Answer:

Step-by-step explanation:

we know that

surface area of the prism=2*area of the base+perimeter of the base*height

step 1

find the area of the base

area of the base=length* width

length=5 cm

width=4 cm

area of the base=5*4-----> 20 cm²

step 2

find the perimeter of the base

perimeter=2*[length+width]-----> 2*[5+4]----> 18 cm

step 3

height=7 cm

step 4

find the surface area

surface area of the prism=2*area of the base+perimeter of the base*height

surface area of the prism=2*20+18*7----> 166 cm²

Answer:

-3.35 is your answer. B.

Answer:

With the way the problem is facing, the correct option is B.

[tex]6.2[/tex] ≈ [tex]6[/tex]

[tex]9.55[/tex] ≈ [tex]10[/tex]

[tex]6 - 10 = -4[/tex] because of the order. Otherwise, it would be positive 4

[tex]6.2 - 9.55 = -3.35[/tex]

________________________________________________________

And the problem is solved. -3.35 is your answer. Remember, in the future, always go by the order of operations. If you do not follow the order of operations, that could be a disaster!

Lucie must buy 5 more than half of Suzie's purchase to have 10 more cards than two thirds of the girls’ total

Represent Lucie's card with L and Suzie's card with S.

So, the total number of cards is:

Total = L + S

Lucie's number of cards can be represented as:

L = 10 + 1/3(L + S)

Multiply through by 3

3L = 30 + L + S

Subtract L from both sides

2L = 30 + S

Divide by 2

L = 15 + 0.5S

Let x represents the additional number of cards.

So, we have:

x + L = 10 + 2/3(L +S)

Substitute L = 15 + 0.5S

x + 15 + 0.5S = 10 + 2/3(15 + 0.5S + S)

Evaluate the sum

x + 15 + 0.5S = 10 + 2/3(15 + 1.5S)

Expand

x + 15 + 0.5S = 10 + 10 + S

Evaluate the sum

x + 15 + 0.5S = 20 + S

Subtract 0.5S from both sides

x + 15 = 20 + 0.5S

Subtract 15 from both sides

x = 5 + 0.5S

The above means that Lucie must buy 5 more than half of Suzie's purchase to have 10 more cards than two thirds of the girls’ total

Step-by-step explanation:

Answer:

1. A. 1

2. D. [tex]17^9[/tex]

Step-by-step explanation:

Properties used:

1. First, let's deal with the numerator.

[tex](17^3)^6[/tex] can be turned into [tex]17^1^8[/tex] by using the Power of a Power Property.

And then use the Product Property, [tex](17^1^8)(17^-^1^0) = 17^8[/tex]

So now, our fraction is this: [tex]\frac{17^8}{17^8}[/tex]

All number over itself in a fraction is equal to 1. But you can also do this the mathmatic way using the Quotient Property: [tex]\frac{a^m}{a^n} = a^m^-^n[/tex] or [tex]\frac{1}{a^(^n^-^m^)}[/tex]. Which then you plug the numbers in: [tex]\frac{17^8}{17^8} = 17^8^-^8 = 17^0[/tex]. And since we know that in Zero Exponent Property: [tex]a^0 = 1[/tex], we can see that [tex]17^0 = 1[/tex]. So either way, we get 1.

So the answer is 1, which is A

2. Power of a Power Property: [tex](a^m)^n = a^m^n[/tex]

So plug the numbers in the property: [tex](17^{6}) ^3[/tex]= [tex]17^1^8[/tex]

Product Property: [tex](a^m)(a^n) = a^m^+^n[/tex]

We plug the equation in with [tex](17^{6}) ^3[/tex] turned into [tex]17^1^8[/tex] ---

[tex](17^1^8)(17^-^9) = 17^1^8^-^9 = 17^9[/tex]

So the answer is [tex]17^9[/tex], which is D

Step-by-step explanation:

reflection across axis would make the points be (4,-4)

translating five units left would make it (-1, -4)

Answer:

Answer Choice C is the closest. (**There should be a second transformation in order to get it correct look at my explanation!!**)

Step-by-step explanation:

From our information, I think C is correct.

**There is something missing for the translation**

The reason why C is the closest is that if we reflect across the x-axis, our coordinate for (4,4) would be (4,-4). Then if we went 5 units to the left, then we would get to (-1,-4) in which we have to go up 2.

Answer choices A, B, and D aren't close to (-1,-2).

The closest you'll get on this is C because as I mentioned in my explanation your stopping point would be (-1,-4) in which you need a second transformation that is 2 units up to get exactly (-1, -2).

Answer:

part a. she has an 8 out of the 15 counters chance at getting red. part b. she has a chance of 262 times out of the 300 to get red

Step-by-step explanation:

i hope this helps and i'm sorry if it's wrong have a lovely day

The probability that it will be red is 8/15.

The number of times out of 300 Taylor will pick a red counter is 160.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have,

Taylor has a bag containing 15 counters.

First, the probability that it will be red

= 8/15

Now, if she repeats 300 times then

= 8/15 x 300

= 8 x 20

= 160

Answer:

Yes

Step-by-step explanation:

10.25 oz x 7 days = 71.75 oz

7.5 oz x 7 days = 52.5 oz

71.75 oz + 52.5 oz = 124.25 oz

124.25 oz < 126 oz

Answer:

yes

Step-by-step explanation:

10.25x7 =71.75

7.5x7=52.5

52.5+71.75=124.25

Gallons and quarts

1 gallon = 4 quarts.

So, we have:

5 gallons = 20 quarts i.e. 5 * 4

Hence,

5 gallons >  18 quarts

Pints and cups to fl oz

1 cup = 0.5 pints.

So, we have:

1 pint 4 cups = 1 pint + 2 pints

1 pint 4 cups = 3 pints

1 pint = 16 fl oz.

So, we have:

1 pint 4 cups = 16 * 3 fl oz

1 pint 4 cups = 48 fl oz

Hence,

1 pint 4 cups >  32 fl oz

Pints and cup

1 cup = 0.5 pints.

So, we have:

8 cups = 4 pints

Hence,

3 pints <  8 cups

Quarts and gallon

1 gallon = 4 quarts.

So, we have:

4 gallons = 16 quarts

Hence,

13 quarts < 4 gallons

Answer:

6

Step-by-step explanation:

Using the Triangle Inequality Theorem, we can derive the range in which the third side, x. If you are having trouble with the theorem, it is that the sum of any two sides must be larger than the other side.

4 + 9 > x => x < 13

x + 4 > 9 => x > 5

x + 9 > 4 => x > -5

Combining all three equations gives us 5 < x < 13

Since the number is a whole number, the smallest whole number that satisfies the range is 6. The answer is 6.
