You spend 2/5 of your money on lunch. Your friend then pays you back a loan of $5.50. Later that day you spend $9.75 on a movie ticket and $4.50 on a snack. You have $12.65 left. How much money did you have before lunch?

Answer:

60 kilograms of the 30% solution

140 kilograms of the 40% solution

Step-by-step explanation:

Let x = the no. of kilos containing 30% salt (solution 1)

and 200 - x = the no. of kilos containging 40% salt solution 2)

.30x = amount of salt in solution 1

.40(200 - x) = amount of salt in solution 2

.37(200) = amount of salt in the final mixture

salt in solution 1 + salt in solution 2 = salt in final mix.

.30x + .40(200 - x) = .37(200)  

Let's multiply thru the equation by 100 to remove the decimal fractions

30x + 40(200 - x) = 37(200)

30x + 8000 - 40x = 7400

-10x = -600

x = 60 kilograms of the 30% solution

200 - 60 = 140 kilograms of the 40% solution

Answer B

Answer:

( 5/2,5/2)

Step-by-step explanation:

Answer:

x = 0

Step-by-step explanation:

its quite simple because 10 raised to the power '0' is 1, so 41,630 ×1 is the same.

don't know about the second figure but the comma doesn't change it..

i hope this help

sorry of it's wrong ☺️

Okay, so not sure what your question is, but this should help

X = 2

Y = 3

X = 8

Y=12

X = 8+2 = 10

Y = 12+3 = 15

15/10= 1.5

X = 1

Y = 1.5

Answer:x

y = [tex]\frac{x}{2}[/tex]+x

y=[tex]\frac{3}{2} x[/tex]

Answer:

9:15 or 3:5

Step-by-step explanation:

A ratio can compare a part of a whole to a whole.

In this case, our whole is the total number of shots attempted: 15.

The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.

Put these values in a ration.

part:whole

9:15

Notice that 9 and 15 can be simplified by dividing both numbers by 3.

3:5

This is your simplified ratio.

Hope this helps!

121 000

Explicación paso a paso:

Dado que :

Monto del crédito = 110.000; este es el monto principal, P del préstamo

Tasa de interés = 10% = 10/100 = 0.1

Usando la relación para determinar el monto a pagar al final del año:

A = P (1 + rt)

A = monto final

A = 110 000 (1 + 0,1 * 1)

A = 11 000 (1 + 0,1)

A = 110 000 (1,1)

A = 121 000

La cantidad a pagar al final del año = 121.000

Answer:

4 mph

Step-by-step explanation:

2/3 mile in 1/6 hour

x 6 to make it 1 hour

(6/1)(2/3) = 4

(6/1)(1/6) = 1

4 mph

Answer:

1)4.59 *10^7

2)2.56 *10 ^13

3)3.892 *10 ^10

4)5.03 *10 ^11

Answer:

Part A is not a rt triangle

Part B is not a rt triangle

Part C is a rt triangle

Step-by-step explanation:

Part A:

290^2 + 696^2 = 750^2

84,100 + 484,416 = 562,500

Add the numbers on the left to see if the 2 sides are equal.

568,516 ≠ 562,500

Part B:

514^2 + 684^2 = 855^2

264,196 + 467,856 = 731,025

Add the numbers on the left to see if the 2 sides are equal.

732,052 ≠ 731,025

Part C:

450^2 + 1080^2 = 1170^2

202,500 + 1,166,400 = 1,368,900

1,368,900 = 1,368,900

Answer:

Function 2

Step-by-step explanation:

✔️Slope of function 1:

Slope (m) = ∆y/∆x

Using two points on the line, (0, 4) and (1, 9),

Slope (m) = (9 - 4) / (1 - 0)

Slope (m) = 5/1

Slope (m) = 5

✔️Slope of function 2:

Slope (m) = ∆y/∆x

Using the coordinates of any two given pairs form the table, (0, 1) and (1, -3):

Slope (m) = (-3 - 1) / (1 - 0)

Slope (m) = -4/1

Slope (m) = -4

✔️Slope of Function 3:

The function is given in the slope-intercept form, y = mx + b

m = slope

The function y = 2x - 5, therefore has a slope (m) of 2

Slope = 2

✔️Slope of Function 4:

Slope (m) = -1

✅Thus, the functions that has slopes less than -2 are:

Function 2: slope = -4

Function 1, 3, and 4 all have slopes that are greater than -2

Answer:

RQ = 10

Step-by-step explanation:

When two triangles are similar, the ratio of their corresponding sides are equal;

Thus, we have it that;

QP/RQ = BC/AB

12/RQ = 36/30

RQ = 12 * 30/36 = 10
