Which equation can be used to solve for x
Answers
Answer:
(a) 7(x +3.5x) = 56
Step-by-step explanation:
You want an equation to solve for x, the length of a morning run, if the evening run is 3.5 times as long, and these runs total 56 miles when done every day of the week.
Daily runThe morning run is given as x.
The evening run is 3.5 times as long, so is 3.5x
The total mileage each day is (x +3.5x).
Weekly totalIn 7 days, the mileage will be 7 times the daily mileage. That total is given as 56 miles:
7(x +3.5x) = 56
How can I find the measure of each angle or arc in a circle
Answers
Given:
Find the measure of each angle or arc in a circle.
Explanation:
As we know,
The central angle of a circle is 360 degrees.
The central angle that subtends the arc also subtends the same degrees of the arc.
We have the formula to find the measure of angle (or arc) when the arc length (or angle) and radius are given.
The formula is,
\(\text{Arc length, }l=\frac{\theta}{360^{\circ}}\times2\pi r\)Here, r is the measure of the radius of the circle and θ ( in degrees) is the measure of the angle subtended by the radius.
If θ is measured in radians, then the formula of arc length becomes,
\(\text{Arc length, }l=\theta r\)Example:
1. If the radius of the circle is 7 m and the measure of the angle subtended by the radius is 90 degrees, then the arc length is,
\(\begin{gathered} l=\frac{90}{360}\times2\times\frac{22}{7}\times7 \\ l=11m \end{gathered}\)2. If the radius of the circle is 7 m and the measure of the arc length is 33m then the measure of the angle is,
\(\begin{gathered} 33=\frac{\theta}{360^{\circ}}\times2\times\frac{22}{7}\times7 \\ 33=\frac{\theta}{90^{\circ}}\times11 \\ \theta=\frac{90^{\circ}\times33}{11} \\ \theta=270^{\circ} \end{gathered}\)what is the solution to the equation:

\( \sf \longrightarrow \: 5 \bigg( \: \frac{n}{1} - \frac{1}{10} \bigg) = \frac{1}{2} \\ \)
\( \sf \longrightarrow \: 5 \bigg( \: \frac{10 \times n - 1 \times 1}{1 \times 10} \bigg) = \frac{1}{2} \\ \)
\( \sf \longrightarrow \: 5 \bigg( \: \frac{10n - 1}{ 10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: \:n = \frac{2 \cancel{0}}{10 \cancel{0}} \\ \)
\( \sf \longrightarrow \: \:n = \frac{1}{5} \\ \)
Answer:-
Answer:- D) n = ⅕ ✅To solve the equation \(\sf 5(n - \frac{1}{10}) = \frac{1}{2} \\\) for \(\sf n \\\), we can follow these steps:
Step 1: Distribute the 5 on the left side:
\(\sf 5n - \frac{1}{2} = \frac{1}{2} \\\)
Step 2: Add \(\sf \frac{1}{2} \\\) to both sides of the equation:
\(\sf 5n = \frac{1}{2} + \frac{1}{2} \\\)
\(\sf 5n = 1 \\\)
Step 3: Divide both sides of the equation by 5 to isolate \(\sf n \\\):
\(\sf \frac{5n}{5} = \frac{1}{5} \\\)
\(\sf n = \frac{1}{5} \\\)
Therefore, the solution to the equation \(\sf 5(n - \frac{1}{10})\ = \frac{1}{2} \\\) is \(\sf n = \frac{1}{5} \\\), which corresponds to option (d).

