Help me please thanks

Answer:

A)  5/13

Step-by-step explanation:

Total number of cars counted:

= red cars + not red cars

= 25 + 40

= 65

Therefore, the probability that the next car is red = number of red cars counted ÷ total number of cars counted

[tex]=\dfrac{25}{65}[/tex]

Divide the numerator and denominator by 5 to simplify:
[tex]=\dfrac{25 \div 5}{65 \div 5}=\dfrac{5}{13}[/tex]

Answer:

The longest insect is 5/8 inches longer than the shortest.

To find how much longer the longest insect is than the shortest, we have to subtract the length of the shortest insect from the longest one.

The shortest insect is 1/8 inches

The longest insect is 3/4 inches

So, we have to do 3/4 - 1/8

To do that, we have to find a common denominator

A denominator is the bottom number of a fraction

A common denominator between 3/4 and 1/8 is 8

We can write 3/4 as 6/8 because they are equal

Now we do 6/8 - 1/8

6/8 - 1/8 = 5/8

5/8

Answer:

She would save $2

Step-by-step explanation:

     We can solve how much 144 sodas will cost in each place, and then compare the difference between them.

     [Solving]

     144 sodas are needed in total.

     Price Co is 36 diet sodas for 10 dollars.

-> 144 / 36 = 4

-> 4 * $10 = $40 at Price Co

     Save More is 24 diet sodas for 7 dollars.

-> 144 / 24 = 6

-> 6 * $7 = $42 at Save More

     [Compare differences]

$42 - $40 = $2

-> She would save $2 by purchasing the drinks at Price Co.

Answer:

x = 47

Step-by-step explanation:

1. Understanding

a. Know that a straight line is 180 degrees total

2. Subtract

a. Knowing that a straight line is 180 degrees in total, you have to subtract

b. Subtract 180 - 86, where 180 is the angle of the straight line and 86 is the given variable.

180-86= 94

3. Divide

a. It says to find 2x, and you have to do opposite operations to find x

b. You have to divide 97/2 to get 2x, because when you get the number, then you have to find 2x of that number, and then you have to multiply.

c. 97/2 = 47 Degrees

4. Check

a. 2x = 2(47)

b. (47)2 = 47 x 2 = 94

c. 94 + 86 (Given variable) = 180

And a straight line is 180 degrees meaning that this is correct

x = 47

Hope this helps :)

Answer:

[tex]y=\cfrac{1}{2}\;x-4[/tex]

x   |  y

10    1    = 1/2 (10) -4=5-5= 1

-2    -5  = 1/2(-2)-4=-1-4= -5

4     -2   = 1/2(4)-4=2-4= -2

-8    -8  = 1/2(-8)-4=-4-4= -8

Answer:

x   |  y

10    1   = 1/2 (10) -4= 1

-2    -5  = 1/2(-2)-4= -5

4     -2   = 1/2(4)-4= -2

-8    -8  = 1/2(-8)-4=- -8

Just put the values of x into the equation and calculate the value of y

Answer:

118 because in this rhombus it is a square tilted on its side, so, that makes the opposite angles congruent, which means y=118.

Answer:

To find the volume of a cone, use the equation: V = 1/3Bh.

In this equation, V is the volume, B is the base, and h is the height.

We are given that the base is 12 inches, and the height is 18 inches. With those necessary values, we can substitute those values, and calculate it.

V = 1/3(12)(18)

V = 4(18)

V = 72.0

Therefore, the volume of this glass is 72.0 cubic inches.

Answer:

42.9%

Step-by-step explanation:

The person above gave the correct answer, I got it right

250,000 -175,000 = 75,000

75,000 divided by 175,000 = 0.42857142857

0.42857142857 x 100 = 42.9

42.9% is the percent change

Answer:

the answer is 6107.24 meters cubed filled.

Step-by-step explanation:

the volume of a hemisphere is v=(2/3)πr^3

simply plug in the radius which is 9 since its half the diameter to get

v=(2/3)π9^3

v=(2/3)π729

v=(2/3)2290.22

v= 1526.81

the volume of 1 bowl is 1526.81

after this you just have to multiply it by 4 to get the total volume needed

1526.81*4=6107.24

Answer:

Elena won the race.

