In the diagram below DE is the midsegment of AABC.
Find the length of DE and BC.
Answers
Answer:
DE = 5
BC = 10
Step-by-step explanation:
ΔAED is a right triangle with legs of 4 and 6/2 = 3
Use the Pythagorean theorem to find DE
[tex]4^{2} + 3^{2} = DE^{2}[/tex]
16 + 6 = 25 = [tex]DE^{2}[/tex]
DE = 5
The midsegment of a triangle is 1/2 the length of the corresponding side.
Therefore, BC = 2 DE = 2(5) = 10 = BC

A rectangle has an area of 40 square units and a perimeter of 26 units. What is the only length and width combo that would
fit these dimensions?
Answers
Explanation: a rectangle doesn’t have even sides so we have to find a set of 2 different numbers that could be multiplied by 2 (which will represent both of its sides) and then added together to get 26.
5 x 2 = 10 and 8 x 2 = 16
10 + 16 = 26
And 5 (being our length) times 8 (being our width) is 40

Explain what it means for x and y to vary directly
Answers
Answer:
(Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

Answer:
Option (4)
Step-by-step explanation:
Input values are always represented by the x values and output values of a function is represented by f(x).
From the table given,
Values under x column are the input values and values under f(x) or gx) column are the output values.
From both the tables, common output values for the same input value (x = 1) are,
f(1) = 3
g(1) = 3
Therefore, Option (4) is the answer.
The input value that produces the same output value for both functions is: D. x = 1
What is a Function?A function is a relation which has exactly one y-value (output value) that corresponds to each x-value (input value) in the relation.
In the function [tex]f(x)[/tex], the input value (x) 1 produces an output value [tex]f(x)[/tex] of 3. Same applies for the function g(x).
Thus, [tex]f(1) = g(1) = 3[/tex]
Therefore, the input value that produces the same output value for both functions is: D. x = 1

Pam ordered a circular hot tub cover with a diameter of 80 inches. Find the area of the hot tub cover.
Answers
Answer:
5026.55in²
Step-by-step explanation:
Area = πr^2
radius (r) is half of the diameter, hence the radius is 40 inches
So after plugging that in, the equation should look like
Area = π(40)^2
A = 1600π ≈ 5026.55
The units for this is in² so just add that in the end
A cube has an edge length of 10 centimeters. What is it’s volume, in cubic centimeters?
Answers
Answer:
volume=360000 cubic cm.
Step-by-step explanation:
V=a^2
A=6 x s^2
Side = 10
6 times 10^2
10^2=100
6 times 100
Area=600
v=Area(600)^2
Answer:
Step-by-step explanation:
The volume of any rectangular prism is
V=xyz, where x,y,z are its dimensions.
A cube is a special case where x=y=z, meaning all sides are the same, so for a cube
V=s^3, and in this case the cube has sides equal to 10cm so
V=10^3 cm^3
V=1000 cm^3
Ursula and Velda live 4 km apart. They leave their homes at the same time, walking towards each other. If Ursula walks at a rate of 400 m/h, and Velda walks at a rate of 600 m/h, how far apart are they 15 minutes before they meet (in m)?
Answers
Answer: 250 m
Step-by-step explanation:
Given
Distance between Ursula and Velda house is 4 km or 4000 m
Ursula walks at the rate of [tex]400\ m/h\ or\ \frac{20}{3}\ m/min[/tex]
Velda walks at the rate of [tex]600\ m/h\ or\ 10\ m/min[/tex]
Time taken by them to cover 4000 m is
[tex]\Rightarrow \dfrac{4000}{400+600}=4\ h\ or\ 240\ min[/tex]
Distance covered by them 15 min before they meet
Ursula [tex]=\frac{20}{3}\times 225=1500\ m[/tex]
Velda [tex]=10\times 225=2250\ m[/tex]
The total length covered by them is [tex]=1500+2250=3750\ m[/tex]
They are [tex]4000-3750=250\ m[/tex] apart before they meet
