Answer 1

Answer:

Volume of left side cylinder will be less than the volume of right side cylinder.

Step-by-step explanation:

Volume of a cylinder is given by the formula,

Volume = πr²h

Here, r = radius of the circular base

h = Height of the cylinder

Volume of the left hand cylinder = π(b)²a

Volume of the right hand cylinder = π(a)²b

It's given in the question that a > b

Let the value of a = 3 and b = 2

Then the volume of left hand cylinder = π(2)²(3)

= 12π

Similarly, volume of right hand cylinder = π(3)²(2)

= 18π

Therefore, volume of left side cylinder will be less than the volume of right side cylinder.

Answer:

a) 126degrees

b) 47degrees

Step-by-step explanation:

The sum of two supplementary angles is 180 degrees.

Let the other angle be x

x + 54 = 180

x = 180 - 54

x = 126degrees

The supplement is 126degrees

b) The sum of two complementary angles is 90 degrees.

Let the other angle be y

y + 43 = 90

y = 90 - 43

y = 47degrees

Hence the complement is 47 degrees

The equation for the speed/distance
of a tornado is s = 93 log(d) + 65.
If the speed is 190 mph, what is the distance?

Answers

Step-by-step explanation:

S = 93 log (d) + 65; S = wind speed; d = distance traveled by tornado

A) tornado travels 130 miles = d; find S

S = 93 log10(130) + 65

S = 261.6 mph rounds up to 262 mph

Answer:

22 miles

Step-by-step explanation:

s = 93 log(d) + 65 and s = 19093 log(d) + 65 = 19093 log(d) = 125log (d) = 125/93log (d) = 1.344 (rounded)d = 10^1.344d = 22 miles (rounded)

20 fl ounce = 1 pt and 4 fl oz

Step-by-step explanation:

We want to convert fluid ounce to pint and fluid ounce

Mathematically;

Mathematically, 1 pint = 16 fluid ounce

Now we can write 20 fluid ounce as;

16 fl ounce + 4 fl ounce

Since 16 fl ounce is a pint, we have it that;

20 fluid ounce is 1 pt 4 fl oz

Janice bought an antique clock originally priced at $967 but on sale for 5% off. After 1% sales tax, what was the total cost?

Answers

Answer:

927.84

Step-by-step explanation:

The total cost of the antique clock that Janice bought is $927.82 approximately.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we have:

Original price of clock = $967Sale discount = 5% on original price1% sales tax on the discounted price

Total cost = (discounted price of clock)'s price + sales tax of discounted price.

Let d = discounted price of the clock

Then, we have:

[tex]d = $967 - \text{5\% discount on 967} \\\\d = 967 - \dfrac{967}{100} \times 5 = \$918.65[/tex]

1% sales tax on 'd' will be: [tex]\dfrac{d}{100} \times 1 = \$9.1865 \approx \$9.19[/tex]

Thus, we get:

Total cost of the clock ≈ 918.65 + 9.19 = 927.82 (in dollars)

Thus, the total cost of the antique clock that Janice bought is $927.82 approximately.

Answer:

c. x = 7-t; y = -1/(t -7)

Step-by-step explanation:

To find the parametric equation for x, use the equation for t and solve for x.

t = 7-x

x = 7 -t . . . . . . add x-t to both sides

To find the parametric equation for y, substitute the equation for x.

y = 1/x

y = 1/(7-t)

To make this match the available choices, we need to multiply numerator and denominator by -1.

y = -1/(t -7)

The parametric equations are ...

x = 7 -t; y = -1/(t -7) . . . . . . matches choice C

Answer: it is C

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 3y = - 15

0 + 3y = - 15

3y = - 15 ( divide both sides by 3 )

y = - 5

solution is (0, - 5 )

Answer:

C) The choir has a total of 100 members

Step-by-step explanation:

Histogram is the graphical representation of data with the use of bars of different heights.

From the histogram attached:

A) Number of people fro 46 to 73 years = 30 + 5 + 15 = 50

Total Number of people = 15 + 20 + 5 + 10 + 30 + 5 + 15 = 100

Therefore half of the people are from 46 to 73 years.

Therefore the statement that more than half of the people are from 46 to 73 years is wrong.

B) The histogram shows the number of members between each age range, it does not show the number of male and female members. Hence we cannot determine the number of male and female members.

C) Total Number of people = 15 + 20 + 5 + 10 + 30 + 5 + 15 = 100

The choir has a total of 100 members

D) Number of people less than 32 years = 15 + 20 = 35

Therefore the statement that exactly 20 members are less than 32 years is wrong

The solution is acute angles

Answer:

x = 4, y = -3

Step-by-step explanation:

Find the slope intercept form first (y = mx + b):

the one going down is y = -1/2x - 1 (slope is negative, down 1 over 2, and the y-intercept is at (0, -1) )

the one going up is y = 1/4x - 4 (slope is up 1 over 4, and the y-intercept is at (0, -4)

Convert them into standard form (Ax + By = C):

1st equation: multiply the entirety of both sides by 2 to get rid of the fraction:

2y = -1x -`2

add 1x to both sides: 1x + 2y = -2

2nd equation: multiply the entirety of both sides by 4 to get rid of the fraction:

4y = 1x - 16

subtract 1x from both sides: -1x + 4y = -16

Isolate a variable:

-x + 4y = -16

-x = -4y - 16

x = 4y + 16

Plug that into other equation:

1(4y + 16) + 2y = -2

6y + 16 = -2

6y = -18

y = -3

Substitute y into the isolated equation:

x = 4(-3) + 16

x = -12 + 16

x = 4

132+2x=180
