Answers

Answer:

Slope = 2/7

y-intercept = 0

Proportional = yes

It is proportional since we require no additional terms to get y from x and we can multiply each x term by a certain factor to get the y values

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

From what we can see, the slope of the given line is 2/7

As we can see, there is no y-intercept; so the y-intercept value is 0

As we can see, we can multiply each x value by 2/7 to get the corresponding y-value

What this mean is that both variables are proportional

The sum of three consecutive integers is 9. What is the equation that represents the scenario?
a.n + (n + 1) + (n + 2) = 9

c.n + (n – 1) + (n – 2) = 9

Answers

Answer:

8) 10 15/16 ft³

9) 20 5/6 ft³

Step-by-step explanation:

Volume of a rectangular prism is

l * b * h,

Question 8

We're given the area

Area = l * b

So we substitute the area for length and breadth.

Volume = Area * height

Volume = 4 3/8 * 2 1/2

Volume = 35/8 * 5/2

Volume = 175/16

Volume = 10 15/16 ft³

Question 9

Volume = 5 * 1 2/3 * 2 1/2

Volume = 5 * 5/3 * 5/2

Volume = 5 * 25/6

Volume = 125/6

Volume = 20 5/6 ft³

Fill in the blanks. Then, choose the property of addition you used.

Answer:

Problem 1:

Width of the larger version = 2.99 in.

Problem 2:

Friday = 5⅞ miles

Step-by-step explanation:

Problem 1:

Since the cell-phones are similar in shape and the width and length of both are proportional, therefore:

Width of the bigger phone/Width of the smaller phone = length of the bigger phone/length of the smaller phone

Width of smaller phone = 2.6 in.

Length of smaller phone = 5.4 in.

Width of bigger phone = x = ? in.

Length of bigger phone = 6.21 in.

Therefore:

6.21/5.4 = x/2.6

Cross multiply

5.4 × x = 2.6 × 6.21

5.4x = 16.146

Divide both sides by 5.4

x = 16.146/5.4

x = 2.99

Width of the larger version = 2.99 in.

Problem 2:

Jen's goal for the 5 days = 22 miles

The number of miles she ran Mon to Thursday was given.

To meet her goal, let's find the number of miles she has to run to meet her goal.

Thus:

Number of miles to run on Friday = 22 - (4¾ + 5⅛ + 0 + 6¼)

Change to improper fraction

= 22 - (19/4 + 41/8 + 0 + 25/4)

= 22 - ((38 + 41 + 0 + 50)/8)

= 22 - 129/8

= (176 - 129)/8

= 47/8

= 5⅞ miles

Answers

Answer:

large = 12

medium = 18

Step-by-step explanation:

L + M = 30 => L = 30-M

4L+3M =102

substitute : L with M

=> 4(30-M)+3M =102

120-4M+3M = 102

- M = 102-120

-M = -18

=========> M = 18, L = 12

[tex]=\dfrac{1}{d}\left[\dfrac{a_{40}-a_1}{a_1a_{40}}\right][/tex]

Between 06 00 and 10 00,the same day ,the volume of water in a reservoir decreased from 24 000L to 18 000L.What was the average rate of decrease in volume of water, giving your answer in L/h?

Answers

Answer:

-1.5 L/h

Step-by-step explanation:

The volume of water in a reservoir decreased from 24.000L to 18.000L between 06.00 and 10.00.

We need to find the average rate of decrease in volume of water. It can be solved as follows :

[tex]Rate=\dfrac{18-24}{10-6}\\\\=-1.5\ L/h[/tex]

The negative sign shows the decrease in volume. Hence, the rate of decrease in volume of water is 1.5 L/h.

80.5π cm

Step-by-step explanation:

We want to find the area where the label should go onto the can. If we were to take the label and flatten it onto a 2D surface, we would multiply 11.5 cm by the width, which is equivalent to the circumference of the circle. The circumference of the circle can be calculated using the equation 2πr. The radius is 3.5 cm, so the circumference of the circle is 7π. We multiply 7π by 11.5 to get 80.5π cm.

what is the value of x? i need the work for it as well thank you so much!

Answers

the answer would be x=19

Answer:

x=19

Step-by-step explanation:

okay so all those angles there are pretty simple. because of the vertical angles theorem, the angles that go across from each other are equal to each other. On a thing like this those intersections are congruent. So knowing this we can assume that (6x+4)=118. so if you solve the basic algebra for that (you can use mathpapa or smt if you really need the work for that) then it comes out as x=19 which you can check.

6x+4=118

subtract 4 from both sides

6x=114

divide by 6 on both sides

x=19

Answers

Answer:

Step-by-step explanation:

Answer:

19° = m∠B

73° = m∠T

88° = m∠R

Step-by-step explanation:

Let x = measure of angle B

then 4x - 3 = measure of angle T

 and 31 + 3x = measure of angle R

x + 4x - 3 + 31 + 3x = 180

8x + 28 = 180

8x = 152

x = 19° = m∠B

4(19) - 3 = 73° = m∠T

31 + 3(19) = 88° = m∠R
