Felix and Julyssa are computing 3 + 4 x 4. Feliz says the answer is 28. Julyssa says the answer is 19. Who is right? Explain.

Answers

SUBTRACTION

Answer 2

Julyssa is right.
We know this because in bidmas, multiplication comes first, so 4 x 4 is done first.
So 4 x 4 = 16
And 16 + 3 = 19

The fish tank is 80% full. After
adding stones to the bottom of the tank,
the tank is 92% full. What is the volume
of the stones?

Answers

Answer:

12%

Explanation

Because the fish tank is 80% and when the stone is put in the water the water is filled 92% so that means that the water rises 12%

If the tank was at 80% and then 92% after adding stones you could subtract 92-80 which would give you 12. the volume of the stones would be 12%

(GIVING BRAINLIEST TO FIRST CORRECT ANSWER!!)
find the volume.

Answers

Answer:

113.1 m^3

Step-by-step explanation:

Formula

volume = (4/3) * π * r³

What value of y makes the equation 6(x-4)+2 = 36/4 true?

Answers

Answer:

31/6

Step-by-step explanation:

36/4=9

6x-22= 9

6x= 9+22

substitute 6x=31= 31/6

Answer:

x = 31/6

Step-by-step explanation:

first lets isolate the equation which equals, 6x-24+2 = 9

I got 9 from 36/4, divide top and bottom by 4 = 9

Next add the numbers, 6x -24+24= 9 turns into 6x-22= 9

Now move the -22 to the side the 9 is, 6x= 9+22

and now we can solve and substitute, 6x=31, which gives us 31/6

Find the missing angle measure.

Will give brainliest if possible!!

Answers

Answer: 35°

Step-by-step explanation:

Step #1: Write the 'triangle sum theorem' for the triangle which is:

m∠A + m∠B + m∠C = 180°

Step #2: Substitute the given angle measures

40° + 105° + m∠C = 180°

Step #3: Simplify.

m∠C + 145° = 180°

Subtract 145° from both sides.

m∠C = 35°

So, the measure of the missing angle (x) is 35°.

Jorge bought 8 pounds of ground beef for $3.29 a pound. About how much did he pay altogether?

Answers

Answer:$24

Step-by-step explanation:

Answer:

Answer:

B. 150 ft

Step-by-step explanation:

Perimeter of a rectangle = 2(Length) + 2(Width)

Here, we are given the perimeter and width and we want to find the length

We can do so by plugging in what we are given into the perimeter formula and solving for length.

Perimeter = 2(Length) + 2(Width)

Perimeter = 450 and Width = 75

450 = 2(Length) + 2(75)

We now solve for length

==> simplify multiplication 2(75) = 150

450 = 2(Length) + 150

==> subtract 150 from both sides

300 = 2(Length)

==> divide both sides by 2

150 = Length

And we are done!

The answer is B 150ft

During gym class, Lenny, Lonnie, and Lainey measure the length of their long jumps. Lenny’s jump is ⅔ times the length of Lainey’s, and Lonnie’s jump is 1⅓ times the length of Lainey’s. Whose jump is the longest? Why? pls help!!

Answers

Answer: Lonnie’s Jump

Step-by-step explanation:

(They just had to give three names that all started with L.)

Since Lenny's jump is ⅔ times the length of Lainey’s, we can tell that Lenny's jump won't be the longest because it is already smaller than Lainey's.

Since Lenny is now out of the picture, let us look at Lonnie and Lainey. Lonnie’s jump is 1 ⅓ times the length of Lainey’s. Since Lonnie's jump is longer than Laniey's, Lonnie's jump is the longest jump.

Prior to the separation, the male minnows all had a moderate number of spots.Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots.After many generations, the two minnow populations evolved into different species and could no longer interbreed.Fish Species Average # of SpotsOriginal Species four to sixNew Species 1 zero to twoNew Species 2 eight to tenWhich of the following best describes why the two minnow populations evolved into separate species?
