Geoffrey and his babysitter spent 20 minutes preparing dinner, 2 hours and 30 minutes playing board games, and half an hour making dessert. How many minutes did they spend doing these activities?

Answers

Answer 1

Answer: 200 minutes
20 + 60 + 60 + 30 + 30 = 200

Answer 2

Answer: This is very simple!!
.
Don't worry, no need to panic.
.
Just add the number of minutes up!!
.
Write the numbers that you can see are evident down.
.
20... 2 hours and 30 minutes... no more.
.
BUT WAIT!!
.
Half an hour looks suspicious.
.
Isn't that 30 minutes?
.
Add that to our list.
.
Now, we have to convert 2 hours to minutes.
.
Arggggh!!
.
Don't worry, there's 60 minutes in an hour, so 60 x 2 is 120 minutes!!
.
Add em' up!!
.
20 + 120 + 30 + 30 is...
.
200 minutes!!
.
Or, 3 hours and 20 minutes.
.
Hope I helped!!

which of the following represent the equation of a line with the slope of 1/4 that passes through the point (-8,2)

Answers

Answer:

The equation of a line with the slope of 1/4 that passes through the point (-8,2) is $y=(x)/(4)+4$

Solution:

Given, slope of a line is $(1)/(4)$ and a point is (-8, 2)

We have to find the line equation with above given values.

Now, we know that, point slope form of a line is

$y-y_(1)=m\left(x-x_(1)\right)$

Where, m is slope of line and $\left(x_(1), y_(1)\right) \text { is point on that line. }$

Here in our problem, $\mathrm{m}=(1)/(4) \text { and }\left(\mathrm{x}_(1), \mathrm{y}_(1)\right)=(-8,2)$

So, substitute above values in general form.

$\begin{array}{l}{y-2=(1)/(4)(x-(-8))} \n\n {y-2=(1)/(4)(x+8)}\end{array}$

4(y – 2) = (x + 8)

4y – 8 = x + 8

x – 4y + 8 + 8 = 0

x – 4y + 16 = 0.

4y = x +16

$y=(x)/(4)+4$

Hence the equation of a line with the slope of 1/4 that passes through the point (-8,2) is $y=(x)/(4)+4$

Answer:

y = 1/4x + 4 or y - 2 = 1/4(x + 8)

an object that weighs 10 lb on earth would weigh only 4lb on mars. If you weigh 95 lb on earth, how much would you weigh on mars

Answers

The weight of the object on mars when the weight on earth is 95 lb is 38 lb.

What are ratios?

We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. One is the part-to-whole ratio, and the other is the part-to-part ratio. The link between two distinct entities or groupings is depicted by the part-to-part ratio.

Given weight on earth = 10 lb

weight on mars = 4 lb

so weights are in ratio = 10/4

when weight on earth = 95 lb

then weight on mars be x

95/x

since both weights are of earth and mars then they are in proportion,

10/4 = 95/x

x = 95 x 4/10

x = 38 lb

Hence weight on mars is 38 lb.

#SPJ3

you need to find the unit rate.
10/4 will be 95/x so 4 divided by 10 equals 0.4
then you multiply 0.4 by 95 which equals 38
so you will weigh 38 pounds on mars since:
10/4=1/0.4 1/0.4=95/38
