It -10 Fahrenheit in Minneapolis then in Chicago select all the values they could represent the temperature of Minneapolis

Answers

High °F Low °F City High °C Low °C
84 64 Chicago, Illinois 29 18

Final answer:

If it's -10 Fahrenheit in Minneapolis and a cold front drops the temperature by 40 degrees, the new temperature would be -50 Fahrenheit.

Explanation:

If the temperature is -10 Fahrenheit in Minneapolis, and a cold front drops the temperature by 40.0 Fahrenheit degrees, we need to calculate the new temperature. This would mean subtracting 40 degrees from the current temperature of -10 degrees.

Starting with -10, we subtract 40 degrees:
-10 − 40 = -50

Therefore, the value that could represent the temperature in Minneapolis after the cold front is -50 Fahrenheit.

Store ABC sells 8 lbs. of oranges for $6.00. Store XYZ sells 14 lbs. or oranges for $11.20. Which store is less expensive, and by how much per pound? 1. ABC is less expensive by $.50 per pound 2. XYZ is less expensive by $.50 per pound 3. ABC is less expensive by $.05 per pound 4. XYZ is less expensive by $.05 per pound

Answers

ABC-
8:6

XYZ-
14:11.20

ABC (unit rate)-
Divide both sides by 8...
1:0.75

XYZ (unit rate)-
Divide both sides by 14...
1:0.80

ABC is less, 0.80>0.75. The difference between the two is 0.05; 0.80-0.75=0.05.

So the answer is:
3. ABC is less expensive by $0.05 per pound.

Amery drives 50 miles in one hour. How many miles does he drive in 2.25 hours?

Answers

So if he drives 50 miles in 1 hour, then he must drive 100 miles in 2 hours. 0.25 is another way of writing 1/4, and to find 1/4 you divide by 4, so 50 ÷ 4 = 12.5 miles. Then you can add this to 100 and get your answer as 112.5 miles.
If you have a calculator, or if you're allowed a calculator, then a simpler way is to just do 2.25 × 50 = 112.5

A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = - 16t^2 + 576t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit.

Answers

We have to find te vertex of this parabola.
Given a square function:
F(x)=ax²+bx+c
The vertex of this parabola will be the point (-b/2a, f(-b/2a)

In this case:
h(t)=-16t²+576t
a=-16
b=576
-b/2a=-576/-32=18
h(18)=-16(18)²+576(18)=-5184+10368=5184
The vertex will be: (18, 5184)

Because a is negative we have a maximum, if a were positive we have a minimum.
Then we have a minimum at t=18 s; and the maximum heigth would be 5184 m

Answer: The projectile take to reach its maximum heigth in 18 s, and the maximum height would be 5184 m.

h(t) = -16t^2 + 640t This is a "quadratic" (think parabola) and because the coefficient associated with the t^2 term is NEGATIVE, we know it opens downward. Therefore, the vertex is the maximum. . The time (secs) when it reaches the max is: t = -b/(2a) t = -640/(2(-16)) t = -640/(-32) t = 20 seconds

A geologist visits 60 volcanoes in Alaska and California. 15% of the volcanoes are in California. How many volcanoes did the geologist visit in California and how many are in Alaska?

Answers

To solve this, first find out how many volcanoes were in California. As 15% were in California, you can multiply the total number of volcanoes by the percent IN DECIMAL FORM. To convert it to decimal form, divide it by 100, so 15/100=.15. Now multiply by your total to get the number of volcanoes in California (C), C=60*.15=9 volcanoes in California. To get the volcanoes in Alaska, yous subtract your volcanoes in California from your total, so 60-9=51 volcanoes in Alaska.

Write two different ways to find the difference for 12 - 3

Answers

Hey there! Hello!

There are a few different ways you could represent subtraction. One of which is by using a circle or other shape to represent each number in your problem, which is 12, then cross out the number you want to take away. You can see this in the higher portion of my attachment.

Another method you could use is a number line. In the lower portion of the attachment, you can see how I start at 12 then move towards zero three times.

In both instances, you can see that 12 – 3 is equal to nine.

Hope this helped you out! Feel free to ask any additional questions if you have any. :-)

Final answer:

There are two different ways to find the difference for 12 - 3: using the subtraction method or the addition method. Both methods will give you the same result of 9.

Explanation:

There are two different ways to find the difference for 12 - 3:

Subtraction Method: Subtract the smaller number (in this case, 3) from the larger number (in this case, 12).
12 - 3 = 9Addition Method: Start with the smaller number (3) and keep adding until you reach the larger number (12). Count the number of steps or additions it takes to reach 12.
3 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 9

a phone company charges a base fee of $10.00 per month

Answers

Not sure what the question is but ill try an explain. $10.00 a month means $1200.00 a year. if you ever need to find out the amount it will cost for x months then this is the equation M = $10(x) M is the total amount it costs, 10 is the 10 dollars you pay every month and (x) is how many months. so lets say you need to know how much it will cost for 3 months, then all you do is plug 3 into the x's spot and solve the equation.

Isaac made 2 quarts and 1 cup of cupcake batter. If 6 ounces of batter make one cupcake, and Isaac is making 10 cupcakes, how much batter will be left over?

Answers

Answer:

12.115 ounces of batter

Step-by-step explanation:

Isaac made 2 quarts and 1 cup of cupcake batter.

We will convert the amount into ounces

1 quart = 32 ounces

2 quarts = 32 × 2 = 64 ounces

1 cup = 8.115 ounces

∴ 2 quarts and 1 cup = 64 + 8.115 = 72.115 ounces

To make one cupcake Isaac needs the amount of batter = 6 ounces

He is making 10 cupcakes, so he would be needed = 10 × 6 = 60 ounces

He has 72.115 ounces of batter and he would be needed 60 ounces

The left over batter = 72.115 - 60 = 12.115 ounces.

12.115 ounces batter would be left over.

-84(-3 - 5p)=-176 help please

Answers

-84 = 3(5n + 2)

Multiply everything in the parenthesis.

-84 = 3(5n + 2)
3*5n + 3*2

-84 = 15n + 6
Subtract 6 from both sides

-84 = 15n + 6
-6 -6

-90 = 15n
Divide 15 from both sides

-90 = 15n
--------------
15 15

-6 = n

-6 is your answer.

First divide both sides by the coefficient, -84, to leave (-3 - 5p) = -176/-84 = 176/84

Then add 3 to both sides, which gives -5p = (176/84) + 3 = 62/21 + 3

Now divide both sides by the coefficient -5:

p = (125/21)/-5 = -25/21

Heather works in a clothes shop where she earns a commission of 5% and no weekly salary. What will heather's weekly sales have to be for her to earn $375.00 in a week?

Answers

Heather's weekly sales must be $7500 in order to earn $375.00 in weekly salary.

What is the commission?A commission is a fee charged by a broker or investment advisor for handling a client's securities purchases and sales or for providing financial advice.There are significant distinctions between commissions and fees, at least in the context of professional advisors in the financial services sector.A commission-based advisor or broker earns money by selling investment products such as mutual funds and annuities as well as engaging in financial transactions with clients' funds.

Therefore,

Commission / commission rate = sale

Commission = $ 375.00 in a week

Commission rate = 5%

∴ 0.05

Then simplifying we get,

⇒ 375/0.05

= 7,500

Hence, Heather's weekly sales have to be $7500 to earn $375.00 in a weekly salary.
