4.   12c(3a^5b - 1)

Step-by-step explanation:

Greatest common factor of 36 and 12: 12

There are variables a^5b on left term but not on right term, so there is no common factor of a or b.

Greatest common factor of c and c: c

Common factor: 12c

36a^5bc / 12c = 3a^5b

-12c / 12c = -1

Step-by-step explanation:

Each new term is found by multiplying the previous term by 3.  Thus, 3 is the common ratio.  The formula for this geometric series is therefore

a(n) = 23*3^(n - 1).

A bakery takes three types of bread, with the monthly cost being RM 6850
for 2150 loaves of bread. The cost of baking a loof of butterscotch bread
is km 2 a chocolate bread km 3 and a coconut bread Rm 4. The sale prices
of a loaf of butterscotch bread a chocolate bread and a coconut bread
are km 3 , RM 4.50 and km s. so respectively - It the bakery makes a profit
RM 2975 monthly how many loaves of each type of bread will it bake)​

Answers

Answer:

The bakery will bake 600 butterscotch bread, 550 chocolate bread, and 1,000 coconut bread

Step-by-step explanation:

In order to answer the word problem question, we list the parameters as follows;

The number of bread types the bakery takes = 3 types of bread

The monthly cost of the bakery for baking the bread, C = RM 6,850

The number of bread loaves baked = 2,150

The cost of baking a loaf of butterscotch bread = Rm 2

The cost of baking a loaf of chocolate bread = Rm 3

The cost of baking a loaf of coconut bread = Rm 4

The sale price of a butterscotch bread = Rm 3

The sale price of a chocolate bread = Rm 4.50

The sale price of a coconut bread = Rm 5

The amount of monthly profit the bakery makes, P = Rm 2,975

Therefore, the total revenue of the company, R = C + P

∴ R = Rm 6,850 + Rm 2,975 = Rm 9,825

Let 'x', 'y', and 'z', represent the number of loaves of butterscotch, chocolate, and coconut bread the company bakes respectively

Then we get;

x + y + z = 2,150...(1)

2·x + 3·y + 4·z = 6,850...(2)

3·x + 4.5·y + 5·z = 9,825...(3)

Multiplying equation (1) by 2 and subtracting from equation (2) gives;

2·x + 3·y + 4·z - 2×(x + y + z) = 6,850 - 2 × 2,150 = 2,550

2·x - 2·x + 3·y - 2·y + 4·z - 2·z = 2,550

∴ y + 2·z = 2,550...(4)

Adding equation (1) to (2) and subtracting from (3) gives;

3·x - 3·x + 4.5·y - 4·y + 5·z - 5·z = 9,825 - (6,850 + 2,150) = 825

1.5·y = 825

y = 825/1.5 = 550

The number of loaves of chocolate bread baked, y = 550

From equation (4), we get;

550 + 2·z = 2,550

2·z = 2,550 - 550 = 2,000

z = 2,000/2 = 1,000

The number of loaves of coconut bread baked, z = 1,000

∴ From equation (1) x = 2,150 - (550 + 1,000) = 600

The number of loaves of butterscotch bread baked, x = 600.

How far does she walk around the pool every morning? *

141.3
35.33
282.6

Answers

Answer:

Total walk she did around the pool every morning = 141.3

Step-by-step explanation:

Given - Kriti has a circular swimming pool in her house. The radius of the swimming  pool is 22.5 cm. She walks one round every morning before diving in the pool.

To find - How far does she walk around the pool every morning?

Proof -

Given that, the swimming pool is circular in shape.

So,

1 round of circle = Circumference of circle.

As we know that,

Circumference = [tex]2\pi r[/tex]

                         = [tex]2*\pi *22.5[/tex]

                         = 141.3

∴ we get

Total walk she did around the pool every morning = 141.3

Linear equation in slope intercept form

Answers

Answer:

y = 2x + 24

Step-by-step explanation:

Slope-intercept form equation => y = mx + b

m = slope = change in y / change in x

b = y-intercept

✔️using two pairs of values form the table, (-6, 12) and (-5, 14):

Slope (m) = (14 - 12)/(-5 -(-6))

m = 2/1

m = 2

✔️To find b, substitute (x, y) = (-6, 12) and m = 2 into y = mx + b.

