Andre and his dad have been fishing for 2 hours. In that time, they have caught 9 blue gills and 1 yellow perch. How many total fish are there?
There are 10 total fish. We are looking at how many fish there are, so we need to add 9 + 1 to get our answer of 10 fish.
The next time Andre gets a bite, what kind of fish do you think it would be?
My prediction is that it will be a blue gill.
How do you know your prediction is more likely to happen?
9 out of 10 times, they have caught a blue gill. This is more probable than 1 out of 10.
Can you make any other predictions?
I would say that Andre will catch less yellow perches than blue gills. This is because the probability of catching a blue gill is greater than catching a yellow perch. I would also say that Andre will catch 5 fish per hour, since he caught 10 fish in 2 hours.
Nate is constructing a tangent line to a circle he drew from a point outside the circle. Once he has the circle and the point is drawn, what is his next step?
Answer:
The next step is to find the point on the circle which makes a tangent line that passes through the outside point.
Step-by-step explanation:
A tangent line to a circle is a line that touches the circle at exactly one point. You need two points to draw a line. You already have one point and the circle, then you need the other point, which lies on the circle. These two points have to lie on the same line. Notice that there are two possible tangent lines.
Answer:
connect the center of the circle to the point outside the circle

58°
Step-by-step explanation:
subtract 32 from 90 and you get the measure of x°
hope this helps
Answer:
58°
Step-by-step explanation:
Since it is 90° angle and one side of the angle is given as 32° , inorder to get the value of angle x we must subtract the given angle that is 32°from 90°by default. Then we will get the value of x as 58°.

Solve the equation
A.-32,32
B.-8’8
C.8
D.32
Answer:
b
Step-by-step explanation:
[tex]\sqrt{64}[/tex]=±8
Answer:
B. -8 and 8
Step-by-step explanation:
To solve this equation, we need to get x by itself. To do this, perform the opposite of what is being done to the equation. Keep in mind everything must be done to both sides of the equation.
x^2=64
x is being squared. The opposite of being squared is taking the square root. Take the square root of both sides.
√x^2=√64
The exponent and square root on the left will cancel, and x will be left by itself.
x=√64
x=±8
The solutions of the equation are x=8 and x= -8
Therefore, the answer is B. -8, 8

Amanda bought a truck for $20,000. The value of the truck depreciates by 7 percent each year. Which of the following functions models this scenario, where x is the number of years
Which is correct:
A) ƒ(x) = x2 – 7x + 20,000
B) ƒ(x) = 20,000 – 7x
C) ƒ(x) = 20,000(1.07)x
D) ƒ(x) = 20,000(0.93)x
Answer:
It would be D
ƒ(x) = 20,000 * (0.93) ^ x

If 2a+1/2a=10 find : 4a2+1/4a2
Answer:
98
Step-by-step explanation:
(2a + [tex]\frac{1}{2a}[/tex] )² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] , thus
10² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] ( subtract 2 from both sides )
100 - 2 = 4a² + [tex]\frac{1}{4a^2}[/tex] , that is

The expression 2(a+b)=−8.1 for certain values of a and b. Find the value of the following expressions for the same values of a and b: −0.5(a+b)
Answer:
Interpreting as: 2(a+b)=-8.1
Input:
2 (a + b) = -8.1
In Given the expression
2( a + b) = 8.1 ..........................(1)
now divide both sides of the first equation by 2 ,
2 (a + b) /2 = 8.1 /2
(a + b) = 4.05
expression -0.5(a + b) ................(2)
simply put the value of (a + b) in (2),
- 0. 5( 4.05) = -0.5 * 4.05
= 2.025
Value of expression is 2.025.

The surface area of a cube is 600 square inches. What is the area of one of its faces?
A.
6 square inches
B.
36 square inches
C.
75 square inches
D.
100 square inches
Answer:
D.
Step-by-step explanation:
area of a square = side^2
area of a cube = 6 x side^2
let the side be a .
6a^2 = 600
=> a^2 = 600/6
=> a^2 = 100
Hence the area of one of its faces is 100 square inches.
or in plain terms without using those formulas,
6 faces of the cube have 600 square inches
=> 1 face of the cube has 600/6 = 100 square inches

Answer: 20 servings
Step-by-step explanation:
From the question, Sara is having a dinner party for four friends and she needs to reduce the serving size of the meatloaf recipe. Sara used the equation x/4=5 . To get the number of servings the recipe originally made, we have to find the value of x.
x/4 = 5
x = 4 × 5
x = 20
This means that the recipe that was used originally made 20 servings.

Steven spent 2 hours and 30 minutes to attend 3 classes. If it took him the same amount of time to attend each class, how long would it take him to attend 5 classes?
Answer:
about 4.17 hours
Step-by-step explanation:
To solve the time for each class, you do 2.5 hours divided by 3. Then you take this value and multiply by 5 since there are 5 classes. After you do this, you should get 4.17 hours roughly.
The expression w^4 – 36 is equivalent to..?
Answer:

2x+3y=12 complete the missing value in the solution to the equation ( 8,)
Answer:
Missing value is -4/3 and whole solution can be written as ( 8,-4/3)
Step-by-step explanation:
Given equation 2x+3y=12
solution ( 8,)
solution is form (x,y) hence in (8,) x is given as 8 while y is missing to find y
we will plug 8 as value of x in equation 2x+3y=12. From this equation we will find the missing value.
2x+3y=12
=> 2*8+3y=12
=> 16 + 3y = 12
=> 3y = 12-16= -4
=> y = -4/3
Thus, missing value is -4/3 and whole solution can be written as ( 8,-4/3)
