Answer:
$2.40
Step-by-step explanation:
Take the price of each item and divide by ten to find the cost of 1/10:
3 divided by 10 = .3
5 divided by 10 = .5
Then multiply by the amount he is purchasing:
.3 x 3 = .9
.5 x 3 = 1.5
Add the prices together for a total:
.9 + 1.5 = 2.4
Simplify: 327

David correctly factored the expression m^2 - ono
12m - 64.
Which expression did he write?
(1) (m-8)(m - 8) (3) (m - 16)(m + 4)
(2) (m - 8)(m + 8) (4) (m +16)(m - 4)
Explain why
Answer:
the correct option is number (3). It corresponds with the expression David factorised.
Step-by-step explanation:
David correctly factored the expression m² - 12m + 64, we want to check which one of the options he wrote.
(1) (m - 8)(m - 8) = (m - 8)²
= m² - 16m + 64
NOT THIS
(2) (m - 8)(m + 8) = m² - 8²
= m² - 64
NOT THIS
(3) (m - 16)(m + 4) = m² + 4m - 16m - 64
= m² - 12m - 64
THIS IS THE CORRECT OPTION AS IT CORRESPONDS WITH THE EXPRESSION DAVID FACTORISED
(4) (m + 16)(m - 4) = m² - 4m + 16m - 64
= m² + 12m - 64
NOT THIS
the total amount of fiber (in grams) in a package containing x apples and y oranges is given by the equation 5x + 10y = 110. is it possible for the package to contain 15 apples? EXPLAIN
Answer:
Step-by-step explanation:
The y intercept is the value of y when x = 0. Similarly, the x intercept is the value of x when y = 0. To find each of these, we separate the equation as shown in the attached image. After solving for x and y, we find that the y intercept is 11 and the x intercept is 22. For part e, we substitute 15 in for x. So instead of putting x in the equation, we will put 15 and solve for y. After solving, we see that y will equal 3.5. However, since we cannot have a "half apple" in the package, we see that it is not possible to have 15 apples in the package.
Find the point on the terminal side of θ = negative three pi divided by four that has an x coordinate of -1. Show your work for full credit.
Answer:
(-1,-1)
Step-by-step explanation:
x = rcos(theta)
-1 = r cos(-3pi/4)
-1 = r(-sqrt(2)/2)
r = sqrt(2)
y = rsin(theta)
y = sqrt(2)sin(-3pi/4)
y = -1
(-1,-1)
can someone explain the Pythagorean Theorem to me
Answer:
The Pythagorean theorem deals with the lengths of the sides of a right triangle. ... The sum of the squares of the lengths of the legs of a right triangle ('a' and 'b' in the triangle shown below) is equal to the square of the length of the hypotenuse ('c').

Log(2) 256 = 8, write the exponential form
Answer:
28=256
Convert the exponential equation to a logarithmic equation using the logarithm base (2)
of the right side (256) equals the exponent (8)
.
log2(256)=8
Step-by-step explanation:
In exponential form, the base (2 in this case) is raised to the exponent (8), resulting in the value on the right side of the equation (256).
In the given equation, we have:
Log₂ 256 = 8
This equation can be read as "the logarithm base 2 of 256 equals 8."
To express it in exponential form, we need to understand that logarithms and exponentiation are inverse operations.
In other words, if we have a logarithmic equation like this, we can convert it into an exponential equation by applying the exponentiation operation.
In this case, the logarithm is base 2, so the exponential form will have a base of 2 as well.
The exponent will be the value equal to the logarithm result. Thus, we can write the exponential form as:
2⁸ = 256
In this equation, 2 is the base and 8 is the exponent.
By raising 2 to the power of 8, we get the value of 256, which is equivalent to the logarithmic expression Log₂ 256 = 8.
Hence in exponential form, the base (2 in this case) is raised to the exponent (8), resulting in the value on the right side of the equation (256).

B. Lance is 39 years old. Ted is 22 years old.
Rosalinda is 45 years old. How old is Erik if the
mean age of the four friends is 33.5?
Answer:
28 years
Step-by-step explanation:
Sum of the years of Lance , Ted, Rosalinda = 39 + 22 +45 = 106 year
Sum of the years of Lance , Ted, Rosalinda & Erik = 33.5*4 = 134.0 year
Age of Erik = 134 - 106 = 28 years

The area of a wetland is 10,000 acres. A biologist predicts that the area of the wetland will change according to the equation y equals 10000 left-parenthesis 0.65 right-parenthesis Superscript x Baseline, where y is the area of the wetland after x years. Based on the biologist's prediction, what will the area of the wetland be in 2 years?
Answer:
4,225 acresStep-by-step explanation:
If a biologist predicts that the area of the wetland will change according to the equation [tex]y = 10,000(0.65)^{x}[/tex] where;
y is the area of the wetland after x years
In order to determine the area of the wetland in 2 years based on the biologist prediction, we will substitute the value of x = 2 into the modeled equation as shown;
[tex]y = 10,000(0.65)^{2}\\y = 10,000 * 0.4225\\y = 4225[/tex]
The area of the wetland in 2 years based on the biologist prediction will be 4225 acres
