The drawing below shows the dimensions of skims kite what is the area of Kim's kite ​
Leno4ka [110]

Answer:

48 square inches

Step-by-step explanation:

Given

See attachment for kite

Required

The area of the kite

The given kite has a triangular shape.

So, the area is:

Area = 0.5 * base * height

From the attachment

base = 12in

height = 8in

So:

Area = 0.5 * 12in* 8in

Area = 48in^2

Using Ratios to Solve Problems - Item 1457 Question 4 of 7 Evan's family drove to a theme park for vacation. They drove the same
azamat

Answer:

150 miles

distance travelled on the third day = 150 miles

Step-by-step explanation:

Note: it was given that they drove the same speed throughout the trip. That means their speed is constant for all days;

For the first day

distance = 300 miles

time = 6 hours

Speed = distance/time

Speed = 300/6 = 50 mph

on the third day;

time = 3 hours

Speed = speed on first day = 50 mph

distance = speed × time

distance = 50 mph × 3 hours

distance = 150 miles

distance travelled on the third day = 150 miles

The manager at the local auto shop has found that the probability that a car brought into the shop requires an oil change is 0.8
Ber [7]

Answer:

0.85

Step-by-step explanation:

Given two events A and B, the probability that either A or B occurs is given by:

p(A\cup B) = p(A)+p(B)-p(A\cap B)

where

p(A) the probability that A occurs

p(B) is the probability that B occurs

p(A\cap B) is the probability that both A and B occur at the  same time

In this problem, we know the following facts:

p(o) = 0.83 is the probability that the car requires an oil change

p(b)=0.17 is the probability that the car requires a brake repair

p(o\cap b) = 0.15 is the probability that the car requires both an oil change and brake repair

Therefore, the probability that either o (car requiring oil change) or b (car requiring brake repait) occur is:

p(o\cup b)=p(o)+p(b)-p(o\cap b)=0.83+0.17-0.15 = 0.85

11. Write 5 equivalent fractions for<br>• 6/7.​
almond37 [142]

\huge{\boxed{\frac{12}{14}}} \huge{\boxed{\frac{18}{21}}} \huge{\boxed{\frac{24}{28}}} \huge{\boxed{\frac{30}{35}}} \huge{\boxed{\frac{36}{42}}}

One really simple way to find an equivalent fraction is just to multiply the numerator and denominator.

For example, for the first answer, \boxed{\frac{12}{14}}, I simply multiplied the numerator and denominator each by 2.  This gives you an equivalent fraction.

You can then continue with this process using numbers such as 3, 4, 5, and 6 as your multiplication factor.
