Answer:
Naomi charges $8 an hour to mow lawns
Step-by-step explanation:
first day // 2 1/2= 2.5 hrs
2nd day // 4 1/4= 4.25 hrs
2.5hrs + 4.25hrs = 54hrs // 6.75hrs = 54hrs
/6.75 /6.75
= 8hrs

Help me find BE please.
Answer:
BE = 6
Step-by-step explanation:
Fact regarding the centroids of a triangle.
On each median the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint, thus
BD = 2DE, that is
4 = 2DE ( divide both sides by 2 )
DE = 2
Thus
BE = BD + DE = 4 + 2 = 6

Keirra wants to buy 12 bagels. She uses partial products to find her total. She says $ 16.80 is close to my estimate of 12 x 1=12, so this total is reasonable. Do you agree with her? Explain your reasoning.
Answer:
$11.40, is the actual price, so no
Step-by-step explanation:
If a bagel is $0.95 cents, then multiply that by 12, that would be $11.40, so no, her total is not reasonable, even if you round $0.95 to a dollar, 12x1 would be 12, so you can't estimate that to $16.80

The value 5 is an upper bound for the zeros of the function shown below.
f(x)= x4 + x3 – 11.x2 – 9x + 18
A. True
B. False
Answer:
The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.
Step-by-step explanation:
Given
[tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex]
We know the rational zeros theorem such as:
if [tex]x=c[/tex] is a zero of the function [tex]f(x)[/tex],
then [tex]f(c) = 0[/tex].
As the [tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex] is a polynomial of degree [tex]4[/tex], hence it can not have more than [tex]4[/tex] real zeros.
Let us put certain values in the function,
[tex]f(5) = 448[/tex], [tex]f(4) = 126[/tex], [tex]f(3) = 0[/tex], [tex]f(2) = -20[/tex],
[tex]f(1) = 0[/tex], [tex]f(0) = 18[/tex], [tex]f(-1) = 16[/tex], [tex]f(-2) = 0[/tex], [tex]f(-3) = 0[/tex]
From the above calculation results, we determined that [tex]4[/tex] zeros as
[tex]x = -3, -2, 1,[/tex] and [tex]3[/tex].
Hence, we can check that
[tex]f(x) = (x+3)(x+2)(x-1)(x-3)[/tex]
Observe that,
[tex]for x > 3[/tex], [tex]f(x)[/tex] increases rapidly, so there will be no zeros for [tex]x>3[/tex].
Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using the equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second y=-16x^2+235x+133
Answer:
Step-by-step explanation:
Given tq equation of the height reached by the rocket as y=-16x^2+235x+133
The velocity of the object at its maximum height is zero
v = dy/dx = 0(at max height)
v =-32x +235
0 =-32x+235
x = 235/32
x = 7.34
Hence the rocket will reach its maximum height after 7.34seconds
Zach lives in Salina, Kansas. Gina lives 45 miles east in Junction City, Kansas. Gina and Zach both leave their houses at the same time, heading east on I-70. Zach drives 65 miles per hour and Gina drives 55 miles per hour. Zach wants to determine how long it will take before he catches up with Gina.
Answer:
4.5 hours
Step-by-step explanation:
Given that Gian lives 45 miles east of Salina where Zach lives.
At the same time, both start driving in the same direction towards the east, Zach drives 65 miles per hour and Gina drives 55 miles per hour.
Let A and B are the initial locations of Zach and Gina respectively, after t hours they meet at point C which x miles east of point B as shown in the figure.
Distance traveled by Gina = BC= x miles
As distance = speed x time, so
[tex]x= 55 \times t \cdots(i)[/tex]
Similarly, distance traveled by Gina = AC= (45+x) miles
As distance = speed x time, so
[tex]45+x= 65 \times t \\\\[/tex]
[tex]\Rightarrow 45+55t= 65 \times t[/tex] [ using equation (i)]
[tex]\Rightarrow 10t= 45 \\\\[/tex]
[tex]\Rightarrow t = 45/10 = 4.5[/tex] hour
Hence, the required time is 4.5 hours.

If 30/t = 18/r, then t/r =
Answer:
30/t = 18/r
30 = 18t/r
30r = 18t
18t = 30r
18t/18 = 30r/18
t = 5/3r
--------------------
30/t = 18/r
30r = 18t/r
30r = 18t
30r/30 = 18t/30
r = 3/5 t
---------------------
r = 3/5t, t = 5/3r
When x = -2 h (x) = |-2x-6|
Answer:
Step-by-step explanation:
A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.
so you must first find what is the x and which one is the y in the function then you will find the answer when you solve the problem

You would do 360-(17x+5)= which would get you that angle of the rest of that. Then u would do take that answer and minus it from 360 which would get your answer
Answer:
90°
17x+5 and 18x are corresponding angles and because we have parallel lines these two angles are congruent.
Step-by-step explanation:
17x+5=18x
5=18x-17x
5=x
17x+5=17*5+5=85+5=90°

Whats the reciprocal of 9/2 and 4/7
Answer:
2/9 and 7/4
Step-by-step explanation:
just flip it
The answers are:
2/9 and 7/2
Step-by-step explanation:
The reciprocal of a number is a special number such that, when multiplied by the original number, gives us 1.
And we know that in fractions, to get from a/b to 1, we should multiply a/b times b/a.
So this leads to the conclusion that the reciprocal of 9/2 is 2/9 and the reciprocal of 4/7 is 7/2.

Tyana has a collection of hoodies and t-shirts. She has 561 pieces of collected clothing in all. The number of hoodies is twice the number of t-shirts. Find the number of each type of clothing she has.
Answer:
187 t-shirts and 374 hoodies.
Step-by-step explanation:
(t is shirts)
561 = t + (2t)
561 = 3t
/3. /3
187 = t
ck:
187 + ( 2 times 187) = 561
187 + 374 = 561
561 = 561
