Answer:
[tex]30 {in}^{2} [/tex]
Step-by-step explanation:
First we have to find the value of the other leg of the triangle. To find that we can use the PYTHAGORAS theorem because this is an right triangle.
[tex] {h}^{2} = {p}^{2} + {b}^{2} \\ {13}^{2} = {12}^{2} + {b}^{2} \\ 169 = 144 + {b}^{2} \\ 169 - 144 = {b}^{2} \\ 25 = {b}^{2} \\ b = \sqrt{25 } \\ b = 5 \: \: in[/tex]
Now let's find the area.
[tex]area = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 5 \times 12 \\ = \frac{60}{2} \\ = 30 {in}^{2} [/tex]

Which of the following statements are true?
Answer: It’s A
Step-by-step explanation:
For a given rectangle the length equal 3x + 2 and the width equal 5 what is the area of the rectangle
Answer:
15x + 10.
Step-by-step explanation:
To find the area of a rectangle, recall the formula is A = l × w. Therefore:
A = (3x + 2) (5)
Distribute the '5':
A = 15x + 10
Therefore, the area of the rectangle of 15x + 10.
Answer:
15x+10 units ^2
Step-by-step explanation:
The area of a rectangle can be found using:
A = l * w
The length of the rectangle is 3x+2 and the width is 5.
l=3x+2
w=5
Substitute these values into the formula.
A= 3x+2 *5
This can be rewritten as: (Commutative property of Multiplication)
A= 5* 3x+2
A= 5(3x+2)
Distribute the 5. Multiply each term inside the parentheses by the number outside the parentheses.
A= (5*3x) + (5*2)
A= 15x +10
A= 15x+10 units^2
The area of the rectangle is 15x+10 square units.

Plz help asap, dhhdudhdhd
Answer:
x=15°
Step-by-step explanation:
Angles ∠2 and ∠4 are supplementary, so ∠2+∠4=180°
That equals to 2x+10+4x+80=180.
You can solve that equation to find what x is equal to.
2x+10+4x+80=180

John charges a flat fixed fee of $10 PLUS a certain rate per hour for each hour for cutting the grass. John earned $100 one day, cutting the grass in a circular lawn. On the next day, to cut the grass in a similar adjacent circular lawn one third the circumference, how much money can he expect to make? ( with explanation )
Answer:
33.33 dollars
Step-by-step explanation:
Answer:
$20
Step-by-step explanation:
Of the $100 John earned, $90 was for his hourly charge, which we assume is proportional to the area being mowed.
A lawn with 1/3 the circumference has (1/3)^2 = 1/9 the area, so presumably takes 1/9 of the time to mow. John's hourly charge for the smaller lawn will be $90/9 = $10. Added to his flat fee, he can expect to be paid $20.
_____
The ratio of areas of similar figures is the square of the ratio of any of the linear dimensions. All circles are similar. Circumference is measured in "units" and area is measured in "square units." So, circumference is a linear dimension (units to the first power).

Find the distance between the pair of points: (2,0) and (6,-3)
Answer:
The distance between the pair of points is 5 units.
Step-by-step explanation:
The first thing we must know in order to solve this problem is the distance formula.
[tex]Distance(d)=\sqrt{(x_{2}-x_{1} )^2+(y_{2}-y_{1})^2}[/tex]
We will use the coordinate point (2,0) for our (x₂,x₁) and the coordinate point (6,-3) for our (y₂,y₁). Now, let's plug in these numbers into our formula.
[tex]d=\sqrt{(6-2)^2+(-3-0)^2}[/tex]
[tex]d=\sqrt{(4)^2+(-3)^2}[/tex]
[tex]d=\sqrt{16+9}[/tex]
[tex]d=\sqrt{25}[/tex]
[tex]d=5[/tex]
So, the distance between the two given points is 5 units.

