What is the unit rate at which the boy walked?

Answer:

What

Step-by-step explanation:

Answer:

$4.5

Step-by-step explanation:

Let the amount of money

Maria had = x

Nick had = y

All together Maria and Nick had $12.

= x + y = 12

x = 12 - y

After Maria spent 30% of her money and Nick spent 50 % of his money, Maria and Nick were left with the same amount.

30% of x = 50% of y

30/100 × x = 50/100 × y

0.3x = 0.5y

We substitute 12 - y for x above

0.3(12 - y) = 0.5y

3.6 - 0.3y = 0.5y

3.6 = 0.5y + 0.3y

3.6 = 0.8y

y = 3.6/0.8

y = $4.5

Therefore, in the beginning, Nick originally had $4.5

Answer:

1/4 ( x + 12 ) = 2 : x = -4

Step-by-step explanation:

4 x 1/4 (x + 12 ) = 2 x 4

x + 12 = 8

x + 12 - 12= 8 - 12

x = -4

The meter reading in ccf

The question is incomplete, as the  meter readings is not given. So, I will solve using an assumed value for the meter readings.

Let

[tex]x\ m^3 \to meter\ readings[/tex]

The readings in ccf is:

[tex]Reading = \frac{x}{2.832}[/tex]

Now, assume the value of x is 25; The readings will be:

[tex]Reading = \frac{25}{2.832}ccf[/tex]

[tex]Reading = 8.83\ ccf[/tex]

Answer:

[tex]d=10[/tex]

Step-by-step explanation:

Pythagorean theorem:

[tex]d^2+d^2=10\sqrt{2}^2,\\2d^2=200,\\d^2=100,\\d=\boxed{10}[/tex]

Alternative:

[tex]\cos 45^{\circ}=\frac{d}{10\sqrt{2}},\\\frac{\sqrt{2}}{2}=\frac{d}{10\sqrt{2}},\\2d=10\sqrt{2}\cdot \sqrt{2},\\2d=20,\\d=\boxed{10}[/tex]

Alternative (derived from the Pythagorean theorem):

All 45-45-90 triangles have side lengths [tex]x-x-x\sqrt{2}[/tex], where [tex]x\sqrt{2}[/tex] is the hypotenuse. Since this triangle's hypotenuse is [tex]10\sqrt{2}[/tex], its sides are [tex]10-10-10\sqrt{2}[/tex].

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the sector, its area and the angle at the center are not given.

I will solve this using the following illusration

The area of a sector is:

[tex]Area= \frac{\theta}{360} * \pi r^2[/tex]

Assume that:

[tex]\theta = 120[/tex]

[tex]Area = 20[/tex]

The equation becomes

[tex]20= \frac{120}{360} * \pi r^2[/tex]

Simplify

[tex]20= \frac{1}{3} * \pi r^2[/tex]

Take: [tex]\pi = 3.14[/tex]

[tex]20= \frac{1}{3} *3.14* r^2[/tex]

Cross Multiply

[tex]3.14 * r^2 = 20 * 3\\[/tex]

Solve for [tex]r^2[/tex]

[tex]r^2 = \frac{20 * 3}{3.14}[/tex]

[tex]r^2 = 19.11[/tex]

Take square roots

[tex]r = \sqrt{19.11[/tex]

[tex]r = 4.4[/tex]

The radius of the sector of a circle whose area is 20 square units and angle subtends at the center of 120° is 4.4 units.

It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The angle subtends at the center is 120 degrees.

The area of the circle is 20 units.

We know that the area of a circle is given  as

[tex]\rm Area = \dfrac{\theta }{360} \pi r^2[/tex]

Then we have the radius of the sector will be

[tex]\rm r = \sqrt{\dfrac{360*20}{120*\pi}}\\\\\\r = 4.37 \approx 4.4[/tex]

The radius of the sector is 4.4 units.

Answer:

{6, 11, 15}

Step-by-step explanation:

Given the inequality expression 3x-7≥11

Add 7 to both sides

3x-7+7≥11+7

3x ≥ 18

Divide both sides by 3

3x/3 ≥ 18/3

x≥6

Hence the solution to the inequality are the values of x greater than or equal to 6. Hence the required solutions are {6, 11, 15}

Answer:

ASA

Step-by-step explanation:

The ASA (angle side angle) identity states that if 2 triangles share 2 angles and one side in between the angles with each other, they are congruent. Since that is the case here, it is the answer.

Answer:

ASA

Step-by-step explanation:

When you have 2 angles and a side, look and see if the side is between the 2 angles.  What that means is that both angles share the one side.

If that happens, then the solution to congruence is ASA.  I'd be very careful about using SSA. There are exceptions and you should not choose it if you have a choice. Sometimes it works and sometimes it does not.

There are only two possible outcomes in the table that satisfy x ≤ -3; either x = -5 or x = -3. Then

P(x ≤ -3) = P(x = -5) + P(x = -3) = 0.17 + 0.13 = 0.3

Answer:

2x

Step-by-step explanation:

i think this is correct, I'm not 100% sure that it is because the question was a little confusing.

ANSWER:

It would be 6x^3.

PRIOR NOTE:

For this question, it's slightly unclear regarding the formatting with it, but in here I'm going to assume that you've asked what is:

-2x * 3x * -x

when simplified. If it was something else, then the final answer would be different.

BACKGROUND:

To start, when multiplying two terms together, the variable will become squared or to the second power. For example:

2x * 2x = 4x^2

PROCESS:

With this question, it is asking for -2x * 3x * -x, though lets just start with the -2x * 3x part:

-2x * 3x = -6x^2

Now, finishing it off with the * -x part.

-6x^2 * -x = 6x^3

It goes to the third power, because now you have multiplied 3 x's together. The answer is also now positive since a negative * a negative = a positive.

With this, the final answer is 6x^3.
