to find the dimension I would get 3.6/4.5=x/70 amd u get 3.6*70=4.5x and u get 252=4.5x and x=56
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the width of logo printed on canvas = x inches
Dimensions are in proportion
[tex]\frac{70}{x}=\frac{3.6}{4.5}\\[/tex]
Cross multiply
70 * 4.5 = x * 3.6
x * 3.6 = 315
[tex]x=\frac{315}{3.6}\\\\=\frac{3150}{36}\\\\x=87.5inches[/tex]
What is the APPROXIMATE circumference of a circle with a radius of 9 inches? Use 3.14 for π. 28.3 in. 56.5 in. 254.34 in. 113.0 in.
Answer:
56.52 in
Step-by-step explanation:
Circumference Formula: C = 2πr
Since we are given radius r = 9, simply plug it into the formula:
C = 2π(9)
C = 18π
C = 56.5487
Answer:
56.5
Step-by-step explanation:
The circumference is the product of the diameter and PI
P = (9+9)*π = 18*3.14=56.52
make h the subject of the formula A=(1/2)ah-(1/2)bh
Answer:
h = A ÷ ½(a - b)
Step-by-step explanation:
A = ½ah - ½bh
A = ½h( a - b)
Divide both sides by the coefficients of h
A ÷ ½(a - b) = h

Determining Key Aspects of a Quadratic Function
Use the drop-down menus to describe the key aspects of the function f(x) = -X2 - 2x - 1.
The vertex is the
The function is increasing
The function is decreasing
The domain of the function is hs
The range of the function is
Answer:
Step-by-step explanation:
The vertex can be located most easily by completing the square of
f(x) = -X^2 - 2x - 1 (which is equivalent to -(x^2 + 2x + 1). The latter expression can be rewritten as -(x + 1)^2, which indicates that the x-coordinate of the vertex is -1. The corresponding y-value is 0. Vertex is at (-1, 0).
The function is increasing for x < -1 and decreasing for x > -1.
The domain of the function is "all real numbers."
The range is (-infinity, 0)

Yeah, you got the answer right.
Step-by-step explanation:
For f(x) = 4x +1 and g(x) = x2 - 5, find (f-8)(x).
Answer:
(f-g)(x) = -x² +4x +6
Step-by-step explanation:
We assume you want to find (f -g)(x).
[tex](f-g)(x)=f(x)-g(x)=(4x+1)-(x^2-5)\\\\\boxed{(f-g)(x)=-x^2+4x+6}[/tex]
8÷2 2/9 −2 11/15 I need help and this is a whole equation I need this ASAP
Answer: (1 and 22/45)
Step-by-step explanation:
I guess that we are working with mixed numbers here, and we have the equation:
(8÷2 2/9) − (2 11/15)
first we solve: 8÷2 = 4.
Now, we can write this as:
(4 + 2/9) - (2 + 11/15)
(4 - 2) + (2/9 - 11/15)
now, 9*5 = 45
15*3 = 45
then we can write the right side as: 2/9 - 11/5 = 10/45 - 33/45 = -23/45
2 - 23/45
But in mixed numbers we also need to work with a positive rational, then we have:
2 - 23/45 = 1 + 1 -23/45 = 1 + 45/45 - 23/45 = 1 + 22/45
then the solution is:
(1 and 22/45)
Which point is a reflection of T(-6.5, 1) across the x-axis and the y-axis? A. point U B. point V C. point W D. point X
Hey there! :)
Answer:
Point V.
Step-by-step explanation:
Given the coordinates of T at (-6.5, 1), U represents T before any reflections. (Helps to visualize this better)
Reflecting across the x-axis results in the sign of the y-coordinate changed. Point T after this reflection becomes (-6.5, -1).
Finally, reflecting across the y-axis will change the sign for the x-coordinate.
(-6.5, -1) becomes (6.5, 1). This is represented by point V.

