Answer:
Una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.
Step-by-step explanation:
De acuerdo con este problema, la cantidad de calorías que se quema es directamente proporcional al tiempo de viaje en bicicleta. Si sabemos que una galleta aporta 150 kilocalorías, entonces 5 galletas equivalen a 750 kilocalorías.
Por regla de tres simple calculamos el tiempo requerido para quemar 750 kilocalorías:
[tex]x = 30\,min \times \frac{750\,kcal}{150\,kcal}[/tex]
[tex]x = 150\,min[/tex]
Es decir, una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.

Answer:
y = 3
Step-by-step explanation:
3(2y-3) = -4y+21
6y-9 = -4y+21
10y-9 = 21
10y = 30
10y/10 = 30/10
y = 3

Consider angle θ in Quadrant lI, where cosθ = - 12/13. What is the value of sinθ?
Answer:
The value of sin Ф is [tex]\frac{5}{13}[/tex]
Step-by-step explanation:
In quadrant II, the value of
sin Ф is positivecos Ф is negativetan Ф is negativeLet us solve the question
∵ sin²Ф + cos²Ф = 1
∵ cos Ф = [tex]\frac{-12}{13}[/tex]
→ Substitute it in the identity above
∴ sin²Ф + ([tex]\frac{-12}{13}[/tex])² = 1
∴ sin²Ф + [tex]\frac{144}{169}[/tex] = 1
→ Subtract [tex]\frac{144}{169}[/tex] from both sides
∵ sin²Ф + [tex]\frac{144}{169}[/tex] - [tex]\frac{144}{169}[/tex] = 1 - [tex]\frac{144}{169}[/tex]
∴ sin²Ф = [tex]\frac{25}{169}[/tex]
→ Take the square root of both sides
∵ √(sin²Ф)= ± [tex]\sqrt{\frac{25}{169}}[/tex]
∴ sin Ф = ± [tex]\frac{5}{13}[/tex]
∵ Ф is in quadrant II
∴ sin Ф is a positive value
∴ sin Ф = [tex]\frac{5}{13}[/tex]
∴ The value of sin Ф is [tex]\frac{5}{13}[/tex]

Yes they are equivalent
In △XYZ, angle X is the smallest angle, angle Y is 40 degrees more than angle X, and angle Z is 2 times the measure of angle X. What is the measure of angle X?
Answer:
x=35° y= 75° z = 70°
Step-by-step explanation:
Y = x+40 (known)
z = 2x (known)
x + y + z = 180 (triangle property)
x + (x+40) + 2x = 180 (substitution)
4x + 40 = 180
4x = 140
x = 35
y = x + 40 = 75
z = 2x = 70

Wayne has a recipe that says to heat the oven to 160°C. Wayne evaluates the expression 1.8C + 32 when C= 160 to convert the temperature to degrees Fahrenheit To which temperature should Wayne heat the oven?
Wayne should heat the oven to a temperature of 320°F for a recipe.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.
Wayne has a recipe that says to heat the oven to 160°C.
To convert a temperature in degrees Celsius to degrees Fahrenheit, we can use the formula:
F = 1.8C + 32
Given that C= 160, we can substitute it into the formula:
F = 1.8(160) + 32
F = 288 + 32
F = 320
Therefore, he should heat the oven to 320°F.

Given a quadrilateral DEFG. If angle ED is supplementary to ____________then DEFG is a parallelogram .
A. angle EFG and angle DEF B. angle DGF and angle EFC C. angle DEF and angle DGF
Answer:
The correct option is A.
Step-by-step explanation:
It is given that DEFG is a parallelogram.
Draw the diagonals DF and EG. Place point H where DF and EG intersect.
In triangle HGD and HEF
,
∠HGD ≅ ∠HEF (Alternate Interior angle)
∠HDG ≅ ∠HFE (Alternate Interior angle)
By the definition of a parallelogram, the opposite sides of a parallelogram are congruent.
DG ≅ EF (Opposite sides of parallelogram)
According to ASA postulate :
two triangles are congruent if any two angles and their included side are equal in both triangles.
So, by using ASA criterion for congruence we get,
ΔDGH ≅ ΔFEH
Since corresponding sides of congruent triangles are congruent, therefore
GH ≅ EH (CPCTC)
DH ≅ FH (CPCTC)

Answer:Can u sum it up?
Step-by-step explanation:
Answer:
47
Step-by-step explanation:
Step-by-step explanation:
(Base1 + Base2)/2 = midsegment
1. ((2x+15) + (6x-37))/2 = 3x+5
2. (8X-22)/2 = 3x+5
3. ((8x-22)/2))2 = (3x+5)2
4. 8x-22=6x+10
5. 2x-22=10
6. 2x-22+22=10+22
7. 2x=32
8. x=16
Now that you have solved for X add the value to line RS
RS = 2(16) + 15
RS = 32 + 15
RS = 47

Use the equation below to find v, if u = 18, a=6, and t=4.
v=u+at
Answer:
v= 42
Step-by-step explanation:
To find the value of v, substitute the given values into the equation.
v= u +at
when u= 18, a= 6, t= 4,
v= 18 +6(4)
v= 18 +24
v= 42

A) there is 5 blue marbles out of 20 total marbles.
The probability of picking blue would be number of blue/ total marbles = 5/20 which can be reduced to 1/4
The answer is 1/4
B) the more marbles of a color would be a greater chance of picking it.
Green has the highest number of marbles so the answer is green.

what is the solution of the proportion?
x-6/4 = 2/4
a 9/2
b 5/2
c 21/2
d 18
Answer:
Solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex] is x=8.
Step-by-step explanation:
We need to find solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex]
For solving the equation, first we will multiply both sides by 4
[tex]\frac{x-6}{4}=\frac{2}{4}[/tex]
[tex]4\times \frac{x-6}{4}=4\times \frac{2}{4}[/tex]
[tex]x-6=4(\frac{2}{4})[/tex]
Simplifying
[tex]x-6=2[/tex]
Adding 6 on both sides
[tex]x-6+6=2+6x=8[/tex]
So, solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex] is x=8.
Note: Kindly recheck your options as correct answer is x =8.

What is the solution to the system of eqautions represented by these two lines?
Answer:
Step-by-step explanation:
A or C
Answer:
The solution to the system of equations represented by these two lines is:
(2, 0)Hence, option C i.e. (2, 0) is correct.
Step-by-step explanation:
Please note that the point of intersection between two lines is the solution of the system of equations.
From the graph, it is clear that two lines intersect at x = 2 and y = 0.
In other words, the point of intersection of the two lines is:
(x, y) = (2, 0)
Therefore, the solution to the system of equations represented by these two lines is:
(2, 0)Hence, option C i.e. (2, 0) is correct.

y = -5/4x + 2
Answer:
A
Step-by-step explanation:
graph calc
Answer:
y=-4/5x-2
Step-by-step explanation:
the y intercept is -2, because the line touches the y axis at -2. the line is the the 2nd and the 4th quadrant which make the slope negative. The rise is 4 and the run is 5, so its -4/5x.
systems of equations 5x+y=7
20x+2=y
Step-by-step explanation:
5x+y=7
20x+2=y
put y value in first equation
5x+(20x+2)=7
25x=5
x=5
now put x value to determine y
as we know 20x+2=y
20(5)+2=y
y=102

HELPPPP indentify one characteristic of exponential decay
Answer:
A more intuitive characteristic of exponential decay for many people is the time required for the decaying quantity to fall to one half of its initial value. This time is called the half-life, and often denoted by the symbol t1/2. The half-life can be written in terms of the decay constant, or the mean lifetime.
