Answer:

$345 : whichever is closest

Step-by-step explanation:

Pants were $20 each and she bought 9 of them so multiply:

9x20=180

She paid $180 for 9 pants.

Shirts cost $15 each and she bought 11 of them so Mulitply:

15x11=165

She paid $165 for 11 shirts

Add both totals from pants and shirts

165+180=$345

Answer: 350

Step-by-step explanation: I dont really now how but 345 is close to 350 and my learning app says so.I'M really bad at math but if get this questoin an Modymax than the awsnser is 350.

Answer:

Domain: 0 ≤ x ≤ 5

Range: 4 ≤ y ≤ -1

Step-by-step explanation:

Since the graph is not infinite and ends in two points, the domain and range are also not infinite where there is a range of numbers that the domain and range of the graph fall into. Hope this helps!!

Answer:

BC ≈ 10.4 mm(1 decimal)

Step-by-step explanation:

The question forms a right angle triangle. The angle BAC = 90°. The side AB = 7.3 mm and the side CA = 7.4 mm. The length of BC can be solved below.

AC = opposite side = 7.4 mm

AB = adjacent side = 7.3 mm

BC = hypotenuse = ?

Using pythagoras theorem we can find the longest side which is the hypotenuse

c² = a² + b²(pythagoras formular)

where

c = hypotenuse side

BC² = 7.4² + 7.3²

BC² = 54.76 + 53.29

BC² = 108.05

square root both sides

BC = √108.05

BC = 10.3947101931

BC ≈ 10.4 mm(1 decimal place)

Answer:

BC = 15

Step-by-step explanation:

Because of parallel lines, AD and BE, triangles ADC and BEC are similar.

In similar triangles, the lengths of corresponding sides are proportional.

AC/BC = DC/EC

We see that AC = AB + BC = 3 + BC

Also, DC = DE + EC = 2 + 10 = 12

(3 + BC)/BC = 12/10

(3 + BC)/BC = 6/5

Cross multiply.

5(3 + BC) = 6BC

15 + 5BC = 6BC

15 = BC

BC = 15

Answer:

see explanation

Step-by-step explanation:

cos F = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{FD}{EF}[/tex] = [tex]\frac{5}{13}[/tex]

sin F = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{ED}{EF}[/tex] = [tex]\frac{12}{13}[/tex]

tan F = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{ED}{FD}[/tex] = [tex]\frac{12}{5}[/tex]

Answer:

$13,260

Step-by-step explanation:

B = 3000(1 + 0.14)t = 3(1.14)t

Plugging in 3 for t, we get B = 3000 * 1.14 * 3 = 10,260. This is just the interest though. We still have to add back the original $3,000, and when we do so, we get 3000 + 10260 = $13,260. Hope this helps!

Answer:

4444.63

Step-by-step explanation:

B = 3000(1 +0.14)^3

B = 3000(1.14)^3

B =4444.632 or 4444.63

Answer:

CBD = 82°

Step-by-step explanation:

From the chords relations in a circle, we have that when two chords intersects, we have the following angles:

CBF = DBE =  (1/2) * (arc(CF) + arc(DE))

CBD = FBE = (1/2) * (arc(CD) + arc(EF))

So, using the second equation to find the value of the angle CBD, we have that:

CBD = (1/2) * (100 + 64)

CBD = (1/2) * 164

CBD = 82°

Answer:

254.34[tex]inches^2[/tex]

Step-by-step explanation:

The formula for the area of a circle is : [tex]\pi*radius^2[/tex]

The radius is the length from the side to the centre.

Pi=3.14

In order to work out the area you would first need to work out the radius. You can do this by dividing the diameter of 18 by 2, this gives you 9. This is because the radius is half of the diameter.

Now that we have worked out the radius the next step is to work out the area. You can do this by multiplying pi by the radius of 9 squared, this gives you 254.34 inches squared.

1) Divide 18 by 2.

[tex]18/2=9inches[/tex]

2) Multiply pi by 9 squared.

[tex]\pi*9^2=254.34inches^2[/tex]

Answer:

x= 100º

y= 260º

Step-by-step explanation:

x= 180º-42º-38º

x= 100º

y= 360º-100º

y=260º

(I'm not sure if it's right, but I hope I helped :) )

Answer:

x =80°

y = 280°

Step-by-step explanation:

Given: [tex] AB \parallel CD[/tex]

Extend segment CE in the direction of E in such a way that it intersects ray AB at point say P.

[tex]\therefore m\angle APE = m\angle ECD..(Alternate\: \angle s)\\

\because m\angle ECD = 42°\\

\therefore m\angle APE = 42°\\[/tex]

So, x° would be the exterior angle of [tex] \triangle AEP.[/tex]

Hence, by remote interior angle theorem of a triangle, we have:

[tex]x = 38° + 42°\\

\huge\purple{\boxed{x = 80° }}\\\\

y = 360\degree - 80\degree\\

\huge\red{\boxed{y= 280\degree}}[/tex]

Answer:

i used photomath so it should be right

Answer:

For y=x-3. (0,2) the equation is y=x+2

For y=3-x. (0,2) the equation is y=2-x

For y=3x+1. (0,3) the equation is y=3x+3

For y=-1/2x+4. (0,1) the equation is y=-1/2x+1

Step-by-step explanation:

How I got my answers:

For y=x-3: the gradient is 1 because we do not have anything before x.

