Answer:

  (1, 5)

Step-by-step explanation:

The midpoint of a line segment has coordinates that are the average of the end-point coordinates.

  M = (X + Y)/2 = ((-3, 4) +(5, 6))/2 = (-3+5, 4+6)/2 = (2, 10)/2

  M = (1, 5)

The midpoint is (1, 5).

Answer

Step-by-step explanation:

Let's solve for z.

a(t+z)=45z+67

Step 1: Add -45z to both sides.

at+az+−45z=45z+67+−45z

at+az−45z=67

Step 2: Add -at to both sides.

at+az−45z+−at=67+−at

az−45z=−at+67

Step 3: Factor out variable z.

z(a−45)=−at+67

x - 4 = 10.3 EQUATION

SOLUTION:

x = 10.3 + 4

x = 14.3

Answer: x = 10.3 ÷ 4

Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.

Answer:

352 lbs is correct

Step-by-step explanation:

They did estimate correctly. for how to do this look below:

So we have a elephant that gains 22 pounds every week and they estimated that at 16 week she would be at 352 lbs

22 which was current pounds at the time and she would keep gaining that every week for 16 weeks

So weight times weeks

22*16

22*16= 352

Step-by-step explanation:

The die is rigged, so "not 3" is not a possibility.  Ruling out those branches of the tree, there are 4 possible outcomes, one of which is the desired outcome.  So the probability is 1/4.

A fair die has six sides that are equally likely, so the probability of rolling more than 2 is always 4/6.  The outcome of the first roll does not effect the outcome of the second roll.

Answer:

4%

Step-by-step explanation:

Percentage = Number of boys who named pizza [tex]\div[/tex] Total number of boys [tex]\times 100[/tex]

Percentage = [tex]\frac{24}{600} *100=0.04*100=4[/tex]

Thus, 4% of the boys named pizza as their favourite food.

Answer:

The minimum number of pounds they need to collect is 78

Step-by-step explanation:

27/0.35 = 77.7

but in this specific problem  you can't have less than part of a pound, so the final answer would be 78 pounds

A soda cans like a cube with straight on top

angle DBC = 38° ( Alternate Interior Angles )

angle ABD = 38° ( Alternate Interior Angles )

2 (angle ADC) = angle ABC

or, 2 (angle ADC) = 38° + 38°

or, 2 (angle ADC) = 76°

or, angle ADC = 76/2 = 38°

x = 38°

Janel can make 12 bracelets. The quotient of 12 and remainder of 24 means that Janel can make 12 bracelets but does not have enough beads for 13 bracelets.

Hope it helps

lovelymoonlight

Janel can make total of 12 bracelets.

One of the four fundamental operations, along with addition, subtraction, and multiplication, is division. A number is split in the straightforward action of division.

The following dividend formula can be used to find the dividend if the values of the divisor, quotient, and remainder are provided.

Dividend = Divisor x Quotient + Remainder

Janel has total number of beads = 600.

Beads required to make one bracelet = 48.

To calculate the number of beads divide total number of beads by 48.

Beads = 600/48

Quotient comes out as 12 and remained comes out as 24.

Therefore, the total number of bracelets can made is 12.

After completion of 12 bracelets 24 beads will left.

Answer:

Days of snowfall

Step-by-step explanation:

the y- axis

Answer:

1. No vertical compression or stretching but will open up downward.

2. 1/4 vertical stretch

3. 4 vertical compression

Step-by-step explanation:

Any time your dealing with vertical stretching or compression it will always be the number before the parentheses.

So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression

2. Is the 1/4 is a vertical stretch

3. 4 is a vertical compression.

Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be.

Answer:

k = - 6

Step-by-step explanation:

Since (x - 2) is a factor then x = 2 is a root

Substitute x = 2 into the polynomial and equate to zero, that is

2³ + k(2)² + 12(2) - 8 = 0

8 + 4k + 24 - 8 = 0

4k + 24 = 0 ( subtract 24 from both sides )

4k = - 24 ( divide both sides by 4 )

k = - 6
