Rachel had a total of 854 local and foreign stamps. 3/7 of the stamps were foreign stamps. After her father gave her more foreign stamps, the fraction of the stamps that were foreign stamps became 2/3. How many foreign stamps did Rachel’s father give her?

Answers

Answer:

27 other stamps

Step-by-step explanation:

if you take the 88 percent and turn it into a decimal you get .88 Than you multiply .88 times the 225 stamps and that gives you 198 stamps. But that is not the answer because that is the number for foreign stamps and its asking how many other stamps are there. so you would do 225-198 stamps and get the left over 27 stamps!

27 other stamps

A cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm, what was its radius (in mm) before deformation

Answers

The radius of the  copper specimen before deformation was 8 mm of a cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm

Given information:

Ductility (%el) of cold-worked copper = 25%Cold-worked radius = 10 mm

To find the radius of the copper specimen before deformation, we'll use the formula for calculating the ductility:

Ductility (%el) = ((Final radius - Initial radius) / Initial radius) * 100

Let's denote the initial radius as "r" (in mm). The final radius is 10 mm (after cold-working).

25% = ((10 - r) / r) * 100

Now, solve for "r":

25% = (10 - r) / r

Convert percentage into fraction:

25/100 = (10 - r) / r

Convert fraction into decimal:

0.25 = 10 - r/r

on Cross-multiplication gives:

 0.25r = 10 - r

Add r on both sides gives,

1.25r = 10

On dividing by 1.25 gives:

r = 8 mm

So, the radius of the copper specimen before deformation was 9.75 mm.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle
and two congruent triangles. As a result, the altitude cuts the base into two equal
segments. The length of the altitude is 18 inches, and the length of the base is
17
inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.

Answers

Answer:56.8 inches

Step-by-step explanation:

For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.

the triangle is cut directly in half so both halves of the base are 17/2

17/2 = 8.5

solve through pythagoren theorum

altitude^2 + (half of base)^2 = (diagonal length)^2

18^2 + (8.5)^2 = (diagonal length)^2

324 + 72.25 = (diagonal length)^2

396.3 = (diagonal length)^2

[tex]\sqrt{396.3}[/tex] = diagonal length

diagonal length = 19.9

diagonal length + diagonal length + base = perimeter

19.9 + 19.9 + 17 = perimeter

56.8 inches = perimeter

The function P(x)=2x+1 is dilated by the function I(x)=1/2P(x). Which function rule represents I(x)?

Answers

We will see that we can write the function I(x) as:

I(x) = x + 1/2.

How to get the function I(x)?

We know that I(x) is a vertical dilation of scale factor 1/2 of P(x), where:

P(x) = 2x + 1.

The vertical dilation will be written as:

I(x) = (1/2)*P(x).

If we replace P(x) by the actual function, we will get:

I(x) = (1/2)*(2x + 1) = x + 1/2.

Then we can conclude that the function I(x) is:

I(x) = x + 1/2.

For what values of "x" is the inequality 3(x+2)-x<8 true?

x > 1
x < 1
x < 7
x > 7

Answers

Given ↓The inequality 3(x+2)-x<8

To Find ↓Which values of x  make the inequality true

Calculations ↓

We can't determine right off the bat what values of x make this inequality true, so we should solve it first.

First, use the distributive property and distribute 3 :

3(x+2)-x<8

3x+6-x<8

Now subtract 6 on both sides :

3x-x<8-6

3x-x<2

now , subtract the x's :

2x<2

Divide by 2 on both sides :

x<1

So the values of x less than 1 make this inequality true.

Let's try -1 (-1 is less than 1)

Plug it in ↓

3(-1+2)-(-1)<8

3(1)+1<8

3+1<8

4<8

4 is less than 8.

Therefore, the values of x that make this inequality true are indeed less than 1.

Answer:

x < 1

Step-by-step explanation:

Expand the brackets: 3 * x = 3x and 3 * 2 = 6

Current inequality: 3x + 6 - x < 8

Collect like x terms: 3x - x = 2x

Current inequality: 2x + 6 < 8

Collect like integer terms: subract 6 from both sides

Current inequality: 2x < 2

Convert 2x to x: divide both sides by 2

Final answer = x < 1

8. A cube container, with original volume 64 in. 3, is being redesigned to increase

its capacity. The expression x + 64 in. ? models the volume of the new cube.

If the volume can increase by a maximum of 100 in. 3, what is the maximum

measurement of the edge of the larger cube, rounded to the nearest tenth?

Answers

The volume of the cube container is the amount of space in it, and the maximum measurement of the edge of the larger cube is 5.5 inches

How to determine the maximum edge of the larger cube?

The volume of the container is given as:

V = 64 cubic inches

When it increases by a maximum of 100 cubic inches, the new volume becomes

V = 164 cubic inches

The volume of a cube container is calculated using:

V = l³

Where l represents the edge length of the cube

Substitute 164 for V

l³ = 164

Take the cube root of both sides

l = 5.5

Hence, the maximum measurement of the edge of the larger cube is 5.5 inches
