Lucy went to the pet store to buy 17 fish for her aquarium. She bought Fancy Goldfish for $13.49 each and Plecos for $3.25 each. She spent a total of $198.61. How many of each kind of fish did Lucy buy?
Answers
Step-by-step explanation:
let gold fish= X
let Plecos fish= Y
X +Y = 17................(I)
13.49X + 3.25Y =198.61........(II)
solve simuteniously to get
X = 14
Y = 3.....therefore
she bought 14 gold fish and 3 plecos fish
3x + 5 > 16
x is an integer.
Find the smallest value of x.
Answers
Answer:
4
Step-by-step explanation:
3x + 5 > 16
3x > 16 - 5
3x > 11
x > 11 / 3
x > 3.6666...
The smallest value would be 4.
Answer:
4
Step-by-step explanation:
Given
3x + 5 > 16 ( subtract 5 from both sides )
3x > 11 ( divide both sides by 3 )
x > [tex]\frac{11}{3}[/tex] , that is
x > 3 [tex]\frac{2}{3}[/tex]
If x is an integer then the smallest value of x is 4
Find the length of the missing side.
Answers
Answer: i think 80 not sure tho i failed my last test
Step-by-step explanation:
Answer:
80 in
Step-by-step explanation:
Because this is a right triangle we can find the length of the missing side using the Pythagorean Theorem
Given the hypotenuse and one leg we do
[tex]c^2-b^2=a^2[/tex]
where c = hypotenuse and b = leg
[tex]82^2=6724\\18^2=324\\6724-324=6400\\\sqrt{6400} =80[/tex]
so we can conclude that the missing side length is equal to 80
What is the definition of a tangent in math
Answers
Answer:
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. ... The word "tangent" comes from the Latin tangere, "to touch".
Step-by-step explanation:
A straight line touching a curve at a single point without crossing it there is tangent.

How many solutions does this equation have? Explain.
a. -1 = x3; One solution because only -1 will satisfy the equation.
b. -1 = x2; No real solution because there is no real number that, when squared, produces -1.
c. 1= x?: Two solutions because the square root of 1 is positive 1 and negative 1.
d. 1=-x?: One solution because only -1 will satisfy the equation.

Find AC please, help is very much appreciated.
Answers
Answer:
AC ≈ 67.9
Step-by-step explanation:
15² = 9 (3x + 1 + 9)
225 = 9 (3x + 10)
225 = 27x + 90
135 = 27x
x ≈ 19.29
AC = (3x + 1 + 9)
AC = 3 (19.2857...) + 1 + 9
AC = 57.857... + 1 + 9
AC = 57.857... + 10
AC ≈ 67.9

The line y = mx + c passes through the points (-2, 1) and (4,4).
Write down a pair of simultaneous equations involving m and c.
Solve the simultaneous equations.
Answers
Answer:
Step-by-step explanation:
Insert x for -2 & 4 and y for 1 & 4
1=-2m+c, 4=4m+c
solve the equation, m=1/2, c=2
Answer:
y = 1/2m + 2
Step-by-step explanation:
1 = -2m + c (1)
4 = 4m + c (2)
2 = -4m + 2c (1*)
(1*) + (2) = 6 = 3c
c = 2
y = mx + 2
4 = 4m + 2
2 = 4m
m = 1/2
so y = 1/2m + 2
A teacher is planning a class trip to the aquarium. The aquarium requires 2 chaperones for every 15 students. The teacher plans accordingly and orders a total of 85 tickets. How many tickets are for chaperones, and how many are for students?
Answers
Answer:
75 student tickets and 10 chaperone tickets
Step-by-step explanation:
First find out how many groups there are total by dividing 85 by 1 group total of 17 (15 students 2 chaperones).
85 / 17 = 5
Since you now know there are five groups of 15 students and 2 chaperones all you have to do is multiply 5 time 15 students and 5 times 2 chaperones.
15 x 5 = 75 for students
5 x 2 = 10 for chaperones

What is the degree measure of ABC given that A=25 & C=135?
Answers
Answer:
m∠ABC = 110°
Step-by-step explanation:
By the property of exterior angle of a triangle,
"Exterior angle of a triangle is equal to the sum of two opposite interior angles"
m∠BAC + m∠ABC = 135°
25° + m∠ABC = 135°
m∠ABC = 135° - 25°
= 110°
Therefore, measure of angle ABC is 110°.
The side of a hill makes a 12° with the horizontal. A wire is to be run from the top of a 175 foot tower on the top of the hill to a stake 120 ft down the hillside from the base of the tower. What length of wire is needed
Answers
Answer:
231.9ft
Step-by-step explanation:
We would be solving this problem by using the cosine rule.
The length = (pq)² + (qr)² -2 * pq * qr * cos102⁰
= 120² + 175² - 2*120*175 (-0.2079)
= 14400 + 30625 + 8731.8
= 53756.8
Length² = 53756.8
We take the square root of both sides
Length = √53756.8
Length = 231.89 feet
This is the length of the wire that is needed.
Thank you
