Simplify the expression

Answer:

1.) Alex and Jemma decided that they will separate the dozen doughnuts that they bought. Since Jemma loved doughnuts she got 7, and Alex got 5.

2.) 35:49

Divide 35 and 5.

35/5=7

Multiply 7 by 7.

7 x 7=49.

The missing side will be 35:49

Answer:

Step-by-step explanation:

fertilizer b produced a 24% greater yield

mean yield fertilizer a = 20.5

mean yield fertilizer b = 25.5

thus,  

25.5 − 20.5  

20.5

= 0.2439 ≈ 0.24 or 24%

Answer:   D    Where B produced 24% greater yield is the Answer.

Step-by-step explanation:

B produced a 24%  greater yield as 24% of 25 = 4

4 is found when we deduct it from B to find A as smaller.

A= 122.90/6=20.48 mean

B =152.1/6 = 25.35 mean

Step-by-step explanation:

135 gallons of water in the aquarium after 45 minutes of draining.

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that water is draining from an aquarium at a rate of 3 gallons per minute.

The total change in the amount of water in the aquarium after 45 minutes of draining is as:

⇒ 45×3

Apply the multiplication operation in the integers,

⇒ 135 gallons

Hence, 135 gallons of water in the aquarium after 45 minutes of draining.

Answer:

Yes, the ordered pair (-2,-2) is a solution of the system of linear equations.

Step-by-step explanation:

Plug in the x and y value in to the equation and see if the equation is true or not.

Yes, the given ordered pair is the solution of the given system of linear equation.

Systems of equations are used to solve applications when there is more than one unknown and there's enough information to set up equations in those unknowns.

Given is a system of lineae equation,

2x-y = -2

x-2y = 2

Putting x = -2 and y = -2 in 2x-y = -2, we get,

2(-2)-(-2)

-4+2 = -2

LHS = RHS

Again, Putting x = -2 and y = -2 in x-2y = 2, we get,

-2-2(-2) =

= -2+4 = 2

LHS = RHS

Since, the ordered pair satisfying the equations.

Hence, Yes, the given ordered pair is the solution of the given system of linear equation.

Step-by-step explanation:

5-day work week, Matt puts 175 miles on his car. His wife, Sarah, puts 100 more and  28 work days

Answer: 55 cm

Step-by-step explanation:

Hi, to answer this question, first, we have to convert the meters into centimeters.

Since: 1 m = 100 cm

We have to multiply the length of the first frame by 100 to express the length in cm.

9/10 m x 100cm/m = 90 cm

Finally, since she needs 35 centimeters less wood for a second frame, we have to subtract 35 cm to the amount of woof needed for the first frame.

90-35 = 55 centimeters.

Have a nice day.

The letters M,S,V are the original image.

The letters M’, S’, V’ are the displayed image.

You can see that M’, S’,V’ is a smaller image, so it was a reduction.

The length of line MS is 9 units.

The length of M’S’ is 6 units.

The dialation is 6/9 = 2/3

Answer:

(a) reduction

(b) 2/3

Step-by-step explanation:

(a) The original figure is called ΔMSV, while the dilation is called ΔM'S'V'. Because we can see that M'S'V' is clearly much smaller than MSV, we know that the image is a reduction of the original.

(b) We simply need to find the ratio of one side of M'S'V' to one side of MSV. Look at M'S': the length is just 4 - (-2) = 6 (this is because it's a completely horizontal line). The length of MS is 6 - (-3) = 9.

So, the scale factor is: 6 / 9 = 2/3.

Answer:

216

Step-by-step explanation:

I think that it is 216 because if you add 18 and 10 you get 28 then multiply 28 by 12 then you get 336. Then you will find the area of the unshaded part which is 120. Then you will subtract 120 from 336 to get 216.

i believe the answer for X is 25 and Y is 65

Step-by-step explanation:

what i did could be completely wrong but meh anyways if one shape has to add up to 180 degrees you find D which is 90 then add A which is 65 subtract that from 180 and you get your answer for the far left shape. now to find the Y angle subtract 25 from 90 and you get 65 and you already know there is a 90 degree angle so add the subtract that from 180 and then you get 25. also they are the same angles on both shapes just different sizes. i hope i got it right and if i did i hope i helped. =)

Answer:

A. 1/5

B. 60 times

Step-by-step explanation:

The theoretical probability that the pointer(a) is 1/5 and the pointer will land in a section labeled with the letter A after 300 spins (b) is 60

We have given that the Samira is playing a game with the spinner shown.

We have to deterine the theoretical probability that the pointer will land in a section labeled with the letter A on a given​ spin.

This probability is equal to the amount of '1's divided by the total amount of numbers on the spinner.

Thus,The theoretical probability that the spinner is 1/5.

and also the pointer will land in a section labeled with the letter A after 300 spins.

Therefore we get,

Distributive property

Step-by-step explanation:

Distributive property allows you to multiply a(b+c) as ab + ac.

The property which allows her to do this solution is; Distributive property

The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is

A(B + C) = AB + AC

This property is known by distributive law and applies to subtraction also.

We are given that Katrina is asked to simplify the expression Negative 3 a minus 4 b minus 2 (5 a minus 7 b).

She writes:

= -3 a - 4 b - 2 (5 a -7 b)

= - 3 a - 4 b -10 a + 14 b

Answer:

OA = 19.58

Step-by-step explanation:

If we draw the segments OA and OC, we will have an isosceles triangle OAC.

With the property of inscribed angles and central angles that are related to the same arc of the circunference, we have:

mAOC = 2 * mABC

mAOC = 2 * 50 = 100°

As the triangle OAC is isosceles, we have that mOAC = mACO.

Knowing that the sum of internal angles of a triangle is 180°, we have:

mACO + mOAC + 100 = 180

2 * mACO  = 80

mACO = 40°

Now, using the law of sines, we have:

OA / sin(ACO) = AC / sin(AOC)

OA / 0.6428 = 30 / 0.9848

OA = 30.463 * 0.6428 = 19.58
