Answer:

<h2> Amount in liters is 47.9 liters</h2>

Step-by-step explanation:

The Question is incomplete, it does not provide the measurements or options to choose from, but we can estimate the answer

Step one:

Given data

Taryn Bought 12.6gallons of gasoline

1 gallon of gasoline is  3.8 liters

We want to convert from gallons to liters

Step two:

----if 1 gallon has 3.8 liters

then 12.6 gallons will have x liters

cross multiply we have

x= 12.6*3.8

x=47.88 liters

Hence the estimated amount in liters is 47.9 liters

Alex is buying a sweater that originally costs $35 and a pair of jeans that originally cost $28.If the sweater is marked down 30
Sladkaya [172]

Answer: $47.66

Step-by-step explanation:

The cost of the sweater is calculated by multiplying .7 x $35. (70% represents the cost of the sweater since there is a 30% discount.). The sweater cost $24.50.

The cost of the jeans is .85 x $28 = $23.80.

The total cost is $24.50 + $23.80 = $43.80.

The tax rate is 8%, which is calculated by multiplying .08 x $43.80 = $3.86 in sales tax.

Including the sales tax, the total cost is $43.80 + 3.86 = $47.66

What is the volume of a sphere with a radius of 3 m, rounded to the nearest tenth
expeople1 [14]
<h3><u>Given</u>:-</h3>

\rightarrowRadius(r) of sphere = 3m

<h3><u>To Find</u>:-</h3>

\rightarrow Volume of the sphere.

<h3><u>Formula Used</u>:-</h3>

\rightarrowVolume of sphere = \sf{\frac{4}{3}πr^3}

<h3><u>Solution</u>:-</h3>

\rightarrowVolume of sphere = \sf{\frac{4}{3}πr^3}(putting the value of r(radius) from the above given and pie(π) = \sf{\frac{22}{7}})

\rightarrow\sf{=\frac{4}{3}×\frac{22}{7}×3^3}

\rightarrow\sf{=\frac{4}{3}×\frac{22}{7}×27}

\rightarrow\sf{=\frac{2,376}{21}}

\rightarrow\sf{=113.14m^3}

Therefore, the volume of the sphere \sf{=113.14m^3}, which can be rounded off to it's nearest tenth as \sf{113.1m^3}

A 7 cm x 5 cm rectangle sits inside a circle with radius of 6 cm.
LenaWriter [7]

Answer:

78.04 square cm

Step-by-step explanation:

Area of shaded region = area of circle - Area of rectangle

= \pi \:  {r}^{2}  - l \times w \\  = 3.14 \times  {6}^{2}  - 7 \times 5 \\  = 3.14 \times 36 - 35 \\  = 113.04 - 35 \\  = 78.04 \:  {cm}^{2}

Given the equations 4x−py=6 and 5x+7y=10, find (a) the value of p that makes the lines parallel and (b) the value of p that make
Lubov Fominskaja [6]

Step-by-step explanation:

(a) the value of p that makes the lines parallel :

=> -4/-p = -5/7

5p = 7×(-4)

5p = -28

p = -28/5 = -5.6

(b) the value of p that makes the lines perpendicular :

=> -4/-p = -1 ÷ (-5/7)

4/p = 7/5

7p = 4×5

7p = 20

p = 20/7 = 2.86
