The school cafeteria sells apples for $0.25 and pears for $1.15. On Thursday they sold 9 pieces of fruit earning a total of $4.95. How many of each item did they sell?
9514 1404 393
Answer:
6 apples3 pearsStep-by-step explanation:
Let p represent the number of pears sold. Then 9-p is the number of apples sold. The total revenue was ...
0.25(9 -p) + 1.15p = 4.95
0.90p +2.25 = 4.95 . . . . . . collect terms
0.90p = 2.70 . . . . . . . . . . subtract 2.25
p = 3 . . . . . . . . . . . . . . . divide by 0.90
They sold 3 pears and 6 apples on Thursday.
The area of a rectangle is 52 in.² if the length is two times the width find the dimensions of the rectangle round off your answers to the nearest hundredth
Answer:
L = 10.20
w = 5.51 Do the doubling before the rounding. The zero is needed in the length.
Step-by-step explanation:
Area = 52 in^2
Area = L * w
L = 2*w
Area = 2w * w = 52
2w^2 = 52 Divide by 2
w^2 = 26 Take the square root of both sides
sqrt(w^2) = sqrt(26)
w = 5.5099
L = 10.198

If f(x) = x³ - 2, find f(3).
Answer:
25
Step-by-step explanation:
First you have to understand what f(3) means.
f(x) = x^3 - 2
f(3) means that wherever you see and x, you put in a 3.
f(3) = 3^3 - 2
f(3) = 3*3*3 - 2
f(3) = 27 - 2
f(3) = 25

WILL MARK BRAINIEST!!!
The perpendicular bisector on a line segment AB is in the attached image.
Given:
Segment ABTo Construct:
The perpendicular bisector to segment AB.Solution:
A segment is a line with two ends with a specific length.
A perpendicular bisector is a line intersecting the other line segment into two equal lengtsh at an angle of 90 degrees.
Steps of construction:
With help of unmarked straightedge draw segment,AB.Open the compass more than half of the length of the AB segment and from point A, draw an arc above and below AB.Now, with that same compass from B draw arcs cutting the previous arcs made above and below the AB label them C and D.Draw a straight line from C to D which will be the perpendiular bisector of segemnt AB.The perpendicular bisector to a segment AB is in the image attached.

#learnwithbrainly
Answer:
Step-by-step explanation:
To create a perpendicular bisector, you need a compass, a straightedge, and a pencil. As well as the line segment AB drew down.
1> You start by opening the compass and stretching it to a width greater than half the length of AB.
2> Then you simply place one point of the compass on the line segments A. From here, you move the compass and draw arcs above and below the line AB.
3> Without moving the compass measure, remove it from point A and place it onto point B. You basically repeat step 2 by drawing arcs above and below the line again.
4> If you've done it right, the arcs should be in the middle, X and Y, and using a straightedge/ruler you draw a line that goes vertically through where they connect.
and that should be your perpendicular bisector using segment AB.

Condense to a single logarithm: ln x +ln y − z
Question 12 options:
A) ln (x + y – z )
B) ln xy∕z
C) (ln x)(ln y∕z)
D) ln xy∕ ln z
Answer:
It is B
Step-by-step explanation:

from law of logarithms:
[tex]{ \bf{ ln(a) + ln(b) = ln(ab) }} \\ and \\ { \bf{ ln(a) - ln(b) = ln( \frac{a}{b} ) }}[/tex]
so, in the question:
[tex] ln(x) + ln(y) - ln(z) \\ \\ = \{ ln(xy) - ln(z) \} \\ \\ = ln( \frac{xy}{z} ) [/tex]
The required logarithmic expression is ln(xy/z). Option B is correct.
Given that
To simplify ln x + ln y + ln z
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
A logarithmic function can be defined as the function inverse of the exponential function is a logarithmic function.
In the question, an algebraic expression of the log function is given a simplified form of the expression to be determined using the logarithmic property.
Simplification,
= ln x +ln y + ln z
Since log A + log B = log(A.B)
and log A - logB = log(A/B)
From above properties
= ln (x . y) - ln z
= ln [(x. y )/z]
Thus, the required logarithmic expression is ln(xy/z). Option B is correct.
