Goryan [66]

Answer:

Step-by-step explanation:

So we have the set of numbers: 3,4,4,5,5,2,5,4,6,3,6,5,3.

Mode just means the most repeated number so let's sort them into groups.

(2) (3,3,3) (4,4,4) (5,5,5,5) (6,6).

the most repeated number is 5 which we see in the sequence about 4 times.

Two bags had 100 kilograms of sugar each. after taking out 3 times as much sugar from bag one than bag two, bag one had half as

Serjik [45]

According to the given statement, we can get the equation:

50 - 3x = 1/2 (50-x)

where x = amount removed from bag two, 3x removed from bag one

Then we multiply both sides by 2 (to eliminate the ½)

100-6x= 50-x

Add 6x to both sides

100= 50-5x

Then subtract 50 from both sides

50=5x

Lastly, divide by 5

10=x

Therefore 10 kg of sugar was removed from bag 2

further, 3x= 30, so 30 kg of sugar was removed from bag 1.

50-30=20 kg remaining in bag 1.

<span>50-10=40 kg remaining in bag 2.</span>

What is the surface area, measured in square centimeters, of the shapebelow? Do not include units in your answer.

aleksandr82 [10.1K]

SOLUTION

The figure in the question is a cuboid with

length = 7 cm, width = 3cm and height = 4cm

Surface area of a cuboid is given as

$\begin{gathered} S=2(lw+lh+wh) \\ S=2((7\times3)+(7\times4)+(3\times4))_ \\ S=2(21+28+12) \\ S=2(61) \\ S=2\times61 \\ S=122cm^2 \end{gathered}$

Hence the answer is 122 square-centimeters

The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at

tia_tia [17]

We are given:

The time t required to drive a certain distance varies inversely with the speed r.

According to the question t is inversely proportional to speed(r).

let us say distance (d) is constant of proportionality,

So the equation becomes,

$t=\frac{d}{r}$

Now from the question, we are given it takes 2 hours to drive the distance at 67 miles per hour, so plugging these in the above equation,

$2=\frac{d}{67}$

d=134 miles.

Now we have to find how long will it take to drive the same distance that is 134 miles at 55 miles per hour

so plugging the values, we have,

$t=\frac{134}{55}$

t=2.436

So the time taken will be around 2.5 hours.

Answer : It will take about 2.5 hours to drive the same distance at 55 miles per hour. Option C. About 2.5 hours.
