Express square root of 169^5 using rational exponents
Answer:
The square root is 371293.
Step-by-step explanation:
We solve this question using properties of exponents.
The square root of 169 is 13, so the exponent given can be written as:
[tex]169^{5} = (13^{2})^5 = 13^{10}[/tex]
The square root of [tex]13^{10}[/tex] is given by:
[tex]\sqrt{13^{10}} = 13^{\frac{10}{2}} = 13^5 = 371293[/tex]
The square root is 371293.

Answer:
Slope 'm' = [tex]\frac{5}{2}[/tex]
And y-intercept = 2
Step-by-step explanation:
Slope-intercept form of a line is given by the equation,
y = mx + b --------(1)
Here, m = slope of the line
b = y-intercept
Given equation is,
5x - 2y = -4
2y = 5x + 4
y = [tex]\frac{5}{2}x+2[/tex]
By comparing this equation with equation (1),
Slope 'm' = [tex]\frac{5}{2}[/tex]
And y-intercept = 2

Missing addend: 1/2 + 1/4
Missing Sums: 5/8 and 3/4
Step-by-step explanation:
The pattern of the addend is that the first term increases by 1/8 and the second term is always 1/4. If only the first term increases by 1/8, that means the total sum will increase by 1/8 each time also.

Hey there!
When you see the word “of” in mathematical statement, it usually means “multiply” (aka Multiplication)
“3/5 of 5/9”
3/5 • 5/9
MULTIPLY the NUMERATORS (TOP NUMBERS) from each other & also MULTIPLY the DENOMINATORS (BOTTOM NUMBERS) from each other!
3(5) / 5(9)
3(5) = 15 ⬅️ NUMERATOR
5(9) = 45 ⬅️ DENOMINATOR
15/45
The GCF (Greatest Common Factor) for both of your numbers is: 15.. so DIVIDE both the NUMERATOR and DENOMINATOR from 15
15 ÷ 15 / 45 ÷ 15
15 ÷ 15 = 1 ⬅️ NUMERATOR
45 ÷ 15 = 3 ⬅️ DENOMINATOR
Answer: 1/3 ☑️

I GIVEEEEE BRASINLILST
Answer:
Answer: Choice G.
Step-by-step explanation:
Dilations
Suppose a point P(x,y) is dilated across the origin, that is, the origin is the center of dilation, by a scale factor k.
The image of P is P' whose coordinates are P'(kx,ky).
If an image is formed by several points and each one is dilated by the same factor, then:
If |k| > 1, the image maps to a stretched or larger image.
If |k| < 1, the image maps to a shrunk or shorter image.
We have a hexagon graphed on a coordinate grid. The hexagon is dilated to create a larger hexagon. This means k must be greater than 1 and it should multiply each original coordinate (x,y).
Options F and H don't multiply by the coordinates but add to them, thus they are not valid answers.
Option J actually multiplies by the factor 0.2 but since it's less than 1, it does not correspond to an enlargement.
Only option G multiplies by a factor 4/3=1.3 greater than 1.
Answer: Choice G.
A population has a standard elevation of 25.29 what is the approximate standard error of the mean for a sample size of 175
Answer:
D. 1.91
(got it right on edmentum)
for your assurance please look at the picture below↓Step-by-step explanation:
The standard error is 1.91.
How is Standard Error Calculated ?For a data set the standard error is calculated by the ratio of standard deviation and square root of the sample size.
[tex]\rm Standard \; Error= \dfrac{ \sigma}{\sqrt{n}}[/tex]
Substituting the values
Standard Deviation = 25.29
Sample size = 175
Standard Error = 25.29 / √175
Standard Error = 1.91
Therefore the standard error is 1.91.

There are three types of sweet in a jar and this table gives
some information about them.
Type of sweet Eclair Humbug Mint
Number of sweets (see picture 4 3x + 6 2x)
A sweet is chosen at random.
The probability it is an eclair is
15
Work out the probability it is a humbug.
Answer:
Answer:
2/3
Step-by-step explanation:
Given:
Number of eclairs = 3
Number of humbugs =2x+6=2(x+3)
Number of mints = x
Therefore, total number of sweets in the jar is,
s=3+2x+6+x=3x+9=3(x+3)
Now, probability of selecting a sweet to be humbug is given as:
p(humbug)= number of humbugs/number of sweets
p(humbug)=2(x+3)/3(x+3)=2/3
Therefore, the probability that it is a humbug is 2/3

[tex]m = \frac{1}{3}[/tex] --- slope
Step-by-step explanation:
Given
The attached graph
Required
Determine the slope and the y intercept
The [tex]y\ intercept[/tex] is at the point where [tex]x = 0[/tex].
From the graph:
[tex]y = 3;\ when\ x = 0[/tex]
Hence,
y intercept = 3
Next, we calculate the slope using:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
Where:
[tex](x_1,y_1) = (0,3)[/tex]
[tex](x_2,y_2) = (9,6)[/tex]
So, we have:
[tex]m = \frac{3 - 6}{0 - 9}[/tex]
[tex]m = \frac{-3}{- 9}[/tex]
[tex]m = \frac{3}{9}[/tex]
[tex]m = \frac{1}{3}[/tex]

4.6/6 = w/3
9514 1404 393
Answer:
w = 2.3
Step-by-step explanation:
It looks like you have ...
4.6/6 = w/3
To solve this, you need to clear the 3 from the denominator of the w term. Do that by multiplying both sides of the equation by 3.
3(4.6/6) = 3(w/3)
4.6(3/6) = w . . . . simplify (rearrange the product to make mental arithmetic easier: 3/6 = 1/2)
w = 2.3 . . . . . . . . do the arithmetic

The perimeter of the rectangle shown is 96 feet. Determine the length and width of the rectangle.
Answer:
45
Step-by-step explanation:
detrain of the value they was given
Answer:
Length = 37 feet
width = 11 feet
Step-by-step explanation:
First, let us find the value of x.
They've already given that the perimeter of this rectangle is 96 feet.
So,
4x - 7 + 4x - 7 + x + x = 96
10x - 14 = 96
10x = 96 + 14
10x = 110
Divide both sides by x.
x = 11 feet
And now we can find the value of the width and length.
Given that,
Length = ( 4x - 7 ) ⇒ ( 4 × 11 - 7 )
44 - 7
37 feet
Width = x ⇒ 11 feet
