En total, Juan gastó $205.25. 1 kilo de queso cuesta $90. 1/2 kilo de jamón cuesta $60. Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129. Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas.
Dado que Juan compró 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6 y 4/8 de queso que cuesta $45, para determinar cuánto dinero gastó en total, cuánto cuesta un kilo de queso, cuánto cuesta medio kilo de jamón, cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón y, si Juan tiene $430, qué puede comprar sin que le sobre ni un peso, se deben realizar los siguientes cálculos:
Cuánto dinero gastó en total = valores x fracción comprada3 x 1/4 + 120 x 1 1/2 + 6 x 1/3 + 45 x 4/8 = X0.75 + 180 + 2 + 22.5 = X205.25 = XSi 4/8 de queso cuestan $45, y 4/8 es igual a 1/2, 1 kilo de queso cuesta $90 (45 x 2).Si 1 kilo de jamón cuestan $120, 1/2 kilo de jamón cuesta $60 (120 / 2).Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129 (3 + 6 + 120).Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas (120 x 3 + 45 + 3 x 5 + 6 + 6 x 0.666).Aprende más en https://brainly.com/question/15723794

Employees at a company are given £800 to spend on items for the office.
They decide to buy a coffee machine and as many bean bags as possible.
Bean bags cost £40 with an offer of "Buy at least 10 get 10% off the price."
The coffee machine costs £310.
How much will they have left over from the £800?
Answer:51273.816238
Step-by-step explanation:
Answer:
they have 490 to buy bean bags
If there is no discount, the amount they can buy is 490/40=12,25>10, so they will get a discount
call the bean bag is X we have: X*40*(100%-10%) ≤ 490
⇒X≤13,6
they can buy at most 13 bag and they will have left 490-40*13*90%=22

Line a and line c are perpendicular and m<26 = (5x+7). Find the value of x.
Answer in fraction form = 83/5
Answer in decimal form = 16.6
==================================================
Explanation:
All eight angles shown are 90 degrees since lines a and c are perpendicular to each other. Perpendicular lines form right angles.
Set 5x+7 equal to 90 and solve for x
5x+7 = 90
5x = 90-7
5x = 83
x = 83/5 is the fraction form of the answer
x = 16.6 is the decimal form of the answer
Answer:
83/5 = 16.6
Step-by-step explanation:
5x+7 = 90
5x = 90-7 subtract 7 from both sides.
5x = 83
x = 83/5 = 16.6

Two lighthouses are located 75 miles from one another on a north-south line. If a boat is spotted S 40o E from the northern lighthouse and N 21o E from the southern lighthouse, how much closer is the closest lighthouse to the boat than the lighthouse furthest away? The northern lighthouse is 51.3 miles closer than the southern lighthouse. The northern lighthouse is 24.4 miles closer than the southern lighthouse. The northern lighthouse is 79.9 miles closer than the southern lighthouse. The northern lighthouse is 17.0 miles closer than the southern lighthouse.
Answer:
The northern lighthouse is approximately [tex]24.4\; \rm mi[/tex] closer to the boat than the southern lighthouse.
Step-by-step explanation:
Refer to the diagram attached. Denote the northern lighthouse as [tex]\rm N[/tex], the southern lighthouse as [tex]\rm S[/tex], and the boat as [tex]\rm B[/tex]. These three points would form a triangle.
It is given that two of the angles of this triangle measure [tex]40^{\circ}[/tex] (northern lighthouse, [tex]\angle {\rm N}[/tex]) and [tex]21^{\circ}[/tex] (southern lighthouse [tex]\angle {\rm S}[/tex]), respectively. The three angles of any triangle add up to [tex]180^{\circ}[/tex]. Therefore, the third angle of this triangle would measure [tex]180^{\circ} - (40^{\circ} + 21^{\circ}) = 119^{\circ}[/tex] (boat [tex]\angle {\rm B}[/tex].)
It is also given that the length between the two lighthouses (length of [tex]\rm NS[/tex]) is [tex]75\; \rm mi[/tex].
By the law of sine, the length of a side in a given triangle would be proportional to the angle opposite to that side. For example, in the triangle in this question, [tex]\angle {\rm B}[/tex] is opposite to side [tex]\rm NS[/tex], whereas [tex]\angle {\rm S}[/tex] is opposite to side [tex]{\rm NB}[/tex]. Therefore:
[tex]\begin{aligned} \frac{\text{length of NS}}{\sin(\angle {\rm B})} = \frac{\text{length of NB}}{\sin(\angle {\rm S})} \end{aligned}[/tex].
Substitute in the known measurements:
[tex]\begin{aligned} \frac{75\; \rm mi}{\sin(119^{\circ})} = \frac{\text{length of NB}}{\sin(21^{\circ})} \end{aligned}[/tex].
Rearrange and solve for the length of [tex]\rm NB[/tex]:
[tex]\begin{aligned} & \text{length of NB} \\ =\; & (75\; \rm mi) \times \frac{\sin(21^{\circ})}{\sin(119^{\circ})} \\ \approx\; & 30.73\; \rm mi\end{aligned}[/tex].
(Round to at least one more decimal places than the values in the choices.)
Likewise, with [tex]\angle {\rm N}[/tex] is opposite to side [tex]{\rm SB}[/tex], the following would also hold:
[tex]\begin{aligned} \frac{\text{length of NS}}{\sin(\angle {\rm B})} = \frac{\text{length of SB}}{\sin(\angle {\rm N})} \end{aligned}[/tex].
[tex]\begin{aligned} \frac{75\; \rm mi}{\sin(119^{\circ})} = \frac{\text{length of SB}}{\sin(40^{\circ})} \end{aligned}[/tex].
[tex]\begin{aligned} & \text{length of SB} \\ =\; & (75\; \rm mi) \times \frac{\sin(40^{\circ})}{\sin(119^{\circ})} \\ \approx\; & 55.12\; \rm mi\end{aligned}[/tex].
In other words, the distance between the northern lighthouse and the boat is approximately [tex]30.73\; \rm mi[/tex], whereas the distance between the southern lighthouse and the boat is approximately [tex]55.12\; \rm mi[/tex]. Hence the conclusion.

I need these ASAP………..
Step-by-step explanation:
1) 3x - 4 = 86 + 24
→ 3x - 4 = 110
→ 3x = 110 + 4 = 114
→ x = 114/3 = 38
therefore, value of x is 38.
2) -10x = 30 + 90
→ -10x = 120
→ x = 120/10 = 12
→ x = 12
therefore, value of x is 12.
3) -8x + 23 + 51 = 130
→ -8x + 74 = 130
→ -8x = 130 - 74
→ -8x = 56
→ x = 56/8
→ x = 7
therefore, value of x is 7.
4) -9 + 2x = 59 + 90
→ -9 + 2x = 149
→ 2x = 149 + 9
→ 2x = 158
→ x = 158/2 = 79
→ x = 79
therefore, value of x is 79.

A rental car agency charges $220 per week plus $0.15 per mile to rent a car. How many miles can you travel in one week for $340?
The number of miles you can travel in one week for $340 is ?.
Answer:
800 miles
Step-by-step explanation:
You would make the equation .15x+ $200 and put that equal to 340 to get the equation:
.15x+$200=340
-$200 (subtract the like term first)
.15x=120
.15x over 120
Your answer comes out to be x=800.
