Dylan opened a credit card account with $575.00 of available credit. Now that he has made some purchases, Dylan's account only has $408.25 of available credit. What is the percentage decrease of the amount of available credit in Dylan's account?
Answer:
Dylan's credit card account has decreased by 29%.
Step-by-step explanation:
You first have to subtract:
$575.00 - $408.25 = $166.75.
You then have to divide the amount decreased by the total amount.
$166.75 / $575.00 = 0.29 = 29%
29% is the amount decreased in the credit card account.
Do the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the table.
x= 1 2 5 10
y= 6 12 30 60
a. direct variation y=1/6x
b. inverse variation xy=6
c. direct variation y=6x
d. inverse variation xy=1/6
c. y=6x direct variation
Answer:
the table represent a direct variation
Step-by-step explanation:
as when x=1
y=2
and
x=10
y=60
Answer:
y = 6x direct variation
Step-by-step explanation:
Remember that direct variation is y = kx and inverse variation is y = k/x where k is a constant
x= 1 2 5 10
y= 6 12 30 60
First look at direct y = kx solving for k y/x =k
y/x from the table is 6/1 =6 12/2 = 6 30/5 =6 60/10 =6 so k=6
This is a direct variation with k=6
y = 6x

Find the value of x.
a
x = 104
b
x = 72.5
c
x = 166
d
x = 93.5
Answer:
x=104
Step-by-step explanation:
Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)
10.5 = 1/2( x-83)
Multiply each side by 2
2* 10.5 = 2*1/2( x-83)
21 = x-83
Add 83 to each side
21+83 = x-83+83
104 =x

A newsletter publisher believes that less than 49% of their readers own a laptop. For marketing purposes, a potential advertiser wants to confirm this claim. After performing a test at the 0.10 level of significance, the advertiser decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim
Answer:
The answer is "At the 0,10 level, there should be enough proof that the percentage is below 49%"
Step-by-step explanation:
Null and alternative hypothesis:
[tex]H_0 :P \geq 0.49\\\\H_1:P<0.49 \ \ (\text{Left tailed test})\\\\[/tex]
Significance level: [tex]\alpha = 0.10[/tex]
It is decided that the null hypothesis at the defined meaning level is rejected.

Step-by-step explanation:
Given sin e
; and angle 0 is in Quadrant III, what is the exact value of cos 0 in
simplest form? Simplify all radicals if needed.
Answer:
[tex]\cos \theta = -\frac{\sqrt{5}}{3}[/tex]
Step-by-step explanation:
Draw a right triangle with angle [tex]\theta[/tex]. In all right triangles, the sine of an angle is equal to its opposite side divide by the hypotenuse of the triangle. Therefore, label the side opposite to [tex]\theta[/tex] as 2 and the hypotenuse (longest side) of the right triangle as 3.
To find the last side, use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex], where [tex]c[/tex] is the hypotenuse of the triangle.
Solving for [tex]a[/tex]:
[tex]a^2+2^2=3^2,\\a^2+4=9,\\a^2=5,\\a=\pm\sqrt{5}\implies \sqrt{5}[/tex]
In all right triangles, the cosine of an angle is equal to its adjacent side divided by the hypotenuse. However, the cosine of all angles in Quadrant III are negative. Therefore, the desired answer is [tex]\cos \theta=\boxed{-\frac{\sqrt{5}}{3}}[/tex].
Verify:
[tex]\sin \theta =-\frac{2}{3},\\\\\theta=\arcsin(-\frac{2}{3}}),\\\\\cos(\arcsin(-\frac{2}{3}}))=-\frac{\sqrt{5}}{3}\checkmark[/tex]

What is 15/5 simplified?
Answer:
3
Step-by-step explanation:
fractions are division, so if you divide the numerator by the denominator you'll always get the mixed number / whole number
so 3/4 is equal to 3 divided by 4

How many questions were on Victoria test
Measurement question please show work thank you
Answers:
b) 92100 decimeters
c) 6650 decaliters
=====================================================
Work Shown for part b)
1 decameter = 10 meters
1 decimeter = 1/10 of a meter
10 decimeters = 1 meter .... multiply both sides by 10
100 decimeters = 10 meters ... multiply both sides by 10
100 decimeter = 1 decameter
921*(100 decimeter) = 921*(1 decameter)
92100 decimeters = 921 decameters
-------------------
Work Shown for part c)
We could follow the same idea as part b). I'm going to use another approach as shown in the diagram below. This conversion method is known as the railroad tracks method in some math textbooks.
Each column represents two things that are equivalent to one another. For example, 1 kiloliter is the same as 1000 liters. So each column, when you divide top over bottom, represents the value 1.
Notice the unit cancelations as shown by the color coding. The goal is to have every unit cancel except for the decaliters unit which is what we want to end up with ultimately.
Once you have the railroad tracks set up, you multiply straight across.
Along the top, we have 66.5*1000*1 = 66500
Along the bottom we have 1*10 = 10
Divide those results: 66500/10 = 6650
So 66.5 kiloliters converts to 6650 decaliters
Answer:
1) 92100 dm
2) 6650 decalitres

Find the nth term of the quadratic sequence
Answer:
x^2
Step-by-step explanation:
all the numbers are square roots so n square is the nth term.
2^2= 4
3^2=9
4^2=16
5^2=25
6^2=36
Answer:
[tex] {n}^{2} [/tex]
Step-by-step explanation:
Drawing number into triangular dot pattern and making a square (with same numbers of dots in rows and columns) will give a square number. Similarly, 16 = 42 = 32 + (3 + 3 + 1), 25 = 52 = 42 + (4 + 4 + 1) and so on.
Can someone help me plzzzz
Answer:
279 feet
Step-by-step explanation:
To find x, we solve using the Trigonometric function of Tangent
tan θ = Opposite/ Adjacent
θ = 64°
Length of the shadow = Adjacent = 136 feet
Height of the building = Opposite = h
Hence,
tan 64 = h/136 feet
Cross Multiply
h = tan 64 × 136 feet
h = 278.84132245 feet
Approximately, h to the nearest foot ≈ 279 feet
Therefore, the height of the building = 279 feet

The piecewise defined function f(x) is graphed below. What is the value of f(5)?
================================================
Explanation:
Draw a vertical line through 5 on the x axis. This represents the equation x = 5. Notice that we intersect the blue line at (5,-1) which tells us that f(5) = -1. There's a closed point here, meaning that the point is included. This is in contrast to the open hole at (5,3) which is not part of the function. So be careful not to say that f(5) = 3 because that's not the case.
Answer:
i think it's f(5) - a wild guess
Step-by-step explanation:
