Find the LCM of 91, 143 and 169
Answer:
13013
Step-by-step explanation:
Express each number in terms of the product of prime numbers.
91 = 7 × 13
143 = 11 × 13
169 = 13 × 13
Now consider the maximum number of times each factor occurs for each number.
The factor 7 occurs once
The factor 11 occurs once
The factor 13 is repeated twice ( maximum number of times for 1 number )
Thus LCM = 7 × 11 × 13 × 13 = 13013
91 = 7×13
143 = 11×13
169 = 13²
LCM = 7×11×13² = 77×169 = 13013

Claire is buying a new bicycle for $295. If the
sales tax is 4.75%, what will she pay in total?
Answer:
$309.01
Step-by-step explanation:
To calculate tax, you need to turn the percent to a decimal. This is done by moving the decimal point two spaces to the left, adding zeros and needed.
4.75% = 0.0475
Now take the price of the bike, 295, and multiply it by 0.0475.
295 x 0.0475 = 14.0125
All you need are the first two numbers after the decimal point since you are dealing with money.
Add the product, 14.01, to the price of the bike, 295, and you have your answer.
$309.01

find the next 3 terms in the sequence:30,22,14,6
A.-3,-12,-21
B.-1,-8,-15
C.-1,-2,3
D.-2,-10,-18
Answer:
D
Step-by-step explanation:
Note the difference between consecutive terms is constant, that is
22 - 30 = - 8
14 - 22 = - 8
6 - 14 = - 8
To obtain a term in the sequence subtract 8 from the previous term, thus
6 - 8 = - 2
- 2 - 8 = - 10
- 10 - 8 = - 18
The next 3 terms in the sequence are - 2, - 10, - 18 → D

I’ve been stuck on this question for a while someone please help me
A) Equation: f = 2.75p
B) 38.5 cups of flour are needed to make 14 pound cakes
Step-by-step explanation:
A)
The table shows the following data:
Pound cakes, p 3 6 9
Cups of flour, f 8.25 16.5 24.75
From the table, we notice that the increase in cups of flour needed per increase in pound cakes is:
[tex]m=\frac{16.5-8.25}{6-3}=\frac{8.25}{3}=2.75[/tex]
This means that for each additional pound cake, we need 8.25 more cups of flour.
This is a direct relationship between the two variables, therefore we can write their relationship using the equation:
[tex]f=2.75 p[/tex]
B)
Now we can complete the table.
We have to found how many cups of flour are needed when the number of pound cakes is
p = 14
In order to do that, we use the equation found in part A):
f = 2.75p
And substituting p = 14 into the equation, we find
f = (2.75)(14)= 38.5
Which means that 38.5 cups of flour are needed to make 14 pound cakes.

Solve for x.
6.5 cm
8 cm
7.5 cm
7.2 cm
Answer:
7.2 cm
Step-by-step explanation:
For the similar triangles, the ratio of the length of the bottom side to the right side is the same:
bottom/right = (x cm)/(6 cm) = (12 cm)/(10 cm)
x cm = (6 cm)(12/10) = 7.2 cm
_____
Technically, x = 7.2, not 7.2 cm.
At a given time of day , the ratio of the height of an object to the length of its shadow is the same for all objects. If a 4-ft stick in the ground casts a shadow of 2.4 ft, find the height of a tree that casts of shadow that is 23.04ft.
Answer:
38.40 ft
Step-by-step explanation:
The problem statement tells you the proportion is ...
height/shadow = (4 ft)/(2.4 ft) = (tree height)/(23.04 ft)
Multiplying by 23.04 ft, we find ...
tree height = (23.04 ft)(4/2.4) = 38.40 ft
The height of the tree is 38.40 ft.
Given a function described as equation y=3x+4, what is y when x is 1,2 and 3?
Answer:
x=1 y= 7
x=2 y= 10
x=3 y= 13
Step-by-step explanation:
y=3x+4
y=3(1)+4
=7
y=3(2)+4
=-10
y=3(3)+4
=13
For this case we have the following equation:
[tex]y = 3x + 4[/tex]
We must find the value of the variable y when the variable x takes certain values.
For [tex]x = 1:[/tex]
[tex]y = 3 (1) +4\\y = 3 + 4\\y = 7[/tex]
For [tex]x = 2:[/tex]
[tex]y = 3 (2) +4\\y = 6 + 4\\y = 10[/tex]
For [tex]x = 3:[/tex]
[tex]y = 3 (3) +4\\y = 9 + 4\\y = 13[/tex]
Thus, the values of y are 7,10,13 respectively.
Answer:
[tex]y = 7\\y = 10\\y = 13[/tex]

