Answer:
Sally's team found 50 balls
Step-by-step explanation:
300 balls are hidden.
300x30%x40%
=36 balls are yellow
Sally's team finds 20% of 36 and 80% of the white balls (300x30%-36).
20%x36+80%x(300x30%-36)
=7 (approximately or else they would've found 7.2 yellow balls) +80%x(90-36)
=7+43 (approximately)
=50

What is the unknown fraction
___ + 5/10 = 58/100
A. 5/100
B. 8/100
C. 63/100
D. 108/100
WILL GIVE BRAINLIEST
Answer: B. 8/100
Let's give 5/10 a denominator of 100 since 58/100 does, so they have common denominators:
5/10 * 10 = 50/100
Now, we can subtract 50/100 from 58/100 to find the unknown fraction:
58/100 - 50/100 = 8/100
This gives us an answer of,
B. 8/100

I have no clue how I’m supposed to do this…
Answer:
Step-by-step explanation:
We will need to rewrite the Pythagorean Theorem
A^2 + B^2 = C^2
Substitute. tIn this case:
18^2 + x^2 = 82^2
Subtract 18^2
x^2 = 82^2 - 18^2
In order to get x alone, take the root:
x = sqrt(82^2 - 18^2)
And solve:
x = 80

Which shape has parallel side i-Ready
You start at (0, 8). You move down 7 units and right 8 units. Where do you end?
========================================================
Explanation:
The "move down 7" means the y coordinate 8 becomes 8-7 = 1
We subtract 7 from the y coordinate.
The "move right 8 units" means we add 8 to the x coordinate to get 0+8 = 8
Therefore, the point (0,8) moves to (8, 1)

How to calculate the length of an arcThe formula for calculating the length of an arc is expressed as;
L = rtheta
where
r is the radius
theta is the subtended angle
Given the following
r = 7/9π
theta = 70 degrees
L = 70/360 * 2 * 7/9π * π
L = 2.98
Hence the length of EF is 2.98

Find the values of x, y, and z. Round to the nearest tenth, if necessary.
Answer:
Step-by-step explanation:
The value of x is 15, y is 5 and z is 17 units in the given triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
First let us find value of y
We know that hypotensue / leg = leg/y
20/10 = 10/y
Apply cross multiplication
20y=100
y=5
Now let us find x value
20-y=x
20-5=x
x=15
The altitude is √5.15= √75
=8.6
Now by pythagoras theorem, we find value of z
x²+75 = z²
15²+75 = z²
225+75= z²
300= z²
z=17.3
Hence, the value of x is 15, y is 5 and z is 17 units in the given triangle.
