find 2 numbers when multiplied by each other = 100
sqrt(100) = 10
since the equation has a minus sign
the answer would be (x+10)(x-10)
When we are factoring squared binomials, there’s a pretty simple technique to solving for these.
First, square root the first term (x^2). We get x. Now, let’s square root our second term (100), which we get 10.
Put our square-rooted terms into parenthesis; (x + 10)
Since we have a negative sign before 100, we need to add a second parenthesis with the same terms, but 10 now needs to be negative; (x - 10)
Put these two parenthesis next to eachother, and now we have our answer, as we cannot simplify it anymore;
(x - 10)(x + 10)

the graph shows the height of 10 sunflower grown in pjs garden
Answers
Answer:
B. [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
We have been given a graph that shows the height of the 10 sunflowers grown in PJ's garden. We are asked to find the probability that the 11th flower will be at least 60 inches.
[tex]\text{Probability}=\frac{\text{Total number of favorable outcomes}}{\text{total number of possible outcomes}}[/tex]
From the given experiment we can see that there are 5 sunflowers with height more than or equal to 60 inches, so total number of favorable outcomes is 5.
Since there are total 10 sunflowers, so total number of possible outcomes is 10. Upon substituting our given values in probability formula we will get,
[tex]P(\text{The 11th plant will be at least 60 inches})=\frac{5}{10}[/tex]
[tex]P(\text{The 11th plant will be at least 60 inches})=\frac{1}{2}[/tex]
Therefore, the probability that 11th plant will be at least 60 inches is [tex]\frac{1}{2}[/tex] and option B is the correct choice.

there are 6 photos on the wall.there are 2 photos in each row. how many rows of photos are there
Answers
There are 3 rows of photos on the wall.
Explanation:To determine the number of rows, we need to divide the total number of photos by the number of photos in each row. In this case, there are 6 photos and 2 photos in each row. So, we divide 6 by 2:
6 ÷ 2 = 3
Therefore, there are 3 rows of photos on the wall.

the number of students enrolled at a college is 15,000 and grows 4% each year
Answers
The words regarding growth factor for the given blanks are a) 15000, b) 0.04, 1.04, c) 15000 × 1.04 and d) y = 15000(1.04)ˣ
What is growth factor?The growth factor refers to a specific part of an exponential function. This is the base of an exponential function.
Given is a black statement, we need to find the words to be filled in them,
a) The number of students enrolled at a college is 15,000 and grows 4% each year,
Since, the number of students at time of enrollment is 15000, therefore, the initial amount = 15000
b) The percent rate of change is 4%, so the growth factor b is 1 + ______ = ______
Here, the percent rate of change is for growth, therefore,
the growth factor = 1 + 0.04 = 1.04
c) To find the number of students enrolled after one year, you calculate
15,000....
To find the number of students after one year = 15000 × 1.04
d) Complete the equation y = ?
The equation for the same will be =
y = 15000(1.04)ˣ
Hence, the words regarding growth factor for the blanks are a) 15000, b) 0.04, 1.04, c) 15000 × 1.04 and d) y = 15000(1.04)ˣ

a concrete patio is 5 2/3 feet wide. it has an area of 36 5/6 square feet. Is the concrete slab long enough to fit a 7 foot picnic table without placing the table along the diagonal of the patio? Explain
Answers
Answer:
No
Step-by-step explanation:
W are given that a concrete patio is [tex]5\frac{2}{3}[/tex] feet wide
and area of of concrete patio is [tex]36\frac{5}{6}[/tex]
We have to find out the length of concrete slab is 7 foot or not.
We know that area of rectangle =[tex]l\timesb[/tex]
Let length of concrete patio =x foot
Breadth of concrete patio =[tex]\frac{17}{3}[/tex] feet
Area of concrete patio =[tex]\frac{221}{6}[/tex]
Using formula
[tex]\frac{221}{6}=\frac{17}{3}\times x[/tex]
[tex]\frac{221}{6}\times \frac{3}{17}=x[/tex]
[tex]x=\frac{13}{2}[/tex] foot=6.5 foot
Hence, length of concrete slab is 6.5 foot not 7 foot.Therefore, 7 foot picnic table will no fit.
The concrete slab is not long enough to fit the picnic table.
The concrete patio is in the shape of a rectangle. A rectangle is an object that has four sides. The diagonal is the length from angle of the rectangle to the other angle of the rectangle.
The area of a rectangle = length x width
length = area / width
[tex]36\frac{5}{6}[/tex] ÷ [tex]5\frac{2}{3}[/tex]
Convert to improper fractions
[tex]\frac{221}{6}[/tex] ÷[tex]\frac{17}{3}[/tex]
[tex]\frac{221}{6}[/tex] x [tex]\frac{3}{17}[/tex] = [tex]\frac{13}{2}[/tex]
length = 6.50 feet
The length of the patio is less than the length of the picnic table.

Team Tool Bella canoed 15 3/4 miles in 5 1/4 hours. What was their average speed in miles per hour

Convert mixed numbers to an improper fractions
[tex]total\ distance=15\frac{3}{4}\ miles=\frac{15*4+3}{4} =\frac{63}{4}\ miles[/tex]
[tex]time=5\frac{1}{4}\ hours=\frac{5*4+1}{4} =\frac{21}{4}\ hours[/tex]
Divide the total distance by the time
[tex]\frac{(63/4)}{(21/4)} =\frac{63}{21} =3\frac{miles}{hours}[/tex]

how many 5/16 foot pieces of wood can you cut from a board that is 1 9/16 feet long
Answers
So 5/16 foot pieces from a 1 9/16 feet long piece of wood. OK so this is easy what we do is we do 1 9/16 divided by 5/16 which we switch 1 9/16 to 25/16 divided by 5/16 so we keep 25/16 switch the division symbol to a multiplication symbol and flip the 5/16 so now we have 25/16*16/5 which is 400/80 we can simplify to 5. So a 1 9/16 foot long board can make 5 5/16 pieces of wood.

Answer:
Option B is correct
all the powers have the value of 1 because the exponent is zero
Step-by-step explanation:
Using the exponent rule:
[tex]a^0 = 1[/tex] for any real number a.
Given that:
[tex]4^0 = 1[/tex]
[tex](-2)^0 = 1[/tex]
[tex](\frac{1}{3})^0 = 1[/tex]
