A builder uses 32 wooden slats to make 4 fence panels. Fatima wants to know how many slats are needed for 1 panel. Gerard wants to know how many slats he will need to make 8 panels.
Fatima:How many slats in 1 panel?
Gerard: How many slats for 8 panels?

Answers

Answer:

Fatima: 8 wooden slats. Gerard: 64 wooden slats.

Step-by-step explanation:

For Fatima: You need to divide 32 by 4 to get 8 wooden slats because you need to find out how many slats are for 1 panel.

For Gerard: You need to multiply 32 by 2 to get 64 slats because if you know 32 slats make 4 fence panels, you need to multiply 4 by 2 to get 8, which is double the number, so you need to double 32 too.

36 3⁄4 gallons of water come out of a hose in 15 minutes. Write the ratio in fractional form and determine the water rate in gallons per hour.

Answers

Answer:

Step-by-step explanation:

If 3⁄4 gallons of water come out of a hose in 15 minutes, to calculate the rate of water that comes out in an hour (60 minutes), we will use the expression;

3/4 gallons = 15 minutes

x gallons = 60minutes

cross multiply

15x = 3/4 * 60

15x = 180/4

15x = 45

x = 45/15

x = 3/1

x = 3:1

Hence the water rate in gallons per hour is 3 gallons per hour

Answers

Answer: The answers are in the steps please look carefully.

Step-by-step explanation:

In this given situation, the length of RS plus the length of ST will equal to the length of RT because RS and ST lies on RT. We are given that RS is equal to 2x + 10 and ST is equal to x- 4 , this means that 2x + 10 plus x-4 will equal to 21 because the whole length of RT is 21.

A. Equation: (2x + 10 ) +(x -4) = 21

Now solve the equation for x.

2x + 10 + x -4 = 21 First combine like terms on the left side.

3x + 6 = 21 Subtract 6 from both sides

-6 -6

3x = 15 Divide both sides by 3

x = 5

The value of x is 5.

The length of RS is 2x +10 so since we know the value of x input it into the expression and solve for the real length.

2(5) + 10

10 + 10 = 20

ST is also x -4 so input the value for x and solve for the real length.

5 - 4 = 1

x = 5 , RS = 20 , ST = 1

B. The same applies to B.

RS plus ST has to Equal to RT.

We know the length of RS is 3x -16 and the length of ST is 4x -8 so it has to equal 60.

Equation: ( 3x -16) + (4x - 8) = 60 Solve for x

3x - 16 + 4x -8 = 60

7x - 24 = 60

+24 +24

7x = 84

x= 12

Input 12 in for x and solve for the real lengths

RS = 3(12) - 16

RS = 36 - 16

RS = 20

ST= 4(12) - 8

ST= 48 - 8

ST= 40

x = 12, RS = 20, ST = 40

Step-by-step explanation:

180-80=100 and since the to one is vertical to where the question mark is , it's also 100

Answer:

100°

Step-by-step explanation:

Alternate angles on a cross section of a parallel line are equal. Because 80° is above it, it needs to be the opposite angle. angles on a straight line are 180° so 80+100=180°

(b) one dihedral angle in methyl formate relates the plane containing the o=c–o bonds to the plane containing the c–o–c bonds. identify two structures of methyl formate: one in which this dihedral angle is 0° and the other in which it is 180°.

Answers

Answer:

Step-by-step explanation:

Methyl formate sometimes is also known as methyl methanoate. The removal of an anion from formate result in formic acid. So, we can simply say that methyl formate is a methyl ester of formic acid. Esters are named as alkyl derivates. Methyl formate is a colorless volatile liquid with a pleasant smell that is slightly soluble in water.

However, a dihedral angle is an angle that exists between pairs of chemical bonds separated by a third bond.

From the images attached below, we will see how methyl formate connects to the plane at an angle of 0° and 180°.
