Answer:
32 : 9
Step-by-step explanation:
To write a ratio in its simplest form , the numerator and denominator should be reduced by their common factor(s).
64 = 2 × 2 × 2 × 2 × 2 × 2
18 = 2 × 3 × 3
⇒ Common factor of 64 & 18 is 2.
So , reducing 64 & 18 by 2 gives :-
[tex]\frac{64 \div 2}{18 \div 2} = \frac{32}{9}[/tex]
∴ Hence , the simplest form is 32 : 9.
Find the value of x.
Answer:
The answer is 148 or D
Step-by-step explanation:
The line has 180 degrees total, to find the answer you subtact 32 from 180. This leaves you with 148.
Answer: x = 148°
Step-by-step explanation: All supplementary angles equal 180°. So you subtract 32° from 180° (180°-32°) and get your answer.
The base and the height of Triangle A are half the base and the height of Triangle B. How many times greater is the area of Triangle B?
The area of Triangle B is
times greater
Answer:
Let's say that the base of triangle a is 2 and the height is 3. That makes the base and height of triangle b 4 and 6. To find the area of a triangle, use the formula 1/2 multiplied by height multiplied by base. So the area of triangle a is 2 multiplied by 3 multiplied by 1/2 giving us 3. The area of triangle b is 1/2 multiplied by 4 multiplied by 6 giving us 12. Since 12 divided by 3 is 4, the area of triangle b is 4 times greater than the area of triangle a.

9514 1404 393
Answer:
yes
Step-by-step explanation:
If GH║FE, then ∆DEF ~ ∆DHG.
In similar triangles, corresponding sides have the same ratios.
The ratios of corresponding sides are ...
DG/DF = DH/DE
DG/(DG + GF) = 18/(18+36)
(1/2GF)/((1/2GF +GF) = 1/3
(1/2)/(3/2) = 1/3
1/3 = 1/3
Corresponding sides are proportional. Angle D is congruent to itself, so ∆DEF ~ ∆DHG by the SAS similarity postulate. Angles DGH and DFE are therefore congruent and GH║FE.

What’s the value of x?
Answer:
6*15 = 5(x+5)
90 = 5x + 25
65 = 5x
x = 13
Step-by-step explanation:
I've gone ahead and labeled some points.
There is a formula that says PA*PB = PC*PD, this is what you use. If you would like me to show why this works I would be happy to.
So what we have is PA = 6, PB = 9+6 = 15, PC = 5 PD = 5+x so let;s writ ethe formula with these values
6*15 = 5(x+5)
90 = 5x + 25
65 = 5x
x = 13
EDIT: Here is the explanation for the formula
If you form triangles PCB and PAD you can find angle D and angle B are the same, because they are inscribed angles that intersect the same arc of the circle. Also angle P is the same on both triangles since they are the same angle, so this means both triangles are similar.
This means DA is similar to BC, AP is similar to CP and PD is similar to PB. Similar sides means if you can multiply one side by a number to get to its similar side, then you can multiply all sides by that value to get all sides of that similar triangle.
This also means if you divide one side by its similar side you get the scale value, so this means if you do it to two different sets of similar sides you get the same number
[tex]\frac{PA}{PC}=\frac{PD}{PB}\\PA*PB = PC*PD[/tex]
what is x? (7x+1)=(9x-7)
Step-by-step explanation:
Given
7x + 1 = 9x - 7
9x - 7x = 1 + 7
2x = 8
x = 8 / 2
x = 4

Answer:
z=19
Step-by-step explanation:
Researchers were investigating whether there is a significant difference between two medications, R and S, designed to reduce fleas found on cats. From a sample of 300 cat owners, the researchers randomly assigned 150 cat owners to use medication R on their cats and the remaining cat owners to use medication S. For the cats using medication R, 88 percent had no fleas. For the cats using medication S, 90 percent had no fleas. Which of the following is the most appropriate method for analyzing the results?
A two-sample z -test for a difference in population proportions
A two-sample z-test for a difference in sample proportions
A one-sample z-test for a sample proportion
A one-sample z-test for a population proportion
A one-sample z-test for a difference in sample proportions
Answer:
A) A two-sample z -test for a difference in population proportions
Step-by-step explanation:
To determine whether a difference in proportions is significant, the two-sample z-test for a difference in population proportions is the most appropriate method for the analysis.
The most appropriate method for analyzing the results is A. A two-sample z-test for a difference in population proportions.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter.
In this scenario, we have two different treatments (medication R and S) applied to two separate samples (150 cat owners each) and we want to determine if there is a significant difference in the proportion of cats with no fleas between the two groups.
This is a classic scenario for a two-sample z-test for a difference in population proportions, which tests the hypothesis that the difference in proportions between two independent populations is equal to zero.
Thus, a two-sample z-test for a difference in population proportions.
Hence, the correct answer would be option (A)

2(3x -8y) - 6 =
Answer:
6x - 16 y -6
Step-by-step explanation:
okay so first you have to distribute the 2 to the number inside the parenthesis
2(3x-8y) -6
you do 2 x 3x, which is 6x
then 2 x -8y, which is -16y
Now the new equation is 6x - 16 y -6

8(4n + 3) = – 72
show your work
Answer: n= −3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8(4n+3)=−72
(8)(4n)+(8)(3)=−72(Distribute)
32n+24=−72
Step 2: Subtract 24 from both sides.
32n+24−24=−72−24
32n=−96
Step 3: Divide both sides by 32.
32n/32 = −96/32
n=−3
Answer:
n= -3
Step-by-step explanation:
32n+24=-72
(subtract 24)
32n=-96
(divide by 3)
n=-3
Marty and Adam want to share 8/10 feet of rope, equally. What amount of rope should each person get?
Answer: 2/5 feet
Step-by-step explanation:
From the question, we are informed that Marty and Adam want to share 8/10 feet of rope, equally.
The amount of rope that each person would get would be calculated by dividing 8/10 by 2. This will be:
= 8/10 ÷ 2
= 8/10 × 1/2
= 8/20
= 2/5
Therefore, each person gets 2/5 feet of rope.
