Pablo had 638 grams of cashew nuts and 594 grams of peanuts. He mixed the nuts and packed them into 7 packets. Each packet of nuts had a mass of 120 grams. How many grams of nuts did Pablo have left?
Answers
The nuts left with Pablo after using 840 g of nuts to make 7 packets is 392 g.
We are given that:
Pablo has
Cashew nuts = 638 g
Peanuts = 594 g
He now has mixed the nuts.
Total amount of nuts will be calculated by using addition.
Total amount of nuts = T = 638 g + 594 g
T = 1232 g
He has made a total of 7 packets and in each packet, he has put 120 g of nuts.
Total nuts used = 7 × 120 g = 840 g
Nuts left with Pablo = 1232 g - 840 g
Nuts left = 392 g
Therefore, we get that the nuts left with Pablo after using 840 g of nuts to make 7 packets is 392 g.

Use the figure below to list the slopes m₁, m₂, m3, and m4 in order of decreasing size.
Answers
the order, from largest to lowest, is:
Purple line, Green line, Blue line, Red line.
How to list the slopes in decreasing order?
A linear equation written in the slope-intercept form is:
y = a*x + b
Such that a is the slope, and it tells us how fast the function changes.
Positive slopes mean that the lines go upwards (purple or green in this case)
Negative slopes mean that the lines go downwards (blue or red in this case)
As larger is the slope, more steep is the function (for the cases with positive slope, is the opposite for negative slopes).
Then the order, from largest to lowest, is:
Purple line, Green line, Blue line, Red line. (y can't see the subindices of the slopes in the lines, so I only can identify the colors).

The value is XY : QR = 1 : 3
What is similarity?Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal.
Given: Δ PQR, Point X and Y are on sides PQ and PR,
XY || QR
In Δ PQR
∠PXY = ∠PQR ( Corresponding angles )
∠PYX = ∠PRQ ( Corresponding angles )
Now, In ΔPQR and ΔAXY
∠P = ∠P ( common )
∠PXY = ∠PQR ( given )
∠PYX = ∠PRQ ( given )
ΔPQR ~ ΔAXY by AAA similarity Criteria.
We get,
PX/ XQ = PY/PR = XY/QR
PX/ XQ = PY/PR = 1/2
PQ = 1 + 2 = 3
PX/ PQ=1/3
hence, the ratio is XY : QR = 1 : 3

In 1970, it was 45.4 sec. Let R(t)=the record in the race and t= the number of years since 1920.
a) Find a linear function that fits the data.
b) Use the function in (a) to predict the record in 2003 and in 2006.
c) Find the year when the record will be sec.
Answers
The year will be 2018, the predicted record of 43.74
1920, the record for a certain race was 45.9 sec.
In 1950, it was 45.0 sec.
Let R(t)= the record in the race and t= the number of years since 1920.
How to calculate slope
The equation of slope of any line can be calculated using the following formula, m = rise/run = tanθ = Δy/Δx = (y2 - y1)/(x2 - x1) where, m is the slope. Δy is the change in y-coordinates.
slope = (45-45.9)/30 = -0.9/30 = -0.03
EQUATION:
R(t)= -0.03t + 45.9
b) The predicted record for 2003
t = 83 in 2003
R(83) = -0.03*83 + 45.9
R(83) = 43.41
The predicted record for 2006
t = 86 in 2006
R(86) = -0.03*86 + 45.9
R(86) = 43.32
C) Solve for t
-.02t + 45.7 = 43.74
-.02t = 43.74 - 45.7
-.02t = -1.96
t = +98
1920 + 98 = 2018, the predicted record of 43.74
This type of equations are called linear equations

A Global Positioning System satellite orbits d = 13,500 miles above Earth's surface (see figure). Find the angle of depression (in degrees) from the satellite to the horizon. Assume the radius of Earth is 4,000 miles. (Round your answer to two decimal places.)
Answers
Using relations in a right triangle, it is found that the angle of depression from the satellite to the horizon is of 89.35º.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.First, we consider that:
The opposite side to the internal angle at the satellite is of 4000 mi.The hypotenuse is of 4000 mi + d mi = 17500 mi.Hence the sine of the angle is given as follows:
sin(θ) = 4000/175000
θ = arcsin(4000/175000)
θ = 1.31º.
Twice the angle of depression x and θ are supplementary, hence:
2x + 1.31 = 180
2x = 178.69.
x = 178.69/2
x = 89.35º.
The angle of depression from the satellite to the horizon is of 89.35º.

Answers
The ending balance of retained earnings for Sultan Inc. as at December 31, 2021 is $40,100
What is the retained earnings at the end of 2020?
The retained earnings at the end of 2020 is the net earnings for 2020 minus the dividends paid in 2020 , in other words, the 2020 ending balance of retained earnings are computed as shown below:
retained earnings for 2020=$31,000-$14,200
retained earnings for 2020=$16,800
However, we need to determine additional retained earnings in 2021 which is also ascertained as net earnings minus dividends paid
additional retained earnings in 2021=$42,000-$18,700
additional retained earnings in 2021=$23,300
the ending balance of retained earnings for Sultan Inc. as at December 31, 2021=2021 balance of retained earnings+ additional retained earnings in 2021
the ending balance of retained earnings for Sultan Inc. as at December 31, 2021=$16,800+$23,300

If PR = 24 and RS = 11, what is PS?
PS = 42
PS = 13
PS = 27
PS = 35
Answers
The length of the line segment PS will be 35 units when PR is 24 units and RS is 11 units.
We are given the length of two line segments as:
PR = 24 units
RS = 11 units
Now, we need to find the length of PS.
We will use the operation of addition here as PS will be equal to the sum of PR and RS. Addition refers to the basic operation of mathematics that is used to simplify and evaluate an expression or an equation.
So, we get that:
PS = PR + RS
Substituting the values, we get that:
PS = 24 units + 11 units
PS = 35 units
Therefore, we get that, the length of the line segment PS will be 35 units when PR is 24 units and RS is 11 units.

Answer: 2 pairs
Step-by-step explanation: You can tell which angles are congruent based on the curved markings. Pairs of congruent angles have matching markings. Since two of the angles are congruent to each other, we can assume that the third angles on the triangles are also congruent to each other, but it is not marked as such. So, there are only two marked pairs of congruent angles.
