Answer:
[tex]x = \frac{23}{22} [/tex]
Step-by-step explanation:
[tex]22x = 23 \\ \frac{22x}{22} = \frac{23}{22} \\ x = \frac{23}{22} [/tex]
Answer:
x = 23/22 = 1.045
Step-by-step explanation:
Solving a Single Variable Equation :
1.1 Solve : 22x-23 = 0
Add 23 to both sides of the equation :
22x = 23
Divide both sides of the equation by 22:
x = 23/22 = 1.045

In triangle ABC, a=√2, b=1, and measure of angle a=90. Find the measure of angle B.
Answer:
In the triangle ABC, A is the right angle; the side "a", opposite to the angle A, is the hypotenuse and side "b" is the leg.
√ (√2)²-1² = √2-1= √1= 1
according to the Pythagorean theorem.
It means that you have the right angled triangle with congruent legs; thus the triangle is isosceles.
Hence, the angles at the base (at the hypotenuse) are congruent and each is equal to 180°-90°/2 = 45°
Answer. The measure of the angle B is 45°.
Step-by-step explanation:
The required value of the angle B is obtained as 45°.
What are trigonometric ratios?The trigonometric ratios are defined for a right angled triangle.
The example of these ratios are sin, cos, tan, cosec, sec and cot.
The trigonometric ratios are useful in determining the heights and distances of the large objects.
The given problem can be shown in the form of diagram as below,
The measure of given sides and angle of the triangle are as below,
∠A = 90°, a = BC = √2 and b = AC = 1.
Use the trigonometric ratio to obtain,
Sin∠B = BC/AC
⇒ Sin∠B = 1/√2
⇒ ∠B = 45°
Hence, the measure of angle B is given as 45°.

Step-by-step explanation:
x^2 = 50
Take the square root of each side
sqrt(x^2) = ±sqrt(50)
x = ±sqrt(25*2)
We know that sqrt(ab) = sqrt(a) sqrt(b)
x = ±sqrt(25)*sqrt(2)

The volume of a cylinder:
[tex]V \approx 150.796[/tex] [tex]ft^3[/tex]
Step-by-step explanation:
To find the volume of a cylinder, you need the this formula:
[tex]V = \pi r^2h[/tex]
-Use the given height and radius for the formula:
[tex]V = \pi 4^2 3[/tex]
-Then, solve the formula:
[tex]V = \pi \times 4^2 \times 3[/tex]
[tex]V = \pi \times 16 \times 3[/tex]
[tex]V = \pi \times 48[/tex]
[tex]V = 48\pi \approx 150.796[/tex]
So, the volume of a cylinder is approximately [tex]150.796[/tex] [tex]ft^3[/tex] .
Mr. Blue drove from Allston to Brockton, a distance of 105 miles. On his way back, he increased his speed by 10 mph. If the journey back took him 15 minutes less time, what was his original speed?
Answer:
His original speed was 60 mph.
Step-by-step explanation:
The average speed formula is shown below:
speed = distance / time
For the first leg of the trip Mr. Blue drove at a speed of "x" mph, for a distance of 105 miles, therefore the time that took to complete the trip is:
time 1 = distance / speed
time 1 = 105 / x h
On the second leg of the trip Mr. Blue drove faster at a speed of "x + 10" mph, so the time it took him to complete the trip was 15 minutes less, therfore:
time 2 = time1 - (15/60) = (105/x) - 0.25 = (105 - 0.25*x)/x h
Applyint the time and speed from the second leg to the average speed formula we have:
x + 10 = {105/[(105 - 0.25*x)/x]}
x + 10 = 105*x/(105 - 0.25*x)
(x + 10)*(105 - 0.25*x) = 105*x
105*x + 1050 -0.25*x² - 2.5*x = 105*x
-0.25*x² -2.5*x + 1050 = 0 /(-0.25)
x² + 10*x - 4200 = 0
x1 = [-(10) + sqrt((10)² - 4*(1)*(-4200))]/2 = 60
x2 = [-(10) - sqrt((10)² - 4*(1)*(-4200))]/2 = -70
Since his speed couldn't be negative the only possible value was 60 mph.
Answer:
60 mph

The simplified form of an expression is StartFraction 1 Over 256 EndFraction t Superscript 28. Which expression was simplified?
A.(256 t Superscript negative 7 Baseline) Superscript 4
B.(4 t Superscript 28 Baseline) Superscript negative 4
C.(256 t Superscript negative 7 Baseline) Superscript negative 4
D.(4 t Superscript negative 7 Baseline) Superscript negative 4
Answer:
1/258 *(t^28)
= t^28 / 4^4
= t^28 4^-4
= (t^-7 * 4)^-4
= (4t^-7)^-4
The simplified form of an expression [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .
What is simplified form ?Simplified form a rational expression is considered simplified if the numerator and denominator have no factors in common.
We have,
[tex]\frac{1}{256} * t^{28}[/tex]
Now to simplify it,
Convert [tex]256[/tex] into a exponent form with a base.
i.e.
[tex]\frac{1}{4^4} * t^{28}[/tex]
Now,
Using the exponent rule;
[tex]\frac{1}{a^n}= a^{(-n)}[/tex]
So,
[tex]4^{-4}\ *\ t^{28}[/tex]
Now, simplify it more by taking common power of [tex]4[/tex] and [tex]t[/tex] ,
[tex](4\ *\ t^{-7})^{-4}[/tex]
⇒ [tex](4 t^{-7})^{-4}[/tex]
So, this is the simplified form of given expression which is given in option number [tex](D).[/tex]
Hence, we can say that the simplified form of an expression [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .

Today Aimee is 1/3 of Jamie's age. In 12 years, Aimee will be 50% of Jamie's age. How old will Aimee be next year? Please answer quickly, there are bonus points
Answer:
Next year Aimee will be 13 years old
Step-by-step explanation:
Let's call Aimee's age A, and Jamie's age J.
From the information given, we have that:
A = (1/3) * J
A + 12 = (1/2) * (J + 12)
Using the value of A from the first equation in the second one, we have:
J/3 + 12 = J/2 + 6
J/2 - J/3 = 6
J/6 = 6
J = 36
Now we can find A:
A = (1/3) * 36 = 12
So next year Aimee will be 13 years old
Answer:
Aimee will be 13 years old next year/
Step-by-step explanation:
A stands for Aimee, and J stands for Jamie.
A = (1/3) * J
A + 12 = (1/2) * (J + 12)
Using the value of A from the first equation in the second one, we have:
J/3 + 12 = J/2 + 6
J/2 - J/3 = 6
J/6 = 6
J = 36
Now we can find A:
A = (1/3) * 36 = 12
In conclusion, Aimee will be 13 years old next year.
