How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
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
What’s the answer to this equation?
Answer:
Infinite solutions
Step-by-step explanation:
-(-x + 1) = x - 1
x - 1 = x - 1
This is my last question. Please help me!
Okay so first you want to simplify the given equation (7x+3y)(7x-3y)
in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2
Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2
Its as easy as pie!

if u answer this ima be hella impresed
Honest people would tell other people what they think honestly. And honestly, I don't know how to answer your question :( Honestly, I feel like I don't deserve to answer this question if I can't come up with an honest answer. I don't know, maybe I come back to this question another day when I'm older and wiser, and have an answer that will impress you with my honesty. But for now, honestly, I feel like I have failed this user.

Express the product of 300 and 500 in scientific notation.
Answer:
It should be [tex]15*10^{4}[/tex].
Step-by-step explanation:
[tex]300=3*10^{2}\\500=5*10^{2}\\\\300*500=(3*10^{2})*(5*10^{2})=(3*5)*10^{(2+2)}=15*10^{4}=1.5*10^{5}[/tex]
Answer: 1.5 x 10^5
Step-by-step explanation:
The first step is to re-arrange the factors like this :
5 x 3 x 10^2 x 10^2
Since
5 x 3 = 15
and the index law
10^a x 10^b = 10^a + ^b
gives us
10^2 x 10^2 = 10^2 + ^2 = 10^4
then we can rewrite the product like this :
5 x 3 x 10^2 x 10^2 = 15 x 10^4
Finally, we need to convert this into scientific notation :
15 x 10^4 = 1.5 x 10^5
So the final answer is
1.5 x 10^5

4. A plane at an altitude of 10,000 feet is approaching an island. At a given moment, the angle of depression to the near side of the island is 56° and the angle of depression to the far side of the island is 24º. Determine the length of the island, in miles, as seen in the figure below. (8 points) Show all of your work, using correct mathematical notation, on a different piece of paper Answer the question in a complete sentence. Clearly define all of your variables. You may define your variables by labeling the picture or drawing appropriately. The abbreviations opp, adj, and hyp may not be used as variables.
Answer:
The angle of depression calculator. How to find the angle of depression?
Since we now know what the angle of depression is, let's learn how to find it! We can determine the angle of depression using surveying equipment like an engineer's transit or a clinometer. These devices are optical instruments that have angle-measurement features and can instantly give us the angle that we need. However, we can also use mathematics to find the angle of depression. But first, we need to know two distances: the horizontal distance between the viewer and the object, and their vertical distance, as shown in the illustration below:
A basket ball player attempts 15 baskets in a game . He makes 9 of the attemps what is the ratio
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!

Determine if the triples below are right triangles.
Port A: 290, 696, 750
Port B: 514, 684, 855
part C: 450, 1080, 1170
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

This is a similar triangle. Please find the missing length. (?)
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

Which functions have graphs with slopes less than -2?
(Check all that apply.)
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
El Señor Carlos Villa quién Pide al Banco Azteca un crédito de $110000 sobre una tasa del 10% al año su cantidad a pagar será de
Responder:
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
