Sole The Equation 0.75q²=108 55 POINTS

Mathematics
1 answer:
rusak2 [61]2 years ago
5 0
Q= -12

Explain:
Basically we divide both sides by 0.75
Then expand 108 over 0.75 multiplying both by 100 so q cubed= 10800 over 75 when we divide 10800 with 75 we get q cubed=144 then we subtract 144 from each side consider q cubed - 144 rewrite it as q cubed minus 12 cubed the squares can be factored by a cubed and b cubed = ( a - b )(a+b)
So then it’s (q -12) (q+12) = 0 to find solution you gotta solve q - 12 = 0 and q+ 12=0

A circle is never a square?
Nookie1986 [14]

Answer:

never

A jar has 32 marbles. Some are blue and the rest are green. There are three times as many green marbles as blue. How many green
ella [17]

Answer: 24

Step-by-step explanation:

Number of marbles in jar = 32

Let blue marbles be represented by b.

Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b

We then add them together. This will be:

3b + b = 32

4b = 32

b = 32/4

b = 8

There are 8 blue marbles

Since green is 3× blue. Therefore,

Green = 8 × 3 = 24 marbles

The perimeter of a rectangle is 70 cm. The ratio of length to width is 2:5. Find the length and width of the rectangle.
olya-2409 [2.1K]

Answer:

length = 10 cm; width = 25 cm

Step-by-step explanation:

Let's call the length 2x and the width 5x. Since perimeter can be calculated by multiplying the sum of the length and width by 2 we can write:

2 * (2x + 5x) = 70

2 * (7x) = 70

7x = 35

x = 5 which means the length is 2 * 5 = 10 and the width is 5 * 5 = 25.

The cost of a lack has increased by 30% to £65. Work out the original price
Sveta_85 [38]
Cost of lack increased by 30%

new cost of lack will be = 100% + 30% = 130%

We are given that new cost = £65

Thus 130% of original cost = 65

100% of original cost = 65 × 100/130 = £50

Thus original price was £50
