Answer:
90 MPH
30 / (1/3) = 90
Answer:
90mph
Step-by-step explanation;
if an object travels 30 miles in the first part of an hour, and the speed is constant, then we can assume 30*3=90
in the first third, it went 30 mi, in the second it went 30mi, and in the last part it went 30 mi
30+30+30=90
or you could do 30* the denominator (in this case its 3), so 30*3=90
Sorry if this doesn't make sense, hope it helps though!
Jenny takes the temperature of a cold glass of water every minute for her science project, and she will graph her results. If the pattern of temperature change continues, what will the temperature of the water be after 9 minutes?
Minutes Temp. (degrees) (x, y)
1 34 (1, 34)
2 35 (2, 35)
3 36 (3, 36)
4 37 (4, 37)
38°
41°
42°
43°
Answer:
your answer is 9,42
Step-by-step explanation:
This is because if you follow the pattern:
5,38
6,39
7,40
8,41
9,42
so (9,42) is your answer

find an equation of the line that has a y intercept of 5 and is perpendicular to the graph of the line 4x+3y=8.
Answer:
3x-x+2=4
Step-by-step explanation:
You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.
Answer:
y = 3/4x + 5
-3x + 4y = 20
Step-by-step explanation:
In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)
First change that standard form equation to slope-intercept form:
1. 4x + 3y = 8
2. 3y = -4x + 8
3. y = -4/3x + 8/3
Step 1 is given.
In step 2, 4x was subtracted from both sides.
In step 3, both sides were divided by 3.
Slope-intercept form:
y = mx + b
m is the slope and b is the y-intercept.
m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)
b = 5; the y-intercept was stated in the problem
Now, you put it together: y = 3/4x + 5
Standard form:
You can just change the slope intercept form back into standard form by moving the numbers around a bit:
1. y = 3/4x + 5
2. -3/4x + y = 5
3. -3x + 4y = 20
Step 1 is given.
In step 2, 3/4x was subtracted from both sides of the equation.
In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)
Is Frieda’s work correct? Explain how she can check her solution.
z + 22 = 64
z + 22 – 22 = 64 – 22
z = 42
Answer:
Frieda should substitute 42 for z in the original equation, and simplify to see if it is a true statement. 42 + 22 = 64, so her solution is correct

In this question as two straight lines intersect each other
we use vertically opposite angle axiom
so 74 degree = 2x.
then x= 74/2= 37degree
Answer:
Angle 74 degrees and 2x are vertical, so they would have to equal each other.
Note: Vertical angles are congruent meaning they measure the same degrees
So we set up the equation;
74 = 2x
/2 /2
37° = x

D. 5, 5, 8, 8, 9, 0, 0, 3, 3, 9, 1, 5
Answer:
D
Step-by-step explanation:
You have to find a pattern that correlates to one of the options to get the key of the stem and leaf diagram. The pattern is the stem is multiplied by the leaf.
In the first one:
1*5=5
1*5=5
1*8=8
1*8=8
1*9=9

What is the distance between (-8, 5) and (6, 5)?
Enter your answer in the box.
___ Units
Answer:
distance: 14
explanation:
[tex]\sf \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
given:
(-8, 5) and (6, 5)solve:
[tex]\sf \rightarrow \sqrt{(5-5)^2+(6--8)^2}[/tex]
[tex]\sf \rightarrow \sqrt{(0)^2+(14)^2}[/tex]
[tex]\sf \rightarrow \sqrt{14^2}[/tex]
[tex]\sf \rightarrow 14[/tex]
Solution:
We know that:
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
Finding the coordinates
(x₁,y₁) = (-8,5) = x₁ = -8; y₁ = 5(x₂,y₂) = (6,5) = x₂ = 6; y₂ = 5Substitute the coordinates into the distance formula.
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6- (-8)]^{2} +[5-5]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6 + 8]^{2} +[0]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[14]^{2}[/tex]
[tex]\rightarrow \boxed{\text{Distance }=14 \ \text{units}}[/tex]
