The given equation is confusing since it written straight
without any symbols or parenthesis. I can write the equation in two forms:
(1 / 4) d + 7 --->
1
and
(1 / 4 d) + 7 --->
2
For equation 1, the variable d is first multiplied by 1 /
4 before adding up with the number 7. So in this case, the correct phrase would
be something like:
“The sum of one fourth a number and seven”
For equation 2, this is more complicated since the
variable is on the denominator side. The number 1 is divided by the product of
4 and variable d then summed up with the number 7. The correct phrase for this
one would be something like:
“The sum of the quotient of one over four times a number
and seven”
Select which equation is the correct one.
First find how much she makes per day for the 16 pages. Then divide it by the amount of hours she works to find her hourly average. So I guess you can use all these proportions.
Answer:
78°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relations between angles and sides of a right triangle. In particular, ...
Cos = Adjacent/Hypotenuse
cos(F) = FG/FE = 1.5/7.5 = 0.2
The inverse cosine function is used to find the angle:
∠F = arccos(0.2)
∠F ≈ 78°
Answer:
Necesitamos agregar 40 libras del café La Finca
Step-by-step explanation:
Sea x el número de libras de café de La Finca a mezclar.
Entonces, la cantidad total de libras que obtendremos en la mezcla será (x + 80) libras.
Ahora trabajemos con los precios; Tenemos x libras de La Finca a $ 5 por libra, con 80 libras de café a $ 2 por libra para dar una mezcla de (x + 80) a $ 3 Así, sumaremos el precio de La Finca más la otra variante para llegar al costo de la nueva mezcla.
Matemáticamente;
5 (x) + 2 (80) = 3 (x + 80)
5x + 160 = 3x + 240
5x -3x = 240-160
2x = 80
x = 80/2 x = 40
Answer:
Yes, the graph represents a proportional relationship. No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0).
