Answer:

Joseph tenía 240 soles

Step-by-step explanation:

Tenemos lo siguiente

Cantidad total = Cantidad gastada + Cantidad restante.

Sabemos que Cantidad gastada = 3/5 Cantidad restante y que Cantidad restante = Cantidad gastada + 60.

Sea x la cantidad gastada e y la cantidad restante. Tenemos las ecuaciones

x = \frac{3}{5}y, y = x+60

Reemplazando la segunda en la primera, tenemos que

x = \frac{3}{5}(x+60)= \frac{3}{5}x + 36 (aquí simplemente distribuímos la multiplicación.

Restando 3/5 x a ambos lados, tenemos que

x-\frac{3}{5}x = \frac{2}{5}x = 36

Multiplicando por 5 y dividiendo por dos ambos lados, tenemos que

x=\frac{5\cdot 36}{2} = 90

Es decir, Joseph gastó 90 soles. Entonces y = 90+60 = 150 soles.

Es decir, en total, Joseph tenía 150+90= 240 soles.

A professor has kept records on grades that students have earned in his class. If he wants to examine the percentage of students
AleksandrR [38]

Answer:

Pie chart

Step-by-step explanation:

Given that a  professor has kept records on grades that students have earned in his class

He wants to examine the percentage of students earning the grades A, B, C, D, and F during the most recent term,

We have to find which kind of plot could he make

Box plot gives comparison for interval of scores this is to some extent helpful to find out the percentage of students getting a range of scores

Timeplot is irrelevant here.  Dot plot will not be of much use.  

Histogram is to some extent useful as box plot

But the best one is pie chart giving easy visual comparison for various grades A, B,C,D,E and F

Find the area of the figure:  Select one: a. 59.5 yd^2 b. 81 yd^2 c. 58.5 yd^2 d. 55.3 yd^2
lions [1.4K]
Answer would be 58.5 yd^2 .

You should take the base of the triangle multiplied by the height.

Formula: 1/2×base×height

In this case, you know that base is 13yd and height is 9 yd.

So, apply the formula.

Area = 1/2(13yd)(9yd) = 58.5 yd^2

*Do not include the " invisible length as it is not part of the actual triangle.

*Do not include 32yd as it is a hypotenuse and not a base. Hypotenuse is a side that is opposite a right angle triangle.

Which number below best represents a depth of two meters below the ground?
Slav-nsk [51]

Answer:

-2

Step-by-step explanation:

We usually start measuring the height from the ground, so basically the positive direction is above the ground, for example  2 is the best number which represents 2m above the ground.

So the negative sign represents the depth below the ground.
