Answer:
18/7
Step-by-step explanation:
x=reciprocal of 7/18
7/18 * x = 1 ==> the product of the reciprocal of a number and the number itself is one since the product of the numerator and the product of the denominator would be the same.
7x/18=1
7x/18 * 18=1*18
7x=18
7x/7=18/7
x=18/7
the sum of two numbers 94. their diffirence is 12
Lets denote the numbers x and y:
The sum of two numbers 94 → x + y = 94
Their difference is 12 → x - y = 12
We have:
x + y = 94
x - y = 12
---------------- Add both equations
2x = 106
x = 106/2
x = 53
Using first equation:
x + y = 94
53 + y = 94
y = 94 - 53
y = 41
A/ The numbers are 53 and 41.
Colin invests £4600 into his bank account.
He receives 4% per year compound interest.
How much will Colin have after 7 years?
Give your answer to the nearest penny where appropriate.
Answer:
6,053.29
Step-by-step explanation:
Use this formula:
A= p(1+r/n)^nt
A= Amount (?)
P= Principal (4600)
r - interest rate (4%)
n= number of times the interest is compounded per year (1)
t= time (7 years)
Answer:
£6053.29 to the nearest penny.
Step-by-step explanation:
Amount after 7 years = 4600(1 + 0.04)^7
= 4600 * 1.04^7
= £6053.286.

|5k-8| / 10 = 2
|5k-8| / 10 is a fraction btw
Answer:
K is -12/5
k is also 28/5
Step-by-step explanation:
Here, we want to solve the equation
|5k-8| = 10(2)
5k-8 = 20
5k = 20 + 8
5k = 28
k = 28/5
or
5k-8 = -20
5k = -20 + 8
5k = -12
k = -12/5
in a right triangle, the side c opposite the right angle is called the hypotenuse, and the other two sides a and b are called legs. the pythagorean theorem states that in any right triangle, the lengths of the three sides are related by the equation . use the pythagorean theorem to answer the following question. determine the length of the hypotenuse in a right triangle with legs 5 inches and 12 inches. a. approximately 13.38 inches b. 13 inches c. 169 inches d. 17 inches
The length of the hypotenuse is 13.
A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
According to the question ,
Given that , legs is 5 inches and 12 inches
how to find hypotenuse :
we know , c^{2} = a^{2} + b^{2}
⇒ c^{2}= 5^{2} + 12^{2}
⇒ c^{2} = 25 + 144
⇒ c = \sqrt{169}
⇒ c = 13
The length of the hypotenuse is 13.
Correct option is (b) 13 inches .

Complete the statement to describe the expression (a+b+c)(d+e+f)
The expression consists of _ factors, and each factor contains _ terms.
Fill in the blanks.
Answer:
Please check the explanation.
Step-by-step explanation:
We know that if we multiply 3 and 4, we get 12.
In other words, 3 × 4 = 12
Thus, 3 and 4 are factors of 12.
now
Given the expression
[tex](a+b+c)(d+e+f)[/tex]
The given expression consists of two factors which are:
(a+b+c)(d+e+f)We also know that an expression can consist of terms, a term may be a constant or a variable. It can be both as well.
For example, in the expression, 4b + 2, 4b and 2 are terms.
so,
The factor (a+b+c) consists of 3 terms. These terms are a, b and c.Similarly, the factor (d+e+f) consists of 3 terms. These terms are d, e, and f.Find the selling price of a karaoke machine with a 60.5% markup.
Answer:
$99.91
Step-by-step explanation:
If the markup is 60.5%, then the selling price would be 160.5% of the original price.
160.5%=1.605
$62.25*1.605=$99.91125
Since you can't have 0.00125 dollars, lets round to the nearest hundredth.
The selling price is $99.91

The sum of two or more vectors is called the Resultant.
The Resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. If displacement vectors A, B, and C are added together, the result will be vector R.

