EXPLANATION

To solve the triangle means to find all sides and angles.

The right triangle has an angle of 38 degrees and an opposite leg of 12 yards

The third angle is 90-38=52°

We use the sine ratio to find the hypotenuse, h.

[tex] \sin(38 \degree) = \frac{opposite}{hypotenuse} [/tex]

[tex] \sin(38 \degree) = \frac{12}{h} [/tex]

[tex]h = \frac{12}{ \sin(38) } [/tex]

[tex]h = 19.49[/tex]

The hypotenuse is 19.49 yards to the nearest hundredth.

We can find the adjacent leg using the cosine ratio.

[tex] \cos(38) = \frac{adjacent}{hypotenuse} [/tex]

[tex]\cos(38) = \frac{a}{19.49} [/tex]

[tex]a = 19.49 \cos(39) [/tex]

[tex]a = 15.36[/tex]

to the nearest hundredth.

The required fraction 40/32 simplifies to 5/4.

Answer:

246.61 feet (rounded to 2 decimal places)

Step-by-step explanation:

We multiply 3/4 with previous minute traveling.

Minute #1: travels 75 feet

Minute #2: travels (3/4)*75 = 56.25 ft

Minute #3: travels (3/4)(56.25) = 42.19 ft

Minute #4: travels (3/4)(42.1875) = 31.64 ft

Minute #5: travels (3/4)(31.64) = 23.73 ft

Minute #6: travels (3/4)(23.73) = 17.80 ft

So, in 6 minutes, the car travels  75 + 56.25 + 42.19 + 31.64 +23.73 + 17.80 = 246.61 feet.

Kyle was 1 minute and 47 seconds faster in a 3-mile race yesterday compared to his normal running time.

Kyle's normal time is 23 minutes and 25 seconds, which is (23 * 60) + 25 = 1405 seconds. Yesterday, Kyle's time was 21 minutes and 38 seconds, which is (21 * 60) + 38 = 1298 seconds.

Now, we subtract the faster time from the normal time: 1405 seconds - 1298 seconds = 107 seconds.

Thus, Kyle was 107 seconds faster yesterday than his normal time. To put it back into minutes and seconds, we divide by 60:  107  \ 60 = 1 minute and 47 seconds.

So, Kyle was 1 minute and 47 seconds faster yesterday.

Answer:

I think Christina caught 23 fish and Sarah caught 8 fish.

Step-by-step explanation:

If I did this right, we have to find the equation to represent this situation. Christina caught one less than 3 times as many as Sarah caught. Since we do not know how many Sarah has, we have to use a variable so let's go with x. One less than 3 times as many would be 3x - 1 because one less means subtracting 1 and 3 times means multiply by three. So we have x for Sarah and 3x - 1 for Christina. We add those together to get x + 3x - 1 = 31 (since they caught 31 fish, the total would be 31). We simplify it down to 4x - 1 = 31. Add one to both sides to cancel it out and we get 4x = 32. Divide by 4 on both sides and we get x = 8. Since Sarah was x, Sarah caught 8 fish. To find Christina we just plug in the 8. 3(8) -1. 3 times 8 is 24 and 24 minus 1 is 23. To check our answers we add 8 and 23 together which comes out to be 31.

Please correct me if I'm wrong! (Now I'm not sure what you mean by a 5D table but if this is right I hope it helps)

The number of fish caught by Sarah = 8

And, The number of fish caught by Christina = 23

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Christina and Sarah went on a fishing trip and caught 31 fish.

Now,

Let number of fish caught by Sarah = x

So, The number of fish caught by Christina = 3x - 1

Here, Christina and Sarah went on a fishing trip and caught 31 fish.

Hence, We get;

⇒ x + (3x - 1) = 31

⇒ 4x - 1 = 31

⇒ 4x = 31 + 1

⇒ 4x = 32

⇒  x= 8

Thus, The number of fish caught by Sarah = x

                                                                  = 8

So, The number of fish caught by Christina = 3x - 1

                                                                   = 3×8 - 1

                                                                   = 23

Step-by-step explanation:

x^2-2x+26=0 can be rewritten by completing the square of x^2-2x, as follows:

x^2-2x+26=0

x^2-2x+ 1  - 1  +26=0 (this 1 comes from halving the coefficient of x (which is -2), obtaining -1, squaring the result, and then adding this 1 to and subtracting this 1 from x^2-2x)  →  x^2-2x+ 1  - 1  +26=0

Rewriting x^2-2x+ 1 as the square of a binomial, we get:

 (x - 1)²  - 1  +26=0, or  (x - 1)²  - 1  +26=0, or   (x - 1)² = -25

Answer: There are 48 students in the class.

