Answer:
Gabriela needs to sell 4 more cups of coffee to make a profit of $75.
She sells 90 cups and makes $0.80 profit on each cup. That equals $72 profit.
90 x $0.80= $72
She wants to make $75 profit.
$75 - $72 = $3 profit short for the day
$3/$0.80 = 3.75 cups of coffee short so to make her profit she must sell a total of 94 cups of coffee for the day or an additional 4 cups.

A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/25 for black, 1/5 for yellow,1/15 for blue, and 1/10 for white. What is the probability of pulling a black or yellow card, written as a reduced fraction?
Step-by-step explanation:
P(black or yellow) = P(black) + P(yellow) − P(black and yellow)
P(black or yellow) = 1/25 + 1/5 − 0
P(black or yellow) = 6/25
Why is (-5) to the 28th power positive but without parentheses it is negative?
Answer:= (10+5^2)*((5*-2)+9-3^3)/2
= (10+25)*((5*-2)+9-3^3)/2
= (35)*((5*-2)+9-3^3)/2
= 35*((5*-2)+9-3^3)/2
= 35*((-10)+9-3^3)/2
= 35*(-10+9-3^3)/2
= 35*(-10+9-27)/2
= 35*(-1-27)/2
= 35*(-28)/2
= 35*-28/2
= -980/2
= -490

Determine whether the geometric series 19.2 + 9.6 + 4.8 + ... converges or diverges, and identify the sum if it exists.
Answer: The infinite geometric series converges to 38.4
====================================================
Explanation:
Divide each term by its previous term
term2/term1 = 9.6/19.2 = 0.5
term3/term2 = 4.8/9.6 = 0.5
The common ratio is r = 0.5
Since -1 < r < 1 is true, this means the infinite geometric series converges.
It converges to...
S = a/(1-r)
S = 19.2/(1-0.5)
S = 38.4

Find the value of x in each case:
angle FEB = angle ABE ( Alternate Interior Angles )
angle FEB = 4x = angle ABE
Solution:x + 4x + 65° = 180° ( sum of the Angles On the same line is equal to 18° )
or, 5x = 180° - 65°
or, x = 115/5
or, x = 23
Answer:The value of x is 23°.
4x = 4(23) = 92°.
Una planta procesadora de alimentos desea producir 1000 litros de salsa de tomate con 30%de azúcar. Si tienen una salsa con 25% de azúcar y otra con 45%, ¿qué cantidad de cada clase de salsa deben emplear?
Answer: Tenemos que usar 750L de la salsa con 25% de azúcar, y 250% con la salsa de 45% de azúcar.
Step-by-step explanation:
Lo que tiene la planta es:
Una salsa con 25% de azúcar
Una salsa con 45% de azúcar.
Vamos a definir dos cantidades, A y B.
A es la cantidad de salsa con 25% de azúcar usada, y B es la cantidad de salsa con 45% de azúcar usada.
Como queremos producir 1000 litros de salsa, tenemos la ecuación:
A + B = 1000 L
Ahora, queremos que el producto final tenga 30% de azúcar.
El porcentaje de azúcar se define como:
(Cantidad de azúcar/Cantidad total de salsa)*100%.
Ahora, si la cantidad A tiene 25% de azúcar, entonces la cantidad total de azúcar es:
0.25*A
Y la cantidad B tiene 45% de azúcar, entonces acá la cantidad es:
0.45*B
Entonces cuando los mezclamos, la cantidad total de azúcar es:
(0.25*A + 0.45*B)
Y usando la formula de arriba, tenemos que:
100%*(0.25*A + 0.45*B)/(A + B) = 30%
Ahora divido ambos lados por 100%.
(0.25*A + 0.45*B)/(A + B) = 0.30
Entonces tenemos un sistema de dos ecuaciones:
A + B = 1000 L
(0.25*A + 0.45*B)/(A + B) = 0.30
El primer paso es aislar una de las variables en una de las ecuaciones, en este caso voy a aislar A en la primer ecuación:
A = 1000L - B
Ahora puedo reemplazar esto en la segunda ecuación:
(0.25(1000L - B) + 0.45*B)/(1000L - B + B) = 0.30
Y ahora lo resolvemos para B.
(250 L - 0.25*B + 0.45*B)/1000L = 0.30
250L + 0.20*B = 0.35*1000L = 300L
0.20*B = 300L - 250L = 50L
B = 50L/0.2 = 250L
Entonces:
A = 1000L - 250L = 750L.
Tenemos que usar 750L de la salsa con 25% de azúcar, y 250% con la salsa de 45% de azúcar.
Write an equation based on the word problem below and solve it. *
You have $150 in your savings
account. You earn money to
walk your neighbor's dog every
day after school. If it takes you
8 weeks to have $246 in your
account, how much money, m,
do you earn per week?
m = $13 per week
m = $12 per week
Om = $11 per week
O m = $10 per week
Answer:
m = $12 per week
Step-by-step explanation:
The equation would be 8m + $150 = $246. To find out how much money you earn a week, you need to solve for m.
First, subtract $150 from both sides of the equation. Doing so will leave you with an equation of 8m = $96.
Next, divide both sides by 8. This will leave you with m = $12, which is your final answer of how much money you earn a week.

Answer:f(g(0))= 1/5
g(f(0))= 7
Step-by-step explanation:
for f(g(0))=you solve for g(x) but you plug in 0 for x so g(0)= 8(0)+3
=3
so now you plug in the answer of the function of g(x) witch is 3 and plug it in as the x for F(x) so f(3)= 1/(3)+2
= 1/5
so f(g(0)) is equal to 1/5
Now for G(f(0)) you solve for f(x) by pluging 0 for x so F(0)= 1/(0)+2
=1/2
now you plug in 1/2 for the x of g(x) so g(1/2)= 8(1/2)+3
= 4+3
=7
so g(f(0)) is equal to 7
Hope this helps:)

Answer:
h = 435.779 m
Step-by-step explanation:
Step 1: Define variables
∅ = 5°
Hypotenuse (the road) = 5000 meters
We need to find height (or the vertical leg on the triangle) = h
Step 2: Use trig
sin∅ = opposite over hypotenuse
sin5° = h/5000
Step 3: Evaluate
5000sin5° = h
h = 435.779 m
Answer:
the increase of altitude is 435.8 m
Step-by-step explanation:
see attached
inclined road at 5°
after driving 5000 along the end road.
find:
increase of altitude (h)
let Ф = 5°
road = hypothenuse
using the formula Sin Ф = h ÷ hypothenuse
Sin(5) = h
5000
h = Sin (5) x 5000
h = 435.8 m
therefore,
the increase of altitude is 435.8 m
If a2 = 5 and a8 = 35, what is the value of a30?
Answer:
a(30) = 145
Step-by-step explanation:
a(n) = a(1) + (n-1)d
d = 5
a(30) = 0 + (30-1)5
a(30) = 0 + (29)5
a(30) = 0 + 145
a(30) = 145
Using the concept of arithmetic sequence, the value of a30, which is the 30th term of the sequence is 145
The common difference, d = 35 / 7 = 5
The nth term of an arithmetic sequence is obtained using the relation :
A(n) = a1 + (n - 1)da1 = first terma1 = a2 - d = 5 - 5 = 0
Hence,
A(30) = 0 + (30 - 1)5
A(30) = 0 + 29(5)
A(30) = 145
Therefore, the value of the 30th term of the sequence is 145.
