Answer:
x = 1
Step-by-step explanation:
h(x) = -2x + 5 and h(x) = 3
which means -2x + 5 = 3
solve for x
-2x + 5 = 3
-5 -5
-2x = -2
-2 -2
x = 1

Answer:
The Answer is 12 - 15= 129
Step-by-step explanation:
x2−15=129
Step 1: Add 15 to both sides.
x2−15+15=129+15
x2=144
Step 2: Take square root.
x=±√144
x=12
After sitting out of a refrigerator for a while, a turkey at room temperature (69°F) is
placed into an oven. The oven temperature is 300°F. Newton's Law of Heating
explains that the temperature of the turkey will increase proportionally to the
difference between the temperature of the turkey and the temperature of the oven, as
given by the formula below:
T = Ta + (T. – T.)e-kt
Tg = the temperature surrounding the object
To = the initial temperature of the object
t= the time in hours
T = the temperature of the object after t hours
k = decay constant
The turkey reaches the temperature of 127°F after 3 hours. Using this information,
find the value of k, to the nearest thousandth. Use the resulting equation to
determine the Fahrenheit temperature of the turkey, to the nearest degree, after 5
hours.
Enter only the final temperature into the input box.

Answer:
1/2 ab sinC =1/2(5.5×12)sin33 = 17.97
Step-by-step explanation:
Put the numbers in the equation ,a calculator will be better.
The area of the triangle is 18.0cm².
What is the sine rule for the area of the triangle?The sine rule for the area of the triangle is defined as the area of the triangle that can be calculated by the product of the half of the two sides of the triangle and the sine of the angle between the two sides.
Area= Δ= (1/2)*a*b*sinC
where a and b are the length of the side BC and AC respectively. And angle C is the angle between the sides BC and AC.
Here given in the figure the triangle has two sides of lengths 12cm, and 5.5cm.
The angle between the sides is 33°.
Then using the sine rule for the area of the triangle
The area of the triangle= (1/2)*a*b*sinC
=(1/2)*12*5.5*sin 33°
=17.97≅ 18.0 cm²
Therefore the area of the triangle is 18.0cm².

38% of what number is 171?
Answer:
450
Step-by-step explanation:
We know that 171 is 38%, since they are trying to find the number which is 100%.
38% = 171
1% = 171 ÷ 38 = 4.5
100% = 4.5 x 100 = 450

A cylinder is shown below.
Answer: 244. 92 cm
Step-by-step explanation:
The surface area formula for a cylinder is written as SA = 2πrh + 2πr^2
The dimensions of the cylinder has a length of 6 cm diameter and a height of 10 cm. Radius is basically half of the diameter, so 3 cm. We use these numbers to substitute into the formula.
SA = 2π(3)(10) + 2π3^2
SA = 2π(30) + 2π(9)
SA = 60π + 18π
SA = 78π
SA = 245.044 cm
244.92 is close enough to 245.004, so 244.92 is the answer.

-2(6x - y) = -12x + 2y
-2(6x - y) = 12x + 2y
-2(6x - y) = 12x - 2y
-2(6x - y) = -12x - 2y
What’s the answer
Answer:
[tex]-2(6x - y) = -12x +2y[/tex]
Step-by-step explanation:
Required
Which shows distributive property
Distributive property states that:
[tex]a(b + c) = a * b + a * c[/tex]
So, the solution to -2(6x - y) is:
[tex]-2(6x - y)[/tex]
Open bracket
[tex]-2(6x - y) = -2 * 6x -2 *-y[/tex]
[tex]-2(6x - y) = -12x +2y[/tex]

The table below shows the amount of rainfall in Maryville during each week of April. What was the total amount of rainfall in the month of April?
Week 1: 2 2/3
Week 2: 1/8
Week 3: 1 3/4
Week 4: 1/2
Answer:
Step-by-step explanation:
Just add the fractions after finding the common denominator 3 times 8 = 24
Please check my math and typing for accuracy.
Week 1: 2 2/3 = 8/3 x 8/8 = 64/24
Week 2: 1/8 = 1/8 x 3/3 = 3/24
Week 3: 1 3/4 = 7/4 x 6/6 = 42/24
Week 4: 1/2 = 1/2 x 12/12 = 12/24
= (64+3+42+12)/24
= 121/24 24 times 5 = 120
= 5 1/24

How much is 2/9th of 234.900?
Given:
The number is 234.900.
To find:
The [tex]\dfrac{2}{9}[/tex]th of 234.900.
Solution:
We need to find the [tex]\dfrac{2}{9}[/tex]th of 234.900. So, multiply [tex]\dfrac{2}{9}[/tex] and 234.900 to get the required value.
[tex]\text{Required value}=\dfrac{2}{9}\times 234.900[/tex]
[tex]\text{Required value}=\dfrac{469.800}{9}[/tex]
[tex]\text{Required value}=52.200[/tex]
Therefore, the [tex]\dfrac{2}{9}[/tex]th of 234.900 is 52.200 or it can be written as 52.2.

Hay 12 canicas en una bolsa y 6
de ellas son verdes. Si se elige
una canica, ¿cuál es la
probabilidad de que sea verde?
Answer:
50%.
Step-by-step explanation:
Dado que hay 12 canicas en una bolsa y 6 de ellas son verdes, para determinar la probabilidad de que si se elige una canica al azar, esta sea verde, se debe realizar el siguiente cálculo:
6 / 12 = X
0.5 = X
0.5 = 50/100
50/100 = 50%
Así, hay un 50% de probabilidades de que, eligiendo una canica al azar dentro de la bolsa, la canica elegida sea verde.
