Answer:
Step-by-step explanation:
1)Since he can lose 5 pounds per week, this is a linear rate. The weight is decreasing in arithmetic progression. The formula for determining the nth term of an arithmetic progression is expressed as
Tn = a + (n - 1)d
n = number of terms(weeks)
d = common difference(5 pounds)
a= first term(300 pounds)
The equation that could be used to find how many weeks, w, it would take for him to weigh 150 pounds would be
150 = 300 + (w - 1)5
150 - 300 = 5w - 5
- 150 + 5 = 5w
w = 145/5 = 29 weeks
2) t represents the number of hours used to fix the car. The cost of t hours is 52t. Total amount paid is 210 + 52t. The equation that could be used to find, t, the length of time it took to fix the car is
210 + 52t = 527.23
3) 52t = 527.23 - 210 = 317.23
t = 317.23/52
t = 6 hours
3) Let x represent the time it will take before you and your sister have the same amount of money. The amount that you would have in x weeks is 60 + 7x
The amount that you sister will have in x weeks is 120 + 5x. The equation would be
60 + 7x = 120 + 5x
7x - 5x = 120 - 60
2x = 60
x = 60/2 = 30 weeks
4) let L represent the length of the parking lot.
let W represent the width of the parking lot.
If the length of a rectangular parking lot is 3 times its width, it means that
L = 3W
Its perimeter is 840 yards. It means that
2(L + W) = 840
L + W = 840/2 = 420
Substituting, it becomes
3W + W = 420
4W = 420
W = 420/4 = 105
L = 3 × 105 = 315
Length = 315 yards
Which of the following side lengths are the legs? 6, 14, and 12
Answer:
The side lengths that are the legs are 6 and 12 because the hypotenuse is the largest side length of a triangle (since there are three side lengths shown).
Answer:
6 & 12
Step-by-step explanation:
In a right triangle, the greatest side length belongs to hypotenuse, other 2 numbers represent the legs
so as per the given, 14 is hypotenuse ans 6 & 12 are legs

Sue wants to increase 160 by 4%
She writes down
160 x 1.4 = 224
Sue's method is wrong.
a) Instead of multiplying by 1.4, write down
what she should have multiplied by
Bill wants to decrease 160 by 6%
b) Complete the statement below to show how Bill can decrease 160 by 6%
160 × ___ =___
Answer:
see explanation
Step-by-step explanation:
An increase of 4% = 104% = [tex]\frac{104}{100}[/tex] = 1.04
Sue should have multiplied by 1.04
(b)
A decrease of 6% = 94% = [tex]\frac{94}{100}[/tex] = 0.94 , thus
160 × 0.94 = 150.4
Step-by-step explanation:
NOTE: Increasing x by p% means multiplying x by (1+p%).
4% = 4/100 = 0.04then
increase 160 by 4% means multiply 160 by (1+4%)
in other words:
1+0.04 = 1.04
increase 160 by 4% means 160 by 1.04
160×1.04 = 166.4
160×(1 - 6%) = 160×(1 - 0.06) = 160×0.94 = 150.4brainliest will be given, plz help me
Answer:
200,000 x 0.05 = 10,000
200,000 + 10,000 = 210,000
This will be 2015 (210,000)
210,000 x 0.05 = 10,500
210,000 + 10,500 = 220,500
2016
220,500 x 0.05 = 11250
220,500 + 11,250 = 231,750
231,750 should be the value

Step-by-step explanation:
If x^2 is added to x, the sum is 56. Which of the following could be the value of x?
Answer:
-8, 7
Step-by-step explanation:
Set up an equation.
x² + x = 56
Set the equation equal to zero and factor.
x² + x - 56 = 0
(x + 8)(x - 7) = 0
Solve for x.
x + 8 = 0
x = -8
x - 7 = 0
x = 7
The possible x values are -8 and 7.

