A local grocery store sells oranges $1.15 per pound, tax included. A shopper buys 1.3 pounds of oranges from the store. Rounded to the nearest cent, how much does the shopper pay for the oranges?

Answers

Answer 1

the price for one pound is $1.15

to find the total cost you need to multiply the cost of one pound by the total weight of how much was bought

 they bought 1.3 pounds, so multiply 1.3 by 1.15 for the total cost

1.15 * 1.3 = 1.495 which rounds up to $1.50

the shopper paid $1.50

Solve for x.
a(5 - x) = bx - 8

Answers

Consider the given equation:

[tex]a(5-x)=bx-8[/tex]

We have to solve the given equation for the value of 'x', we get

We will use distributive property which states [tex]a(b+c) = ab+ ac[/tex]

[tex](a \times 5)+(a \times -x) = bx-8[/tex]

[tex]5a-ax = bx -8[/tex]

Equating the like terms and the constants, we get

[tex]5a+8= ax+bx[/tex]

Taking 'x' common from the RHS of the equation.

[tex]5a+8 = x(a+b)[/tex]

[tex]x = \frac{5a+8}{a+b}[/tex]

Therefore, the value of 'x' is [tex]x = \frac{5a+8}{a+b}[/tex].

The value of 'x' in equation a(5 - x) = bx - 8 is x=5a+8/(b+a).

Consider the given equation

a(5-1)=bx-8

We have to solve the given equation for the value of 'x', we get

We will use distributive property which states

What is the statement of the distributive property?

a(b+c)=ab+ac

5a-ax=bx-8

Equating the like terms and the constants, we get

5a+8=bx+ax

Taking 'x' common from the RHS of the equation.

5a+8=x(b+a)

x=5a+8/(b+a)

Therefore, the value of 'x' is x=5a+8/(b+a).

(02.02 LC) Choose the equation that could be used to find three consecutive integers whose sum is 36. (5 points) n + (n + 2) + (n + 4) = 36 n + (n + 1) + (n + 3) = 36 n + (n + 1) + (n + 2) = 36 n + (n − 1) + (n − 3) = 36

Answers

n + (n + 1) + (n + 2) = 36 Let's first create the equation ourselves and then see if it fits any of the available options. We want 3 consecutive integers that add up to 36. Let's use the value "n" to represent the first number in the sequence. n Now the next number will be n+1 and the third will be n+2. And since we want the sum, we get n + n + 1 + n + 2 = ? And finally, we want the sum to be 36, so our final equation is n + n + 1 + n + 2 = 36 With this equation in mind, let's look at the available choices. n + (n + 2) + (n + 4) = 36 Well, it has the 36 OK, but it has +2 and +4 where we have +1 and +2. So it won't fit and it's wrong. n + (n + 1) + (n + 3) = 36 Closer. Got the 36 and the +1. But it has +3 instead of +2, so not a fit either. n + (n + 1) + (n + 2) = 36 This looks good. Has a couple of extra parenthesis, but they don't affect the final answer and it has the +1, +2 and the 36. This one is correct. n + (n â’ 1) + (n â’ 3) = 36 Hmm. The n - 1 has a possibility. Perhaps they want n to be the middle of the 3 numbers to add. If that's the case, then the other number should be n+1 which it isn't. Maybe they want the n to be the last number. If that's the case, then the third number should be n-2. But that doesn't work either. So this equation won't work. So of the 4 choices, the only answer that works is "n + (n + 1) + (n + 2) = 36"

Isabelle bought 12 bottles of water at $2 each

Answers

Isabelle bought 4 bottles of water.

Here's how to solve for the number of bottles of water Isabelle bought:

Let x be the number of bottles of water Isabelle bought.

The total cost of the water bottles is 2x dollars (2 dollars per bottle * x bottles).

We know the total cost was $21, so we can set up an equation:

Total cost = Cost of water bottles + Cost of pizza

21 = 2x + 13

Now, solve for x:

Subtract 13 from both sides: 21 - 13 = 2x + 13 - 13

Simplify: 8 = 2x

Divide both sides by 2: 8 / 2 = 2x / 2

Get the final answer: x = 4

Therefore, Isabelle bought 4 bottles of water.

