Answer:

17.5 PROYECT AND SEVEN HOURS RATE OF

2.5 PROYECT PER HOUR

Answer:

17.5 projects in seven hours at a rate of 2.5 projects per hour.

Step-by-step explanation:

First, find the unit rate of projects per hour.

Next, find the number of projects Ms. Keller would grade in seven hours by multiplying the unit rate by seven hours.

Therefore, at this rate, Ms. Keller will grade 17.5 projects in seven hours at a rate of 2.5 projects per hour.

Answer:

Each corner of an octagon is 135

Use a protractor to help

NOTE: The sum of the interior angles of a regular octagon = (2n-4)*right angles or (n-2)*straight angles or (8–2)*180 =6*180 = 1080. So each interior angle of the regular octagon = 1080/8 = 135 deg.

Answer: 2970

Step-by-step explanation:

First, you do the first exponent in the first part which is 10^3 and the answer for that is 1000. Then you do 2.4x1000 which is 2400. Afterwards you do the second part's exponent which is 10^2 and you get 100 for that. Next, you do 5.7x100 which is 570. Finally you add 2400+570 and get 2970.

Answer:

Step-by-step explanation:

(2.4 x 10³) + (5.7 x 10²)

(2.4 x 1000) + (5.7 x 100)

2400 + 570

2970

Answer:

Neither triangle

Step-by-step explanation:

Define an irrational number that cannot be written as a fraction (denominator of 1 or 0 does are excluded).

Both triangles are good examples of common Pythagorean triples.

The Pythagorean theorem states that for any right triangle, the following is true:

[tex]a^2+b^2=c^2[/tex], where [tex]a[/tex] and [tex]b[/tex] are two legs of the triangle and [tex]c[/tex] is the hypotenuse.

Using this theorem we can solve for the hypotenuse of both triangles:

Triangle 1:

[tex]3^2+4^2=h^2,\\h^2=25,\\h=5\:\text{(rational)}[/tex]

Triangle 2:

[tex]0.5^2+1.2^2=h^2,\\h^2=1.69,\\h=1.3\:\text{(rational)}[/tex]

Answer:

53 minutes

Step-by-step explanation:

3:08-4:08 is exactly 1 hour

4:01-4:08 is 7 minutes difference

1 hour minus 7 minutes is 53 minutes

hope this helped! have a great day :)

The solution is : Ethan for 53 minutes baked the cake .

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

given that,

Ethan puts a cake in the oven to bake at 3:08 p.m. The cake is done at 4:01 p.m.

now, we have to find the time for the cake baked.

now, we get,

3:08-4:08 is exactly 1 hour

then, we have,

4:01-4:08 is 7 minutes difference

so, we get,

from 3.08pm to 4.01pm, the difference is:

1 hour minus 7 minutes is 53 minutes

Hence, The solution is : Ethan for 53 minutes baked the cake .

a) False

b) True

c) False

d) True

e) True

Step-by-step explanation:

Answer:

640cm³

Step-by-step explanation:

Length SF = ×2

Volume SF = ×2³ = ×8

Volume of B = 8 × 80 = 640cm³

The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.

Volume is a measurement of three-dimensional space that is utilized. It is frequently mathematically quantified using SI-derived units or different imperial or US traditional units. The concept of length is linked to the notion of capacity.

The diagram shows two similar solids, A and B. Solid A has a volume of 80 cm³.

The scale factor is given as,

Scale factor = 8 / 4

Scale factor = 2

The scale factor of the volume is given as,

⇒ 2³

⇒ 8

Then the volume of the solid B will be given as,

Volume of B = 8 x 80

Volume of B = 640 cm³

The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.

Answer:

slope = 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

20x - 2y = 9 ( subtract 20x from both sides )

- 2y = - 20x + 9 ( divide terms by - 2 )

y = 10x - [tex]\frac{9}{2}[/tex] ← in slope- intercept form

with slope m = 10

Answer: -4

Step-by-step explanation:

1. -4(m+6) = -8 (Simplify)

2. -4m -24 = -8 (Add 24 to -8)

3. -4m = 16 (Divide -4 by both sides to isolate m)

4. m = -4

Answer:

y-5=2.5(x-2)

Step-by-step explanation:

Since we know the slope, we know what x is. x is equal to 2.5. Therefore, the equation will be y=2.5x+?. The y-intercept on this graph is 0. This is because the only point on the y line is (0,0). Therefore, the y-intercept is 0. Therefore, the equation is y=2.5x.
