A recipe calls for 12 lb of flour for 1 batch. How many batches can be made with each of the following amounts?

1 lb
[ Select ]
34 lb
[ Select ]
14 lb
[ Select ]

Answers

It could be wrong but I'm pretty sure I'm right.

For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

To find these answers take your amount of flour and divide it by the 12 pounds of flour.

Example; 34 divided by 12 = 2.833

Example 2; 14 divided by 12 = 1.66

Answer:For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

if all functions are relations, are all relations functions? Explain your answer

Answers

Answer:

No, because some relations are not functions. Relations are equations that begin with x=, and let's say x=5.

This is not a function because if you graph this line, it is vertical, and functions can't share the same x coordinate point (input) with other y coordinate points (output). There must be one output for every input, meaning that this relation is not a function.

Step-by-step explanation:

No, just because functions are relations Doesn’t mean it’s the same for the other

Answer:

x = 20

Step-by-step explanation:

2x + 2x + 10 = 90

4x + 10 = 90

4x = 80

x = 20

Answer:

Angle AOB is made up of angle AOC and COB.

AOC + COB = AOB

Since AOB is a right angle, it is 90°.

Using the values given, AOC = [tex]2x[/tex] and COB = [tex]2x+10[/tex].

Therefore,

[tex]2x+2x+10=90[/tex]

Subtract 10 from both sides:

[tex]2x+2x+10-10=90-10[/tex]

[tex]2x+2x=80[/tex]

[tex]4x=80[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4} =\frac{80}{4}[/tex]

[tex]x=20[/tex]

Craig went bowling with $25 to spend. He rented shoes for $5.25 and paid $4.00 for each game. What was the greatest number of games Craig could have played?
write an inequality for this problem. then use ur inequality and solve algebraically and explain ur solution

Answers

Answer:

Craig has

$25−$5.25 for shoes. In other words, he has $19.75 Now when you divide this amount by $4.00, you will get numbers of games he played.

$19.75

$4

=4.9375

or only 4 games.

Step-by-step explanation:

Answer: 4 games

Step-by-step explanation: 25-5.25=19.75

19.75 divided by 4 = 4.9375 (but let's say its 4)

Or you could use the subtraction way 19.75 - 4 and continue until you cant subtract it by 4 anymore

What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)? a) -17 b) -11 c) 7 d) 19​

Answers

Answer:

(- 11)

Answer b is correct

Step-by-step explanation:

To find this you can use

y = mx + c

Here,

m = slope

c = y - intercept

( -5, 4) = ( x ,y)

Let us solve now .

[tex]y = mx + c[/tex]

[tex]4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c[/tex]

Therefore,

c = (-11)

That means y - intercept is ( -11 )
