Answer:

Step-by-step explanation:

1). There is 5 hours between 8:15 A.M. and 3:15 P.M.

7 × 60 - 10 = 410 minutes

2). 6 hours and 50 minutes

3). Right angle (90°)

4). Obtuse angle (120°)

Answer:

[tex]x^2 + 15x - 60 = 0[/tex]

The actual dimension is 18.28 by 3.28

Step-by-step explanation:

Given

Dimension:

[tex](x + 15)\ by\ x[/tex]

[tex]Area = 60in^2[/tex]

Required

Determine the quadratic equation and get the possible values of x

Solving (a): Quadratic Equation.

The cardboard is rectangular in shape.

Hence, Area is calculated as thus:

[tex]Area = Length * Width[/tex]

[tex]60= (x + 15) * x[/tex]

Open Bracket

[tex]60= x^2 + 15x[/tex]

Subtract 60 from both sides

[tex]x^2 + 15x - 60 = 0[/tex]

Hence, the above represents the quadratic equation

Solving (b): The actual dimension

First, we need to solve for x

This can be solved using quadratic formula:

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 1[/tex]

[tex]b = 15[/tex]

[tex]c = -60[/tex]

So:

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]x = \frac{-15 \± \sqrt{15^2 - 4*1*-60}}{2*1}[/tex]

[tex]x = \frac{-15 \± \sqrt{225 + 240}}{2}[/tex]

[tex]x = \frac{-15 \± \sqrt{465}}{2}[/tex]

[tex]x = \frac{-15 \± \21.56}{2}[/tex]

Split:

[tex]x = \frac{-15 + 21.56}{2}[/tex] or [tex]x = \frac{-15 - 21.56}{2}[/tex]

[tex]x = \frac{6.56}{2}[/tex] or [tex]x = \frac{-36.36}{2}[/tex]

[tex]x = 3.28[/tex] or [tex]x = -18.18[/tex]

But length can't be negative;

So:

[tex]x = 3.28[/tex]

The actual dimensions: [tex](x + 15)\ by\ x[/tex] is

[tex]Length =3.28 +15[/tex]

[tex]Length =18.28[/tex]

[tex]Width = x[/tex]

[tex]Width =3.28[/tex]

The actual dimension is 18.28 by 3.28

Answer:

The answer is 9

Step-by-step explanation:

for the equation:

move the -6x

x^2 + c - 6x

To find c :

c = (b/2)^2

this means you have to divide the coefficient of x by 2 then square the result

If you dont understand I put a picture of all the steps

Answer:

13.5

Step-by-step explanation:

just subtract everything aan keep the 13/5 and use tat

Answer:

y = 11.2

Step-by-step explanation:

Given:

The Side-Splitter Theorem states that:

JKP is any triangle

KL is drawn parallel to MN, then JK/KM = JL/LN

JK/KM = JL/LN = KL/MN

9/13.5 = (37.5 - x)/x = 7.5/y

9/13.5 = 7.5/y

y = 11.249

9/13.5 = (37.5 - x)/x

x = 22.5

Answer:

Answer:

Any number in form of x.y = x (1) + 1/10 (y)

where x = 5 & y > 3 , or x > 5

Step-by-step explanation:

Expanded form of 5.3 = 5 (1) + 3 (1/10)

Some decimals written in expanded form that are greater than 5.3    :

5 (1) + 4 (1/10) = 5.4

6 (1) + 2 (1/10) = 6.2  

Answer:

Step-by-step explanation:

propportinal

means that the points are inproportion

ratios

1:3=2:6=3:7

1/3=2/6=3/7

1/3=1/3=3/7

false

therefor it is not poropoortional

another way is to graph the points and see if a straight line can go though all of them

it can go thoruhg the first 3 but not eh 4th pont (3,7)

not proportional

Answer:

4 and -4

Step-by-step explanation:

Because 4 to the left of 0 is negative and 4 to the right is positive

Answer:

The two numbers are: -4 and +4 (or just 4)

I HOPE THIS HELPS

Answer:

B

Step-by-step explanation:

this is the correct awnser because the thingy is y-y¹=slope(x-x¹) so for y¹ it would be 2 and that gives away the awnser. because all of the other ones have different numbers if the minus sign is an addition sign it mean that the y¹ is negative which it isnt.

how you would find the y¹ is you look on the y-axis and see where the line goes through perfectly which is the positive 2

Hope this helps!