The speed of light is 3 x 108 m/s. If its frequency is 4.11 x 104 Hz, what is its wavelength?
The wavelength of the light wave is approximately 729.94 meters.
What is the speed of light?The speed of light is regarded as a fundamental natural constant. Its relevance extends well beyond its role in characterizing an electromagnetic wave characteristic.
The speed of light is a constant, and it is equal to the product of the frequency of a light wave and its wavelength.
The speed of light is 3 x 108 m/s. If its frequency is 4.11 x 104 Hz
So if the frequency of a light wave is given, we can use this formula to calculate its wavelength:
wavelength = speed of light / frequency
Plugging in the values given in the question, we get:
wavelength = 3 x 10⁸ m/s / 4.11 x 10⁴ Hz
wavelength = 3 x 10⁸/ 4.11 x 10⁴
wavelength = 3 / 4.11 x 10⁸/10⁴
Performing the calculation, we find that the wavelength of the light wave is approximately 729.94 meters.

Are the expressions –0.5(3x + 5) and –1.5x + 2.5 equivalent? Explain why or why not.
Answer:
No.
Step-by-step explanation:
If you distribute the 1st equation out, you will be able to see that it is -1.5x - 2.5 while the other equation is -1.5x + 2.5. Since you have to distribute the negative, they are not equivalent.
Answer:
Both expressions are not equal.
Step-by-step explanation:
-0.5(3x+5) = -1.5x - 2.5
–1.5x+2.5 = -1.5x + 2.5
The first expression results in subtracting 2.5, the second expression results in adding 2.5.
Find the sum of the sequence: 108, 105, 102,...,15
Answer:
1968
Step-by-step explanation:
The given sequence is a finite arithmetic sequence.
Step 1: Determine the number of terms in the sequence
For an arithmetic sequence, the nth term:
A(n)=a+(n-1)d
In the sequence:
First term, a=108Last term, l=15Common difference, d=105-108= -3Therefore, to find which term the number 15 is, we have:
15=108+(n-1)(-3)
15=108-3n+3
15=111-3n
3n=111-15
3n=96
Number of terms in the sequence, n=32
Step 2: Find the sum of the sequence
For an arithmetic sequence with a given first and last term:
[tex]Sum, S(n)=\frac{n}{2}(a+l)\\ =\frac{32}{2}(108+15)\\=16*123\\$Sum of the sequence, S(n)=1968[/tex]

Eruptions of the Old Faithful geyser have duration times with a mean of 245.0 sec and a standard deviation of 36.4 sec (based on sample data). One eruption had a duration time of 110 sec.
Answer:
Difference between time = -135 sec
Step-by-step explanation:
Given:
Mean eruption = 245 sec
Standard deviation = 36.4 sec
One eruption had a duration time of 110 sec
Find:
Difference between duration time of 110 sec and mean = ?
Computation:
⇒ Difference between time = One eruption duration time - Mean
⇒ Difference between time = 110 sec - 245 sec
⇒ Difference between time = -135 sec

Answer ASAP 84.9 66.2 38.2 33.8
Step-by-step explanation:
You need to use trigonometric stuff here. Since you're given the hypotenuse and an angle you can plug that right into an equation.
Recall that sin is opposite over hypotenuse and cos is adjacent over hypotenuse.
[tex]sin(\theta)=\frac{o}{h} \\sin(30)=\frac{x}{14} \\0.5=\frac{x}{14} \\x=7[/tex]
Now that you know the opposite side (DC) you can use tan, too, but I'm going to use cos.
[tex]cos(\theta)=\frac{a}{14} \\cos(30)=\frac{x}{14} \\\frac{\sqrt{3} }{2} =\frac{x}{14} \\x=7\sqrt{3}[/tex]
This is the adjacent side (BC). I put it in its exact value, but in decimal form it's ≈12.124.
Now you can do the perimeter:

If k(x) = 5x-6, which expression is equivalent to (k+k) (4)?
Answer:
5(4) - 6 + 5(4) - 6
Step-by-step explanation:
k(x) = 5x - 6
(k+k)(x) = 5x - 6 + 5x - 6
(k+k)(4) = 5(4) - 6 + 5(4) - 6
=> Option D is correct
Hope this helps!
The expression is equivalent to (k+k) (4) will be 5(4) - 6 + 5(4) - 6. The correct option is B.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The expression will be solved as below:-
k(x) = 5x - 6
(k+k)(x) = 5x - 6 + 5x - 6
(k+k)(4) = 5(4) - 6 + 5(4) - 6
Therefore, the expression is equivalent to (k+k) (4) will be 5(4) - 6 + 5(4) - 6. The correct option is B.
