Step-by-step explanation:
The center of dilation is point S, so S' is at the same location. The other points move to 5/3 of their distance from S.
1. Write an equation to determine the height, h, of the building.
Answer: 5^2 +h^2 = 102
2. To the nearest tenth, determine the height of the
building.
Answer:
8.7 m
Step-by-step explanation:
Hi there!
[tex]5^2+h^2=10^2[/tex]
To find the height of the building, we need to isolate h on one side of the equal sign. We will do this by performing inverse operations to both sides (ex. the inverse of addition is subtraction, the inverse of multiplication is division, etc.)
Firstly, we can simplify both sides by squaring 5 and 10:
[tex]25+h^2=100[/tex]
Now subtract both sides by 25 to cancel it out on the left side and isolate h²:
[tex]25+h^2-25=100-25\\h^2=75[/tex]
Now, take the square root of both sides to isolate h:
[tex]\sqrt{h^2} =\sqrt{75} \\h=8.7[/tex]
Therefore, the height of the building is 8.7 m when rounded to the nearest tenth.
I hope this helps!

Whats 5x=234 please answer i will brainliest if i can
Answer:
x = 46.8
Step-by-step explanation:
I assume you are trying to find the value of x.
[tex]5x=234.[/tex]
To find x, divide the answer by the coefficient. The quotient is the value of 'x.'
[tex]234/5=46.8[/tex]
Therefore, 46.8 is the value of x.
Remember: Whenever you see a coefficient and a variable together—5x, 7y, 3t—this means to multiply them.
what is the length if the baseedge labeled X? Will mark brainliest if correct.

Travis has hired Charlie and Dora to plant flowers . Dora can plant 150 flowers in the same time it takes Charlie to plant 120 flowers , which can be shown using the following relationship where d and c are the respective rates at which Dora and Charlie can plant flowers :
150 =120
——. ——
d. c
Also , Dora can plant 18 flowers more per day than Charlie
How many flowers can Charlie plant per day ?
Answer:
21 flowers
Step-by-step explanation:
because if dora can plant 18 plants then Charlie can plant 21 flowers
PLEASE HELP!!! So the answer I got was 19.14 however that is not the correct answer. How do I solve this problem. Not sure what else to do.
Check the picture below.
so we know the radius of the semicircle is 2 and the rectangle below it is really a 4x4 square, so let's just get their separate areas and add them up.
[tex]\stackrel{\textit{area of the semicircle}}{\cfrac{1}{2}\pi r^2}\implies \cfrac{1}{2}(\stackrel{\pi }{3.14})(2)^2\implies 3.14\cdot 2\implies 6.28 \\\\\\ \stackrel{\textit{area of the square}}{(4)(4)}\implies 16 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{sum of both areas}}{16+6.28=22.28}~\hfill[/tex]

To solve this problem I multiplied $9.50 x 168 to figure out how much it would cost to feed the lambs. Unfortunately my answer, $1596, was incorrect. How would I solve this type of problem?
===========================================================
Explanation:
That calculation you wrote out would only apply if each lamb ate 1 full bale of alfalfa.
Instead, each lamb eats 1/8 of a bale. So you'll divide the 1596 value by 8 to get 1596/8 = 199.50
This is the same as saying (1/8)*1596 = 0.125*1596 = 199.50
---------------------
Or we can think of it like this
1 day = 1/8 bale of alfalfa
168*(1 day) = 168*(1/8 bale of alfalfa)
168 days = 21 bales of alfalfa
This says that one lamb will eat 21 bales of alfalfa over the course of 168 days
At $9.50 per bale, the total cost for one lamb is 9.50*21 = 199.50 dollars
This cost applies to one lamb only. So if you had say 3 lambs overall, then you'd multiply that by 3.

please help
Answer:
2
Step-by-step explanation:
Will appreciate it :)
Answer:
Step-by-step explanation:
In order for lines to be parallel they have to have the same slope. The first 2 equations there are solved for 5y, so let's do that to the last one--solve it for 5y--and put them all in the same order (the order that the first one is in; they will all look identical then). Equation #2 in the same order as in #1: 5y = 3x - 4. Equation #3 then becomes 5y = 3x - 1. Equations #2 and 3 have the same slope.
What is a inequality to represent -2 and -5
Answer:
-2 > -5
Step-by-step explanation:
Since -2 is greater than -5 we use the greater-than sign to represent this relationship.
Two classmates have decided to read all the volumes in a popular series of books. Carly has
already read 10 volumes and will continue to read new ones at a rate of 2 volumes per week.
Lisa, who hasn't started reading the series yet, will read 4 volumes per week. At some point,
Lisa will catch up with Carly and they will be reading the same book. How many volumes will
each girl have read by then? How long will that take?
Answer:
the volumes they would have read is 20
so it will take them 5 weeks
Step-by-step explanation:
C ( started with 10) < 12<14<16<18<20 =5 weeks
L (started with 0) <4 <8<12<16<20 = 5 weeks
for them to read the same book will take them 5 weeks and each of them would have read 20 volumes by then
Perimeter of 30 ft in an area of 14 ft what is the length and the width
Answer:
14 and 1
Explanation:
14 + 14 + 1 + 1 = 30
14 x 1 = 14
The perimeter is the sum of all 4 sides. Divide the perimeter in half fo the some of one length and one width:
Length + width = 15
Area is length x width
Find 2 numbers that when added equal 15 but when multiplied equal 14
15 + 0 = 15, 15 x 0 = 0
14 + 1 = 15, 14 x 1 = 14
The answer is 14 ft long by 1 ft wide

Solve for x if ab ≠ 2c
[tex]x = \frac{ac + b}{2c - ab} [/tex]
Refer to the attachment for step by step explaination.
Answer:
[tex]x=\frac{b+ax}{2c-ba}[/tex]
Step-by-step explanation:
When given the following expression, one is asked to solve for (x):
[tex]\frac{2x-a}{b}=\frac{ax+1}{c}[/tex]
Use cross products to rid the variable in the denominator,
[tex]c(2x-a)=b(ax+1)[/tex]
Simplify, distribute, multiply every term in the parenthesis by the term outside of it,
[tex]2xc-ac=bax+b[/tex]
Inverse operations, collect all terms with variable (x) on one side of the equation:
[tex]2xc-ac = bax + b\\\\2xc - bax = b + ac[/tex]
Factor, remove a like term that exists in both of these expressions,
[tex]x(2c-ba)=b+ax[/tex]
Inverse operations,
[tex]x=\frac{b+ax}{2c-ba}[/tex]
Simplify the expression by distributing. 4(w+8)
a)4w + 8
b)12w
с)4w + 32
d)4(8 + W)
Answer:
Option C
4w + 4(8)
