Answer:1 hour and 15 minutes
Step-by-step explanation:
so it takes her 34 minutes for 4 problems so for 2 problems its 17 minutes
and then you do the 34 times 2 because its 4 problems so you add that and that = 68 minutes and then you add 17 for the 2 problems and thats 85 minutes or 1 hour and 15 minutes
Answer:
1 hour & 25 minutes (85 minutes)
Step-by-step explanation:
Time taken for 1 problem,
→ 34 ÷ 4
→ 8.5 minutes
Now time taken for 10 problems,
→ 8.5 × 10
→ 85 minutes
Hence, answer is 85 minutes.

All changes save . What is the next term of the arithmetic sequence 24, 16, 8, 0, ...? Show the explicit equation
32 is the next term in the arithmetic sequence of 24,16,8,0,...
To find out what is the next term of the arithmetic sequence
24, 16, 8, 0, ...
To show the explicit equation:
We have an arithmetic sequence because the difference between the terms is constant:
0 → 8: Δ → 8
8 → 16: Δ → 8
16 → 24: Δ → 8
From this the next term is simply:
24 + 8 = 32
And this sequence can be explicitly written as:
[tex]a_{n} = a_{1}(n-1)d[/tex]
Where:
[tex]a_{n}[/tex] = nth term
[tex]a_{1}[/tex] = first term
d = distance between the terms
n = any index number
Therefore we have:
[tex]a_{n} = 1.(n-1)8 = 8.(n-1)\\\\a_{n} = 8. (n-1)[/tex]

kg.
The mass of a male polar bear is about 700 kg, or 7 x 10² kg.
About how many times more massive is the right whale than the polar bear?
Answer:
The right whale is 100 times more massive that the polar bear
Step-by-step explanation:
7 x 10^2 = 700 kg
7 x 10^4 = 70,000kg.
70,000 / 700 = 100Check: 700 x 100 = 70,000

6 hours biking the second day. They biked at one speed the
first day and a different speed the next day. At what speed
(miles per hour) could they have biked each day? Explain.
They could have biked on first day at the speed of x/4 miles per hour and on the second day at the speed of (88-x)/6 miles per hour where x is the distance covered on first day.
According to the question,
We have the following information:
Jaden and Emilia biked 88 miles from Daytona Beach to Jacksonville in 2 days. They spent 4 hours biking the first day and 6 hours biking the second day. They biked at one speed the first day and a different speed the next day.
Now, let's take the distance covered on first day to be x miles.
Distance covered on second day = 88-x miles
Following formula is used to find the speed of an object:
Speed = distance/time
Speed of first day = x/4 miles per hour
Speed of the second day = (88-x)/6 miles per hour
Hence, they could have biked on first day at the speed of x/4 miles per hour and on the second day at the speed of (88-x)/6 miles per hour where x is the distance covered on first day.

States is the Columbus Circle in New York City, and has a circular monument in
the center covering approximately 148,000 square feet. What is the radius of the
monument, to the nearest hundredth?
From the given data of traffic circle, the center of the circular monument is covering approximately 148,000 square feet then the radius of the monument is equal to 217.10 feet.
As given in the question,
Given that traffic circle is a round intersection.
It has circular monument in the center.
Area covered by circular monument is equal to 148,000 square feet.
Let us consider radius of the circular monument be 'r'
Area of circular monument = 148,000
⇒ πr² = 148,000
⇒r² = 148,000 / π
⇒ r² = 148,000/ 3.14
⇒ r = √148,000/ 3.14
⇒ r = 217. 103... feet
⇒ r = 217.10 feet ( nearest hundredth)
Therefore, from the given data of traffic circle, the center of the circular monument is covering approximately 148,000 square feet then the radius of the monument is equal to 217.10 feet.

