First, determine the blueberries needed for only 1/3 cup of jam
for 1/3 cup = for 2/3 cup ÷ 2
for 1/3 cup = 3/4 ÷ 2
for 1/3 cup = 3/4 × 1/2
for 1/3 cup = 3/8
We need 3/8 pounds of blueberries for 1/3 cup of jam

Second, determine the blueberries needed for a cup of jam
a cup means 3/3 cup, so the blueberries needed will be
for 3/3 cup = for 1/3 cup × 3
for 3/3 cup = 3/8 × 3
for 3/3 cup = 9/8

Change it to mixed fraction
9/8 = 1 1/8
For a cup of jam we need 1 1/8 pounds of blueberries
The answer is first option

Use synthetic substitution to evaluate the polynomial P(x) = x^3-3x^2+4x-7 for x=3
Zina [86]

Answer:

\frac{x^3-3x^2+4x-7}{x-3} =(x^2+4)+\frac{5}{x-3}

Step-by-step explanation:

We are given polynomial as

P(x)=x^3-3x^2+4x-7

and it is divided by x=3 or x-3

we can use synthetic division

so, we got

Remainder =5

Quotient is

=x^2+0x+4

=x^2+4

we can write as

\frac{x^3-3x^2+4x-7}{x-3} =(x^2+4)+\frac{5}{x-3}

A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level, how long will
navik [9.2K]

Answer

Find out the how long will it take the submarine to descend to the ocean floor

To proof

Formula

r = \frac{d}{t}

where  d  =  distance traveled (or descended),

r  = rate of travel , t  = time

As given

A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level .

put all the values in the above formula

2.6 = \frac{6.24}{t}

t = \frac{6.24}{2.6}

t = 2.4 hour

it take 2.4 hours the submarine to descend to the ocean floor .

Hence proved