Suppose θ is an angle in the standard position whose terminal side is in Quadrant IV and cotθ= -2/17 . Find the exact values of the five remaining trigonometric functions of θ.
Final answer:
Given an angle θ in Quadrant IV with cotθ = -2/17, a right triangle is formed. Using the Pythagorean theorem, the hypotenuse is calculated, and the five additional trigonometric functions of θ are determined with appropriate signs for Quadrant IV.
Explanation:
If θ is an angle in the standard position whose terminal side is in Quadrant IV and cotθ = -2/17, we can find the five remaining trigonometric functions.
The cotangent of an angle θ, which is the reciprocal of the tangent, tells us that the tangent of θ is -17/2. Since the angle is in Quadrant IV, where cosine and secant are positive but sine and cosecant are negative, we can form a right triangle within the coordinate plane to represent this scenario. In this triangle, the adjacent side (x) to the angle θ will be positive, and the opposite side (y) will be negative.
Using the Pythagorean theorem, if we assume the adjacent side to be 17 (because cotθ = adjacent/opposite), and the opposite side to be -2 (to make cotθ = 17/(-2) = -2/17), the hypotenuse (r) can be calculated as:
√(17² + (-2)²) = √(289 + 4) = √293
Now we can find the other five trigonometric functions:
Sinθ = opposite/hypotenuse = -2/√293Cosθ = adjacent/hypotenuse = 17/√293Tanθ = opposite/adjacent = -2/17 (which was given)Cscθ = hypotenuse/opposite = -√293/2Secθ = hypotenuse/adjacent = √293/17The signs of these values are consistent with the properties of trigonometric functions in the fourth quadrant.
Dave drove 55 mph for part of the trip and 60mph for the rest. The 245 mile trip took him 4 hours 12 minutes. How long did the 2nd part of the trip take? How far did he drive during the 2nd part of his trip?
Answer:
Dave drove 168 miles during the 2nd part of the trip
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Speed of Dave for part of the trip = 55 mph
Speed of Dave the rest of the trip = 60 mph
Total time of the round trip = 4 hours 12 minutes
Total distance of the trip = 245 miles
2. How far did Dave drive during the 2nd part of his trip?
Let's recall that the formula of speed is:
Speed = Distance/Time, therefore Distance = Speed * Time
x = Time of part of the trip
4 hours 12 minutes - x = Time of the rest of the trip
4.2 hours - x = Time of the rest of the trip
Now, we can write solve for x, this way:
55 * x + 60 (4.2 - x) = 245
55x + 252 - 60x = 245
-5x = 245 - 252
-5x = -7
x = -7/-5 = 7/5 = 1.4 ⇒ 4.2 - x = 2.8
1st part of the trip = 55 * 1.4 = 77 miles
2nd part of the trip = 2.8 * 60 = 168 miles
Dave drove 168 miles during the 2nd part of the trip and 77 miles during the 1st part

What is the vertex of the function: f(x) = x² + 12x ? Please explain.
(–6, 0)
(-6, -36)
(6, 0)
(6, –36)
The vertex of the function is (-6,-36).
Step-by-step explanation:
f(x) = x²+ 12x
From the above function, we can find the x- coordinate of the vertex as,
x = -b/2a
Here a = 1, b = 12
Plugin the values as,
x = -12 /(2×1) = -6
Now plug in the x value in the above function, we will get y as,
f(x) = y = x² + 12x = (-6)² + 12(-6)
= 36-72 = -36
So the vertex is (-6, -36).
