Answer:

1.63 cm

Step-by-step explanation:

Volume of water in Tank A

Volume of Tank B

Finding Height

Answer:

1.63 cm (nearest hundredth)

Step-by-step explanation:

Formulae

Volume of a cuboid = base width × base length × height

Area of a rectangle = width × length

Tank A

Given:

⇒ Volume of Tank A = 7 × 7 × 7 = 343 cm³

Tank B

⇒ Base area of Tank B = 14 × 15 = 210 cm²

Solution

Height = volume of Tank A ÷ base area of Tank B

           = 343 ÷ 210

           = 49/30 cm

           = 1.63 cm (nearest hundredth)

Answer:

[A} 5x = 19

Step-by-step explanation:

Let's solve to see what the first step in solving the following equations:

5x - 4 = 15

Add 4 to both sides

5x - 4 + 4 = 15 + 4

5x = 19 {First step after solving}

Divide both sides by the same factor

5x/5 = 19/x

x = 3.8

Thus, the answer is [A] 5x = 19

Kavinsky

Answer:

[A] 5x = 19

Step-by-step explanation:

Solving to see first step:

5x - 4 = 15

     +4    +4          {15 + 4 = 19}

-------------------------

5x = 19    

Divide both sides by 5

5x/5 = 19/5

x = 19/5

x = 3.8

As you can see 5x = 19 is the first step result after solving.

Answer:

[tex]y=\frac{3}{2}x-8[/tex]

Step-by-step explanation:

We can use the definition of slope-intercept form to answer this:

[tex]y=mx+b[/tex]

Where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.

So all we do is stick in the numbers and we get:

[tex]y=\frac{3}{2}x - 8[/tex]

Answer:

y=2x-5

Step-by-step explanation:

Hi there!

We are given that a line has a slope of 2, and passes through the point (4,3)

We want to use point-slope form to find this equation of the line, yet we want to write this in slope-intercept form

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point

As we are already given the slope and a point, we can substitute these values into the formula to find the line.

First, substitute 2 as m in the equation:

[tex]y-y_1=2(x-x_1)[/tex]

Now substitute 4 as [tex]x_1[/tex] and 3 as [tex]y_1[/tex]

[tex]y-3=2(x-4)[/tex]

This is the equation of the line in point-slope form.

Now we need to write it in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

We can actually get to slope-intercept form from point-slope form.

First, distribute 2 to both x and -4 on the right side

y-3=2x-8

Now add 3 to both sides

y=2x-5

Hope this helps!

Answer:

0.53

Step-by-step explanation:

A fraction bar can also mean division. So 8/15 the fraction also means 8÷15.

8÷15 = 0.5333333...

Rounding to the nearest hundredth means there should be only two numbers to the right of the decimal point.

8/15 ~= 0.53

Step-by-step explanation:

Properties of a parallelogram

Use the properties to find the required parameters

1) Find m∠YXV

2) Find m∠Y

3) Find x

Answer:

m∠YXV = 56°

m∠Y = 84°

x = 3

Step-by-step explanation:

Sum of interior angles of a triangle = 180°

⇒ m∠W + m∠WVX + m∠VXW = 180°

⇒ 84° + m∠WVX + 40° = 180°

⇒ m∠WVX = 56°

As VW ║ YX  and  YV ║ XW  then  m∠WVX = m∠YXV

So m∠YXV = 56°

In a parallelogram, opposite angles are congruent

⇒ m∠Y = m∠W

⇒ m∠Y = 84°

In a parallelogram, opposite sides lengths are congruent

⇒ VW = YX

⇒ 2x = 6

⇒ x = 6 ÷ 2

⇒ x = 3

Answer:

A)Let's let M = the number of Multiple choice problems and

N = the number of essay questions.

B)Also, since there are 36 questions altogether, we can say that

M + N = 36

So, therefore

M = 36 - N

Hope this helped I couldn’t get C very confusing.

Answer:

Below in bold.

Step-by-step explanation:

y = x^2-8x+6

y = (x - 4)^2 - 16 + 6

y = (x - 4)^2 - 10

So the vertex is at (4, -10)

The coefficient of x^2 of this function is 1 ( positive) so there will be  a minimum value.

Minimum value = -10.

x-intercepts:

(x - 4)^2 - 10 = 0

(x - 4)^2   =   10

x -  4 =  +/- √10

x =  4 +/- √10

- therefore there are 2 x-intercepts.

The expense amount is more than the savings amount. No, it's short $207 then the correct option is A.

Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, and summarise the data.

From the table, we have

The amount of the savings will be

Saving amount = $ 20

Then the amount of the expense will be

Expense amount = 150 + 75 + 2 = 227

Then the budgeted amount covers the actual amount for expenses, savings, and emergencies will be

→ savings amount - expense amount

→ 20 - 227

→ $ 207

Thus, the expense amount is more than the savings amount. No, it's short $207.
