Today, the sum of Harper's age and Cadence's age is 61. 8 years ago Cadence was 4 times older than Harper.
Part A: Enter Harper's age today.
Part B: Enter Cadence's age today.
Answer:
Harper is 17 and Cadence is 44.
Step-by-step explanation:
First, we can set up an equation to displays the sum of both ages.
Let x = Harper's age and y = Cadence's age
x+y=61
8 years ago, this means the sum will decrease by a total of 16 as we have to subtract 8 from both variables
The equation to represent 8 years ago is: x+y=45
Now we can write another equation to represent Cadence being 4 times older than Harper (8 years ago)
y=4x
We can substitute this back into the equation we had for the ages 8 years ago.
x+(4x) = 45
5x=45
x=9
Now, Harper's age 8 years ago is 9 years old. We add 8 to this number to determine that Harper is currently 17 years old.
We can insert this into the original equation to determine Cadence's age.
17+y=61
y=44
Thus, Cadence is currently 44 years old

Clovis wants to make a surprise visit to his uncle who lives out of town. he purchases an airline ticket for $69. there is a 15% sales tax on the price of the airline ticket. in addition he must pay a baggage fee of $20. when he arrives at the airport, clovis takes a taxi to his uncle's house which is 8 miles from the airport. the taxi fee is $2.50 per mile. if clovis has spent a total of $123.35 for the airline ticket and taxi, at what percent of his fare did clovis tip the taxi driver? a. 10% b. 15% c. 20% d. 25% please select the best answer from the choices provided a b c d
If Clovis has spent a total of 123.35 for airline ticket and taxi ,the percent of fare that He tip the taxi driver is At 20%.
What is percentage?A percentage serves as a number or ratio which is been expressed as a fraction of 100.
The amount paid for the airline Ticket and the Taxi is 123.35
Sales Tax on the airline Ticket is 15% of $69, which can be calculated as [tex](15/100 * 69)=10.35[/tex]
The amount without any tip can be calculated as[tex][10.35 +20+69+(2.5*8)][/tex]
To get the amount with the tip, we will substract the from the total amount of airline ticket 123.35 from amount for the tip which is
(123.35-119.35)= 4.
Then we can calculate percentage of the tip as
[tex](4/20 *100)= 20%[/tex]

#SPJ4
The answer is C
- airline ticket: $69
- sales tax, 15%: $10.35
- baggage fee: $20.
- taxi: 8 miles * $2.50 per mile = $20
Sub-total: 69 +10.35 + 20 + 20 = $ 119.35
If Clovis has spent a total of $123.35 => tip = 123.35 - 119.35 = $4.00
at what percent of his fare did Clovis tip the taxi driver?
[$4 / $20] * 100 = 20%

Say that romania puts a tariff of 6% on its exports and 21% on its imports. if romania has a trade deficit of (equivalent us dollars) $26.76 billion and gained tariff revenue of $18.9603 billion, how much are romania’s imports worth? a. $62.56 billion b. $64.29 billion c. $76.17 billion d. $97.04 billion please select the best answer from the choices provided a b c d
The amount of money that Romania’s imports are worth is equal to: C. $76.17 billion.
Given the following data:
Exports tariff = 6% = 0.06.
Imports tariff = 21% = 0.21.
Trade deficit = $26.76 billion.
Tariff revenue = $18.9603 billion.
How to calculate Romania’s imports?In order to determine how much Romania’s imports are worth, we would write a mathematical expression for the total tariff revenue and trade deficit as follows:
0.06E - 0.21I = 18.9603 .....total tariff revenue (eqn. 1).
I - E = 26.76 .....trade deficit (eqn. 2).
From eqn. 2, we have:
E = I - 26.76 ..equation 3.
Substituting eqn. 3 into eqn. 1, we have:
0.06(I - 26.76) - 0.21I = 18.9603
0.06I - 1.6056 - 0.21I = 18.9603
0.27I = 18.9603 + 1.6056
0.27I = 20.5659
I = 20.5659/0.27
I = $76.17 billion.

