Answers

Solving a system of equations we can see that:

She needs to use 56 oz of the 85% solution.She needs to use 14 oz of the 60% solution.How many ounces of each solution should she use?

We can use the variables:

x = mass of the 60% solution.

y = mass of the 85% solution.

We can write a system of equations.

x + y = 70

x*0.6 + y*0.85 = 70*0.8

We can isolate x on the first equation to get:

x = 70 - y

Replace that in the other one:

(70 - y)*0.6 + y*0.85 = 70*0.8

Now we can solve this for y.

y*0.25 = 70*0.8 - 70*0.6

y = 14/0.25 = 56

Then he needs to use 56 ounces of the 85% solution, and 14 ounces of the 60% solution.

The relationship in the figure is a function because each input has only one output to which they are linked

What is a function?

A function is a definition or rule that maps each element in a set of input values to exactly one element in a set output values.

The data in the sets can be presented as follows;

x  \({}\)               f(x)

-1 \({}\)      →         2

8\({}\)         →        3

The above table indicates that each x-value has only one f(x) value, which indicates that the relationship s a function. The relationship is still a function with the presence of an f(x) value, 2, having two x values, -1 and 0, as the condition satisfies the definition of a function.

Since y is directly proportional to x³, then y = kx³, where k is a constant.

When x = 10, y = 250,

The attached graph represents the graph of the function y = h(2x) + 1

How to draw the graph?

The points on the graph of y= h(x) are:

(-1,-2), (-2,-4), (0,0), (2,-1), (4,-2)

Using the above ordered pairs, the points on y = h(2x) + 1 are:

When x = -1, h(2x) = h(-2) = -4

So, we have:

y = -4 + 1 = -3

When x = -2, h(2x) = h(-4) = -8

So, we have:

y = -8 + 1 = -7

When x = 0, h(2x) = h(0) = 0

So, we have:

y = 0 + 1 = 1

When x = 2, h(2x) = h(4) = -2

So, we have:

y = -2 + 1 = -1

When x = 4, h(2x) = h(8) = -4

So, we have:

y = -4 + 1 = -3

So, the points on the graph of y = h(2x) + 1 are:

(-2,-7), (-1,-3),  (0,1), (2,-1), (4,-3)

Answers

The  largest amount of money they can borrow is $$276.268.65

How to calculate the largest amount?

The main formula used in this problem is the Present Value of an annuity Formula:

P = R[1-(1+i)⁻ⁿ]/i

Where;

P: present value (the mortgage value)R: periodic paymentt: time (in years)r: annual interest ratem: number of compounding per yeari=r/m      (rate per period)n=mt      the total number of payments

The maximal monthly payment that Bethany and Samuel can afford is $1,500.

The best interest rate is %5.1 annually, and they want to sign a 30-year mortgage.

This implies that

R=1,500

t=30

r=%5.1 = 5.1 /100 = 0.051

m=12, because they make the payments monthly

i=r/m=0.051/12=0.00425

n=mt = 12*30=360

That is,

i) they will make 360 monthly payments,

ii) the largest amount of money they can borrow can be found using the formula:

P = R[1-(1+i)⁻ⁿ]/i

Substituting the known values:

P = 1500[1-(1+0.00425)⁻³⁶⁰]/0.00425

How to Find angles Mark by Letters?The lines are parallel.

Answers

You know that the lines are parallel and they are intersected by a transversal.

Then, it is important to remember the following pair of angles:

1. Vertical angles are congruent. They share the same vertex.

2. Corresponding angles are congruent. They are located on the same side of the transversal. One angle is exterior and the other angle is interior. They are non-adjacent angles.

In this case, you can identify that the angle "b" and the angle that measures 130 degrees are Corresponding angles. Then:

\(b=130\degree\)

You can also identify that the angle "b" and the angle "c" are Vertical angles. Then:

Question 3 (1 point)
Karl wants to find the width RQ of a river. He starts at point R, and walks
perpendicular along the edge of the river 42 ft and marks point S. He then walks 28
ft further and marks point T. He turns 90° and walks until his location (point U), point
S, and point Q are collinear. Suppose TU= 68 ft. What is the width of the river in
feet?

