How Do You Do This With Decimals

Answers

Answer 1
Answer: x=102


Steps:

This is an isosceles triangle which mean 2 angles and 2 sides are congruent. In this case, the 3.3 sides corresponds to the 39 degree angle. This means that the other angle next to x angle is also 39 degrees.

39+39= 78

All the angles in the triangle needs to equal 180.

So subtract 78 from 180 to find the degree of x angle.

180-78= 102

16 and what other number is the geometric mean of 32

Answers

Answer:

16 and 64

Step-by-step explanation:

The geometric mean n of two numbers a and b can be given as;

√ab = n

In this question;

a = 16

b = ?

n = 32

So we have

16 * b = 32^2

b = 32^2/16

b = (32 * 32)/16

b = 2 * 32

b = 64

n/15=21/35 Solve for the missing value in the proportion.

Answers

Answer:

n=9

Step-by-step explanation:

21/35 has a gcf of 7. so reduce to 3/5

move 3/5 to the left side to get

n/15=-3/5=0

solve as a linear equation.

n/15=-3/5=0 is equivalent to .67*n-0.6=0

which is equal to n=-9

Find the selling price of a suit if a store
paid $140 for it, and it was marked up 80%
over the cost.

Answers

I think you multiply 140 and 80% and then add thst to the 140

Answer:

$252

Step-by-step explanation:

The store paid $140 for the suit. Let's first find the 80% of $140.

$140 x 80% = $112

So now we just need to add $112 to $140.

$140 + $112 = $252

-Okay so, we know that The lateral surface area of a prism is the sum of the areas of its lateral faces. And The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Then Usually, if "right" or "oblique" is not mentioned, you can assume the prism is a right prism.

Answer:

cos57° = x/51

General Formulas and Concepts:

Trigonometry

[Right Triangles Only] sin∅ = opposite over hypotenuse [Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use trig to solve for the missing side length.

Step 2: Set up ratios

We can choose between the 2 angles and have multiple ratios to solve for x.

sin33° = x/51

cos57° = x/51

Hence, we see that the 1st option would be the correct answer.

the coordinates of 3 points are a(-1, -6), b(3, -12) and c(k, 6). Find the value of k if a, b and c are collinear.

Plz answer quickly and step by step.

Answers

Answer:

The value of [tex]k[/tex] is -9.

Step-by-step explanation:

If [tex]A(x,y) = (-1,-6)[/tex], [tex]B(x,y) =(3, -12)[/tex] and [tex]C(x,y) = (k,6)[/tex], then [tex]\overrightarrow{BC} = \alpha\cdot \overrightarrow{BA}[/tex]. By vectors sum, we find each vector below:

[tex]\overrightarrow{BA} = A(x,y)-B(x,y)[/tex] (1)

[tex]\overrightarrow{BA} = (-1,-6)-(3,-12)[/tex]

[tex]\overrightarrow{BA} = (-4, 6)[/tex]

[tex]\overrightarrow{BC} = C(x,y)-B(x,y)[/tex] (2)

[tex]\overrightarrow{BC} = (k,6)-(3,-12)[/tex]

[tex]\overrightarrow{BC} = (k-3, 18)[/tex]

By substituting in the equation defined at the begining of this answer:

[tex](k-3, 18) =\alpha\cdot (-4, 6)[/tex]

[tex](k-3, 18) = (-4\cdot \alpha, 6\cdot \alpha)[/tex] (3)

The value of [tex]\alpha[/tex] is:

[tex]6\cdot \alpha = 18[/tex] (3a)

[tex]\alpha = 3[/tex]

If we know that [tex]\alpha = 3[/tex], then the value of [tex]k[/tex] is:

[tex]k-3 = -4\cdot \alpha[/tex]

[tex]k = 3-4\cdot \alpha[/tex]

[tex]k = 3-4\cdot (3)[/tex]

[tex]k = 3-12[/tex]

[tex]k = -9[/tex]

Then, the value of [tex]k[/tex] is -9.

vegetable ghee is stored in the cylindrical vessel of internal radius 1.4m height 1.5m. if it is transferred into the rectangular tin cans 33cm * 10cm*5cm how many cans are required to empty the vessel

Answers

Answer:

5,598 cans are required to empty the vessel

Step-by-step explanation:

The volume of a cylinder of radius r and height h is:

[tex]V = \pi r^2h[/tex]

The volume of a box of dimensions X, Y, and Z is:

V=X.Y.Z

A cylinder of r=1.4 m and height h=1.5 is used to store vegetable ghee. It contains a volume of:

[tex]V_1 = \pi 1.4^2*1.5[/tex]

[tex]V_1=9.236\ m^3[/tex]

Converting to cubic cm:

[tex]V_1=9.236*1,000,000\ cm^3[/tex]

[tex]V_1=9,236,282\ cm^3[/tex]

The volume of each rectangular tin can is:

[tex]V_2=33*10*5=1,650\ cm^3[/tex]

[tex]V_2=1,650\ cm^3[/tex]

The number of cans required to empty the vessel is:

[tex]V_1/V_2=9,236,282/1,650 = 5,598[/tex]

5,598 cans are required to empty the vessel

What is the length of the hypotenuse?
C =
miles

Answers

Answer:

The hypotenuse is 55 miles

Step-by-step explanation:

Given the sides of a right angle triangle as 33 and 44 miles, we want to get the hypotenuse

Mathematically, by Pythagoras’ theorem, the hypotenuse square is the sum of the squares of the other two sides

So we have;

h^2 = 33^2 + 44^2

h^2 = 3025

h = √3025

h =55 miles
