Carly has averaged four goals per game for the first eight games of the indoor soccer season (which runs for 10 games)
She wants to finish the season with an average of 5 goals per game.
How many goals does she need to score in total in the last two games to achieve this?
Answer:
9
Step-by-step explanation:
i did 8x4 which is 32
and knowing how to do averages i knew the total of the numbers was going to be divided by the amount of numbers, so i knew that it had to add up to 50 because 50/10 is 5.
so i knew i needed 18 more points, 18/2 = 9 so
4(8) + 9(2) = 32 + 18 = 50

What is the area of trapezoid DEFG?
PLEASE SO THIS ASAP!!!
MUST SHOW WORK
Answer:
Area = 35 cm^ 2
Step-by-step explanation:
Area = 1/2(a+b) x h
1/2 (5+9) x 5
= 35 cm^ 2
Answered by G a u t h m a t h
Answer:
A = 35 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂)
where h is the perpendicular height between the bases and b₁, b₂ are the bases.
Here h = 5 , b₁ = 9 and b₂ = 5 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (9 + 5) = 2.5 × 14 = 35 cm²
The slope of the line is-
A)m=-2
B)m=-(1/2)
C)m=1/2
D)=m=2
A point on the line is-
A)(-4,-1)
B)(4,1/2)
C)(1/2,-1)
D)(1,4)
Answer:
C
D
Step-by-step explanation:
Point slope form is written in
y - y1 = m(x - x1)
Where m is the slope and (x1, y1) is a point on the line.
Looking at the values we have m = 1/2 and x1 = 1, y1 = 4.
Therefore the slope is 1/2 and the point is (1,4)

Step-by-step explanation:
[tex](-3, -3) = (x_1,y_1)\\m = 1/2\\\\y-y_1=m(x-x_1)\\\\y -(-3)=\frac{1}{2} (x -(-3)\\\\y+3 = \frac{1}{2}(x+3)\\\\ y+3 = \frac{1}{2} x+\frac{3}{2}\\\\ y = \frac{1}{2} x +\frac{3}{2} -3\\\\y = \frac{1}{2} x - \frac{3}{2}[/tex]
Answer:
[tex]\Large \boxed{\mathrm{Option \ B}}[/tex]
Step-by-step explanation:
y = mx + b
(slope intercept form of a line)
m = slope
b = y-intercept
y = 1/2x + b
Only three options have a slope of 1/2.
y= 1/2x + 3/2
y= 1/2x - 3/2
y= 1/2x - 1/2
The line crosses the point (-3, -3), x = -3 and y = -3.
-3= 1/2(-3) + 3/2
-3= -3/2 + 3/2
-3 = 0
This is false.
-3= 1/2(-3) - 3/2
-3 = -3/2 - 3/2
-3 = -6/2
-3 = -3
This is true.
-3= 1/2(-3) - 1/2
-3 = -3/2 - 1/2
-3 = -2
This is false.

Answer:
s = 5
Step-by-step explanation:
9* number of scarves in each box after removing 1 scarf = 36
9 *(s -1) = 36
9s - 9 = 36 {Distributive property}
9s = 36+ 9 {add 9 to both sides}
9s = 45
s= 45/9 {Divide both sides by 9}

Tony owns a shop that sells mobile phones and laptops. The retail price of a mobile phone is $240, and it will include a sales tax of 15% on the retail price. If the shop owner offers a discount of $46 off the final price including the sales tax, what is the percent decrease for the price of the mobile phone? A 20% B 15% C 19.17% D 16.67%
Answer:
Percent decrease in mobile = 19.17 % (Approx)
Step-by-step explanation:
Given:
Retail price of mobile phone = $240
Sales tax = 15% on retail value
Total discount including sales tax = $46
Find:
Percent decrease in mobile
Computation:
Cost of mobile = $240(85/100)
Cost of mobile = $204
Percent decrease in mobile = [$46 - 15%]204
Percent decrease in mobile = 19.17 % (Approx)
Al’s Produce Stand sells 6 ears of corn for $1.50. Barbara’s Produce Stand sells 13 ears of corn for $3.12. Write two equations, one for each produce stand, that model the relationship between the number of ears of corn sold and the cost.
Answer:
6n = 1.50
and
13n = 3.12
Step-by-step explanation:
Here in this question, we are interested in writing equations that relate the number of ears of corn sold and the cost.
For Al’s produce stand, let the price per corn sold be n
Thus;
6 * n = 1.50
6n = $1.50 •••••••(i)
For the second;
let the price per corn sold be n;
13 * n = $3.12
-> 13n = 3.12 •••••••••(ii)

Answer:
LM = 2(MP)
Step-by-step explanation:
The radius KN is perpendicular to LM meaning that the line is split in half at the crossing. Review properties of circles to see why this is true.
Since we know this, we can say LM = LP + MP. And LP = MP.
So we can say LM = 2(MP).

What is the possibility that a red or green marble will be selected from a bag containing 9 red marbles, 6 blue marbles , 7 green marbles and 11 yellow marbles
Answer:
16/33
Step-by-step explanation:
We have a bag of :
9 red marbles
6 blue marbles
7 green marbles
11 yellow marbles
Total number of marbles = 33 marbles.
The possibility that a red or green marble will be selected from a bag
P( Red or Green) = P(Red) + P(Green)
In the question we are not told if it is with replacement or without. We do both
With replacement
P( R or G) = P(Red) + P(Green)
P(Red)= 9/33
P(Green) = 7/33
= 9/33 + 7/33
= 16/33
Therefore, the possibility that a red or green marble will be selected from a bag is 16/33
Do I just set it equal to 180? or am i wrong
Answer:
AB=18 units.
Step-by-step explanation:
So, one of the angle measures is 6x. Since the shape is an equilateral triangle, this means that all the angles measure 6x. In other words, the total measure of the three angles is 6x+6x+6x=3(6x) or 18x. Recall that a triangle has a total interior angle sum of 180. Therefore, set 18x to 180 and solve for x:
[tex]18x=180\\[/tex]
Divide both sides by 18:
[tex]x=10[/tex]
Therefore, x is equal to 10.
Now, since this is an equilaterial triangle, all three side lengths are the same. Thus, AB=BC=AC. We know that BC is equal to x+8. Find BC:
[tex]BC=x+8\\BC=(10)+8\\BC=18[/tex]
And since all the side lengths are equivalent, this means that side AB is also 18 units.
Answer:
See below.
Step-by-step explanation:
The 3 angles in the triangle add up to 180 degrees
Also, as all 3 sides are equal, all 3 angles are also equal and each has the value 180/3 = 60 degrees.
So 6x = 60
x = 10.
Now AB = BC = x + 8
Therefore AB = x + 8
= 10 + 8
= 18.
