Step-by-step explanation:

The greatest possible length of each  piece is 16 inches

Latisha has two pieces of ribbon. One piece of ribbon is 48 inches and  the other is 80 inches

Ribbon is to be cut into pieces of equal length

To find the greatest possible length of each piece, we have to find greatest common divisor of 48 and 80

The greatest common factor, or GCF, is the greatest factor that divides two numbers

Steps to find G.C.F of 48 and 80

1) Find the prime factorization of 48

[tex]48 = 2 \times 2 \times 2 \times 2 \times 3[/tex]

2) Find the prime factorization of 80

[tex]80 = 2 \times 2 \times 2 \times 2 \times 5[/tex]

3) To find the GCF, multiply all the prime factors common to both numbers:

Therefore, [tex]GCF = 2 \times 2 \times 2 \times 2 = 16[/tex]

So, 16 inches is the greatest possible length to cut so that every piece is of equal length.

Step-by-step explanation:

In military time format, first two digits are in hours. We know that, on a digital clock, the first two digits always shows between 01 to 24.

So, there is no probability that the first two digits will show more than 25.

As there is no probability, the probability will be zero or 0. Because probability of any incident is whether 0 or 1; where 1 is for certain event.

Answer:2

Step-by-step explanation:if she deposits 10 dollars every week she would be adding 10 dollars which means we have to multiply 10 by however many weeks she saves

Sarah's weekly deposits after h weeks can be calculated using the linear equation D = 200 + 10h. This equation includes her starting balance of $200 and adds $10 for each week.

The subject of this question is Mathematics, specifically focusing on the concept of linear equations.

The correct formula to show Sarah's deposits at the end of h weeks would be (3) D = 200 + 10h. This formula works by establishing 200 as her starting amount (her current bank balance), and adding $10 for each week (h).

For instance, if h was 5 weeks, Sarah would have D = 200 + 10 * 5 = 200 + 50 = $250 in her bank account. This demonstrates how the formula allows you to calculate her weekly deposits effectively.

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

step 1

Find the measure of angle BDA

we know that

Triangle ABD is an isosceles triangle

AB=AD ---> given problem

so

m∠ABD=m∠BDA

therefore

m∠BDA=72°

step 2

Find the measure of angle BAD

Remember that the sum of the interior angle in a triangle must be equal to 180 degrees

In the triangle BDA

m∠ABD+m∠BDA+m∠BAD=180°

substitute the given values

72°+72°+m∠BAD=180°

144°+m∠BAD=180°

m∠BAD=180°-144°=36°

step 3

Find the measure of angle BCA

In the triangle ABC

m∠BCA=m∠BAC

we have that

m∠BAC=m∠BAD=36°

therefore

m∠BCA=36°

step 4

Find the measure of angle ABC

In the triangle ABC

m∠BAC+m∠BCA+m∠ABC=180°

substitute the given values

36°+36°+m∠ABC=180°

72°+m∠ABC=180°

m∠ABC=180°-72°=108°

step 5

Find the measure of angle DBC

we know that

m∠DBC+m∠ABD=m∠ABC ----> by addition angle postulate

substitute the given values

m∠DBC+72°=108°

m∠DBC=108°-72°=36°

step 6

Find the measure of angle BDC

we know that

m∠BDC+m∠ADB=180° ----> by supplementary angles

substitute the given value

m∠BDC+72°=180°

m∠BDC=180°-72°=108°

step 7

In the triangle DBC we have

m∠DBC=36°

m∠BCD=m∠BCA=36°

so

The triangle BCD has two equal angles

therefore

Triangle BCD is an isosceles triangle

and

BD=BC

Answer:

The factory must produce 6,400 parts  so that there is 1 ton of scrap aluminum for recycling.

Step-by-step explanation:

1 part produced  ⇒ 5 ounces scrap aluminium recycled.

So, the ratio of parts produced : Scrap of aluminium = 1   : 5  .... (a)

Let us assume for m parts produced ,  1 ton of scrap is recycled.

