Measurement maths!! If good with area please help

Mathematics
1 answer:
Gennadij [26K]2 years ago
4 0

Answer:

a. 15/2 or 7.5 sqcm

b. 20 sqcm

Step-by-step explanation:

Area of a triangle is (base × height)/2.

A = (5×3)/2

A = 15/2 = 7.5cm^2

The area of a parallelogram is just base × height, but yoy have to choose wisely what is the base and height. These two measurements must be perpendicular. So the 4 and 5 are perpendicular. We won't use the measurement 6cm at all.

Area = 4×5

Area = 20 sqcm

Convert 3/11 to a decimal equivalent using long division
Anastasy [175]

<span>In order to Convert 3/11 into a decimal, you have to divide 3/11 out. If you were to put the three on top, and the 11 on the bottom, (here's a little tip to make it easier " top dog stays out and snoopy stays in. Top dog would be 3 because it is on the top of the fraction. Snoopy would be the 11 which is on the bottom of the fraction.) so with that being said..... So if you do 3 divided by 11 The answer would be 0.27272727...hope it helped.

the cost to rent a hall for school functions is 60$ per hour. write an expression for the cost of renting the hall for h hours.
Firlakuza [10]
The expression for the amount of time rented would be:
C=60(h), I choose this expression because C would stand for cost, 60 for the amount per hour, and h for the piece of expression being given. Now when you need to find the amount per hour, the brackets means to times; so you'd plug in the hour needed to be found in h, and times 60 by the hour.

Your table should look like this :
COST PER HOUR            |            HOURS            |            COST
$60                                    |                 2                  |         $60 x 2 = $120
$60                                    |                 6                  |         $60 x 6 = $360
$60                                    |                 8                  |         $60 x 8 = $480
$60                                    |                10                 |         $60 x 10 = $600

Three Friends are starting a food truck and a contributing a total of 140,000 to begin operations. Their investments are in the
monitta

Answer:

Step-by-step explanation:

The sum of those numbers is 14.  Let's divide 14000 by 14 to get the number of parts (each part will be an investment in dollars) and we get 10,000.  So if a person invests 2 parts, he invests 2(10,000).  A person that invests 5 parts invests 5(10,000), and likewise for the person investing 7 parts: 7(10,000).  That gives us 20,000 + 50,000 + 70,000 = ?  

(140,000)

The difference in investment between the largest and the smallest is 50,000
