Answer:

  yes

Step-by-step explanation:

When distance and time are both zero at once, and speed is constant, then distance and time are proportional:

  distance = speed × time

The constant of proportionality is the (constant) speed.

Answer:

1/2 rational exponent represents a square root.

Therefore, option A is correct.

Step-by-step explanation:

As we know that raising to the one-half power i.e. [tex]\frac{1}{2}[/tex] is the same

as taking the square root.

For example, taking the square root of 4 will determine:

[tex]4^{\frac{1}{2}}[/tex]

[tex]\mathrm{Factor\:the\:number:\:}\:4=2^2[/tex]

[tex]4^{\frac{1}{2}}=\left(2^2\right)^{\frac{1}{2}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]

[tex]\left(2^2\right)^{\frac{1}{2}}=2^{2\cdot \frac{1}{2}}[/tex]

so the expression becomes

[tex]4^{\frac{1}{2}}=2^{2\cdot \:\frac{1}{2}}[/tex]

    [tex]=2^1[/tex]

    [tex]=2[/tex]         ∵ [tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a[/tex]

so, 1/2 rational exponent represents a square root.

Therefore, option A is correct.

Answer:

D.) -14 + 2i and 10√2

Step-by-step explanation:

Got it right on Edge

A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit. The correct option is D.

A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit, and satisfies the equation i² = -1; every complex number may be represented as a + bi, where a and b are real numbers.

To find the conjugate of a complex number, we change the sign of the complex part of the number. Therefore, the conjugate of -14-2i is -14+2i.

The modulus of the given complex number -14-2i is,

|z| = √[(-14)²+(-2)²]

    = √(196 + 4)

    = √200

    = 10√2

Hence, the conjugate and modulus of –14 – 2i are -14+2i and 10√2, respectively.

Answer:

31 Supreme tires were sold.

Step-by-step explanation:

Cost of one Supreme tire = $45

Cost of one Prestige tire = $56

Total sales = $2008

Let x represent quantity of supreme tyre

Let y represent quantity of Prestige tyre

So, the equation will be:

[tex]45x+56y=2008[/tex]

11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.

So, we are given y= 11 and we need to find value of x using above equation

[tex]45x+56y=2008\\45x+56(11)=2008\\45x+616=2008\\45x=2008-616\\45x=1392\\x=\frac{1392}{45}\\x=30.933\\ x\approx31[/tex]

So, 31 Supreme tires were sold.

Answer:

54

Step-by-step explanation:

Mike saves $36 by buying the shirts at a discounted price.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

Given the offer,

By 1 at regular price ($45) and get 40% off on two shirt

40 % of 45 ⇒ 0.40 × 45 = $18

So shirt price = 45 - 18 = $27/each

Since 2 shirt buy at this price = 2 × 27 = $54

Money saved = 2×45 - 54 = $36

Hence "Mike saves $36 by buying the shirts at a discounted price".

Given question is incomplete complete question is ;

Answer:

21

Step-by-step explanation:

21 + 21 = 42

42 + 12 = 54

so 21 is your answer

Answer:

21.

Step-by-step explanation:

For questions like this, it's easiest to work your way backwards from the answer to get the original number.

In this case, you subtract 12 from 54, which gives you 42 (54-12=41)

Then, you divide by 2, the opposite of "doubling". 42 ÷ 2 = 21.

Since there are no other operations, your original number is 21.

To confirm, just go through the problem again starting with 21 and seeing if you get to 54.

21, doubled (42), add 12 = 54.

Answer:

X=140

Step-by-step explanation:

Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees

The attachment you are showing us shows that we already know two angles

(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360.

X+70+60+90=360

X=360-70-60-90

X=140

This will be 12/20

Step-by-step explanation:

You take the number of favourable outcomes (12, as there are 12 boys) and take the number of total outcomes (20, as there are 20 people in total). Then you do the number of favourable outcomes over the number of total outcomes. This equals 12/20. I hope this helps

A fraction is a part of a whole.

It is expressed as a quotient, in which the numerator is divided by the denominator.

The fraction for boys out of 20 students is 3/5.

A fraction is a part of a whole.

It is expressed as a quotient, in which the numerator is divided by the denominator.

Example: 2/3, 5/7, 1/3

We have,

Total number of students = 20

Number of boys = 12

The fraction of the boys is:

= Number of boys / Total number of students

= 12 / 20

We can write along with its common factors.

= 2 x 6 / 2 x 10

Common values are canceled out from the numerator and the denominator.

= 6 / 10

We can write it as along with its common factor.

= 2 x 3 / 2 x 5

Common factors are canceled out from the numerator and the denominator.

= 3/ 5

Thus the fraction for boys out of 20 students is 3/5.

Answer:

The possible lengths of TR : TR = 17, 40, 42, 52,

Step-by-step explanation:

Given: Triangle WTR with WT = 25 and WR = 40. Identify all possible lengths for TR.

To find the possible lengths of the third side of a triangle:

c - a< b > a + c

a = WT = 25

c = WR= 40

b = TR = ??

40 - 25 < b < 40 + 25

15 < b < 65

The possible lengths of TR has to be greater than 15 and less than 65, Hence: TR = 17, 40, 42, 52,

Given:

In figure, ΔDEF has two equal angles ∠E and ∠F.

[tex]DE=40,EF=6x+10,DF=8x-24[/tex]

To find:

The incorrect statement from the given options.

Solution:

In triangle DEF,

[tex]\angle E=\angle F[/tex]            (Given)

[tex]DF=DE[/tex]            (Base angles are equal, so it is an isosceles triangle)

[tex]8x-24=40[/tex]

[tex]8x=40+24[/tex]

[tex]8x=64[/tex]

Divide both sides by 8.

[tex]x=8[/tex]

Now,

[tex]DE=DF=40[/tex]        (Isosceles triangle)

[tex]EF=6x+10[/tex]

[tex]EF=6(8)+10[/tex]

[tex]EF=48+10[/tex]

[tex]EF=58[/tex]

Therefore, x=8, FE=58, DE =40 and DF = 40.

Hence, the incorrect statement is in option B. So, option B is correct.

An isosceles triangle has two equal opposites sides

The correct statements are

A. FE = 58

A. FE = 58C. x = 8

A. FE = 58C. x = 8D. DF = 40

incorrect statement is

B. DE = 58

Given:

Side DE = 40

Side FE = 6x + 10

Side DF = 8x - 24

Recall,

DF = DE

8x - 24 = 40

8x = 40 + 24

8x = 64

x = 64 / 8

x = 8

Therefore,

Side FE = 6x + 10

= 6(8) + 10

= 48 + 10

= 58

Side DF = 8x - 24

= 8(8) - 24

= 64 - 24

= 40

Answer:  X=-4

Step-by-step explanation:

Answer:

y = - 0.8

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when y = - 4, x = 10, then

- 4 = 10k ( divide both sides by 10 )

- 0.4 = k

y = - 0.4x ← equation of variation

When x = 2 , then

y = - 0.4 × 2 = - 0.8
