Answer:
Step-by-step explanation:
so 30% of the total number of goals shot is 5
30% of what number is 5....turn ur percent to a decimal..." of " is multiply
let the number of shots represent x
0.30x = 5...divide borh sides by 0.30
x = 5/0.30
x = 16.66 shots
The trend line passes through (10,9) and (35,0). Write an equation for the trend line.
Answer: Solution :
Step 1 :
Make a scatter plot of Lily’s running data.
Step 2 :
To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.
Step 3 :
Find the slope of the trend line.
The line passes through points (2, 20) and (4.5, 45).
Use the slope formula.
m = (y2 - y1) / (x2 - x1)
Substitute x1, = 2, y1 = 20, x2 = 4, and y2 = 45.
m = (45 - 20) / (4.5 - 2)
m = 25 / 2.5
m = 10
Step 4 :
Find the y-intercept of the trend line.
Slope-intercept form equation of a line :
y = mx + b
Plug y = 20, m = 10 and x = 2.
20 = 10 · 2 + b
20 = 20 + b
Subtract 20 from both sides.
0 = b
Step 5 :
Use your slope and y-intercept values to write the equation.
Slope-intercept form equation of a line :
y = 10x + 0
So, the equation for the trend line is
y = 10x

Answer:
The blank in the equation is 1.
x = 7 and the vertical angles measure out to 64 degrees.
Step-by-step explanation:
When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.
Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

Im struggling in math rn and i need help with this problem 3 1/4 = 1/2 + w
Answer:
w= 2 3/4
Step-by-step explanation:
First, we need to find what can equal w. So, we can subtract 1/2 form both sides, so one sides has just w and one side has just a number. 3 1/4-1/2= 2 3/4. So w= 2 3/4
Answer:
2 3/4
Step-by-step explanation:
3 1/4 = 1/2 + w
Transfer 1/2 to other side
3 1/4 - 1/2 = w
Solve
w = 2 3/4

Ben sells homemade cards at a craft fair. He wants to earn more than $50 at the fair. He sells his cards for $2 and he has already earned $36. How many cards foes he need to sell to reach his goal? Write and solve an inequality.
Answer:
He must sell 8 cards to reach the minimum goal.
Step-by-step explanation:
Giving the following information:
He wants to earn more than $50 at the fair.
He sells his cards for $2 and he has already earned $36.
First, we need to calculate the money required to reach the minimum goal:
51 - 36= $15
Now, we write the inequality:
2*x >15
x= number of cards sold.
x>15/2
x> 7.5
He must sell 8 cards to reach the minimum goal.

if a number is a natural number, then it is also a whole number inverse
Answer:
I believe you're learning geometry. Anyways, here are examples of natural numbers: 1, 2, 3... Meanwhile, here are examples of whole numbers: 0, 1, 2, 3... Natural numbers are all the positive whole numbers. Whole numbers are quantities that are both positive and neutral, and don't include any fractions or decimals.

Question 1 (25 points)
An isosceles triangle has a base 8.8 units long. If the congruent side lengths have measures to the first decimal place, what is
the shortest possible length of the sides?
4.5
8.9
4.3
Od
17.7
b
С
Answer:
4.5
Step-by-step explanation:
For any triangle, the basic principle for these types of problems is that the sum of the 2 shorter sides has to be greater than the longest side, otherwise it is not a triangle, even if it's equal to the longest side.
So, let's look at the first option. 4.5. Since this is an isosceles triangle and the base is 8.8 units, the other side has to be 4.5 as well. 4.5+4.5=9. 9 > 8.8. So, we can immediately eliminate options 8.9 and 17.7. What about 4.3? Well, 4.3+4.3= 8.6, but 8.6 < 8.8, so 8.6 is wrong. So, the answer is 4.5.
