Compare the square root of one hundred forty and one hundred three ninths using <, >, or =.

Answers

The square root of one hundred forty > the square root of one hundred three ninths

In this question, we need to compare the square root of one hundred forty and the square root of one hundred three ninths.

We write the square root of one hundred forty as,

√(140)

The value of the square root of one hundred forty is,

√(140) = 11.8 ..............(1)

We write the square root of one hundred three ninths as,

√(11.44)

The value of the square root of one hundred three ninths is,

√(11.44) = 3.4 ...................(2)

From (1) and (2),

11.8 > 3.4

i.e., the square root of one hundred forty is greater than the square root of one hundred three ninths

Therefore, the square root of one hundred forty > the square root of one hundred three ninths

If 6 is an element in the domain of f(x) =
7x - 16
5
what is the corresponding element in the range?
The corresponding element is (Simplify your answer.)

Answers

Answer:

When x=6 in the domain, then y=26 is the corresponding element in the range of the function f(x)=7x-16.

Step-by-step explanation:

Given the expression

[tex]f(x)=7x-16[/tex]

Given that x=6 is an element in the domain of f(x).

Substituting x=6 in the expression to find the corresponding element in the range.

[tex]f(6)=7(6)-16[/tex]

[tex]= 42-16[/tex]

[tex]= 26[/tex]

Thus, the corresponding element in the range is: y=26

Therefore, we conclude that:

When x=6 in the domain, then y=26 is the corresponding element in the range of the function f(x)=7x-16.

WILL GIVE BRAINLIEST! Find the equation of a line that passes through (-5,-2) and the intersection of the lines x+3y=0 and 4x-4y-13=0

Answers

Answer:

y + 2 = -0.069(x-+5)

Step-by-step explanation:

SInce the two lines intersects, we will equate it

Multiply x + 3y = 0 by 4;

4x + 12y = 0

4x-4y-13 = 0,

Subtracts both

12y +4y + 13 = 0

16y = 13

y = 13/16

get x;

x + 3(13/16) = 0

x = -39/16

The point of intersection is (0.8, -2.4) and (-5,-2)

Get the equation;

m = y2-y1/x2-x1

m = -2+2.4/-5-0.8

m = 0.4/-5.8

m = -0.069

Get the equation;

y - y0 = m(x-x0)

y - (-2)= -0.069(x-(-5))

y + 2 = -0.069(x-+5)

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $78. A season ski pass costs $350. The skier would have to rent skies with either pass for $25 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily pass?

Answers

Answer:

4 days

Step-by-step explanation:

to find this our you must add 78 and 25 before doing anything as they are both part of the daily pass rates

78 + 25 = 103

now you must divide 350 by 103

350/103 = 3.39805825

because you want to find when the season pass is less expensive than the daily pass you must round up

i think it might be A. because when you go in y=mx+b form for the line with a y-intercept of -5 you will have a decision between A and C but if you look at the second line it crosses the y-axis at 2. so I’m prettyyyyy sure it’s A but i’m so sorry if i’m not:(

12 boys should be enrolled to make the ratio into 1 : 1

What is a ratio?

'A ratio is a mathematical expression written in the form of a : b, where a and b are any integers. It expresses a fraction.'

According to the given problem,

Given ratio = 4:7

Total number of students = 44

Let the unknown integer multiplier be x,

⇒ 4x + 7x = 44

⇒ 11x = 44

⇒ x = 4

Number of boys = 4 × 4

= 16

Number of girls = 4 × 7

= 28

Therefore number of boys to be enrolled = 28 - 16

= 12

Hence, we can conclude, 12 boys should be enrolled with the already enrolled 16 so as to make boys : girls as 1 : 1.

Based on the angle addition postulate, the measure of angle 1 is calculated as: 88°.

What is the Angle Addition Postulate?

The angle addition postulate states hat the sum of two smaller angles is always the measure of a bigger angle from which the smaller angles are formed from.

Given:

Measure of angle 2 = 45°

Measure of angle XWY = 133°

Therefore:

Measure of angle 1 + 45 = 133 [angle addition postulate]

Subtract 45 from each side of the equation

Measure of angle 1 + 45 - 45 = 133 - 45

Measure of angle 1 = 88°

Therefore, based on the angle addition postulate, the measure of angle 1 is calculated as: 88°.