Step-by-step explanation:

If you calculate it, Lin runs a mile every 9 minutes.

9 times 7.5= 67.5 which is 1 hour, 7 minutes and 30 seconds. While it took only an hour for Elena to run 7.5 miles.

Which means Elena's speed was faster and got her to the finish line first.

Answer:

y=-1/3x+17/3

Step-by-step explanation:

1. find the slope:

y2-y1/x2-x1

=1/-3

∴=-1/3

2. find b

y=-1/3x+b

substitute y and x

5=-1/3(2)+b

5=-2/3+b

17/3=b

∴b=[tex]\frac{17}{3}[/tex]

3. final equation

y=[tex]-\frac{1}{3}[/tex][tex]x[/tex]+[tex]\frac{17}{3}[/tex]

Answer:

Its correct keep up the good work :>

Step-by-step explanation:

Answer:

Step-by-step explanation:

Select the correct answer from each drop-down menu. A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 33, where x represents the smaller number. Plugin the numbers from the set {3, 5, 7, 9} to find the value of x. The value of x that holds true for the equation is 7. So, the smaller number is 7 and the larger number is 26 .

Find the value of x in x + 3x + 5 = 33, using {3, 5, 7, 9}

3:

x + 3x + 5 = 33

3 + 3(3) + 5 = 33

3 + 9 + 5 = 33

12 + 5 = 33

17 = 33

This is false, 17 does not equal to 33. <== wrong

5:

x + 3x + 5 = 33

5 + 3(5) + 5 = 33

5 + 15 + 5 = 33

20 + 5 = 33

25 = 33

This is false, 25 does not equal to 33. <== wrong

7:

x + 3x + 5 = 33

7 + 3(7) + 5 = 33

7 + 21 + 5 = 33

7 + 26= 33 <== (smaller number = 7, larger number = 26)

33 = 33

This is true, 33 does equal to 33. <== correct

9:

x + 3x + 5 = 33

9 + 3(9) + 5 = 33

9 + 27 + 5 = 33

36 + 5 = 33

41 = 33

This is false, 41 does not equal to 33. <== wrong

Not that we know that x = 7 (the smaller number), we need to find 3x (the larger number)

3x

3(7) = 21

Now, we add that to our original 5

21 + 5 = 26

Therefore, the smaller number is 7, while the larger number is 26.

Hope this helps!

Answer:

The first sack had 80lb.

The second sack had 60lb.

Step-by-step explanation:

1) So we know that at the end, both sacks had to be even & when added, equal to 140. That would mean both sacks would be 70lb after taking 1/8 from the first sack.

2) If we add 10lb. to the first sack we make it 80lb. That means we would have to take away 10lb from the second sack, making it 60lb. We know we can do this b/c the sum of 80+60=140

3) 1/8 of 80 is 10. So take 10lb away from the 1st sack and give it to the 2nd sack, and both sacks are even at 70lb and their sum is 140lb.

4) That means that originally the 1st sack weighed 80lb and the 2nd sack weighed 60lb.

Answer:

First snack contains 80 lb.

The second snack contains 60 lbs

Step-by-step explanation:

We know  in the end , both bags must be even and equivalent to 140 once totaled. This means the sacks would indeed be 70lb following subtracting 1/8 the first.

We can make the first bag 80 lb by adding 10 lb to it. That means we'd have to subtract 10 lb from the next sack, bringing it to 60 lb. We assume we can achieve it since  140 is the what you get when you do 80+60.

10 is the answer of 1/8 of 10. So remove 10lb from the first sack and put it in the second, and both bags are even at 70lb, and their total is 140lb.

This suggests that the very first sack is 80 lbs and the second one is 60 lbs.

Answer:

Step-by-step explanation:

The volume of the prism is 3 cube units, which means that the prism can be filled with 3 [tex]1*1*1[/tex].

Here, there are 64 cubes with 1/4 units side lengths in 1 cubic unit.

Since the rectangular prism is made up of 3 cubic units, we would have

3 * 64  total cubes with 1/4 units side lengths.

[tex]3*64=192[/tex]

Therefore, it takes 192 of the 1/4 unit cubes to fill the prism.
