Answer:

d = 28

r = 14

r² = 196

C = 87.92

Step-by-step explanation:

Given:

r = 14

To find diameter:

d = 2r

d = 2(14)

d = 28

To find r²:

14²

196

Circumference:

C = 2πr

C = 2(3.14)(14)

C = 87.92

Answer:

The 9-foot ladder would have a height of 8.55 ft against the house

Step-by-step explanation:

The angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is 71.8 degrees.

The situation forms a right angle triangle.

A right angle triangle has one of its angles as 90 degrees. The sides and angle can be found using trigonpometric ratios.

Therefore, the 9 foot and the 4 foot ladder forms the same angle.

The 4 foot ladder forms a 3.8 ft height against the wall.

Hence,

sin ∅ = opposite/ hypotenuse

sin ∅ = 3.8 / 4

∅= sin⁻¹ 0.95

∅ = 71.8051276612

∅ = 71.8°

Therefore, the angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is 71.8 degrees.

Complete question is;

A rocket ship is travelling at an average speed of 1.75 × 10⁴ miles per hour. How many miles will the rocket ship travel in 1.2 × 10² hours?

1. Write the expression:       (1.75 × 10⁴)(1.2 × 10²)

2. Rearrange the expression:     (1.75 × 1.2)(10⁴ × 10²)

3. Multiply the coefficients:      (2.1)(10⁴ × 10²)

4. Apply the product of powers:    2.1 × 10^(y)

The rocket ship will travel 2.1 × 10^(y) miles. What is the value of y in the solution?

Answer:

Distance travelled by rocket ship = 2.1 × 10^(6) miles

y = 6

Step-by-step explanation:

1. The written expression;

(1.75 × 10⁴)(1.2 × 10²)

2. The rearranged expression is;

(1.75 × 1.2)(10⁴ × 10²)

3. Let's multiply the coefficient which is the first bracket to get;

2.1(10⁴ × 10²)

4. Applying the product of powers means we will add the powers of ten which are 4 and 2.

Thus; 2.1(10^(4 + 2)) = 2.1 × 10^(6) miles

Comparing to 2.1 × 10^(y), we have;

y = 6

Given:

The figure of a trapezium.

To find:

The measures of missing angle [tex]m\angle K, m\angle M[/tex].

Solution:

In the given figure [tex]JK\parallel ML[/tex].

If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.

[tex]m\angle J+m\angle M=180^\circ[/tex]         (Supplementary angles)

[tex]87^\circ+m\angle M=180^\circ[/tex]

[tex]m\angle M=180^\circ-87^\circ[/tex]

[tex]m\angle M=93^\circ[/tex]

Similarly,

[tex]m\angle L+m\angle K=180^\circ[/tex]         (Supplementary angles)

[tex]51^\circ+m\angle K=180^\circ[/tex]

[tex]m\angle K=180^\circ-51^\circ[/tex]

[tex]m\angle K=129^\circ[/tex]

Therefore, [tex]m\angle M=93^\circ[/tex] and [tex]m\angle K=129^\circ[/tex].

Answer: Yes

You still need to simplify 3/12 because it is not in its MOST simplified form.

3/12 can be simplified to 1/4 by dividing 3.

Answer:

55

Step-by-step explanation:

180−43−82=55(angles of a triangle add upto 180)

What would the measure of the third angle equal?

Well given that all 3 vertices of a triangle are supposed  to be a sum of 180*

Hence this information side E is 82* and side H is 43* and when added up they equal 125 so then you would subtract 180 - 125 =  55\

Therefore, side T = 55*

y = -1/4x + 2

Step-by-step explanation:

Pick two points on the graph. Points (-4, 3) and (4, 1).

[tex]\frac{x_{2} - x_{1} }{y_{2} - y_{1} }[/tex]

[tex]\frac{3-1}{-4-4}[/tex]

= [tex]-\frac{1}{4}[/tex]

Slope is [tex]-\frac{1}{4}[/tex].

The y-intercept is the point where the line intersects the y-axis. In this case, it's (0, 2). So +2.

y = -1/4x + 2

Answer:

s = ≥34

Step-by-step explanation:

The speed of the  truck, s, must be no less than 34 miles per hour

is s ≥ 34.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, The speed of a truck, s, must be no less than 34 miles per hour.

Therefore, The speed of the truck must be greater than or equal to 34 miles per hour.

So, The inequality that represents this context is,

s ≥ 34.

y= -x

y= 3/2 -5

Step-by-step explanation:

The sum of two numbers is zero.

x + y = 0

y = -x

Twice the smaller number subtracted from 3 times the larger number is 10.

Let x represent the larger number and y represent the smaller number.

Twice the smaller number: 2y

3 times the larger number: 3x

Twice the smaller number subtracted from 3 times the larger number is 10.

3x - 2y = 10

-2y = -3x + 10

y = 3/2 x - 5

The equations are:

y = -x

y = 3/2 x - 5

Step-by-step explanation:

x = 180 - 100

x = 80

Answer:

Step-by-step explanation:

According to law of indices

log a b = 1/ log b a

hence log c (2) = 1/log 2 (c)

log 2 (c)⋅log c (2)

=  log 2 (c)⋅ 1/log 2 (c)

= log 2 (c)/log 2 (c)

= 1

Hence the required answer is 1

Answer:

Yes, the shapes are similar. Note, the angles are equivalent and the sides are scales of each other satisfying the requirements for similarly.

Step-by-step explanation:

For a shape to be similar there are two conditions that must be met. (1) Must have equivalent angles (2) Sides must be related by a scalar.

In the two triangles presented, the first condition is met since each triangle has three angles, 90-53-37.

To test if the sides are scalar, each side must be related to a corresponding side of the other triangle with the same scalar.

9/6 = 3/2

12/8 = 3/2

15/10 = 3/2

Alternatively:

6/9 = 2/3

8/12 = 2/3

10/15 = 2/3

Since the relationship of the sides is the scalar 3/2 (Alternatively 2/3), then we can say the triangles meet the second condition.

Given that both conditions are satisfied, then we can say these triangles are similar.

Note, this is a "special case" right triangle commonly referred to as a 3-4-5 right triangle.

Cheers.

Answer: The height of street sign = 15

Step-by-step explanation:

At the same time, the angle made by the light on each object is the same.

Pole and street sign both standing vertical to the ground.

So triangle made by both of them are similar

The sides of similar triangles are proportional,

[tex]\dfrac{\text{height of street sign}}{\text{height of pole}}=\dfrac{\text{Length of the shadow made by street sign}}{\text{Length of the shadow made by pole}}\\\\\dfrac{\text{height of street sign}}{40}=\dfrac{12}{32}\\\\\text{height of street sign}=\dfrac{12}{32}\times40=15[/tex]

Hence, the height of street sign = 15
