Answer:
y = 1/2x - 5
Step-by-step explanation:
y = 1/2x + b
-3 = 1/2(4) + b
-3 = 2 + b
-5 = b

Given b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C. What is the area of the triangle? Round to the nearest hundredth.
Answer:
1.73 units
Step-by-step explanation:
The area of a triangle with sides a, b, c and angles A, B, C is given as
Area = 1/2 bc sin A
Given that b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C then the area
= 1/2 * 4 * 1 * sin 120
= 2 sin 120
= 2 * √3/2
= √3
= 1.732
To the nearest hundredth = 1.73

A number is 3 1/3 greater than another. If the sum of the numbers are doubled the answer would be 19 1/2
Answer:
smaller number = 3 5/24
larger number = 6 13/24
Step-by-step explanation:
let the larger number = x
smaller number = y
x - y = 3 1/3 equation 1
2(x +y) = 191/2 equation 2
divide equation 2 through by 2
x + y = 9 3/4 equation 3
subtract equation 1 from 3
2y = 6 5/12
y = 77/12 x 1/2 = 3 5/24
substitute for y in equation 1
x - 3 5/24 = 31/3
x = 3 1/3 + 3 5/24
x = 6 13/24
Answer:
3 and 5/24

Find the area of the figure.
Answer:
A = 132 cm²Step-by-step explanation:
Area of the figure is a sum of area of rectangle 4 cm × 7 cm and trapezoid with bases of 19 cm i 7 cm and altitude of 8 cm.
Therefore:
[tex]A=7\cdot4+\dfrac{7+19}2\cdot8=28+26\cdot4=132[/tex]

A car travelled at 50 km/hr for 3 hours How far did the car travel?
Answer:
25km
Step-by-step explanation:
50 km = x km
1 hr 3 hrs
From there, you cross-multiply and solve for x.
(50 km)*(3 hrs) = (x km)*(1 hr)
x km = (50)*(3)/(1) = 150km
Now, your other question can be answered the exact same way. 30 minutes is the same as 1/2 of an hour, so just put 0.5hrs in where the 3hrs was in the previous problem. So to show you how it works once more, here are your calculations:
50 km = x km
1 hr 0.5 hrs
(50 km)*(0.5 hrs) = (x km)*(1 hr)
x km = (50)*(0.5)/(1) = 25km
I hope that helps!

i've ask this 3 times and didn't get a correct answer
Answer:
240
Step-by-step explanation:
So to do this problem, you have to find the area of each 2d figure. To start off, you need to find the top sides. (to make this easier I won't show the work)
Green- Top & bottom: 16. Sides (4): 28
Pink- Top & bottom: 8. Sides (4): 20
Now you add it all up.
32+112+16+80=240
Answer:
224 in^2
Step-by-step explanation:
The pink rectangular prism has the dimensions 2 x 4 x 10 and the green has the dimensions 4 x 4 x 7. The formula for the surface area of a rectangular prism is:
2(lw + wh + lh)
We can substitute to find the surface area of both pink and green:
Pink
2(4 x 4 + 4 x 7 + 7 x 4)
2(16 + 28 + 28)
2(72)
144
Green
2(2 x 4 + 4 x 10 + 2 x 10)
2(8 + 40 + 20)
2(68)
136
The sum is 280. We have over-counted the part where the two prisms are next to each other. The area of the counted rectangle is 4 x 7 or 28. We over-counted twice, so we need to subtract 2 x 28 or 56.
280 - 56 = 224 in^2

Pablo bought chocolate bars that were divied into 8 equal pieces. If Pablo has eaten 20 pieces of chocolate, what is the fractionof chocolate bars he has eaten?
Answer:
Pablo has eaten 2 1/2 chocolate bars.
Step-by-step explanation:
We know that:
- Each bar was divided into 8 equal pieces
- Pablo ate 20 pieces
So, we can find the chocolate bars that he has eaten as follows:
[tex] f = \frac{1 \: bar}{8 \: pieces}*20 \: pieces = 2.5 \: bars = 2\frac{1}{2} \: bars [/tex]
Hence, Pablo has eaten two and a half of chocolate bars expressed as 2 1/2 as a mixed fraction.
I hope it helps you!

Find the area of the compound figure. Round your answer to 2 decimal places if required. (Use π = 3.14)
Hello! I’ve been stuck on this problem for a while and—though I know the answer—I’m not sure how to get to it? Please help!
Answer:
first you will need to break the shape into a semi circle and a triangle.
then solve the area of the semi circle. which is
[tex] \frac{(3.14) \times r ^{2} }{2} \\ [/tex]
[tex] \frac{(3.14) \times 4.6^{2} }{2} \\ = 33.22[/tex]
Then solve the area of the triangle.
First work out the height of the triangle, which is
[tex]13.4 - 4.6 = 8.8[/tex]
then the area. which is
[tex] \frac{1}{2} 4.6 \times 8.8 \\ = 20.24[/tex]
now calc. the two figures. which is
[tex]20.24 + 33.22 \\ = 53.46[/tex]

During summer vacation, Tori read, on average, 40 pages per night. Now that she has returned to school, she is averaging 5% fewer. How many pages per night is Tori averaging now?
Answer: 38 pages per night
Step-by-step explanation:
Tori used to read an average of 40 pages per night but now she is going at a rate that is 5% slower.
To find the number of pages she is reading now, first find 5% of 40 pages:
= 5% * 40
= 2
Then subtract this figure from 40:
= 40 - 2
= 38 pages per night
By deducting 5% from the reading quantity, the person is reading at 5% less.
