Area of two squares:

2(3x3) = 2(9) = 18

50 + 18 = 68

Answer:

68

Step-by-step explanation:

3x3=9 (top square)

3x3=9 (bottom square)

(1/2) (5) (2) = 5 (triangle 1)

(1/2) (5) (2) = 5 (triangle 2)

(1/2) (5) (2) = 5 (triangle 3)

(1/2) (5) (2) = 5 (triangle 4)

10 x 3 = 30 (middle rectangle)

9+9+5+5+5+5+30=68

Answer: 12 for the main square

Step-by-step explanation:

take the 4 and the 3 and multiply it, makes 12. you see how each stair is 6 inches and there is 3 full steps which makes it 1.50 feet. 12 x 1.50 is 18. that makes your main square. I'm sorry but I cant really help you with the steps but that was also confusing to me.

Answer:

9.32

10.116

Step-by-step explanation:

each corner is a right corner so were going to subtract 58 from 90 because all right corners are 90 degrees

90-58=32  answer A 32

after that we know that all triangles have to equal 180 so now we subtract

180-58=122 122-58=64

we subtract  58 two times because we  have 2 of the same angles

next we know that the smaller angle is 32 so now we subtract again

180-32=148 148-32=116 so y is 116

Answer:

x = 150°

Step-by-step explanation:

t1 and t2 are parallel lines, so the line going across them have identical angles. Since 150° is already given on the section that crosses t1, we can assume the same value for t2.

Answer:

C.

Step-by-step explanation:

Answer:

B. 74°

Step-by-step explanation:

n and 106° are same-side interior angles.

Same side interior angles are also supplementary angles, meaning they add to 180°.

n+106=180

n=74°

Answer:

a=17√2

Step-by-step explanation:

Hi there!

We are given a right triangle with the measure of one angle being 45°, and one of the sides being measured 17

we need to find a

first, let's find the measure of the other angle

because it's a right triangle, the sum of the acute angles are complementary, meaning they add up to 90°

let's make the unknown degree of the other angle x

so that means to find x:

45+x=90

subtract 45 from both sides

x=45°

that means the measure of the other angle is 45°

You may notice since we have two angles with the same measure, that means this triangle is isosceles.

That means the other leg (the other side that isn't marked) is also 17

of course, you could solve for a using Pythagorean theorem, but there's actually a shortcut:

in 45°-45°-90°Δ, the legs are a specific value, and the hypotenuse (the side opposite from the 90° is the value of the legs*√2 (for example, if the legs are 3, then the hypotenuse is 3√2). To remember the rule, if the legs have a measure of s, the hypotenuse has a measure of s√2

therefore the measure of a is 17√2

Hope this helps!

Answer:

Molarity = 0.4 moles per Liter

Step-by-step explanation:

If you have 0.2 moles of NaCl in 0.5 L of solution, what is the molarity? (Round answers to the nearest hundredth)

The formula formula Molarity

= n/v

Where n = number of moles

v = volume in liters

Hence

Molarity = 0.2 moles/0.5L

= 0.4 moles per Liter

Answer: Length = 10cm

Width = 6.5cm

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Therefore, the length of the rectangle will be: = (2 × x) - 3 = 2x - 3

Therefore area of a rectangle = length × width

x(2x - 3) = 65

2x² - 3x = 65

2x² - 3x - 65 = 0

2x² + 10x - 13x - 65 = 0

2x(x + 5) - 13(x + 5) = 0

(2x - 13)(x + 5) = 0

2x - 13 = 0

2x = 13

x = 13/2

x = 6.5

Width = 6.5cm

Length = 2x - 3

= 2(6.5) - 3

= 13 - 3

= 10cm

Therefore, the length of the rectangle is 10cm and the width is 6.5cm.

Answer:

r=4

nPr

20P4 = 116280

The  students can be chosen in 116280 different ways to be elected as president, vice president, treasurer and secretary.

"It is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters."

The number of ways of obtaining an ordered set of 'r' elements from a set of 'n' elements.

[tex]^{n}P_r=\frac{n!}{(n-r)!}[/tex]

For given example,

there are 20 students in a homeroom

⇒ n = 20

Students can be elected president, vice president, treasurer and secretary.

⇒ r = 4

So, using the formula of permutation, the number of different ways they  can be chosen to be elected president, vice president, treasurer and secretary would be,

[tex]\Rightarrow ^{n}P_r=\frac{n!}{(n-r)!} \\\\\Rightarrow ^{20}P_4=\frac{20!}{(20-4)!} \\\\\Rightarrow ^{20}P_4=\bold{116280}[/tex]

Therefore, these 20 students can be chosen in 116280 different ways to be elected as president, vice president, treasurer and secretary.

Answer:

La suma de los ángulos interiores de un hexágono regular es 720°

Step-by-step explanation:

Asumamos que el hexágono presentado en el enunciado sea regular, el cual es formado por seis triángulos equiláteros, Un ángulo interno del hexágono está formado dos ángulos laterales y vecinos de dos triángulos equiláteros, es decir, dos veces 60°, o sea, 120°. Si el hexágono regular tiene seis ángulos internos de igual medida, entonces la suma de los ángulos interiores es 720°.

Mengingat bahwa :

Harga palu 10 potong harga paku;

Harga selusin paku = 1200

1 lusin = 12

Jadi harga paku adalah:

1200/12

Answer: -1 8/15

Step-by-step explanation:

First turn it to improper fraction

29/5 — 22/3

87–110/15. (Here make 15 the denominator since both 3 and 5 goes in 15.

—23/15

—1 8/15

Answer:

(0.208 ; 0.372)

Step-by-step explanation:

phat = 29% = 0.29

Sample size, n = 118

The confidence interval :

phat ± margin of error

Margin of Error = Zcritical * √phat(1 -phat) / n

Zcritical at 95% = 1.96

Margin of Error = 1.96 * √0.29(0.71) / 118

Margin of error = 1.96 * 0.0417721

Margin of Error = 0.0818734

Confidence interval :

Lower boundary : 0.29 - 0.0818734 = 0.208

Upper boundary = 0.29 + 0.0818734 = 0.372

(0.208 ; 0.372)

We can be 95% confident that the proportion of adults with high blood pressure is lies within the interval (0.208 ; 0.372)
