Answer 1

Part (a)

Answer: 42

-------------

Work Shown:

The angle ABC is 90 degrees since AB and BC are perpendicular. The two segments form a right angle. Therefore, the three pieces of the angle must add to 90

24+x+24 = 90

x+48 = 90

x+48-48 = 90-48 ... subtracting 48 from both sides

x = 42

=======================================

Part (b), subpart (i)

Angle q is congruent to the 135 degree angle because they are vertical angles.

Vertical angles are opposite angles formed by the X shape when two lines cross, and vertical angles are always the same measure.

=======================================

Part (b), subpart (ii)

Answer: 225

-------------

Reasoning:

The four angles p,q,r and the 135 all add to 360, so,

p+q+r+135 = 360

subtract 135 from both sides so we isolate the "p+q+r" and that leads to

p+q+r+135 = 360

p+q+r+135-135 = 360-135

p+q+r = 225

Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary. Charlene is going to reduce her net income by $125 each month and put this money towards paying down her debt. What will Charlene’s new net income be?

Answers

Answer:

A. $113.70

Step-by-step explanation:

The new net income of Charlene is $113.7 if Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary.

What is debt?

It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.

Charlene net income = 7% of her monthly salary

Charlene net income = 3410(7/100) = $238.7

After paying the $125 from the net income:

= 238.7 - 125

= $113.7

Thus, the new net income of Charlene is $113.7 if Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary.

y > 10

Answer:

y > 10

Step-by-step explanation:

Inequality:

1/2y>5​

We need to isolate the variable y.

Since it is being multiplied by 1/2, we need to multiply by the reciprocal, or opposite, on both sides. The reciprocal of 1/2 is 2. (Check by multiplying both numbers and making sure the product is 1.)

Multiply:

y > 10

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In the triangle JKH is,

∠ JHK = 24°

∠ HJK = 96°

Hence, We can formulate;

⇒ ∠ JKL = ∠ JHK + ∠ HJK

Substitute the given values we get;

⇒ ∠ JKL = 24° + 94°

⇒ ∠ JKL = 120°

Thus, The value of the measure of JKL is,

⇒ ∠ JKL = 120°

Answers

We can rewrite 27 as 9 × 3, where 9 is a perfect square, then take it through our steps. Since 3 doesn't have any perfect square factors, √(3) is as simplified as possible, so we have that the square root of 108 in radical form is 6 × √(3), or 6√(3).

A triangle has a base of 4 units and a height of 3 units. Mark draws the triangle again but
doubles the height. How does the area of the triangle change?
The area increases by 3 square units.
The area increases by 6 square units.
The area increases by 12 square units.
The area does not change.

Answers

Answer:

The area increases by 6 square units.

Step-by-step explanation:

The original  area of triangle

A = 1/2 bh

a = 1/2 (4)*3

6 square units

Now we double the height

A = 1/2 (4) *6

A = 12 square units

The difference is 12-6 = 6  square units

Answer:

Second option: The area increases by 6 square units.

Step-by-step explanation:

A1 = ½ × 4 × 3 = 6 units²

A2 = ½ × 4 × 2(3) = 12 units²

Increase: 12 - 6 = 6 units²

Emery bought three cans of beans I had a total weight of 2.4 pounds each can of beans with the same amount which model correctly illustrates the relationship check all that apply

Answers

Answer:

Figure 2 and 3 are correct

Step-by-step explanation:

This question is incomplete, the figures are attached.

Number of cans of beans bought by Emery = 3

Total weight of cans = 2.4 pounds

Therefore the weight of each can = 2.4/4 = 0.8 pounds

The can be represented by the equation:

y = 0.8x,   where x is the number of cans and y represents the total weight

From the graph of figure 1, weight of each can =  20/16 = 1.25 pounds. This is not correct

From the graph of figure 2, weight of each can =  8/10 = 0.8 pounds. This is correct

From the table of figure 3, weight of each can =  4/5 = 0.8 pounds. This is  correct

From the table of figure 4, weight of each can =  5/4 = 1.25 pounds. This is not correct

In a running competition, a bronze, silver and gold medal must be given to the top three girls and top three boys. If 15 boys and 4 girls are competing, how many different ways could the six medals possibly be given out?

Answers

Answer:

There are a total of possible 1820 results.

Step-by-step explanation:

Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:

[tex]Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455[/tex]

[tex]Girls = \frac{4!}{3!*(4 - 3)!}\\Girls = \frac{4*3!}{3!}\\Girls = 4[/tex]

Total number of possible results:

[tex]results = 4*455\\results = 1820[/tex]

Jonathan replaced the original factory tires (P220/65 R 18) on his pickup truck with (P255/60 R 17) tires. Calculate the circumference of Jonathan’s ORIGINAL tires. Explain your results

Answers

Answer:

92 inches

Step-by-step explanation:

When a tire's size = P220/65 R 18, it means that:

the rim is 18 inches wide (or 457 millimeters)the width of the tire is 8.7 inches (or 220 millimeters)the sidewall of the tire is 5.65 inches (or 144 millimeters)the 65 shows the relationship between tire width and sidewall (65%)

the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches

the circumference = 2 x π x radius   or   diameter x π = 29.3 x 3.141592 = 92 inches
