Answer:
We have 5 equations where we want to find the value of k. To find the value of k first solve the term that is multiplicating k, and when we know the term, we can divide both sides to isolate k in one side of the equation.
1) 30 = k*(15/4)
To solve this, we can just multiply by (4/15) in both sides, so we get:
30*(4/15) = k*(15/4)*(4/15)
(30/15)*4 = k
2*4 = k
8 = k
2) 360 = k*√36
Here you need to remember that:
6*6 = 36
then √36 = 6
We could just replace that in the equation:
360 = k*6
now let's divide both sides by 6.
360/6 = k*6/6
60 = k
3) 64 = k*(4²)*(2²)
Here we need to remember that:
4² = 16
2² = 4
We can replace these in the equation to get:
64 = k*16*4
and 4*16 = 64
then:
64 = k*64
Now let's divide both sides by 64.
64/64 = k*64/64
1 = k
4) 100 = k*(25)*(4)
Here we know that 4*25 = 100
So replacing that in the equation we get a similar expression to the above one.
100 = k*100
Now let's divide both sides by 100
100/100 = k*100/100
1 = k
5) 6 = k*3
Here just divide both sides by 3.
6/3 = k*3/3
2 = k

pretty sure you multiply the base times the height. But first you have to take out all triangwkes which leaves you with two of them.
so 8x4 for the top one and then 14x4.5 for the bottom one.
then for the triangles the one on the left is 5.6x4
the right one is 4.5x14
then divide both triangles answers into two. That should be the triangle areas. Then add the two triangles pieces together.
once don’t add the squares areas with the triangles and that’s THE AREAAAA

Mary's dog weights 185 pound. Her dog needs to lose between 9 and 15 pounds. Between what two percentages rounded to the nearest whole number, should Mary's dog lose weight with respect to its current weight 185 pounds.
Answers
Answer:Mary' s dog should loose weight between 92%-95%
Step-by-step explanation:
Step 1
Mary's dog current weight= 185 pound
weight to loose =Between 9 and 15 pounds
Loosing 9 pounds , the dog"s new weight will be = 185- 9= 176 pounds
also
Loosing 15 pounds , the dog"s new weight will be = 185- 15= 170pounds
Step 2
Percentage of weight loss to current weight when he looses 9 pounds=
= 176/185 x 100
=0.95 x100=95%
Percentage of weight loss to current weight when he looses 15 pounds=
= 170/185 x 100
=0.9189 x100
=91.89= 92%
Therefore Mary' s dog should loose weight between 92%-95%
Which is the best estimate for the percent equivalent to 3/8? 26% 27% 37% 38%

many miles will Lynnell travel in 4 hours at the same constant speed?
Answers
Answer:
80 mi.
Step-by-step explanation:
There are a couple ways to solve this problem. I will show you one. First, let's find the rate of travel.
D = RT
70 = 3.5R
R = 70/3.5 = 20
Using that speed, we now get
D = 20(4) = 80 mi.

what does this equal y=8x+1
y=6x+3
Answers
Answer:
(1,9)
Step-by-step explanation:
Step 1: Understand what the question is asking you
Assuming the question is asking you to solve for the point of interesection of the linear system
Step 2: Solve
Equate the 2 linear equations to each other and solve for'x'
8x + 1 = 6x + 3
8x - 6x = 3 - 1
2x = 2
[tex]\frac{2x}{2} =\frac{2}{2}[/tex]
x = 1
Sub x = 1 into any of the 2 equation for y
y=8(1)+1
y=8 + 1
y=9
Step 3: Therefore Statement
Therefore the answer to the linear system is (1,9)
The point of intersection for the two equations is (x=1, y=9).
To find the point where the two equations intersect, we can set them equal to each other since they both represent "y." So, we have:
8x + 1 = 6x + 3
Now, let's solve for "x":
8x - 6x = 3 - 1
2x = 2
x = 2/2
x = 1
Now that we have the value of "x," we can find the corresponding value of "y" by substituting "x = 1" into either equation. Let's use the second equation:
y = 6x + 3
y = 6(1) + 3
y = 6 + 3
y = 9
So, the point of intersection for the two equations is (x=1, y=9).
