I mean we don’t have to use the net becuase there is a shape right there already so the answer is 280 m for SA

Step-by-step explanation:

So find 5*6 first aAnd you’d get 30

30*2 becuase there are 2 sides, 60

10*6 is 60

60*2 is 120

5*10 is 50

50*2 is 100

now add them all up

you’d get 280 inches :)

Mary bought these art supplies: 4 paint brushes at $1.29 each, 6 dowel rods at $1.49 each, a jar of paste at $1.25, and 2 canvases at $6.00 each. How much change did she get from $40?

A. $8.25

B. $9.35

C. $10.45

D. $12.65
I'll give brainliest!

Answers

Answer: The answer is D.

Step-by-step explanation:

Multiply the art supplies with their assigned prices, then combine like terms.

The answer is D

Explanation:

1.29 times 4 is 5.16 1.49 times 6 is 8.94 and 6.00 times 2 is 12.00. Add those together including 1.25 and you are going to get 27.35 then you subtract that from 40.00

Polygon MNP shown on the coordinate planeA dilation centered about the origin will be performed on the polygon with vertices M(- 18, 12) forall(8,10),8(-6,8) and Q(- 8, - 8)

Answers

Answer:

N'(4, 5)

Step-by-step explanation:

The correct question is attached.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.

Dilation is a transformation that changes the size of a figure (i.e. it increases or reduces the size).

If a point A(x, y) is dilated by a factor k, the new point is at A'(kx, ky).

The location of the polygon vertex is at M(-16, 12), N(8, 10), P(-6, 8) and Q(-8, -8).

After dilation, the new location of M is at M'(-8, 6)

M(-16, 12) ⇒ M'(-8, 6)

M(-16, 12) ⇒ M'[1/2(-16), 1/2(12)]

Hence the dilation factor is 1/2. This means that the new vertex is at:

N'(4, 5), P'(-3, 4) and Q'(-4, -4).

Alexus is modeling the growth of bacteria for an experiment in science. She assumes that there are B bacteria in a Petri dish at 12:00 noon. In reality, each bacterium in the Petri dish subdivides into two new bacteria approximately every 20 minutes. However, for the purposes of the model, Alexus assumes that each bacterium subdivides into two new bacteria exactly every 20 minutes.

2a. Create a table that shows the total number of bacteria in the Petri dish at 1/3 hour intervals for 2 hours starting with time 0 to represent 12:00 noon.

2b. Write an equation that describes the relationship between total number of bacteria T and time h in hours, assuming there are B bacteria in the Petri dish at h=0.

2c.If Alexus starts with 100 bacteria in the Petri dish, draw a graph that displays the total number of bacteria with respect to time from 12:00 noon (h=0) to 4:00 p.m. (h=4). Label points on your graph at time h=0,1,2,3,4.

2d. For her experiment, Alexus plans to add an anti-bacterial chemical to the Petri dish at 4:00 p.m. that is supposed to kill 99.9% of the bacteria instantaneously. If she started with 100 bacteria at 12:00 noon, how many live bacteria might Alexus expect to find in the Petri dish right after she adds the anti-bacterial chemical?

Find the value of x and y

Answers

Answer:

x=45 degrees

y=45 degrees

Step-by-step explanation:

Answer: y = 50; x = 34

ABCD is a quadrilateral inscribed in the circle

=> ∠ABD = ∠ACD

⇔ x = 34°

and ∠ADB = ∠ACB

we also have:

∠DCE + ∠ DCB = 180°

⇔ 96° + x + ∠ACB = 180°

⇔ ∠ACB = 180 - 96 - x = 180 - 96 - 34 = 50

because ∠ADB = ∠ACB => y = 50°

When you’re multiplying or dividing same sign numbers, what will your product or quotient be?

Answers

When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative.

The answer will be the opposite of the sign so for example -5*-5= 25

Answers

4 cubed = 4^3
4 * 4 * 4 = 16 * 4 = 64
Therefore 4 cubed is 64

Answer:

Step-by-step explanation:

4 cubed is 64 because 4 cubed can be written as an exponentiation, where the base is 4 and the exponent is 3, like this: 43. For future reference, note that cubed means that the exponent is 3 regardless of what the base is. When the exponent is 3 (aka cubed) and the base is 4 you simply multiply 4 by 4 by 4 to get the answer 64

Answers

-4 = 2b

2b = -4

b = -4/2

b = -2

There is one solution and it is b = -2

A quick way to tell we have one solution is to note that both sides are a linear expression, and that the slopes of each linear expression are different values. If you had two lines with the same slope, then you'd have either parallel lines or coinciding lines (leading to no solutions and infinitely many solutions respectively). When you have two lines with two different slopes, then they are guaranteed to intersect only once. That intersection point is the solution.

Answer:

The answer is one solution

Step-by-step explanation:
