1. The cards bearing letters of word “MATHEMATICS” are placed in a bag. Find the probability of getting: (a) any vowel. (b) any consonant. (c) the letter ‘m’. 2. 8 added to twice a number gives 40. Find the number
Answer:
1) 30%, 50%, 10%
2) x = 24
Step-by-step explanation:
Hey there!
1) "MATHMATICS"
a) Vowels - a, e, i, o, u
This is 3/10 of the letters meaning pulling a vowel is 30%.
b) Constants - B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, X, Z
Well there are 5 constants in mathematics so the percent is 50%.
c) Letter "m"
The letter m is 1/10 meaning pulling the letter m is a 10%.
2) 8 added to twice a number gives 40. Find the number
Well lets set u an equation,
8 + x + 8 = 40
16 + x = 40
-16
x = 24
Hope this helps :)
Answer:
In bold.
Step-by-step explanation:
1.
There are a total of 11 letters in the bag including 4 vowels, 7 consonants.
The letter m appears twice in mathematics.
(a) Probability(getting a vowel) = 4/11.
(b) Probability(getting a consonant) = 7/11.
(c) Probability(getting a letter m) = 2/11.
2.
Let the number be n, then:
8 + 2n = 40
2n = 32
n = 16.
Find the number by which 4732 should be divided to get perfect square.
Answer:
7
Step-by-step explanation:
Prime factors of 4732:
4732 = 2² × 7 × 13²As we see if we remove 7 from the factors list, we get the perfect square of 2²×13²= 26²
So the number by which 4732 should be divided is 7
4732/7 = 676 = 26²What is the solution set of the following equation? 4\5^2= 2x- 4\5

for each diagram, determine whether angles 1 & 2 form a linear pair, heeelp please :(
Answer:
only (12) has a linear pair
Step-by-step explanation:
Recall that for two angles to be called a "Linear Pair", they need to satisfy several conditions:
1) The two lines must intersect at a shared point (i.e common vertex)
2) The two angles must be adjacent (i.e immediately next to one another)
3) The two angles must add up to 180 degrees.
In our case,
in (9), the angles are not adjacent and they do not add up to 180 deg, so this is NOT a linear pair
in (10), the angles are not adjacent and they do not add up to 180 deg, so this is NOT a linear pair
in (11), the lines do not intersect at a shared point(they do not have a common vertex). Plus we cannot be 100% sure that they add up to 180 deg. Hence this is not a linear pari
in (12), we can see that the angles satisfy all 3 conditions above. This is a linear pair.
hydrogen and oxygen come pouring out it drips and it dribbles and it comes from a spout
Answer:
[tex]\Large \boxed{\mathrm{Water}}[/tex]
Step-by-step explanation:
Hydrogen and oxygen are elements that form the compound known as water.
Water comes pouring out, it drips, it dribbles, and it comes from a spout.
Answer:
Water
Step-by-step explanation:
Most of the water in our world is a combination of "ordinary" hydrogen atoms with "ordinary" oxygen atoms, but there are actually three different istopes (atomic varieties) of hydrogen and each of those can combine with oxygen to give a different kind of water.
If deuterium (hydrogen whose atoms contain one neutron and one proton instead of just one proton by itself) combines with oxygen, we get something called heavy water, which is about 10% heavier than normal water.
Similarly, tritium (hydrogen with two neutrons and one proton) can combine with oxygen to make something called super heavy water.
Water comes pouring out it drips and it dribbles and it comes from a spout.
Make M the subject of the expression T = WP [ M² - ( M-S)² ]
Answer:
see below (I hope this helps!)
Step-by-step explanation:
T = WP [ M² - (M - S)² ]
T = WP [ M² - (M² - 2MS + S²) ]
T = WP (2MS - S²)
T = 2WPMS - WPS²
T + WPS² = 2WPMS

Sales Rise from 2000 per week to 2500 per week, calculate the percentage change..
Answer:
[tex]\huge\boxed{25\%}[/tex]
Step-by-step explanation:
Previous Price = 2000
Current = 2500
Increase:
=> 2500 - 2000
=> 500
%age change:
=> [tex]\frac{500}{2000} * 100 \%[/tex]
=> ( 5 * 5 ) %
=> 25%
Answer:
Percentage change = 25%Step-by-step explanation:
To find the percentage change we use the formula
[tex]Percentage \: \: change \: \: = \frac{change}{original \: \: quantity} \times 100[/tex]To find the change subtract the lesser one from the larger one
Original price = 2000
Final price = 2500
Change = 2500 - 2000 = 500
So the percentage change is
[tex] \frac{500}{2000} \times 100[/tex][tex] = \frac{1}{4} \times 100[/tex]We have the final answer
Percentage change = 25%Hope this helps you

