Answer:

10 square units

Step-by-step explanation:

Base of triangle (b) = 4 units

Height of triangle (h) = 5 units

Therefore,

Area of triangle

[tex] = \frac{1}{2} bh \\ \\ = \frac{1}{2} \times 4 \times 5 \\ \\ = 2 \times 5 \\ \\ = 10 \: {units}^{2} [/tex]

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

Answer:

[tex]78.5yd^{2}[/tex]

Step-by-step explanation:

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.

[tex]A=3.14*(5yd)^{2} \\A=3.14*25yd^{2} \\A=78.5yd^{2}[/tex]

Answer:

12

Step-by-step explanation:

Pythagoras Theorem is clearly used in this question.

To Calculate the Hypotenuse:

C = [tex]\sqrt{a^2+b^2}[/tex]

The Adjacent angle has already given as 9, so you can factor that into the question.

In Order to calculate the Opposite angle you need to use the following formula.

[tex]b = \sqrt{c^2-a^2}[/tex]

With the integers we already have for both Hypotenuse and Adjacent factored in this will be your equation:

[tex]b = \sqrt{15^2-9^2} = 12[/tex]

Therefore you answer is 12, Hope this helps, feel free to make as brainilest.

Answer:

C) 53.3%

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = 0.5328 = 53.3%

Step-by-step explanation:

Explanation

Given that Mean of the Normal distribution(μ)  = 222

Given that the standard deviation of the Normal distribution (σ) = 16

Let 'X' be the random variable in the Normal distribution

we have to find that the probability that a data value is between 206 and 230

solution:-

Step(i):-

Let  'X' = 206

[tex]Z = \frac{x^{-}-mean }{S.D} = \frac{206-222}{16} = -1[/tex]

Let X = 230

[tex]Z = \frac{x-mean }{S.D} = \frac{230-222}{16} = 0.5[/tex]

Step(ii):-

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = P( -1≤Z≤0.5)

                          = |A(0.5)+A(-1)|

                         = 0.1915+0.3413

                         = 0.5328

final answer:-

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = 0.5328 = 53.3%

Answer: centimeter

Step-by-step explanation:

The best unit of measurement for measuring the foot will be centimeter.

A unit of measurement is a standardized quantity of physical property, used as a factor to express the quantity of that property that exists. Among the first devices invented by humans were measuring units.

Given that, which will be the best unit of measurements for measuring the foot,

So, from the given options, the kilometer is very long for a human foot, millimeter is too small for a human foot and meter is also slightly longs,

We often measure the human body parts like hand, nose, tongue etc. in cm.

Hence, the best unit of measurement for measuring the foot will be centimeter.

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°.

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°

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.

Answer:

The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles. The adjacent angles are the angles which have a common vertex.
