Step-by-step explanation: 4 is equal to 2 so 4 is 110 degrees 4

110 x 2 = 220 360 - 220 = 140/2 = 70 so 3 and 1 = 70 degrees

lesya [120]

Answer:

Therefore the area of rectangle is increased by 15.5%.

Step-by-step explanation:

Assume the length and width of the rectangle be x and y respectively.

The area of the rectangle is = length×width

=xy.

Now the length of the rectangle is increased by 10%.

Then the length of the rectangle increased = $x\times \frac{10}{100}$ .

New length of the rectangle is $=x+\frac{10x}{100}$

$=\frac{100x+10x}{100}$

$=\frac{110x}{100}$

The width of the rectangle is increased by 5%.

Then the width of the rectangle increased = $y\times \frac{5}{100}$ .

New length of the rectangle is $=y+\frac{5y}{100}$

$=\frac{100y+5y}{100}$

$=\frac{105y}{100}$

New area of the rectangle is = $\frac{110x}{100}\times\frac{105y}{100}$

= 1.155 xy.

The percentage of area increase is

$=\frac{\textrm{New area - Original area}}{\textrm{Original area}}\times 100$

$=\frac{1.155xy-xy}{xy}\times 100$

$=\frac{0.155xy}{xy}\times 100$

=15.5.

Therefore the area of rectangle is increased by 15.5%.

A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/2 miles. At this rate, how many miles can the vehicle travel per gallon

valentina_108 [34]

Answer:

12 miles

Step-by-step explanation:

The problem above is related to the topic on "Equivalent Ratios." The missing term above is <em>"the number of miles that the vehicle can travel per gallon of gasoline."</em> In order to find this term, you have to use the "cross products."

Let n be the missing term.

$1\frac{1}{8} gallons$ / $13\frac{1}{2} miles$ = $\frac{1 gallon}{n}$

$\frac{9}{8} gallons$ / $\frac{27}{2} miles$ = $\frac{1 gallon}{n}$

$\frac{9}{8}$ x n = $\frac{27}{2}$ x 1 gallon

n = $\frac{27}{2}$ ÷ $\frac{9}{8}$

n = $\frac{27}{2}$ x $\frac{8}{9}$

n = 12 miles

Therefore, the vehicle can travel 12 miles per gallon of gasoline.

ludmilkaskok [199]

Answer:

23.42

Step-by-step explanation:

If something is decreasing by 7% we can mulitply it by (1-.07) or .93

so our formula is

100(.93)²⁰= 23.42388737

which rounds to 23.42
