Answer:

comic books = 2

magazines = 15

Step-by-step explanation:

Let c = number of comic books bought

Let m = number of magazines bought

He bought 17 items, so

c + m = 17

Comic books cost $4 each and magazines cost $3 each.

He spent $53 on comic books and magazines, so

4c + 3m = 53

Rearrange c + m = 17 to make m the subject:

m = 17 - c

Substitute  m = 17 - c  into  4c + 3m = 53  and solve for c:

4c + 3(17 - c) = 53

⇒ 4c + 51 - 3c = 53

⇒ c = 2

Substitute c = 2  into m = 17 - c to and solve for m:

m = 17 - 2 = 15

Answer:

  63.4

Step-by-step explanation:

x° is an acute angle in a right triangle with the opposite and adjacent sides given. That means the relevant trig relation is ...

  Tan = Opposite/Adjacent

  tan(x°) = 18/9 = 2

The value of the angle is found using the inverse tangent function:

  x° = arctan(2) ≈ 63.4°

  x = 63.4 . . . . . . . rounded to tenths

It can be deduced that the sample space is the collection of the set of possible outcomes in a random experiment.

Your information is incomplete as the graphs aren't provided. Therefore, an overview of the sample space will be given.

A sample space simply means the collection of the set of possible outcomes in a random experiment.

It should be noted that a sample space is usually represented by the symbol S.

Also, the theoretical probability distribution states that the probability of occurence of an event will be equal to the number of the favorable outcomes divided by the total outcomes possible.

Answer:

The important properties of parallelograms to know are:

-Opposite sides of parallelogram are equal (AB = DC).

-Opposite angles of parallelogram are equal (D = B).

-Consecutive angles in a parallelogram are supplementary (A + D = 180°).

-If one angle is 90 degrees, then all other angles are also 90 degrees.

Answer:

162,162,18,18

Step-by-step explanation:

each two opposite angles are equal

since there is an angle equals 162° then the opposite angle equals 162°

since the sum of all angles equal 360°

360-(162+162)= 36

so the sum of the other two opposite angle = 36 then the measure of one angle =36/2 =18°

The initial height of the ball is the y-intercept of the function

The initial height she threw the ball from is 35

The function is given as:

[tex]h(x) = -16x^2 + 3x +35[/tex]

Set x = 0.

So, we have:

[tex]h(0) = -16 * 0^2 + 3*0 +35[/tex]

Evaluate the exponent

[tex]h(0) = -16 * 0 + 3 * 0 + 35[/tex]

Evaluate the products

[tex]h(0) = 0 + 0 + 35[/tex]

Evaluate the sum

[tex]h(0)= 35[/tex]

Hence, the initial height she threw the ball from is 35

Answer:

V' = (-1, -4)

Step-by-step explanation:

the original point V (4, -1) is 4 units to the right and 1 unit down.

now we turn this 90° clockwise (upper right to down to upper left).

that means the right part of the x-axis turns into the bottom part of the y-axis, and the bottom part of the y-axis into the left part of the x-axis.

so, positive x turns into negative y, and the negative y turns into negative x.

therefore, (4 -1) turns into (-1, -4).

The length of a segment is the number of units between its endpoints

The length of YZ is 45 units

The given parameters are:

WX = 11x + 1

YZ = 19x - 31

Lengths WX and YZ are congruent.

So, we have:

[tex]19x - 31 = 11x +1[/tex]

Collect like terms

[tex]19x - 11x = 31 +1[/tex]

Evaluate the like terms

[tex]8x = 32[/tex]

Divide both sides by 32

[tex]x = 4[/tex]

Recall that:

YZ = 19x - 31

So, we have:

[tex]YZ = 19*4- 31[/tex]

[tex]YZ = 45[/tex]

Hence, the length of YZ is 45 units

The number of minutes it will take both of them to iron 11 dress shirt is 90 minutes

Rate is the ratio between two related quantities in different units. Therefore,

Anita iron a shirt in 15 minutes. Therefore,

Michelle iron the same shirt for 18 minutes. Therefore,

Let the time they use to work together = x

Therefore,

1  / x =  18 + 15 / 270

1 / x = 33 / 270

cross multiply

270 = 33x

x = 270 / 33

x = 90 / 11

Both of them will use 90 / 11 minutes to iron a dress shirt

Therefore, 11 dress shirt will be ?

number of minutes to iron 11 dress shirt together = 11 × 90  / 11 = 90 minutes

Answer:

P = 35.98 cm

Step-by-step explanation:

The Perimeter of a shape is the distance around the outside of it. This semi-circle (half circle) has a straight part and the curved part. See image. The straight part is the diameter (distance through the center) it is double the radius that was given, 7 cm.

The circumference of a circle is the perimeter of the whole circle.

C = 2pi•r or pi•d

C = 2pi•7 = 14pi

But you only need half, so 14pi/2 is 7pi.

ADD the straight part and the curved part to get the whole distance around the shape

P = 14 + 7pi

P ~= 35.98 cm
