What is the answer for 438*1824

Answer: y

=

18

Explanation:

As

y

varies directly as

x

, we have

y

∝

x

. Also it varies inversely as square of

z

, which means

y

∝

1

z

2

.

Hence,

y

∝

x

z

2

or

y

=

k

×

x

z

2

, where

k

is a constant.

Now when

x

=

80

and

z

=

4

,

y

=

10

, so

10

=

k

×

80

2

=

k

k

Hence

k

=

5

=

2

and

y

=

2

x

z

2

.

So when

x

=

36

and

z

=

,

y

=

Step-by-step explanation:

Answer:

one angle = 162

another = 18

Step-by-step explanation:

one angle = x = 162

another angle = x - 144 = 162 - 144 = 18

x + x - 144 = 180

x + x = 180 + 144

2x = 324

x = 324/ 2 = 162

Answer:

12565.11 teeth approximately cut cross the cutting surface per seconds.

Step-by-step explanation:

Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).

The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw

Number of teeth on saw = 12 x 10π = 120π.

To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.

So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33

Therefore, we have

33.33 x 120π ≈ 12565.11 teeth

Answer: 10

Step-by-step explanation:

Question A:

The formula to find the hypotenuse is c²=a²+b²

So you would insert the numbers into the formula which would be c²=8²+6²

8²=64

6²=36

36+64=100

So c²=100

Then you want to find c on its own so you have to square root 100.

The square root of 100 is 10.

You have to use this method for the rest of the triangles.

The hypotenuse of the triangles are solved

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

a)

a = 8

b = 6

Now , From the Pythagoras Theorem , The hypotenuse² = base² + height²

c = √ ( 8 )² + ( 6 )²

c = √100 ≈ 10

b)

a = 11

b = 7

c = √170 ≈ 13.0

c)

a = 13

b = 6

c = √205 ≈ 14.3

Hence , the hypotenuse of the triangles are solved

Answer:

7n+700≥1,150 and 65 shirts

Step-by-step explanation:

The answer is 65 instead of 64 because there is a decimal of .287...

This means we have to round up in order to be correct, not down because then it wouldn't be enough.

The inequality represents the minimum number of shirts, n, the band must sell to earn the remaining money is, 7n + 700 > 1150.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

From, The given information le the number of t-shirts be 'n'.

Therefore, The inequality representing the minimum number of shirts, n, the band must sell to earn the remaining money is,

7n + 700 > 1150.

Answer:

The correct option is A: 4.29 N.

Step-by-step explanation:

The magnetic force is given by:

[tex] F = qv\times B = qvBsin(\theta) [/tex]

Where:

q: is the charge = 7.12x10⁻⁶ C

v: is the speed = c/2 = 1.5x10⁸ m/s

B: is the magnetic field = 4.02x10⁻³ T

θ: is the angle = 90° (the speed is perpendicular to the magnetic field)

Hence, the force on the charge is:

[tex]F = qvBsin(90) = 7.12 \cdot 10^{-6} C*1.5 \cdot 10^{8} m/s*4.02 \cdot 10^{-3} T = 4.29 N[/tex]

Therefore, the correct option is A: 4.29 N.

Answer:

Part A

= 9 flowers

Part B

= 5 flowers

Step-by-step explanation:

Emily has 59 flowers. She wants to put the flowers in 6 vases with the same number in each vase.

Part A: What is the greatest number of flowers she can put in each vase?

This is calculated as:

59 flowers ÷ 6 vases

= 9 5/6 flowers

Therefore, the greatest number of flowers she can put in each vase is 9 flowers

Part B: How many flowers will Emily have left over?

We have to calculate the number of flowers in the 6 vases above

= 9 flower × 6

= 54 flowers

Hence:

= 59 flowers - 54 flowers

= 5 flowers

Therefore, Emily would have 5 flowers left over.

Answer

[tex]C=2.5\pi[/tex]

Step-by-step explanation:

Radius is always half of the diameter so, [tex]\frac{2.5}{2} \\[/tex] is equal to [tex]1.25[/tex].

The Formula for Circumference is [tex]C=2\pi r[/tex]

Since we found out the radius, we need to basically substitute (or insert) it into the radius spot so the next step will be: [tex]C=2\pi (1.25)[/tex]

Then we multiply (2)(1.25) to get an answer of 2.5 (which we already know)

So our answer is going to be [tex]C=2.5\pi[/tex]
