Kennedy walks 2miles in 15 minutes she want to walk 3 more miles at the rate of speed. Which equation represents how many minutes it would take her to walk 5 miled
Answer:
We know that the equation for the speed is:
Speed = Distance/time.
First, we know that he walks 2 miles in 15 minutes.
distance = 2miles
time = 15 minutes
Then his speed in that interval is:
Speed = (2 mi)/(15 min) = (2/15) miles per minute.
Now, at this same speed, he wants to walk 3 more miles. And we want to find the equation that represents how much time she needs to walk 5 miles (the 2 first miles plus the other 3 miles)
We use again the equation:
Speed = Distance/Time
But we isolate Time, to get:
Time = Distance/Speed
Where:
Distance = 5 miles
Speed = (2/15) miles per min
Time = (5 miles)/((2/15) miles per min) = 37.5 minutes
She needs 37.5 minutes to walk the 5 miles.
Wants to wrap a shipping box shaped like a rectangular prism. The box is 25 inches tall and has a square base with sides that each measure 6 inches. How much paper will she use?
Answer:
672 square inches
Step-by-step explanation:
Given data
Height= 25inches
Lenght = 6 inches
Width= 6 inches
The expression for the area of the box is given as
TSA= 2 (lh + lw+ hw)
TSA= 2(6*25+ 6*6+ 25*6)
TSA= 2(150+ 36+150 )
TSA= 2*(336)
TSA= 672 square inches
The function f(x)=-\x-4/+6 is increasing
through the interval -
A. 6
C. 4
B. -00< x < 4
D. 4
:)
Answer:
Option B
Step-by-step explanation:
Given function is,
f(x) = -|x - 4| + 6
By using a graphing tool we can get the graph of the given function.
From the graph attached slope of the line drawn from [tex]x=-\infty[/tex] to [tex]x=4[/tex] is positive while slope of the line from [tex]x=4[/tex] to [tex]x=\infty[/tex] is negative.
Therefore, segment showing a positive slope will be increasing in the given interval [tex]-\infty<x<4[/tex].
Function 'f' is increasing in the interval [tex]-\infty<x<4[/tex].
Option B will be the correct option.
If x is an even number , the function f(x) = 2x-1 gives an odd number. Identify the set of odd numbers corresponding to this set of even numbers: {0,2,4,6,8}
Answer:
{-1, 3, 7, 11, 15}
Step-by-step explanation:
f(x) = 2x − 1, {0, 2, 4, 6, 8}
f(0) = 2*0 − 1 = 0 - 1 = -1
f(2) = 2*2 − 1 = 4 - 1 = 3
f(4) = 2*4 − 1 = 8 - 1 = 7
f(6) = 2*6 − 1= 12 - 1 = 11
f(8) = 2*8 − 1= 16 - 1 = 15

What is the standard equation of a circle with center (-2,0) and radius 4?
Answer:
B(x+2)^2+y^2=16
Step-by-step explanation:
since you have an x-coordinate only and it is negative and a y coordinate which is 0..basically x will appear positive with its conjecture x^2 and the y value will be independent...y^2...bare in Mind that radius is always squared hence it is 16 instead of 4

alex baked 2.5 batches of brownies. But, 5 brownies burned! if he now has below 15 brownies, how many were in each batch.
Answer:
The number of brownies in each batch is less than 8.
Step-by-step explanation:
Baked batches of brownies = 2.5
Number of burned brownies = 5
Number of brownies left is less than 15
So, the total number of brownies is less than 15 + 5 = 20
Number of brownies in each batch is
n < 20/2.5
n < 8
So, the number of brownies in each batch is less than 8.

For given question,
Angelica used four congruent equilateral triangles.
She constructs a regular tetrahedron using four congruent equilateral triangles.
The length of each edge of tetrahedron = side length of equilateral triangle
So, each edge of tetrahedron measures 14 inches.
Using the formula of area of the regular tetrahedron,
[tex]A=\sqrt{3}\times a^{2} \\\\A=\sqrt{3}\times (14)^{2}\\\\A=1.73\times 196\\\\A=339.08~~in^2[/tex]

Answer:
I= $45
Step-by-step explanation:
Giving the following information:
Edna has $900 in a savings account that earns 5% interest per year.
To calculate the interest earned, we need to use the simple interest formula:
I= P*r*t
P= principal= $900
r= interest = 0.05
t= time= 1
I= 900*0.05*1
I= $45

This formula used in finding the circumference of a circle is C = 2πr
Given the vertices of a triangle ABC below, find the midpoint and length of the midsegment. Give your length in simplified radical form.
Answer:
Midpoint of AC = (-1, 1)
Midpoint of BC = (1, -2)
Length of the midsegment = [tex]\sqrt{13}[/tex]
Step-by-step explanation:
Vertices of a triangle ABC are A(0, 5), B(4, -1) and C(-2, -3).
Midpoint of segment AC = [tex]\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}[/tex]
= [tex](\frac{0-2}{2},\frac{5-3}{2})[/tex]
= (-1, 1)
Midpoint of BC = [tex](\frac{4-2}{2},\frac{-1-3}{2})[/tex]
= [tex](1,-2)[/tex]
Length of the mid segment = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
= [tex]\sqrt{(-1-1)^2+(-2-1)^2}[/tex]
= [tex]\sqrt{4+9}[/tex]
= [tex]\sqrt{13}[/tex]
