Everything should add up to 100%. So do
20 + 40 + 10 + 5 = 75

Now subtract 75 from 100

100 -75 = 25

at the toy store, Caleb and his younger brother, Gabe, each used money they had saved to buy Motor Mystery boxes. The convertibles are their favorite cars to get! Out of the 30 cars in Caleb's Jumbo box, 12 were convertibles. Out of the 10 cars in Gabe's Mini box, 4 were convertibles. Did the boxes have the same ratio of convertibles to total cars?
no links please

Answers

Answer:

Yes.

Step-by-step explanation: As you can see the Caleb's Jumbo box's ratio is 12/30, and the Gabe's Mini box's ratio is 4/10. If you divide both the numerator and the denominator by 3 for Caleb's Jumbo box's ratio it becomes:

12/30= 4/10.

So we can see that the boxes have the same ratio.

Yes. If you simply 12/30 it would lead to 4/10 and then 2/5 but you get the point. The answer is yes

Answer:

x = 54°.

Step-by-step explanation:

As we know, angles in a triangle add up to 180 degrees. a right angle is equal to 90 degrees so we know that the right angle is already 90 degrees. Now, we add the other angle we know, 36 degrees, to the 90°. this gives us 126 degrees. to work out angle x we need to 180 - 126. this will give you 54 degrees. We take the 126 degrees away to give us the remaining angle in the triangle.

Answer:

54 degrees

Step-by-step explanation:

If there are 180 degrees in a triangle and one of the points are 36 degrees then you need to figure out how much a right angle is... it is 90 degrees. 36 degrees + 90 degrees = 126 degrees. 180 degrees - 126 degrees = 54 degrees.

The answer for “?” Is 118 degrees

Explanation:

The “118 degrees” or anywhere where the number is at it will always be the same number in the opposite direction. Meaning that the answer would always be the same from the opposite direction from “left to right”, never the same side like “right to right”.

What is the equation of the line parallel to
3x + 2y = 8 and passes through the point
(4, -3)?

Answers

(4,-3)=1,x+y so easy broooooo

The equation of the line which is parallel to3x + 2y = 8 and passes through the point (4, -3) is y = -1.5x  + 3

How are parallel straight lines related?

Parallel lines have same slope, since slope is like measure of steepness and since parallel lines are of same steepness, thus, are of same slope.

How to get the slope intercept form of a straight line equation?

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

[tex]y = mx +c[/tex]

Let the straight line parallel to the line [tex]3x + 2y = 8[/tex] be [tex]y = mx +c[/tex]

Converting first line in slope intercept form, we get:

[tex]3x + 2y = 8\\\\y = -\dfrac{3x}{2} + 4\\\\y = -1.5x + 4[/tex]

Thus, the slope of the first line is -1.5

The second line being parallel to this, will have same slope. Thus, we get[tex]m = -1.5[/tex]

Thus, the equation of the second line is;

[tex]y = -1.5x +c[/tex]

Now, since it passes through (4,-3), therefore, putting x = 4 and y = -3 should satisfy the equation.

Thus, we get:

[tex]y = -1.5x +c\\\-3 = -1.5(4) + c\\c = 6-3 = 3[/tex]

Thus, the y-intercept of this line is c = 3

Thus, the equation of the second line is: y = -1.5x  + 3

Thus, the equation of the line which is parallel to3x + 2y = 8 and passes through the point (4, -3) is [tex]y = -1.5x + 3[/tex]

The graph of this equation is given below.
