Find the measure of WV¯¯¯¯¯¯¯¯¯. A. 8 B. 6 C. 7 D. 4

Answer:

2nd and 4th

Step-by-step explanation:

16.50÷6=2.75

So the second one is true.

12x2.75=33

So the fourth one is true.

Answer:

The first and fourth statements are true.

Step-by-step explanation:

We know that 6 pounds of blueberries costs $16.50 so 1 pound costs 16.5 / 6 = $2.75. Therefore, the first statement is true. The second statement can't be true because this is a direct proportion. In a direct proportion, when one variable increases, the other increases as well so the price of 2.75 pounds can't be less than the price of 1 pound. The cost of 5 pounds is 2.75 * 5 = 13.75 so the third statement is false. The cost of 12 pounds will be 2.75 * 12 = 33 so the fourth statement is true. The cost of 3 pounds is 2.75 * 3 = 8.25 so the fifth statement is false.

Question: In the following questions, look at different ways to represent the relation given by the equation y = x2 - 1. The table below shows some values for the given equation. Find the values of a and b.

Answer:

a= 3

b= 0

The value of a and be will be three and zero respectively.

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

We are given the quadratic equation as;

y = x² - 1

From the given table;

At x = -2, y =  (-2)² - 1 = 3

At x = -1, y = 0

At x = 0, y = -1

At x = 1, y = 0

Now, from the values above, we can say that the first graph is the correct one that shows some values for the given equation.

Therefore, values of a and be will be three and zero respectively.

Answer:

-5/4 0 6% 2/5 25% 6

Step-by-step explanation:

converting all to decimal -

.4, .06, 6, -1.25, 0, .25

Ok so we need to turn these all into the same type of number.

I'm going to turn it into decimals.

2/5 = 4/10 = 40/100 = 0.40

6%=0.06

6=6.00

-5/4 = -125/100 = -1.25

0 = 0.0

25% = 0.25

So now we order from least to greatest.

0.4, 0.06, 6, -1.25, 0, 0.25

Since -1.25 is a negative number, it goes first.

All of them except for -1.25 and 0 are positive numbers so 0 goes next.

Now you could ignore the decimal point; 40, 6, 600, 25

From least to greatest it is; 6, 25, 40, 600

So the final order from least to greatest is; -1.25, 0, 0.06, 0.25, 0.4, 6

Or; -5/4, 0, 6%, 25%, 2/5, 6

Answer:

The correct option is;

W

Step-by-step explanation:

The number of points that defines a plane in a Euclidean space in all dimensions is either three points which are not on the same line, or two colinear points and a third point not on the line

The given points of the plane are UVX, which gives the plane as being diagonal to the cube and perpendicular to the side face of the cube.

The fourth point in plane UVX is therefore W.

Answer:

160 m

Step-by-step explanation:

you can approach this question with the thinking of simple math. First, you have the value of -85 rose by 30 means +30 and descending 105 means -105.

So, the calculation you will get is -85+30-105=-160. The negative means going down as the direction.

Answer:

The maximum height of the particle is 484 m.

Step-by-step explanation:

Given that,

A particle is moving along a projectile path at an initial height of 160 feet with an initial speed of 144 feet per second. This can be represented by the function :

[tex]H(t) = -16t^2 + 144t + 160[/tex] ....(1)

We need to find the maximum height of the particle. For maximum height put [tex]\dfrac{dH}{dt}=0[/tex]

So,

[tex]\dfrac{d(-16t^2+144t+160)}{dt}=0\\\\-32t+144=0\\\\t=4.5\ s[/tex]

Put t = 4.5 s in equation (1) as :

[tex]H(t) = -16(4.5)^2 + 144(4.5)+ 160\\\\H(t)=484\ m[/tex]

So, the maximum height of the particle is 484 m.

Answer:

484 feet

Step-by-step explanation:

First, look at H(t) = −16t^2 + 144t + 160 as ax^2 + bx + c

Second, write out a=, b=, c=, which are a=-16, b=144, c=160

Third, plug a, b, & c into the equation for vertex which is t= -b/(2a) or t=-144/[2*(-16)], t=4.5.

Fourth, plug t=4.5 into the original equation H(t) = −16t^2 + 144t + 160, so H(4.5)=−16((4.5)^2) + 144(4.5) + 160 = -324 + 648 +160 = 484 feet

Step-by-step explanation:

2/3=4/6=6/9

your answer is 4/6,6/9

explanation

(2/3)×2=4/6

therefore 4/6 is a multiple of 2/3

(2/3)×3=6/9

therefore 6/9 is a multiple

if we comprise 4/6 & 6/9 we get 2/3

(b) 6/9 and (c) 4/6 are equivalent to 2/3

The fraction is given as:

[tex]\mathbf{Fraction = \frac 23}[/tex]

The equivalent fractions are 6/9 and 4/6, because they can be reduced to 2/3.

