Answer:
one blue triangle is equal to 4
x = 4
Step-by-step explanation:
ok so lets say one red circle is equal to y so
y = 2
there is 4 circles so it would be
4y = 4 * 2 = 8
then the blue triangles are x and are equal to
2x = 2 * x = ?
8 / 2 = x = 4
x = 4

Find the equation of the exponential function represented by the table below:
x у
0 0.01
1 0.02
2 0.04
3 0.08
Answer:
y = 0.01 * 2ˣ
Step-by-step explanation:
f(x) = xⁿ
0: 0.01 = 0.01 * 2⁰ = 0.01 * 1 = 0.01
1: 0.02 = 0.01 * 2¹ = 0.01 * 2¹ = 0.02
2: 0.04 = 0.01 * 2² = 0.01 * 2² = 0.04

Line R is represented by the following equation: x + y = 2
Which equation completes the system that is satisfied by the solution (1, 1)?
2x + y = 2
4x - 2y = 2
2x - 2y = 2
x + y= 4
Answer:
4x-2y=2
Step-by-step explanation:
Line R is represented by the following equation:
x+y=2
We need to choose another system of equation of x+y=2
whose solution is (1,1)
The equation must be satisfy the point (1,1)
Option 1: 2x+y = 2
Put x=1 and y=1
2(1)+1 = 3
3 ≠ 2
False
Option 2: 4x-2y=2
Put x=1 and y=1
4(1) - 2(1) = 2
2 = 2
True
Option 3: 2x-2y=2
Put x=1 and y=1
2(1) - 2(1) = 0
0 ≠ 2
False
Option 4: x+y=4
Put x=1 and y=1
1+1 = 2
2 ≠ 4
False
Hence, The system of equation is 4x-2y=2

Deondra surveyed 240 of the students in her school about their favorite color.
Students could choose between purple and blue. 15% said their favorite color was
blue. How many students' favorite color was purple?
Answer:
the answer is 180 students.
Step-by-step explanation:
I got this by subtracting 15 by 100 and got 75. This means 75% chose purple. Then you take 75% of 240 and that's your answer

9x-12=3x show your work
Answer:
x=2
Step-by-step explanation:
given 9x-12=3x we want to solve for x
To do so we need to isolate the variable using inverse operations
to get rid of the 9x we subtract each side by 9x
9x - 9x cancels out
3x - 9x =-6x
now we have
-12=-6x
now we want to get rid of the -6
to do so we divide each side by -6
-6x/-6=x
-12/-6=2
we're left with x=2
Answer:
9x=3x+12
9x-3x=12
9x-3x=12
6x=12
x=2
solution
x=2

Answer:
Lateral surface area = 280 square inches
Step-by-step explanation:
Lateral surface area of a prism = (Perimeter of the base) × height of the prism
Perimeter of the base = 8 + 15 + 17
= 40"
Height of the prism = 7"
Therefore, Lateral surface area of the prism = 40 × 7
= 280 square inches

Kara is sorting buttons by length for a craft project.The line plot shows of each button.If kara lines up all the 3/4 inch buttons What would be the total
Required picture attached below :
Answer:
2 1/4 inches
Step-by-step explanation:
From the line plot Given ;
The frequency or number of 3/4 inch button is 3

Theoretical Probability:
P(rolling a 2) = 16.7%
P(rolling a 5) = 16.7%
P(rolling 2 or 3) = 33.4%
P(greater than 4) = 33.4%
P(3 or less) = 50.1%
Experimental Probability:
P(rolling a 2) = 20%
P(rolling a 5) = 6%
P(rolling 2 or 3) = 36%
P(greater than 4) = 24%
P(3 or less) = 54%
Explanation:
Theoretical probability can be calculated based on the idea that each of the six numbers on the die has an equal chance of being rolled and all numbers' probabilities total to 100%. Experimental probability is based on the outcomes of your experiment (rolling the dice yourself).
When finding the probability of rolling a number or another number (for example, rolling a 2 or 3), just add the probabilities together (You rolled 2 ten times and 3 eight times, so the experimental probability of rolling a 2 or 3 is 18/50 = 36%)

Given the first term and common ratio: Find the 10th Term. The first term is equal to 1 and the common ratio is
equal to -2.
Answer:
-512
Step-by-step explanation:
The appropriate general formula for a geometric series is a(n) = a(1)*r^(n - 1).
In this problem the first term, a(1) = 1, and the common ratio is r = -2. The pertinent geometric series is thus:
a(n) = (-2)^(n - 1), and the 10th term is a(10) + (-2)^(10 - 1) = -512 = a(10)

A square pyramid has a base length of 4 inches. The height of each triangular face is 12 inches. What is the surface area of the pyramid?
Answer:
The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].
Step-by-step explanation:
Base length of the pyramid = 4 inches
Area of the base = [tex]length^{2}[/tex]
= [tex]4^{2}[/tex]
= 16
Area of its base = 16 [tex]inches^{2}[/tex]
Area of one of its triangular surface = [tex]\frac{1}{2}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 4 x 12
= 2 x 12
= 24 [tex]inches^{2}[/tex]
Area of all its four triangular surfaces = 4 x 24
= 96 [tex]inches^{2}[/tex]
surface area of the pyramid = sum of areas of all its surfaces
= 16 + 96
= 112 [tex]inches^{2}[/tex]
The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].
