Answer:
34.1 minutes
Step-by-step explanation:
distance= 2miles,time=11 minutes
pace=velocity
velocity= distance/time
V= (2/11) miles/minutes
since the pace is maintained. then,
time taken to run 6.2 miles would be
time=distance/velocity
T= 6.2miles/(2/11)miles/minutes
T= [(6.2×11)/2]minutes
T= 34.1 minutes.
how far would a 4.0 cm tall object be located from a reflecting surface with a focal lenght that is equal to 5 cm if it is to create an image seen 15 cm behind the mirror. Determine the image size
Answer:
HERE IS YOUR ANSWER
Step-by-step explanation:
Use the mirror equation:
1/di + 1/do = 1/f
where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)
Substitute and solve for do.
1/do + 1/(-10 cm) = 1/(15 cm)
1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)
do = 6 cm

Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 of his collection and takes 27 cards to school to give his friends. How many baseball cards remain in Ryan's collection? 127 cards 90 cards 117 cards 126
Answer:
117 cards
Step-by-step explanation:
Total number of cards in the collection of Ryan = 216
Number of cards given to his brother = ⅓ of 216 = ⅓ × 216 = 216/3 = 72
Number of cards given to his friend at school = 27
Number of baseball cards that Ryan has remaining = 216 - (72 + 27)
= 216 - 99
Number of cards remaining = 117 cards

Write the equation of the line graphed below in Point-Slope form. Use the point labeled on the graph. State the slope and point.
Answer:
The Point-Slope form is y - 1 = 4 ( x + 1 )
Step-by-step explanation:
First you have to find the slope which is 4. To get that you get 2 points and do rise/run. I chose the 2 points (-2,-3) and (-1,1).
Since the formula for point-slope form is:
y - y1 = m ( x - x1 )
You simply fill in the blanks with the given point which is ( -1 , 1 ).
Therefore, the point-slope form is:
y - 1 = 4 ( x + 1)

Janelle graphed a line through (−6, 5) that had a slope of −79. What is the y-coordinate of a point on the line that has an x-coordinate of 3?
Answer:
The value of the y-coordinate is -706
Step-by-step explanation:
The equation of a straight line is;
y = mx + c
where m is slope and c is t-intercept
Given the slope, we can write the equation as;
y = -79x + c
we need to get c
Just put in the x and y values of the given point
X = -6 and y = 5
5 = -79(-6) + c
5 = 474 + c
c = 5-474 = -469
So the complete equation of the line would
be ;
y = -79x - 469
To get the y-coordinate of the point, just insert the x value into the equation;
y = -79(3) - 469
y = -237 - 469 = -706
Joanne has 20 books on crafts and cooking. she has 6 more cookbooks than craft books. how many of each does she have?
Answer:
Crafts books: 7
Cookbooks: 13
Step-by-step explanation:
Let x be the crafts book
Let y be the cookbooks
Solve for x:
Plug x and y in: x + y = 20Re-write: y = x + 6Plug in x + 6 instead of y: x + x + 6 = 20Combine like terms: 2x + 6 = 20Subtract 6 from each side, so it now looks like this: 2x = 14Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 7Solve for y:
Re-use an equation from above: y = x + 6Plug in the value of x: y = 7 + 67 + 6 = 13So, y = 13I hope this helps!

There are two different maps of California.
The scale on the first map is 1 cm to 20 km. The distance from Fresno to San Francisco is 15 cm.
The scale on the second map is 1 cm to 100 km.
What is the distance from Fresno to San Francisco on the second map? Explain your reasoning.
Include your answer in your response: The distance on the second map is _______ because __________.
if someone helps me on this I'm giving them a lot of points,
Answer:
the distance from Fresno to San Francisco on the second map is 75cm
Step-by-step explanation:
The scale on the first map is 1 cm to 20 km
The distance from Fresno to SanFrancisco is 15 cm
1cm/20km = 15cm
The scale on the second map is 1 cm to 100 km.
1cm/100km = x
X= 15cm*100km/20km *1cm/1cm
X=15cm *5
X= 75 cm
the distance from Fresno to San Francisco on the second map is 75cm

Write fractions for points A and B on the number line. (yup, I'm dumb)
Answer:
2/6 = A and 5/6 =B
Step-by-step explanation:
the line is split into 6 segments. so this means each little line is 1/6. if each line is 1/6, 2 lines, which is A, is 2/6 and 5 lines is 5/6. just multiply 1/6 * th number of lines from the start of the line to the letter
The fraction for point A on the number line will be 2/6 and the fraction for point B will be 5/6 respectively.
What is a fraction?Parts of an entire or group of items are represented by fractions. Each fraction has two components. The numerator refers to the number at the top of the line. It indicates how many equal portions of the total or collection are taken. The denominator refers to the figure below the line. It displays how many identical things there are in a collection or how many total equal elements there are to a whole.

PLS ANYBODY HELP ME ON THIS 20 points
Answer: No, he is incorrect
Step-by-step explanation:
No, he is incorrect. Using a number line to model thirds means that each space that is 1/3 should be divided into 3 parts, not 2 parts. 6 parts divided into 3 groups gives 2 parts out of 9 parts total, so the answer is 2/9.
What will be the length of third side of a right angled triangle whose hypotenuse is 5 cm and one of the side is 3 cm? What will be the length of third side of a right angled triangle whose hypotenuse is 5 cm and one of the side is 3 cm?
Answer:
4
Step-by-step explanation:
You would use a^2+b^2=c^2
a^2+3^2=5^2
a^2+9=25 subtract nine from both sides
a^2=16
find the square root of 16 which is 4
so the other side of the triangle is 4
Answer:
4 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the length of the 3 rd side, then
x² + 3² = 5²
x² + 9 = 25 ( subtract 9 from both sides )
x² = 16 ( take the square root of both sides )
x = [tex]\sqrt{16}[/tex] = 4
The third side is 4 cm
