a. Find the perimeter of the figure of the following is true:
a=x+7
b=2x+2
c=8x
d=x+10
b. What is the perimeter of the figure in part (a) if x=4?
Answer:
a=11, b=10, c=32, and d=14.
Step-by-step explanation:
Answer:
67 units
Step-by-step explanation:
Perimeter of a shape is the sum of all sides.
Perimeter = a + b + c + d
= x +7 + 2x + 2 + 8x + x +10
= x + 2x + 8x + x +7 + 2 + 10
Combine like terms,
= 12x + 19
Now, substitute x = 4 in the above expression,
= 12*4 + 19
= 48 + 19
= 67

The elevation of a small submarine changes by-mile after each exploration. After
how many explorations will the submarine's elevation have changed by -1 miles?
The submarine's elevation would have changed by -3/2 mile after 4 explorations.
What is elevation?An elevation is a view of a three-dimensional shape from the side or the front. "Rise over run" is an easy-to-remember equation for calculating a change in elevation as a decimal, which means the rise (the change in vertical distance) divided by the run (the change in horizontal distance).So, to find how many explorations will the submarine's elevation has changed by -1 miles:
After each exploration, the submarine's elevation changes by -3/8 mile.To calculate the number of explorations required to change the submarine's elevation by -3/2 mile, divide -3/2 mile by the number of miles the submarine's elevation changes per exploration (that is, -3/8 mile).Then,
-3/2 miles ÷ -3/8 mile-3/2 ÷ -3/8 mile-3/2 × -3/8 mile24/64Therefore, the submarine's elevation would have changed by -3/2 mile after 4 explorations.

By using the trigonometric function of cosine, we conclude that the length of the hypotenuse is approximately equal to 7.2 units.
How to determine the length of the hypotenuse by trigonometric functions
Right triangles are triangles such that one of its internal angles is a right triangle. Fundamentally, trigonometric functions are relationships between two distinct sides of a right triangle.
The picture show that the length of one leg and the measure of the angle between that leg and the hypotenuse are known, but the length of the hypotenuse does not. By using concepts of trigonometric functions, we can find the length of the hypotenuse by using the cosine function:
cos θ = s / x
cos 33° = 6 / x
x = 6 / cos 33°
x = 6 / 0.839
x ≈ 7.154
The length of the hypotenuse is approximately equal to 7.2 units.

What is Uncertainty?
The range of potential values between which the genuine value of both the measurement can be found is referred to as uncertainty in this context.a) A basket's capacity for eggs:
The measurement that is precise and free from uncertainty is the number of counting objects. Consequently, we are able to precisely count the eggs in a basket.

Given that no two bananas are the same size and therefore have different masses, it is uncertain to determine the mass of a dozen bananas. This is true for the computation of the mass of any object.
c) The iron block's mass
Because no two pieces of iron in an iron block are the same size, it is difficult to determine the mass of an iron block.

Due to the fact that gasoline is indeed a gas molecule and is volatile, it is difficult to calculate how many gallons are required to fill an automobile's gas tank.

How to solve a system of linear equation behind a weight system
In this question we find a case of abstract thinking, in which we find a weight system at equilibrium. There are the following variables below:
x - Weight of a red circle.
y - Weight of a purple cross.
r - Weight of an orange star.
u - Weight of a dark blue square.
v - Weight of a yellow rhombus.
w - Weight of a green trapezoid.
z - Weight of a light blue triangle.
And the resulting system of linear equations is:
x + y = 24 (1)
y + v = 12 (2)
u = 6 (3)
2 · r = 6 (4)
1.5 · v + 2 · u = 24 (5)

A falcon flies 800,000 meters in 4 hours. Use the formula d = rt, where d represents distance, r represents rate, and t represents time, to answer the following questions. Show your work.
Part A: Rearrange the distance formula, d = rt, to solve for rate. (3 points)
Part B: Find the falcon's rate in meters per hour. (4 points)
Part C: Rearrange the distance formula, d = rt, to solve for time. (3 points)
Please I really need this right now please
A) The rearranged formula is:
r = d/t
B) Using the above formula we can see that the rate is 25,000 m/h.
C) Here we have the linear equation:
d = (25,000 m/h)*t
How to solve the formula for the rate?Here we need to use the formula:
distance = rate*time.
To solve this formula for the rate, we need to divide both sides by the time, so we will get:
rate = distance/time.
Writing this with the given variables:
r = d/t.
b) Now we know that the distance is 800,000 meters and the time is 4 hours, then the rate will be:
r = 100,000m/4h = 25,000 m/h
The rate is 25,000 meters per hour.
c) Now we wil get the linear equation:
d = r*t
d = (25,000 m/h)*t
This linear equation gives the distance traveled in a time t.

#SPJ1
Part A:
Rearrange the distance formula, d = rt, to solve for rate. The distance formula is given by d = rt, where d is the distance traveled, r is the rate at which the distance is being traveled, and t is the time taken to travel the distance.
To solve for rate, we can rearrange the formula as follows: d = rt d/t = r [dividing both sides by t] r = d/t
Therefore, the formula for rate is r = d/t.
Part B: Find the falcon's rate in meters per hour. Given that the falcon flies 800,000 meters in 4 hours, we can use the formula for rate to find its speed. r = d/t r = 800,000/4 r = 200,000 meters per hour.
Therefore, the falcon's rate is 200,000 meters per hour.
Part C: Rearrange the distance formula, d = rt, to solve for time. To solve for time, we can rearrange the formula as follows: d = rt t = d/r [dividing both sides by r]
Therefore, the formula for time is t = d/r.

The required value of x in the proportion of the line is 9.
Given that,
B is located between points A and C.
AB= x + 2; BC = 2x + 7 and AC = 36
To determine the value of x in the proportion of line.
A line is a straight curve connecting two points or more showing the shortest distance between initial and final points.
Here,
B is the point lies between A and C on line segment AC
So,
AC = AB + BC
AB + BC = 36
x + 2 + 2x + 7 = 36
3x + 9 = 36
3x = 27
x = 27 / 3
x = 9
Thus, the required value of x in the proportion of the line is 9.

What do math extrema mean?
Any point in calculus when the value of a function is either the highest (a maximum) or the lowest (a minimum) (a minimum). There are maxima and minima that are both absolute and relative (or local).Identify every stationary point. The solution set that results from setting the partial first derivatives to zero includes those points.Look at each stationary point's personality. This is done explicitly in the first case by looking at the eigenvalues of the second derivative matrix. The fact that there are quick formulas for this if there are just two variables, is superior.Higher order derivatives must be investigated in the improbable event that the results of the second derivative matrix study are ambiguous.

two lines are cut by a transversal such that a pair of alternate interior angles are right angles. are the two lines parallel? explain
Two lines are cut by a transversal such that a pair of alternate interior angles are right angles, then the two lines are parallel.
Following are the condition that satisfies to make two lines parallel,
When a transversal cuts two lines so that their opposing exterior angles coincide, the lines are said to be parallel. When a transversal cuts two lines so that their subsequent interior angles are supplementary, the lines are said to be parallel. Two lines are parallel to one another if they are both parallel to the same line. Parallel lines are those that never cross and always lie at the same distance apart. Both lines need to be parallel (in the same plane). The symbol for parallel lines is written as two thin parallel lines in geometry shorthand, as ∥. A transversal that crosses two parallel lines creates alternate interior angles. They form two pairs (four total angles) of alternating internal angles since they are situated between the two parallel lines but on different sides of the transversal.Learn to know more about parallel lines on
