If y = -5, what is the value of 2y+2 - 4

Mathematics

MatroZZZ [7]3 years ago

Answer:

-12

Step-by-step explanation:

Ok so I'm guessing that's a -4 but if its not, please correct me.

y= -5 is going to be plugged into 2y+2-4

This means that <u>2(-5)</u>+<u>2-4</u>=?

2(-5) is the equivalent to 2 times -5, which is -10 (you solve multiplication first because order of operations)

Now, 2-4=-2

So using this, let's combine both equations!

-10+-2=?

?=-12

It's a lot of steps but they get easier the more you do them <3

Approximately what percentage of apple diameters is greater than the 66th percentile? 21. A. 3.4% B. 17% C. 66% D. 34%
astraxan [27]

Answer:

The correct option is D) 34%.

Step-by-step explanation:

Consider the provided information.

If it is given that you scored in the 66th percentile, that means you scored "as well as or better than" 66% of the group.

Here it is given that 66th percentile that means 66% of the data located below the 66th percentile.

That means 100%-66% = 34% of the data located above the 66th percentile,

Thus, the approximately 34% percentage of apple diameters is greater than the 66th percentile.

Therefore, the correct option is D) 34%.

Simplify (5 - p2 - 4q) - ( -2 + q - 3p2) <br> plss hurry!!!!
jonny [76]

Answer:

2p^2−5q+7

Step-by-step explanation:

Let's simplify step-by-step.

5−p2−4q−(−2+q−3p2)

Distribute the Negative Sign:

=5−p2−4q+−1(−2+q−3p2)

=5+−p2+−4q+(−1)(−2)+−1q+−1(−3p2)

=5+−p2+−4q+2+−q+3p2

Combine Like Terms:

=5+−p2+−4q+2+−q+3p2

=(−p2+3p2)+(−4q+−q)+(5+2)

=2p2+−5q+7

Answer:

=2p^2−5q+7

How much cardboard will be needed to make the box? 4 feet by 3 feet with a height of 2 feet
sergiy2304 [10]

Answer:

52 ft²

Step-by-step explanation:

When you are calculating the amount of cardboard needed to make a box, you are trying to the the <u>surface area</u>.

The formula for surface area of a rectangular prism is:

SA = 2(lw + hl + wh)

The dimensions for the box are written l X w X h (length times width times height).

We know:

l = 4

w = 3

h = 2

The units for surface area is the unit squared. Feet squared is ft². Be sure the include the units.

Substitute these numbers into the formula. When solving, solve in the BEDMAS order (brackets, exponents, division and multiplication, addition and subtraction).

SA = 2(lw + hl + wh) u²

SA = 2((4*3) + (2*4) + (3*2)) ft²      Multiply within each smaller bracket

SA = 2(12 + 8 + 6) ft²          Add inside the brackets

SA = 2(26) ft²        Multiply

SA = 52 ft²         Final answer

Therefore 52 square feet of cardboard will be needed to make the box.
