Step-by-step explanation:
Spencer borrowed $50 from his cousin, who charged him 6% simple interest each year. If Spencer pays his cousin back 3 years later, how much will he owe his cousin?
A
$56
B
$59
С
$68
D
$6
Given:
Principal = $50
Rate of simple interest = 6%
Time = 3 years
To find:
The amount after 3 years.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest in percentage and t is the number of years.
Putting [tex]P=50,\ r=6,\ t=3[/tex] in the above formula, we get
[tex]I=\dfrac{50\times 6\times 3}{100}[/tex]
[tex]I=\dfrac{900}{100}[/tex]
[tex]I=9[/tex]
Formula for amount is:
[tex]A=P+I[/tex]
Where, P is principal and I is the simple interest.
Putting [tex]P=50,\ I=9[/tex], we get
[tex]A=50+9[/tex]
[tex]A=59[/tex]
Therefore, the correct option is B.
Find the period of an electromagnetic wave of wavelength 2.20 × 10–2 m. A. 1.36 × 1010 s c. 7.33 × 10–11 s b. 4.54 × 101 s d. 6.60 × 106 s
Answer:
7.33 * 10^-11 s
Step-by-step explanation:
Period, T = 1 / f
c = fλ
λ = 2.20 × 10^–2 m
c = speed of light = 3 * 10^8 m
f = c / λ
f = 3 * 10^8 ÷ 2.20 × 10^–2 m
f = (3/2.2) * 10^(8-(-2))
f = 1.364 * 10^10
T = 1/f
T = 1 / 1.364 * 10^10
T = 7.33 * 10^-11 s
Which fraction is equivalent to -3/2?
A. -(3/-2)
B. 3/-2
C. -3/-2
D. -(-3/2)
no links please! :]
Answer:
It would be Choice B, since it divides to -1.5.
This is the same as when -3/2 is simplified.
Choice A would be wrong, since it would give you 1.5, due to a double negative = a postive, same with Choices C and D.
Answer:
3/-2 is the only correct solution!

Step-by-step explanation:
A 13-foot ladder is leaning against a building, forming a right triangle. The height where the ladder touches the building is 7 feet more than the distance of the base of the ladder from the building. At what height does the ladder hit the building
Answer:
Step-by-step explanation:
The length of the ladder is the length of the hypotenuse of the right triangle formed. Since the height up the building is based on the distance the ladder is from the base of the building, and that distance is x, then the height up the building is x + 7. So what we have is a right triangle with one leg measuring x, the other leg measuring x + 7, and the hypotenuse measuring 13. Set up using Pythagorean's Theorem:
[tex]13^2=(x+7)^2+x^2[/tex] and do some simplifying. The left side is easy since 13-squared is 169; the right side not so much. We first have to expand that set of parenthesis by multiplying x + 7 by itself twice to get a second degree polynomial:
[tex](x+7)(x+7)=x^2+14x+49[/tex] and now we have:
[tex]169=x^2+14x+49+x^2[/tex] which simplifies down a bit to
[tex]169=2x^2+14x+49[/tex]
The only way to solve this for x, the height up the side of the building, is to factor. In order to do that, everything has to be on one side of the equals sign, setting the whole messy thing equal to 0:
[tex]2x^2+14x+49-169=0[/tex] and
[tex]2x^2+14x-120=0[/tex]. Begin by factoring out a 2:
[tex]2(x^2+7x-60)=0[/tex] and then factor the remaining quadratic using whatever method you are currently using in class to solve for x. Doing this will give that
x = -12 and 5. Since a side length will never be negative, we determine that x = 5 which is the distance between the bases of the buildings, and the height up the building where the ladder hits it is 12.

Jay pays $2.45 for 4 magazines. He later pays $3.75 for 6 magazines. Is the price proportional to the number of magazines? Explain
Answer:
No, It is not.
Step-by-step explanation:
Step 1: Divide the 2.45 by 4 (We are doing this to find the difference between them so we can find out what to do next.)
[tex]2.45 \div 4\\\\= 0.6125[/tex]
Step 2: Multiply 0.6125 to 6 (Now, that we've found what 1 magazine cost according to the first data, we are multiplying it by 6 because if you multiply that to 4 the answer will be 2.45. So, if we multiply 6, it will show us if they are both proportional, the same.)
[tex]0.6125 \times 6\\\\= 3.675[/tex]
Therefore, these two prices are not proportional.