What is the length of HI to the nearest hundredth?
1.32 km
16.33 km
38.02 km
Answer:
16.33 km
Step-by-step explanation:
The square length of hypotenuse is equal to the sum of two legs' square value:
|HI|^2 + |JI|^2 = |HJ|^2
|HI|^2 + (24.28)^2 = (29.26)^2
|HI|^2 + 589,5184 = 856,1476 (these are full values and will be easier to calculate with a calculator, if not we can use the approximate values: 589,5 and 856,1)
subtract 589,5184 from both sides
|HI|^2 = 266,5636 find the root of boths sides
HI = 16.33 approximately
The base HI of the right triangle is approximately 16.26 km.
Given is a right triangle with perpendicular JI = 24.28 km and hypotenuse HJ = 29.26 km we need to find the base HI.
To find the base HI of the right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Let's denote the base HI as x.
According to the Pythagorean theorem:
HJ² = JI² + HI²
Substituting the given values:
(29.26 km)² = (24.28 km)² + x²
Simplifying the equation:
855.4276 km² = 590.7584 km² + x²
264.6692 km² = x²
To find x, we take the square root of both sides:
x = √(264.6692 km²)
Calculating the value:
x ≈ 16.26 km
Therefore, the base HI of the right triangle is approximately 16.26 km.

that he will fence?
The perimeter of the land that Tony will fence around the rectangular piece of land that he owns is 56 meters.
What is the perimeter of a rectangle?
The measure of the boundary of the sides of a rectangles called its perimeter. The perimeter of a rectangle is twice the sum its length and width.
[tex]P=2(l+w)[/tex]
Here, (l) is the length of the rectangle and (w) is the width of the rectangle.
The land has an area of 192 m2 and the length is 4m longer than the width. Let suppose the length is l. Thus,
[tex]l=4+w[/tex]
Now the area of rectangle is the product of length and width. Thus,
[tex]A=l\times w\\192=(4+w)\times w\\192=4w+w^2\\w^2+4w-192=0\\w^2+16w-12w-192=0\\w(w+16)-12(w+16)=0\\(w+16)(w-12)=0\\w=-16,12[/tex]
Taking positive side, w=12. The width of the rectangle is 12 m. The length of the rectangle is 4 m longer than the width. Thus, the length of it si 16 m (12+4). Its, perimeter is,

In adjoining figure a circle is inscribed in the quadrilateral ABCD given that BC is equal to 38 cm cube is equal to 27 cm and BC equal to 25 cm and that ad is perpendicular to DC find the radius of the circle.
Step-by-step explanation:
Let O be the centre of the circle. Since P and S are the points of contact of tangents AD and DC respectively, OP ⊥ AD and OS ⊥ DC
Also, AD ⊥ DC (given), therefore, OPDS is a square.
BR = BQ = 27cm...(tangents from an external point to a circle are equal in length)
therefore, CR = CB - BR = (38 - 27)cm = 11cm
SC = CR = 11 cm...(tangents from an external point) therefore, DS = DC - SC = (25 - 11) cm = 14 cm.
therefore,
Radius of a circle = OP = DS = 14 cm...(therefore, OPDS is a square).

How much do they spend in total for these cartons? Give your answer in £.
Using proportions, it is found that they spent a total of £5.6 for these cartons of apple juice.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the daily fraction of a carton they drink is given by:
[tex]\frac{1}{3} + \frac{2}{5} = \frac{5 + 6}{15} = \frac{11}{15}[/tex]
Hence, applying the proportion, over 10 days, the amount of cartons they drink is given by:
[tex]10 \times \frac{11}{15} = \frac{110}{15} = 7.33[/tex]
Rounding up, they buy 8 cartons, each at £0.7. Hence the total amount spent is given by:
