The number 49 has two square roots: 7 and _____
Answer:
-7
Step-by-step explanation:
Square numbers always have two possible roots: a positive and negative root. This is because two positive numbers multiply to make a positive number and two negative numbers also multiply to make a positive number
-7 × -7 is still 49, just like 7 × 7

HELP PLEASE I DON´T UNDERSTAND RATIOS!
Answer:
Jake made 7 bead strings
Step-by-step explanation:
The ratio is 2:6 next would be 4:12 then 6:18 and so on. You just add what you started with to the corresponding side. 8:24, 10:30, 12:36, 14:42. The right side is 3x the left side.
Answer:
Step-by-step explanation:
You don't really need to use ratios for this question. You need to understand that for each necklace he uses 2 red and 6 whites.
Let the number of necklaces he can make = x
The total number of beads = 56
2x + 6x = 56
8x = 56 Divide by 8
8x/8 = 56/8
x = 7
So the number of necklaces possible is 7.
If you insist on doing this with ratios then you could do it as
2/8 = x/56 What this means is that 2 reds to the total = x / 56. The 56 is the total number of beads used. The x represents the number of reds.
2/8 = x/56 Cross multiply
2 * 56 = 8x Divide both sides by 8
2 * 56/8 = x
x = 14.
That means of the 56 beads used, 14 of them are red.
6/8 = y / 56 Cross multiply
6*56 = 8y
336 = 8y Divide by 8
336/8 = 8y/8
y = 42
This means that 42 beads were white
The total is 56. But here's the catch. The highest prime common to both is 7 and that's how many necklaces can be made.

Enrollment at a golf academy has grown exponentially since the academy opened. A graph depicting this growth is shown. Determine the percentage rate of growth.An exponential graph has Time in Years on the x-axis and Enrollments on the y axis. A curve that rises from left to right begins at zero comma fifteen and passes through four comma seventy-five.a. 1.5%b. 5%c. 50%d. 0.5%
Applying the points given, it is found that the growth rate of the exponential function is:
c. 50%
An exponential function has the following format:
[tex]y = a(1 + r)^x[/tex]
In which:
a is the initial value, that is, the value of y when x = 0.r is the growth rate, as a decimal.In this problem:
The curve begins at (0,15), thus a = 15.It passes through (4, 75), which means that when [tex]x = 4, y = 75[/tex], and this is used to find r.[tex]y = a(1 + r)^x[/tex]
[tex]75 = 15(1 + r)^4[/tex]
[tex](1 + r)^4 = 5[/tex]
[tex]\sqrt[4]{(1 + r)^4} = \sqrt[4]{5}[/tex]
[tex]1 + r = 1.4953[/tex]
[tex]r = 1.4953 - 1[/tex]
[tex]r = 0.4953[/tex]
Thus, approximately 50%, option c.

Mental Math Using the slope formula, find the slope of the line through the points and . Use pencil and paper. Explain how you can use mental math to find the slope of the line. slope is 0,0 and 2,4
Answer:Slope is 2, assuming "0,0 and 2,4" is meant to read (0,0) and (2,4) for the 2 points.
Step-by-step explanation:
The slope is the Rise (change in y) over the Run (change in x). I can see the change in y is 4 (it goes from 0 to 4) and the change in x for this interval is 2 (goes from 0 to 2, or 2-0 = 2). Rise (4) over Run (2) is slope 2. 4/2 = 2 slope.

You put 56 green marbles and 24 yellow marbles into bags. Each bag has the same number of green marbles and the same number of yellow marbles. What is the greatest possible number of bags you can make using all the marbles? How many green marbles are in each bag? How many yellow marbles?
Answer:
8 bags
7 green marbles and 3 yellow marbles
Step-by-step explanation:
Find the GCF of 24 and 56
24 = 4 x 6
= 2 x 2 x 2 x 3
56 = 7 x 8
= 7 x 4 x 2
= 7 x 2 x 2 x 2
The common factors are - 2 x 2 x 2, which is 8.
So the greatest number of bags they can make is 8
Divide the amount of marbles by the number of bags
24 yellow marbles and 8 bags, so 24/8 is 3
56 green marbles and 8 bags, so 56/8 is 7

what is the differences in length between a 1 1/4 inch butten and a 3/8 inch button
Answer:

Step-by-step explanation:
A theater has 30 rows of seats. There are 22 seats in the first row, 26 in the second row, 30 in the third row, etc. How many people will the theater hold ?
Arithmetic Sequence
rows ---------32-n
first term ------------26-----------a
d---------------------------4
Sn = n/2( 2a+(n-1)d)
=32/2 (2*26+(31)4)
=16(52+124)
=16(176)
=2816 seats
If theater has 30 rows of seats, then the number of people that the theater will hold is 2400 people.
To find out how many people the theater will hold, we need to calculate the total number of seats across all 30 rows. Since the number of seats increases by 4 for each successive row, we can treat this as an arithmetic sequence.
The formula to find the sum of an arithmetic sequence is = (n/2) × (first term + last term),
where n = number of terms and the first and last terms are given,
In this case : First term = 22,
Last term = 22 + (30 - 1) × 4 = 22 + 116 = 138,
Number of terms (rows) = 30,
Sum = (30/2) × (22 + 138) = 15 × 160 = 2400;
Therefore, The theater will hold 2400 people.
