Iterations question 12 :) just need some help

Answer:you need common denominatord 4*2=8 3*2=6 6/8+1/8=7/8 of sugar

Step-by-step explanation:

Final answer:

To find w from the equation 3w - 4z = 8, add 4z to both sides, and then divide by 3 to isolate w, giving w = (4z + 8) / 3.

Explanation:

The equation 3w - 4z = 8 is a linear equation in two variables (w and z). To find w in terms of z, you need to isolate w on one side of the equation. Here is the process step by step:

Add 4z to both sides of the equation: 3w - 4z + 4z = 8 + 4z.

Simplify the equation: 3w = 4z + 8.

Divide every term by 3 to solve for w: w = (4z + 8) / 3.

So, w is equal to (4z + 8) / 3 when isolated from the given equation.

Step-by-step explanation:

Area of a circle = PI x r^2

r is 1/2 the diameter = 0.5 inches

Area = 3.14 x 0.5^2

Area = 0.79 in^2

It looks like it’s missing something...is it a part A ?

12 in. ²

a = bh

a = 2 x 6

a = 12 in. ²

Answer:

12 in. ^2

Step-by-step explanation:

The area of a rectangle can be found by using the formula legnth x width.

Here the legnth is 2 in. and the width is 6 in.

6 x 2 = 12

Whenever you find the area, unit of measurement is ^2, thus resulting in the answer 12 in. ^2

Answer:

8 minutes if Jane was assumed to be stationary

Step-by-step explanation:

The question is on relative speed

First find the distance covered by Jane when Sally left school

Speed=Distance/Time ⇒⇒ Distance=Time×Speed

Time=10minute=10/60 hrs

Jane's speed= 12mph

Distance covered by Jane when Sally left school was= 12 ×10/60 = 2miles

So, when Sally left school, Jane was 2 miles away. To find the time Sally requires to catch up with Jane;

Time=Distance/speed

Time of meeting =2/15 hrs ⇒⇒ 2/15 × 60 =8minutes

Answer:

- 7, 28, - 112, 448

Step-by-step explanation:

To obtain the next term in a geometric sequence multiply the previous term by r

Given

a₁ = - 7 and r = - 4, then

a₂ = - 7 × - 4 = 28

a₃ = 28 × - 4 = - 112

a₄ = - 112 × - 4 = 448

The first four terms are - 7, 28, - 112, 448

The answer is C. C is not a proportion.

Hope this helps!

Answer:

C

Step-by-step explanation:

By definition a proportion should be equal to each other and can be multiplied by the same number on the numerator and the denominator to make the second fraction.

[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]

[tex]\frac{x_1}{y_1}*\frac{z}{z}=\frac{x_2}{y_2}[/tex]

A

[tex]\frac{3}{7}*\frac{3}{3}=\frac{9}{21}[/tex]

So it is a proportion.

B

[tex]\frac{24}{56}/\frac{8}{8}=\frac{3}{7}[/tex]

So it is a proportion.

C

[tex]\frac{3}{7}*\frac{3}{4}=\frac{9}{28}[/tex]

So it is not a proportion.

D

[tex]\frac{3}{7}*\frac{4}{4}=\frac{12}{28}[/tex]

Answer:

128

Step-by-step explanation:

Method A.

The volume of the prism is 2 cubic units.

Each cube has side length of 1/4 unit.

The volume of each cube is (1/4)^3 cubic unit.

The volume of each cube is 1/64 cubic unit.

To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.

(2 cubic units)/(1/64 cubic units) =

= 2/(1/64)

= 2 * 64

= 128

Method B.

Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128

He right answer is 128

ANSWER

B. The two middle coefficients add to the correct number but do not multiply to the correct number.

EXPLANATION

The given quadratic trinomial that Tina tries to factor is

[tex]10 {x}^{2} - 13x - 3[/tex]

Comparing to

[tex]a{x}^{2} + bx + c[/tex]

we have a=10, b=-13 and c=-3

ac=-3×10=-30

We split the middle term so that their sum is -13.

Tina use

-10,-3

to get

-10x-3x

The sum is -13x alright but the product is not -30.

B is correct.

What is segment ab? is there a picture that is supposed to go with it?

Answer:  The required co-ordinates of point M are (8, 9).

Step-by-step explanation:  Given that the point M divides segment AB into a ratio of 2 : 3, where A is at (0, 15) and B is at (20, 0).

We are to find the co-ordinates of point M.

