Answer:
.02 hours
or
1.2 minutes
Step-by-step explanation:
800 meters is .8 kilometers (because there are 1000 meters in a kilometer).
Now just do dimensional analysis.
.8 km 1 hour
-------- x -------- = .02 hours
. 1 36 km
To find minutes, multiply .02 by 60.
(.02)(60)=1.2 minutes

The estimation of the fractions to the nearest whole number is [tex]5\frac{13}{40}[/tex]
How to subtract fractions?
The fractions are in mixed fractions. Let's convert it to improper fraction and do the arithmetic.
Therefore,
[tex]8\frac{1}{5} - 2\frac{7}{8}[/tex]
[tex]8\frac{1}{5}=\frac{41}{5}[/tex]
[tex]2\frac{7}{8} =\frac{23}{8}[/tex]
Therefore,
[tex]\frac{41}{5} -\frac{23}{8} = \frac{328-115}{40} =\frac{213}{40}[/tex]
Hence,
[tex]\frac{213}{40} =5\frac{13}{40}[/tex]

−7x+6, determine the average rate of change of the function over the interval 1\le x \le 61≤x≤6.
Answer:
[tex]0[/tex] (no change)
Step-by-step explanation:
Recall that the average rate of change of a function [tex]f(x)[/tex] over the interval [tex][a,b][/tex] is equal to [tex]\frac{f(b)-f(a)}{b-a}[/tex]:
[tex]\frac{h(b)-h(a)}{b-a}\\ \\\frac{h(6)-h(1)}{6-1}\\\\\frac{0-0}{5}\\ \\0[/tex]
Hence, the average rate of change of the function [tex]h(x)[/tex] over the interval [tex][1,6][/tex] is [tex]0[/tex], or no change.

Lan make 60 cakes. he gives 1/4 of the cakes to Helen. he gives 20 of the 60 cakes to sue. what fraction of the 60 cakes does he have left?
Answer:
5/12
Step-by-step explanation:
1/4 × 60 = 15
He gave 15 cakes to Helen.
He gave 20 cakes to Sue.
20 + 15 = 35
He gave away a total of 35 cakes.
60 - 35 = 25
He has 25 cakes left.
fraction = 25/60 = 5/12

Solve the following inequality for x. -5x < -15x + 40 a. x > -2.00 b. x > 4 c. x < 4 d. x < -2.00
Answer:
c. x < 4
Step-by-step explanation:
-5x < -15x + 40
bring -15x to the left to combine like terms
-5x +15x < -15x + 15x + 40
10x < 40
divided both sides by 10 to get x alone
10x / 10 < 40 / 10
x < 4

f(x)=x^2. what is g(x)?
A. g(x)= 3x^2
B. g(x)= (1/3x)^2
C. g(x)= 1/3x^2
D. g(x)= 1/9x^2
Answer:
See Down Here
Step-by-step explanation:
We want to get g(x) given that we know f(x) and the graphs for both functions. We will see that the correct option is D:
g(x) = (x/3)^2
By looking at the graph we can see that f(x) and g(x) are two quadratic functions, and g(x) is just a dilation of f(x).
This means that:
g(x) = A*f(x)
Where A is a real number.
We know that:
f(x) = x^2
And by looking at the graph, we also know that g(3) = 1.
Then we can write:
g(3) = A*f(3) = A*3^2 = 1
Now we can solve this for A:
A*3^2 = 1
A*9 = 1
A = 1/9
Then we have:
g(x) = (1/9)*f(x) = (1/9)*x^2 = (x/3)^2
So the correct option is D.

Chuck brought $40.00 to the state fair. He bought a burger, a souvenir, and a pass. The burger was 1 /4 as much as the souvenir, and the souvenir cost 2 /3 the cost of the pass. Chuck had $1.50 left over after buying these items.
Answer:
Souvenir = £14
Burger = £3.50
Pass = £21
Step-by-step explanation:
Souvenir = £x
Burger = [tex]\frac{1}{4}x[/tex]
Pass = [tex]\frac{3}{2}x[/tex]
[tex]\frac{1}{4}x + \frac{3}{2}x +x = 40 - 1.5[/tex]

Angle one and two lie on straight line.
this means there sum is equal to 180°
Given :-
angle 1 = 7x angle 2 = x+12so we can say :-
[tex] \angle1 + \angle2 = 180 \degree \\ 7x + x + 12 = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{ \cancel{168} {}^{ \: \: 21} }{ \cancel8} \\ x = 21 \degree[/tex]
so angle one = 7x= 7×21 = 147°
angle two = x+12 = 21+12 = 33°

Answer:
44 degrees
Step-by-step explanation:
angle c = 90 degrees
angle a = 46 degrees

What is the measure of angle A, in degrees?
===========================================================
Explanation:
Let B represent the unmarked angle on the left between angle A and the 145 degree angle.
Angle B and the 145 degree angle form a straight line of 180 degrees
B+145 = 180
B = 180-145
B = 35
Then use the fact that angles A and B form a 90 degree angle
A+B = 90
A+35 = 90
A = 90-35
A = 55
Does anybody know this? A house casts a shadow that is 57 feet long at the same time a girl who is 4.7 feet tall casts a shadow that is 9.4 feet long how tall is the house do not round your answer
Answer:
h = 28.5 ft
Step-by-step explanation:
the 2 situations are similar, that is the triangles formed in both cases are similar.
then the ratios of corresponding sides are in proportion
let h be the height of the house , then
[tex]\frac{4.7}{h}[/tex] = [tex]\frac{9.4}{57}[/tex] ( cross- multiply )
9.4h = 4.7 × 57 = 267.9 ( divide both sides by 9.4 )
h = 28.5 ft

Answer:
Step-by-step explanation:
Let X be par.
Jenny made x-1 strokes
Jérôme made x+4 strokes.
So, we can use the amount of strokes made, but we have to use absolute value brackets ( | | )
|-1| + |4| = 5.
Jérôme made 5 more strokes than Jenny

Step-by-step explanation:
Step 0: retwite the second equation by dividing LHS and RHS by 3.
[tex]x+2y=2[/tex]
Step 1: combine them as the first minus twice the second to eliminate y
[tex]I - 2\times II : 5x+4y -2x-4y=-14-4 \rightarrow 3x=-18 \rightarrow x= -6[/tex]
Step 2a: At this point I would replace the value of x in the second equation to easily solve for y. That will give you [tex]-6+2y=2 \rightarrow y=4[/tex]. I do imagine you're required to use the same method to solve for y even if it's slower so...
Step 2b: Combine them again, taking the first minus 5 times the second to eliminate x:
[tex]I-5II: 5x+4y-5x-10y=-14-10 \rightarrow -6y=-24 \rightarrow y=4[/tex]
