PLEASE HELP ME!!! jacky starts biking to meet up with her friend. she knows that if she bikes at a speed of 10 mph, she will be 3 minutes late. jacky also know that if she bikes at a speed of 12 mph, she will be there 2 minutes before they agree to meet. how much time does she have left before the appointed time?
Answer:
27s
Step-by-step explanation:
d = distance to rendezvous point in miles
t = time of arrival at 10mph, i.e. 3 mins later than appointed time
10 mph = 10 miles per hour = ¹/₆ miles per min
12 mph = ¹/₅ miles per min
t = d/(¹/₆)
t = 6d
5 min = ¹/₁₂ hr
t - ¹/₁₂ = d/(¹/₅)
t = 5d + ¹/₁₂
Elimination of t:
6d = 5d + ¹/₁₂
d = ¹/₁₂ mi
t = 6(¹/₁₂)
t = ¹/₂ min
Time left to appointed time = ¹/₂ - ³/₆₀
= ¹⁰/₂₀ - ¹/₂₀
= ⁹/₂₀.min → 27 seconds
Answer:
27 min

If the number of molecules in 1 mole of a substance
is 6.02 x 1023, then the number of molecules in 100
moles is
Answer:
6.02 x 10^25
Step-by-step explanation:
6.02 x 10^23 molecules/ mole
In 100 moles
100 = 10^2
(6.02 x 10^23 molecules/mole) * (10^2 moles)
when multiplying numbers with the same base
add the exponents
6.02 x 10^25 molecules

if The cost of 4 burgers and 5 fries is $15.73 at Whataburger. Find the cost of
one burger and the cost of one order of fries at Whataburger if the burgers
cost 2 times as much as the fries.
Answer:
$2.42 For one Burger
$1.21 For one order of Fries
Step-by-step explanation:
4(2(x))+5x=15.73
Multiply the numbers: 4*2
8x+5x=15.73
Combine like terms: 8x+5x
13x=15.73
Divide both sides of the equation by the same term: 13

Answer:
b = 2Step-by-step explanation:
We know that:
a/b + c/d = (ad + bc)/bdWe observe the denominator of the first expression is same as the product of the denominators of the second expression.
Compare the numerators and solve for b:
5(x - 1) - 4(x - b) = x + 35x - 5 - 4x + 4b = x + 3x - 5 + 4b = x + 34b - 5 = 34b = 8b = 2Henry and his little brother made up a game using coins. They flip the coins towards a cup and receive points for every one that makes it in. Henry starts with 15 points, and his little brother starts with 20 points. Henry gets 3 points for every successful shot, and his brother, since he is younger, gets 2 points for each successful shot. Eventually, the brothers will have a tied score in the game. How many additional shots will each brother have made?
Write a system of equations, graph them, and type the solution.
Answer:
After 5 additional shots, the brothers will have a tied score.
Step-by-step explanation:
find equations
henry:
y-int is 15 because that is the starting number. the slope is 3 because that is how much his points are increasing for every successful shot. we can use this information to form this equation:
y = 3x + 15
brother:
y-int is 20 because that is the starting number. slope is 3 because that is how many points he gets for each successful shot. using this information, we can form the following equation:
y = 2x + 20
--
solve
y = 3x + 15
y = 2x + 20
3x + 15 = 2x + 20
x + 15 = 20
x = 5

Britton rotated trapezoid ABCD 180° on the coordinate plane. If angle B is 20° and angle D is 90°, what is the degree measurement of angle B′?
Group of answer choices
20°
70°
90°
180°
Answer:
20°
Step-by-step explanation:
Rotation is one of 3 basic rigid transformation, it will not change the original shape and size. Therefore angle B' should be still 20°
The degree measurement of angle B′ will be same as angle B that is 20°. Then the correct option is A.
What is a transformation of a shape?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.
From before the refers to the object's initial condition, and Picture, after transformation, refers to the object's ultimate structure and location.
Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.
If the geometry is rotated, then there is no change in anlges.
Britton rotated trapezoid ABCD 180° on the coordinate plane. If angle B is 20° and angle D is 90°.
The degree measurement of angle B′ will be same as angle B that is 20°.
Then the correct option is A.
