Step-by-step explanation: ummnmm i think 18
The proportion of the value is is 18/a = a/16 , A proportion is an equation that sets two ratios at the same value.
What is proportion ?A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)
If two ratios depict the same relationship, they are said to be proportionate. By writing two ratios as fractions and then reducing them, one can determine if they are proportionate. Your ratios are proportional if the reduced fractions are equal.
Given:
It is a similar triangle to the one in the example.
The hypotenuse measures 18 units in length.
The leg is a certain length.
The portion of the hypotenuse is 16 units long.
We must ascertain the ratio that was employed to calculate the value of a.
We will use the geometric mean leg rule to discover the ratio needed to calculate the value of a.
When using the "leg rule," we have;
hypotenuse/leg
leg/part
Substituting the values of hypotenuse, leg and part, we get;
18/a = a/16
Thus the proportion of the value is is 18/a = a/16
The complete question is :
Which proportion can you use to find the value of a?

$50 tool with 9.5% tax
Answer:
55.26
Step-by-step explanation:
Divide 50 by 9.5 to get the amount the tool will be taxed.
5.26
Add 50 to that to get the total
55.26
The tax rate charge on the tool that is worth 9.5% is $4.75. The total amount paid for the tool is $54.75
What is the tax rate charged on a piece of equipment?The tax rate charge on a piece of equipment follows a standard rate by tax charges organization in that geographical region.
Given that:
A tool is worth $50The tax rate charge = 9.5%= 9.5% × $50
= 0.095 × 50
= $4.75
The total amount paid for the tool is = $4.75 + $50 = $54.75

Answer:
Step-by-step explanation:
sin(0°) = 0
sin(90°) = 1
The values of sin0 and sin 90 are 0 and 1 respectively
Table and values of a functionGiven the following values of theta
Theta = 0 and 90 degrees
If theta = 0 dgrees
Sin (0) = 0
If theta = 90 degrees
Sin(90) = 1
Hence the values of sin0 and sin 90 are 0 and 1 respectively

The radius of the base to the right circular cone shown below is 5 inches, and the height of the cone is 7 inches. Solving which of the following equations gives the measure,θ, of the angle formed by a slant height of the cone and a radius?
Step-by-step explanation:
In right angled triangle
Tan = opposite side / adjacent side
Opposite side = 7 inches
Adjacent side = 5 inches
Tan = 7/5
Trigonometric function is the ratio of the different sides of the triangle. The correct value of Tanθ is 7/5.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
We know that the value of the perpendicular height of the cone is 7 inches while the measurement of the base of the triangle is 5 inches, therefore, using Pythagoras theorem the third side of the triangle can be written as,
[tex]\rm(Slant\ Height)^2 = 7^2 + 5^2\\\\(Slant\ Height)^2 =49+25\\\\(Slant\ Height)= 8.6[/tex]
Now, the value of the trigonometric ratios can be written as,
[tex]\rm Sin \theta=\dfrac{7}{8.6}\\\\\\Cos \theta=\dfrac{5}{8.6}\\\\\\Tan \theta=\dfrac{7}{5}\\\\\\Cosec \theta=\dfrac{8.6}{7}\\\\\\Sec \theta=\dfrac{8.6}{5}\\\\\\Cot \theta=\dfrac{5}{7}\\\\\\[/tex]
Hence, the correct value of Tanθ is 7/5.

We need to isolate x to one side I will do that on the left side so it looks cleaner, therefore I will first flip the equation.
xm+n-p=z
Now move the n and p to the right side
xm=z-n+p
