Find the area of the parallelogram. pick one of these
30 sq cm
40 sq cm
12 sq cm
17 sq cm
Answer:
The area of the parallelogram is 40.
Step-by-step explanation:
You multiply the base by the height:
4*10= 40
Please help me! I'm struggling!
Answer:
so one thing you can do is to put the standard form into slope-intercept form
so 6x+y= -4 into y=-6x -4
now, you put a point on (0,-4)
(x,y)
now the slope is -6/1 so you rise (go down) -6 points and run (sideways) 1

Step-by-step explanation:
From two cities that are 500 mi apart, two cars left simulaneously moving towards each other. The speed of one car was 10 mph greater than the speed of the other car. In 5 hours the cars met. Find the speed of each car.
Given:
Distance between to cities = 500 mi
Two cars left simultaneously moving towards each other.
The speed of one car was 10 mph greater than the speed of the other car.
They meet in 5 hours.
To find:
The speed of each car.
Solution:
Let x mi/h be the speed of one car.
So, speed of second car = (x + 10) mi/h
Two cars left simultaneously moving towards each other.
So, their relative speed = x + (x+10) = (2x+10) mi/h
We know that,
[tex]Speed =\dfrac{Distance}{Time}[/tex]
On substituting the values, we get
[tex]2x+10=\dfrac{500}{5}[/tex]
[tex]2x+10=100[/tex]
[tex]2x=100-10[/tex]
[tex]2x=90[/tex]
Divide both sides by 2.
[tex]x=\dfrac{90}{2}[/tex]
[tex]x=45[/tex]
Now,
Speed of one car = 45 mi/h
Speed of other car = 45+10
= 55 mi/h
Therefore, the speeds of two cars are 45 mi/h and 55 mi/hr.

2x -14 = -9 answer for this equation
Answer:the exact form is x=5/2 if its wrong then its probably wrote in a different way
Step-by-step explanation: Move all terms that don't contain
x
to the right side and solve.
Answer:
x= 2.5
Step-by-step explanation:
Simplifying
2x + -14 = -9
Reorder the terms:
-14 + 2x = -9
Solving
-14 + 2x = -9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '14' to each side of the equation.
-14 + 14 + 2x = -9 + 14
Combine like terms: -14 + 14 = 0
0 + 2x = -9 + 14
2x = -9 + 14
Combine like terms: -9 + 14 = 5
2x = 5
Divide each side by '2'.
x = 2.5
Simplifying
x = 2.5
Write the equation in slope-intercept form for a line which points go through (-2,3), parallel to x=o
Answer:
x = -2Step-by-step explanation:
Line x = 0 is parallel to y-axis
Line parallel to given line is also parallel to y-axis. It passes through point (-2, 3), so its equation is:

Answer:
The answer to #6 is 255
The answer to #7 is the mint milkshake is thicker
The answer to #8 is A is 12 and B is 18
The answer to #9 is A is 33 and B is 15
Missing values:
1. 1:7 , 3:21, 18:126
2. 20:12 , 10/3:2 , 8 1/3:5
3. 42:21 , 6:3 , 48:24
4. 4:10 , 8:20 , 16:40
5. 36:32 18:16
Step-by-step explanation:
#2: The first ratio is shown, which is 5:3. Meaning, that the bottom number (cakes) is multiplied by 5/3 in order to get the top number (pies). We can apply that to the ratio with 12 cakes, 12 multiplied by 5/3 is 20. The next ratio involved 10/3 pies. Since that is the "top" number (see chart), 10/3 need to be multiplied by 3/5 instead of 5/3. By doing that, the number of cakes is 2.
#7: The ratio of milk to ice cream in the mint milkshake is 1.25:4
The ratio of milk to ice cream in the strawberry milkshake is 1.75:5
When the ratios are divided, the quotient for the mint milkshake (0.3125) is LESS than the quotient for the strawberry milkshake (0.35). This means that there is less milk and more ice cream (ratio-wise) in the mint one.

Step-by-step explanation:
8/1=8
8/2=4
8/4=2
2 and 4
Factors are the numbers that can be multiplied together to equal 8, not including the number and/or 1. In this case, the only numbers are 2 and 4, because 2x4=8

The sum of two numbers is 2490 and if 6.5 percent of one no. is equal to 8.5 percent of the other, then numbers are ?? Make sure it’s correct answer pls! 20 points for brainliest (also can u tell me how to mark someone brainliest?)
Answer:
The two number are :
x = 1411
y = 1079
Step-by-step explanation:
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
x + y = 2490..... Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
y = 1079
x + y = 2490..... Equation 1
x = 2490 - y
x = 2490 - 1079
x = 1411

Point T is at (-3, 8). What are the coordinates of T' after R(y-axis) o R(x-axis)?
Given:
Point is T(-3,8).
To find:
The coordinates of T' after [tex]R(y-axis)\circ R(x-axis)[/tex].
Solution:
We know that, [tex]R(y-axis)\circ R(x-axis)[/tex] means the figure reflected across the x-axis then reflected across y-axis.
If a figure reflected across x-axis, then
[tex](x,y)\to (x,-y)[/tex]
[tex]T(-3,8)\to T_1(-3,-8)[/tex]
If a figure reflected across y-axis, then
[tex](x,y)\to (-x,y)[/tex]
[tex]T_1(-3,-8)\to T'(-(-3),-8)[/tex]
[tex]T_1(-3,-8)\to T'(3,-8)[/tex]
Therefore, the required point is T'(3,-8).
