The local newspaper has letters to the editor from 50 people. If this number represents 4% of all of the newspaper's readers, how many readers does the newspaper have?
Answer:
[tex]1250[/tex]
Step-by-step explanation:
Let the number of people that are readers of the newspaper be [tex]x[/tex]
[tex]50[/tex] people represents [tex]4\%[/tex] of all the reader of the newspaper.
This means
[tex]\dfrac{4}{100}\times x=50[/tex]
[tex]\Rightarrow x=50\times\dfrac{100}{4}[/tex]
[tex]\Rightarrow x=1250[/tex]
So, the number of readers the newspaper has is [tex]1250[/tex].

The sum of two numbers is 85. The second number is 4 more than 2 times the first number. Let x represent the first number and let y represent the second number. What are the two numbers? Use the table to guess and check.
Step-by-step explanation:
x+y=85
y=4+2x
[tex]x = 85 - y \\ y = 4 + 2(85 - y) \\ y = 4 + 170 - 2y \\ 3y = 174 \\ y = 58 \\ x = 85 - y \\ x = 27[/tex]

What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is an expression as -
5 - 3(x + 1) = 2y - 3x + 2
The given expression is -
5 - 3(x + 1) = 2y - 3x + 2
5 - 3x - 3 = 2y - 3x + 2
2 - 3x = 2y - 3x + 2
2 - 3x + 3x - 2 = 2y
2y = 0
y = 0
y = 0x + 0
Therefore, we can write the given equation in the form of y = mx + b as -
y = 0x + 0.

20% of the girls in class have blonde hair. 16 girls do not have blonde hair. How many total students
A leopard is running with a velocity of 3 m/s. it then accelerates at 2 m/s² for 4 seconds.
use the formula:
v = u + at
to work out the final velocity of the leopard.
please can people reply and help me thank you
Using the formula:
v = u + at
Here s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.
In this case, u = 3m/s, a = 2m/s^2, t = 4s and we want to find final velocity, v, s, v = u + at
v = 3 + 2(4) = 11m/s
Hope this helps!
Does anyone know what the answer is
Thanks luvs xx

A plane’s average speed between Tucson and Phoenix is 600 km/hr. If the trip takes 0.75 hrs. How far does the plane fly?
Step-by-step explanation:
speed = Distance /Time
600 = Distance / 0.75
Distance = speed * Time
Distance = 600 * 0.75
Distance = 450 km

Use the spinner to find the theoretical probability of the event. Write your answer as a fraction or a percent rounded to the nearest tenth. Of red?
Complete question :
Picture relating to the question is attached below.
Answer:
1 / 3
Step-by-step explanation:
The Theoretical probability of an event is defined as :
P(event) = required outcome / Total possible outcomes
Based on the picture of the attached spinner below :
P(red) :
Required outcome = number of red partitions = 2
Total possible outcomes = total Number of partitions = 6
Hence,
P(Red) = 2 / 6 = 1/3

A certain radioactive substance decays from 100000 grams to 1000 grams in 34 days. What's it's half-life ?
Answer:
Half life of the radioactive element is 5 days.
Step-by-step explanation:
Formula to get the final amount after the radioactive decay in 't' days,
[tex]A_t=A_0e^{-\lambda t}[/tex]
Here [tex]A_0[/tex] = Initial amount
λ = Decay constant
t = duration of decay
[tex]A_t[/tex] = Final amount
[tex]1000=100000e^{-\lambda(34)}[/tex]
0.01 = [tex]e^{-34\lambda}[/tex]
ln(0.01) = [tex]\text{ln}(-e^{34\lambda}})[/tex]
-4.6052 = -34λ
λ = 0.13544
Since, λ = [tex]\frac{\text{ln}(2)}{t_{\frac{1}{2}}}[/tex]
[tex]t_{\frac{1}{2}}=\frac{\text{ln}2}{0.13544}[/tex]
= 5.11
≈ 5 days
Therefore, half life of the radioactive element is 5 days.

Ten baseballs and four ping-pong balls cost $46. One baseball costs one dollar more than two ping-pong balls. Find the cost of one baseball and the cost of one ping-pong ball.
Answer:
1 baseball cost $4
1 ping pong cost $1.5
Step-by-step explanation:
let the cost of baseball be b and the cost of ping pong be p
10 baseballs = 10b
4 ping pong = 4p
Adding both gives total $46
10b + 4p = 46 •••••••••(i)
baseball costs 1 dollar more than 2 ping pong
b = 2p + 1 •••••••(ii)
Substitute ii into i
10(2p + 1) + 4p = 46
20p + 10 + 4p = 46
24p = 46-10
24p = 36
p = 36/24
p = $1.5
b = 2p + 1
b = 2(1.5) + 1
b = 3 + 1 = $4
mortar is made by mixing water cement and sand in the following ratio 1 : 2 : 3 . how much of each component is needed to make 3kg of mortar
Answer:
To make 3 kg of water, we need
0.5 kg water
1 kg cement
1.5kg sand
Step-by-step explanation:
Here, we want to calculate the mass of each component needed to make 3 kg of mortar
We work with the ratio
Total ratio is:
1 + 2 + 3 = 6
water
1/6 * 3kg = 0.5 kg
cement
2/6 * 3 kg = 1 kg
sand
3/6 * 3 = 1.5 kg
