4 < 8 (true)

9 (2) + 5 > 23

23 > 23 (not a true statement)

4 (3) - 4 < 8

8 < 8 (not a true statement)

9 (3) + 5 > 23

32 > 23 (true)

Answer:

n = 9

Step-by-step explanation:

Here we have the table:

X     Y

4     3

6    5

7     6

10   n

First, we want to find the rule.

in the first pair we have:

x = 4

y = 3

We can see that the y-value is one smaller than the x-value

y = 3 = 4 - 1 = x - 1

For the second pair we have:

x = 6, y = 5

We again can see that the y-value is one smaller than the x-value

y = 5 = 6 - 1 = x - 1

For the third pair we have:

x = 7, y = 6

Again, can see that the y-value is one smaller than the x-value.

y = 6 = 7 - 1 = x - 1

We can conclude that the rule is:

y = x - 1

For the last pair, we have:

x = 10, y = n

Then:

n = 10 - 1 = 9

n = 9

Then the table is:

X     Y

4     3

6    5

7     6

10   9

Answer:

3.00 years

Step-by-step explanation:

Cindy Lou deposited $85 in the bank earning 4.5% interest annually. About how many years will it take her to earn $11.48 in interest?

Your answer

Given data

Principal= $85

Rate= 4.5%

Intterest=  $11.48

The simple interest formula is

SI= PRT/100

11.48= 85*4.5*T/100

cross multiply

11.48*100= 85*4.5*T

1148=382.5T

divide both sides by 382.5

T= 1148/382.5

T= 3.00 years

Hence the time is 3 years

Answer:

n = 30m + 1,200

Answer:

49.5 ounces the flower

3 pounds, 1.5 ounces

Step-by-step explanation:

Given that :

24 cupcakes 9 ounces of flower

Number of ounces of flower required for 132 cupcakes will be x

Using cross multiplication method :

24 cupcakes = 9 ounces

132 cupcakes = x ounces

Cross multiply :

24 * x = 132 * 9

24x = 1188

divide both sides by 24 to isolate x

x = 49.5

Hence, 49.5 ounces the flower is required for 132 cupcakes

To express in pounds :

1 pound = 16 ounces

49.5 ounces = 3 pounds 1.5 ounces

A. the $5 off coupon

Step-by-step explanation:

10% off would only be 2.99 off the bill making it 26.91 but the $5 would take off more

The coupon I would use to save the most amount of money on the total bill is my friend's coupon worth $5.

Coupons reduce the price of an item. An item becomes cheaper after a coupon has been used. In order to determine the better coupon, calculate the price after each coupon has been used.

Coupon 1 : 10% x 29.9 = $3

Coupon 2 : 29.90 - $5 = $24.90

Answer:

Each customer bought 45 boxes which is equivalent to mangoes 3240 in total.

Step-by-step explanation:

1. Subtract 3 boxes from the total of 138 imported boxes. ( 3 boxes are the 72 mangoes for his friends )

2. Divide 135 by 3 ( The amount of customers ) = 45 boxes per customer.

3. 45 x 24 ( The amount of mangoes in each box ) = 1080

4. 45 boxes/1080 mangoes per customer.

To recheck:

1080 x 3 ( The amount of customers again ) = 3240.

135 x 24 ( The amount of mangoes per box ) = 3240.

Answer:

480

Step-by-step explanation:

I did the test and this is what it said in the review.

The new volume of the prism is 480 m³, option B is correct

A three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The total surface area of the prism is given by:

2lw + 2lh + 2wh = 360

Dividing both sides by 2, we get:

lw + lh + wh = 180

The volume of the prism is given by:

lwh = 60

Multiplying both sides by 8, we get:

8lwh = 480

Substituting 2l, 2w, and 2h for l, w, and h, respectively, we get:

(2l)(2w)(2h) = 8lwh

(2l)(2w)(2h) = 480

Simplifying, we get:

(2l)(2w)(2h) = 8lwh

8lwh = 480

Therefore, the new volume of the prism is 480 m³, option B is correct

Answer:

Step-by-step explanation:

P(t) = P0 * (1 + r)^t

P(t) = 100 * (1 + 90/100)^t#

P(t) = 100 * (1 + 0.9)^t

Therefore, the number of bacteria in 5 years :

P(5) = 100 * (1 + 0.9)^5

P(5) = 100 * (1.9)^5

P(5) = 100 * 24.76099

P(5) = 2476.099

P(5) = 2476 bacteria

Answer:

60.26yd³

Step-by-step explanation:

Since we are not given the diagram, let us assume that;

Length of the base = 5.4yd

Height of the pyramid = 6.2yd

volume of the square pyramid = BH/3

B is the base area = L^2

B = 5.4²

B = 29.16yd²

H = 6.2yd

Get the volume

volume of the square pyramid = 29.16*6.2/3

volume of the square pyramid = 180.792/3

volume of the square pyramid = 60.26yd³

Hence the volume of the square pyramid to nearest hundredth is 60.26yd³

Answer:

25 = base

Step-by-step explanation:

I searched all of this on YT to try and help

so first we need to know the area of a Trapezoid

A = 1/2h(b + b)

86 = 1/2(18 + b)4

we dont know the base where going to put b

we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.

172 = (18 + b)4

the 4 is multipling so divide it on both ends.

43 = (18 + b)

then do the opposite operation on the 18, by subtracting 18 on both sides.

25 = b

is the base

check the work by plugging it back in

A = 1/2h(b + b)

A = 1/2 4(18+25)

A = 1/2 4(43)

A = 1/2(172)

A = 86in
