1/8 miles per hour
8 hours per mile
8 miles per hour
1/8 hours per mile
Answers
Answer:
C. 8 miles per hour
Step-by-step explanation:
1/24th of an hour is 2.5 minutes, taking Diego 2.5 minutes to ride 1/3rd of a mile
2.5 x 3 (to signify how long it would take Diego to ride a mile) = 7.5 minutes
60 divided by 7.5 = 8
Therefore, Diego's speed in MPH is 8.

Step-by-step explanation:
Answer:
1/15
Step-by-step explanation:
so theres 1/5 jam left in the far, which isn't much, and 3 friends have to split it equally between them, so the 1/5 jar of jam is split into 3,
just simply divide 1/5 by 3 and you will get 1/15 for your final answer.

is triangle abc ~ triangle def ?
Answers
Answer:
Unable to be determined.
Step-by-step explanation:
AA postulate : 2 corresponding angles that are congruent.
SSS theorem : 3 sides of a triangle that are equal to another triangle's 3 sides.
SAS postulate: 2 sides and their included angle are congruent to another triangle's 2 sides and their included angle.
This would seem to follow the SAS postulate at first, but the angle we are provided is not the included angle of the sides. In triangle ABC, we are analyzing lines AB and AC. Their included angle is A, but we are given the measure for angle B.
Same with DEF; we analyze DE and DF, who share angle A, but we are given angle E as a measure.
Therefore, we cannot determine if the triangles are similar or not.

Given:
A right angle triangle ABC, right angled at C.
To find:
The measure of θ.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
In triangle ABC,
[tex]\tan \theta=\dfrac{AC}{BC}[/tex]
[tex]\tan \theta=\dfrac{2.7}{5}[/tex]
[tex]\tan \theta=0.54[/tex]
It can be written as
[tex]\theta=\tan^{-1}0.54[/tex]
[tex]\theta\approx 28.369[/tex]
Therefore, the measure of θ is 28.369.

Which expression is equilvalent to (5g-2h)-(3h+8-4g).
Answers
Answer:
9g -5h - 8
Step-by-step explanation:
We first have to get everything out of the parentheses, so we take the negative that is surrounding the parentheses and apply it to the equation inside of it, giving us this: 5g - 2h - 3h - 8 + 4g
Then, all we need to do is simplify it into this expression: 9g -5h - 8
Answer:
9g-5h-8
Step-by-step explanation:
(5g-2h)-(3h+8-4g)

A dilation has center (0,0). Find the image of the point B ( 5/3, -7/2) for the scale factor 1/3
Answers
=======================================================
Explanation:
Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.
The coordinates of point B are x = 5/3 and y = -7/2
So we have
(1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate
and
(1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate
The point (5/3, -7/2) moves to (5/9, -7/6)

Answers
Answer:
(1/2) {ad - cb} both expressions
Step-by-step explanation:
Notice that the area of the triangle in question can be calculated as the area of the larger right angle triangle OSQ MINUS the area of the smaller right angle triangle OPR, and MINUS the area of the trapezoid RSQP.
Given the coordinates of the given points, the formulas for area of triangles and of trapezoid, we have the following area subtractions:
1/2 (a + c) (b +d) - 1/2 a* b - 1/2 c (b + b + d)=
= (1/2) { ab + ad + cb + cd - ab - 2 cb -cd } =
= (1/2) {ad - cb}
On the other hand the matrix expression is giving you 1/2 of the determinant of the given matrix such determinant is: ad - cb
Then we see that the equality is correct since (1/2) of the determinant is also :
(1/2) {ad - cb}

[tex]3\sqrt{2}[/tex]/2
Step-by-step explanation:
first we take the square root of the top and bottom:
[tex]\frac{\sqrt{72} }{\sqrt{16} }[/tex]
The denominator is 4. The numerator is harder to solve. To solve, we need to look at the factors of 72.
72= 8 * 9. This means that [tex]\sqrt{72} =\sqrt{8} *\sqrt{9} \\[/tex]
We know that the square root of 9 is 3, so now we have
[tex]\frac{3\sqrt{8} }{4}[/tex]
We're almost done!
Since 8= 2*4, and the square root of 4 is 2,
[tex]\frac{3*2*\sqrt{2}}{4}[/tex]
last, we simplify and get
[tex]\frac{3\sqrt{2}}{2}[/tex]

Pedro made a pot of coffee for some friends. he served 34 ounces to his friends and then measured that there were 20 ounces leftover. How much coffee did Pedro make?
Answers
Answer:
Pedro made 54 ounces of coffee in total.
Step-by-step explanation:
Identify what you know:
1) Pedro gave his friend 34 ounces of coffee.
2) There was 20 ounces of coffee left over after!
So, we need to add the amount of coffee that his friend had, to the amount that's left, to get the total amount that he made.
Let's make an equation, where x equals the total amount!
34 + 20 = x
OR
x - 34 - 20 = 0
Hope this helps!
Answer:
54
Step-by-step explanation:
34+20= 54 ounces of coffee

Step-by-step explanation:
We have been given an equation . We are asked to write the missing exponent for our given equation.
We can see that 169 is square of 13, so we can write left side of our equation as:
We can raise 1 to any power and answer will be same.
Raising 1 to 2nd power, we will get:
Since both numerator and denominator is raised to 2nd power, so we can raise to 2nd power as:
Therefore, our missing exponent is 2.
