Answer:
Question 1: 0.18
Question 2: 87.50%
To find a decimal of a percentage always divide by one hundred.
So :
0.18
To find a percentage from a fraction, divide the numerator [top number] by the denominator [bottom number] = 0.875
Take the result and multiply by one hundred. 87.5%

8 Rotate the point (-3,-4) around the origin 180 degrees. State the image of the point.
A (-4,-3)
B (-4,3)
C (4, -3)
D (3, 4)
Answer: D (3,4) trust and believe
brainlyst pls I think I spelt is wrong
Step-by-step explanation:
When a line or shape or point is rotated, it must be rotated around a point.
The image of the point is D. (3,4)
The point is given as:
[tex]\mathbf{(x,y) = (-3,-4)}[/tex]
A 180-degree rotation across the origin is represented as:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
Substitute values for the coordinates of the point (x,y)
[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]
Simplify
[tex]\mathbf{(-3,-4) \to (3,4)}[/tex]
Hence, the image of the point is D. (3,4)

A worker has 25 feet of ribbon to make bows. Each bow uses 2 feet of ribbon. The worker divides 25 by 2 and gets 12.5 as an answer.
What does the worker's answer mean in this context?
A. The worker can make 12 bows and have 1 foot of ribbon left.
B. The worker can make 12 bows and have 5 feet of ribbon left.
C. The worker can make 5 bows and have 12 feet of ribbon left
D. The worker can make 1 bow and have 12 feet of ribbon left.
Answer: The answer is because 12 is how many bows the work made and 0.5 is 5 feet of the ribbon left.
The base of a parallelogram is 21 yards. Find the height if the area of the parallelogram is 525 square
Answer:
25 yards
Step-by-step explanation:
A parallelogram is a quadrilateral (a four sided object) with parallel sides
Some of the characteristics of a parallelogram includes :
Opposite sides and angles are congruent . Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). The diagonals bisect each otherArea of a parallelogram = base x height
Area = 525
base = 21 yards
height = ?
525 = 21 x height
divide both sides of the equation by 21 to find the value of the height
525 / 21 = height
height = 25 yards

A person stands 6 feet tall. The distance from the top of their head to the end of their
shadow on the ground is 10 feet. How long is their shadow? Round to the nearest
tenths where necessary.
Answer:
Length of shadow (Base) = 8 ft
Step-by-step explanation:
Given:
Height of man (Perpendicular) = 6 ft
Length from head to shadow (Hypotenuse) = 10 ft
Find:
Length of shadow (Base)
Computation:
Base = √Hypotenuse² - Perpendicular²
Base = √10² - 6²
Length of shadow (Base) = 8 ft

Need help with this question; What is the measure of one leg of a right angle given that the hypotenuse measure 14cm and the other leg measure 8cm? Please help with explanation. I'll mark you as brainiest.
Answer:
11.5 cm
Step-by-step explanation:
The dimensions of a right angled triangle can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
a² + 8² = 14²
a² + 64 = 196
a² = 196 - 64
a² = 132
find the square root of 132
a = 11.5 cm

I need help on 7 and 8!!!!!Find the diameter of each circle. Use a calculator’s value of Pi. Round your answer to the nearest tenth.
Answer:
37.6 in
48.2 yd
Step-by-step explanation:
The are of a circle is given as :
Area = pi(d²) /4
Area = 1110.4in²
1110.4 = 3. 14 * d² / 4
1110.4 * 4 = 3.14 * d²
4441.6 = 3.14d²
d² = 4441.6 /3.14
d² = 1413.8051
d = 37.600
d = 37.6
8.)
Area, A = 1824.7yd²
1824.7 = 3. 14 * d² / 4
1824.7 * 4 = 3.14d²
7298.8 = 3.14d²
d² = 7298.8 / 3.14
d² = 2323.2801
d = sqrt(2323.2801)
d = 48.200
Hence, diameter = 48.2 yd

Find the gradient of the line segment between the points (-4,-5) and (2,-4).
Answer:
1/6
Step-by-step explanation:
The gradient of the line segment is the same as slope
m = (y2-y1)/(x2-x1)
= ( -4 - -5)/( 2 - -4)
= (-4+5)/( 2 +4)
1/6
Answer:
Step-by-step explanation:
Gradient = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]=\frac{-4-[-5]}{2-[-4]}\\\\=\frac{-4+5}{2+4}\\\\=\frac{1}{6}[/tex]
