Answer:
x=0.8712, y=1.1818
Step-by-step explanation:
1.2x+1.4y=2.7 --(1)
0.4x-0.3y=0.9--(2)
1.2x=2.7-1.4y
x=(2.7-1.4y) / 1.2 --(3)
substitute (3) in (2)
[tex]0.4(2.7-1.4y) / 1.2 -0.3y=0.9[/tex]
[tex](1.8 - 0.56y) \frac{1}{3} - 0.3y = 0.9[/tex]
times both sides with 1/3
[tex] \frac{1}{3} (1.08 - 0.56y( \frac{1}{3} ) - 0.3y = 0.9)[/tex]
1.08-0.3=0.56y+0.1y
0.78=0.66y
y=1.1818
substitute y in (3)
x=2.7-1.4(1.1818) /1.2
x=0.8712

What additional information could you use to show that ΔSTU ≅ ΔVTU using SAS? Check all that apply.
Options
A. UV = 14 ft and m∠TUV = 45°
B. TU = 26 ft
C. m∠STU = 37° and m∠VTU = 37°
D. ST = 20 ft, UV = 14 ft, and m∠UST = 98°
E. m∠UST = 98° and m ∠TUV = 45°
Answer:
A. UV = 14 ft and m∠TUV = 45°
D. ST = 20 ft, UV = 14 ft, and m∠UST = 98°
Step-by-step explanation:
Given
See attachment for triangle
Required
What proves that: ΔSTU ≅ ΔVTU using SAS
To prove their similarity, we must check the corresponding sides and angles of both triangles
First:
[tex]\angle UST[/tex] must equal [tex]\angle UVT[/tex]
So:
[tex]\angle UST = \angle UVT = 98[/tex]
Next:
UV must equal US.
So:
[tex]UV = US = 14[/tex]
Also:
ST must equal VT
So:
[tex]ST = VT = 20[/tex]
Lastly
[tex]\angle TUV[/tex] must equal [tex]\angle TUS[/tex]
So:
[tex]\angle TUV = \angle TUS = 45[/tex]
Hence: Options A and D are correct
Its A and D

Sheet metal costs $1.88 per square foot. About how much
will Nick spend to cover the outside of the shed, not
including the bottom?
Answer:
Final Cost: $364.72
Step-by-step explanation:
We can see a picture of the shed attached below. To find the total cost we need to first find the surface area of the entire shed. The sides are rectangles, so to find the surface area we need to multiply the length by the width. Since there are two rectangular sides we multiply the result by 2.
A = L * W
A = 10 * 4.7
A = 47 sq ft. * 2sides
Total = 94 sq ft.
Now we calculate the bottom which is also a rectangle
A = L * W
A = 10 * 8
A = 80sq ft.
Now we need to calculate the surface area of the triangular sides and multiply the results by 2 since there are two triangular sides. The formula for the area of a triangle is half times base times height...
A = 0.5 * B * H
A = 0.5 * 8 * 2.5
A = 10 sq ft * 2 sides
Total = 20 sq ft
Finally, we need to add the entire surface area and multiply by the cost per square foot to find the total cost.
94 + 20 + 80 = 194 sq ft
194* 1.88 = $364.72
If the buses run on schedule, when is the next time a red line and a blue line bus will leave together? Show your work.
Answer:
So the next time they will leave together is 4:24 pm
Step-by-step explanation:
Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.
The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.
Factors of 6 = 2*3
Factors of 8= 2*2*2
In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M
L.C.M= 2*2*2*3= 24 minutes
So the next time they will leave together is 4:24 pm
A train arrives at the station with 150 passengers on board. 2/5 of the passengers get off the train in seattle , and then 35 passengers board the train . How many passengers are on the train when it leaves the station?
Answer:
95 passengers :) brainliest pls!
Step-by-step explanation:
2/5 = 0.4,
0.4*150 = 60,
60+35 = 95.

Jeremy had $32.50 in his savings account. He withdrew $4.50 each week for 3 weeks. How much money did he have left in the account after the 3 withdrawals?
Answer:
Jeremy have 19 dollars left.
Step-by-step explanation:
He withdrew $4.50 3 times, so he withdrew $4.50x3 = $13.50 in total
$32.50 — $13.50 = $19
Jeremy had 19 dollars left on his account.
A right rectangular prism has base dimensions of 2 1 /10 ft wide and 4 1/ 5 ft long. If the height of the prism is 3 1 /2 ft, what is the volume of the prism?
Answer:
2 1/10 x 4 1/5 x 3 1/2 = 30 87/100 feet
(Remember multiply one by one first multiply 2 1/10 x 4 1/5 = 8 41/50
then multiply 8 41/50 with 3 1/2 to get = 30 87/100 is your answer)
Step-by-step explanation:
Just multiply the given lengths. A 3 dimensional shape has to be given 3 sides in order to know the area/volume: Length x Width x Height

8. A truck is carrying peach juice, pear juice,
and grape juice bottles in a ratio of 4:3:5. If
there are 76 peach juice bottles, then how many
pear juice bottles are there?
Answer:
57 pear juices
Step-by-step explanation:
because we know we have 76 peach juices and the ratio is 4, so we get 19. This means that 19=x. And then we multiply 19 by 3 and we get 57.
What must be the annual payment you receive in order to earn 6.3% rate of return on a perpetuity that has a price of $245.1? (Answer in $s to the nearest cent, i.E. Xx.Xx, with no $-sign or commas needed.)
Answer:
the annual payment received is 15.44
Step-by-step explanation:
The computation of the annual payment received is shown below:
As we know that
Perpetuity = Payment ÷ rate of return
$245.1 = Payment ÷ 6.3%
So, the payment is
= $245.1 × 6.3%
= 15.44
Hence, the annual payment received is 15.44
We simply apply the above formula so that the annual amount could come

How many 3 digit numerical passwords are there if a digit can be repeated?
Any math experts can help please and thank you
Answer:
QUESTION:
How many 3 digit numerical passwords are there if a digit can be repeated?
ANSWER:
The first digit of the password can be any of the ten digits - 10 possibilities.
A digit cannot be repeated, so the second digit can be any digit except the one you chose for the first digit - 9 possibilities.
The third digit can be any digit except the digits you chose for the first and second digit - 8 possibilities.
Using the rule of product:
10 X 9 X 8 = 720
There are 720 passwords.
