-26.4 % -35.8?
Please help
Answer:
-36.064 (?)
Step-by-step explanation:
-26.4% -35.8
= -33/125 -35.8
-33/125 = 0.264, = -0.264-35.8
Subtract the numbers: -0.264-35.8=-36.064

El Papa de blanca destino la tercera parte de su salario quincenal para comprar alimentos y la mitad para pagos diversos si le sobran 500 ¿que cantidad de su sueldo gasta en alimentos?
Answer:
El papá de Blanca gasta $1,000 de su sueldo en alimentos.
Step-by-step explanation:
En primer lugar, se designa a la letra S como la cantidad total del salario de la persona.
Sabiendo que el papá de Blanca destina la tercera parte de su salario para comprar alimentos, y que la tercera parte de un número es la división de ese número entre tres, entonces se tiene la expresión:
Alimentos: [tex]A=\frac{S}{3} =\frac{1}{3} *S[/tex]
Ahora sabes que el papá de Blanca destina la mitad de su salario en diversos gastos, y siendo la mitad de un número es la división de ese número entre dos, se obtiene la expresión:
Gastos: [tex]G=\frac{S}{2} =\frac{1}{2} S[/tex]
El papá de Blanca gasta su salario en alimentos y en otros gastos y le sobran $ 500. Esto es expresado mediante:
Alimentos + Gastos + 500 = Salario
Entonces:
A + G + 500 = S
Sustituyendo A y G:
[tex]\frac{1}{3} S+\frac{1}{2} S+500=S[/tex]
Resolviendo:
[tex]\frac{5}{6} S+500=S[/tex]
[tex]500=S- \frac{5}{6} S[/tex]
[tex]500= \frac{1}{6} S[/tex]
[tex]\frac{500}{\frac{1}{6} } =S[/tex]
3,000= S
Entonces el salario del papá de Blanca es de $ 3,000
Reemplazando este valor para el cálculo de su gasto en alimentos es:
[tex]A=\frac{1}{3} *S= \frac{1}{3}* 3,000[/tex]
A= 1,000
El papá de Blanca gasta $1,000 de su sueldo en alimentos.

Step-by-step explanation:
A well-detailed version of the question has been uploaded in form of an image for easier understand.
Looking at the question, it was said that she received her store order on 12/3/2016 at 4am, this implies that the prep date and time are 12/3/2016 and 4am respectively. Also, it was said that the expiration date was printed on the product and it is 1/17/2017. Obviously, the expiration time would also be 4am because it was prepared at 4am and if we calculate in. 24hours we would get 4am at the expiration date as well. Lastly, we were told she opened the product she received on 12/7/2016 which is the initial date the product was used. From all these we can deduce the following:
Exp Date: 1/17/2017
Exp Time: 4:00am

An NFL team kicker misses 2 out of every 11 field goals. If he missed 8 field goals throughout the season, how many did he attempt?
Answer:
44
Step-by-step explanation:
8/2=4
4x11=44
He attempted 44 field goals throughout the season. :)
Hope this helps and I'd appreciate a brainliest.
Answer: The kicker must have attempted 44 field goals.
Step-by-step explanation:
If the kicker missed 2 out of every eleven field goals, then this is a division and multiplication problem.
8 ÷ 2 lets us know what number to multiply 11 by, which in this case, is 4.
4 x 11 = 44, and in the context of the question, this would mean that the kicker attempted 44 total field goals.