12 = 2(-6) + b

12 = -12 + b

12 + 12 = b

24 = b

b = 24

✔️To write the equation, substitute m = 2 and b = 24 into y = mx + b:

y = 2x + 24

A triangle has one angle of 120 degrees what must be true about the other two angles A- the sum of the two angles must be equal to 120 degrees. B- the two angles must be the same measure C- the sum of two angles must be 60 degrees

Answers

Answer:

C

Step-by-step explanation:

Since all triangles' angles have a sum of 180 degrees, it can't be A, because that would make it 240 degrees. That leaves us with B and C. While B could be true, we don't know it for sure. Therefore, C is the correct answer because adding them should equal 60 degrees, which, adding them to the first angle (which was 120 degrees), would 180 degrees.

The area of the composite shape is:

122.50 [tex]cm^{2}[/tex]

Step-by-step explanation:

To find the area of composite shapes you can pull apart this in known shapes, in this case, a rectangle and a triangle. Taking into account this, we can find the rectangle area firstly:

Rectangle area = base * height

The base of the rectangle is the measure from down (14 cm) and the height is the measure in the left side (7 cm), with these values we can replace the formula:

Rectangle area = base * heightRectangle area = 14 cm * 7 cmRectangle area = 98 [tex]cm^{2}[/tex]

Now, to calculate the area of the remaining triangle, we must use the next formula:

Triangle area = [tex]\frac{base*height}{2}[/tex]

Where the base would be equal to the left side of the shape (7 cm) and the height is the difference between the measurement in the top side and the measurement in the bottom side:

Height of the triangle = top side - bottom sideHeight of the triangle = 21 cm - 14 cmHeight of the triangle = 7 cm

We can replace in the formula:

Triangle area = [tex]\frac{7 cm * 7cm}{2}[/tex]Triangle area =[tex]\frac{49cm^{2} }{2}[/tex]Triangle area = 24.5 [tex]cm^{2}[/tex]

By last, we must add the two values of the areas obtained:

Area of the composite shape = rectangle area + triangle area.Area of the composite shape = 98 [tex]cm^{2}[/tex] + 24.5 [tex]cm^{2}[/tex]Area of the composite shape = 122.5 [tex]cm^{2}[/tex]

A sculptor plans to ship the pyramid shown in one of three boxes. The interior of the pyramid holds 4,500 cm3 of water. The base is an isosceles trapezoid. Into which boxes will the pyramid fit? Drag “yes” or “no” to each box height.

Answers

Answer:

28 cm and 32 cm

Step-by-step explanation:

Volume of the pyramid:

V = 1/3Bh

Find base area:

B = 1/2(20 + 30)*20 = 500 cm²

Substitute value of the volume and find the height of the pyramid:

4500 = 1/3*500*hh = 4500*3/500h = 27 cm

The boxes with h > 27 can fit the pyramid:

28 cm and 32 cm

Area of base

1/2(30+20)(20)10(50)500cm²

Volume=1/3Area×Height

Height

4500(3)(500)27cm

So answers are

Answer:

(10/3, 2/3)

Step-by-step explanation:

You may find it easier to write these two equations x+y=4 2x-y=6 in a column:

x+y=4

2x-y=6

Adding these together will eliminate y:

3x = 10.  Then x = 10/3.

Substituting 10/3 for x in the first equation results in:

10/3 + y = 4

Clear fractions by multiplying all three terms by 3:

10 + 3y = 12

Then 3y = 2, and y = 2/3.

The solution is (10/3, 2/3)

Two frogs had a jumping contest. The heights they jumped are shown below.
Frog one jumped 70cm
Frog two jumped 850mm
What is the difference between the distances, in millimeters?

Answers

Answer: 150mm

Step-by-step explanation:

We should note that 10 millimeter = 1 centimeter. Therefore, 70cm to mm will be:

= 70 × 10 = 700mm

Frog one jumped 70cm = 700mm

Frog two jumped 850mm

The difference between the distance will be:.

= 850mm - 700mm

= 150mm
