Answer:

$0.10 less

Step-by-step explanation:

First you need to find how much for one fluid ounce, so for Brand X you would divide 3.25 by 5 to get 0.65 and for Brand Y 6.00 divided by 8 to get 0.75. Now you know how much for 1 ounce of each brand so next you just have to subtract 0.65 (Brand X) from 0.75 (Brand Y) to get that Brand X costs $0.10 less than brand y

Answer:

No

Step-by-step explanation:

Given

Quadrilateral A: 2,3,5 and 6

Quadrilateral B: 4,5, 8 and 10

Required

Determine if one is a scale of another

To do that, we have to divide the corresponding lengths to give ratio.

Considering Side of A = 2 and Side of B = 4

[tex]Ratio = \frac{B}{A}[/tex]

[tex]Ratio = \frac{4}{2}[/tex]

[tex]Ratio = 2[/tex]

Considering Side of A = 3 and Side of B = 5

[tex]Ratio = \frac{B}{A}[/tex]

[tex]Ratio = \frac{5}{3}[/tex]

[tex]Ratio = 1.67[/tex]

There's no need to check further, since the two ratios calculated so far do not have the same value;

Hence, one quadrilateral is not a scale of the other

Answer:

0.60 m is total cost paid per mile

Step-by-step explanation:

Given:

Cost of renting a scooter = $25

Extra cost = $0.60 per mile

Total cost = $43.20

Find:

Meaning of 0.60 m

Computation:

25 + 0.60 m = 43.20

0.60 m = 43.20 - 25

0.60 m = 18.2

m = 30.33 mile

So,

0.60 m is total cost paid per mile

Answer:

  (a) more

  (b) less

  (c) more

  (d) greater

  (e) Left to right: Susan, George, Antonio, Maria

Step-by-step explanation:

When a point total is lower, more points are needed to stay in the game.

__

(a) Maria's total is less than -30, so she needs more than 30 to stay in the game. Phone #4 is the only one indicating a need of more than 30, so it is Maria's.

__

(b) Susan's total is greater than -25, so she needs less than 25* to stay in the game. Phone #1 is the only one indicating a need of less than 25, so it is Susan's.

__

(c) George's point total is lower than Susan's, so he needs more points than Susan. Susan's phone indicates she needs 20 points. Since George needs 5 more points, his is phone #2.

__

(d) Antonio needs 15 fewer points than Maria, so his total is more than Maria's total. Maria's phone indicates she needs 45 points, so Antonio only needs 30 points. His is phone #3.

__

(e) Susan needs 20, George needs 25, Antonio needs 30, Maria needs 45.

_____

* If we assume whole numbers of points, a total of "greater than -25" might be a total of -24. To bring the score to a positive value (1), exactly 25 points might be needed. That is, there is some ambiguity in part (b) in that Susan might need less than or equal to 25 points. Susan's phone could be either the first or the second.

The problem is poorly worded. The answer choices above are consistent with the problem statement overall.

Answer:

$345

Step-by-step explanation:

Cp= $300

MP= 115%×$300

=$345

Answer: C: Expression B and D

Step-by-step explanation:

Say the item is $100. 20% of 100 is equal to 100 (20/100)

When you simplify, it equals 20. So 20% of 100 is 20. This $20 is the amount of discount you receive.

So you have to subtract $20 from the $100 to find the sale price. The sale price is $80.

Now plug in 100 for p in each equation. The equation that equals 80 is the answer.

Only equation B and D equals 80 when 100 is plugged in.

Answer:

The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles

Step-by-step explanation:

Average speed = 400 miles per hour

Distance = 400t

t= 5

Total distance = 400t at t hours

Total distance when t = 5 hours

Total distance travelled = 400t

= 400 × 5

= 2,000 miles

Total distance travelled = 2,000 miles

The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles

Answer:

41

Step-by-step explanation:

You are going up by 4 for every term. So, for the 13th term, you're going up by 4*13= 52.

However, -7 is a term itself. -7 is the 1st term. If you added 52 to -7, that would be the 14th term! So, we will subtract 4 when we add 52 to -7.

-7+52=45

45-4=41

The answer is 41!

Hope this helps!

Answer:

D

Step-by-step explanation:

So first, we can see that this is an arithmetic sequence since each subsequent value is 4 greater than the previous one.

To find the value of the 13th term, we can construct an explicit formula for the sequence. Recall that an explicit formula of an arithmetic sequence has the following format:

[tex]x_n=a+d(n-1)[/tex]

Where n is the nth term, a is the initial term, and d is the common difference.

So, we already know that a is -7 the initial term. And also, every term is +4 than the previous one. Thus, the common difference is 4.

Plugging in all into the equation, we have:

[tex]x_n=-7+4(d-1)[/tex]

So, to find the 13th term, use 13 for n:

[tex]x_{13}=-7+4(13-1)\\x_{13}=-7+4(12)[/tex]

Simplify:

[tex]x_{13}=-7+48\\x_{13}=41[/tex]

So, the 13th term is 41.

The answer is D.

