B. 00:00 The exponent would be positive because the original number is greater than one. C. 00:00 The exponent would be negative because the original number is less than one. D. 00:00 The exponent would be positive because the original number is less than one.
Answers
Answer:
The exponent would be negative because the original number is less than one.
Step-by-step explanation:
The given number is 0.0009763. We can write it as a single digit times a power of ten.
There are 3 zeroes after decimal and then 9 comes. As the original number is less than. It means we can write it as follows :
[tex]0.0009763=9.76\times 10^{-4}[/tex]
The exponent is negative here. The correct option is (c) "The exponent would be negative because the original number is less than one"

The weight of a stack of standard 8.5x11 copier paper vs. number of sheets of paper.
Answers
Answer:
Proportional
Step-by-step explanation:
This is proportional because the weight of the stack of paper directly corresponds to the number of sheets of paper. The amount of paper affects the weight. It's just like saying that adding one extra person in an elevator will make the weight of the elevator more.
A bakery has 72 half gallons of milk. It takes 123 cups of milk to make a cake. Note that 1 cup = 18 half gallon = 0.125 half gallon. How many cakes can the bakery make?
Answers
Answer:
Total production= 4.68 cakes = 4 cakes
Step-by-step explanation:
Giving the following information:
A bakery has 72 half gallons of milk.
It takes 123 cups of milk to make a cake.
1 cup = 0.125 half gallon
First, we need to calculate the number of half gallons for each cake:
Half gallons per cake= 123*0.125= 15.375 half gallons
Now, for 72 half gallons:
Total production= 72/15.375
Total production= 4.68 cakes = 4 cakes

Kelli wants to sew trim around the sleeves and hem of a dance costume. She needs a piece of trim that is 8 1/8 inches long for the sleeves and a piece that is 40 5/8 inches long for the hem. If the package contains 5 feet of trim, how much trim will she have left after making the costume.
Answers
Answer:
0.9375 feet of trim
Step-by-step explanation:
Step 1
We find the total number of inches used
We are told : She needs a piece of trim that is 8 1/8 inches long for the sleeves and a piece that is 40 5/8 inches long for the hem.
Hence, the total = (8 1/8 + 40 5/8)inches = 48 3/4
= 48.75 inches
Step 2
We convert to feet
1 inch = 0.0833333 feet
48.75 inches = x
Cross Multiply = 48.75 × 0.00833333 feet
= 4.0625 feet
Hence, she would use 4.0625 feet of ribbon
If the package contains 5 feet of trim, how much trim will she have left after making the costume.
This is calculated as:
5 feet - 4.0625 feet
= 0.9375 feet of trim

Answers
Answer:
2x^2+2x−12 or (2x+6)*(x-2)
Step-by-step explanation:
Area: (2x+6)*(x-2)
now, we simplify.
(2x+6)*(x-2)=(2x+6)(x+(−2))
=(2x)(x)+(2x)(−2)+(6)(x)+(6)(−2)
=2x^2−4x+6x−12

The driving time varies inversely with the speed of the car if a certisn trip takes 40 min utes when you travel 50 miles per hour how many minutes would it take if u travel 40 miles per hour
Answers
Answer:
The value is [tex]t_2 = 50 \ minutes[/tex]
Step-by-step explanation:
From the question we are told that
The driving time varies inversely with the speed of the car
The amount of time a trip at a velocity of [tex]v_1 = 50 \ mph[/tex] takes is [tex]t_1 = 40[/tex]minutes
Let
v represent the velocity
while t represent the time
So
[tex]t \ \ \alpha \ \ \frac{1}{v}[/tex]
=> [tex]t \ \ = k \ \ \frac{1}{v}[/tex]
=> [tex]k = vt[/tex]
=> [tex]v_1 * t_1 = v_2 * t_2[/tex]
From the question we are given [tex]v_2 = 40 \ mph[/tex] and we are told to find [tex]t_2[/tex]
So
[tex]t_2 = \frac{v_1 * t_1}{v_2}[/tex]
=> [tex]t_2 = \frac{ 50 * 40}{40}[/tex]
=> [tex]t_2 = 50 \ minutes[/tex]

A local pizza shop has a membership program for frequent buyers. The membership costs $25 per month and members get a discounted price of $1.50 per slice of pizza. Aaliyah purchased a membership to this pizza shop. How much would Aaliyah have to pay the pizza shop if she bought 6 slices of pizza this month? What would be the monthly cost for xx slices of pizza?
Answers
Answer: $34
$26.5
Step-by-step explanation:
Membership cost per month = $25
Price of a slice of pizza for members= $1.50
How much would Aaliyah have
to pay the pizza shop if she bought 6 slices of pizza this month
Total cost of Aaliyah on 6 slices of pizza = membership cost per month + prices of 6 discounted pizza
= $25 + $1.50(6)
= $25 + $9
= $34
What would be the
monthly cost for a slices of pizza
Monthly cost of Aaliyah a slices of pizza = membership cost per month + price of 1 discounted pizza
= $25 + $1.5
= $26.5

The total amount y (in dollars) in your savings account after buying x video games is represented by y=90-10x. You have $40 in your account after buying video games. How many video games did you buy?
Answers
Explanation:
Step one) identify all variables.
> y = money in bank acc AFTER buying (x) video games.
Step two) y = $40
Step three) substitute
> 40 = 90 - 10x.
Step Four) solve for x
> subtract 90 both sides.
-50 = -10x
DIVIDE by -10 on both sides ( to isolated x)
This equals 5 = x
x is number of video games bought meaning >> 5 video games bought :))

There are 35 red beads on the bracelet. The number of green beads on the bracelet is 42. Kaleb says that means the ratio of the number of red beads to the number of green beads is 5: 7. Is Kaleb correct? Explain why or why not. (Use complete sentences!)
Answers
Answer:
No
Step-by-step explanation:
Ratios are the same as percentages or fractions. In this case there are 35 red beads for every 42 green beads on the bracelet. This means the ratio would be [tex]\frac{35}{42}[/tex] , which when put divided is 0.833 or 83.3%. Kaleb is stating that the ratio is 5:7 which would basically be [tex]\frac{5}{7}[/tex] which when divided is 0.71 or 71%. Therefore, since these percentages are different we can go ahead and say that Kaleb is not correct.

A computer randomly puts a point inside the rectangle. What is the probability
that the point does not land in triangle T?
Answers
Answer:
87.5%
Step-by-step explanation:
The area of the entire rectangle is 8 by 6,
8x6=48 so the area is 48 units^2.
The area of the triangle is A=1/2bh
A=1/2(2)(6)
A=1(6)
A=6 units^2
6/48=0.125
0.125=12.5%
You need to find the percent it will not land in the triangle, so subtract 12.5 from 100.
100-12.5=87.5
There is an 87.5% chance it will not land in the triangle
