Answer:

12 and 5 inches since squaring them would equal 144+25, which is 169, and ✓169=13. the two legs have to equal the hypotenuse when combined to be a right triangle.

Answer:

12.5 Km / hour

Step-by-step explanation:

Average speed (s) is calculated as

s = [tex]\frac{distance}{time}[/tex]

distance covered is 50 Km and time taken is 4 hours, then

s = [tex]\frac{50}{4}[/tex] = 12.5 Km/ hour

Answer:

Square.

Step-by-step explanation:

a). Properties of a square → 1). All sides are equal in measure

                                        2). All interior angles are equal and measure 90°

                                        3). Diagonals are perpendicular and equal in

                                             measure.

Therefore, by third property, its a square because diagonals are perpendicular and  congruent.

Answer: CB = 7.    AC = 5.

Step-by-step explanation:

Well we know that A-B is 7. And this is a right triangle, so the CB will be the same length. So CB = 7.

Now AC.

You divide 45 degrees by 7. And you get five.

So AC = 5 and CB = 7.

Answer:

AC= 7√6/2

CB=7√2/2

Step-by-step explanation:

put 73.5 in √ it gives u 7√6/2

Answer:

(8, 0)

Step-by-step explanation:

TAKE NOTE: In a glide reflection, you always start w/ the second transformation.

RULE (in this case): (x, y) --> (y, x)

(2, 7) => (7, 2)

RULE: (x, y) --> (x + horizontal shift, y + vertical shift)

(7, 2) => (7+1, 2-2) or (8, 0)

You can check your answer by doing this the opposite way.

The time at which the temperature was -2.1°C is 5:05 PM

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The temperature is changing at a constant rate of = -0.75° C every half hour

So ,

30 min = -0.75° C

Divide by 3 on both sides , we get

10 min = -0.25°C

So , temperature is changing at a constant rate of = -0.25° C every 10 minutes

Now , the temperature at 6:45 PM = -4.6°C

So ,

The temperature at 6:15 PM = -4.6 + 0.75

                                               = -3.85°C

The temperature at 5:45 PM = -3.85 + 0.75

                                                = -3.1°C

The temperature at 5:15 PM = -3.1 + 0.75

                                               = -2.35°C

Now , for it to be -0.25°C , the time elapsed will be 10 minutes

So ,

The temperature at 5:05 PM = -2.35°C + 0.25°C

                                                = -2.1°C

Hence , the time at which the temperature was -2.1°C is 5:05 PM

My answer for dividing is 46.33333

Answer:

Step-by-step explanation:

There are 561 people.

When you divide by 12 you get 46 complete tables of 12

There are 9 people left over.

You can't round down. You must round up. These 9 people  get a table all to themselves.

So you need 47 tables.

Answer:

y=3x+2

-4x+4y=16

Four times a number : 4 × n = 4n

(let n represents the number)

Equals 14 : = 14

= 4 - 4n = 14

2. Each person paid : $42

Keith, Alyssa, and Sara : 3

The bill : let B represent bill

Answer:

92.75 cm²

Step-by-step explanation:

area of polygon = area of ∆EDA + area of ∆ADC +area of ∆ACB.

area of triangles is ½×base×height.

area of ∆EDA=½×EF×AD

=½×4.5×12

=27 cm². -------->(1)

area of ∆ADC=½×AD×DC

=½×12×5

=30 cm². --------->(2)

area of ∆ACB=½×AC×BG

=½×AC×5.5

from pythagorean theorem

(AC)²=(AD)²+(CD)²

= 25+144

= 169 cm then. AC= 13 cm

then area of ∆ACB=½×5.5×13

=35.75 cm² ---------->(3)

from equation (1), (2) and (3):

then the area of polygon = 27 + 30 + 35.75

=92.75 cm²

take x as the side of the cube.

surface area = 6a^2

= 6x^2

take 2x as the next cube

surface area = 6(2x)^2

= 6 x 4 x x^2

= 24x^2

cube two is 4 times more than cube 1 in surface area wise.