Answers

The width RQ of the river is approximately 61.98 ft.

To find the width RQ of the river, we can use the properties of perpendicular lines and collinearity.

Given that Karl starts at point R and walks perpendicular along the edge of the river 42 ft to point S, we can draw a line segment RS of length 42 ft.

From point S, Karl walks 28 ft further to point T. We can draw another line segment ST of length 28 ft.

Now, Karl turns 90° from point T and walks until his location (point U), point S, and point Q are collinear. Let's denote the length of this line segment as UQ.

From the given information, we know that TU = 68 ft.

Since U, S, and Q are collinear, we can form a right triangle by connecting UQ and US.

The length of UQ can be found using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, we have:

UQ² = TU² - US²

UQ² = 68² - 28²

UQ² = 4624 - 784

UQ² = 3840

Taking the square root of both sides, we have:

UQ = √3840

UQ ≈ 61.98 ft

Therefore, the width RQ of the river is approximately 61.98 ft.

Note: It's important to keep in mind that this solution assumes the river is a straight line and that Karl's path is perpendicular to the river's edge. In reality, the river's edge may not be perfectly straight, and the path Karl walks may not be exactly perpendicular.

we know the slope is 3 so m=3

so
3= 3(-2) + c
c=9
thus, y=3x+ 9
Answer: y = 3x + 11

Explanation:
y = kx+m is the equation of a line. The coefficient of x is the slope i.e 3. So we know that a part of the equation is y = 3x + m.

How to find M?
Well, we already have a point on the equation. Meaning we already have an x and a y. -2 = x and 5 = y.

The equation then becomes 5 = (3 x -2) + m.

Solve for m and the answer will be m = 11.

Now we have both m and K meaning that the whole equation is solved and it’s y = 3x + 11

Answers

Answer:

Time taken is 0.897 sec and distance traveled is 56.36 mm

Step-by-step explanation:

It is given radius of the coin r = 10 mm

Angle measure \(\theta =360^{\circ}\)

In radian it will be equal to

\(\theta =360^{\circ}\times \frac{\pi }{180}\)

\(=2\pi =6.28radian\)

Angular velocity = 78 rev/sec

It is known that \(\theta =\alpha t\)

Therefore \(6.28=7\times t\)

t = 0.897 sec

Now distance traveled will be equal to

\(d=2\pi r\times t\)

\(=20\times 3.14\times 0.897\)

Write an equation of the line that passes through (0, -1) and is perpendicular to the line y = 1/9x + 2

An equation of the perpendicular line is y =

Answers

The equation of the perpendicular line passing through (0, -1) is y = -9x - 1.

To find the equation of a line that is perpendicular to the given line y = (1/9)x + 2 and passes through the point (0, -1), we can use the fact that perpendicular lines have slopes that are negative reciprocals of each other.

The given line has a slope of 1/9. To find the slope of the perpendicular line, we take the negative reciprocal of 1/9, which is -9.

Using the slope-intercept form of a linear equation, y = mx + b, where m represents the slope and b represents the y-intercept, we can substitute the slope and the coordinates of the given point (0, -1) into the equation.

y = -9x + b

Since the line passes through the point (0, -1), we can substitute the x-coordinate as 0 and the y-coordinate as -1 into the equation:

-1 = -9(0) + b

-1 = b

Therefore, the y-intercept (b) of the perpendicular line is -1.

Putting it all together, the equation of the line that passes through (0, -1) and is perpendicular to y = (1/9)x + 2 is:

y = -9x - 1

Step-by-step explanation:

You want the angle opposite the side of length 7 in the triangle with other sides of lengths 4 and 8.

Law of Cosines

The law of cosines relates the angles of a triangle to the side lengths. For triangle ABC with opposite sides a, b, c, the relation is ...

  c² = a² +b² -2ab·cos(C)

Application

Solving for angle C, we have ...

  cos(C) = (a² +b² -c²)/(2ab)

  C = arccos((a² +b² -c²)/(2ab))

In this triangle, that means ...

  C = arccos((4² +8² -7²)/(2·4·8)) = arccos(31/64)

  C ≈ 61.03°

The angle of interest is about 61.03°.
