Marina mixed almonds and walnuts to take on her camping trip. Almonds cost $3.00 per pound and walnuts cost $4.20 per pound. If she ended up with three pounds of a mixture that costs $3.36 per pound, how many pounds of each kind of nut did she use?

Answers

Answer 1

Out of mixture of 3 pounds with cost $3.36 per pound ,pounds each kind of nuts used by Marina are almonds 2.1 and walnuts 0.9 pounds.

As given,

Cost per pound

Almonds=$3.00

Walnuts=$4.20

Total mixture=3 pounds

Cost of mixture=$ 3.36 per pound

Let x amount of almonds and y walnuts Marina use

According to condition,

x +y=3                           __(1)

3x +4.20y =3 ×3.36     __(2)

Multiply 3 to (1) and subtract from (2)

3x +4.20y=10.08

3x +3y= 9

      1.2y=1.08

⇒y=0.9

Substitute y=0.9 in (1),

x=2.1

Therefore, pounds of each kind of nuts used by Marina are almonds 2.1 and walnuts 0.9 pounds.

The volume of dry goods, like apples or peaches, can be measured usings bushels, pecks, and quarts. A bushel contains 4 pecks, and a peck contains 8 quarts.

What is the relationship between number of bushels, b, and the number of quarts, q? If you get stuck, try creating a table.

Answers

The relationship between the number of bushels and the number of quarts is b = 32q.

What is the relationship?

The mathematical operation that would be used to determine the required value is multiplication. Multiplication is the process of determining the product of a number. The sign used to represent multiplication is x.

The equation that represents the relationship between bushel and pecks is: b = 4p

The equation that represents the relationship between a peck and quarts is: p = 8q

In order to determine the relationship between bushels and quarts, substitute for p in the first equation

b = 4(8q)

The multiplication of given fraction is 1 4/5 x 5/6 = 1 1/2

In this question, we have been given an expression 1 4/5 x 5/6

We need solve given mathematical expression.

First we write improper fraction 1 4/5 as proper fraction.

1 4/5 = 9/5

So, given expression becomes,

1 4/5 x 5/6

= 9/5 x 5/6

= 9/6

= 3/2

Now we write 3/2 as improper fraction.

If we divide the 3 by 2,then we will get 1 as quotient and 1 as remainder.

3/2 = 1 1/2

Find the slope of the following lines

Explain how you got the answer

Answers

Answer:

[tex]-\displaystyle\frac{4}{3}[/tex]

Step-by-step explanation:

Slope describes the change in y divided by the change in x.

Solving Using Slope Formula

One way to find slope when you are given 2 points is the slope formula.

Slope = [tex]\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex]

To solve, plug in the x and y-values and simplify. For this question, let (-2, 3) represent the (x₂, y₂) and (1, -1) represent (x₁, y₁).

[tex]\displaystyle\frac{3-(-1)}{-2-1}=-\frac{4}{3}[/tex]

This shows that the slope of this line is -4/3.

Solving Through Counting

When given the graph of a function, you can also count out the slope. Starting from the left point, count the change in y-values and the change in x-values. Remember, when the y-values decrease, the change should be negative. The y-value changes by -4 and the x-value changes by +3.

Since the slope is change in y over change in x, the slope is -4/3.

A traffic helicopter flew directly from Point A to Point B in 8 minutes. Did the helicopter travel faster or slower than the driver? Explain or show your reasoning.

Answers

The time it takes the driver to travel from Point A to Point B is 8 minutes, the same as the helicopter but through a more longer path, such that, we have;

The helicopter travels slower than the driver

How can the speed of the helicopter and the car be compared?

Based on a similar question, the first part required to determine if a driver that drives from Point A to Point B in 8 minutes obeyed the speed limit of 55 miles per hour.

The path of the driver consists of a short path, a bend changing the direction, then a long straight path.

The path of the helicopter is directly from Point A to Point B.

Therefore;

The length of the path of the driver, d1, is longer than that the helicopter, d2, which gives;

d1 > d2

From kinematics, we have;

[tex]Speed = \frac{Distance}{Time} [/tex]

The time taken by the helicopter and the and the driver are equal to 8 minutes, therefore;

[tex] Speed \: of \: the\: driver = \frac{d_1}{8} [/tex]

[tex] Speed \: of \: the \: helicopter = \frac{d_2}{8} [/tex]

[tex] d_1 > d_2 [/tex]

According to the division property of equality, we have;

[tex] \frac{d_1}{8} > \frac{d_2}{8} [/tex]

[tex] \frac{d_2}{8} < \frac{d_1}{8} [/tex]

Therefore;

The speed of the helicopter is lesser than the speed of the driver, which gives;

The measure of angle A and angle B are 31° and 59° respectively.

What are complementary angles?

Complementary angles that sum up to 90 degrees.

We have that;

Angle A + Angle B= 90

9x = 90 - 18

9x = 72

Make 'x the subject

x = 72/ 9

x = 8

Angle A = 3x + 7 = 3(8) + 7 = 31°

Since complementary angles sum up to 90 degrees.

Measure of angle A + Measure of angle B = 90°

Plug in the given values and solve for x.

(3x + 7) + (6x + 11) = 90

Collect like terms