A friend gives you two baseball cards for your birthday. Afterward, you begin collecting them. You buy the same number of cards once each week. The equation y = 4x + 2 describes the number of cards, y, you have after x weeks.
Discuss which points on the line do not make sense in this situation. Then plot three more points on the line that do make sense.
Answer:You have 2 cards upfront, so the constant term in this linear equation is 2. The slope represents how many more cards you buy or acquire per day, week or month (depending upon how eager you are to fatten your collection). ;)
y = 2 + (rate of acquisition of cards)(time)

hi guys can u please help and doing hw and i don't understand.
Answer:
C
Step-by-step explanation:
The weight of the weight lighting bar = the initial value/y-intercept (b) = 45
Amount of weight = x
Total amount of weight = y
The rate of change (m) = 1
Thus to write the function that models this situation, substitute m = 1, and b = 45 into y = mx + b
Thus:
y = (1)x + 45
y = x + 45

Debbie has at most $58 to spend on clothes. She wants to buy a pair of jeans for $22 and spend the rest on t-shirts. Each t-shirt cost $9. Write and solve an inequality that represents this word problem.
Answer:
The Inequality Equation =
22 + 9x ≤ 58
The number of T -shirts Debbie can buy is at most 4 T-shirts
Step-by-step explanation:
Let the number of T shirts Debbie can buy be represented as x
We are told in the question: Debbie has at most $58 to spend on clothes.
This means she would not exceed $58. She would be spending less than or equal to $58
The Inequality Equation =
$22 + $9 × x ≤ $58
22 + 9x ≤ 58
Solving the Inequality Equation above:
22 + 9x ≤ 58
9x ≤ 58 - 22
9x ≤ 36
x ≤ 36/9
x ≤ 4 shirts
The number of T -shirts Debbie can buy is at most 4 T-shirts

2(9n-1)+7(n+6)=-60
what is this answer
Answer:
n=-4
Step-by-step explanation:
2 (9n-1)+7(n+6)= -60
18n-2 +7n + 42 = -60
25n + 40 = -60
25n = -100
n = -4
Answer:
n = - 4
Step-by-step explanation:
2 ( 9n - 1 ) + 7 ( n + 6 ) = - 60
Solve the brackets.
18n - 2 + 7n + 42 = - 60
Combine like terms.
25n + 40 = - 60
Subtract 40 from both sides.
25n = - 60 - 40
25n = - 100
Subtract 25 from both sides.
n = -4

Generate the next three terms of each geometric sequence defined below. (in picture)
Answer:
a) -9, -10, -11
b)24, 36, 54
c)-10, 20, -40
Step-by-step explanation:
-8 - 1 = -9
-9 - 1 = -10
-10 - 1 = -11
a2 = 16 * 3/2 = 24
a3 = 24 * 3/2 = 36
a4 = 36 * 3/2 = 54
f(2) = 5 * -2 = -10
f(3) = -10 * -2 = 20
f(4) = 20 * -2 = -40
The next three terms of each geometric sequence are;
a) -9, -10, -11
b)24, 36, 54
c)-10, 20, -40
What is a geometric sequence?There are three parameters which differentiate between which geometric sequence we're talking about.
The first parameter is the initial value of the sequence.
The second parameter is the quantity by which we multiply previous term to get the next term.
a) The common difference is;
-8 - 1 = -9
b) The common difference is;
-9 - 1 = -10
c) The common difference is;
-10 - 1 = -11
a2 = 16 * 3/2 = 24
a3 = 24 * 3/2 = 36
a4 = 36 * 3/2 = 54
Therefore, the next terms are;
f(2) = 5 * -2 = -10
f(3) = -10 * -2 = 20
f(4) = 20 * -2 = -40

Answer:
No. Jami can mow more than her advertisement states
Step-by-step explanation:
Because she can mow 1/6 of an acre in 6 minutes, and an hour is 60 minutes long, we know that she can mow up to ten times that in one hour. Think about it this way. How many times does six minutes go into 60? 10. So Jami can mow 1/6 of an acre up to 10 times in one hour. This means that in an hour Jami can mow 10/6, or 1 and 2/3 of an acre in an hour. Thus, her advertisement is understating how quickly she can mow.
