Answer:

Volume of a cone = 50 in³

Step-by-step explanation:

diameter = 5 in

radius = 2.5 in

height = 8 in

Volume of cone = [tex]\frac{\pi r^2h}{3}[/tex]

V = (3 × 2.5 × 2.5 × 8)/3

V = 150/3

V = 50 in³

Actually Welcome to the concept of Lines.

We know that perpendicular lines have a inverse negative slope, such that

m1*m2 = -1

hence, m1 = -1/m2

so the perpendicular line is,

==> y-(5) = 3/2(x-(-6))

==> y+5 = 3/2(x+6)

==> y+5 = 3/2*(x) +9

=> y = 3/2(x) +9-5

==> y = 3/2*(x) + 4

hence the correct option is D.)

independent compound event definition

Answers

Answer:

Independent events occur when the outcome of one event does not affect the outcome of the second event. Rolling a four has no effect on tossing a head. To find the probability of two independent events, multiply the probability of the first event by the probability of the second event.

Other answer:

A compound event is the combination of two or more simple events (with two or more outcomes). Compound Probabilities (with more than one outcome (desired result) within a trial ): • The probability of rolling an even number less than 5 on a die. (

Which box of crackers is a better deal?
190 grams - $1.49
850 grams - $6.99
Explain your thinking.

Answers

Answer:

Since each cracker in the 190 gram box costs $ 0.0078 while the 850 gram box costs $ 0.0082 each, the 190 gram box is a better deal.

Step-by-step explanation:

Knowing that a 190-gram box of crackers costs $ 1.49 and an 850-gram box costs $ 6.99, to determine which of them is a better deal, the following calculation must be performed:

1.49 / 190 = 0.0078

6.99 / 850 = 0.0082

Therefore, since each cracker in the 190 gram box costs $ 0.0078 while the 850 gram box costs $ 0.0082 each, the 190 gram box is a better deal.

Answer:

1.05 × 1.05 × 1.05 × 1.05 × 1.05 = 1.2762815625

Step-by-step explanation:

An exponent indicates how many times the base is a factor in the product. That is, 1.05 to the 5th power means ...

1.05⁵ = 1.05 × 1.05 × 1.05 × 1.05 × 1.05

This multiplication expression is evaluated in the usual way.

= 1.1025 × 1.05 × 1.05 × 1.05

= 1.157625 × 1.05 × 1.05

= 1.21550625 × 1.05

= 1.2762815625

All complementary angles

The image is blur and the texts are unreadable. However, the following explanation will assist you

To determine a pair of complementary angles, then both angles must add up to 90.

For instance: 50 and 40; 72 and 18, 10 and 80 etc.

So, all you need to do is select all pairs of angles that add up to 90 in the given image.

Take for instance:

[tex]\angle ABC = 50[/tex] and [tex]\angle BDE = 40[/tex] -- assumed values

This means that, you will select [tex]\angle ABC\ \&\ \angle BDE[/tex] as a pair

The list price of an item is $550 and it is chain discount by 50%
less 10% less 20%. How much is the discount?
$352
$198
$440
$110

Answers

Answer:

$352

Step-by-step explanation:

first discount = 550 : 2 = $275

Second discount:

10 : 100 = x : 275

x = (2750/100) = $27,50

275 - 27,50 = $247,50

third discount

20 : 100 = x: 247,50

x = (247.50*20)/100 = $49,50

247,50 - 49,50 = $198 (final price)

total discount = 550 - 198 = $352

Write the equation for the function g(x), which can be described as a
vertical shift 13 units up from the function f(x) = In x –1

Answers

Answer:

Step-by-step explanation:

When you shift up or down, the function gets added to or subtracted from the expression on the right of the y value. Put in simpler language, for this question, the equation becomes.

g(x) = f(x) + 13

And the solution is

g(x) = ln(x) - 1 + 13

g(x) = ln(x) + 12

what value of x will make the faction equivent 3/5=x/36

Answers

Answer:

x = 21.6

Step-by-step explanation:

Solution by Cross Multiplication

For the equation

35=x36

The cross product is

3×36=5×x

Solving for x

x=3×365

and reducing

x=21.6

Solution by Proportion

Since the equation is an equality

36 ÷ 5 = 7.2

Then it is true that

x ÷ 3 = 7.2

Solving for x

x = 3 × 7.2

x = 21.6

i need help w this plz thanks

Answers

Answer:

x = 4√7

y = 8√7

Step-by-step explanation:

Reference angle = 60°

Opposite = 4√21

Hypotenuse = y

Adjacent = x

To find x, apply TOA

Tan 60 = Opp/Adj

Tan 60 = (4√21)/x

x * Tan 60 = 4√21

x = (4√21)/Tan 60

x = (4√21)/√3 (tan 60 = √3)

Rationalize

x = (4√21*√3)/√3*√3

x = (4√63)/3

x = (4*3√7)/3

x = 4√7

To find y, apply SOH:

Sin 60 = Opp/Hyp

Sin 60 = (4√21)/y

y*Sin 60 = 4√21

y = 4√21/sin 60

y = (4√21)/(√3/2)

y = ✓(4√21 × 2/√3)

y = (8√21)/√3

y = 8√7
