A construction crew has just finished building a road. The crew worked for days. If they built kilometers of road each day, find the total length of road they built.

____ kilometers

Answers

Answer:

3.602 km.

Hope this helps!

Answer: If t would be the number of days, d the distance they built and x the total they built, then the relationship would be x = td.

Step-by-step explanation: If they build a certain amount of road every day, then in two days, they're gonna build twice that much road, in three days triple, etcetera. Therefore you just need to multiply the amount of days they work with the amount of road they build in a day.

Answer:

It is point c

Step-by-step explanation:

ok so the coordinates are always (x,y) so therefore if X is 0 then it stays in the middle of the graph and doesn't go anywhere. since Y is -3, y always goes down or up. so if it goes down then it is negative. up is always positive. same with x. X is always horizontal so if it moves right, it is positive and left (backwards) is negative. hope this helps and isn't confusing. *Also, since it's -3, then it goes down negative 3 units. *

Answer:

Step-by-step explanation:

In the coordinate (x,y), x refers to the place of point above the horizontal line while y represents the place of point in the side to its vertical lines.

Here, x is 0, that means it is lying on y line and y is -3, that means it's lying in 3rd quadrant. So, point C matches them completely. That's why the correct answer is C.

In a bag of marbles, the ratio of the number of blue to red to white is 13:2:6. If the number of blue marbles minus the number of white marbles is 21, how many red marbles are there?

Answers

Answer: There are 6 red marbles

Step-by-step explanation:

13 - 6 = 7

21/7 = 3

3 x 2 = 6

To check the answer:

13 x 3 = 39

6 x 3 = 18

39 - 18 = 21

Answer:

Step-by-step explanation:

Blue = 13x

Red = 2x

White = 6x

Now, they have given one more info:

Blue - White = 21

So, 13x - 6x = 21

7x = 21

x = 3

∴ Now, Blue = 13*3 = 39

Red = 2*3 = 6

White = 6*3 = 18

Total = 63

Regan and her friends shared a Big Dipper sundae at Skylight Ice Cream Shop. The 3 of them split the bill, and each person paid $3.75.
Let b represent the total cost of a Big Dipper sundae. Which equation models the problem?

Answers

Answer: B=$3.75×3

Explanation: we want the full price of the Big Dipper so the equation will equal to B, there were 3 friends that split the bill $3.75 each so if we multiple 3.75 by 3 we will get the total cost of the Big Dipper which is $11.25

The solution is: b=$3.75×3, the equation models the problem, when b represent the total cost of a Big Dipper sundae.

Here, we have,

Regan and her friends shared a Big Dipper sundae at Skylight Ice Cream Shop.

The 3 of them split the bill, and each person paid $3.75.

Explanation:

we want the full price of the Big Dipper so the equation will equal to b, there were 3 friends that split the bill $3.75 each

so if we multiple 3.75 by 3

we will get the total cost of the Big Dipper which is $11.25

i.e. 3.75 × 3

= 11.25

So, b=$3.75×3, the equation models the problem, when b represent the total cost of a Big Dipper sundae.

surface area of cuboid

Answers

Answer:

Volume equals 60

Step-by-step explanation:

volume = (width)(height)(length)

volume= (2.5)(4)(6)

volume= 60

The amount of glass used is equivalent to the surface area of the glass surfaces.

As the problem is specifying the top of the aquarium is open, we'll assume that it is not included for the surface area calculations.

[tex]A=2 (2.5 \times 4) +2(6\times4)+(6\times2.5)[/tex]

The first term represents the area of two 2.4 x 4 faces of the aquarium. The second term is the area for the two 6 x 4 faces. The last term is for the 6 x 2.5 base of the aquarium, and it is not multiplied by 2 as we are not including the top of the aquarium.

[tex]=2 \times 10 + 2\times24 + 15[/tex]

[tex]=83 \text{ ft}^2[/tex]

The aquarium has a surface area of 83 square feet. Hence, 83 square feet of glass was used to build the tank.

Let me know if you have any questions, thanks!

Elizabeth is thinking of a two-digit number. When the tens digit is subtracted from the ones digit, the difference is 2. One-fifth of the number is 1 less than the sun of the digits. What is the number?

Answers

Answer:

Step-by-step explanation:

The answer is 35 because 5-3=2. And 5+3=8. 1/5 of 35 is 7 which is one digit less than 8.

I hope this helps!

Answer:

Step-by-step explanation:

Let's start by placing 35 in the spot for x. When the tens digit (3) is subtracted from the ones digit (5), the difference is two. Let's see if it works. 5-3=2. So far, we're good! Now one-fifth of 35 is 7, which, is 1 less than the sum of both 5 and 3 which is 8. 8-1=7.

why are fifteenths show in the example model?

Answers

Answer: Fifteenths are shown in the example model because the denominator of your answer is also 15.

Step-by-step explanation:

Like what I'm trying to say is is that this is common sense and also I don't know why your math book would want you to solve this but, since the answer is 6/15 then it wouldn't make sense for your answer table to have 16 spaces instead of 15. Like common sense, although I can get why you're confused.

(b) In the equation x is the dependent variable and y is the independent variable.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here

Adrien has 4 liters of milk. He drinks y liters each day.
Adrien has x liters of milk left after one week
So
x = 4 - 7y

In the above equation model, it is clear that x changes as y changes, although x is the dependent variable and y is the independent variable.

Determine if the table shows a proportional relationship.

x 36.5 23.2 63.3
y 18.25 11.6 21.1
Group of answer choices

a. Yes, it is proportional because the ratios for y over x are all equivalent to one-half.

b. Yes, it is proportional because the ratios for y over x are all equivalent to one-third.

c. No, it is not proportional because 18.25 over 36.5 is not equal to 23.2 over 11.6.

d. No, it is not proportional because 18.25 over 36.5 is not equal to 21.1 over 63.3

Answers

Answer:

Because 18.25/36.5 and 21.1/63.3, the numbers in the table do not represent a proportionate connection. First set of data: y/x = 18.25/36.5 = 0.5

Values for the second pair are: y/x = 11.6/23.2 = 0.5

Values for the third pair are: y/x = 21.1/63.3 = 0.3

Because the value of y/x varies among the table's values, the table does not depict a proportionate connection. A value table must have an identical ratio of y/x between each pair of values for a proportional relationship to be seen. K, or the proportionality constant, is the constant.

Because 18.25 over 36.5 is not equivalent to 21.1 over 63.3, we may conclude that: D. No, does not demonstrate a proportionate connection.
