Answer:

3.6 and 2

Step-by-step explanation:

Given R is inversely proportional to A then the equation relating them is

R = [tex]\frac{k}{A}[/tex] ← k is the constant of proportion

To find k use the condition R = 12 when A = 1.5, that is

12 = [tex]\frac{k}{1.5}[/tex] ( multiply both sides by 1.5 )

18 = k

R = [tex]\frac{18}{A}[/tex] ← equation of proportion

(a)

when A = 5, then

R = [tex]\frac{18}{5}[/tex] = 3.6

(b)

when R = 9, then

9 = [tex]\frac{18}{A}[/tex] ( multiply both sides by A )

9A = 18 ( divide both sides by 9 )

A = 2

Answer:

option 4

Step-by-step explanation:

-3.4x + 4.7 - (3 + 2.9x) = -3.4x + 4.7 - 3  - 2.9x  (combine like terms)

                                   = -3.4x - 2.9x + 4.7 - 3

                                  = - 6.3x + 1.7

If two number have same sign, add and put the common sign for the answer.

If two numbers have different sign, subtract and the answer will have the sign of the bigger number

Answer:

$2090

Step-by-step explanation:

The time is 6/12 since it is in months and not years

Interest = [tex]\frac{Principal * Rate * Time}{1}[/tex]

              =[tex]\frac{2000 * 9 * 6}{100*12}[/tex]

              = $90

This means her balance will be $(2000+ 90) = $2090

The answer is letter D

Answer: D also, can i have brainliest?

solution:

The other 2 sides added have to be greater than 13

Option A: 5 + 8 = 13. 13 is not greater than 13 so it's not the answer.

B: 6 + 7 = 13. Same thing as option A

C: 7 + 2 = 9. 9 is less than 13 so not the answer.

D: 8 + 8 = 16. 16 is greater than 13 so D is the correct answer.

Answer:

8 cm and 9 cm

Step-by-step explanation:

D

Answer:

Step-by-step explanation:

by making the length an inequality x height will be 1.5x

Volume=1/3BA xh

X×X×1.5X 1/3=2304

0.5x3=2304

X³=2304÷0.5

X³=4608

X=³√4608

X=16.64cm

H=16.64x1.5=24.96cm

The height of the square pyramid is equal to 24.96 cm.

A square pyramid in geometry is a pyramid with a square base. A right square pyramid is one in which the peak is perpendicular to and above the square's centre.

Given that the height of a square pyramid is one-half the length of each side. The volume of the pyramid is 2,304 cubic inches.

The height of the square pyramid will be calculated as,

Volume=1/3BA xh

X×X×1.5X 1/3=2304

0.5x3=2304

X³=2304÷0.5

X³=4608

X=³√4608

X=16.64cm

H=16.64x1.5=24.96 cm

Therefore, the height of the square pyramid is equal to 24.96 cm.

Answer:

First number = 25

Second number  = 14

Step-by-step explanation:

Let the numbers be x & y

The sum of twice the first and thrice the second is 92

2x + 3y = 92   -------------------(I)

Four times the first exceeds seven times the second by 2​

4x - 7y = 2  --------------------(II)

Multiply  equation (I) by -2 and then add the equations

(I)*-2          -4x - 6y = -184

(II)               4x - 7y = 2      { Now add, thus x will be eliminated}

                      - 13y = -182 {Divide both sides by -13}

y = -182/-13

y = 14

Plugin the value of y in equation (I)

2x + 3*14 = 92

2x + 42 = 92

       2x = 92 - 42

       2x = 50

        x  = 50/2

x = 25

First number = 25

Second number  = 14

Answer:

14 bags

Step-by-step explanation:

Total potato grown on Pat's potato farm = 490 pound

Fraction of potato delivered to vegi stand = 3/7 of total potato

Therefore,

Potato delivered to Vegi stand in pound = 3/7 of Total potato grown

                                                                     =  3/7 of 490 = 3/7 * 490

                                                                     = 210

Thus, 210 pound potato is delivered to vegi stand

___________________________________________

Fraction of potato delivered to local grocery store = 2/3 of  potato delivered to Vegi stand

Therefore,

Potato delivered to local grocery store in pound = 2/3 of  potato delivered to Vegi stand

                                                                     =  2/3 of 210 = 2/3 * 210

                                                                     = 140

Thus, 140 pound potato is delivered to local grocery store.

____________________________________________________

Half of the potatoes delivered were packaged into 5 pound bags

Half of 140 pound potato is delivered to local grocery store will be

140/2 = 70 pounds.

Thus, 70 pounds potatoes were packed in 5 pound bags.

Let the the no of 5 pounds bag be x.

if one bag has 5 pound potatoes then

x bag will have 5*x = 5x pound potatoes,

but it is given that  70 pounds potatoes were packed in 5 pound bags.

thus,

5x = 70

x = 70/5 = 14

Thus, 14 bags were packed by grocery store package.

Answer:

6 teaspoons

Step-by-step explanation:

2 teaspoons = 1/3 tsp of salt

6 teaspoons = 1 tsp of salt

This was done by multiplying 2 by 3 since 3 thirds (3/3) make one whole.

So if 2 teaspoons are used for 1/3 teaspoon of salt, 4 teaspoons would be used for 2/3 teaspoon of salt and 6 teaspoons would be used for 1 teaspoon of salt.

Answer:

10

Step-by-step explanation:

Align the data from smallest to largest

3,8,9, 11, 14,  15*

The median is the middle number

3,8,9,     11, 14,  15*

It would be between the 9 and 11 since there is an even number of numbers

(9+11)/2 = 20/2 = 10

The median is 10

Solution:

Arranging the data in ascending order:

3,8,9,11,14,15

N(total number of items)=6

Median=(N+1/2) th item

=(6+1/2)th item

=(7/2)th item

=3.5th item.

Median=3rd item+4th item/2

=9+11/2

= 20/2

=10

Median =10

Answer:

184 square inches

Step-by-step explanation:

Bases: 4 in × 5 in × 2 bases = 40 in²

Smaller pair of lateral faces: 4 in × 8 in × 2 faces = 64 in²

Larger pair of lateral faces: 5 in × 8 in × 2 faces = 80 in²

40+64+80=184 in²

The surface area of the box is 184 in² or 184 square inches.

Answer: B) 184 Square Inches

Step-by-step explanation:

To find the surface area of the box we have to use the formula, the formula is  A = 2wl + 2lh + 2hw....

To find the front and the back we have to multiply the width and the length...

8 * 5 = 40 + 40 = 80

To find the right and the left we have to multiply the length and the height...

8 * 4 = 32 + 32 = 64

To find the bottom and the top we have to multiply the height and the width...

4 * 5 = 20 + 20 = 40

40 + 64 + 80 = 184

The surface is 184 square inches, I hope this helps!

Answer:

U = 48

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

x+21 + x+23 + x+61 = 180

Combine like terms

3x + 105 = 180

Subtract 105 from each side

3x+105-105 = 180-105

3x = 75

Divide by 3

3x/3 = 75/3

x = 25

We want angle u

x+23

25+23

48

Answer:

48

Step-by-step explanation:

All interior angles of a triangle add up to 180.

[tex](x+21)+(x+23)+(x+61)=180[/tex]

If you wanted to you could subtract 21, 23, and 61 from 180.

[tex](x+21)+(x+23)+(x+61)=180\\x+21+x+23+x+61=180\\3x+105=180\\3x=75[/tex]

Then take then number that's left and divide it by three, since they are all in addition to the same variable.

[tex]\frac{3x}{3}=\frac{75}{3}\\ x=25[/tex]

Then add 25 to 23 which is 48.