Also, 1 ton = 2, 000 pounds

and 1 pound = 16 ounces

⇒ 1 ton = 2000 x (16 ounces)  = 32,000 ounces

So, for m parts made in the  factory, 32,000 ounces scrap is recycled.

So, the ratio of parts produced : Scrap of aluminium =  m   : 32,000  .... (b)

From both the given ratio, we get

1   : 5  = m   : 32,000

or, [tex]\frac{1}{5}  = \frac{m}{32,000}  \implies m = \frac{32,000}{5}  = 6,400[/tex]

⇒ m = 6,400

Hence, the factory must produce 6,400 parts  so that there is 1 ton of scrap aluminum for recycling.

Answer:

z = 14

Step-by-step explanation:

Solve for z:

(4 z)/7 - 15 = -7

Put each term in (4 z)/7 - 15 over the common denominator 7: (4 z)/7 - 15 = (4 z)/7 - 105/7:

(4 z)/7 - 105/7 = -7

(4 z)/7 - 105/7 = (4 z - 105)/7:

1/7 (4 z - 105) = -7

Multiply both sides of (4 z - 105)/7 = -7 by 7:

(7 (4 z - 105))/7 = -7×7

(7 (4 z - 105))/7 = 7/7×(4 z - 105) = 4 z - 105:

4 z - 105 = -7×7

7 (-7) = -49:

4 z - 105 = -49

Add 105 to both sides:

4 z + (105 - 105) = 105 - 49

105 - 105 = 0:

4 z = 105 - 49

105 - 49 = 56:

4 z = 56

Divide both sides of 4 z = 56 by 4:

(4 z)/4 = 56/4

4/4 = 1:

z = 56/4

The gcd of 56 and 4 is 4, so 56/4 = (4×14)/(4×1) = 4/4×14 = 14:

Answer:  z = 14

Answer:

v(x) = x(22 - 2x)(28 - 2x)

Step-by-step explanation:

The length of the box = 28 - 2x inches,

The width = 22 - 2x inches and the height  = x inches.

v(x) = x * width * length.

The volume of the open top box is [tex]V(x) = (28 - 2x)(22 - 2x)(x)[/tex] cubic inches

The volume of the box is V = (length)(width)(height).

Let the cutout side length be [tex]x[/tex] inch,

We are to cut out [tex]x[/tex] by

So, the length of the box is [tex]28 - 2x[/tex] inch

the width of the box is [tex]22 - 2x[/tex] inch and

the height of the box is [tex]x[/tex] inch

Now, substituting the values in the volume formula, we get

[tex]V(x) = (28 - 2x)(22 - 2x)(x)[/tex] cubic inches

Answer:

The number is -9.

Step-by-step explanation:

I set it up like this:

(-8) - 3x = 19

Then you add 8 to both sides of the equation in order to get rid of the negative 8.

(-8) + 8 - 3x = 19 + 8

After solving you would end up with this:

- 3x = 27

Then, you need to get the x by itself, so you divide by -3. In order to keep the equation equal though, you need to also divide the right side of the equation by -3.

- 3x ÷ -3 = 27 ÷ -3

Your final answer after solving would be:

x = -9

Answer:

The answer is b = 1/24.

Step-by-step explanation:

Given:

25+11/12b=47.

Now, to solve the equation to get the value of b:

[tex]25+\frac{11}{12b}=47[/tex]

Subtracting both sides with 25 we get:

[tex]\frac{11}{12b}=22[/tex]

Multiplying both sides by 12b we get:

Answer:

(a) y = -2 x -2

(b)  y = -2 x + 1

(c)  y = -2 x + 3

Step-by-step explanation:

The given lines r , s and t are parallel.

⇒ Slope of line r = Slope of line s = Slope of line t = (-2)

The point slope equation for any line is given as

y = m x + C : m = slope pf line, C is y - intercept.

Y intercept is a point on line when x = 0.

Now for the line r, slope = (-2) and y intercept = (-2)

So, the equation is given as y = -2x -2

Now for the line s, slope = (-2) and y intercept = (1)

So, the equation is given as y = -2 x + 1

Now for the line t, slope = (-2) and y intercept = (3)

So, the equation is given as y = -2 x + 3
