The program director at a botanical garden surveyed 75 of their annual members about the number of times they visit the gardens every month. The table shows the results of the survey. There are a total of 516 annual members. What is the best estimate for the number of annual members that will visit the botanical garden more than 3 times in the next month?
A) 24 annual members
B) 96 annual members
C) 165 annual members
D) 234 annual members
Answer: C) 165 annual members
Step-by-step explanation:
Those who will visit the garden more than 3 times in the next month will be those who visit 4, 5, and 6 or more times.
Out of the 75 surveyed, the total number of those are:
= 9 + 12 + 3
= 24
That would give a percentage of:
= 24 / 75
= 32%
This means that the best estimate for those who will visit more than 3 times is 32%.
Out of the total number of 516, that is:
= 32% * 516
= 165 members
4 times (12-8) + 2^3. (2 to the 3rd power)
Answer:
It's 48. Heres why:
Step-by-step explanation:
Our equation, I believe, is 4[(12-8) + 2³]. We can do the operations in the parenthesis:
4[(4)+8] (12-8 = 4, and 2³ is 8). If we add 4 + 8, we get 12. Multiply 12 by 4, we get 48.
Divide 6.1 and 51.24
Answer:
.119047619
hope this helped
Answer:
8.4
Step-by-step explanation:
51.24 ÷ 6.1 = 8.4
Although, if you were dividing 6.1 by 51.24, you would have a totally different answer, the answer to 6.1 ÷ 51.24 = 0.119047619047619.
A crayon weighs 1/2 ounce. There are 96 crayons in a box. The box weighs 4 ounces. How many pounds do 12 boxes of crayon weigh?
Answer:
39 pounds
Step-by-step explanation:
1) 1/2 + 1/2 = 1 -> this means 2 crayons equals 1 ounce
2) 96/2 = 48 -> 48 oz of crayons *oz means ounces*
3) 48 + 4 = 52 oz -> box + crayons = total weight of box of crayons
4) 52 * 12 = 624 oz
5) 624/16 = 39 lbs -> convert ounces to pounds
I NEED TO REPLACE MY CONCRETE IN 7 YEARS. THE TOTAL COST IS $15,000, HOW MUCH DO I NEED TO SAVE ANNUALLY AT 5%.
9514 1404 393
Answer:
$1,754.57
Step-by-step explanation:
If you put the amount in savings at the beginning of the year, then the balance after 7 years is ...
A = P(1 +r)((1 +r)^7 -1)/r . . . . for payment P at annual rate r for 7 years
15000 = P(1.05)(1.05^7 -1)/0.05 = 8.54911P
Then the amount P that needs to be saved is ...
15000/8.54911 = P = 1754.57
You need to deposit $1,754.57 at the beginning of each year for 7 years to have a balance of $15,000 at the end of 7 years.
_____
If you wait until the end of the year to deposit the money, the amount will need to be 5% higher: $1,842.30.

If the terminal point of ø is (-1,0), what is tan ø?
The SOH CAO TOA identity is used to determine the acute angles of a right triangles. The terminal point of ø is (-1,0), what is tan ø is 0
Given the terminal point (-1, 0), the value of tanø is expressed as:
tanø = opposite/adjacent
tanø = y/x
From the coordinate given:

Answer:
44 units² or 44 units squared
There really isn't a preference of units, like inches or meters, so you can add that in.
Step-by-step explanation:
Haha, this is what we're doing in class!
Okay, so the formula for a trapezoid is A= ½ (b1+b2) h
14= b1
8= b2
Add them... You get 22. Multiply that by the height, which is 4. You should get 88. Then divide by 2. You should get 44.

The product of two consecutive negative even integers is 24. Find the largest integer.
Answer:
-4
Step-by-step explanation:
ok negative times negative = positive
and factors of 24 are
1,2,3,4,6,8,12,24
4 x 6 are the two consecutive EVEN numbers
so turn it to negative
-4 x -6 = 24
The largest is -4
can you guys help me with this equation plzzzzzz
Answer:
b = 1/3
Step-by-step explanation:
Here, we want to solve for the value of b
From the question, we have that;
4^(3b-3) = 1/16
4^(3b-3) = 16^-1
4^(3b-3) = 4^2(-1)
4^(3b-3) = 4^-2
Since base are equal, equate the powers
3b - 3 = -2
3b = -2 + 3
3b = 1
b = 1/3
8. Subtact (7x – 10) – (-6x – 8).
Answer:
13x - 2
Step-by-step explanation:
7x - -6x = 7x + 6x = 13x.
-10 - -8 = -10 + 8 = -2
13x - 2
Answer:
13x - 2
Step-by-step explanation:
( 7x - 10 ) - ( -6x - 8 )
First, distribute the minus sign outside of the second parenthesis. Multiply each term within the second parenthesis by the minus sign.
( 7x - 10 ) + ( (-1)(-6x) + (-1)( -8))
Simplify,
( 7x - 10 ) + ( 6x + 8 )
Remove parenthesis,
7x - 10 + 6x + 8
Simplify, combine like terms,
7x - 10 + 6x + 8
13x - 2

An Isoceles Triangle has base 6cm long and the opposite angle to the base is 50 degrees l. What is the size of the other angle?
Answer:
65°
Step-by-step explanation:
From the question,
The base angle of an isoceles triangle are equal.
Let the value of the base angles = x°
Sum of angle in a triangle = 180°
⇒ x°+x°+50° = 180°
⇒ 2x°+50° = 180°
⇒ 2x° = 180°-50°
⇒ 2x° = 130°
⇒ 2x°/2 = 130/2
⇒ x° = 65°.
Hence, the size of the other angles is 65°

16 What value could you put in place of the x to make it a function? * (8, 7) (7,-6) (-4,5) (x, 9)
a) 8
b) 7
c) 9
d) -4
Answer:
(c) 9
Step-by-step explanation:
You can't have a repeated x-value in a function.
8 is taken by (8, 7)
7 is taken by (7,-6)
-4 is taken by (-4, 5)
9 is the only number that is not taken by any other point yet.
Remember that for a relationship to be a function it can't have repeated x-values. However, it doesn't matter to have the same x and y values!

Answer:
x = 132 degrees
Step-by-step explanation:
To help explain, lets add some letters to designate those line intersections.
Starting at x, label that intersection O, then go up-right to that intersection and label that P, then go down-right to that intersection and label that Q, then go up-right and name that R, then go down-right and label that S, finally go right to that intersection and label that T.
Angle TRS = 12 degrees because isosceles triangle so TRS = a = 12 degrees.
Angle RST = 180-12-12 = 156 degrees.
Angle QSR is supplementary to RST so it is 24 degrees.
Angle RQS = 24 degrees because isosceles.
Angle QRS = 180-24-24 = 132 degrees.
Angle PRQ = 180-12-132 = 36 degrees.
Angle PRQ = 36 degrees because isosceles.
Angle PQR = 180-36-36 = 108 degrees.
Angle PQO = 180-24-108 = 48 degrees.
Angle POQ = 48 degrees because isosceles.
Angle x = 180 -48 = 132 degrees because it is supplementary.

3(4y + 7) = 69
full answer
Answer:
y=4
Step-by-step explanation:
First, you should simplify this equation. To do that, we need to multiply 3 by 4y and 3 by 7. This will make the equation 12y+21=69. Subtract 21 from both sides to isolate y. This will make the equation 12y=48. You want the y to be by itself so you have to divide 12 by each side to get y=4. Therefore, the answer is y=4.
Hope this helps
That is the answer...
