Answers

Answer:

First box -3, 1

Second box -3, 7

Step-by-step explanation:

If they start at 4 on the y-axis, they can go down to 1 or go up to 7. Then we just add the -3 to the x axis.

Answer:

(-3,7) and (-3,1)

Step-by-step explanation:

You would move the point up or down one (this is because you are moving on the y-axis) which would only change y leaving x alone as -3. This means you would either subtract 3 or add 3 to 4 which gives you 1 or 7.

What is -3x less than 12

Answers

Answer:

[tex]x < 4[/tex]

Step-by-step explanation:

In order to isolate the variable in this linear inequality, we need to get rid of the coefficient that multiplies it.

This can be accomplished if both sides are divided by 3.

3x /3 = 0x

12 /3 = 4

So the asnwer is x = 4 (don't forget the less than sign)

ANSWER = x < 4

The answer is X < 4 hope it helps !

Triangles- Angles & Classifying
Instructions in photo!

Answers

Answer:

[tex]angle Q = about 45\\\\\\angle R= about 19\\\\angle S= about 127[/tex]

Looking at these angles, the type of this triangle is an obtuse triangle.

Step-by-step explanation:

First, sum up all the angles to 180 (because any triangle's angles sum up to 180).

[tex]4x-17 +x+5+10x-4 = 180[/tex]

Next, combine like terms:

[tex]15x -16 = 180[/tex]

Solve:

[tex]15x = 196\\\\x = 196/15[/tex]

After that, plug x into the angles equations

[tex]angle Q \\4*(196/15) -7 = about 45\\\\\\angle R\\196/15 + 6 = about 19\\\\angle S\\10*196/15 - 4 = about 127[/tex]

Since 127 is obtuse, this triangle is obtuse.

I hope this helps, but I am unsure if it is correct.

Answer:

Volume of triangular prism = 126

Volume of composite figure = 462

Step-by-step explanation:

The volume of a triangular prism is base area x height

Here the base of the triangular prism has sides 7(the vertical side) and 6(the horizontal side). The are of this base = area of the triangle = 1/2 * 7 * 6 = 21

(Area of a triangle is 1/2 x b x h where b is base and h is height)

The volume of the prism is simply this area x width = 21 x 6 = 126

To get the composite figure volume add the volume of the rectangular prism so we get 126 + 336 = 462

Answer:

126 cm³

Step-by-step explanation:

The volume of the triangular prism can be calculated using the formula below:

Volume of prism= base area ×height

Area of base

= area of triangle

= ½ ×base ×height

= ½(6)(7)

= 21 cm²

The height of the triangle is the same as the length of the 7cm side of the rectangle.

In this figure, the height of the prism is 6 cm.

Volume of triangular prism

= 21(6)

= 126 cm³

_______

Area of composite figure

= area of rectangular prism +area of triangular prism

= 336 +126

= 462 cm³

There are 287 basketball fans who plan to go to a game. How many buses will be needed, given that each bus can hold 34 fans?

Answers

Answer:

9 buses will be needed but 9 bus will be empty there will be very small amount of fans in the 9th bus.

9 buses.
Explanation:
We divide the number of basketball fans by the number of fans that can be accommodated by the bus. We get 8.4
Since we cannot cut the bus into 0.4 we add another bus so that everyone will get to go.
Another method is
Multiply 8 buses by 34 fans. We get 272 fans will be able to go to a game.
This means that some fans will be left by the bus but our goal is to have everyone go.
And thus we need the 9th bus to carry the remaining 15 fans

HELPPPP ASAP!!! You toss a coin (heads or tails), then spin a three-color spinner (red, yellow, or blue). Complete the tree diagram, and then use it to find a probability.

1. Label each column of rectangles with "Coin toss" or "Spinner

2. Write the outcomes inside the rectangles. Use H for heads, T for tails, R for red, Y for yellow, and B for blue.

3. Write the sample space to the right of the tree diagram. For example, write "TY" next to the branch that represents "Toss a tail, spin yellow.

4. How many outcomes are in the event "Toss a tail, spin yellow"?

5. What is the probability of tossing tails and spinning yellow?

Answers

The tree diagram that represents the events is an illustration of probability and combination

The tree diagram

To draw the tree diagram, we make use of the following representations:

H for headsT for tailsR for red, Y for yellow, and B for blue.

See attachment for the tree diagram.

The sample space and the outcomes

From the tree diagram, the sample space is as follows:

S = {HR, HY, HB, TR, TY, TB}

The number of outcomes that represents "Toss a tail, spin yellow"

This is represented as: TY

From the sample space above, we have:

TY = 1

Hence, the number of outcomes that represents "Toss a tail, spin yellow" is 1

The probability

We have:

TY = 1Sample size = 6

Hence, the probability of tossing tails and spinning yellow is 1/6