By using slope intercept form of equation of line, it can be inferred that Point C is on the line y = x - 5
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan\theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
Here, the given slope intercept form is y = x - 5
For Point A
Putting x = -3
y = -3 -5 = -8 which is not equal to 2
Point A is not on the line y = x - 5
For Point B
Putting x = 1
y = 1 -5 = -4 which is not equal to 6
Point B is not on the line y = x - 5
For Point C
Putting x = 3
y = 3 -5 = -2
Point C is on the line y = x - 5
For Point D
Putting x = -2
y = -2 -5 = -7 which is not equal to -3
Point D is not on the line y = x - 5

The value of x in the polygon is 9
What is a Heptagon?A heptagon is a polygon that has seven sides. It is a closed figure having 7 vertices. A heptagon is also sometimes called Septagon.
In Geometry, the shape that is bounded by at least three straight lines or at least three interior angles is called polygon. The most common examples of polygons are
Triangle ( 3 sided polygon)
Quadrilateral ( 4 sided polygon)
Pentagon ( 5 sided polygon)
The polygon is a heptagon with number of sides n = 7
sum of interior angles of a polygon = (n - 2) x 180
if n = 7,
Sum of the interior angles = (7 -2) x 180
= 5 x 180
= 900
summing all the angles in the given polygon, we have
135 + 3x + 31 + 4x + 15 + 6x - 8 = 120 + 7x - 64 + 5x - 4 = 25x + 675
25x + 675 = 900
25x = 900 - 675
25x = 225
x = 225/25
x = 9

Claire’s mom is 4 years older than twice Claire’s age. The sum of their ages is 58 years. Claire’s age is ___ years, and her mothers age is ____ years
Claire is 18 years old and her mother is 40 years old.
Answer with explanation:
Let Claire's age = x years
Age of Claire's mother =(2 x +4 ) years
Sum of the ages of Claire and her mother =58 years
If we write the above statement in terms of equation , it will be
⇒ x + 2 x +4=58
⇒3 x +4=58
⇒3 x =58 -4
⇒3 x =54
Dividing both side by , 3 , we get
→x=18
Claire's age = 18 years
Age of Claire's mother =(2 x +4 )=2×18+4=36+4= 40 years
The sum of their ages is 58. The "sum of their ages" includes:
Claire's age + 2(Claire's Gage) + 4 = 58
3(Claire's age) + 4 = 58
3 x Claire's age = 58 -4 = 54
Claire's age= 54/3 = 18
Claire is 18 years old.
Since Claire's mom is 4 years older than twice clears age, her age is (18 x 2) + 4 = 40
So Claire is 18 and her mother is 40

a driver charges $3 per mile for the first 2 miles, then $2 for each additional mile. if you traveled 8 miles, what would the total fee be? and if you traveled 50 miles, what would the total fee be?
PLEASE HURRY AND ANSWER!!!!! THIS PAPER IS DUE TOMORROW MORNING! AND ITS FOR A GRADE!!!!
Hey there! I would be glad to help you out.
For the first two miles, the price would be six dollars total.
For every mile after that, you would be charged two dollars.
Assuming that you travel 8 miles, you would have to pay six dollars for the first two miles (3*2), and twelve dollars for the last six miles, totaling eighteen dollars.
So the price of an eight mile ride would be eighteen dollars.
You can use this logic for the 50 miles trip too. After traveling 2 miles ($6), there will be 48 more miles.
For these 48 miles, it'll only charge you two dollars each, which would total 96 dollars.
So the price of a fifty mile ride would total $102.

measurement was 5% and his own measurement was smaller than the length, what is the length of the room?
A. 3.78m B. 3.80m C. 4.18m D. 4.20m
Answer:
D)
Step-by-step explanation:
Percentage word problems:Let the original length be 'x'.
Percentage error = 5 %
So, (100 -5)% = 95% of the original measurement is 3.99 m
95% of x = 3.99
[tex]\sf \dfrac{95}{100}*x = 3.99[/tex]
[tex]\sf x = \dfrac{3.99*100}{95}\\\\x = \dfrac{399}{95}\\\\\\x = 4.2 m[/tex]
Original length = 4.2 m
Find the equation of the quadratic with a vertex of ( -1, -5) and the point (2,13)
The quadratic equation with a vertex at (-1, -5) that passes through (2, 13) is:
y = 2*(x + 1)^2 - 5
How to find the quadratic equation?A quadratic equation with a leading coefficient a and a vertex (h, k) is written as:
y = a*(x - h)^2 + k
Here we know that the vertex is (-1, -5), then our parabola is something like:
y = a*(x + 1)^2 - 5
Now we also know that the quadratic equation contains the point (2, 13), then we can replace the values to get:
13 = a*(2 + 1)^2 - 5
13 = a*3^2 - 5
13 = a*9 - 5
13 + 5 = a*9
18/9 = a
2 = a
Then the quadratic equation is:
y = 2*(x + 1)^2 - 5
