By what percent will a fraction decrease if its numerator is decreased by 50% and its denominator is decreased by 25%?
Answer:
it will decrease by 60% I think
Step-by-step explanation:
Lets use the example 100/100 and do the thing you get 50/125=40%.
Answer:
[tex]33\frac{1}{3}[/tex]%
Step-by-step explanation:
We can use a random fraction with numbers that make this problem easier to calculate. We can start with the fraction [tex]\frac{1}{1}[/tex] (1). If its numerator is decreased by 50% and its denominator is decreased by 25%(75% of it), the new fraction will be [tex]\frac{0.5}{0.75}[/tex] , which is the same as 2/3
The percent decrease from 1 to 2/3 is 33.333....% or [tex]33\frac{1}{3}[/tex]%.
You can use variables to solve this problem, but I find it easier to start with the fraction [tex]\frac{1}{1}[/tex] for calculation purposes.
Find the missing hypotenuse
Answer:
13
Step-by-step explanation:
[tex]a^{2} +b^{2} =c^{2} \\12^{2} +5^{2} =c^{2} \\13 = c[/tex]
Answer:
13
Step-by-step explanation:
5 raised 2 = 25
12 raised to 2 = 144
144 + 25 = 169
Square root of 169 = 13
Therefore the hypotenuse is 13 :)

Answer:
m < -18/19
Step-by-step explanation:
8m + 95 < -87 m +5
Add 87m to each side
8m+87m + 95 < -87 m+87m +5
95m + 95 < 5
Subtract 95 from each side
95m + 95-95 < 5-95
95m < -90
Divide each side by 95
95m/95 < -90/95
m < -18/19
Answer:
Step-by-step explanation:
8m +95 < -87m +5
8m +87m < 5-95
95m < -90
m < -90/95
m < -18/ 19

Answer:
You can tell that y=2 when x=4 by looking at the graph
Answer:
y = 2
Step-by-step explanation:
The equation is y = -x+6
Substituting 'x = 4' into this
y = -4+6
Hence, y = 2 when x =4

PLEASE I NEED HELP I DONT UNDERSTAND HOW TO DO ILL GIVW MORE IF RIGHT
From what I can tell from this problem, 130° and y° look to be both on the same 180° horizontal line. To find what y is, you just gotta subtract 130 from 180 and you get 50°. So y° is really, 50°.
Now for the x°. Even though we don't know what the numbers add up to in this diagram, let's assume since all triangles add up to 180° (and quadrilaterals are comprised of two triangles), that all angles of this quadrilateral are supposed to equal 360°. All you have to do is add the 123°, 60°, and 50° together to get 233°, now just subtract 233° from 360°, and your answer is 127°.
By the way my math might be a little off but I hope this helps you understand it. I hope.

Answer:
260 cm³Step-by-step explanation:
Full surface area:
S = 3(6*10) + 2(1/2*8*10) = 260 cm³Answer:
Surface Area = Surface Area of triangle + SA of rectangle
Surface Area = 3 × (6 × 10) + 2 × ½ × 8 × 10
Surface Area = 3 × 60 + 80
Surface Area = 180 + 80
Surface Area = 260 cm ³

In Circle P, EP = 2, PG = 12, and FP = 4.
What is the measure of PH?
A) 10
B) 16
C) 6
D) 8
Answer:
6
Step-by-step explanation:
FP * PH = GP * EP
If EP = 2, PG = 12, and FP = 4.
Then 4 * PH = 12 * 2
4 * PH = 12 * 2
step 1 simplify
4 * ph = 4PH
12 * 2 = 24
we now have 4PH = 24
step 2 divide each side by 4
4PH / 4 = PH
24 / 4 = 6
we're left with PH = 6

Solve the equation. How old is Sam?
Sam's age doubled plus 5 is the same as Sam's age tripled minus 1.
Answer:
Step-by-step explanation:
let the sam's age be x
2x+5=3x-1
5+1=3x-2x
6=x
therefore sam's age is 6.
Answer:
6
Step-by-step explanation:
let age be = to x
2x + 5 = 3x - 1
-x = -6
x = 6
Find the area. Round any decimals to the nearest tenth
Answer:
1.4
Step-by-step explanation:
Since we're finding the area, we need to multiply 1.2 times 1.2, which would give us 1.44, and since it says to round to the nearest tenth, we need to round it. If the number is 4 or under, we round down, if it's 5 and up we round up. In this case, we round down- so we end up with 1.4.
Answer:
A = L x 4
1.2cm x 4 = 4.8 cm^3

Which value is equivalent to
3/11?
OA A. 0.27
O
B. 0.27
OC
C. 3.6
OD. 3.
Answer:
0.27 repeating.
Step-by-step explanation:
So to solve this we just have to use division.
1 clearly doesnt go into 3 at least one time, so we can add a decimal point and add a 0 to make it 30.
11 goes into 30 2 times, so we have:
0.2
and 30-22=8
So we can add another 0 and make it 80.
Then 11 goes into 80 7 times. So we have:
0.27
and 80-77=3
So again, add the 0, we have 30.
11 goes into 30 2 times, so:
0.272
and 30-22=8
Add another 0 we get 80.
11 goes into 80 7 times.
So finally, we have:
0.2727.
This is a repeating decimal.
This can be shown as:
0.27
So this is your answer!
I was a bit confused with which one it was on your answer key, but knowing that it is 0.27 I am guessing you can chose!
Hope this helps!

Find the common difference for an arithmetic series with
a1=5 and S10 = 320.
Answer:
6
Step-by-step explanation:
Let [tex]n = a_{10}[/tex]. We know the formula for the sum of an arithmetic sequence is:
[tex]S_{n} = \frac{n(a_{1}+a_{n} )}{2}[/tex]
Where n is the number term you are finding the sum up to, a1 is the first term, and an is the nth term. We can substitute what we have:
[tex]320=\frac{10(5 + n)}{2}[/tex]
[tex]640=10(n+5)\\64=n+5\\n=59[/tex]
The formula to find the nth term of an arithmetic series is:
[tex]a_{n} = a_{1} + (n-1)d[/tex]
Where d is the common difference. Again, we can plug in what we have;
[tex]59 = 5 + 9d\\9d = 54\\d = 6[/tex]
