Answer:

There are 6 blocks in each row

Step-by-step explanation:

The total number of blocks is 42 and the number of rows is 7. So the equation would be 42 ÷ 7.

So, 42 ÷ 7 = 6. There are 6 blocks in each row.

Hope this Helps!

Total number of row is 6 row.

Given that;

Total number of block = 42 block

Total number i=of block in each row = 7

Find:

Total number of row

Computation:

Total number of row = Total number of block / Total number i=of block in each row

Total number of row = 42 / 7

Total number of row = 6

Grandpa's age=80y/o

Step-by-step explanation:

let Abdul's age be 'x'

so, grandpa's age=4x

Grandpa's age 10 yrs ago= 4x-10

according to the question, grandpa's age 1o yrs ago=7(x-10)

so, 4x-10=7(x-10)

Step-by-step explanation:

First find out how many beads cover 1 inch of the string which is 4 beads then multiply that number, 4, by the length of the string, 13. You should get 52.

Answer: 52

Part A

Why?

So for this question. You can write a ratio what will the balance be what information do they give you that you can register as a ratio? Well, what will the ratio be?

OK, THE WORK IS HERE!--v

So 12 beads are the ratio.

Now what do we want to know? Well, we want to know how to solve it.

1. 12b= __

3in= 13in <---------well-known way people use it to solve

--------------------------------------------------------------------------------------------------------------------------------

2. 12b divided by 12 = 1b

3in divided by 12= ____->ANSWER: 0.25 <----- Not that many people do it this way

for 2. solve-v

Answer: Number of children  = 168

Number of adults = 120

Step-by-step explanation:

Let x = Number of children and y = Number of adults

As per given,

x+y=288          (i)

2.25x+6.80y =1194       (ii)

Multiply 2.25 on both sides in (i)

2.25x+2.25y= 648       (iii)

Eliminate (iii) from (ii)

4.55y=546

[tex]\Rightarrow y=\dfrac{546}{4.55}\\\\\Rightarrow\ y=120[/tex]

Put y= 120 in (i)

x+120=288

⇒ x=288-120

⇒ x= 168

Hence, Number of children  = 168

Number of adults = 120

Answer:

y= -1/2x

Step-by-step explanation:

The statement that describes the graph of the system of equations is:

C. The lines intersect at (1.6, 1.4).

Here, we have,

To determine the description of the graph of the system of equations:

1.5x + 0.2y = 2.68

1.6x + 0.3y = 2.98

We can start by comparing the slopes of the two lines.

The equations are in the form y = mx + b, where m represents the slope.

In the first equation, the slope is 0.2, and in the second equation, the slope is 0.3.

Since the slopes are different, we can conclude that the lines are not parallel (option A) or overlapping at all points (option B).

To determine the point of intersection, we can solve the system of equations.

By using any appropriate method, we find that the lines intersect at (1.6, 1.4) (option C).

Therefore, the statement that describes the graph of the system of equations is:

C. The lines intersect at (1.6, 1.4).

Answer:

The Cheetah's initial speed is 19.4 miles per hour

Step-by-step explanation:

Since the Cheetah is initially running and then gradually increases its speed by 50.6 miles per hour to reach a top speed of 70 miles per hour, let the Cheetah's initial speed be u.

Also, let the increase in the Cheetah's speed be Δu and let v be the Cheetah's final speed.

Now, the final speed, v = initial speed, u + change in speed, Δu

So, v = u + Δu

So, the Cheetah's initial speed is u = v - Δu

Now, v = 70 mi/h and Δu = 50.6 mi/h

Substituting v and Δu into the equation, we have

u = v - Δu

u = 70 mi/h - 50.6 mi/h

u = 19.4 mi/h

So, the Cheetah's initial speed is 19.4 miles per hour

Answer:

Step-by-step explanation:

Step one:

given

A= 260ft^2

W= 2x + 4

B=8x + 2

Step two:

A=L*W

260=(2x+4)*(8x + 2)

open bracket

260=16x^24x+32x+8

16x^2+56x-252=0

Solving using quadratic formula

the roots are

x=-6.0

x= 2.6

Hence the value of x= 2.6ft

Answer:

Here you go sorry.

Step-by-step explanation:

Question 1.

y = 4x - 8 has a slope of 4. Since parallel lines have equal slopes, the slope of your new line will also be 4.

Now, you have a point (3,9) and a slope 4. Use the Point-Slope Form for the equation of a line.

y - y1 = m(x - x1)

y - 9 = 4(x - 3)

y - 9 = 4x - 12

y = 4x - 3

Question 2.

Since it is parallel, it must have the same slope.

y = (1/2)x + b

Find b from the given point.

4 = (1/2)(2) + b

b = 3

y = (1/2)x + 3

Answer:

The water level is rising at the rate 0.238 cm per second

Step-by-step explanation:

Let the radius and height of water at time t be r and h respectively.

