Find the distance between (3,5)
and (7,-3). **(round to the nearest tenth.)
Answer:
The answer is
8.9 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3,5)and (7,-3)
The distance between them is
[tex]d = \sqrt{( {3 - 7})^{2} + ({5 + 3})^{2} } \\ = \sqrt{ ({ - 4})^{2} + {8}^{2} } \\ = \sqrt{16 + 64} \\ = \sqrt{80} \\ =4 \sqrt{5} \\ \: \: \: \: = 8.9442[/tex]We have the final answer as
8.9 units to the nearest tenthHope this helps you

How many garbage cans should be placed in each campground? Explain how you can use addition or multiplication to find the answer
Answer:
Step-by-step explanation:
Multiplication
Ratio of Tables to garbage = 8:3
Small camp ground:
40 picnic tables and let x be the number of garbage cans
[tex]\frac{8}{3}=\frac{40}{x}\\\\\frac{8*5}{3*5}=\frac{40}{x}\\\\\frac{40}{15}=\frac{40}{x}\\\\[/tex]
x = 15
Small campground with 40 picnic table needs 15 garbage cans
Large picnic ground:
120 picnic tables and let y be the number of garbage cans
[tex]\frac{8}{3}=\frac{120}{y}\\\\\frac{8*15}{3*15}=\frac{120}{y}\\\\\frac{120}{45}=\frac{120}{y}[/tex]
y= 45
Big campground with 120 picnic table needs 45 garbage cans
Can some one explain please
Answer:
D
Step-by-step explanation:
The sum to infinity of a geometric sequence is calculated as
[tex]S_{infinity}[/tex] = [tex]\frac{a}{1-r}[/tex] | r | < 1
where a is the first term and r the common ratio
Here a = 1 and r = [tex]\frac{1}{5}[/tex] , thus
[tex]S_{infinity}[/tex] = [tex]\frac{1}{1-\frac{1}{5} }[/tex] = [tex]\frac{1}{\frac{4}{5} }[/tex] = [tex]\frac{5}{4}[/tex] → D

Answer: [tex]\dfrac{\sqrt2}{2}[/tex]
Step-by-step explanation:
sin 75 = sin(30 + 45) = sin30 · cos45 + cos30 · sin45
[tex]=\dfrac{1}{2}\cdot \dfrac{\sqrt2}{2}+\dfrac{\sqrt3}{2}\cdot\dfrac{\sqrt2}{2}\qquad =\dfrac{\sqrt2+\sqrt6}{4}[/tex]
sin 15 = sin(45 - 30) = sin45 · cos30 - cos45 · sin30
[tex]=\dfrac{\sqrt2}{2}\cdot \dfrac{\sqrt3}{2}-\dfrac{\sqrt2}{2}\cdot\dfrac{1}{2}\qquad =\dfrac{\sqrt6-\sqrt2}{4}[/tex]
sin75 - sin15
[tex]=\dfrac{\sqrt2+\sqrt6}{4}-\dfrac{\sqrt6-\sqrt2}{4}[/tex]
[tex]=\dfrac{\sqrt2+\sqrt6-\sqrt6+\sqrt2}{4}\\\\=\dfrac{2\sqrt2}{4}\\\\=\dfrac{\sqrt2}{2}[/tex]

AB is dilated by a scale factor of 3 to form A1B1. Point O, which lies on AB, is the center of dilation. The slope of AB is 3. The slope of A1B1 is . Through point O.
Answer:
[tex]Slope\ of\ A'B'= 3[/tex]
Step-by-step explanation:
Given
[tex]Slope\ of\ AB= 3[/tex]
Required
Determine the slope of A'B'
Represent the coordinates of AB with (x,y), such that
[tex]AB = (x,y)[/tex]
Since A'B' is 3 * AB, we have
[tex]A'B' = 3 * AB[/tex]
Substitute (x,y) for AB
[tex]A'B' = 3 * (x,y)[/tex]
[tex]A'B' = (3x,3y)[/tex]
Since the slope of AB = 3, then the slope of A'B' is also equal to 3 because dilation through (0,0) does not have effect on the slope
Answer:
3, Does not Pass