Answer:
1) 69 2) 69 3) 60 4) 60 5) 51
Step-by-step explanation:
Triangles have 180 degrees interior and 360 degrees exterior. Knowing this you add all the values within a triangle and subtract it from 180 to find the missing degrees.
For the purple, the green is supplementary which means the other angle will help it equal 180 degrees. the missing green angle is 38. 38+82=120 and 180-120=60. because of vertical angles, angle 2 is 69 and angle 4 is 60. this makes 129 so 180-129=51.
Hope this helps you in some way. if not, sorry i failed you.
Answers
angle 1 = 111 degreesangle 2 = 69 degreesangle 3 = 60 degreesangle 4 = 60 degreesangle 5 = 51 degreesBe sure to use the actual degree symbol instead of typing in "degrees" after each number.
========================================================
Explanation:
To find angle 1, we can use the remote interior angle theorem. The yellow angles you've highlighted (46 and 65) add up to the measure of angle 1, which is an exterior angle. So angle 1 is 46+65 = 111 degrees
The slightly longer method is to make x be the missing angle of the left-most triangle. Solve x+46+65 = 180 to get x = 69 degrees. Then note how angle x and angle 1 are supplementary, meaning x+(angle1) = 180 leads to angle 1 = 111 degrees (because 180-69 = 111)
------------------------
Angle 2 is 69 degrees since angle x = 69, which is a vertical angle to angle 2. Or you could note that angle 1 and angle 2 are supplementary
(angle1)+(angle2) = 180
(111)+(angle2) = 180
angle2 = 180-111
angle 2 = 69 degrees
This method is used to prove the vertical angles theorem is always true.
-------------------------
Angle 3 can be found using the remote interior angle theorem, but we'll be going in reverse this time. Let y be the measure of angle 3
y+82 = 142
y = 142-82
y = 60
angle 3 = 60 degrees
Like with angle 1, there's also a slightly longer method that follows the same idea as before. If you follow this method, you'll need to find the missing piece of the green angle you highlighted (which his 180-142 = 38 degrees), then use the idea that A+B+C = 180 where A,B,C are the three interior angles of any triangle.
---------------------------
Angle 3 and angle 4 are vertical angles, so they are always congruent and angle 4 is also 60 degrees
---------------------------
Let z = measure of angle 5
Focusing on the smaller triangle in the middle, we can say,
(angle2)+(angle4)+(angle5) = 180
(69) + (60) + (z) = 180
z+129 = 180
z = 180-129
z = 51
angle 5 = 51 degrees

Option BHope This Helps You ❤️f(x) = -8 (5-x), what is the value of f(-4)?
Answer:
f(-4) is basically just saying that you need to use the function given while x = -4.
The function given:
f(x) = -8(5-x)
We see that f(-4) means that x has to be -4, so we can substitute it in:
f(-4) = -8(5-(-4))
f(-4) = -8(9)
f(-4) = -72
Therefore, f(-4) is -72.

Help please !!!Tomas has 135 more songs downloaded than Carl. Together they have 623 songs downloaded.
Part A
What system of equations could be used to determine how many songs each has downloaded?
Answer:
t + c = 623
t = c + 135
thomas has 379 songs downloaded, and carl has 244
Step-by-step explanation:
togheter they have 623 songs, aka the sum of thomas (t) and carl (c) is 623.
t + c = 623
thomas has 135 more than Carl. so Carl plus 135 is equal to thomas
t = c + 135
now you can solve it:
t + c = 623
(c+135) + c = 623
c + c = 488
2c = 488
c = 244
carl has 244 songs downloaded
t + 244 = 623
t = 379
thomas has 379 songs downloaded
The system of equations represents t + c = 623 and t = c + 135 and Tomas has 379 while Carl has 244 downloaded.
What is the equation?An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
As per the given,
Together they have 623 songs downloaded.
t + c = 623
Tomas has 135 more songs downloaded than Carl.
t = c + 135
By substitution,
c + 135 + c = 623
2c = 488
c =244
And , t = 244 + 135 = 379
Hence "The equations in the system show that Tomas has 379 while Carl has 244 downloaded and that t + c = 623 and t = c + 135 are represented".
