Step-by-step explanation:

Prime factors of :

• 80 = 2 × 2 × 2 × 2 × 5

• x² = x × x

• y = y

• 80x²y = 2 × 2 × 2 × 2 × 5 × x × x × y

Prime factors of :

• 56 = 2 × 2 × 2 × 7

• x³ = x × x × x

• y² = y × y × y

• 56x³y² = 2 × 2 × 2 × 7 × x × x × x × y × y

Prime factors of :

• 81 = 3 × 3 × 3 × 3

• x = x

• y² = y × y

• 81xy² = 3 × 3 × 3 × 3 × x × y × y

A bakery used 38 pounds of flour to make French bread and

fomenos

Answer:

since we are not given the options, I will write down a few equations that represent the number of French bread loaves and bagels:

a = number of loaves of French bread
b = number of bagels
available amount of flour = 38

2a + b ≤ 38

2a ≤ 38 - b

a ≤ (38 - b) / 2

a ≤ 19 - 0.5b

b ≤ 38 - 2a

b ≤ 2(19 - a)

Hopefully one of these equations is one of the choices given to you.

How much of a spice that is 30% salt should be added to 175 ounces of a spice that is 65% salt in order to make a spice that is

klasskru [66]

$\bf \begin{array}{lccclll}
&amount&concentration&
\begin{array}{llll}
concentrated\\
amount
\end{array}\\
&-----&-------&-------\\
\textit{30\% spice}&x&0.30&0.30x\\
\textit{65\% spice}&175&0.65&(175)(0.65)\\
-----&-----&-------&-------\\
mixture&x+175&0.50&(x+175)(0.50)
\end{array}$

so.. as you can see, we use the decimal notation for the percentages... 65% is just 65/100 and 50% is just 50/100 and so on

so.. whatever the salted amounts are, we know they'll add up to (x+175)(0.50)

thus (0.30x) + (175)(0.65) = (x+175)(0.50)

solve for "x"

A company that creates steering wheels for cars found that 2 of the steering wheels manufactured each hour yesterday were defect

Ymorist [56]

2 steering wheels manufactured each hour were defected
There were 50 steering wheels manufactured per hour
The fraction is $\frac{2}{50}$
Divide 2, which is the numerator by 50, which is the denominator
2÷50=.04
To change any decimal into a fraction, multiply by 100
The multiply .04 by 100 to change into a percentage
.04×100=4.⇒4%
4% is the percentage of defective steering wheels
