Answer:

4

Step-by-step explanation:

Four people will play basketball, so 10 - 4 = 6.

Half as many people will play baseball, and half of 4 is 2, so 6 -2 = 4.

The rest will play soccer, which is 4.

Answer:

25

Step-by-step explanation:

The median of a trapezoid equals one half of the sum of the bases

AC is a median and EB and DF are the bases.

hence AC = 1/2(EB + DF)

We are given that EB = 13 and that AC = 19. And we need to find DF

To do so we plug in what we are given and solve for DF

AC = 1/2(EB + DF)

AC = 19, EB = 13

19 = 1/2(13 + DF)

Now solve for DF

* Multiply both sides by 2*

19 * 2 = 38

1/2(13 + DF) * 2 ( the 1/2 and 2 cancel out and we're left with 13 + DF )

We then have 38 = 13 + DF

* Subtract 13 from both sides *

38 - 13 = 13 - 13 + DF

We get that DF = 25

Answer:

16 direct

17 indirect

Step-by-step explanation:

16.

If it is a direct variation

y/x = constant

4/-2  -2

-8/4 = -2

-12/6 = -2

This is a direct variation

17.

y/x = -1/2 /-2 = 1/4

y/x = -1/-1 = 1

This is not a direct variation

If it is an indirect variation then

yx = constant

-1/2 * -2 = 1

-1*-1 =1

3 * 1/3 =1

This is an indirect variation

Answer:

y = 4x-1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 4x+b

Substitute the point in and solve for b

3 = 4(1)+b

3 = 4+b

3-4 = b

-1 =b

y = 4x-1

Answer:

y = 4x - 1

Step-by-step explanation:

y = mx + b

y = 4x + b

3 = 4(1) + b

3 = 4 + b

b = -1

y = 4x - 1

Answer:

D. 0%

Step-by-step explanation:

The percentage of profit at which one of the products are sold = 30%

The percentage loss at which the other product are sold = 30%

Let x represent the prices of each of the products, we have;

The profit from the sale of the first product = 30% of x = 0.3·x

The loss from the sale of the second product = -30% of x = -0.3·x

The total gain or loss = Profit + Loss = 0.3·x + (- 0.3·x) = 0

Therefore, there is no net loss

The total loss incurred = 0%.

Answer:

III (third) quadrant

Step-by-step explanation:

Answer: Choice B

Quadrant II, because the slope is positive and the y intercept is negative.

===============================================================

Explanation:

The y intercept is -6 which places the graph below the x axis when x = 0. The graph will go uphill as we move to the right (since the slope is positive), so we cut through quadrant 4 and move to quadrant 1 at some point. Going in reverse of this, we go through quadrant 3.

Only quadrant 2 is never passed through or touched at all.

------------

Here's another way to see why this is. Notice that x < 0 is the case for quadrant 2 since we're to the left of the vertical y axis. If x is negative, then so is (2/3)x. Recall that negative times positive = negative.

Adding on -6 to any negative value just gets us in even more negative territory. So ultimately, y is always negative when x < 0.

But if x < 0 leads to y < 0, then we're in Q3 and not Q2. In short, x < 0 will never get us to Q2 no matter what negative x value we pick.

The graph below hopefully visually summarizes and confirms what we discussed so far.

Answer:

[tex]\boxed{ \sf Cuts \ x-axis \ at \ (9,0 ).}[/tex]

[tex]\boxed{ \sf Cuts \ y-axis \ at \ (0,6).}[/tex]

Step-by-step explanation:

We need to graph a linear equation and we need to find the point on which it crosses the x and y axis . The given equation is,

[tex]\sf\longrightarrow 2x + 3y = 18 [/tex]

For graphing it's line we need at least two points . hair we can find out the points on which it cuts the x and y axis and then using those two points we can plot its graph.

Step 1 : Put x = 0 in the equation :-

[tex]\sf\longrightarrow 2*0 + 3y = 18 [/tex]

Simplify ,

[tex]\sf\longrightarrow 0 + 3y = 18[/tex]

Add ,

[tex]\sf\longrightarrow 3y = 18[/tex]

Divide both sides by 3 ,

[tex]\sf\longrightarrow \underline{\purple{ y = 6}}[/tex]

Step 2: Put y = 0 in the equation :-

[tex]\sf\longrightarrow 2x + 3*0 = 18 [/tex]

Simplify ,

[tex]\sf\longrightarrow 2x = 18 [/tex]

Divide both sides by 2 ,

[tex]\sf\longrightarrow \underline {\purple{x = 9}}[/tex]

Hence the line cuts y axis on (0,6) and on x axis at (9,0) . Now these two points plot the graph . [ Graph is in attachment ]

Answer:

[tex]19 = s + p[/tex] and [tex]121 = 7s + 10p[/tex]

Step-by-step explanation:

First we use constraints given by the problem to set up two equations:

We can only have a total of 19 bags, so:

[tex]19 = s + p[/tex]

Then, we want to maximize her sugar load. Using the info on the weight of each bag and the max carrying capacity:

[tex]121 = 7s + 10p[/tex]

Answer:

Step-by-step explanation:

Let the sugar from 7 pound bags be represented by = s

And let the sugar from 10 pound bags be represented by = p

As given, Captain Liz has room for 19 bags of sugar.

This becomes [tex]s+p=19[/tex]      .......(1)

Also given is , she has room for 19 bags of sugar, so equation becomes:

[tex]7s+10p=121[/tex]     ............(2)

Hence, these are the correct equations.

1) 8

2) 6(5x+2y) factor out greatest common factor

3) 10.8 just move over decimal two places to the left.

4) 30t=150? Then t=5kg Im not sure what the last one is asking, but I’m assuming it’s to solve for t.

Answer:

x = 60.6

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan x = 3.9/ 2.2

Taking the inverse tan of each side

tan ^-1 (tan x )=  tan ^-1(3.9/ 2.2)

x=60.57254

To the nearest tenth

x = 60.6

Answer:

You can buy 40 tacos

You have enough money

Step-by-step explanation:

Given

[tex]Amount = \$20[/tex]

[tex]Taco = 20[/tex]

[tex]Unit\ Cost = \$0.50[/tex] --- missing from the question

Required

Determine if you have enough amount

The number of Tacos that $20 can afford is calculated as:

[tex]Tacos = \frac{Amount}{Unit\ Cost}[/tex]

So, we have:

[tex]Tacos = \frac{20}{0.50}[/tex]

[tex]Tacos = 40[/tex]

[tex]40 > 37[/tex] -- i.e. the number of Tacos will go round the 37 students

Hence, you have enough money
