Answer:

22 7/18 pounds

Step-by-step explanation:

A: 15 1/2 pounds

B: 15 1/2 x 1/3 = 5 1/6

C: 5 1/6 x 1/3 = 1 13/18

A+B+C = 15 1/2 + 5 1/6 + 1 13/18 = 403/18 = 22 7/18

A trapezoid has an area of 150 square meters. If the bases are 14 meters and 16 meters, what us the height of the trapezoid?
goldenfox [79]
To find the area of a trapezoid, we use the following formula:
a = \frac{1}{2} (b1 + b2) \times h
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.

So, we have got the following information
a = 150
b1 = 14
b2 = 16

Filling in the formula gives us:
150 = \frac{{1} }{2} \times (14 + 16) \times h
150 = \frac{1}{2} \times 30 \times h
150 = 15 \times h
Finally we have to divide both sides by 15.
h = 150 \div 15 = 10
Therefore, the height of the trapezoid is 10 meters.

Please help! The answer is not A I got this question wrong.
Veronika [31]

Answer:

Right option is (D).

ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Step-by-step explanation:

We have given,

Two triangles ΔABC and ΔDBE such as :

\frac{BD}{BA} =\frac{BE}{BC}

This relation will contribute to side side similarity.

Also,

∠B = ∠B  , This will contribute as an angle similarity .

So combining above two relations,

\frac{BD}{BA} =\frac{BE}{BC}

and ∠B = ∠B

we can conclude that the triangle  ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Hence the right option is (C)

Lily goes car shopping and finds two cars. The first one burns fossil fuel, gasoline, that sells for $18,000. It will cost $100
Anna007 [38]

Answer:

Cost to buy and run the first car for 5 years=$24000

Cost to buy and run the second car for 5 years=$26000

I think we should buy the first car, because It is cheaper to buy and maintain

Step-by-step explanation:

first car:

Cost $18000 to buy

Cost $100 to maintain each month

5years =5 x 12=60months

Cost to maintain for 60months=100x60=$6000

First car cost to buy and run over the 5 year period=18000+6000=$24000

Second car:

It cost $22400 to buy

Cost $60 to maintain each month

5years=60months

Cost to maintain for 60months is 60 x 60=$3600

Cost to buy and run over the second car for 5years is 22400+3600=$26000

Sturdy’s paper plates cost $3.12 for 24 plates. Tough’s paper plates cost $4.32 for 32 plates. Which is the better buy?
Ksivusya [100]

Answer:

Sturdy's paper plates

Step-by-step explanation:

Let's see how much 8 plates cost:

Sturdy

24/3=8

$3.12/3= $1.04

Tough

32/4=8

$4.32/4=$1.08

$1.04<$1.08

Because Tough's paper plates costs 4 cents more for 8 plates, Sturdy's paper plates are the better buy.
