If Keenan makes a basket with 6 apples, what is the ratio of apples to oranges written as a fraction?

Answers

the answer i believe is 6:4

The ratio of apples to oranges, written as a fraction If Keenan makes a basket with 6 apples, is 5 / 4.

What is a fraction?

Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions are first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.

Given:

For every 4 oranges, there are 5 apples,

Keenan makes a basket with 6 apples,

Calculate the number of oranges as shown below,

The number of oranges = 4 / 5 × 6 = 24 / 5

Calculate the fraction of apples to oranges as shown below,

Ratio = The total number of apples / The number of oranges

Ratio = 6 / 24 / 5

Ratio = 30 / 24

Ratio = 5 / 4

Thus, the ratio is 5 / 4.

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary.
(Please show your work)

Answers

Answer:

12

Step-by-step explanation:

Since this is a right angle triangle, and we have two lengths already found, we can use pythagoras to find x.

We know that

a²+b²=c²

Where a, and b are the smaller lengths (the adjacent and opposite), and C is always the longest one (the hypotenuse).

We want to find x, which in this case is c. So,

to solve for c, we get

c=[tex]\sqrt{a^2+b^2 }[/tex]

So, after plugging in the values, we get

[tex]c=\sqrt{10.6^2+6.1^2}[/tex]

[tex]c=12.23\\\\=12 (rounded)[/tex]

4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4

36x + 16 = 36x - 7  ( subtract 16 from both sides )

36x = 36x - 23 ( subtract 36x from both sides )

0 = - 23 ← False statement
