Answer: 11 Books, 6 Toys

Step-by-step explanation:

Let the number of books be B, and the number of toys be T

B+T=17

11B+6T=157

Let's use the elimination method:

11B+6T=157

6B+6T=102

And finally you get

5B=55

B=11

Use the value of B to get T

11+T=17

T=6

Therefore, the answer is

B=11,T=6

I graphed it out

value of p = 7 and value of q = 10.

The word consecutive implies an unbroken sequence that means terms approaches forward by following a specific order. Within a consecutive sequence the gap between each term is the same.

given, 4, p, q, 13 are consecutive terms, find the value of P and Q.

As the above four are consecutive number so starting from the 4 we write the list in an unbroken sequence.

At first difference between highest and lowest number = 13- 4 = 9

now this difference is divided by the number of gaps between the sequence, we find there are 3 gaps between four numbers.

order of sequence = 9/ 3 = 3

now the next number after 4 will be 4+3 = 7

in the next, 7+3 =10

finally, we get 10+3 =13

so, the consecutive numbers are 4, 7, 10, 13.

As a result, p = 7 and q = 10

We solved using elimination method, For the given set of equations, no solution exists.

To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

Given,

two equations as

60x-42y=0                                                          ........... (1)

-100x + 70y=0                                                     ............(2)

Now, multiplying the equation (1) by 10 and (2) with 6

we get the equation as

⇒ (60x-42y=0) × 10

⇒ 600x - 420y = 0                                         ............(3)

⇒ (-100x + 70y=0 ) × 6

⇒ -600x + 420 = 0

Solving equation 2 and 3 simultaneously

⇒ 600x - 420y = 0

⇒ -600x + 420 = 0

⇒ x = y = 0

Discriminant of the eqaution √2x²-5x+√2 is 17

The discriminant of a polynomial in mathematics is a number that relies on the coefficients and allows inference of some root features without computing them. It is basically a polynomial function of the original polynomial's coefficients.

To calculate the Discriminant of a quadratic equation which   is generally expressed as

ax² + bx + c = 0

The quadratic equation's discriminant, indicated by the letter D, is defined as

D = b² - 4ac

The minimum speed object must have at the top of the loop is 3.8m/s.

Friction is the force that resists the motion of an object, it works in the opposite direction of applied force. Centripetal force is the force applied to the center of the body moving in a circular motion, whereas gravitational force is the pull of gravity on a body i.e., it attracts a body toward the ground.

Diameter of loop= 3m

thus radius = 1.5m

Centripetal force =< gravitational attraction the object has.

Centripetal force ,F=mv^2/r ----1

where  M= mass v= velocity and r= radius

gravitational force is F=ma -----2

let 1=2

mv^2/r=ma

m is common so can be canceled out

a=v^2/r

An ordered pair is a set of two values, (x,y), where x and y are the coordinates. In an ordered pair, the first element is typically referred to as the x-coordinate, or the "first component" and it represents the horizontal position of the point on a coordinate plane. The second element is typically referred to as the y-coordinate, or the "second component" and it represents the vertical position of the point on a coordinate plane.

So, to find the first and second element of a pair, you can refer to the first element as the x-coordinate or the first component and the second element as the y-coordinate or the second component.

For example, in the ordered pair (4,3), the first element is 4, which represents the x-coordinate, and the second element is 3, which represents the y-coordinate.

The inequality d > 3 has infinitely many solutions because 4 and any number to the right of 3 on the number line can be substituted for d to make this inequality true.

Answer:

The volume of a balloon is directly proportional to the cube of its radius, so we can use the formula:

V1/V2 = (R1/R2)^3

Where V1 is the initial volume, V2 is the final volume, R1 is the initial radius, and R2 is the final radius. We know that when the radius is 4 inches, the volume is 192 cubic inches, so we can use this information to find the final volume when the radius is 3 inches.

V1 = 192 cubic inches

R1 = 4 inches

R2 = 3 inches

V1/V2 = (R1/R2)^3

V2 = V1 / (R1/R2)^3

V2 = 192 / (4/3)^3 = 192/ (4/27) = 192 * 27/4 = 192 * 6.75 = 1296 cubic inches

So, 1296 cubic inches of gas must be released to reduce the radius down to 3 inches.

It is typically used to refer to an amount of money, like when people discuss their income, but it can also be used to describe a quantity of something, such as the volume of water in a tank or the time required to complete a task.

We must divide the difference between Ezra and Haley's initial deposits by the difference between their weekly installments to figure out how many weeks it will take them to save the same amount of money. In this instance, their initial deposits differed by $804 ($862 - $58), while their weekly installments differed by $402 ($71 - $473). We can calculate that it will take them two weeks to save the same amount of money by dividing $804 by $402.

After two weeks, they will have $1,737 in savings. Haley will have $1,737 ($862 + $71 + $71 + $703) and Ezra will have $1,737 ($58 + $473 + $473 + $733) in their accounts after two weeks.

Answer 50 for the bottom and 48 for the sides

To graph the inequality 2y - 4x < 8, we can start by isolating the y variable on one side of the inequality. To do this, we add 4x to both sides:

An explanation graph is what?

A graph is a representation of the relationship between two variables that are normally measured along one of a pair of axes at right angles.

2y - 4x < 8

2y < 4x + 8

Next, we divide both sides by 2 to get y by itself:

y < 2x + 4

To graph this inequality, we can start by plotting the y-intercept, which is the point where x = 0. In this case, y = 2(0) + 4 = 4, so the y-intercept is (0, 4). Next, we can find the slope of the line, which is -2.

To graph the inequality -4y > -x + 12, we can start by isolating the y variable on one side of the inequality. To do this, we add x to both sides:

-4y > 12 - x

Next, we divide both sides by -4 to get y by itself:

y < -3 + (1/4)x

To graph this inequality, we can start by plotting the y-intercept, which is the point where x = 0. In this case, y = -3 + (1/4)(0) = -3, so the y-intercept is (0, -3). Next, we can find the slope of the line, which is (1/4).

The percentage and the z-scores for specific heights of the given normal distributions are as detailed below.

The first step is to draw the Normal curve with 8 regions, and then we now label the 7 vertical dividing lines with the mean plus/minus one/two/three standard deviations:

By adding the percentage values in the areas indicated in the question, we will arrive at;

The percentage of Ixxians that are;

i) Over 30 inches tall = 100% - (2.35% + 0.15%) = 97.5%

ii) Over 45 inches tall =  13.5% + 2.35% + 0.15% = 16%

iii) Under 50 inches tall = 100% - (2.35% + 0.15%) = 97.5%

iv) under 40 inches tall = 34% + 13.5% + 2.35% + 0.15% =  50%

v) between 35 and 55 inches tall = 34% + 34% +  13.5% + 2.35% = 83.85%

vi) between 25 and 35 inches tall = 13.5% + 2.35% 15.85%

The z-score is defined as the number of standard deviations above the mean corresponding to the given value. Thus;

i. For a height of 32 inches, the z-score is;

z = [32-40]/5

z = -1.6

ii. For a height of 47 inches, the z-score is;

z = [47 - 40]/5
