Answer:
20% of 30 < 30% of 40
Step-by-step explanation:
Find 20% of 30
20/100 = x/30
Cross multiply
20 × 30 = 100 × x
600 = 100x
Divide both sides by 100
6 = x
Find 30% of 40
30/100 = x/40
Cross multiply
30 × 40 = 100 × x
1200 = 100x
Divide both sides by 100
12 = x
Compare the two answers:
6 and 12
6 < 12
trigonometry, find the missing side(s)
Answer:
x = 8.92 units
Step-by-step explanation:
From the triangle given in the picture,
Missing side of the triangle is the opposite side of the angle measuring 28°
And hypotenuse measuring 19 units has been given.
So, we will use sine ratio for the given angle.
sin(28°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(28°) = [tex]\frac{x}{19}[/tex]
x = 19sin(28°)
x = 8.92 units

Question
( 10 + 5x )7
Lets solve this easily.
So, basically, 10 + 5x is 15 but we still didn't
get rid of the x so therefore it's still 15x and then there's 7 so we multiply 15 x 7 giving us 105x.
Hence, the answer is.
(C), 70 + 35x is the answer.

If the two lines below are perpendicular and the slope of the red line is -7,
what is the slope of the green line?
Answer:
1/7
Step-by-step explanation:
Formula for 2 perpendicular lines: m1 * m2 = -1,
where m1 is gradient of 1st line and m2 is gradient of 2nd line
Application:
-7 * m2 = -1
m2 = 1/7

Step-by-step explanation:
At an amusement park, the cost of an adult's ticket is $22.50, and the cost of a child's ticket is $12.50. A group of 10 people purchased tickets for the amusement park, and paid a total of $155.00, excluding tax. How many children were in the group? How many adults were in the group?
Answer:
is there any more information you could give?
Step-by-step explanation:
**i promise to provide a real answer**
Answer:
7 children and 3 adults
Step-by-step explanation:
We should set up a system of equations for this problem, so let's say that:
x represents the number of children
y represents the number of adults
We know there is a total of 10 people, so:
x + y = 10
We also know that each adult had to pay $22.50 and each child had to pay $12.50. Their total amount paid is $155.00, so:
12.50x + 22.50y = 155.00
Simplifying this a bit:
12.5x + 22.5y = 155
Now, we can use the substitution method to solve this system of equations:
x + y = 10
y = 10 - x
12.5x + 22.5y = 155
12.5x + 22.5 (10 - x) = 155
12.5x + 225 - 22.5x = 155
12.5x - 22.5x = 155 - 225
-10x = 155 - 225
-10x = -70
x = [tex]\frac{70}{10}[/tex]
x = 7 children
Now we substitute back into the system of equations:
x + y = 10
7 + y = 10
y = 10 - 7
y = 3 adults
EFGH is a parallelogram. Find the measure of FG and EG
Answer:
FG = 44
EG = 80
Step-by-step explanation:
For FG:
1) 5z - 16 = 3z + 8
2) 5z = 3z + 24
3) 2z = 24
4) z = 12
5) 3(12) + 8 = 44
For EG:
1) 2w + 22 = 4w + 4
2) 2w = 4w - 18
3) -2w = -18
4) w = 9
5) 4(9) + 4 + 2w + 22 = 80
Please i need helpppp
Answer:
Step-by-step explanation:
A line can be defined by any two points on the line andhas the form
y=mx+b
Where m=slope and b=y intercept (value of y when x=0)
Slope is defined as
m=(y2-y1)/(x2-x1), we have points (0,7) and (1,4)
m=(4-7)/(1-0)
m=-3/1
m=-3 so the line is thus far
y=-3x+b, since we have the point (0,7) we know that b=7 so the line is
y=-3x+7

A y = 2x + 3
© y=-3x + 3
B y = - 2x + 2 / 2
D y = - 2x + 3
Answer:
D
Step-by-step explanation:
The line intercept y axis in (0,3), so in the generic equation y= mx + b, b must be 3. The line is also decreasing, so m must be negative
We have two options: B and D
If we try to put y=0 in these equations we have:
-1/2x + 3 = 0
Let’s solve the equation
-x + 6 = 0
x -6 = 0
x = 6
Checking the graph we notice that the line doesn’t intercept x axis in (6,0), so option B is wrong
For be sure, let’s try the same with option D
-2x + 3 = 0
-2x = -3
x = 3/2
This time is correct, so D is the right answer
