Answer:

Mr. Johnson completed his travel in 15 minutes. But Mrs. Johnson leaves 10 minutes after he does. And to add her 12 minutes travel time, that means Mrs. Johnson will arrive in 22minutes.

Step-by-step explanation:

First, we need to find the distance (d) that Mr. Johnson traveled to be able to compute Mrs. Johnson's travel time.

To be able to do that, use the formula d = (s)(t).

d = (80miles/hr)(15mins)

d = (80miles/hr)(0.25hr)

d = 20 miles

Now that we know the distance from Cambridge to Newton, we can use this value to calculate the time Mrs. Johnson needs to complete her travel.

Using the formula t = (d)/(s);

t = (20miles)/(100miles/hr); we get:

t = 0.2hr or 12minutes

Answer:

[tex]V = \pi (2.5)^2h[/tex]

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

[tex]V = \pi (2.5)^2h[/tex]

6 is in the middle of the string of numbers,(I have no idea what spread means) and by using process of elimination, you get a, the only answer choice with 6 in the middle.

Answer:

N = 48 N = 6 x 8

Step-by-step explanation:

12 - 4 is 8. 6 x 8 is 48 so N is 48. N is 6 x 8 because 6 x 8 is 48.

Answer:

N=6×8

N=48

Step-by-step explanation:

Answer:

8( 3 + 7)

Step-by-step explanation:

I prommise this one is correct

8 is the GCF of 24 and 56

if you mutiply 3 by 8 it would equal 24

and if you mutiply 7 by 8 it would equal 56

which would leave you with 24+ 56

Answer:

8(3+7)

Step-by-step explanation:

First we list the factors of 24:

1,2,3,4,6,8,12,24

Now we list the factors of 56:

1,2,4,7,8,14,28,56

As we can see 8 is the highest number in both lists so this would mean a = 8

To factor 24+56 to 8(b+c) :

We do 24÷8 = 3 = b

and 56÷8 = 7 = c

So our final answer is 8(3+7)

Answer:

[B] A = 2 · 2

Step-by-step explanation:

Given that:

Timothy has a set of plastic squares. the tables shows the relationship between A,the area of each square in square centimeters, and s, the side length of each square in centimeters.

To Find:

Which equation can be used to represent the relationship between A and s for these squares?

Solution:

From the given table:

A = 1        S = 1             A ÷ S = 1 ÷ 1 = 1 = S

A = 4         S = 2           A ÷ S = 4÷ 2 = S

A = 49        S = 7        A÷S = 49 ÷7 = 7 = S

A = 64         S = 8        A÷S = 64÷8 = 8 = S

From the solving above we can see that the equation that can be used to represent the relationship between A and s for these square is A = S · S

you have 4 fields where it can land, so the probability has a denominator 4.

2 of those fields have a even number so the numerator is 2.

12 gallets y 6 chocolates= 42

Answer:

58 degrees

Step-by-step explanation:

It shows a square which means it is a right angle / 90 degrees. So that means because 32 degrees is already there the equation is 90 - 32 = 58 degrees.

Answer:

58 degrees

Step-by-step explanation:

A right angle is always equal to 90 degrees. So, Angle XOY (32 degrees) plus angle YOZ (x degrees) has to equal 90.

32 + x = 90

32 + x (- 32) = 90 (- 32)

x = 58

Therefore, x equals 58 degrees. I hope this was helpful! Have a lovely day!!! :D

Step-by-step explanation: I just used the formula for volume of a shpere using the radius (half of the diameter)

Answer: 376.8 cm^2

Step-by-step explanation:

The formula for the surface area of a cylinder is A = 2prh +2pr^2

When:

When we substitute our values, we get the equation

A = 2(3.14)(4)(11) + 2(3.14)(4^2)

Now, we just multiply, square, and add our numbers to find A

A = 2(3.14)(4)(11) + 2(3.14)(4^2)

A = 2(3.14)(44) + 2(3.14)(16)

A = (6.28)(44) + (6.28)(16)

A = 276.32 + 100.48

A = 376.80

Because the hundredths place is a 0, we don't need to round.

A = 376.8

The unit is in centimeters. Area, and surface area by extent, are written in cm^2 (centimeters squared)

A = 376. 8 cm^2

Answer:

The answer is B.

You only surveyed 15 people out of what could be 300. The samples is too little because the more you survey the more accurate it will be.

Answer:

c=42

Step-by-step explanation:

First you would find out how much you would add to 45 to give you 66. Which is 21. Then you double it, so when you put it over the two it looks like this 42/2. So when you reduce the fraction you get 21. Hence 21+45=66.

Hope this helps!

Answer:

C = 42

Step-by-step explanation:

½ c + 45 = 66

½ c + 45 − 45 = 66 − 45

2 × (½ c) = 2 × 21

C = 42

Answer:

A square

Step-by-step explanation:

The green square will always be a rhombus

Step-by-step explanation:

2) [tex]8\leq \frac{w}{8}[/tex]

Multiply 8 on both sides to isolate w

[tex]8\leq \frac{w}{8}\\(8)8\leq \frac{w}{8}(8)\\64\leq w[/tex]

3) [tex]18 < f-2[/tex]

Add 2 on both sides to isolate f

[tex]18 < f-2\\18 +2 < f-2+2\\20 < f[/tex]

4) [tex]\frac{y}{12} < 4[/tex]

Multiply 12 on both sides to isolate y

[tex]\frac{y}{12} < 4\\\frac{y}{12}(12) < 4(12)\\y < 48[/tex]

5) [tex]6 < r+6[/tex]

Subtract 6 from both sides to isolate r

[tex]6 < r+6\\6-6 < r+6-6\\0 < r[/tex]

6) [tex]10 > 7+x[/tex]

Subtract 7 from both sides to isolate x

[tex]10 > 7+x\\10-7 > 7-7+x\\3 > x[/tex]

7) [tex]n+1\leq 6[/tex]

Subtract 1 from both sides to isolate n

[tex]n+1\leq 6\\n+1-1\leq 6-1\\n\leq 5[/tex]

8) [tex]9x\leq 18[/tex]

Divide both sides by 9 to isolate x

[tex]9x\leq 18\\\frac{9x}{9} \leq \frac{18}{9} \\x\leq 2[/tex]

9) [tex]p+3 > 9[/tex]

Subtract both sides by 3 to isolate p

[tex]p+3 > 9\\p+3-3 > 9-3\\p > 6[/tex]

10) [tex]4\leq \frac{c}{3}[/tex]

Multiply both sides by 3 to isolate c

[tex]4\leq \frac{c}{3}\\(3)4\leq \frac{c}{3}(3)\\12\leq c[/tex]

11) [tex]k-13\leq 7[/tex]

Add 13 to both sides to isolate k

[tex]k-13\leq 7\\k-13+13\leq 7+13\\k\leq 20[/tex]

12) [tex]15 > 5x[/tex]

Divide both sides by 5 to isolate x

[tex]15 > 5x\\\frac{15}{5} > \frac{5x}{5} \\3 > x[/tex]