The length of a rectangle is 6 meters less than twice its width. If the area of the rectangle is 308 m2, what are its dimensions?
Answer:
length = 22cmwidth = 14cmStep-by-step explanation:
Area of a rectangle = l × w
where
l is the length
w is the width
From the question
Area = 308 m²
The length of a rectangle is 6 meters less than twice its width is written as
l = 2w - 6
Substitute this into the above formula and solve for the width
We have
308 = (2w - 6)w
2w² - 6w = 308
2w² - 6w - 308 = 0
Divide both sides by 2
We have
w² - 3w - 154 = 0
( w + 11)( w - 14) = 0
w + 11 = 0 w - 14 = 0
w = - 11 w = 14
Since the width cannot be negative
w = 14
Substitute w = 14 into l = 2w - 6
That's
l = 14(2) - 6
l = 28 - 6
l = 22
Therefore
length = 22cm
width = 14cm
Hope this helps you

How many metal doorstops 15 cm by 10 cm by 5 cm can be cast from a spherical ball of metal of diameter 400 mm?
Answer:
[tex]\approx \bold{44\ or\ 45}[/tex]
Step-by-step explanation:
Given
Diameter of spherical metal ball = 400 mm = 40 cm
Radius of spherical metal ball = 20 cm
Volume of a sphere is given as:
[tex]V_{Sphere} = \dfrac{4}{3}\pi r^3[/tex]
[tex]\Rightarrow \dfrac{4}3 \times 3.14 \times 20 ^3 = 33493.33 \ cm^3[/tex]
Dimensions of metal doorstops = 15 cm by 10 cm by 5 cm
It is of cuboid shape.
Volume of a cuboid is given as:
[tex]V_{Cuboid} = l \times b\times h = 15 \times 10 \times 5 = 750\ cm^3[/tex]
Number of such doorsteps that can be made from the metal ball is equal to Volume of metal ball divided by volume of metal doorstep.
[tex]\dfrac{33493.33}{750} \approx \bold{44\ or\ 45}[/tex]

Mrs. Grundy has two children. Given that Mrs. Grundy has at least one child born on a Monday, what is the probability that both her children were born on Mondays? Assume that each child was equally likely to be born on any day of the week, and that the two birthdays are independent (Mrs. Grundy doesn't have twins!).
Answer:
1/7
Step-by-step explanation:
If one child was born on a Monday, then we don't have to consider that when solving the question, as it asks if both children were born on a Monday.
Thus, we only need to find the probability that the second child is born on a Monday. Since there are 7 days in a week and equally likely that the child is born on any day, then the probability of the child being born on a Monday would be 1/7.

Please help me with question
Answer:
4 hours 7 minutes
Step-by-step explanation:
Since Trevon takes 10 hours to clean the attic, he cleans 1/10, 10% or .1 of the attic per hour. Since Cody takes 7 hours to clean the attic, he cleans 1/7, 14.3% or .143 of the attic per hour.
Together, that means they clean .1 + .143 of the attic per hour. That's an hourly rate of:
.1 + .143 = .243
The portion of the attic they clean in x hours is .243x. We'd like to know how long it will take them to clean 100% or 1 of the attic. So:
.243x = 1 Divide each side by .243
x = 1/.243
x ≈ 4.115
Let's convert .115 to minutes by multiplying by 60
.115 * 60 = 6.9 round to 7 for 7 minutes
It will take them around 4 hours 7 minutes to clean the attic.

HELP PLEASE The value of a stock can be modeled by this equation. V = 23n + 42; where V is the value, in dollars, and n represents the number of months since purchase. Which statements correctly interpret the slope of the line? A. The slope of the line is 42. This means that the value of the stock increases $42 for each additional month since purchase. B. The slope of the line is 42. This means that the initial value of the stock was $42. C. The slope of the line is 23. This means that the initial value of the stock was $23. D. The slope of the line is 23. This means that the value of the stock increases $23 for each additional month since purchase.
Answer:
D. The slope of the line is 23. This means that the value of the stock increases $23 for each additional month since purchase.
Step-by-step explanation:
In the basic equation y = mx + b, m is the slope. In this situation, 23 is the slope because it is the coefficient.
42 is not the slope because it is the y-intercept.
D is the correct answer because the slope is 23, which means in this situation that the stock's value increases by $23 for each additional month after the purchase.
Answer:
D.
Step-by-step explanation:
The slope is the coefficient of n ( the month) which is 23.
This means the stock increases each month by a factor of 23.