Write the equation of a line that passes through the points in the table.
x (-1, -4, -7)
y (5, 11, 17
Answer:
y = -2x + 3
Step-by-step explanation:
Lets just put the three points together.
(-1, 5) (-4, 11) (-7, 17)
First let's find the slope with y2 - y1/x2 - x1
Plug in using (-1, 5) and (-4, 11)
11 - 5/-4 + 1 = 6/-3 (simplify)
-2 is the slope
Now plug in (-7, 17) in the equation to get b or the y-intercept)
y = mx + b
17 = -2(-7) + b
17 = 14 + b (subtract 14 on both sides)
3 = b
y = -2x + 3
The equation of the line that passes through the points in the table is:[tex]y = -2x +3[/tex]
The line passes through the following points
x (-1, -4, -7)
y (5, 11, 17)
Start by calculating the slope (m) of the line
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{17 - 11}{-4+1}[/tex]
Evaluate the differences
[tex]m = \frac{6}{-3}[/tex]
Evaluate the quotient
[tex]m = -2[/tex]
The equation is then calculated as:
[tex]y = m(x -x_1) +y_1[/tex]
This gives
[tex]y = -2(x+1) +5[/tex]
Open the brackets
[tex]y = -2x-2 +5[/tex]
Evaluate the like terms
[tex]y = -2x +3[/tex]
Hence, the equation of the line is:[tex]y = -2x +3[/tex]

Which expression is equivalent to 10 - 6(5 - 2y)?
Answer:4(-5+3y) or -20+12y

Order of operations states you have to distribute -6 to (5-2y) before you subtract anything from 10.
-6(5-2y) = -30 + 12y
10 - 30 + 12y = -20 + 12y

The function LaTeX: f\left(x\right)=-x^2+4f ( x ) = − x 2 + 4 defined on the interval LaTeX: -8\le x\le8− 8 ≤ x ≤ 8 is increasing on the interval LaTeX: \left[A,B\right][ A , B ] and decreasing on the interval LaTeX: \left[C,D\right][ C , D ]. Fill in the blanks below.
Given:
The function is
[tex]f(x)=-x^2+4[/tex]
It defined on the interval -8 ≤ x ≤ 8.
To find:
The intervals on which the function is increasing and the interval on which decreasing.
Step-by-step explanation:
We have,
[tex]f(x)=-x^2+4[/tex]
Differentiate with respect to x.
[tex]f'(x)=-(2x)+(0)[/tex]
[tex]f'(x)=-2x[/tex]
For turning point f'(x)=0.
[tex]-2x=0[/tex]
[tex]x=0[/tex]
Now, 0 divides the interval -8 ≤ x ≤ 8 in two parts [-8,0] and [0,8]
For interval [-8,0], f'(x)>0, it means increasing.
For interval [0,8], f'(x)<0, it means decreasing.
Therefore, the function is increasing on the interval [-8,0] and decreasing on the interval [0,8].

9.) A new basketball is $10.95 and is 20% off. The sales tax is 7%.
If you are trying to find the cost of the basket ball, it is $8.15.
Step 1: Find 20% of 10.95- which is 2.19- and subtract 2.19 from 10.95-which is 8.76.
Step 2: Find 7% of 8.76-which is 0.6132- and subtract 0.6132 from 8.76-which is 8.1468
Step 3: Round to the nearest hundredth, which gives you 8.15.
Thus, $8.15 is your answer.
Luke receives an electric bill of \$84.21$84.21dollar sign, 84, point, 21 for the month of April. The electric company charges \$0.14$0.14dollar sign, 0, point, 14 per kilowatt-hour (\text{kWh})(kWh)left parenthesis, start text, k, W, h, end text, right parenthesis of electricity. Given that April has 303030 days, about how many kilowatt-hours did Luke use per day during the month of April?
Answer:
20.05 kilowatt-hour
Step-by-step explanation:
Total electric bill = $84.21
Charges per kilowatt-hour = $0.14
Days in April = 30 days
Number of hours = x
Total electric bill = Charges per kilowatt-hour × Days in April × Number of hours
84.21 = 0.14 * 30 * x
84.21 = 4.2 * x
84.21 = 4.2x
Divide both sides by 4.2
x = 84.21 / 4.2
= 20.05
x = 20.05 kilowatt-hour
Therefore, Luke use 20.05 kilowatt-hour per day during the month of April

and add your steps to solve
Answer:
x = 4
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 4 from both sides of the equation:
-6x + 4 (-4) = -20 (-4)
-6x = -20 - 4
-6x = -24
Next, divide -6 from both sides of the equation:
(-6x)/-6 = (-24)/-6
x = (-24)/(-6)
x = 4
x = 4 is your answer.
