Answer:

Linear

Step-by-step explanation:

The equation is in the form y = mix + b, which means it is linear.

56+72+x =180 ( therefore sum of angle in a triangle)

128+x=180

x=180-128

x=52

Answer:

THE MISSING ANGLE = 52°

Step-by-step explanation:

Sum of all angles = 18°0

Let the missing angle be x°

56° + 72° + x° = 180°

x° = 180° - 72° - 56°

x° = 52°

Dale would need to buy more than 200 cards for Company B to be cheaper.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Company A charges a flat fee of $0.15 per card.

Company B charges $0.10 per card plus an additional $10.00 for delivery

Let x = number of cards

Company A charges = $0.15x

Company B charges = $10.00 + $0.10x

For company B to be the cheaper option      ( B < A )

     $10.00 + $0.10x  <  $0.15x

     $10.00  <  $0.05x      

subtracting positive from both sides to retains the sense of the inequality and x is positive

       200 < x      

       x > 200    

So, Dale would need to buy more than 200 cards for Company B to be cheaper.

The expression  that will find the amount of interest tran will be charged after the first month is: (0.01) (300 dollars).

First step

Monthly interest rate = (Annual percentage rate ÷ Number of months in a year)

Monthly interest rate= 0.12 ÷ 12

Monthly interest rate= 0.01

Second step

Amount left = Amount charged - Amount paid

Amount left = $450 - $150

Amount left = $300

Third step

Amount of interest=Monthly rate ×Amount left

Amount of interest=(0.01) (300 dollars)

Amount of interest=$3

Therefore the expression  that will find the amount of interest tran will be charged after the first month is: (0.01) (300 dollars).

Answer:

Step-by-step explanation:

Isolate the variable of y from one side of the equation.

-14=5(3y-10)-5y

First, switch sides.

[tex]\sf{5\left(3y-10\right)-5y=-15}[/tex]

Use the distributive property.

DISTRIBUTIVE PROPERTY:

A(B-C)=AB-AC

5(3y-10)

Multiply by expand.

5*3y=15y

5*10=50

15y-50-5y

15y-5=10y

= 10y-50

10y-50=-15

Add by 50 from both sides.

10y-50+50=-15+50

Solve.

10y=35

Then, you divide by 10 from both sides.

10y/10=35/10

Solve.

Divide the numbers from left to right.

35/10=7/2

y=7/2

Divide is another option.

7/2=3.5

[tex]\Longrightarrow: \boxed{\sf{y=\dfrac{7}{2}}}[/tex]

Answer:

A. 1/220   B. 1/22   C. 3/11

Step-by-step explanation:

This question uses combinations -- counting the number of ways a selection can be made from a set of objects (without arranging them after the selection is done).

Notations for combinations:

The number of ways to select  r  things from a set of  n  things is

[tex]C(n,r)=\frac{n!}{r!(n-r)!}[/tex]  where the exclamation points mean factorial.

[tex]n!=1\cdot2\cdot3\ldots\cdot n[/tex]  and 0! is defined to be 1.

There are two other commonly used symbols for this:

[tex]_nC_r[/tex]  and  [tex]n \choose x[/tex].

In all three parts, the number of ways to choose 3 balls from a set of 12 is

[tex]C(12,3) = \frac{12!}{3!(12-3)!}=\frac{12\cdot 11 \cdot 10 \cdot 9\cdot 8\cdot 7\cdot 6\cdot 5\cdot4\cdot3\cdot2\cdot1}{(3\cdot2\cdot1)(9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot2\cdot1)}[/tex]

Notice that 9 factors in the denominator cancel 9 factors in the numerator, leaving

[tex]C(12,3) = \frac{12!}{3!(12-3)!}=\frac{12\cdot 11 \cdot 10}{3\cdot2\cdot1}=220[/tex]

A. The number of ways to choose 3 red balls from the 3 red balls is C(3, 3) = 1, so the probability is 1 / 220.

B)  The number of ways to choose 3 green balls from the set of 5 green balls is [tex]C(5,3)=\frac{5!}{3!(5-3)!}=\frac{5!}{3!2!}=\frac{5\cdot 4}{2}=10[/tex]  out of 220, so the probability is 10/220 = 1/22.

C)  The number of ways to choose 1 red is C(3, 1) = 3.  Choose 1 green in C(5, 1) = 5 ways.  Choose 1 white in C(4, 1) = 4 ways.

The probability is  [tex]\frac{3\cdot 5 \cdot 4}{220}=\frac{60}{220}=\frac{3}{11}[/tex]

Answer:

a) 1/220

b) 1/22

Answer:

The length of each side of square is 5ft.

Step-by-step explanation:

A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.

The area of the triangle is 7.5ft squared.Area of combined figure - area of triangle = area of square.

32.5 ft squared - 7.5 ft squared = 25 ft squared.

So, area of square = 25 ft squared.

Now, by putting the formula for getting the length of each side:

Let the side = a.

Area of square = 25 ft squared

Area of square = a²

Using square root both sides we get:

So, the side = 5 ft.

Therefore, the length of each side of square is 5ft.

Find the required water volume using the volume of prism formula

Find the time required

Answer:

40 hours

Step-by-step explanation:

The swimming pool can be modeled as a rectangular prism.

Volume of a rectangular prism

where:

First, calculate the volume of water needed:

Given:

Substitute the given values into the formula and solve for V:

[tex]\implies V=10 \cdot 5 \cdot 2=100\:\: \sf m^3[/tex]

If the water flows as a rate of 2.5 m³/h, divide the volume by the rate to calculate how long it will take to fill the pool:

[tex]\implies \sf Time=\dfrac{Volume}{rate}[/tex]

[tex]\implies \sf Time=\dfrac{100}{2.5}[/tex]
