You burn 265 calories running and then 7 calories per minute swimming.  

Your friend burns 273 calories running and then 11 calories per minute swimming.  

Let us assume that both of you swim for x minutes.  

Calories burnt by you = 265+7x  

Calories burnt by your friend = 273+11x  

Difference between both = 273+11x-(265+7x)  

= 273+11x-265-7x  

= 8+4x

A = 310 rounded to the nearest 10
GREYUIT [131]

Answer:

a = (rounded) 310

b = (rounded) 66.1

These two were already rounded to their designated rounding value.

You round up since the 3rd DP is greater than or equal to 5.

The diagram shows MNP. Which term describes point Q?
Olenka [21]

The best point that describes point Q of triangle MNP is; D: Circumcenter

<h3>What is the central point of the triangle?</h3>

We have been given an image of a triangle MNP and we are asked to choose the term that describes point Q

We see that point Q is the point where the perpendicular bisector of the given triangle is intersecting.

Due to the fact that by definition, the point where the perpendicular bisectors of a triangle intersect is called circumcenter, therefore we can conclude that, point Q is the circumcenter of triangle MNP.

How do you add 323+412 in base 5
Alenkasestr [34]

Answer:

Addition of 323+412 = 1240 at base 5

Step-by-step explanation:

We have to add 323+412 on base 5

As we have to use base 5 for addition so we can use only numbers 0,1,2,3.4 and 5 as we use 0,1,2,3,4,5,6,7,8,9,10 in decimal when base is 10

Means in addition of sum is greater than 5 then we have to take carry as in base 10 we take carry if the sum is greater than 10

So sum 323+412 = 1240

The figure below is a diagram of a trapezoidal table that needs to be stained. Each can of stain will cover 50 square inches.
alekssr [168]

The perimeter is the sum of the outside dimensions.

b1 = 87 - 32 - 14 - 13 = 28 in.

Area = (32 + 28) /2 x 12 = 60/2 x 12 = 30 x 12 = 360 square inches.

Divide area by the amount 1 can covers:

360 / 50 = 7.2 cans, round up to 8 cans are needed.
