Answer:

yes it is correct

Step-by-step explanation:

Answer: Yes You are correct!

Step-by-step explanation:

If a number in the tenths place is greater than or equal to 5 then we round up. Ex: 1.90 would round to 2

If a number in the tenths place is less than or equal to 4 then we round down. Ex: 1.19 would round to 1

Since 8 is in the tenths place we round up. 3.81 would be 4 rounded to the nearest whole number.

You are correct

Answer:

The important clue here is when they say both The girls owe the same amount so what they mean is equate both the functions  

so we get

150 - 20n = 130 - 15n

Now n gives us the number of weeks so solve for n

20n - 15n = 150 - 130

5n = 20

n = 4

Now check your solution  

150-20(4) = 70

130 - 15(4) = 70

So our answer checks out after 4 weeks both girls who their dads the same amount of money .

The Plot of the point (1.5, −3) on the coordinate plane is represented by Red dot in the attached graph.

The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.

The cartesian coordinate plane is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is written as; (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

Given

Point: (1.5, −3)

Required to Plot the point (1.5, −3) on the coordinate plane.

The points can be rewritten as:

x --- f(x)

1 ---- 1

2 --- 2.5

3 ---- 6.25

The data under the x column are the domain of the function.

The equation for the given situation is 5+10.50x=68.

Given that, the parking garage charges an initial fee of 5$.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of hours be x.

Garage charge $10.50 per hour parked. You had to pay $68.

So, equation is 5+10.50x=68

Answer:

The negative numbers do not have square roots. Therefore the question does not have a solution. That is where Julie made a mistake.

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

First, let's take a look at this property:

[tex] \displaystyle \large{ \sqrt{a} \sqrt{b} = \sqrt{ab} }[/tex]

This only works for a and b ≥ 0.

As for a & b < 0 which results in Imaginary Number, we have to convert in 'i' form.

We know that:-

[tex] \displaystyle \large{ i = \sqrt{ - 1} }[/tex]

Thus:

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{3} i \cdot \sqrt{12}i }[/tex]

Then we can multiply 12 & 3 in square root.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36} {i}^{2} }[/tex]

We know that:

[tex] \displaystyle \large{ {i}^{2} = - 1}[/tex]

Convert i^2 to -1

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36}( - 1) } \\ \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - \sqrt{36}}[/tex]

Then evaluate √36 which is 6.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - 6}[/tex]

Therefore the answer should be -6.

Conclusion

Julie cannot use the √a√b = √ab property first because a & b both are < 0 and the property applies for a ≥ 0, b ≥ 0.

Ok, so it's actually pretty easy

First of all, we know that all triangles' angles add up to 180 degrees

Here we can tell that we have one 90 degree angle and another 45 degree angle

Now, we can subtract both of these angles to then finalize that, the missing angle is equal to 45 degrees

Answer:

Blue bottle holds more.

Step-by-step explanation:

Given:

Green Bottle = 8 3/5 = 43/5

Blue Bottle = 8 6/7 = 62/7

Now:

we can write 43/45 as;

43/5 x 7/7 = 301/35     (1)

similarly, 62/7 = 62/7 x 5/5 = 310/35   (2)

Comparing both (1) and (2),

301/35 < 310/35

:. (301 < 310)

Hence,

Blue Bottle will hold more.

Answer:

24 runners

Step-by-step explanation:

If 1/4 of the runners dropped out, then 1 - 1/4 or 3/4 continued on. 3/4 of 56 or 3/4 *56 is 42 runners left. Then, out of these 42, 3/7 dropped out. This means 1 - 3/7 or 4/7 of the runners remained. This means that 4/7 * 42 or 24 runners finished the race.

Step-by-step explanation:

first pool :

in 4 hours the pool gets 5200 gallons.

that means in 1 hour it gets 5200/4 = 1300 gallons.

so, the filing rate is 1300 gallons / hour.

second pool :

we seen on the graph that

in 3 hours the pool gets 10800 gallons.

that means in 1 hour it gets 10800/3 = 3600 gallons.

so, the filing rate is 3600 gallons / hour.

therefore, the second pool fills at a much faster rate than the first pool (3600 gallons vs. 1300 gallons / hour).

Answer: 50 feet

Step-by-step explanation:

Since it is a rectangle and you in the corner diagonally; you can draw a line diagonally across in the rectangle and you are left with two triangles.

So since its two right-angled triangles

a = 14 feet

b = 48 feet

You need to find c which is the diagonal.

Using the pythagorean theorem which is:

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c^{2} = 14^{2} + 48^{2}[/tex]

Square the a and b then add

[tex]c^{2} = 136 + 2304[/tex]

[tex]c^{2} = 2500[/tex]

Now carry over the square on the c and change it to the square root

[tex]c = \sqrt{2500}[/tex]

when you square root

[tex]c = 50[/tex]

therefore it is 50 feet diagonally across