We know that

the co-ordinates of a point that divides the line segment joining the points (a, b) and (c, d) are given by

[tex]\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).[/tex]

For the given division, (a, b) = (0, 15), (c, d) = (20, 0) and m : n = 2 : 3.

Therefore, the co-ordinates of point M are given by

[tex]\left(\dfrac{2\times20+3\times0}{2+3},\dfrac{2\times0+3\times15}{2+3}\right)\\\\\\=\left(\dfrac{40}{5},\dfrac{45}{5}\right)\\\\\\=\left(8,9).[/tex]

Thus, the required co-ordinates of point M are (8, 9).

Answer:

y = -2x + 16

Step-by-step explanation:

A line perpendicular to y = (1/2)x - 6 would have a slope that is the negative reciprocal of 1/2, that is, a slope of -2.  Here the given point is (h, k):  (6, 4)

Applying the point-slope formula of the straight line,

y - k = m(x - h), where (h, k) is the point, we get:

y - 4 = -2(x - 6), or

y       = 4 - 2x + 12, or      

y   = -2x + 16

[tex]\large\boxed{Q6.\ \sin X\approx0.778}\\\boxed{Q7.\ x\approx5.9}[/tex]

Step-by-step explanation:

Q6.

[tex]\sin\theta=\dfrac{opposite}{hypotenuse}[/tex]

We have

[tex]opposite=14\\\\hypotenuse=18[/tex]

Substitute:

[tex]\sin X=\dfrac{14}{18}=\dfrac{14:2}{18:2}=\dfrac{7}{9}=0.777...\approx0.778[/tex]

Q7.

Use sine.

We have

[tex]opposite=x\\\\hypotenuse=8\\\\\alpha=48^o\\\\\sin48^o\approx0.7431[/tex]

Substitute:

[tex]\dfrac{x}{8}=0.7431[/tex]               multiply both sides by 8

[tex]x=5.9448\to x\approx5.9[/tex]

For this case we must write in algebraic symbology the expression described above:

We have an equation, then:

We construct the equation:

Answer:

11+x

Step-by-step explanation:

Straight outta Khan

The width of the rectangle with an area of 121-x^2 square meters and a length of 11 - x meters is represented by the expression 11 + x meters.

The area of a rectangle is the product of its length and width. In this case, the area is given as 121-x^2 square meters, while the length is given as 11 - x meters. To find the expression for the width, we divide the area by the length. Therefore, the width w can be represented by the following equation:

w = \(\frac{Area}{Length}\) = \(\frac{121-x^2}{11-x}\).

Due to the structure of the quadratic area (a perfect square difference) and the linear length (a factor of the quadratic), the equation simplifies to:

w = \(\frac{(11+x)(11-x)}{11-x}\).

Canceling out the common factor (11-x), we are left with:

w = 11 + x.

Thus, the expression representing the width of the rectangle is 11 + x meters.

Answer: [tex]\frac{2a\sqrt{c}}{3}[/tex]

Step-by-step explanation:

Remember that:

Given the expression [tex]\frac{6(\sqrt{a^3b^2c^4})}{9b\sqrt{ac^3} }[/tex]

You know that:

[tex]a^3=a^2*a\\c^3=c^2*c[/tex]

Then, you must rewrite the expression and simplify:

[tex]\frac{6\sqrt{a^2ab^2c^4}}{9b\sqrt{ac^2c} }=\frac{6abc^2\sqrt{a}}{9bc\sqrt{ac}}=\frac{2ac\sqrt{a}}{3(\sqrt{a})(\sqrt{c})}=\frac{2ac}{3\sqrt{c}}[/tex]

Multiply the numerator and the denominator by [tex]\sqrt{c}[/tex]:

[tex]\frac{(2ac)\sqrt{c})}{(3\sqrt{c})(\sqrt{c})}=\frac{2ac\sqrt{c}}{3(\sqrt{c})^2}=\frac{2ac\sqrt{c}}{3c}=\frac{2a\sqrt{c}}{3}[/tex]

Answer:

0.5r

Step-by-step explanation:

If Jerry took half the time Macy did then that means Macy took twice as long as Jerry. If Jerry’s speed was r then Macy’s speed is 0.5r or half the speed of Jerry. This will mean Macy goes half as slow and takes twice as long to get there.

The average speed of Marcy in miles per hour is 0.5r.

If Jerry took half the time Marcy did then that means Marcy took twice as long as Jerry. If Jerry’s speed was r then Macy’s speed is 0.5r or half the speed of Jerry. This will mean Marcy goes half as slow and takes twice as long to get there.

Hence, The average speed of Marcy in miles per hour is 0.5r.