Derrick got a pizza for lunch. He gave his friend 1/4 of the pizza and his sister 3/8 of the pizza. How many pizza he will have left
Answer: 3/8
Step-by-step explanation: 1/4 x 2 = 2/8 + 3/8 = 5/8 pizza gone. 1 - 5/8 = 3/8
ANSWER: 3/8
let's assume that Derrick is a nice guy and his pizza is an integer of 1
first he gave his friend a quarter so we subtract [tex]\frac{1}{4}[/tex] from 1
[tex]1-\frac{1}{4}[/tex]
now we rewrite 1 as a fraction with a denominator of 4 so that we're able to subtract: [tex]\frac{4}{4}-\frac{1}{4} =\frac{3}{4}[/tex]
now that Derrick still has [tex]\frac{3}{4}[/tex] of his pizza he's gonna give [tex]\frac{3}{8}[/tex] to his sister as well
meaning that we subtract again: [tex]\frac{3}{4} -\frac{3}{8}[/tex]
in order to be able to subtract different fractions, they got to have the same denominator, so we're going to multiply [tex]\frac{3}{4}[/tex] both numerator and denominator by 2: [tex]\frac{2*3}{2*4} -\frac{3}{8} = \frac{6}{8} -\frac{3}{8} = \frac{3}{8}[/tex]
we can now conclude that Derrick is left with only [tex]\frac{3}{8}[/tex] of his pizza.

The triangle ABC is isosceles (AB = AC)
DE parallel to BC
You need to prove: The ADE triangle is isosceles
Answer:
ΔADE is isosceles
Step-by-step explanation:
Δ ABC is isosceles
AB ≅ AC
∠B ≅ ∠C
If DE parallel to BC
AD ≅ AE
∠D ≅ ∠E
ΔADE is isosceles
The isosceles triangle is a polygon with three sides, two being equal and the other unequal.
The angles D and E will also be equal and the A other different.

Answer:
the outlier is 4
Look at all the numbers in the set:
24,18,26,20,18,24,4,24
the numbers 24,18,26,20,18,24,24 are all close in range to each other but the number 4 is not.
so therefore, the outlier is 4.
Answer:
4
Step-by-step explanation:
All the other numbers are close lying numbers. But, 4 sets off the set of data.

Over the summer, Kelly read 19 books. Elyse read 6 more
books than Kelly did. How many books did Elyse read over
the summer?
Answer:
25
Step-by-step explanation:
Answer:
25 books
Step-by-step explanation:
So, we know that Kelly read 19 books.
Elyse read 6 more books than 19.
Therefore, to find the amount of books Elyse read, add 6 to 19:
[tex]6+19[/tex]
Add:
[tex]=25[/tex]
So, Elyse read 25 books.
1588 nearest thousand answer me fast ♥️
Answer:
2,000
Step-by-step explanation:
Look at the hundreds place. It has a 5 in its place. The rule for rounding is that if the number directly to the right of the place you are rounding is 4 or below, you round down. If it's 5 or above, you round up. It has a 5 in its place, so we round up. The 5 becomes a 0, and the 1 in the thousands place becomes a 2. All other places are 0 because the rounding up affects all other places.I hope this helps!

Solise is planting 24 bushes and 16 trees in equal rows. She wants all the rows to be exactly the same with no plants left over. What is the greatest number of rows Solise can plant?
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
Since Solise want to plant both trees and bushes in the same number of rows, you need to find the common factor.
Since the question is asking what the greatest number of rows she can plant, you have to find the greatest common factor.
The greatest common factor of 24 and 16 is 8.
You can plant 24 bushes in 8 rows (meaning you can divide it by 8), and 16 trees in 8 rows (meaning you can divide it by 8). Since the greatest number you can divide them both by is 8, the GCF of 24 and 16 is 8.
So the greatest number of rows Solise can plant is 8 rows.

Write the equation in standard form for the ellipse with center at the origin, vertex (-8, 0), and co-vertex (0,4).
Answer: [tex]\dfrac{x^2}{64}+\dfrac{y^2}{16}=1[/tex]
Step-by-step explanation:
The standard form for an ellipse is: [tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] where
(h, k) is the centera is the radius on the x-axisb is the radius on the y-axisGiven: (h, k) = (0, 0)
a = 8 (distance on x-axis from origin to -8)
b = 4 (distance on y-axis from origin to 4)
Input h = 0, k = 0, a = 8, b = 4 into the standard form for an ellipse:
[tex]\dfrac{(x-0)^2}{8^2}+\dfrac{(y-0)^2}{4^2}=1[/tex]
[tex]=\dfrac{x^2}{64}+\dfrac{y^2}{16}=1[/tex]
