Expand this expression by using the distributive property. 4( -2g + 4 -3t)

1/8 + 1/4

the least common multiple of 8 and 4 is 8. Convert 1/8 and 1/4 to fractions with denominator 8.

1/8 + 2/8

Because 1/8 and 2/8 have the same denominator, add them by adding their numerators.

1+2/8

add 1 and 2 to get 3

3/8 or 0.375

Answer:

For each part, find how many numbers have the stated characteristic, then divide by 21.

e.g. multiples of 5:

these would be 10, 15, 20, 25, and 30

so prob (a multiple of 5 ) = 5/21

14 cups of water/35 cups of broth

This is the same as 14 divided by 35

14 divided by 35 is 0.4

Answer:

True is the most reasonable than False.

Step-by-step explanation:

If we go by "logic", we know that radius and anything that tells you how long, how far, how tall, etc; the value must always be positive.

The area of circle is expressed as:

[tex] \displaystyle \large{A = \pi {r}^{2} }[/tex]

Where r = radius

Since we know that radius cannot be negative going with logic and real basic geometry, the only radius that satisfies A = 9π is r = 3.

[tex] \displaystyle \large{A = \pi {3}^{2} } \\ \displaystyle \large{A = 9\pi }[/tex]

Now if we do not go by logic of real basic geometry, such as length being negative and all.

Since A = 9π, substitute A = 9π in.

[tex] \displaystyle \large{9\pi = \pi {r}^{2} }[/tex]

Divide both sides by π.

[tex] \displaystyle \large{ \frac{9\pi}{\pi} = \frac{\pi {r}^{2} }{\pi} } \\ \displaystyle \large{ 9 = {r}^{2} }[/tex]

Square both sides, adding plus-minus, apply QE.

[tex] \displaystyle \large{ \pm \sqrt{9} = \sqrt{ {r}^{2} } } \\ \displaystyle \large{ \pm 3 = r}[/tex]

So r = ±3 or radius = +3 and -3

So r can be both 3 or -3 if we do not follow logic itself.

However, the answer should be true instead of false as radius being only positive sounds more logical and reasonable rather than radius being negative.

Step-by-step explanation:

given :

A=5x - 10

B = 3x

C= 2x - 10

solution:

A+B+C = 180°

5x - 10 + 3x+ 2x - 10 = 180

10x -20 = 180

10x = 200

x = 20

A = 5(20)-10 = 100-10 = 90°

B = 3x = 3(20) = 60°

C = 2x-10 =2(20)-10 =40-10 = 30°

Find the value of x:

The length of the building on the scale drawing for the given context is obtained as: 16 cm.

For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.

Then it means

[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

For the given case, The height of the building 125 meters was drawn as 25 cm in the scale drawing.

That means:

[tex]\rm 125 \: m : 25 \: cm\\\\1 \: m : \dfrac{25}{125} \: cm\\\\1 \: m :\dfrac{1}{5} \: \rm cm[/tex]

Since the length of the building in reality is 80 meters.

Thus, in scale drawing, it would become:

[tex]\rm 80 \: m = 80 \times 1 \: m : 80 \times \dfrac{1}{5} \: cm = 16 \: \rm cm[/tex]

Thus, The length of the building on the scale drawing for the given context is obtained as being of 16 cm.

(2 + x)(3 - x)

To factorise a quadratic we first need to think of factors of the number term (The 6).

Factors of 6 are 1 & 6 and 2 & 3.

What combination of addition or subtraction of these factor pairs will produce the second number (which is positive 1x)

3 minus 2 will give us 1, so we will use this pair

Throw up your brackets with the x's and the number pair we chose

(x  2) (x  3)

We chose 3 minus 2

So in our brackets we will put positive 3, negative 2

(x - 2) (x + 3)

Step-by-step explanation:

The diagonal is the hypotenuse of the triangle with sides of 20.8 cm and 30.6 cm.

Find the length of the diagonal using Pythagorean:

Convert the length to inches:

Answer:

37 cm = 14.57 in

Step-by-step explanation:

A rectangle is a 4-sided shape with 2 pairs of congruent, parallel sides (width and length).

All interior angles of a rectangle are 90°.

The diagonal of a rectangle forms 2 congruent right triangles.  

Given:

Pythagoras Theorem

  [tex]a^2+b^2=c^2[/tex]

where:

Therefore:

Substitute the given values into the formula and solve for c:

[tex]\implies 20.8^2+30.6^=c^2[/tex]

[tex]\implies c^2=1369[/tex]

[tex]\implies c=\sqrt{1369}[/tex]

[tex]\implies c=37\:\:\sf cm[/tex]

Therefore, the length of the diagonal of the rectangle is 37 cm.

Conversion

1 inch ≈ 2.54 cm

To convert the measure of the diagonal to inches, divide 37 cm by 2.54:

[tex]\implies \dfrac{37}{2.54}=14.57 \sf \:in\:\:(2 \: d.p.)[/tex]

Answer:

The value of y is directly proportional to the value of x. When x = 4.25, the value of y is 2. What is the value of x when y = 8?

Step-by-step explanation:

Answer:

x = 17 when y = 8

Step-by-step explanation:

Considering the value of y,

→ 8 ÷ 2

→ 8/2 = 4

Now the value of x will be,

→ x = 4.25 × 4

→ [ x = 17 ]

Hence, the value of x is 17.