How can Ari simplify the following expression? StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1 Over a minus 3 EndFraction
Answer:
[tex]-\frac{8}{3}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5}{-3} - \frac{4}{2} + \frac{1}{-3}[/tex]
Required
Simpify
The very first step is to take LCM of the given expression
[tex]\frac{-10 -4 - 2}{6}[/tex]
Perform arithmetic operations o the numerator
[tex]-\frac{16}{6}[/tex]
Divide the numerator and denominator by 2
[tex]-\frac{16/2}{6/2}[/tex]
[tex]-\frac{8}{3}[/tex]
The expression can't be further simplified;
Hence, [tex]\frac{5}{-3} - \frac{4}{2} + \frac{1}{-3}[/tex] = [tex]-\frac{8}{3}[/tex]
what is the Lcd of fra tions 1_3 and 11 _15
it's 15, since it is divisible by both 15 (15 x 1) and 3 (3 x 5)
Answer:
15
Step-by-step explanation:
Well to find the least common denominator of [tex]\frac{1}{3}[/tex] and [tex]\frac{11}{15}[/tex].
We have to see if 11/15 can be reduced, and by looking at the fraction it can’t be reduced.
So we just have to make 1/3 fraction have the same demimitator as 11/15.
So we just multiply it by 3 to get 15 go the LCD is 15.
Lisa drew three circles to form a figure. The areas of the circles were in the
ratio 1:4:16. She then shaded some parts of the figure as shown.
What fraction of the figure was shaded?
Answer:
Fraction of the figure shaded = [tex]\frac{13}{16}[/tex]
Step-by-step explanation:
Ratio of the areas of the given circles are 1 : 4 : 16
Then the radii of the circles will be in the ratio = [tex]\sqrt{1}:\sqrt{4}:\sqrt{16}[/tex]
= 1 : 2 : 4
If the radius of the smallest circle = x units
Then the radius of the middle circle = 2x units
and the radius of the largest circle = 4x units
Area of the smallest circle = πx²
Area of the middle circle = π(2x)² = 4πx²
Area of the largest circle = π(4x)²= 16πx²
Area of the region which is not shaded in the middle circle = πx²(4 - 1)
= 3πx²
Therefore, area of the shaded region = Area of the largest circle - Area of the region which is not shaded
= 16πx² - 3πx²
= 13πx²
Fraction of the figure which is not shaded = [tex]\frac{\text{Area of the shaded region}}{\text{Area of the largest circle}}[/tex]
= [tex]\frac{13\pi x^{2} }{16\pi x^{2} }[/tex]
= [tex]\frac{13}{16}[/tex]
HELP ASAP!!!!!!!!!!!!!!!
Answer:
B) (x^2-2x)/(2x+6)
Step-by-step explanation:
When dividing fractions, it's just like multiplying the reciprocal of the second fraction : x/y divided by z/w = x/y * w/z.
We use that and we get (x-2)/(x+3) * x/2. we simplify and get x(x-2)/2(x+3). So Our answer is B
Using the unit circle, determine the value of cos(-150°).
Explanation:
The identity we'll use is cos(-x) = cos(x) for any value of x.
So cos(-150) = cos(150).
Then locate the angle 150 on the unit circle. The terminal point is [tex]\left(-\frac{\sqrt{3}}{2}, \frac{1}{2}\right)[/tex]
The x coordinate of this terminal point is the value of cos(150).
Answer:
Cos(-150°)=-√3/2
Step-by-step explanation:
-150° is found at the third quadrant so the cost value at third quadrant is negative
Cos(-150°)= -cos(30)=-cos(210)
Cos(-150°)=- (√3/2)
Cos(-150°)=-√3/2

Question
Shelly has 50 shortsin her closet. Shawnie her
Sister borrowed Some of
her shorts. Now shelly has
44 Shosts. How many
Shorts did Shawnie borrow.
A. 50-n = 44
B. 50 t n = 44
c. 50 n = 44
D.44 n =50
Answer:
A.50-n=44, 6 shorts borrowed
Step-by-step explanation:
If her sister borrowed n shorts, that means Shelly now has n less shorts. Since her amount of shorts is 50, then 50-n must equal how many shorts she has now, meaning 50-n=44. Solving the equation we get n=6. This means that her sister borrowed 6 shorts.
Answer:
A
Step-by-step explanation:
50 minus the shorts Shawnie borrowed (n) equal to 44

Factor the expression x2 − 5x − 24. A. (x − 4)(x + 6) B. (x − 3)(x + 8) C. (x + 3)(x − 8) D. (x + 4)(x − 6)
Answer:
C. (x + 3)(x − 8)
Step-by-step explanation:
We need two numbers that add to -5 and multiply to -24.
They are -8 and 3 since -8 + 3 = -5, and -8 * 3 = -24.
x^2 - 5x - 24 = (x - 8)(x + 3)

In 1994 the city of Anoka had a population of 18,000 people. Since then the population has grown by 5.2% each year. In 1994 the city of Minneapolis had a population of 390,000 and has been decreasing by 2.3% each year. How many more people will be living in Minneapolis compared to Anoka after 25 years?
Answer:
After 25 years, Minneapolis will have 154,062 more residents than Anoka.
Step-by-step explanation:
First, let's write a function for each case.
For Anoka, the initial population is 18,000. The population grows 5.2% or 0.052 each year. Thus:
[tex]A(x)=18000(1.052)^x[/tex], where x represents the amount of years after 1994.
Inversely, for Minneapolis, the population decreases by 2.3% or 0.023. Another way to write this is that it in changes by 1-0.023 or .977 or 97.7%. Thus:
[tex]M(x)=390000(0.977)^x[/tex].
To find how many more people are living in Minneapolis than Anoka after 25 years, simply plug 25 into the functions and then subtract.
In Anoka, after 25 years, there will be:
[tex]A(25)=18000(1.052)^{25}\approx 63924[/tex] residents.
In Minneapolis, after 25 years, there will be:
[tex]M(25)=390000(.977)^{25}\approx217986[/tex] residents.
217986-63924=154,062 residents.

is this right one more i think lol
Answer:
Yup P is the right one having 62.26%
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
We can set it up as
P = 33/53
Q = 20/48
R = 54/90
S = 44/83
This is because we are calculating the percent of yellow birds in the total amt. of birds in a specified park.
Now we calculate =>
P = 33/53 = around 0.62
Q = 20/48 = around 0.416
R = 54/90 = 0.6
S = 44/83 = around 0.53
We find that Park P has the greatest percentage and -->
Thus, Park P is our answer and yes, you are correct.