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax and the price of the boxes are the same.
Part A:
Write an equation that tells the price Y for the number of markers X.
Part B:
How much would a box of 64 markers cost?
Answer:
It costs $34 to buy a box of 64 markers.
Step-by-step explanation:
Check whether we are working with a direct proportion, in which case the comparison between the price and the number of markers would be the same.
$ 14 ÷ 24 = $0.58 and $ 7 ÷ 10 = $ 0.70
The prices differ, so they are not directly proportional.
The reason is that both prices include the price of the box, which is the same. This can be thought of as the constant.
If you were to draw a graph of price (on the y -axis) and number of markers (on the x -axis) you would get a straight line where the
y -intercept would be the price of the box and the slope would be the price of a marker. (rate of change of price)
Let's find the slope.
m = (y _2 − y _1 /x _2 − x _1)
m = ($14 −$ 7 /24− 10) = ($ 7 /14 markers) = $ 0.50 / marker
Therefore each marker costs
$ 0.50 or 50 c
the price of 64 markers is:
64 × 0.5 = $ 32.00 ← this is just the markers,
How much does the box cost? Consider
$ 7 for 10 markers at $ 0.50 each
$ 7 − 10 × $ 0.50 = $ 7 − $ 5 = $ 2
The box itself costs $2
The total cost of 64 markers in a box would be:
$ 2 + $ 32 = 34#

Find the center, radius, and intercepts of the circle given below and then sketch the graph of the circle.
x²+(y-1)^2=1
Answer:
Center (0, 1)
Radius 1
x-intercept (0, 0)
y-intercept (0, 0), (0, 2)
Step-by-step explanation:
(1) A circle that has center (a, b) and radius r can have the equation as below:
(x - a)^2 + (y - b)^2 = r^2
Re-write the original equation: x^2 + (y - 1)^2 = 1, we have:
(x - 0)^2 + (y - 1)^2 = 1^2
=> The center of this circle: (a, b) = (0, 1) and the radius r = 1
(2) To find out the x-intercept, we substitute y = 0 into original equation.
=> x^2 + (0 - 1)^2 = 1
=> x^2 + 1 = 1
=> x^2 = 0
=> x = 0
=> x-intercept (0, 0)
(3) To find out the y-intercept, we substitute x = 0 into original equation.
=> 0^2 + (y - 1)^2 = 1
=> (y - 1)^2 = 1
=> y - 1 = -1 or y - 1 = 1
=> y = 0 or y = 2
=> y-intercept (0, 0) and (0, 2)

The tens digit is three less than the units digit. If the digits are reversed, the sum of the reversed number and the original number is 121. Find the original number.
help!!!!!
Answer: 47, 74
Step-by-step explanation:
Let x = units digit
x – 3 = tens digit
Then the number is 10(x – 3) + x and the reversed number is 10(x) + (x – 3)
Equation
The reversed number plus the original number equal 121.
10(x) + (x – 3) + 10(x – 3) + x = 154
10x + x – 3 + 10x -30 + x = 121
22x – 33 = 121
22x = 154

Answer:
[tex] T_{-6, 1} \circ r_{x-axis} (x, y) [/tex]
Step-by-step explanation:
We can see in the picture that the first step is transform ABCD to A'B'C'D'. To do this, ABCD is reflected over the x-axis.
Then, A'B'C'D' should be translated -6 units to the right, that is, on the x-axis; and 1 unit up, that is, on the y-axis.
The composition transformation process is from ABCD to A'B'C'D', then
to A''B''C''D''.
Correct response:
The composition transformation is; [tex]\underline{T_{-6, \, 1} \ \circ \ r_{x - axis}(x, \, y)}[/tex]Process used for finding the composition transformationThe given coordinates of the pre-image ABCD are;
A(3, 5), B(6, 5), C(4, 1), D(1, 1).
The coordinates of the image D'C'A'B' are;
A'(3, -5), B'(6, -5), C'(4, -1), and D'(1, -1).
Therefore, the rule that gives the coordinates of A'B'C'D' from ABCD
(x, y) [tex]\underrightarrow{Rule}[/tex] (x, -y)
The rule for a reflection across the x-axis is; (x, y) [tex]\underrightarrow{r_{x-axis}}[/tex] (x, -y)
Therefore;
The rule that gives A'B'C'D', from ABCD is a reflection across the x-axis.
The rule that gives A''B''C''D'' from A'B'C'D' is the a translation 6 units left and 1 unit up, which is; [tex]\mathbf{T_{-6, \, 1}}[/tex]
Therefore composition transformation that maps pre-image ABCD to
final image A''B''C''D'' is given by a reflection followed by a translation,
with the second transformation coming first in the expression as follows;

What is mortgage?
A mortgage is an agreement between you and a lender that gives the lender the right to take your property if you fail to repay the money you've borrowed plus interest.
Mortgage loans are used to buy a home or to borrow money against the value of a home you already own.
Purchasing a point simply implies negotiating for a lower rate of interest, which involves paying 1% of the loan in lieu of 1% interest reduction.
A point implies a reduction in interest rate by 0.25% while 3 points would reduce the interest rate by 0.75%(0.25%*3)
