Answer:
9.11
Step-by-step explanation:
Given that,
[tex]\dfrac{x}{y}=-3[/tex]
We need to find the value of [tex]\dfrac{x^2}{y^2}+\dfrac{y^2}{x^2}[/tex]
The value of [tex]\dfrac{y}{x}=\dfrac{-1}{3}[/tex]
So,
[tex]\dfrac{x^2}{y^2}+\dfrac{y^2}{x^2}=(\dfrac{x}{y})^2+(\dfrac{y}{x})^2\\\\=(-3)^2+(\dfrac{-1}{3})^2\\\\=9+\dfrac{1}{9}\\\\=9.11[/tex]
So, the required answer is equal to 9.11.

Amanda and Carly have the same percentage of green marbles in their bags of marbles. Amanda has 4 green marbles and 16 total marbles. Carly has 10 green marbles. How many of Carly's marbles are NOT green?
Answer:
30
Step-by-step explanation:
They both have the same percentage of green marbles, Amanda has 16 total marbles, 4 of them are green. So 25 percent of her marbles are green. If 25 percent of Amandas marbles are green, 25 % of Carlys marbles are green too. Carly has 10 green marbles, if 10 is 25 percent of the total amount then the total amount if 40, minus 10 from 40 because we only want the non green ones and the answer is 30. :)
How many square feet of outdoor carpet will we need for this hole?
Answer:
42 sq ft
Step-by-step explanation:
First, I will do the small triangle on the right.
2 x 3 = 6
6/2 = 3 sq ft
Next the large rectangle.
11 x 3 = 33 sq ft
Next the large triangle on the left.
3 x (11-7)
3 x 4 = 12
12/2 = 6 sq ft
Add them all together.
6 + 33 + 3 = 42

Find the diameter of a circle with a circumference of 27 centimeters. Use 3.14. Round to the nearest tenth.
Answer:
The diameter of the circle is 5.6 cm
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle and clear d:
c = circumference = 27cm
d = diameter
π = 3.14
c = π * d
d = c / π
we replace with the known values
d = 27cm / 3.14
d = 5.599
The diameter of the circle is 5.599 cm
round to the nearest tenth
d = 5.599 cm = 5.6 cm
The diameter of the circle is 5.6 cm

Find the height of a cone with a diamater of 12m whose value is 151 meters cubed, then round it to the nearest meter
Answer:
Height= 4m (nearest meter)
Step-by-step explanation:
[tex]\boxed{volume \: of \: cone = \frac{1}{3} \pi {r}^{2}h }[/tex]
Diameter= 2(radius)
Given that the diameter is 12m,
radius of cone
= 12 ÷2
= 6m
Let the height of the cone be h meters.
[tex]151 = \frac{1}{3} \pi(6^{2} )(h)[/tex]
[tex]151 = 12\pi h[/tex]
[tex]h = \frac{151}{12\pi} [/tex]
h= 4.0054 (5 s.f.)
Thus, the height of the cone is 4m. (nearest meter)
Please help!! I already missed two!
Answer:
30,40,50
Step-by-step explanation:
We use the Pythagorean theorem to find out if they would be sides of a right triangle
the Pythagorean theorem states that the two shorter sides squared added together equal the longest side square
for 30, 40 , 50
[tex]30^2=900\\40^2=1600\\1600+900=2500\\50^2=2500\\2500=2500[/tex]
2500=2500 therefore that is the correct answer
Which number will be closest to 14? A. 13.4 B. 13 1\2 C. 13.08 D. 13 2\5
Answer:
13.08
Step-by-step explanation:
Its the closest
Answer:
13.5
Step-by-step explanation:
Convert fractions to decimals.
13 and 8/100 is 13.08
13 1/2= 13.5
13 2/5= 13.4 (13.4 and 13 2/5 are the same)
So your options are 13.5, 13.4, 13.08.
Round decimals up or down. When rounding to the nearest hundredth (50 and above rounds up, below fifty rounds down. Ex. 13.5 (13.50) rounds to 14 whereas 13.4 (13.40) and 13.08 round back down to 13)

Write the equation of the line that passes through points (-4,-1) & (5,3)
Step-by-step explanation:
ax+by+c=0 is the equation of a line
using y-y1=m(x-x1)
m=3+1/5+4=4/9
y+1=4/9(x+4) multiplying through 9
9y+9=4(x+4)
9y+9=4x+16
9y+9-4x-16=0
9y-7-4x=0
9y-4x-7=0
then you have your answer

The red figure is smaller so it is a reduction.
To find the scale factor divide the length of the smaller shape by the length of the larger shape:
9/15 this can be reduced to 3/5
Marsha made 8 identical bags using 3 yards of fabric. How much fabric did Marsha use for each bag?
Answer: ok deku
Araceli would have used 2.25 (or 2 1/4) yards of fabric for each bag.
Step-by-step explanation:
First, you have the 9 bags you are making and they all must be the same because they are identical, so you divide the nine bags by the four yards and I got an answer of 2.25 yards per bag. The answer can also be 2 1/4 as well.
Answer:
3/8 of a yard for each bag
Step-by-step explanation:
3/8 = 3/8 of a yard for each bag
Triangle RST and its image, triangle R’S’T’, are graphed on the coordinate grid below.
Which rotation, using the origin as the center of rotation, transformed RST to R’S’T’?
A. a 90° clockwise rotation
B. a 90° counterclockwise rotation
C. a 45° clockwise rotation
D. a 45° counterclockwise rotation
Answer:
B. a 90º counterclockwise rotation
Step-by-step explanation:
You can tell that it moves 90º and it moves in a counterclockwise direction because from RST to R’S’T’ it moves left to right. That is counterclockwise when you look it up.
Hope this helps!!! :)))))

If a quadratic function has an axis of symmetry of x = 2 and a zero of-1. Which of the
following is the other zero?
The line of symmetry is the center/ middle of the parabola where the curve shifts. Since the line of symmetry is at x=2 and the zero is at x= -1, you have the find the difference between the values which is 3. So the other zero is three the right of the line of symmetry at x= 5.

Answer: 19
Step-by-step explanation:
what is 5% of 30 and what is 25% of 30 and what is the difference?
Answer:
5% of 30 is 1.5
25% of 30 is 7.5
25% is one quarter. 5% is a fifth of a quarter.
Answer:
5% of 30 is = 30 x 0.05 = 1.5
25% of 30 is 30 x 0.25 = 7.5
The difference is 6
Find the distance between the two points rounding to the nearest tenth (if necessary).
(−1,−2) and (5,2)
Answer:
7.2 units
Step-by-step explanation:
To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the given values of (-1, -2) & (5, 2)
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(5 - (-1))² + (2 - (-2))²]
Simplify the parentheses.
d = √[(5 + 1)² + (2 + 2)²]
d = √[(6)² + (4)²]
Simplify the exponents.
d = √[36 + 16]
Add.
d = √[52]
Evaluate the radical.
2√13 or 7.2111
Round the decimal.
7.2 units
