Answer:
Step-by-step explanation:
The direct distance there (without the island in the way) is found using the Pythagorean Theorem
c^2 = a^2 + b^2
a = 8.4
b = 11.5
c = ?
c^2 = 8.4^2 + 11.5^2 Square the length of the legs.
c^2 = 70.56 + 132.25 Combine
c^2 = 202.81 Take the square root.
c = 14.24
But the island is there. The distance travelled = 8.4 + 11.5 = 19.9 miles
So the additional distance = 19.9 - 14.24 = 5.66 miles.

The relation shown in graph (A) is a b because the ordered double satisfies the condition of the function option (A) Is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The ordered double (x, y) is shown in the graphs.
As we know, from the definition of the function, they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
From the graph, the ordered double satisfies the condition of the function.
Thus, the relation shown in graph (A) is a b because the ordered double satisfies the condition of the function option (A) Is correct.

Allison measured a line to be 5.4 inches long. If the actual length of the line is 5.5 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answer:
1.85%
Step-by-step explanation:
→ Find the difference between the actual and predicted
5.5 - 5.4 = 0.1
→ Divide answer by 5.4
0.1 ÷ 5.4 = 0.01851851851
→ Multiply answer by 100
0.01851851851 × 100 = 1.85%

the sum of 16 numbers is 240.The average of 6 of those numbers is 10. the average of the remaining numbers is
Answer:
18
Step-by-step explanation:
If the average of 6 numbers is 10, then the sum of those 6 numbers is:
6 x 10 = 60
To calculate the sum of the remaining 10 numbers, subtract 60 from the total sum of all the numbers:
240 - 60 = 180
Therefore, the average of the 10 remaining numbers:
180 ÷ 10 = 18

will stopped by the grocery store for his wife he bought a pizza for 5.99 and 3 avacodos his total was 8.54 write an equation to find the cost if each avacodo
Answer:
each avocado is 0.85 cents
Step-by-step explanation:
you will subtract $8.54 and $5.99 and you will get $2.55 then, when you get that and you will divide $2.55 by 3 and the total will come out to 0.85 so that means that each avocado is 84 cents

Please help it’s urgent
Answer: $112
Step-by-step explanation:
o get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 560 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 560 is 100%, so we can write it down as 560=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 560=100%
2) x=20%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
560/x=100%/20%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 20% of 560
560/x=100/20
(560/x)*x=(100/20)*x - we multiply both sides of the equation by x
560=5*x - we divide both sides of the equation by (5) to get x
560/5=x
112=x
x=112
now we have:
20% of 560=112

How many significant figures are in the measurement 1. 050 L? a. 1 b. 2 c. 3 d. 4.
Answer:
C) 3
Step-by-step explanation:
The number of significant figures in a measurement basically means how many decimal digits there are after the decimal point. Since the decimal portion of the measurement is 050, there are 3 digits, so there are 3 significant figures in the measurement
Find the ratio of 30 minutes to 15 hours. method needed.
Answer:
2.1
Step-by-step explanation:
Here we will simplify the ratio 30:15 for you and show you how we did it.
To simplify the ratio 30:15, we find the greatest common divisor of 30 and 15, and then we divide 30 and 15 by the greatest common divisor.
The greatest common divisor that you can use to simplify 30:15 is 15. Which means the answer to ratio 30:15 simplified is: 2.1

A restaurant receives a shipment of 5,000 ketchup packets. In one week, they use 1,779 packets. The next week, they use 2,415 packets. How many ketchup packets does the restaurant have left?
Answer:
806 ketchup packets
Step-by-step explanation:
5000-1779=3221
3221-2415=806
The restaurant has 806 ketchip packets left
Answer:
5,806
Step-by-step explanation:
Because they got there 5,000 packets they subtracted 1,779 packets
5,000-1,779=3,221
Next remember they get 5,000 packets each week so then you add 5,000 to 3,221
3,221+5,000=8,221
next 2,415 packets were used so subtract 8,221 bu 2,415
8,221-2,415=5,806 so there's your answer

