Jonathan has a collection of 400 marbles. Blue makes up 17% of his collection,how many blue marbles does Jonathan have?

Yuki888 [10]

So percent means parts out of 100 so 17%=17/100
400 marbles
17% of 400=blue
'of' can be translated to multiply
17%=17/100
17/100 ties 400=6800/100=68
he has 68 blue marbles

Sherri got a new job as a teacher for the local school. Her rent is going to be 40% of her income, she will save 10% each month,

Xelga [282]

Answer:

The mistake she is making is that she is making less than she is spending

Step-by-step explanation:

Step 1: Determine her total income

Let her total income be x

Step 2: Determine amount of each expense

The amount of each expense can be expressed;

Amount of each expense=percentage of total expense×total income

a). Rent

percentage expense on rent=40%

total income=x

Amount of rent=(40/100)×x=0.4 x

b). Savings

percentage expense on savings=10%

Amount of savings=(10/100)×x=0.1 x

c). Fixed expenses

percentage fixed expense=40%

Amount of fixed expenses=(40/100)×x=0.4 x

d). Flexible expenses

percentage flexible expense=20%

Amount of flexible expenses=(20/100)×x=0.2 x

Step 3: Calculate total expenses

Total expenses=Amount of flexible expenses+fixed expenses+amount of savings+amount of rent

replacing;

Total expenses=(0.2 x+0.4 x+0.1 x+0.4 x)=1.1 x

Step 4: Get remaining amount of her income

Net income=(x-1.1 x)=-0.1 x

This means that her expenses exceed her income by -0.1 x. The mistake she is making is that she is making less than she is spending

Jon is making hamburgers for a church lunch. He has 42 and two thirds lbs of ground beef. How many one third pound hamburgers ca

lys-0071 [83]

Answer:

He can make 128 one third pound of hamburgers using all the ground beef.

Step-by-step explanation:

Given:

Jon is making hamburgers for a church lunch. He has 42 and two thirds lbs of ground beef.

Now, to find the number of one third pound hamburgers can he make using all the ground beef.

Pound of ground beef he has = $42\frac{2}{3} \ lbs.$

Pound of hamburgers he can make = $\frac{1}{3}$ .

Now, to get the number of hamburgers he can make by using all the ground beef we divide the quantity of ground beef by $\frac{1}{3}$ :

$\frac{128}{3} \div\frac{1}{3}$

As, the division changes into multiplication one of the fraction get reciprocals.

$=\frac{128}{3} \times \frac{3}{1}$

$=\frac{384}{3}$

$=128.$

Thus, 128 hamburgers he can make.

Therefore, he can make 128 one third pound of hamburgers using all the ground beef.
