find the measure of BE step by step

Answers

Answer:

BE = 49 cm

Step-by-step explanation:

Use Pythagorean theorem

(hypotenuse)² = (base)² + (leg)²

ΔDEF,

DE² + EF² = FD²

DE² + 63² = 65²

DE² + 3969 = 4225

DE² = 4225 - 3969

DE² = 256

DE = √256 = √(16*16)

DE = 16 cm

ΔCBD,

BC² + BD² = CD²

56² +BD² = 65²

3136 + BD² = 4225

BD² = 4225 - 3136

BD² = 1089

BD = √1089 = √(33*33)

BD = 33 cm

BE = BD + DE

= 33 + 16

BE = 49 cm

The ordered pair (4, -5) satisfies the equation

3x- 2y= 22

What is 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. LHS = RHS is a common mathematical formula.

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:

We have ordered pair (4, -5)

First equation, 2x - 5 y= -30

So, 2(4)- 5(-5)= 8 + 25= 33

Second equation,7 x + 4 y = -19

So, 7(4)+4(-5)= 28 -20= 8

Third equation, 6x - y= -29

So, 6(4) +5= 24+ 5 = 29

Fourth equation, 8 x + 3 y= -37

So, 8(4) + 3(-5)= 32 - 15 = 17

Fifth equation, 3x- 2y= 22

3(4)- 2(-5)= 12 + 10 = 22

sixth equation, 2x+ 9y = -37

2(4) + 9(-5)= -37

seventh equation, 5x- 6y= 49

5(4) - 6(-5)= 20 + 30 = 50

eight equation, x+ 8y= -27

4+ 8(-5)= -36

someone helpppp pleaseeee

Answers

Answer:

138

Step-by-step explanation:

G + H = 180 {G, H are linear pair}

12x + 6 + 4x - 2 = 180

12x + 4x + 6 - 2 = 180

16x + 4 = 180

16x = 180 - 4

16x = 176

x = 176/16

x = 11

G = 12x + 6

= 12*11 + 6

= 132 + 6

= 138

This type of problem can be solved in various ways such as in terms of ratios and fractions, Let us go with fractions.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Miami Marlins won 14 of their first 27 games.

So, their win rate in decimal is,

= 14/27.

= 0.518.

∴ In 162 games at the same rate, Miami Marlins will win,

162×0.518.

= 84 games.

So, after playing 162 games they'll win 84games.

Answer:

0.36

Step-by-step explanation:

A= K/B^2

K= A × B^2

K= 1 × 3^2

K= 1×9

K= 9

Therefore if B is 5 then A can be calculated as follows.

K= A × B^2

9= A × 5^2

9= A × 25

9= 25A

A= 9/25

A= 0.36
