7) The sum of the angle measures of a
quadrilateral is 360°. Find the value of x.
24
2
Answer:
x=120°
Step-by-step explanation:
X+X+1/2X+1/2X=360
combine all like variables
X+X=2X
1/2X+1/2X=X
2X+X=3X
3X=360
isolate x by dividing both sides by 3
360÷3=120
X=120
Which method used to determine numbers of bacteria in a sample involves the preparation of a series of dilutions of the sample in sterile water, adding measured volumes of each dilution to melted nutrient agar plates, making pour plates, incubating, counting colonies, and multiplying colony counts by dilution factors to determine the number of bacteria in the sample
Answer:To obtain a readily counted and statistically accurate number of bacteria. When performing a standard plate count using the pour plate method, the dilutions are first made, and then measured aliquots of each dilution are cultured.
Step-by-step explanation:
The dimension of a cube are 3 x cm, 6xm 7xm. Then find the volume of the cube.
Answer:ce 6x^2=216
Step-by-step explanation:
since this is a cube, the length, width, and height are the same, so they can all be replaced with one variable, x. When simplified, the equation reads 6x^2=216

What expression is equivalent to 4 to the power of 4 times 4 to the power of -9
answer the equation please <33
Answer: Total cost = 4m
Step-by-step explanation:
Each meal is $4, so the total would be the number of meals times $4/meal: Total = 4m
Answer:
dₙ = (m-1)*4
Step-by-step explanation:
d1: initial dollar d1=0
dₙ = (m-1)*4
d₁ = (1-1)*4 = 0
d₂ = (2-1)*4 = 4
d₃ = (3-1)*4 = 8
1. How much simple interest is earned on $3,000 in 9 years at an interest rate of
4.5%?
Can anyone help please? This is due tomorrow and I don’t understand this
Answer:
I = $1,215
Step-by-step explanation:
Principal (P ) = $3,000
interest rate (R ) = 4.5% or 0.045
time (in years) ( t )= 9
Use the simple interest formula:
I = P × r × t
I = $3,000 × 0.045 × 9
I = $1,215
Therefore, the simple interest earned on a $3,000 investment after 9 years is $1,215.

Let fat be the explanatory variable and calories be the response variable; which scenario best describes ŷ = 121 + 1.42x?
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
The amount of calories in a cheeseburger increases by 121 for every one gram of fat. The calorie amount estimated by this model is 1.42 if there are zero grams of fat.
The amount of fat in a cheeseburger increases by 121 grams for every one calorie.
The fat amount estimated by this model is 1.42 grams if there are zero calories.
The amount of fat in a cheeseburger increases by 1.42 grams for every one calorie.
The fat amount estimated by this model is 121 grams if there are zero calories.
The amount of calories in a cheeseburger increases by 1.42 when there are zero grams of fat.
The calorie amount estimated by this model is 121 if there is one gram of fat.
Using linear function concepts, it is found that the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which represents by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The explanatory variable fat is the input.The response variable calories is the output.The equation is:
[tex]y = 121 + 1.42x[/tex]
The slope is of 1.42, which means that the amount of calories increases by 1.42 when the amount of fat increases by 1 gram.The y-intercept is of 121, which means that if there are 0 grams of fat, there will be 121 calories.Thus, the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.

Step-by-step explanation:
Mrs. Blake needs to hire a babysitter. Kelsey charges $6 per hour plus a $5 fee. Lauren charges $4 per hour, plus a $10 fee. Mrs. Blake set up this equation to figure out for what amount of time both babysitters charge the same.
6h + 5 = 4h + 10
What is the correct sequence of steps to solve Mrs. Blake’s equation?
A. Subtract 6h from both sides. Subtract 5 from both sides. Divide each side by –2.
B. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 2.
C. Subtract 4h from both sides. Add 5 to both sides. Divide each side by 2.
D. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 6.

Determine the equation of the line.
Answer:
y = 5x -10
Step-by-step explanation:
The y-intercept is -10, as in, the line on the y-axis is at -10
The slope is 5, as in, the line is moving up 5 and right 1. So it should be 5/1x but you don't need the 1. You could use it, but you don't need to. Here's what it would look like if you did use it:
y = 5/1x - 10

Write a quadratic function [tex]f[/tex] whose only zero is 12.
Answer:
f(x) = (x - 12)²Step-by-step explanation:
If a quadratic function has only one zero, then it has multiplicity of two as it is a second degree polynomial and should have two roots. Since one root is a real number, the second root is also a real number being same as the first number.
The function could be:
f(x) = (x - 12)²We know the rule for single zero of quadratic equations
[tex]\\ \sf\longmapsto g(x)=(x-n)^2[/tex]
[tex]\\ \sf\longmapsto g(x)=(x-12)^2[/tex]