Step-by-step explanation:

Let the number of students = S

Let the number of benches = B

If 4 students sit on each bench, 3 benches are left vacant.

S = 4(B - 3)

S = 4·B - 12 } Equation 1

If 3 students sit on each bench, 3 students still standing.

S = 3·B + 3 } Equation 2

We can match the two equations because they both indicate the same number of students.

4B - 12 = 3·B + 3

on solving this

4·B - 3·B = 3 + 12

B = 15 → number of benches

That is the number of benches, therefore substituting the value for B in equation 1

S = 4·B - 12 Equation 1

S = 4·15 -12

S = 60 - 12 = 48 → number of students

Answer: There are 48 students in the class.

There are 48 students and 15 benches.

If 4 students sit on each bench, 3 benches are left vacant.

48students ÷ 4students/bench = 12 benches are occupied and left 3 vacant benches.

If 3 students sit on each bench, 3 students still standing.

15benches * 3 students/bench = 45 students are sitting and 3 students remain standing.

[tex]\textit{\textbf{Spymore}}[/tex]​​​​​​

Final answer:

By creating a system of equations from the given conditions, the number of students in the class is calculated to be 48.

Explanation:

To find the number of students in the class based on the provided scenario, we can set up a system of equations based on the given conditions:

If 4 students sit on each bench, 3 benches remain empty.

If 3 students sit on each bench, 3 students remain standing.

Let's use B to represent the total number of benches and S to represent the total number of students. The first condition tells us that when 4 students sit on each bench, there are B - 3 benches filled, which means 4(B - 3) students are seated. The second condition implies that if 3 students sit on each bench, all the benches are filled, and 3 more students are still standing, which can be represented by 3B + 3.

Therefore, we can write two equations as follows:

4(B - 3) = S

3B + 3 = S

Since both expressions equal S, we can set them equal to each other:

4(B - 3) = 3B + 3

Simplifying this equation, we can find the number of benches (B), and then substitute back to find the number of students (S).

4B - 12 = 3B + 3

B = 3 + 12 = 15 benches

Now we substitute B into one of our original equations to find S:

S = 4(B - 3)

S = 4(15 - 3)

S = 4 × 12

S = 48 students

Therefore, there are 48 students in the class.

Step-by-step explanation:

Add them together to get rid of the y.

-6x = -4 - y

-7x = -22 + y

=

-13x = -26

Then solve for x.

-13x/-13 = -26/-13

x = 2

Now plug in the x value into either equation and solve for y.

-7(2) = -22 + y

-14 = -22 + y

-14 + 22 = -22 + 22 + y

8 = y

So...

x = 2

y = 8

(2,8)

Answer:

The solution is (-2, -16).

Step-by-step explanation:

-6x = -4-y  can be solved for y:  y = 6x - 4

-7x = -22 + y

In the second equation, substitute 6x - 4 for y:

-7x = -22 + 6x - 4

Grouping like terms:  0 = -22 + 6x + 7x - 4, or

                                   -26  = 13x

So x = -2.  If x = -2, we can obtain the value of y from y = 6x - 4 (see above).

y = 6(-2) - 4 = -16

The solution is (-2, -16).

Answer:

There are a lot of combinations possible

Step-by-step explanation:

One of them would be that each roll of quarters is $10 and each roll of pennies is 50cents so she could have 12 rolls of quarters and 2 rolls of pennies

One of the possible combinations that Greta can have is 12 rolls of quarters and 2 rolls of pennies.

No. of quarters required to make $1 = 4 quarters

No. of coins in 1 roll of quarter = 40 coins = $10

If one roll of quarter is $10, then we can have 12 rolls which will give us $120.

Now we reached $120, we need $1 more to reach $121

No. of pennies to make $1 = 100 pennies

No. of coins in 1 roll of pennies = 50

So we need 2 rolls of pennies to make $1.

Hence, we need 12 rolls of quarters and 2 rolls of pennies to make $121.
