Answer:
10.5 ≤ y ≤ 14
Step-by-step explanation:
A nickel is worth 5 pennies. Changing over to dollars, it becomes
5/100 = $0.05
A dime is worth dime. Changing over to dollars, it becomes
10/100 = $0.1
Allow x to address the number if nickels.
Allow y to address the quantity of dimes.
He has close to 19 coins. This implies that
x + y ≤ 19
He has no under $1.30 joined. This implies that
0.05x + 0.1y ≥ 1.3
On the off chance that Nolan has 5 nickels, subbing x = 5 into x + y ≤ 19, it becomes
5 + y ≤ 19
y ≤ 19 - 5
y ≤ 14
subbing x = 5 into 0.05x + 0.1y ≥ 1.3, it becomes
0.05 × 5 + 0.1y ≥ 1.3
0.25 + 0.1y ≥ 1.3
0.1y ≥ 1.3 - 0.25
0.1y ≥ 1.05
y ≥ 1.05/0.1
y ≥ 10.5
Along these lines, all potential qualities for the quantity of dimes that he could have would be
10.5 ≤ y ≤ 14

what dose y = ?
Will give brainliest if it is correct!
Answer:
(-5, 1)
Step-by-step explanation:
Eliminate the equal sides of each equation and combine.
[tex] - x - 4 = \frac{3}{5} x + 4[/tex]
Solve − x −4 =35x + 4 for x.
[tex]x = - 5[/tex]
Evaluate y when x = −5.
[tex]y = 1[/tex]
hence, the system of this equation is (-5, 1).

The type of Sequence from [tex]a_1[/tex] = 2 and [tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4 is Arithmetic and recursive.
What is Arithmetic Sequence ?In algebra, an arithmetic sequence is a set of numbers whose every two consecutive terms have the same difference.
An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k. In a geometric sequence, each term rises by dividing by or multiplying by a certain constant k.
For example in the arithmetic sequence 3, 9, 15, 21, 27, the common difference is 6.
Given:
[tex]a_1[/tex] = 2
[tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4
We know that the Arithmetic Sequence is of two forms
Explicit Form : [tex]a_n[/tex] = a+ (n-1)d
and, Recursive form: [tex]a_n[/tex] = [tex]a_{n+1}[/tex] + d
Now, we have [tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4 which is in the form of Recursive.

To solve x^2+5x=0, mia rewrote the equation as x(x+5)=0. Explain how rewriting this equation in factor form enable mai to solve the equation.
The solution to the equation x² + 5x = 0 is x = 0 or x = -5
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
x² + 5x = 0 be equation (1)
Now , on simplifying the equation , we get
On factorizing the equation , we get
Taking the common factor x ,
x ( x + 5 ) = 0
Now , x can take 2 values which will satisfy the given equation
when x = 0 or ( x + 5 ) = 0
when x = 0
Substitute the value of x in the equation , we get
0 ( 0 + 5 ) = 0
0 = 0
The equation is true when x = 0
And ,
when ( x + 5 ) = 0
Subtracting 5 on both sides of the equation , we get
x = -5
when x = -5
-5 ( -5 + 5 ) = 0
-5 x 0 = 0
0 = 0
The equation is true when x = -5
Hence , the solution is 0 , -5

Check if (1,6) is the solution to the system shown below.
Answer:
NO it is not
Step-by-step explanation:
To check that, we will need to substitute the value of each of the coordinates in each of the equations
10x-y = -6
substitute 1 for x and 6 for y
we have this as;
10(1)-6 = 4
Outrightly, we can see that the given point is not a solution to the given system of equations
however, let us confirm for the second
We have this as;
-10(1) + 5(6)
= -10 + 30 = 20
so we can confirm that it does not work for any of the two and our answer is NO
A sphere has a surface area of 803.84 cm^2. What is the volume?
Answer:
V≈2143.03cm³
Step-by-step explanation:
The volume of the sphere is 2143.57 cm³.
What is the surface area of the sphere?A = 4 × π × r², where 'r' is the radius of the sphere.
What is the volume of the sphere?V = (4/3) × π × r³
For given example,
a surface area of the sphere is 803.84 cm^2.
⇒ A = 803.84 cm²
Using the formula of the surface area of the sphere,
⇒ 4πr² = 803.84
⇒ r² = 64
⇒ r = 8 cm
Using the formula of the volume of the sphere,
⇒ V = (4/3) × π × r³
⇒ V = (4/3) × 3.14 × 8³
⇒ V = 2143.57 cm³
Therefore, the volume of the sphere is 2143.57 cm³.

Se 15% de um rebanho bovino são bois e o restante são vacas, qual é o total de cabeças desse rebanho, se há 17.000 vacas?
Responder:
20.000
Explicação passo a passo:
Dado que:
Porcentagem de bois no rebanho = 15%
Percentagem de vacas = (100 - 15)% = 85%
Número de vacas = 17.000
Por isso,
85% = 17.000
15% = x
Multiplicação cruzada
0,85x = 17.000 * 0,15
0,85x = 2550
x = 2550 / 0,85
x = 3000
Número de bois no rebanho = 3000
Portanto, número total de gado no rebanho =
3000 + 17000 = 20.000

Two birds sit at the top of two different trees. The distance between the first bird and a birdwatcher on the ground is 32 feet. The distance between the birdwatcher and the second bird is 45 feet.
A triangle is created from point Bird Watcher, point First Bird, and point Second Bird. Angle First Bird is a right angle, and angle Second Bird measures x degrees.
What is the angle measure, or angle of depression, between this bird and the birdwatcher? Round your answer to the nearest tenth.
35.4°
44.7°
45.3°
54.6°
Answer:
The correct angle is 45.3°
Step-by-step explanation:
Since the opposite side of the angle is 32 feet, and the hypotenuse of the right triangle is 45 feet, you would know that the sine of x° is equivalent to [tex]\frac{32}{45}[/tex]. To find the value of x, take the arcsin of both sides and you'll get that [tex]x = arcsin(\frac{32}{45})[/tex] ⇒ [tex]x[/tex] ≈ 45.3°.
