Cd is equal to this: first calculate AB by sin30 which is radical 3 then by sin45 you know bc is radical 3 too then by fisaghures ( idk what you call it)
calculate bd at the end you just gotta do this: bd-bc

The answer I got was 3-root 3. So a = 3 and b = -

crimeas [40]

Answer:

about 30

Step-by-step explanation:

Convert 74% to a decimal by dividing by 100 or by moving the decimal two places left.

74.% = 0.74

Multiply

0.74 x 40 = 29.6

Round to the nearest whole number

29.6 = 30

A school’s yearbook committee had many meetings last month the line plot summarizes how long each meeting lasted

kipiarov [429]

On the graph, it shows that the shortest meeting has lasted for 1/4 of an hour. An hour has 60 mins, you know it the shortest will be 15 minutes.

If its for any other number that you do not know, you can list as a proportion:

1/4 = x/60 (1 and x are on the top of the fractions)

Cross multiply: 1 * 60 = 60

Then divide by the number on the opposite corner of x: 60/4

x = 15

Factor completely 3ab − 5ax + 9b − 15x.

Alik [6]

Answer: The answers are given below.

Step-by-step explanation: We are given to factorise some quadratic expressions.

We will be using the following factorisation formula:

$x^2+ax+bx+ab=(x+a)(x+b).$

The factorisation is as follows:

We have

$(1)~3ab-5ax+9b-15x\\\\=a(3b-5x)+3(3b-5x)\\\\=(3b-5x)(a+3).$

Thus, option (B) $(3b-5x)(a+3)$ is correct.

$(2)~5x(x+3)+6(x+3)\\\\=(x+3)(5x+6).$

Thus, option (B) $(x+3)(5x+6)$ is correct.

$(3)~2cb+7cx+2b+7x\\\\=c(2b+7x)+1(2b+7x)\\\\=(2b+7x)(c+1).$

Thus, option (B) $(2b+7x)(c+1)$ is correct

$(4)~21x^3+35x^2+9x+15\\\\=7x^2(3x+5)+3(3x+5)\\\\=(3x+5)(7x^2+3).$

Thus, option (D) $(3x+5)(7x^2+3)$ is correct.

$(5)~9xy+36x-10y-40\\\\=9x(y+4)-10(y+4)=(y+4)(9x-10).$

Thus, option (C) $(y+4)(9x-10)$ is the correct option.

$(6)~14bx^2-7x^3-4b+2x\\\\=7x^2(2b-x)-2(2b-x)\\\\=(2b-x)(7x^2-2).$

Thus, option (B) $(2b-x)(7x^2-2)$ is the correct option.

$(7)~4xy+9x+24y+54\\\\=x(4y+9)+6(4y+9)\\\\=(4y+9)(x+6).$

Thus, option (D) $(4y+9)(x+6)$ is correct.

The ordered pair (8,5) represents a point on the graph of a proportional relationship. Which ordered pair also represents a poin

makkiz [27]

Given the ordered pair:

(8, 5)

Let's find the ordered pair that represents a point on the same graph assuming this is a graph of a proportional relationship.

Here, we have:

(x, y) ==> (8, 5)

Since this is a graph of a proportional relationship, let's find the constant of proportionality.

We have:

$K=\frac{y}{x}=\frac{5}{8}$

This means when x is 1, y is 5/8.

Thus, the ordered pair that also represents a point on the same graph is:

$(1,\frac{5}{8})$

ANSWER:

$\text{ B. (1, }\frac{5}{8})$