For the points given for example (0,2) x is zero  and y-intercept is 2. same for the rest of the points.

Now you can write your equation in the form y=mx+b

where m is your gradient, and b is the y point. So you say y=1x+2 for the first one. Do the same for the rest. Remember 1x is the same as x so you can leave out 1.

You can comment if you did not understand my explanation because this explained how you can do it.

Answer:

x=2 x=-4

Step-by-step explanation:

x2+2x−8=0

Step 1: Factor left side of equation.

(x−2)(x+4)=0

Step 2: Set factors equal to 0.

x−2=0 or x+4=0

x=2 or x=−4

Answer:

x=2 or x=−4

Answer:

x=2 or x=-4

Step-by-step explanation:

ax^2+bx+c=0

when solving this equation you should find two numbers that if we multiply them we get c and when we subtract them we get b so in this equation we get 2 and -4

Answer:

30 inches/4=7.5 inches

Step-by-step explanation:

Answer:

7.5 inches

Step-by-step explanation:

Since we need 4 magnets and we use 5/6 yards, it is easier to convert 5/6 yards into inches first. One yard=36 inches, so we used overall of 30 inches for every magnet. Simply divide 30/4 to get 7.5 inches

[tex]\frac{4}{3} \\1.333333[/tex]

Step-by-step explanation:

Answer:

27:1

Step-by-step explanation:

If the dimensions of the original pyramid are tripled then the ration between the new, larger pyramid and the old one would be 27:1 . This can be calculated by first calculating the volume of a pyramid and then doing the same but with dimensions 3 times the old one. Then divide the volume of the new one with that of the old one.

Volume of Pyramid = [tex]\frac{length * width * height}{3}[/tex]

Volume Pyramid 1 = [tex]\frac{3*3*3}{3}[/tex] = 9

Volume Pyramid 2 = [tex]\frac{9 * 9 * 9}{3}[/tex] = 243

243/9  =  27/1 or  27:1

Answer:

The new volume is 27 times the original volume.

Answer:

1.20x + 2.5 ≤ 20

Step-by-step explanation:

This would be the best inequality to use.

How much Cups She Can Buy

x is the ammount of cups so we will solve for x

Subtract 2.5 from both sides

1.20x + 2.5 -2.5 ≤ 20 - 2.5.

1.20x ≤ 17.5

Divide both sides by 1.20

1.20x/1.20 ≤ 17.5/1.20

x ≤ 14.5833...

She can buy 14 cups

Step-by-step explanation:

Step 1:  Make an equation

20 ≥ 2.50 + 1.20x ← Best inequality

Step 2:  Subtract 2.50 from both sides

20 - 2.50 ≥ 2.50 - 2.50 + 1.20x

17.5 ≥ 1.20x

Step 3:  Divide both sides by 1.20

17.5 / 1.20 ≥ 1.20x / 1.20

14.583... ≥ x

Answer: The max amount of full yogurts that she can buy is 14

Answer:

A. i think

Step-by-step explanation:

because it can't be E. (there is no 3 in-between the circle) And it can't be D. Because there isn't a 16 inbetween the circle and plus etc! and it could be C. also, because it is 4 and 4 is in-between the circle but, the difference between the answer A and C is the plus sign or the minus sign so let's think about that, it could be A or C............A. says (x-3)2 + (y-3)2=4 that seems correct and C. says (x+3)2 + (y+3)2 = 4.......we do not add in this case so it is definitely A. :)

Answer:

(x − 3)2 + (y − 3)2 = 4

Step-by-step explanation:

Answer:

1500p

Step-by-step explanation:

The spinner A has 4 possible values, and the spinner B has 3 possible values, so the total number of possibilities for both spinners is the product of these number of possibilities:

4 * 3 = 12

From these 12 possible pair of values, the ones that give a sum of 7 are:

(6,1), (4,3) and (2,5).

We have 3 cases where the sum is 7, so the probability of having a sum of 7 is 3/12 = 25%. Therefore, the probability of not having a sum of 7 is 75%

To find the expected value, we multiply the probability of each case by the value it would give. If the player wins, the school loses 10p (the player paid 20p and earned 30p), and if the player loses, the school wins 20p. So the expected value of 120 games is:

120 * (0.25 * (-10) + 0.75 * (20)) = 1500p

Answer:

x = [tex]\frac{ab}{b+a}[/tex]

Step-by-step explanation:

Given

[tex]\frac{x}{a}[/tex] + [tex]\frac{x}{b}[/tex] = 1

Multiply through by ab to clear the fractions

bx + ax = ab ← factor out x from each term on the left side

x(b + a) = ab ← divide both sides by (b + a)

x = [tex]\frac{ab}{b+a}[/tex]