The proof is as follows

[tex]\mathbf{Fraction = \frac 69}[/tex]

Divide the numerator and the denominator by 3

[tex]\mathbf{Fraction = \frac{6/3}{9/3}}[/tex]

[tex]\mathbf{Fraction = \frac{2}{3}}[/tex]

Also, we have:

[tex]\mathbf{Fraction = \frac 46}[/tex]

Divide the numerator and the denominator by 2

[tex]\mathbf{Fraction = \frac 23}[/tex]

Hence, 6/9 and 4/6 are equivalent to 2/3

Answer:

Average Velocity= 70 miles per hour

Step-by-step explanation:

Distance= s

Time = t

s(t)=10t^2

Putting the values

s(2) = 10 (2)^2= 10&4

s= 40

s(5) = 10 (5)^2 = 10*25

S(5)= 250

The average velocity is defined as the rate of change of speed in unit time.

So

Speed= distance/time

Velocity = Speed in a definite direction

Average Velocity= Displacement/ Time

Average Velocity= Change in distance/ Change in time

s(5) - s(2)/ t(5)- t(2)

= 250-40/5-2= 210/3= 70 miles per hour

Answer:

No. of balloons left with Tarun is MORE than 10

but LESS than 15.

10 < No. of balloons left with Tarun  <15

Step-by-step explanation:

this is problem of inequality . first we will try to write the existing condition in inequality form then apply other situation as given in the problem.

___________________________________________________

let the no . of balloons with Tarun be x

Given  he has is MORE than 15 balloons

thus, in equality it can be represented as

x > 15

he has LESS than 20 balloons

x < 20

combining both we have

15   < x < 20

now he gives 5 of them to sia

so we have to subtract 5 from inequality

he has left with him x-5 , let x-5 be y

thus,

subtracting 5 from each part of inequality

15  -5 < x-5 < 20 -5

10 < x-5 < 15

10 < y <15

Thus, No. of balloons left with Tarun is MORE than 10

but LESS than 15.

Answer:

The first digit would go in the tens place.

Step-by-step explanation:

First we estimate the approximate numbers. For 6130 we estimate 6000 and for 153 we estimate almost 150.

So dividing 6000 by 150 would give 40 .

The four would go in the ten's place .

Now check by dividing

         40.1     So the answer is correct. The quotient is 40.12.

Answer:

To cover the remaining ten kilometres and average 40 km/hr, the autonomous car must drive at infinite speed (light speed)

Step-by-step explanation:

The average speed = (The total distance)/(The total time taken)

The given parameters are;

The required average speed of the autonomous car = 40 km/hr

The average speed of the car during the first 20 km = 40 km/hr

The  average speed of the car during the next 10 km = 20 km/hr

Therefore, we have;

The time taken = Distance/Speed

The time taken by the car during the first 20 km = 20 km/40 km/hr = 0.5 hour

The time taken by the car during the next 10 km = 10 km/20 km/hr = 0.5 hour

Therefore, the amount of time elapsed = 0.5 hour + 0.5 hour = 1 hour

The distance covered = 30 km

Which gives;

To drive the remaining distance of 10 km the car has 0 hour left,

The speed of the remaining 10 km must therefore be 10/0 =  Infinite (speed).

To cover the remaining ten kilometres and average 40 km/hr, the autonomous car must drive at infinite speed.

Answer:

It will take 19 days from Sunday.

Step-by-step explanation:

You can use the equation 172 + 6d = 1 + 15d for this equation. 172 and 1 are how many items Jose and Biruk started with. 6d and 15d represent how many items they get a day. Here's how you can solve the equation:

172 + 6d = 1 + 15d

       -6d         -6d

        172 = 1 + 9d

           -1   -1

         171 = 9d

Answer:

£13

Step-by-step explanation:

Set up a system of equations where s represents the cost of one shirt and j represents the cost of one jumper:

2s + j = 29

s + j = 21

Multiply the bottom equation by -2 to solve by elimination by cancelling out the s variables:

2s + j = 29

-2s - 2j = -42

-j = -13

j = 13

One jumper will cost £13

Answer:

The Break Even point is the point at which the cost=revenue   14,980+20x=30x 14,980=10x 1,498=x   a. 1,498 units must be sold to break even. At $20 per unit, the dollar amount will be $29,960   b. The profit function is P(x)=R(x)-C(x) So P(x)=30x-(14,980+20x) If you want to solve for this equation just enter the value of x we found for the break even point to get the answer.