sarah hopes to be 5 feet in her next birthday. right know she is 148 cenmeter tall.how many more centimerter does sarah need to grow before her next borthday
Answer:4
Step-by-step explanation:
Well its actually 4.4 but if you round down its 4 centimeters and 5 feet equals 152.4 so that minus 148 is 4.4
Answer:
Step-by-step explanation:
1 foot is 12 inches
1 inch = 2.54 cm
12 inches = 2.54 cm * 12 = 30.48 cm
5 feet make 30.48 cm * 5 = 152.4 cm
She is currently 148 cm
She needs to grow 152.4 - 148 = 4.4 cm

x-2y=8
8x+6y=42
Answer:
(6,-1)
Step-by-step explanation:
Hi there!
We are given the following system:
x-2y=8
8x+6y=42
And we want to solve it by substitution
Substitution is where we solve one of the equations in the system for a variable for an expression containing the other variable, then substitute that expression into the other equation, then solve the equation for that variable, then use the value of the solved variable to find the value of the first variable.
It's easier to solve a system for a variable if the leading coefficient in front of a variable is 1, like with x in x-2y=8
So let's solve the equation for x.
add 2y to both sides
x-2y=8
+2y +2y
________________
x=2y+8
Now substitute 2y+8 as x in 8x+6y=42
8(2y+8)+6y=42
Multiply
16y+64+6y=42
Subtract 64 from both sides
16y+6y=-22
Add 16y and 6y together
22y=-22
Divide both sides by 22
y=-1
Substitute -1 as y into x=2y+8 to solve for x
x=2(-1)+8
Multiply
x=-2+8
x=6
The answer is x=6, y=-1, or as a point, (6, -1)
Hope this helps!

The members of the city cultural center have decided to put on a play once a night for a
week. Their auditorium holds 600 people. By selling tickets, the members would like to raise $3,300
every night to cover all expenses. Let d represent the number of adult tickets sold at $7.50. Lets
represent the number of student tickets sold at $4.50 each. If all 600 seats are filled for a
performance, how many of each type of ticket must have been sold for the members to raise exactly
$3,300? At one performance there were two times as many student tickets sold as adult tickets. If
there were 300 tickets sold at that performance, how much below the goal of $3,300 did ticket sales

Answer:
m∠Q = 121°
m∠R = 58°
m∠S = 123°
m∠T = 58°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Create an expression for the sum of all the angles and equate it to 360, then solve for x:
∠Q + ∠T + ∠S + ∠R = 360
⇒ 2x + 5 + x + 2x + 7 + x = 360
⇒ 6x + 12 = 360
⇒ 6x = 360 - 12 = 348
⇒ x = 348 ÷ 6 = 58
So now we know that x = 58, we can calculate all the angles:
m∠Q = 2x + 5 = (2 x 58) + 5 = 121°
m∠R = x = 58°
m∠S = 2x + 7 = (2 x 58) + 7 = 123°
m∠T = x = 58°
Paulo has R$45.00 and Carlos has 5/9 of that amount. How many Carlos has? How many do the two have together?
We are given –
Paulo has R$45.00 and Carlos has 5/9 of that amount.We are asked to find, how much Carlos owns and how much they have together.
Explanation :-
At first, we just need to multiply 45 by 5, and then we will divide the value by 9, so we find that:
[tex]\qquad[/tex][tex] \bf \longrightarrow 45 \times 5 = 225[/tex]
[tex]\qquad[/tex][tex] \bf \longrightarrow \dfrac{225}{9} = 25[/tex]
Therefore, we find that Carlos has 25 R$.Now to find out how much they have together. We have to add Paul's amount to Carlos' amount for that.
[tex]\qquad[/tex][tex] \bf \longrightarrow 25 + 45 = 70[/tex]
Henceforth, they both have 70 R$. together.-3x+5=-2(x+7)+2x+4 infinite soultion

Kiara had the following car expenses last year: $3060 in car payments; $94 for license
and registration: $128 in tax; $1080 for insurance; $290 for parking; $398 for wear and
tear, $1520 for maintenance; and $930 for gas. If she drove 12,500 miles last year, what
was her average cost per mile?
Average cost per mile is $0.6
How to calculate the average cost per mile?To calculate the average cost per mile that Kiara had to pay, we perform the following operations:
We add up all the payments Kiara made related to her car.
$3,060 + $94 + $128 + $1,080 + $290 + $398 + $1,520 + $930 = $7,500Later we divide the total value, in the number of miles traveled by Kiara
