Answer:

=

1

Step-by-step explanation:

Answer: ∠1 and ∠5

Step-by-step explanation:

You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

Hope this helps :)

Answer:

4

Step-by-step explanation:

The constant rate of change is how much y increases every time x increases by 1. We might be confused because in this table, we see a number of points, but we don't see any consecutive x-values, so it might seem difficult. But no worries!

All you have to do is calculate using the formula, Δy divided by Δx. What does Δy divided by Δx mean?

All we have to do is look at two points. Let's take, for example, (-2, -10) and (2, -8).

-2 and 2 are the x-values of the points and -10 and -8 are the y-values of the points as coordinates are in the format of (x, y).

All we have to do is minus the y-coordinates and then proceed the minus the x-coordinates. The order does not matter, as in you can do either of these ways:

[(-10) - (-8)] ÷ [(-2) - (2)] = -2 / -4 = 1/2

or

[(-8) - (-10)] ÷ [(2) - (-2)] = 2 / 4 = 1/2

So the constant rate of change or the answer is 1/2.

Answer:

4.5 cm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

121.5 pi = 4/3 pi r^3

Divide each side by pi

121.5 = 4/3  r^3

Multiply each side by 3/4

3/4 *121.5 = 3/4 * 4/3  r^3

91.125 = r^3

Take the cube root of each side

(91.125)^ (1/3) = r^3 ^(1/3)

4.5 = r

6*12=72, 72in to feet is 6ft

384/6=64ft

384 divided by 72 (6 times 12) = 5.33 i think

Answer:

D

Step-by-step explanation:

Why A is wrong:

If a friend has $30 in his checking account and he made a purchase of $28, the equation would be:

30-28 = $2, which does not equal zero.

Why B is wrong:

The temperature was zero and went down to negative ten. It went up to 10, not zero. So this is also wrong.

Why C is wrong:

A friend borrowed $20 dollars and promised to return double the amount, $40. The equation for this is:

20 - 40 = -20, which also does not equal zero

Why D is correct:

Income is how much you earn

Expenses is how much you pay.

If both of them are equal, then your income is zero, which is the correct answer.

Answer:

U=2

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra to solve equations, you should use the properties of equality. The properties say that an equation remains true as long as the same thing happens on both sides. For this equation, the property of subtracting should be used; this property states that the same number can be subtracted from both sides. To find U, isolate the variable by subtracting 2 from both sides. This leaves U=2.

Answer:

Possible outcomes: 1a 1b 2a 2b 3a 3b  

Outcomes for spinning a one = 2

1a, and 1b 2/6

Outcomes for spinning an "a" = 3

1a, 2a, and 3a.

1a is already in the first set so we can exclude it. 2/6

2/6+2/6=4/6

There is a 4/6 or 2/3 chance of getting either an a or an 1

Answer:

(d) 1A, 1B, 2A, 2B, 3A, 3B

(e)  2/3 or 66.66% chance

Explanation is below

Step-by-step explanation:

(d) The Total outcomes are 3*2 = 6, because there are 3 numbers and 2 letters.

The outcomes are:

1A

1B

2A

2B

3A

3B

(e) Of the 6 outcomes, 3 of them have A and 2 of them have 1. But one of them has an A and 1, so it is 4 outcomes: 1A, 1B, 2A, and 3A.

So it is 4/6 = 2/3, or 66.66...% chance

Answer:

AC=2.868

Step-by-step explanation:

using pythagoras theorem

take 35 degree as reference angle

hypotenuse =5 , opposite =AC , adjacent=BC

using sin rule

sin 35=opposite/hypotenuse

0.5735=AC/5

0.5735*5=AC

2.8675=AC

2.868=AC

Answer:

[tex]3x = 90 \\ x + y = 90 \\ x + y + z = 360[/tex]

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

[tex]3(x - 2) + 7x = \frac{1}{2} (6x - 2)[/tex]

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

[tex]3x - 6 + 7x = 3x - 1[/tex]

Now, we would shift all x terms to the left and all number terms to the right.

[tex]3x + 7x - 3x = - 1 + 6[/tex]

After simplifying, the final equation would be:

[tex]7x = 5[/tex]

This is a linear equation and it has one solution.

[tex]x = \frac{5}{7} [/tex]

Answer:

x = 5/7
