The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
What is the value of y when x 5 and z = 12?
A. 540
B. 9
C. 153
D. 450

Answers

Answer:

A

Step-by-step explanation:

Joint variation is given by:

[tex]y=kxz[/tex]

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

[tex]360=k(4)(10)[/tex]

Solving for k:

[tex]40k=360\Rightarrow k=9[/tex]

Therefore, our equation is:

[tex]y=9xz[/tex]

Then when x = 5 and z = 12:

[tex]y=9(5)(12)=540[/tex]

The answer is A.

Please help! (Geometry)

Answers

Answer:

x=5

From the dashed lines on the two sides of this triangle, we can see that these two sides are congruent, or equal, to each other.

In geometry, if a triangle has two congruent sides, then we can call it a isosceles triangle.

In an isosceles triangle, the corners  opposite the congruent  sides  are also congruent, meaning, that the angle measures of this triangle are: 88, 9x+1, and 9x+1.

We also know that angles in a triangle add up to 180 degrees.

So, we have: 88+(9x+1)+(9x+1) = 180

Simplifying: 18x + 2 = 92

Solving: 18x = 90, so x=5

Hope this helps!

Calculate the length AB

Answers

Answer:

14.004m

Step-by-step explanation:

Using the SOH CAH TOA trigonometry identity

Tan theta = opposite/adjacent

Given

AB = opposite

BC = adjacent = 20cm

theta = 35 degrees

Substitute

tan 35 = AB/20

AB = 20tan35

AB = 20(0.7002)

AB = 14.004cm

Hence the length of AB is 14.004m

At a restaurant, Julio's bill totals $37.60 (before tip). He leaves a 15% tip. Find the amount Julio left for tip.​

Answers

Answer:

$5.64 is left for tip.

Step-by-step explanation:

Given that,

The total bill of Julio = $37.60

He leaves a 15% tip.

We need to find the amount Julio left for the tip.​

The left amount can be calculated as follows :

[tex]L=15\%\ of\ 37.60\\\\=\dfrac{15}{100}\times 37.60\\\\=\$5.64[/tex]

So, Julio left $5.64 for tip.

Explain how to name a triangle using its sides and angle measures.

Answers

Answer:

a triangle using 3 sides and 3m angle measure

When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle. If all three sides are the same length, then it is an equilateral triangle.

Answer:

The bottom edge of the right triangle is: 16in -10in = 6in

So the area of the triangle is: S1 = 1/2 (a x b) = 24/2 = 12m2

the area of a square is: S2 = a ^ 2 = 10 ^ 2 = 100m2

The total area of the figure is: S1 + S2 = 12 + 100 = 112 m2
