Answer:
19 Slices.
Step-by-step explanation:
The number number of Pizzas = 3
Each Pizza had = 8 Slices
<u>Determining the Total number of Slices:</u>
Total no. of slices =Pizzas × Slices per Pizza
Total no. of Slices = 24
<u>Determining the number of slices Consumed by 5th Grade Teachers :</u>
Total no. of slices Consumed by the Teachers = 5 × 1
Total no. of slices Consumed by the Teachers = 5
<u>Total number of slices Consumed by the students:</u>
Total no. of slices Consumed by the students = Total slices - Slices consumed by teachers.
Total no. of slices Consumed by the students= 24 - 5
Total no. of slices Consumed by the students= 19
Answer:
$27 per week.
Step-by-step explanation:
Multiply:
$2.65 x 8 (twice per day)= $21.20
$1.45 x 4 (once oer day)=$5.80
Add those together to get $27 per week.
Answer:
8.1
Step-by-step explanation:
The perimeter of a circle means the circumference. In this question it says the perimeter of a quarter circle is 17.85 miles and we want to find the quarter circle’s radius.
We know that the perimeter of the quarter circle is 17.85 which means that the 2 radii and the circumference of the circle sum to 17.85.
The formula to work out the perimeter of a quarter circle is 
. We can form an equation to work out the radius so,
= 17.85
→ Multiply everything by 2 to get rid of the fraction
4r + π = 35.7
→ Minus π from both sides to isolate 4r
4r = 32.55840735
→ Divide both sides by 4 to isolate 4
r = 8.139601837
The radius of the quarter circle is 8.1 miles to 1 decimal place
Answer:
y= -5x - 21
Step-by-step explanation:
parallel lines have the same slope, so you know the slope.
you need to use the point slope formula y-y1=m(x-x1)
with this equation, this looks like y - -1 =- 5(x - -4)
double negatives are positives, so to keep this easier on the eyes, let's make it y + 1= -5(x + 4)
distribute the -5. you should get y + 1 = -5x - 20
subtract 1 to move it from the left side to the right and you get your answer!
y = -5x - 21
