Step-by-step explanation:
1). y2 - y1 / x2 - x1
7 - 9 / 5 - 6
= 2
2). y2 - y1 / x2 - x1
6 - (-2) / 3 - (-9)
= 2/3
3). y2 - y1 / x2 - x1
-8 - 1 / 8 - (-8)
-9/16
4). y2 - y1 / x2 - x1
-9 - (-8) / -1 - 2
= 1/3
Triangle ABC is similar to Triangle DEF. Use the similar triangles to
answer the questions. (The triangles are not to scale.)
(In pic)
a.) Find the length of the BC and DF.
b.) Find the perimeter of each triangle
please help ! thanks :)
Answer:
Below in bold.
Step-by-step explanation:
As they are similar corresponding sides are in the same proportion so
3/2 = BC/3
2BC = 3*3
2BC = 9
BC = 4.5.
3/2 = 5/DF
3DF = 2*5
DF = 2*5 / 3
= 3.33...
Perimeter of ABC = 3 + 4.5 + 5 = 12.5.
Perimeter of DEF = 2 + 3 + 3.33.. = 8.33...
Answer:
BC = 4.5 cm
DF = 10/3 cm
Step-by-step explanation:
Corresponding sides of similar triangles are in same ratio
[tex]\frac{BC}{EF}=\frac{AB}{DE}\\\\\frac{BC}{3} =\frac{3}{2}\\\\BC = \frac{3}{2}*3\\\\BC = \frac{9}{2}\\\\BC = 4.5 cm[/tex]
[tex]\frac{DF}{AC}=\frac{DE}{AB}\\\\\frac{DF}{5}=\frac{2}{3}\\\\DF = \frac{2}{3}*5\\\\DF = \frac{10}{3}[/tex]
Perimeter of ΔABC = 3 + 5 +4.5 = 12.5cm
Perimeter of ΔDEF = 2 + 3 + 3.3 = 8.3 cm

The Estrada family has established for cable internet service since the pandemic. When establishing the service, there was an initial fee as well as a monthly fee on the contract. c(m)=35m+40 represents this scenario. How much has the Estrada family paid for internet service if they began service in March 2020?
Given:
When establishing the internet service, there was an initial fee as well as a monthly fee on the contract.
The given function is:
[tex]c(m)=35m+40[/tex]
To find:
The cost of internet service if they began service in March 2020.
Solution:
We have,
[tex]c(m)=35m+40[/tex]
We need to find the internet service cost for the first month. So, substitute [tex]m=1[/tex] in the given function.
[tex]c(1)=35(1)+40[/tex]
[tex]c(1)=35+40[/tex]
[tex]c(1)=75[/tex]
Therefore, the cost of internet service is 75 if they began the service in March 2020.

Mind says Paint cost $29.95 per gallon nikki needs 3,6 gallons to complete the paint project please tell me the answer
Answer: [tex]\$107.82[/tex]
Step-by-step explanation:
Given
The cost of paint is [tex]\$29.95\text{per gallon}[/tex]
Nikki need [tex]3.6[/tex] gallons of paint
So, the cost of the paint is the product of the rate and volume of paint
Put the values

What is the potential energy of a 500kg elevator that is 4.0m high from the floor?
Answer:
19,600 JStep-by-step explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
We have
PE = 500 × 9.8 × 4
We have the final answer as
19,600 JHope this helps you

Answer:
0.45
Explanation:
the total probability of the spinner landing on red, blue or green is 0.20 + 0.12 + 0.08 = 0.40. thus, the remaining probability of the spinner landing on orange or pink is 1 - 0.40 = 0.60.
since the probability that the spinner will land on orange is three times that of pink, we can divide 0.60 by 3 + 1 to find the probability of it landing on pink:
0.60 ÷ 4 = 0.15
now, we can multiple this by 3 to find the probability that the spinner will land on orange:
0.15 × 3 = 0.45
i hope this helps! :D

Martina tiled 260 squared feet of her kithchen floor. She picked a tile that is $2.49 per square foot. She paid a 7% sales tax. How much did she spend to buy enough tile for her project
Answer:
$692.72
Step-by-step explanation:
Given data
The total area of tile = 260 squared feet
cost per squared foot of tile= $2.49
Hence the total for 260 squared feet cost will be
=260*2.49
=$647.4
Let us find the amount of 7% Tax
=7/100*647.4
=0.07*647.4
=$45.318
Hence the amount spent in all is
=45.318+647.4
=$692.72

Answer:
− ( x ^2 − 4 x − 1 )
Step-by-step explanation:
If sin12 = k determine cos24 in terms of k
Recall the double-angle identity,
sin²(x) = (1 - cos(2x)) / 2
Now if sin(12°) = k, then
k ² = sin²(12°) = (1 - cos(24°)) / 2
→ cos(24°) = 1 - 2k ²

A tractor travels at an average speed of 36km/hr for 10 sec.calculate the distance the tractor covers in 10 sec
Answer:
.1km
Step-by-step explanation:
The tractor can move .01 km in a second so 10 times .01 is .1
so the tractor can move .1km every 10 seconds
1 hour = 3600 seconds
10 seconds is 10/3600 = 1/360 of an hour
36 km per hour x 1/360 of an hour = 0.1 km (100 meters)

Round 245,675 to the nearest hundred thousand
The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.
What is round off?Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
here, given that,
Round 245,675 to the nearest hundred thousand
we know,
Anything at or above 50 gets rounded up.
49 and below gets rounded down.
so, we get,
here, to the nearest hundred thousand means 675 > 500
so, it will be 5,675 => 6000
we have,
Rounding off 245,675 to the nearest hundred thousand is:
246000
Hence, The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.
