34 – 16 = ?
Tens Ones
Answer:
1 ten
8 ones
Step-by-step explanation:
34 - 16 is 18. Therefore, you need 1 ten and 8 ones to make the number 18.
In 13 liters of 18% salty solution we add 402g of salt. What is the concentration of the new mixture?
9514 1404 393
Answer:
21.1%
Step-by-step explanation:
Adding 402 g of salt to a solution whose volume is 130 × 100 mL will increase the concentration by (402/130)%, or about 3.09%.
When the concentration of 18% has 3.09% added to it, the concentration of the new mixture is about 21.1%.
_____
Additional comment
We understand the units of concentration used here to be (1 g)/(100 mL) = 1%. These units are often used for a solution with a dissolved solid.
what is -1/2(7z+4)+1/5(5z-16)
Answer:
[tex] - \frac{1}{10} \times (25z + 52)[/tex]
Step-by-step explanation:
-1/2 (7z + 4) + 1/5 (5z - 16)
-1/10 × (5(7z + 4) - 2 (5z - 16))
-1/10 × (35z + 20 - 10z + 32)
= -1/10 × (25z + 52)

Step-by-step explanation:
Given: ΔABC, CM⊥AB, BC = 5, AB = 7, CA = 4√2
Find: CM
Step-by-step explanation:
first finding the area of the triangle by Heron's formula.
s=(a+b+c)/2, a=BC=5 unit, b=AC= 4√2unit, c=AB=7unit.
s=(5+4√2+7)/2 = (12+4√2)/2 =2( 6+2√2 )/2 = 6+2√2 unit .
Now, the Heron's formula : √s(s-a)(s-b)(s-c)
> √ (6+2√2)[(6+2√2)-5][(6+2√2)-4√2][(6+2√2)-7]
we have use √2's value ; 1.414 to simplify.
please simplify it with the help of calculator or doin it in a copy, because it is very difficult to share the full calculation. AFTER CALCULATION,
> √196.0000 > 14(units)².
Now, we know that the area of triangle is 14(units)². and another formula of finding the area of triangle is ½(base)(height). let the height be h.
Area = ½(base)(height)
=>14= ½(7)h. (after cross multiplication)
=>(14×2)/7=h. (after cancellation)
=>2×2=h.
=> 4units = h.
Therefore, CM that is the height is 4units.
I have every time written units because the unit is not given or you have not posted if given in the question you will write that unit only like cm or m anything like that.

How to solve and simplify to the smallest fraction
Answer:
7/12
Step-by-step explanation:
When you multiply fractions you just multiply across. 7*6 = 42 and 8*9 = 72. The both of these numbers can be divided by six so 42/6 = 7 as the numerator. 72/6 = 12 for the denominator. 7/12 is the answer.
Given deductions for this week: Federal Tax $61.34, FICA $52.05, and State $7.92 What is the annual Federal Tax deduction? $6,308.12 $3,189.68 $3,152.06 $1,594.84
The annual Federal Tax deduction is $ 3,189.68.
Given that the deductions for the week were: Federal Tax $ 61.34, FICA $ 52.05, and State $ 7.92; To determine what is the annual Federal Tax deduction, the following calculation must be performed:
Federal Tax deduction x number of weeks per year = X $ 61.34 x 52 = X $3,189.68 = X
Therefore, the annual Federal Tax deduction is $ 3,189.68.

A point lies to the left of the y-axis
and below the x-axis. What can you conclude about the coordinates
of the point
The point lie in quadrant 3 and both x and y coordinates of the point will be negative.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
It is given that point lies to the left of the y-axis and below the x-axis
For an example of a point in quadrant 3 and left of the y axis and below the x axis would be (-3,-3).
Therefore, the values of tangent and cotangent will be positive, while the values of sin, cosine, cosecant, and secant will be negative if trigonometric values of triangles are used in quadrant 3.
The point lie in quadrant 3 and both x and y coordinates of the point will be negative.

For the function, find the point(s) on the graph at which the tangent line has slope 2.
y=-0.025x^2 +4x
If y = -0.025x^2 + 4x, then
y' = -0.05x + 4
Set y' = 2:
2 = -0.05x + 4
-2 = -0.05x
40 = x
Go back to y to find the point:
y = -0.025(40)^2 + 4(40) = 120
So the point (40, 120) on y = -0.025x^2 + 4x will have tangent line with a slope of 2.

Un grupo de estudiantes tiene como proyecto final determinar el grado de aceptación de las amas de casa de cierto sector de la ciudad hacia un nuevo detergente. De los resultados obtenidos se pudo establecer que aproximadamente 95% de las amas de casa prefieren un detergente en presentación de 500 gramos, contra el mismo producto, pero en una presentación de 1500 gramos. Se lleva a cabo un sondeo sobre la predilección del tipo de presentación del detergente entre 20 amas de casa seleccionadas al azar y donde las respuestas dadas son independientes. Si los estudiantes están interesados en calcular la probabilidad de que exactamente 5 de las amas de casa prefieran la presentación de 1500 gramos, el valor que obtienen es
Usando la distribución binomial, se encuentra que hay una probabilidad de 0.0022 = 0.22% que exactamente 5 de las amas de casa prefieran la presentación de 1500 gramos.
Para cada estudiante, solo hay dos resultados posibles. O prefieren la presentación de 500 gramos, o prefieren la de 1500 gramos. La decisión de cada estudiante es independiente de otros estudiantes, o que implica que se usa la distribuición binomial.
Distribuición binomial.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Los parámetros son :
n es el número de ensayos. x es la probabilidad de éxito en una sola prueba. p es la probabilidad de éxito en un solo ensayo.

Answer:
We draw a number line 0.4 to 1.6 showing at least 5 values of decimal to =1
This way 1 can be centralised in such number line to compare scale from 1.
Here attached shows 6 values 0.4 to 1.6
The open circle is 1 and the arrow is M showing its direction and value.
When the variable is on both sides of the equation, it must be isolated on one side, and it doesn't matter which
side.
O True
O False
Answer:
The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number.
