w is directly proportional to y
w is inversely proportional to x?
(a) When y = 4, w = 14
Work out the value of w when y = 9
Answer:
w=31.5
Step-by-step explanation:
w proportional to y
w=ky
k is a constant
k=w/y
w1/y1=w2/y2
w1=14,w2=?,y1=4,y2=9
14/4=w/9
cross multiply and divide by 4
w=14×9/4
w=31.5
Find the period of an electromagnetic wave of wavelength 2.20 × 10–2 m. A. 1.36 × 1010 s c. 7.33 × 10–11 s b. 4.54 × 101 s d. 6.60 × 106 s
Answer:
7.33 * 10^-11 s
Step-by-step explanation:
Period, T = 1 / f
c = fλ
λ = 2.20 × 10^–2 m
c = speed of light = 3 * 10^8 m
f = c / λ
f = 3 * 10^8 ÷ 2.20 × 10^–2 m
f = (3/2.2) * 10^(8-(-2))
f = 1.364 * 10^10
T = 1/f
T = 1 / 1.364 * 10^10
T = 7.33 * 10^-11 s
The five-number summary for a data set is given by min = 5, Q1 = 18, median = 20, Q3 = 40, max = 75. If you wanted to construct a boxplot for the data set (that is, one that would show outliers, if any existed), what would be the maximum possible length of the right-side "whisker"? * 2 points 53 35 55 33 45
Answer:
33
Step-by-step explanation:
Values beyond the whiskers of the boxplot are called the outliers :
For a right side Outlier :
Values > Q3 ± 1.5(IQR) ;
IQR = Q3 - Q1)
From the data given:
IQR = (40 - 18) = 22
Hence ; the maximum value of right side whisker will be :
1.5(22) = 33
The maximum possible length of the right-side "whisker" is 33
The given parameters are:
Min = 15Q1 = 18Median = 20Q3 = 40Max = 75Start by calculating the interquartile range (IQR) using:
[tex]IQR = Q3 -Q1[/tex]
So, we have
[tex]IQR = 40 - 18[/tex]
[tex]IQR = 22[/tex]
The maximum possible length of the right side whisker is then calculated as:
[tex]L = 1.5 \times IQR[/tex]
This gives
[tex]L = 1.5 \times 22[/tex]
Multiply 1.5 by 22
[tex]L = 33[/tex]
Hence, the maximum possible length of the right-side "whisker" is 33

There are 150 students at the zoo. 90 of the students visited the gorilla
exhibit. What percent of the students visited the gorilla exhibit? *
Divide the number that visited the gorilla by the total students at the zoo then multiply by 100
90/150 = 0.6
0.6 x 109 = 60%
The answer is 60%
[tex] \frac{is}{of} = \frac{x}{100} [/tex]
[tex] \frac{150}{90} = \frac{x}{100} [/tex]
150 × 100 = 15,000
90x = 15,000
90 ÷ 90 = 1
15,000 ÷ 90 = 166.6%
I don’t know of the problem wants you to round but the percent would be either 166.6% or 167% (if rounded).

Answer:
189 yd²
Step-by-step explanation:
so in a prism, there are total 5 surfaces;
3 rectangular(all of same size)
2 triangular (of same sizes too)
so the area of trangle = 1/2× base × height = 1/2 × 6× 4 = 12yd²
for two triangles, Area= 24 yd²
area of a rectangle= length× breadth = 11× 5 = 55yd²
for three rectangles, area= 165yd²
now you add them
total surface area = 24+ 165= 189yd²

P = 2(l+w) for a rectangle
Substitute in the length and the width
P = 2( 21+11)
P = 2( 32)
P = 64 meters
Answer:
P = 2(l+w)
= 2 ( 21+11)

ANSWER CHOICES
oA. 96m^3
oB. 384 pi m^3
oC. 96 pi m^3
oD. 288 pi m^3
Answer:
V = 96 pi m^3
Step-by-step explanation:
V = (1/3) pi(r^2)h
Radius = 1/2(Diameter)
R = 1/2(12)
R = 6
Input.
V = (1/3) pi(6^2)8
Solve.
V = (1/3) pi(36)8
V = (1/3) 904.32
V = 301.44
V = 301.44/pi
V = 96 pi m^3
Answer:
The correct answer is option (C) 96π m³.
Step-by-step explanation:
As per given question we have provided that :
⟶ Diameter = 12 m⟶ Radius = 12/2 = 6 m⟶ Height = 8 mHere's the required formula to find the volume of cone :
[tex]{\longrightarrow{\pmb{\sf{V_{(Cone)} = \dfrac{1}{3}\pi{r}^{2}h}}}}[/tex]
➝ V = Volume➝ π = 22/7➝ r = radius➝ h = heightSubstituting all the given values in the formula to find the volume of cone :
[tex]{\implies{\sf{V_{(Cone)} = \dfrac{1}{3}\pi{r}^{2}h}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} = \dfrac{1}{3}\pi{(6)}^{2}8}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} = \dfrac{1}{3}\pi{(6 \times 6)}8}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} = \dfrac{1}{3}\pi \times {(36)} \times 8}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} = \dfrac{1}{3} \times \pi \times 36 \times 8}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} = \dfrac{1}{\cancel{3}} \times \pi \times \cancel{36} \times 8}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} = \pi \times 12 \times 8}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} = \pi \times 96}}}[/tex]
[tex]{\implies{\sf{V_{(Cone)} =96\pi}}}[/tex]
[tex]\star{\underline{\boxed{\sf{\red{V_{(Cone)} =96\pi \: {m}^{3}}}}}}[/tex]
Hence, the volume of cone is 96π m³.

2. Radius: ??
3. Diameter: ??
Answer:
See below
Step-by-step explanation:
Center: (-3, 4)
radius = r = [tex]\sqrt{25}[/tex] = 5
diameter = 2r = 10
Answer:
Center= (3,-4) Radius=5 Diameter=10
Step-by-step explanation:
The numbers (3,-4) are the coordinates in the center of a circle. The radius is squared to get the end number so to get the radius, you have to find its square root- [tex]\sqrt{25[/tex] =5. The diameter is 2 times bigger than the radius so 5 times 2= 10.
