Rewrite 4/5 using fifteenths
Answer:
12/15
Step-by-step explanation:
The fraction of 4/5 using fifteenths is 10/9.
What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
4/5 using fifteenths
We have to convert the denominator in 15.
So, multiplying the fraction by 3/3
Then, 4/5 x 3/3 = 12 / 15
Hence, the fraction of 4/5 using fifteenths is 10/9.

The length of a triangle is 1 1/8 cm longer than the width. The perimeter is 13 1/4 cm. What are the width and length of this triangle?
Answer: See explanation
Step-by-step explanation:
I think your question should be a rectangle and not a triangle. A triangle has 3 sides and not 2 sides. In order to solve the question, I'm assuming that you wanted to write rectangle.
Note that the perimeter of a rectangle:.= 2(length + breadth)
Let the width be x
Since the length is 1 1/8 cm longer than the width, therefore, the length is 1 1/8 + x.
Therefore, perimeter = 2(1 1/8 + x + x) = 13 1/4
2(1 1/8 + 2x) = 13 1/4
2 2/8 + 4x = 13 1/4
2 1/4 + 4x = 13 1/4
4x = 13 1/4 - 2 1/4
4x = 11
x = 11/4
x = 2 3/4
Therefore, the width is 2 3/4cm
Length = 2 3/4 + 1 1/8
= 2 6/8 + 1 1/8
= 3 7/8cm

What is the equation in point−slope form of the line passing through (1, 2) and (2, 5)?
(5 points)
A.) (y − 2) = −3(x − 1)
B.) (y − 2) = 3(x − 1)
C.) (y − 1) = −3(x − 2)
D.) (y + 2) = 3(x + 1)
Please make sure the answer is correct
Answer:
B
Step-by-step explanation:
First, find the slope by using change in y divided by change in x.
Change in y = 5 - 2 = 3
Change in x = 2 - 1 = 1
This means that the slope is 3/1 = 3.
Then, you put it in the point-slope form so:
(y - 2) = 3(x - 1)

Graph the linear function q(x)=-3x
Answer:
Step-by-step explanation:
the diagram shows a circle drawn inside a square 12cm the circle touches the edges o the square. calculate the shades area. take pi to be 3.142 and write down all the digits given by your calculator.
Answer:
30.89cm³
Step-by-step explanation:
Given that:
Side length, s of square = 12cm
Area of square = s² = 12² = 144cm²
Since the circle touches the edge of tbe square, then the diameter of the circle = side length of square = 12 cm
Area of a circle = πr²
Radius, r = diameter / 2 = 12/2 = 6cm
A = 3.142 * 6^2
A = 3.142 * 36
A = 113.112 cm²
Area of shaded portion = area of square - area of circle
= 144cm² - 113.112cm³
= 30.89cm³

3.Elaine bought a total of 15 shirts and pairs of pants. She bought 7 more shirts than pants. How many of each did she buy.
Answer:
Step-by-step explanation:
1) Make it so that it's easy to solve
3 = -y +2x
18 = y + x (the y cancels out)
21 = 3x (divide both sides by 3 to isolate x)
x = 7 (then you can plug in x and then solve for y)
2) Again, make the problem easy to read
12 = -x + y
27 = 4x + 2y (get rid of either x or y. I am going to get rid of x by multiplying the top equation by four)
48 = -4x + 4y
27 = 4x + 2y (x is canceled out)
75 = 6y (divide both sides by 6 to isolate y)
12.5 = y (then plug in y to find x)
3) 15 = (7 + p) + p -----------------> p represents pants and (7 + p represents shirts because she bought 7 plus pants of shirts)
15 = 7 + 2p
8 = 2p (isolate p by dividing by 2)
p = 4
- Elaine bought 4 pants and 11 shirts.

What are trigonometric ratios?The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given that, a right triangle Δ DEF,
We know that the sine of an angle is the trigonometric ratio of the opposite side to the hypotenuse of a right triangle containing that angle.
Therefore, If D is the reference angle then, sinD = 8/√185
and B is the reference angle then, sinB = 11/√185
Hence, The correct options are (1) and (3)
