Find The Value Of The Variable If Necessary Round Your Answer To The Nearest Tenth

Answers

Answer 1

Answer:

x = 24.7

Step-by-step explanation:

Here, we want to find the value of x

To do this, we are to use the appropriate trigonometric ratio

From what we have;

9 faces the angle given as it is the opposite, x is below and it is the adjacent

The trigonometric identity that links opposite to adjacent is the tan which is the ratio of former to latter

Thus, we have that;

tan 20 = 9/x

x = 9/tan 20

x = 24.7

If you have 24 dozen Shamrock cookies horseshoe cookies mint cupcakes and you sold four times as many cupcakes as cookies and three times as many cookies as Shamrock cookies how many mint chocolate chip cupcakes did they sell

Answers

Answer:

144

Step-by-step explanation:

108 plus 36 then you will get 144

They sold a total of 18 dozens of mint chocolate chip cupcakes.

What is an equation?

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of shamrock shaped cookies, y represent horseshoe shaped cookies and z represent mint chocolate cupcakes.

He sold a total of 24 dozens, hence:

x + y + z = 24  (1)

The sold 4 time shamrock shaped cookies as cupcakes, hence:

z = 4x   (2)

Also, they sold three times as many cookies as Shamrock cookies:

x = 3y   (3)

From the equations:

x = 4.5, y = 1.5 and z = 18

They sold a total of 18 dozens of chocolate chip cupcakes.

Sophia bought a fish tank with the dimensions shown below.

Which is closest to the number of cubic FEET of water needed to fill the fish tank? Hint: There are 1,728 cubic inches in 1 cubic foot.

A
0.8 cubic feet
B
2.5 cubic feet
C
240.0 cubic feet
D
1,440 cubic feet

Answers

The answer is D. hope this helpss!

0.8 cubic feet is closest to the number of cubic feet of water needed to fill the fish tank.

What is Three dimensional shape?

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

To find the number of cubic feet of water needed to fill the fish tank

we need to first convert the dimensions of the tank from inches to feet.

since the conversion factor between cubic inches and cubic feet is 1,728.

Length in feet = 20 inches ÷ 12 inches/foot

= 1.67 feet

Height in feet = 12 inches ÷ 12 inches/foot

= 1 foot

Width in feet = 6 inches ÷ 12 inches/foot

= 0.5 feet

The volume of the fish tank in cubic feet is:

Volume = length × height × width = 1.67 feet × 1 foot × 0.5 feet = 0.835 cubic feet

Hence,  the number of cubic feet of water needed to fill the fish tank is 0.8 cubic feet, Option A is correct.

Step-by-step explanation:

4 = x - 5

x = 9

3(9) + 4 = 31
