Factor the expression: 20b - 16

2 answers:

6 0

When factoring this expression 20b-16, find the GCF (greatest common factor) among both terms. For this case, it is 4 which is the GCF. Therefore,

20b - 15 is equal to 4(5b - 4)

The factors of the expression are 4 and 5b-4.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

First, solve 3/4 × 4 using repeated addition. Then, solve 4 × 3/4 using multiplication and division. Hint: The answer should be

Ludmilka [50]

Step-by-step explanation:

Repeated Addition:

3/4 +3/4 +3/4 +3/4 = 12/4 = 3

The denomenator will stay the same (4). So all you need to do is add the numerator (top. number in the fracton, 3)

It is the same logic as a basic multiplication problem using reapeted additon

(see example below:)

10 * 5 = 50

10 +10 +10 +10 +10 = 50

Multiplication:

4 * 3/4 = 12/4 = 3

You should not multiply the denomerator. You should only multiply the numerator. So you multiply 4 times 3 and get 12. So, you should get 12/4.

I apologize for my bad spelling.

Oil leaked from a tank at a rate of r(t) liters per hour. the rate decreased as time passed, and values of the rate at two hour

Galina-37 [17]

The given data is
t, h: 0 2 4 6 8 10
r(t), L/h: 8.6 7.9 6.8 6.4 5.7 5.3

The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.

The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.

The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L

The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L

Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L

Maya makes trail mix by combining 1/3 cup of mixed nuts, 1/4 cup of dried fruit, 1/6 cup of chocolate morsels. What is the total

Vaselesa [24]

Answer:

The total amount of trial mix made by Maya is $\frac{9}{12}\ \ \ Or\ \frac{3}{4}$ .

Step-by-step explanation:

Given,

Amount of mixed nuts = $\frac{1}{3}\ cup$

Amount of dry fruits = $\frac{1}{4}\ cup$

Amount of chocolate morsels = $\frac{1}{6}\ cup$

We have to find out the total amount of trial mix made by Maya.

Solution,

Total amount of trial mix is the sum of amount of mixed nuts, amount of dried fruit and amount of chocolate morsels.

So we can frame the above sentence in equation form as;

Total amount of trial mix = Amount of mixed nuts + Amount of dry fruits + Amount of chocolate morsels

On putting the given values, we get;

Total amount of trial mix = $\frac{1}{3}+\frac{1}{4}+\frac{1}{6}$

Here we have to add the fractions.

For this we will make the denominator same.

Total amount of trial mix = $\frac{1\times4}{3\times4}+\frac{1\times3}{4\times3}+\frac{1\times2}{6\times2}=\frac{4}{12}+\frac{3}{12}+\frac{2}{12}=\frac{9}{12}\ \ \ Or\ \frac{3}{4}$

Hence The total amount of trial mix made by Maya is $\frac{9}{12}\ \ \ Or\ \frac{3}{4}$ .