AC is not equal to CE based on the angle bisector theorem. The answer is: C. NO, you cannot use the angle bisector theorem to determine that AC = CE.
What is the Angle Bisector Theorem?According to the angle bisector theorem, when a line segment divides an angle of a triangle, the line segment also divides the opposite side but does so in such a way that the two segments are proportional to the other two sides of the triangle. However, the two segments are not congruent to each other.
In the diagram given below that shows the suspect, the police officer, and the 26th Street toward Cherry Street, the angle bisector divides the side opposite to the angle divided into AC and CE. Thus, their length cannot be ascertain to be congruent to each other, however, based on the angle bisector theorem, we can only prove that their length is proportional to the other two sides of the triangle.
Therefore, we can conclude as saying:

To match each measurement with its corresponding equal value.
We will resolve the measurements on the left to feet and compare them with the measurements on the right.
Convert 2 1/3 yards to feet
\(\begin{gathered} 1\text{ yards = 3 feet} \\ \frac{7}{3}\text{yards = 3 }\times\frac{7}{3}=7\text{ feet} \\ \end{gathered}\)So the first measurement on the left can be matched to the 2nd measurement on the right.
\(\begin{gathered} \text{Convert 102 inches to feet} \\ \end{gathered}\)\(\begin{gathered} 1\text{ inch = }\frac{1}{12}\text{ feet} \\ 102\text{ inches =}\frac{1}{12}\times102=8\text{ }\frac{1}{2}ft\text{ or 8 1/2 feet} \end{gathered}\)The second measurement on the left can be matched to the 4th measurement on the right.
\(\begin{gathered} \text{Convert 3 1/2 miles to feet} \\ 1\text{ miles = 5280 feet } \\ \frac{7}{2}\text{miles}=\text{ 5280 }\times\text{ }\frac{7}{2}=18,480\text{ feet} \end{gathered}\)The third measurement on the left can be matched to the 1st measurement on the right.
\(\begin{gathered} \text{Convert 4 1/2 miles to feet} \\ 1\text{ miles = 5280 feet} \\ \frac{9}{2}\text{miles}=5280\times\frac{9}{2}=23,760\text{ feet} \end{gathered}\)The fourth measurement on the left can be matched to the 6th measurement on the right.

Step-by-step explanation:
C.

Looks like you have typos in part B so I've rewritten it:
B.
(4 + 6i)(3 + 21i
=12 + 8i + 18i + 12i^2
= 12 + 8i + 18i - 12
= 26i
Also I think A is:
.13i+ 3i + 5i+ 5i
= 16i + 10i
= 26i.
The expression that are equivalent to 26i will be 13i + 3i + 5i + 5i and (7 + 12i) - (7 - 14i). Then the correct options are A and C.

C. (7 + 12i) - (7 - 14i) = 26i
D. (13i) (21) = 273i
E. 13 + i + 13 = 26 + i
The expression that are equivalent to 26i will be 13i + 3i + 5i + 5i and (7 + 12i) - (7 - 14i). Then the correct options are A and C.

volume of a sphere = ³, where ris 3 ㅠ the radius. Titanium has a density of 4.506 g/cm³. How many kilograms would a sphere of titanium with a radius of 11 cm weigh? Give your answer to 1 d.p.
Answers
After answering the presented question, we can conclude that As a radius result, a titanium sphere with a radius of 11 cm would weigh roughly 25.1 kg (rounded to 1 decimal place).
what is radius?In more modern parlance, the length of a circle or sphere is the same as its radius in classical geometry, which is one of the line segments from its centre to its circumference. The term was derived from the Latin word radius, which also refers to the spokes of a waggon wheel. The radius of a circle is the distance between its centre and any point on its periphery. It is usually denoted by "R" or "r." A radius is a line segment with one endpoint in the centre and one on the circle's circumference. The radius of a circle matches its diameter. The diameter of a circle is the segment that passes through its centre and has ends on the circle.
The formula for the volume of a sphere of radius "r" is:
V = (4/3)πr³
Substituting the specified radius value (r = 11 cm), we get:
V = (4/3)π(11)³ \sV = 5575.279 cm³
Now we must compute the weight of the titanium sphere, which can be found by multiplying its volume by its density:
Density = Volume Weight
Weight = 25121.811974 g Weight = 5575.279 cm3 4.506 g/cm3
When we divide 1000 by 1000 to convert grammes to kilogrammes, we get:
The weight is 25.121811974 kg.
As a result, a titanium sphere with a radius of 11 cm would weigh roughly 25.1 kg (rounded to 1 decimal place).
