Hey there,

To find percent of error you will start by subtracting 270 from 302

302 - 270 = 32

32 • 100 = 3200

3200 / 270 = 11.9

11.9 rounds to 12% so
about 12%

Hope I helped :)

jeka94

Answer:

85%

Step-by-step explanation:

Evan had 120 baseball cards. He gave 18 of them to his friend and the rest to his brother.

The number of baseball cards he gave to his brother is :

120 - 18 = 102 baseball cards

The percent of the baseball cards he gave to his brother is calculated as:

(Number of baseball cards given to his brother/ Total number of baseball cards) × 100

= 102/120 × 100

= 85%

The percent of baseball cards Evans gave his brother is 85%

In an isoceles triangle two angles are equal
if u take the coordinates and apply it in the graph it makes and isoceles triangle
as the y-axis is zero two of the ends will be level and x-axis is equal on both sides of the origin so (0,4) will be the third non equal angle

There are 2820 cars in Farmington. The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size ca
oee [108]

Answer:

Number of full size cars = 900

Step-by-step explanation:

The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size cars is 8 to 9. Since compact cars are  there in both ratios , we need to  make the number in the ratio for compact cars to be the same.

\frac{medium}{compact} = \frac{7}{5}

Multiply by 8 on numerator and denominator

\frac{medium}{compact} = \frac{56}{40}

\frac{compact}{full size} = \frac{8}{9}

Multiply numerator and denominator by 5.

\frac{compact}{full size} = \frac{40}{45}

Ratio of medium, compact and full size are in ratio 56,40,45.

Total number of cars =2820.

(56 + 40 + 45)x = 2820

x = \frac{2820}{141}

x = 20

Number of full size cars = 20\times 45 =900
