Kiera randomly selected 35% of the eighth grade students in her school and asked them their favorite food in the cafeteria. Of the students surveyed, 60 chose chicken nuggets as their favorite food. Based on her school who would choose chicken nuggets as their favorite food served in the cafeteria?
Answer:
171
Step-by-step explanation:
Percentage randomly selected = 35%
Number of surveyed who chose chicken nugget = 60
To obtain the number who chose chicken nugget based on her school :
number who chose chicken nugget / Percentage randomly surveyed
60 ÷ 35%
60 ÷ 0.35
= 171.42

A fence is to be enclosed around a square park of side 15m. Atleast how many metres of fencing are needed?
Answer: 60 m
Step-by-step explanation:
The park is said to be square which means that all of its sides are equal.
If the fence is supposed to be put around the park, it is an indirect question asking for the perimeter of the square.
Perimeter of a square:
= 4 * length
= 4 * 15
= 60 m

Which postulate proves these two
triangles are congruent?
A. ASA
B. SAS
C. None, not congruent
D. HL
Answer:
it may be B but I think it's C
Step-by-step explanation:
not sure if this is right, but I would say not congruent. it may be sas but in order for it to be sas then the Angle must be in-between the two congruent sides
Both triangles are congruent by (SAS) side-angle-side postulate.
The correct option is B.
What are congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure. These triangles can be slides, rotated, flipped and turned to be looked identical.
Given,
Two triangles
ABC and DEC
AB = DE (Given)
BC = EC (Given)
∠ACB = ∠DCE (Vertical angles at intersection of DB and AE)
By, Side-Angle-side theorem of congruent triangles,
ΔABC ≅ΔDEC
Hence, by side-angle-side (SAS) postulate, both triangles are congruent.

find the length of the third side of the right triangle!!!!
Answer:
8
Step-by-step explanation:
There are two ways to solve this!
1. Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
100 - 36 = b^2
64 = b^2
8 = b
2. Shortcut using 3-4-5 triangles
A 3-4-5 triangle has to do with the ratios of each side.
In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio
Answer:
6:2
Step-by-step explanation:
X share from old ratio is 1/2
Y share from old ratio is 1/3
Z share from old ratio is 1/6
Now, we are told Y retires and that X and Z purchase his shares.
Thus;
Amount X took from Y = 1/2 × 1/3 = 1/6
Amount Z took from Y = 1/6 × 1/3 = 1/18
Thus, new share of X is now; 1/6 + 1/2 = 2/3
New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9
Ratio is now X:Z = 2/3 : 2/9 = 6:2
slope and y-intercept of the graph of 25x -20y =100
Step-by-step explanation:
First, we need to put this standard form into slope-intercept form
To do this you need to move the "y" to all by itself
-25x+25x-20y=100-25x
-20y=100-25x
y=5/4x-5
Answer:
y=5/4x-5
The slope is-5/4 and the -intercept is (0,5)
How to find the slop?
Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.
25x−20y=100
20y = 100 + 25x
20y=100+25x
y = [tex]5 + \frac{5}{4}[/tex]
She concluded that the slope is [tex]\frac{5}{4}[/tex]
and the y-intercept is (0,5).
y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.
The slope is-5/4 and the -intercept is (0,5)
Finding the value of y at x=0 will allow you to locate the y-intercept on a graph. The graph's intersection with the y-axis occurs here.To learn more about slop refer to:
