100 points ANSWER ASAP

Answer:

1

Step-by-step explanation:

We see that 1 + 1 = 2, while 1 * 1 = 1

So 1 gives a bigger answer when you add 1 to itself then when 1 is multiplied by itself

In the answer it is given that this is the only number for which this is correct, so there is not really a need to check for other options

but if you would want, you could just compute 2 till 9 and see that for example 2 + 2 = 4 and 2 *2 = 4, which are the same, so it is not a bigger number when added then when multiplied.

Answer:

Trip to town hall took 5 hours

Step-by-step explanation:

Distance traveled = Speed x Time

We know the return trip took 4 hours at 75 mph

So distance traveled from town hall to start = 75 x 4 = 300 miles

The distance from start to town hall is assumed to be the same.

So distance to town hall from start = 300 miles also

Time taken to travel 300 miles at 60 mph = 300/60 = 5 hours

Answer: C) 6cm

Step-by-step explanation:

6³= 6x6x6

6x6x6= 216

Answer:

Choice C: 6 cm

Step-by-step explanation:

The sides of a cube are all of equal length

If each side is a cm, then the volume = a x a x a = a³ cubic cm

So a = ∛V where V is the volume

Since we are given V = 216 cm³,

each side = ∛21 = 6 cm

Answer:

5<x<41

Step-by-step explanation:

Assume the unknown side to be x

By triangle inequality theorem

Difference of two known sides < x< Sum if two known sides

⇒23-18<x<23+18

⇒5<x<41

Therefore the possible values for unknown side x lies between 5 ft and 41 ft.

Because the lines have different slopes, we conclude that there is only one intercept, and thus, the system of linear equations has only one solution.

Remember that a system of equations has as many solutions as intercepts are when we graph both equations in the same coordinate axis.

Now, in this case, we have a system of linear equations:

y = m1*x + b

y = m2*x + b

Remember that linear equations are parallel only if the two lines have the same slope, in this case, we know that  m1 ≠ m2, so the slopes are different.

Then the lines are not parallel, which means that intersect only one time, so we conclude that the system of equations has one solution.

The driving time in hours for the remainder of Guenther's trip would be = 9.5 hours.

Average speed of a moving object is defined as the average change in distance divided by change in time.

The first distance covered by Guenther = 260 miles.

The time it took to cover the first distance= 5 hours.

The remaining distance = 494 miles

The time it will take to cover the remaining distance= X hours

But if , 260 miles = 5 hours

494 miles = X hours

Make X the subject of formula;

X hours= 494 × 5 / 260

X hours = 2,470 / 260

√x > x↑2

This is because, x↑2 is equal to -.4 and √x is equal to 0.1. This means x equals to 0.2

The solution is : The true inequality is √x > x³, Option C.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

Here, we have,

Given 0.5≤ x ≤ 0.7

According to the range of x, we will check which option is true

Let x = 0.6

A. x/3 > √x

If x = 0.6

∴0.6/3  >  √0.6 ⇒  0.2 > 0.77  ⇒ Wrong inequality

B. x³ > 1/x

If x = 0.6

∴ 0.6³ > 1/0.6  ⇒ 0.216 > 1.667  ⇒ Wrong inequality

C. √x > x³

If x = 0.6

∴ √0.6 > 0.6³  ⇒ 0.77 > 0.216  ⇒ True inequality

D. (x/3) > (1/x)

If x = 0.6

∴  0.6/3  >  1/0.6   ⇒ 0.2  > 1.667  ⇒ Wrong inequality

So, The true inequality is option C.

113 disproves the conjecture that all number ending in 3 are divisible by 3

Mathematicians use a set of precise rules called the "divisibility rules" to determine whether a given integer is divisible by a certain number or not. Examples of well-known divisibility tests range from 2 to 20. It enables us to calculate multiples and factors of numbers without having to use lengthy division. Applying the rules of divisibility, a person can determine if a number is divisible by another number or not.

Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3.

243 is divisible by 3 as its sum is 2 + 4 + 3 = 9 and 9 easily get divided by 3

113 is not divisible by 3 as its sum is 5 and 5 can not divided by 3

therefore ,

113 disproves the conjecture that all number ending in 3 are divisible by 3

a) 75.80 percentage of students will be scoring below 550 in a typical year.

b) 22.2 marks should be set by the engineering school setas a comparable standard on ACT math test.

Here we have been mentioned that in the recent years, sat maths exam scores have averaged 480 with standard deviation 100. the average and standard deviation for act mathematics scores are 18 and 6, respectively.

a) The percentage of the students scoring below 550 marks in a typical year is calculated as follows:

Let x be the SAT score

So, x follows normal distribution

Given above,

mean (μ) = 480

standard deviation (σ) = 100

we will find P ( x < 550)

We will use the excel function NORM.DIST to find the required probability

P(x < 550) = NORM.DIST[tex](550, 480, 100, TRUE)[/tex]

= 0.7580

= 75.80%

Hence the percentage of the students who are scoring below 550 in a typical year = 75.80%

b) We calculate the score to be set by the engineering school as a comparable standard on the ACT math test as follows:

Let Z be the ACT score

Z follows the normal distribution

Given above, μ = 18 and σ = 6

Let Z' be the ACT score comparable to the standard set for SAT

Then we need to find Z' such that P(Z < Z') = 75.80% = 0.758

From standard normal tables we get Y' such that

Z' = NORM.INV[tex](0.758, 18, 6)[/tex]

= 22.2

The ACT score that needs to be set by the college = 22.2 marks

Answer:

y = [tex]\frac{1}{4}[/tex] x -  [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{4}[/tex] x + 1 ← is in slope- intercept form

with slope m = [tex]\frac{1}{4}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

to find c substitute (6, - 2 ) into the partial equation

- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - 2 - [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]

The nights required by Quinn in order to knit a total of 70 centimeters of the scarf is equal to 35.

The number of nights required by Quinn in order to knit a total of 70cm of the scarf can be calculated using multiplication. Multiplication can be described as one of the four basic arithmetic operations in which we perform the repeated addition of the same number or value. This problem can be solved using cross-multiplication as follows;

2 nights = 4 cm of scarf

x nights = 70 cm of scarf

70 × 2 = 4(x)

140 = 4(x)

x = 140 / 4

x = 35

Therefore, Quinn will have to spend 35 nights knitting in order to knit a total of 70 centimeters of the scarf.

m = 5/7  is the slope of the line on the graph .

What is slope in plain ?

A line or a part of a line that connects two locations is said to have a slope, which is a measure of how steep it is.

The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises.

The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b.
