Therefore , the solution of the given problem of angles comes out to be

r1 (1) = r2.

An angle is a form in Euclidean geometry composed of two rays, called the hook's flanks, that converge at a point in the middle known as the vertex of the angle. In the plane that they are located, two ray may combine to make an angle. The collision of two planes also produces an angle. Dihedral angles are what we call them.

Here,

Make the pair of elements

r1 (t) = r2 (s) t = 7 - s

or

t + s = 7 equal to one another.

35 + t2 = s2, or 35 - t2 = 4, or s2 - t2 = 35

Step 2: Using the t value from equation 1, simplify equation 3.

35 + ( 7 - s ) ( 7 - s )

2 = s2 14s = 84 s = 6 and t = 1 are equivalent to.

Step 3: In formulas (1), (2), and, substitute these values of "t" and "s"

The  718.85 < x inequality says that : He must print 719 photos or more.

Inequality:

In mathematics, an inequality is a relationship in which two numbers or other mathematical expressions compare unequal. Most commonly used to compare two numbers on the number line based on size. There are several notations used to represent various types of inequalities.

Given,

In the question:

Rick bought a photo printer and supplies for $186. 90, which will allow him to print photos for $0. 29 each.

and, A photo store charges $0. 55 to print each photo.

To find the how many photos must Rick print before his total cost is less than getting prints made at the photo store?

Now,

According to the question:

Let the photos be x

Rick bought a photo printer be $186.90

A photo store charges $0. 55 to print each photo.

The question is based on inequality:

Photo Printer <  photo store

1.86.90 + 0.29x <  0.55x

            - 0.29x     - 0.29x

______________________

           1.86.90    < 0.26x

If he left home 50 minutes before the class started he was 53.7 minutes late for his class.

Given that,

Speed of the bike = 16 feet per second = 10.9091 miles/hour

Distance from home to bus stop = 5 miles

Total time taken to reach bus stop = distance/ speed = 5 miles/10.9091 miles/hour= 0.458 hours = 27.5 minutes

Then, speed of the bus = 25 miles per hour

Distance from bus stop to campus = 25 miles

Total time taken to reach campus = distance/ speed = 25 miles/25 miles/hour= 1 hour= 60 minutes

Then, speed of the bike = 16 feet per second = 10.9091 miles/hour

Distance from campus to bike rack = 480 yards =  0.2727 miles

Total time taken to reach bike rack = distance/ speed = 0.2727 miles/ 10.9091 miles/hour= 0.249 hour= 15 minutes (approximately)

Then, the Speed of walking = 2.5 miles per hour

Distance from bike rack to class = 250 feet =  0.047 miles

Total time taken to reach class = distance/ speed = 0.047 miles/ 2.5 miles/hour= 0.0188 hour= 1.2 minutes (approximately)

Thus, total time taken to reach class = 27.5 minutes+60 minutes+15 minutes+1.2 minutes = 103.7 minutes
Therefore, If he left home 50 minutes before the class started he was 53.7 minutes late for his class.

Step-by-step explanation: 1/X + 1/X+2 = 11/60. THEN DO ALGEBRA THAT TOOK ME FOREVER IT WAS SO HARD.

Answer:

See attachment.

Step-by-step explanation:

If CD and MB are parallel, triangle CDE is similar to triangle MBE.

In similar triangles, corresponding sides are always in the same ratio.

[tex]\implies \sf CD:MB=DE:BE=EC:EM[/tex]

From inspection of the given diagram, EM is approximately 0.35 times the length of EC.  Therefore, let EC = 10 and EM = 3.5.

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Therefore, let CD = 7 and let DE = 12.

Substitute these values into the created ratio equation:

[tex]\implies \sf 7:MB=12:BE=10:3.5[/tex]

[tex]\implies \sf \dfrac{7}{MB}=\dfrac{12}{BE}=\dfrac{10}{3.5}[/tex]

Calculate BE:

[tex]\implies \sf \dfrac{12}{BE}=\dfrac{10}{3.5}[/tex]

[tex]\implies \sf \dfrac{12 \cdot 3.5}{10}=BE[/tex]

[tex]\implies \sf BE=4.2[/tex]

Calculate MB:

[tex]\implies \sf \dfrac{7}{MB}=\dfrac{10}{3.5}[/tex]

[tex]\implies \sf \dfrac{7 \cdot 3.5}{10}=MB[/tex]

[tex]\implies \sf MB=2.45[/tex]

Therefore:

[tex]\implies \sf CM=EC-EM[/tex]

[tex]\implies \sf CM=10-3.5[/tex]

[tex]\implies \sf CM=6.5[/tex]

[tex]\implies \sf DB=DE-BE[/tex]

[tex]\implies \sf DB=12-4.2[/tex]

[tex]\implies \sf DB=7.8[/tex]

The absolute value is also called a modulus.

The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign, also describes the distance from zero that a number is on the number line, without considering direction.

It is represented as |a|, which defines the magnitude of any integer ‘a’.

Absolute value is a term used in mathematics to indicate the distance of a point or number from the origin (zero point) of a number line or coordinate system.

it defines removing any negative sign in front of a number and thinking of all numbers as positive.

When x itself is negative (x<0), then its absolute value is necessarily positive

Answer: total cost of an international call with a duration of 10 minutes is 5.70 dollars.

Step-by-step explanation:

The expression 2.20 +0.35x represents the total cost of an international call in dollars, as a function of the duration x in minutes.

It is composed of two parts:

The first part, 2.20$, represents the fixed cost of making an international call. This cost does not change regardless of the duration of the call.

The second part, 0.35x$, represents the variable cost of the call, which is based on the duration of the call in minutes. This cost increases with the duration of the call.

When x=10, it means the duration of the call is 10 minutes, so the variable cost of the call would be 0.35*10 = 3.5$

Therefore, the total cost of the international call with a duration of 10 minutes is 2.20 + 3.5 = 5.7$

It's important to notice that this equation represents the total cost of the call not just the variable cost, but also the fixed cost.

The percentage of the 90 students on the Springfield High School varsity soccer team who are seniors is 31%.

The percentage is a portion of a whole number or value.

Using percentages is a way of expressing values compared to others in relative terms.

The percentage refers to the ratio, which is obtained as the quotient of a numerator and a denominator, which is then multiplied by 100.

The total number of students on the Springfield High School varsity soccer team = 90

The makeup of the soccer team = freshmen, sophomores, juniors, and seniors

The number of seniors on the soccer team = 28

Answer:

Let's call the number we're trying to find "x".

We know that 35% of x is 77, so we can set up the equation:

0.35x = 77

We also know that 90% of x is 198, so we can set up another equation:

0.9x = 198

We can use the first equation to find the value of x and then substitute that value into the second equation to find 55% of x.

To find x, we divide both sides of the first equation by 0.35:

x = 77 / 0.35 = 220

Now that we know x is 220, we can find 55% of x by multiplying 220 by 0.55:

0.55x = 220 * 0.55 = 121

So 55% of the number is 121.

Answer:

121

Step-by-step explanation:

Because one of the answers is already divisible by 10, allowing us to find 100% of the unknown number, we can first find 10% by dividing the 90% number by 9. 198/9 is 22, meaning 22 is 10% of the number. We can then multiply it by 10 to get 100%, 22(10)=220. Meaning our full number is 220

From here we can simply multiply by our desired percentage, which is 55%. In order to multiply by a percent, you have you divide the percent by 100 to get .55. From there you can do 220*.55= 121. Meaning our answer is 121.
