Step-by-step explanation:

Opposite sides of a rectangle share the same side measurements (based on the definition of a rectangle). This means that the perimeter is found as:

P(perimeter)= 2l + 2w

Let:

length (l) = 4

width (w) = 2

Plug in the corresponding numbers tot eh corresponding variables:

P = 2(l) + 2(w)

P = 2(4) + 2(2)

Simplify. First, multiply, then add:

P = (2 * 4) + (2 * 2)

P = (8) + (4)

P = 12

12 will be your perimeter.

~

Check. Since it is given that it is a rectangle, by definition of a rectangle, you will know that opposite sides are congruent, and therefore share the same measurements.

P = 2 + 2 + 4 + 4

P = (4) + (8)

P = 12

12 will be your perimeter.

Answer: I would be a 1/2 chance or 50% chance that my team will go first because there are 2 sides to the coin.

Step-by-step explanation:

Answer:

3/4

Step-by-step explanation:

Since (p, r) lies on the line y = x + b,

we have,

r = p + b -----eq(1)

Since (2p, 5r) lies on the line y = 2x + b,

we have,

5r = 2(2p) + b -----eq(2)

Sub the value of r from eq(1) in eq(2),

5(p + b) = 4p + b

⇒ 5p + 5b = 4p + b

⇒ 5b - b = 4p - 5p

⇒ 4b = -p

⇒ b = -p/4

sub in eq(1)

r = p + (-p/4)

= p - p/4

= 3p/4

⇒ r = 3p/4

⇒ r/p = 3/4

Answer:

3/4

Step-by-step explanation:

We have two lines:

r = p + b     eq(1)

5r = 4p + b   eq(2)

eq(2) - eq(1)

4r = 3p

dividing by 4p

r/p = 3/4

Answer:A=192ft²

Step-by-step explanation:

The area of the trapezoid is 128 feet².

Given,

The height of a trapezoid is = 12 feet

The length of one of the base is = 12 feet

The length of other base is = 20 feet

The formula for the area of the trapezoid is = 1/2 × height of the trapezoid × sum of the parallel bases of the trapezoid

The area of the trapezoid will be = 1/2 × 12 × (12 + 20)

                                                       = 1/2 × 12 × 32

                                                       = 4 × 32

                                                       = 128

Answer: 4/5 = 180/b; b = 225 boys

Answer:

Given that there are 4 boys for every 5 girls, we can set up the following proportion:

4/5 = x/180

where x is the number of boys.

To solve for x, we can cross-multiply:

The total amount for 11 neon bracelets is given by the equation A = $ 2.75

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of 11 neon bracelets be A

Now , the equation will be

The cost of 4 neon bracelets = $ 1

The cost of one neon bracelet = cost of 4 neon bracelets / 4

On simplifying the equation , we get

The cost of one neon bracelet = $ 0.25

Now , the cost of 11 neon bracelets A = 11 x cost of one neon bracelet

Substituting the values in the equation , we get

The cost of 11 neon bracelets A = 11 x 0.25

The cost of 11 neon bracelets A = $ 2.75

Therefore , the value of A is $ 2.75

Hence , the total amount is $ 2.75

The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

and, c= 240/30

c= 8

Answer:

\(\huge\boxed{\sf x =28 \textdegree}\)

Step-by-step explanation:

Given that,

∠IAK = 62°

∠IAK + ∠IAD = 90° (Complementary angles)

62 + ∠IAD = 90°

Subtract 62 to both sides

∠IAD = 90 - 62

∠IAD = ∠ACB (Corresponding angles are equal)

So,

∠ACB = ∠GCJ (Vertically opposite angles are equal)

So,

28° = x°

OR

\(\rule[225]{225}{2}\)

Answer:

28 degrees

Step-by-step explanation:

If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.

--> Angle LAJ is 62 degrees

If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.

We know that in a triangle, there are three angles, and the angle measures combined equals 180.

Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.

--> 180 - 90 - 62 = 28

--> Angle BCA = 28 degrees

Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.

Angle x = 28 degrees

Step-by-step explanation:

QUESTION 7:

We are trying to find angles 1 and 2.

Known angle: 107˚.

In this question, we have 2 parallel lines with a transversal. A transversal is a line that passes through 2 parallel lines making it so that the angles on both sides are exactly the same.

Step 1: Find the measures of all the angles using the one we already know.

I will start with the angle adjacent (right next to) the angle that measures 107˚. As you can see, it is a supplementary angle because both of them form a straight line, or 180˚.

Therefore,

107+x= 180

x= 180-107

x= 73˚

Next, I will find the measure of the angle that is vertical to the one that measures 107˚. Note that angles that are vertical to each other are always identical, or in other words they have the same measure. Hence, the angle "vertical", or opposite to the one that measures 107˚ has to measure 107˚ as well.  You can also tell this is true because they look the same.

Now I'll find the measure of the angle vertical to the one that measures 73˚. As we know, vertical angles are identical, so the one vertical to it is 73˚.  

Here, I'll solve for angles 1 and 2. Like I said earlier, when a transversal crosses through 2 parallel lines, there will be 2 sets of angles that all have the same measurements.  

To solve for angle 1, simply know what angle is right below it, and that is the one that measures 107˚. (If you look at the 2 lines, you will see that both angle sets are essentially duplicates of each other.) Likewise, angle 2 has to be 73˚ because the one under it is also 73˚.

Angle 1: 107˚

Angle 2: 73˚

QUESTION 8:

Again, we have a transversal that passes through 2 parallel lines. One angle measures 95˚.  When there are 3 seperate angles along a straight line,  the one next to the one with the given measurement will be the same as that one.

So angle 3 is 95˚. To find angle 4, find the angle measurement that's vertical to angle 3, which is 95˚. Now, since that angle and angle 4 are supplementary (both form a straight line which is always 180˚), 95+x= 180.

(x stands for angle 4)

x+95= 180

x= 180-95

x= 85

Angle 4= 85˚.

QUESTION 9:

ANGLE 5: 49˚

When there is a transversal, there are 2 identical pairs of angles. Therefore, angle 5 must be 49˚.

ANGLE 6: 131˚

angle 5 and angle 6 form a straight line which means they are supplementary angles. Therefore, both angles must add up to 180˚. So 49+x= 180

x= 180-49= 131

(x stands for angle 6)
