Answer 1

Answer:

Step-by-step explanation:

2x + 1 = 5x - 44

-3x + 1 = -44

-3x = -45

x = 15

2(15) + 1 + 5(15) - 44

the curved surface of a cylindrical surface is 704 cm square calculate the height when the radius is 8cm​

Answers

Answer:

CSA of cylinder = 704cm²

We know that

CSA of cylinder = 2πrh

or 2πrh = 704

or, 2*22/7 *8 *h = 704 ( since r=8cm)

or, 352h = 704*7

or, h = 4928/352 = 14cm

when compared to the exact value?
A. 1,700
B. 2,000
C. 1,755
D. 1,800

Answers

Answer:

1755

there are 5280 feet in a mile, and there are 3 feet in a yard. if you divide 5280÷3 that will show you how many yards are in a mile. That will give 1760. Then you choose the number that is closest to that.

What is the value of x in the equation 0.3x = 12?

Answers

Answer:

You divide 0.3 by 12 if you don’t want a decimal do it the other way around the answer is x=40

Step-by-step explanation:

The value of x that satisfies the equation 0.3x = 12 is 40.

We have,

To find the value of x in the equation 0.3x = 12, we need to isolate x on one side of the equation.

We can do this by dividing both sides of the equation by 0.3, which will cancel out the coefficient of x on the left side:

(0.3x) / 0.3 = 12 / 0.3

Simplifying this equation gives:

x = 40

Thus,

The value of x that satisfies the equation 0.3x = 12 is 40.

Find the exact sum of the arithmetic series

6+3.8+⋯−29.2

Answers

Answer:

-197.2

Step-by-step explanation:

Since it is arithmetic series, first find the difference d between the two know series.

3.8 - 6 = - 2.2

d = -2.2

a = 6

Tn = -29.2

Looking for the n term, use the linear method.

Tn = a+( n - 1)d

Substitute all the parameters

-29.2 = 6+( n - 1 ) -2.2

-29.2 = 6 - 2.2n + 2.2

- 29.2 = 8.2 - 2.2n

-29.2 - 8.2 = - 2.2n

-37.4 = -2.2n

n = 37.4/ 2.2

n = 17 terms.

To Find the exact sum of the arithmetic series, use the sum formula below

Sm = n/2( 2a + (n - 1)d)

Sm = 17/2( 2 × 6 + ( 17 - 1 ) -2.2

Sm = 17/2(12 - 35.2)

Sm = 8.5( - 23.2)

Sm = - 197.2

Therefore, the exact sum of the arithmetic series is -197.2

Why does the solution for an absolute value equation or inequality typically result in a pair of equations or inequalities?

Answers

And represents the distance between a and 0 on a number line. Has two solutions x = a and x = -a because both numbers are at the distance a from 0. This holds true for all absolute value inequalities. ... Because by definition, the absolute value of a number is its distance from 0 on a number line which means that there are two such numbers: a positive/negative number

Why the solution for an absolute value equation or inequality typically result in a pair of equations or inequalities?

Because the absolute value equations behave differently in the different ranges.

For a given absolute value equation (or inequality)

| x - a| = b

We get two equations or inequalities:

x - a = b

x - a = - b

And this is why the solution leads to two equations, this originates in the fact that the parent absolute value function:

f(x) = |x|

Behaves differently if x is positive or negative.

f(x) = x if x > 0f(x) = -x if x < 0

(a) An angle measures 64°. What is the measure of its complement?



(b) An angle measures 145º. What is the measure of its supplement?

Answers

Answer:

(a) 26 degrees

(b) 35 degrees

Step-by-step explanation:

(a) complementary angles add up to 90 degrees, therefore the complementary angle to 64 degrees would be 90 - 64, or 26 degrees.

(b) supplementary angles add up to 180 degrees, therefore the supplementary angle to 145 degrees would be 180 - 145, or 35 degrees.

Question 3. The smallest digit by
which *' should be replaced in
710*95, so that the number formed is
divisible by 3 is:​

Answers

Answer:

2

Step-by-step explanation:

Given:

710*95

Find the smallest digit by

which * should be replaced, so that the number formed is

divisible by 3

The first step is to add the numbers

7 + 1 + 0 + * + 9 + 5 = 22 + *

Next step is to find the multiples of 3

3 = 6, 9, 12, 15, 18, 21, 24, 27, 30

Step 3:

Since the addition of the digits = 22 + *

Then find a number to add to 22 which gives the next multiples of 3 after 22(that is 24)

24 = 22 + *

* = 24 - 22

= 2

* = 2

Substituting * = 2 into 710*95

We have,

710295

Therefore, the smallest digit by

which * should be replaced, so that the number formed is

divisible by 3 is 2
