Answer:
14%
Step-by-step explanation:
42 ÷ 300 = 0.14 = 14%
or
subtract 42 from 300 which gives you 258
258 is 86% of 300
86-100 is 14 so 14%
solve the linear equation 1/5(10x-20)=x-3
Answer:
x=1
Step-by-step explanation:
1/5(10x-20)=x-3
2x-4=x-3
2x-x=4-3
x=1
Answer:
The value of x is 1 after solving the linear equation.
Step-by-step explanation:
Given equation is:
[tex]\frac{1}{5}(10x-20)=x-3[/tex]
We will solve the equation by simplifying first.
[tex]\frac{1}{5}*10x-\frac{1}{5}*{20}=x-3\\2x-4=x-3[/tex]
Now, we will subtract x from both sides of the equation,
2x-x-4 = x-x-3
x-4 = -3
Next, we will add 4 on the both sides of the equation,
x-4+4 = -3+4
x = 1
Hence,
The value of x is 1 after solving the linear equation.

Answer:
x < - 7
Step-by-step explanation:
Given
- 3x + 4 > 25 ( subtract 4 from both sides )
- 3x > 21
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.

Lara makes birdseed by mixing peanuts and sunflower seeds in a 2:3 ratio. The peanuts costs 3p per 10g and the sunflower seeds cost 9p per 10g. Lara sells the birdseed £1 per 100g portion.
How much profit does Lara make on each portion? Give your answer in pence.
Step by step explanation plssss tqsm.
Answer:
Lara will do a profit of 34 pence by 100 grams of birdseed.
Step-by-step explanation:
The given ratio means that there are 2 grams of peanuts and 3 grams of sunflower per each 5 grams of birdseed. Now, we obtain the amount required of peanuts and sunflower for 100 grams of birdseed by simple rule of three:
Peanuts
[tex]x = \frac{100\,g}{5\,g}\times 2\,g[/tex]
[tex]x = 40\,g[/tex]
Sunflower
[tex]y = \frac{100\,g}{5\,g}\times 3\,g[/tex]
[tex]y = 60\,g[/tex]
If we know that 10 grams of sunflower cost 9 pence and 10 grams of sunflower cost 3 pence, then the total cost of production of 100 grams portion:
[tex]C = \left(\frac{0.03\,GBP}{10\,g} \right)\cdot (40\,g)+\left(\frac{0.09\,GBP}{10\,g} \right)\cdot (60\,g)[/tex]
[tex]C = 0.66\,GBP[/tex]
And the profit done by Lara is:
[tex]\Delta C = 1\,GBP - 0.66\,GBP[/tex]
[tex]\Delta C = 0.34\,GBP[/tex]
Lara will do a profit of 34 pence by 100 grams of birdseed.

Answer:
A. 3.7, because |3.7| = 3.7
Step-by-step explanation:
What the question is referring her by magnitude is units away from 0. 3.7 is 3.7 units away from 0, which is the same thing as the absolute value of 3.7. And since absolute value is always positive, C is already out. D is also out as the value doesn't change. B's reason contradicts the answer, so it is also wrong. This leaves A (3.7, because |3.7| = 3.7) as our answer.

3. Problema 2: Suponga que un fabricante de radios tiene la función de costo total C (x) = 43x + 1850 dólares y la función de ingreso R (x) = 80x dólares. Donde "x" es el número de radios fabricados y vendidos. Halle:
Responder:
$ 11,137
Explicación paso a paso:
Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.
Dado
Función de costo C (x) = 43x + 1850
Función de ingresos R (x) = 80x
Obtener la función de ganancias
P (x) = R (x) - C (x)
P (x) = 80x - (43x + 1850)
P (x) = 80x - 43x - 1850
P (x) = 37x - 1850
Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:
P (351) = 37 (351) - 1850
P (351) = 12,987-1850
P (351) = 11,137
Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137
Hunter invested $750 in an account paying an interest rate of 6\tfrac{5}{8}6 8 5 % compounded continuously. London invested $750 in an account paying an interest rate of 6\tfrac{1}{2}6 2 1 % compounded daily. After 18 years, how much more money would Hunter have in his account than London, to the nearest dollar?
Answer: $ 55
Step-by-step explanation:
When interest is compounded continuously, the final amount will be
[tex]A=Pe^{rt}[/tex]
When interest is compounded daily, the final amount will be
[tex]A=P(1+\dfrac{r}{365})^{365t}[/tex]
, where P= Principal , r = rate of interest , t = time
For Hunter , P= $750, r = [tex]6\dfrac{5}{8}\%=\dfrac{53}{8}\%=\dfrac{53}{800}=0.06625[/tex]
t = 18 years
[tex]A=750e^{0.06625(18)}=\$2471.48[/tex]
For London , P= $750, r = [tex]6\dfrac{1}{2}\%=\dfrac{13}{2}\%=\neq \dfrac{13}{200}=0.065[/tex]
t = 18 years
[tex]A=750(1+\dfrac{0.065}{365})^{18(365)}=\$2416.24[/tex]
Difference = $ 2471.48 - $ 2416.24 =$ 55.24≈$ 55
Hence, Hunter would have $ 55 more than London in his account .

Simplify an expression for the perimater of the equilateral triangle shown blown
Answer:
5.25x-6
Step-by-step explanation:
Hosea borrowed $20,000 to buy a new speed boat. The interest rate on his loan is 5%. If he plans to pay the loan back in three years, how much interest will he pay? What will be the total cost that he will owe including interest?
Answer:
a. Interest amount is $3,000.
b. Total cost is $23,000.
Step-by-step explanation:
a. How much interest will he pay
This can be calculated as follows:
Interest amount = Principal loan Amount * Interest rate * Number of years ........ (1)
Where;
Principal loan Amount = $20,000
Interest rate = 5%
Number of years = 3
Substituting the values into equation (1), we have:
Interest amount = $20,000 * 5% * 3 = $3,000
b. What will be the total cost that he will owe including interest?
Total cost = Principal loan Amount + Interest amount = $20,000 + $3,000 = $23,000

Answer:
I would say A because 6:3 can only equal 1/3.
Step-by-step explanation:
It would help if you formatted a bit better though. As the choices are not clear. ^^
The probability of getting numbers whose sum is a multiple of three is,
⇒ 1 / 3
Since, The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Here, We have;
There are 48 possible outcomes in this situation, and of those outcomes, the ones whose sums are a multiple of three are;
12, 21, 15, 51, 24, 42, 33, 18, 27, 36, 63, 45, 54, 48, 57, and 66.
So, that is 16 out of 48 possibilities,
⇒ 16/48,
⇒ 1/3.
Thus, The probability of getting numbers whose sum is a multiple of three is,
⇒ 1 / 3
