This is calculated as:




The correct answer is A!
A. 1/2 is equal to .5 so multiply 2,000 by .5 and you’ll get $1000. She spends $900 on rent. Since $900 is less than $1000 she is not spending more than half of her income on rent. There for this statement is False
B. If you do 2,000 multipled by .15 (which equals 15%) then you’ll get $300 and that’s how much she spends on savings. So this statement is true.
C. 1/4 = .25 so if you do 2,000 multiplied by .25 you’ll end up with $500. The total cost of utilities, cable and groceries ( 120 + 80 + 320 ) = $520 and since $500 is less than $520 then she is spending more than 1/4 of her income on those expenses. Which makes this statement true.
D. 14% is = .14 so if you do 2,000 multiplied by .14 you’ll get $280. The total of cell phone and other expenses ( 100 + 180 ) = $280 so that is true.
Answer:
w=3/5 or w=-5
Step-by-step explanation:
5w^2+22w=15
5w^2+22w-15=0 (quadratic equation)
a=5, b=22, c=-15
w1,2 =(-b+-sqrt(b^2-4ac))/2a
w1,2 =(-22+-sqrt(22^2-4*5*(-15))/2*5
w1,2 =(-22+-sqrt(484+300))/10
w1,2=(-22+-sqrt(784))/10
w1,2=(-22+-28)/10
w1=(-22+28)/10, w2=(-22-28)/10
w1=6/10, w2=-50/10
w1=3/5, w2=-5
Answer:
The number of students who received the paint=5 students
Step-by-step explanation:
Step 1: Determine amount given to each student
Quantity per student=1/7 gallon per student
Step 2: Determine the total amount of paint Mrs. Jennings had
The total quantity of paint Mrs. Jennings is:
Initial quantity of paint=5/7 gallon
Step 3: Calculate number of students who received the paint
The number of students who received the paint can be expressed as;
Initial quantity of paint=Quantity per student×number of students
where;
Initial quantity of paint=5/7 gallons
Quantity per student=1/7 gallons
number of students=n
replacing;
5/7=(1/7)×n
n=(5/7)×7
n=5
The number of students who received the paint=5 students