Height of cup =H= 8 cm

Radius of cup = R = 4 cm

By symmetry

[tex]\frac{r}{h}=\frac{4}{8} \\r=\frac{1}{2}h ---1[/tex]

Volume of water at time t , [tex]V= \frac{1}{3} \pi r^2 h[/tex]

[tex]\frac{dV}{dt}=\frac{1}{3}\pi 2r \frac{dr}{dt} h+\frac{1}{3} \pi r^2 \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{3}\pi r (2 \frac{dr}{dt} h+ r \frac{dh}{dt})[/tex]

With 1

[tex]\frac{dr}{dt}=\frac{1}{2} \frac{dh}{dt}[/tex]

So,

[tex]\frac{dV}{dt}=\frac{1}{3}\pi (\frac{1}{2}h) (2 (\frac{1}{2} \frac{dh}{dt}h)+ r \frac{dh}{dt})\\\frac{dV}{dt}=\frac{1}{3}\pi (\frac{1}{2}h) ( \frac{dh}{dt}h+ r \frac{dh}{dt})\\\frac{dV}{dt}=\frac{1}{3}\pi (\frac{1}{2}h) ( h+\frac{1}{2}h) \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{6}\pi h(\frac{3h}{2}) \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{6}\pi (\frac{3h^2}{2}) \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{12}\pi 3h^2 \frac{dh}{dt}[/tex]

We are given that Water is poured into a conical paper cup at the rate of 3 cubic centimeters  (cm) per second (s).

We are supposed to find how fast the water level is rising at the instant the water is 4 cm deep.

So,[tex]\frac{1}{12}\pi 3(4)^2 \frac{dh}{dt}=3\\\frac{dh}{dt}=\frac{3 \times 12}{\pi 3(4)^2 }=0.238[/tex]

Hence the water level is rising at the rate 0.238 cm per second

The radius in terms of height is [tex]\mathbf{r =\frac 12h}[/tex], while the water level increases at 0.239 cm per second when the height is 4 cm

(a) Radius in terms of height

The given parameters are:

[tex]\mathbf{h = 8cm}[/tex] --- height

[tex]\mathbf{r = 4cm}[/tex] --- radius

The above parameters can be written as:

[tex]\mathbf{r :h =4cm : 8cm}[/tex]

[tex]\mathbf{r :h =4 : 8}[/tex]

Express as fractions

[tex]\mathbf{\frac rh =\frac 48}[/tex]

[tex]\mathbf{\frac rh =\frac 12}[/tex]

Multiply both sides by h

[tex]\mathbf{r =\frac 12h}[/tex]

(b) How fast the water is rising

The volume of a cone is:

[tex]\mathbf{V = \frac 13 \pi r^2h}[/tex]

Differentiate with respect to time

[tex]\mathbf{V' = \frac 13 \pi(2rh\ \frac{dr}{dt} + r^2\frac{dh}{dt})}[/tex]

When the water is 4cm deep, then the radius is 2cm using [tex]\mathbf{r =\frac 12h}[/tex]

So, we have:

[tex]\mathbf{V' = \frac 13 \pi(2 \times 2 \times 4\times \frac{dr}{dt} + 2^2\frac{dh}{dt})}[/tex]

[tex]\mathbf{V' = \frac 13 \pi(16 \frac{dr}{dt} + 4\frac{dh}{dt})}[/tex]

Also, we have:

[tex]\mathbf{r =\frac 12h}[/tex]

Differentiate with respect to time

[tex]\mathbf{\frac{dr}{dt} = \frac{1}{2}\frac{dh}{dt}}[/tex]

So, we have:

[tex]\mathbf{V' = \frac 13 \pi(16 \times \frac{1}{2}\frac{dh}{dt} + 4\frac{dh}{dt})}[/tex]

[tex]\mathbf{V' = \frac 13 \pi(8\frac{dh}{dt} + 4\frac{dh}{dt})}[/tex]

[tex]\mathbf{V' = \frac 13 \pi(12\frac{dh}{dt})}[/tex]

Expand

[tex]\mathbf{V' = 4\pi\frac{dh}{dt}}[/tex]

The volume increases at 3 cm^3 per second.

So, we have:

[tex]\mathbf{3 = 4\pi\frac{dh}{dt}}[/tex]

Divide both sides by 4

[tex]\mathbf{0.75 = \pi\frac{dh}{dt}}[/tex]

Divide both sides by pi

[tex]\mathbf{0.239 = \frac{dh}{dt}}[/tex]

Rewrite as:

[tex]\mathbf{\frac{dh}{dt} = 0.239}[/tex]

Hence, the water level increases at 0.239 cm per second when the height is 4 cm
