem using the distributive property.
The first thing we want to do is change the minus to plus a negative.
Now distribute or multiply the 8 times
each of the terms inside the set of parentheses.
So we get 8(5) + 8(-2x) and this simplifies to 40 + -16x.

Jason wanted to place all 540 marbles in the 3 newly bought boxes. If he wants to
divide it in a ratio of 1:2:3, how many marbles would be in each box?
I really need your help please!!, thank you.
Answer:
The first box will have 90 marbles, the second 180 and the third 270.
Step-by-step explanation:
Division in a ratio of 1:2:3
1 + 2 + 3 = 6
So
The first box will have 1/6 of the marbles.
The second box will have 2/6 = 1/3 of the marbles
The third box will have 3/6 = 1/2 of the marbles.
First box:
One sixth, so:
(1/6)*540 = 540/6 = 90
Second box:
One third, so:
(1/3)*540 = 540/3 = 180
Third box:
One half, so:
(1/2)*540 = 540/2 = 270
The first box will have 90 marbles, the second 180 and the third 270.

A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 30 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 30 weeks and that the population standard deviation is 2.8 weeks. Suppose you would like to select a random sample of 56 unemployed individuals for a follow-up study.
Required:
a. Find the probability that a single randomly selected value is greater than 27.6.
b. Find the probability that a sample of size n=80 is randomly selected with a mean greater than 27.6.
Answer:
a) The probability that a single randomly selected value is greater than 27.6
P( X≥27.6) = 0.8051
b) The probability that a sample of size randomly selected value is greater mean greater than 27.6
P( X≥27.6) = 0.9998
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 30 weeks
The Standard deviation of the Population = 2.8 weeks
Let 'X' be a Normal distribution
[tex]Z = \frac{x-mean}{S.D} = \frac{27.6-30}{2.8} = -0.857[/tex]
The probability that a single randomly selected value is greater than 27.6
P( X≥27.6) = P(Z≥-0.857)
= 0.5 + A(-0.857)
= 0.5 + A(0.857)
= 0.5 + 0.3051
= 0.8051
Step(ii):-
Let 'X' be a Normal distribution
[tex]Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } } = \frac{27.6-30}{\frac{2.8}{\sqrt{80} } } = -7.6677[/tex]
The probability that a sample of size randomly selected value is greater mean greater than 27.6
P( X≥27.6) = P(Z≥-7667)
= 0.5 + A(-7.667)
=0.5 +0.4998
= 0.9998

A survey was carried out on 40 travelers . 12 of them said they had traveled to Ghana and not to Cameroon. 8 said they had travelled to Cameroon and not Ghana. 10 said they had not traveled to either one of the countries. Draw a Venn diagram to find 1. The number of travelers that had gone to both countries before. 2. The number of travelers that had gone to Ghana before.
It’s urgent.
Answer:
10 ; 22
Step-by-step explanation:
Ghana = G
Cameroon = C
Cameron only = 8
Ghana only = 12
Total sampled = 40
Both Ghana and Cameroon = x
Not traveled to either = 10
Ghana only + Cameroon only + both Ghana and Cameroon + not traveled to either = total sampled
12 + 8 + x + 10 = 40
30 + x = 40
x = 40 - 30
x = 10
Number that had gone to Ghana before :
Ghana only + both
12 + x
12 + 10
= 22

Answer:
each side of the hexagon measures 40 cm (which agrees with answer B)
Step-by-step explanation:
Recall that a regular hexagon has six equal sides, therefore, each side would be one sixth of the 240 cm:
each side of the hexagon = 240 cm / 6 = 40 cm
Find the radius and the diameter to the nearest hundredth when C = 7π yd. Use 3.14 for π.
60 POINTS PLEASE GIVE VALID ANSWER
Answer:
Diameter = 7
Radius = 3.5
Step-by-step explanation:
Hi! Ace here.
So, the formula to find circumference is dπ or 2rπ
So to find the diameter, you do the circumference/π
To find the radius, you'd do the circumference/2π
Plug-in those numbers and there you go!
Hope this helps, let me know if you have any questions.
I know this was a very vague explanation so I encourage you to ask any questions. Thank you!

Answer:
m<7 = 49°
m<8 = 41°
m<9 = 49°
m<10 = 41°
Step-by-step explanation:
Given :
m<7 ≅ m<9
m<8 = 41°
m<7 = 90° - m<8 (complementary angles)
m<7 = 90° - 41° (substitution)
m<7 = 49°
m<9 = m<7 (m<7 ≅ m<9)
m<9 = 49° (substitution)
m<10 = 90 - m<9
m<10 = 90 - 49
m<10 = 41°
