I need help with this. Mostly just 2a and 2b.

Answers

2a. A(t) = π(70 + 6t)^2 (Let t = 2 hours)

     A(2) = π(70 + 6(2))^2 = 6724π

     Now let t = 0 hours (result from part 1)

     A(t) = π(70 + 6(0))^2 = 4900π

 

     Average rate = 6724π - 4900π/2-0 = 912π

     912π area covered per hour

2b. Let t = 1/2 hours, A(t) = π(70 + 6(1/2))^2 = 5329π,

     Let t = 0 hours - result from last time was 4900π,

     Average rate =  5329π - 4900π/1/2 - 0 = 858π

     858π area covered per hour

The formula to find the area of a circle of is: A = [tex]\pi r^{2}[/tex]

However, the question wants to use 3.14 instead of pi.

We need to find the radius. The radius of the circle is half the diameter. So, the radius to 5 yards.

Now we just plug in the formula.

Joe asked the children in his class which flavours of ice-cream they like.
He recorded the results in a Venn diagram.

How many children like chocolate ice-cream?

Answers

Answer:

a. 19

b. 14

Step-by-step explanation:

From the venn diagram, we see that:

9 children like only Vanilla

7 like vanilla and chocolate

12 like only chocolate, and

2 like neither chocolate nor vanilla

Thus:

a. Number of children that liked Chocolate ice-cream = those that like chocolate only + those that like both chocolate and vanilla = 12 + 7 = 19

19 children like chocolate ice-cream.

b. Number of children who do not like Vanilla ice-cream = those that like chocolate only + those that do not like neither chocolate nor vanilla = 12 + 2 = 14

14 children do not like vanilla ice-cream.

One of the angles in an isosceles triangle is 74°.

What could the other two angles be?

Answers

Answer:

we know that isoceles has pair of angle with same measurement and sum of interior angle of triangle is 180°

Step-by-step explanation:

Let other angle be x

x+x+74°= 180°

=> 2x = 180°-74°

=>x = 106°/2

=> x= 53°

If one of the angles in an isosceles triangle is 74°. Then the other two angles will be 53°.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In an isosceles triangle, two angles and their opposite sides are equal.

One of the angles in an isosceles triangle is 74°.

Let the other angle be x.

Then the value of x will be

x + x + 74° = 180°

            2x = 180° – 74°

            2x = 106°

              x = 53°
