I’m looking for x can someone help me

Answers

Answer 1

Answer:

x = 30°

Step-by-step explanation:

Since m and n are perpendicular, then

y + 70° = 90° ( subtract 70° from both sides )

y = 20°

thus 40 + y = 40° + 20° = 60°

Then

x + 60° = 90° ( subtract 60° from both sides )

x = 30°

at a school
number of boys:number of girls= 11:9
There are 124 more boys than girls.
Work out the total number of students at the school

Answers

Answer:

Total students = 1240

Step-by-step explanation:

Boys : girls = 11 : 9

Number of boys = 11x

Number of girls = 9x

11x - 9x = 124

2x = 124

x = 124/2

x = 62

Number of boys = 11x = 11 *62 = 682

Number of girls = 9x = 9*62 = 558

Total students = 682 + 558 = 1240

Answers

Answer: 74.6

we draw a right triangle ABC, have: ∠ABC = 90°, AB = 20 and ∠BAC = 75°, the height of the building is BC

we also have: tan 75° = BC/AB = BC/20

=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6

the lenght of the floor is 32 m longer than its width and there is greater than 200 square meters. you will cover the floor completely with tiles. what will be the possible dimension of the floor?

Answers

Let’s assume the width of the floor is x and the area is a

To figure out the dimensions we need to figure out the value of the variable (x)

This means that the length is xm+32m (the m is for metres) and that the area is a>200m2

Because it says what is the possible dimensions let make the area 201m2

The formula for the area of a rectangle is length times width so the equation we use to figure out the value of x

201=x+x+32

So let’s collect like terms and solve from there
201=2x+32
201-32=2x+32-32
169=2x
169/2=2x/2
84.5=x

Now that we know the value of x is 84.5 we can figure out the length is 116.5m and the width is 84.5m

Therefore the dimensions of the floor is 116.5m by 84.5m

The length of a rectangle is 6 centimeters less than the width. The perimeter is 206 centimeters. Find the width and the length.

What is the slope of a line that passes through the points (2,0) and (6,−12)

Answers

Answer:

slope = -3

Step-by-step explanation:

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (2, 0), (6, -12)

(2, 0) = (x1, y1)

(6, -12) = (x2, y2)

To find the slope, input the two given points into the formula used to find slope:

[tex]\frac{-12-0}{6-2}[/tex]

Simplify:

-12 - 0 = -12

6 - 2 = 4

[tex]\frac{-12}{4} = -\frac{3}{1}=-3[/tex]

The slope of the line is -3.

A square garden has an area of 53.29 square meters. What is the length of each side of the garden?

Answers

The answer is 3) 13.3m

Answer:

7.3m

Step-by-step explanation:

Area is l * w

The length and width of a square are the same, so that means we can use square root for this problem.

The square root of 53.29 is 7.3

7.3*7.3 = 53.29 (<- to double check)

Sonia Sotomayor.Let us not forget that between the appointments of Justice Sandra Day O'Connor in 1981 and Justice Ginsburg in 1992, eleven years passed. Similarly, between Justice Kaye's initial appointment as an Associate Judge to the New York Court of Appeals in 1983, and Justice Ciparicks appointment in 1993, ten years elapsed. Almost nine years later, we are waiting for a third appointment of a woman to both the Supreme Court and the New York Court of Appeals and of a second minority, male or female, preferably Hispanic, to the Supreme Court. In 1992 when I joined the bench, there were still two out of 13 circuit courts and about 53 out of 92 district courts in which no women sat. At the beginning of September of 2001, there are women sitting in all 3 circuit courts. The First, Fifth, Eighth and Federal Circuits each have only one female judge, however, out of a combined total number of 48 judges. There are still nearly 37 district courts with no women judges at all. For women of color the statistics are more sobering. As of September 20, 1998, of the then 195 circuit court judges, only two were African-American women and two Hispanic women. Of the 641 district court judges, only twelve were African-American women and eleven Hispanic women. African-American women comprise only 1.56% of the federal judiciary and Hispanic-American women comprise only 1%. No African-American, male or female, sits today on the Fourth or Federal circuits. And no Hispanics, male or female, sit on the Fourth, Sixth, Seventh, Eighth, District of Columbia or Federal Circuits.Sort of shocking, isn't it? This is the year 2002. We have a long way to go. Unfortunately, there are some very deep storm warnings we must keep in mind. In at least the last five years the majority of nominated judges the Senate delayed more than one year before confirming or never confirming were women or minorities. I need not remind this audience that Judge Paez of your home Circuit, the Ninth Circuit, has had the dubious distinction of having had his confirmation delayed the longest in Senate history. These figures demonstrate that there is a real and continuing need for Latino and Latina organizations and community groups throughout the country to exist and to continue their efforts of promoting women and men of all colors in their pursuit for equality in the judicial system.The rhetorical technique most used in this excerpt isparallelism.overstatement.ethos.shift.
