Answer:
A
Step-by-step explanation:
2(4)+4(3) =20
8+12=20 yes
--------------------------
2(4)+2(3)=14
8+6=14 yes
Answer:
2 burgers and 4 drinks= $20 while 2 burgers and 2 drinks=$14
if the burger cost was $2 and the drink cost was $4, Emily would've spent $20 while Deja would've spent $12, so B's wrong
if the burger cost was $5 and the drink cost was $3, Emily would've spent $22, so C's incorrect, too
if the burger cost was $3 and the drink cost was $2, Emily would've spent $14 and Deja would've spent $10 so D's false as well
Therefore A's correct
Step-by-step explanation:
the burger cost is $4 and the drink cost is $3, Emily spent $20 and Deja spent $14
t=total, bc= burger cost, dc=drink cost
Emily's Equation:
t= 2(bc)+4(dc)
t=2(4)+4(3)
t=8+12
t=20
20=20
Deja's Equation
t=2(bc)+2(dc)
t=2(4)+2(3)
t=8+6
t=14
14=14
what do you multiply to get 201.25 and add to get 58
9514 1404 393
Answer:
29 +√639.7529 -√639.75Step-by-step explanation:
If we let x represent one of the numbers, then you want ...
x(58 -x) = 201.25
x² -58x +201.25 = 0 . . . . . put in standard form
(x² -58x +29²) +201.25 -29² = 0 . . . . complete the square
(x -29)² -639.75 = 0
x -29 = ±√639.75 . . . . . add 639.75 and take the square root
x = 29 ±√639.75 . . . . . . add 29
The two numbers of interest are ...
29 +√639.75 ≈ 54.2933
29 -√639.75 ≈ 3.7067

You're throwing a party, and you ordered 15 pizzas for your guests. Your total came to
$97.50. What was your unit cost per pizza?
A.$6.50 per pizza
B.$4.95 per pizza
C.$7.25 per pizza
D.$5.75 per pizza
Answer:
A
Step-by-step explanation:
97.5 / 15 = 6.5
The unit cost is $6.50 per pizza
What is the cost per unit in math?The "Unit Price" (or "unit cost") tells you the cost per liter, per kilogram, per pound, etc. of what you want to buy. How do I calculate cost per unit?To calculate the cost per unit, add all of your fixed costs and all of your variable costs together and then divide this by the total amount of units you produced during that time period.Based on the given conditions,
formulate: $97.50 ÷ 15
Convert decimal to fraction: 975÷10÷15
Divide a fraction by multiplying its reciprocal : [tex]\frac{975}{10}[/tex] ×[tex]\frac{1}{15}[/tex]
Cross out the common factor: [tex]\frac{65}{10}[/tex]
Cross out the common factor: [tex]\frac{13}{2}[/tex]
Per cost pizza : [tex]6.5[/tex] or [tex]6\frac{1}{2}[/tex]
Hence , throwing a party , ordered 15 pizza for guest and total value of pizza is $97.50 and the cost of one per pizza is $ 6.5 .

2(13 + x) ≤ 5413 + x ≤ 27x ≤ 27 - 13x ≤ 14 ftA canary has a heart rate of about 17 beats per second. How does the canary's heart rate compare to the bat's heart rate? Explain. (Remember, there are 60 seconds in a minute.)
Answer:
A canary's heart beats around 1,000 times per minute or 16.67 times per second. A canary is a very small bird whose heart beats more than twelve times faster than yours.
While a bat's heart beats between 200 to 1,000 times per minute. That means that while the bat is flying, its heart beats at the same rate as a canary's. But when the bat is resting, its heart beats is reduced by 5 times to "only" 200 beats per minute or 3.33 beats per second.