Answer:

7/15

Step-by-step explanation:

find a common demonator for example 15

you would do 4x3 for 12 and 5x3 for 15 so your first fraction would be 12/15

for the second fraction you will do 1x5 and 3x5 so your fraction would be 5/15

then you just subtract.

Answer:

7/15

Step-by-step explanation:

4/5 - 1/3. Change the denominators to 15, do they same to the numerators which is multiply by 5. You then have 12 minus 5 = 7. So 7/15.

Answer:

2*{2*i*√(10) - 20}

Step-by-step explanation:

i will interpret your expression as being

sqrt{-40}  − 40.  The first term factors to

sqrt{-4*10)

and the second stays as is.  

Then we have

sqrt(-4*10) - 40, or

i*2*sqrt(10) - 40, or

2*{2*i*sqrt(10) - 20}, or

2*{2*i*√(10) - 20}

Answer:

-2 < y ≤ 10

Step-by-step explanation:

The graph's lowest point is at y = -2, and the graph's highest point is at y = 10, so we know it would start off with -2 and end with 10. The dot at the lowest point is not shaded in, indicating that the graph does not include -2. So, we would represent this exclusion in our inequality with a less than (<) sign. As for the highest point at y = 10, it is shaded in, indicating that the graph does include 10. We would show this in our inequality with a less than or equal to sign (≤)

Answer:1/3

Step-by-step explanation:

The formula for finding slope is (y2-y1)/(x2-x1)

(-1--2)/(5-2)

1/3

Answer:

The equation that represents the amount that Aziz earns for the number of lawn he mows is e = 15.875 × n

Step-by-step explanation:

From the graph, we have;

For the point where n = 4, we have e ≈ 63.5

Therefore, we have;

The slope = Δn/Δe = 63.5/(4) = 15.875

The coordinates of the points plotted on the graph are as follows;

n = 0, e = 0, therefore, the y-intercept is 0, and y = slope × x

n = 1, e = 1 × 0.79375 = 15.875

n = 2, e = 2 × 15.875 = 31.75

n = 3, e = 2 × 15.875 = 47.625

n = 4, e = 4 × 15.875 = 63.5

We have, e = 15.875 × n

Where, n represents the number of lawns Aziz mows, and n represents the amount of earnings Aziz makes in dollars

Therefore, the equation that represents the amount that Aziz earns for the number of lawn he mows is e = 15.875 × n

Answer:

ef + eg

Step-by-step explanation:

Distributive Property: a(b +c) = (a*b) + (a*c)

e(f +g) = e*f + e*g

Answer:

The y intercept is where the number of minutes producing fruit cans is 0 and the value of the number of minutes for producing vegetable cans is on the y-axis.

Step-by-step explanation:

A y-intercept is where the x value is 0 and the y-value is on the y-axis. So, the answer consists of making the x value 0.

Answer:

Sample Answer: The x-intercept, at the point (16, 0) indicates the choice to produce fruit for 16 minutes. In 16 minutes, producing 24 cans of fruit a minute, all 384 cans for the order will be completed. The zero for the y-value represents that no time is spent producing cans of vegetables.

Step-by-step explanation:

Answer:

40 gallons

Step-by-step explanation:

Let the number of gallons that would completely fill the bathtub be represented by N.

Since 12 gallons of water gives 30% of the number of gallons to fill the bathtub, then;

30% of N = 12

[tex]\frac{30}{100}[/tex] x N = 12

30N = 12 x 100

30N = 1200

divide both sides by 30,

N = [tex]\frac{1200}{30}[/tex]

   = 40

The number of gallons that would completely fill the bathtub is 40 gallons.