Answer:

Part A) = D) 13.33 m/sec

Part B) = A) Deer wins by 2.08 seconds

Step-by-step explanation:

Part A)

From the question in Part A, we know that, the White-tailed deer can run at 48 kilometers per hour for short periods. We were asked in the question, How many meters per second does the deer run?

The question gave us this (Hint: remember that there are 1,000 meters in a kilometer, 60 seconds in a minute, and 60 minutes in an hour.)

1 km = 1000 meters

48 km = x meters

Cross Multiply

= 1km × x meters = 48km × 1000 meters

x meters = 48km × 1000 meters/1 km

= 48000 meters/ hour

The speed of the dear = 48000 meters/ hour

We have to convert this to meters/ seconds

60seconds = 1 minute

60 minutes = 1 hour

Therefore, the number of seconds in one hour = 60 × 60

= 3600 seconds

Hence 48000meters/hour to meter per Seconds

= 48000meters/3600 seconds

= 13.333333333 meters/seconds

= 13.33m/s

Part B

From Part B Question, we know that Usain Bolt set a world record of 9.58 seconds for the 100 meter dash.

White-tailed deer can run at 48 kilometers per hour for short periods.

If Mr. Bolt and a white-tailed deer run a 100 meter dash at these speeds, who would win, and by how much?

Using our answer in Part A,

We know that the deer runs

48,000 meters in 3600 seconds.

The first step would be to find how many seconds it can run in an 100 meter race

Hence,

48,000 meters = 3600 seconds

100 meters = y seconds

We cross Multiply

48,000 meters × y seconds = 3600 seconds × 100 meters

y seconds = 3600 seconds × 100 meters/ 48,000 meters

y second = 7.5 seconds

This means, the deer can run a 100 meter dash in 7.5 seconds.

From the question, we know that Usain Bolt set the record of 9.58 seconds for an 100 letter dash.

The difference between both times for the Usain Bolt and the Deer = 9.58seconds - 7.5 seconds

= 2.08 seconds

Therefore the winner is the Deer , because it finishes the race is a shorter time of 7.5 seconds and wins by 2.08 seconds. Therefore, Option A) Deer wins by 2.08 seconds is correct

Answer: the answer is 20

Step-by-step explanation:

I had the same question and did my math and got it right

7. The son's age is 6 and his father's is 36.

Let the age of the son be [tex]x[/tex] and the age of his father be [tex]y[/tex],

[tex]x+y=42\\6x=y[/tex]

substitute [tex]6x[/tex] for [tex]y[/tex] in [tex]x+y=42[/tex] to find the age of the son:

[tex]x+y=42\\x+6x=42\\7x=42\\x=6[/tex]

since [tex]6x=y[/tex], substitute the value of [tex]x =6[/tex] to find the age of the father:

[tex]6x=y\\x=6\\y=6*6\\y=36[/tex]

8. The total number of fruit sold is 304.

Let oranges be [tex]x[/tex] and apples be [tex]y[/tex],

[tex]4x+5y=1479\\y=6x[/tex]

substitute [tex]6x[/tex] to find the number of oranges:

[tex]4x+5y=1479\\4x+5(6x)=1479\\4x+30x=1479\\34x=1479\\x=43.5[/tex]

now solve for [tex]y[/tex] to find the number of apples:

[tex]y=6x\\y=6*43.5\\y=261[/tex]

add the two together to find the total number of fruit:

[tex]x+y = 43.5+261=304.5[/tex] ≈ [tex]304[/tex] (rounded up because fruit count is a whole number)

Answer:

15.11 lb

Step-by-step explanation:

At a butcher​ shop, Hilda bought 4 17/20 lb of Beef and some pork. She left with 19 24/25 lb of meat. Express the number of pounds of pork she bought using a decimal

so Hilda bought ? lb of pork

Beef = 4 17/20 lb

Pork = x lb

Total Meat = 19 24/25 lb

Using decimal to express the pound of pork she bought, convert the pounds of beef and total meat she bought into decimal

Beef = 4 17/20 lb = 4.85 lb

Total Meat = 19 24/25 lb = 19.96 lb

Total meat = Beef + pork

19.96 lb = 4.85 lb + x lb

Subtract 4.85 from both sides

19.96 - 4.85 = 4.85 + x - 4.85

15.11 = x

x= 15.11 lb

Therefore, pounds of pork she bought = 15.11 lb

Answer:

She needs to eat 5 ounces of cheese and 1 ounce of yogurt

Step-by-step explanation:

Rachel should have 15 ounces of  yogurt and 14 ounces of cheese.

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here: An ounce of cottage cheese contains 3 grams of protein and 12 milligrams of calcium. An ounce of yogurt contains 1 gram of protein and 44 milligrams of calcium. let Rachel have x ounces of cheese and y ounces of yogurt. Then we have the following equations

3x+y=57

0.012x+0.044y=0.84

Solving these two equations we get y=15.3 or 15 ounces (approx)

and x= 13.9 or 14 ounces(approx) respectively.

Hence, Rachel should have 15 ounces of  yogurt and 14 ounces of cheese.
