Simplify the following expression.

Step-by-step explanation:

a) d = 60 mi

t = 45 min = 0.75 hr

v = d/t

= (60 mi)/(0.75 hr)

= 80 mi/hr

b) t = d/v

= (75 mi)/(50 mi/hr)

= 1.5 hrs

Answer:

C, 5:9

Step-by-step explanation:

Answer:

5/9

Step-by-step explanation:

Context for variables

sw: number of sweaters

j: number of jeans  

sk: number of skirts

The following three equations are established from the question:

sw + j + sk = 120

sw/j = 8/3

j/sk = 3/4 or sk/j = 4/3

Dividing the first equation by j, we get:

sw/j + j/j + sk/j = 120/j

8/3 + 1 + 4/3 = 120/j

5 = 120/j

j = 120/5 = 24

sw = 24*8/3 = 64

sk = 24*4/3 = 32

After the replacement the new number of jeans and skirts are:

j' = 24 - 4 = 20

sk' =  32 + 4 = 36

the new ratio of jeans to skirts is:

j'/sk' = 20/36 = 5/9

Answer:

3/7 is the probability that the teacher will randomly select a boy.

Hope this helps! :)

The probability that the teacher randomly selects a boy is 3/7

The given parameters are:

Boy = 6

Girls = 8

The total number of students is:

Total = 6 + 8 = 14

The probability of selecting a boy is:

P(Boy) = 6/14

Simplify

P(Boy) = 3/7

Hence, the probability that the teacher randomly selects a boy is 3/7

Answer:

if pi is 3.14: 163.52 [tex]m^2[/tex]

if pi is just π: 264 - 32π [tex]m^2[/tex]

Step-by-step explanation:

22 x 12 = 264

4 x 4 = 16

16 x 2 = 32

16 x 3.14 = 50.24

264 - 50.24 x 2 = 163.52

Answer:

163.47

Step-by-step explanation:

We know the area of the whole rectangle by multiplying 12 by 22 to get 264. Now we just have to find the area of the circles and subtract it from the rectangle.

The area of a circle is πr^2. These circles' radii is 4, so 4^2π = 16π

Since there are 2 circles, double 16π to get 32π, 32π is equal to 100.53096491, rounded to 100.531. 264 - 100.531 = 163.469, rounded to 163.47

1/3 of 80= 26.7(1dp)

1/4 of 80= 20

26.7+20= 46.7(1dp)

80-46.7= 33.3(1dp)

Either 33 or 34 people

Answer:

30

Step-by-step explanation:

We can estimate that 1/4 people had cereal and after that, half chose eggs/ meat over toast/roll.

1/4 * 80 is 20 So we are left with 60.

60/2  is 30.

So I would estimate 30 people chose eggs and meat.

Step-by-step explanation:

Answer:

1)0.6x=54  2)90

Step-by-step explanation:

1) 60% is the same as 0.6 and finding 60% is the same as as doing 0.6 times whatever the number is and here we don't know the number so it would be x. so 0.6 times x or 0.6x=54. You could also just write 60% of x=54

2) You would have to do the opposite of finding 60%.

So you would do 54/6=9 and 9*10=90. this is because to find 60% you have to do divide by 10 and times by 6. So you do the opposite. you can check your answer by doing 60% of 90. So 90/10= 9 and 9*6=54. Therefore his fundraising goal is $90

y=1/2x+2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(3-(-2))/(2-(-8))

m=(3+2)/(2+8)

m=5/10

m=1/2

y-y1=m(x-x1)

y-(-2)=1/2(x-(-8))

y+2=1/2(x+8)

y=1/2x+8/2-2

y=1/2x+4-2

Answer:

5 127/200 meters

Step-by-step explanation:

4 1/2 = 4 5/10 | 4/5 = 8/10

--------------------------------------

4 5/10 = 4.5 | 8/10 = 0.8

--------------------------------------

4.8 divided by 0.8 = 5.625

--------------------------------------

5.635 = 5 635/1000

635/1000 divided by 5 = 127/200

--------------------------------------

5 + 127/200 = 5 127/200

The unit rate in meters per year is 8/45 meter/year.

Given that, a tree in John's backyard has been growing for [tex]4\frac{1}{2} = \frac{9}{2}[/tex] years. The tree is 4/5 meters tall.

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Now, unit rate = 4/5 ÷ 9/2

= 4/5 × 2/9

= 8/45 meter per year

Therefore, the unit rate in meters per year is 8/45 meter/year.