Complete question:

Jacki plans to pay for the down payment of a new car with her credit card. The annual interest rate for her credit card is 17%. The following expression represents the balance of the credit card, in dollars, after t years. 2,250(1.17)^t
Write an exponential expression in the form (b)c that reveals the monthly interest rate of Jacki's credit card. Round any decimals to the nearest thousandth.

Answers

Given that the annual interest rate of Jacki's credit card is 17%, then the exponential expression that reveals the monthly interest rate of Jacki's credit card is given by:

[tex]2,250\left(1+\frac{0.17}{12}\right)^{12t}=2,250(1+0.014)^{12t} \\ \\ =\bold{2,250(1.014)^{12t}}[/tex]

Answer:

[tex]A=2250(1.014)^{12t}[/tex] is the exponential expression.

Step-by-step explanation:

The expression which represents the balance of credit card, in dollars, after t years is

[tex]A=2250(1+\frac{0.17}{12})^{12t}[/tex]

Where rate of interest is 17% and amount spent is $2250.

Since 17% interest is the annual interest and we have done the expression in the form of monthly compounding.

So the expression will be

[tex]A=A_{0}[1+.014]^{12t}[/tex]

[tex]A=A_{0}(1.014)^{12t}[/tex]

[tex]A=2250(1.014)^{12t}[/tex]

The ratio of 3 scoops of hot cocoa mix  to 10 miniature marshmallows and 8 ounces of water.  is 3:10

What is Ratio?

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. Similarly, the ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.

Given :-

amount of cocoa scoops = 3

amount of miniature marshmallows used = 10

We have to find out the Ratio of scoops of hot cocoa to miniature marshmallows:

First  we will simplify the term if there is any

Scoops of hot cocoa / miniature marshmallows = 3/10

Since, the simplification is already been done

Thus, the ratio will be:

Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those surveyed do not want a new mall. How many people did Annette survey?

Answers

Answer:

480 people

Step-by-step explanation:

First you would divide 180 by 37.5,

180 divided by 37.5 = 4.8

Then you multiply 4.8 with 100

4.8 times 100 =480

Therefore, Annette surveyed 480 people

We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.

We will find that the number of people that Annette survey is 480.

To get the solution:

Let's assume that she surveyed a total of X people.

Then we can write the equivalence:

100% = X

We know that the 37.5% is equivalent to 180 people, then we can write:

37.5% = 180

The two equations are:

100% = X

37.5% = 180

Now we can take the quotient between these two equations to get:

(100%/37.5%) = X/180

Solving for X we get:

(100%/37.5%)*180 = X = 480

So the total number of people surveyed is 480.

Dawn is an avid reader and reads 30 pages every 8 days. Part A How many pages per day does Dawn read? Part B At this rate, Dawn takes 28 days to read her favorite novel. How many pages does the novel have?

Answers

Final answer:

Dawn reads 3.75 pages per day. At this rate, a favorite novel that she completes in 28 days contains 105 pages.

Explanation:

This is a problem of rates and proportions.

Part A: To find out how many pages Dawn reads in a day, we divide the total pages she reads in 8 days by the number of days. Going by the data, if she reads 30 pages in 8 days, then, using the proportion, Dawn reads 30/8 = 3.75 pages per day.

Part B: To find out how many pages Dawn's favorite novel has, we multiply the rate (pages/day) by the number of days. So, if she takes 28 days to read the novel at a rate of 3.75 pages per day, then by using the multiplication principle, the novel has 3.75 pages/day * 28 days = 105 pages.

Two right triangles, PQR and MNO. For triangle PQR, angle Q is thirty degrees. For triangle MNO, angle N is forty-five degrees.

Answers

Given that the two trianglea are right angles, this means that one of the angles is 90 degrees.

If one on the angles of triangle PQR is 30 degrees, then the third angle will be 60 degres.

Thus, the three angles of triangle PQR are: 90, 30, 60

If one on the angles of triangle MNO is 45 degrees, then the third angle will be 45 degres.

Thus, the three angles of triangle MNO are: 90, 45, 45

For two triangles to be similar, their angles has to equal.

Therefore, triangles PQR and MNO are not similar.
The triangles are not similar. For triangle PQR to be similar to triangle MNO, each angle would have to be congruent. The two triangles only have a 90 degree angle in common. Triangle PQR has 90, 30, and 60 degree angles while triangle MNO has 90, 45, and 45 degree angles.
