Answer:

(a) 33.7 cm

(b) 79.25 cm²

Step-by-step explanation:

(a)

Find the perimeter of the semicircle (circumference ÷ 2).

10 cm is the diameter of the semicircle.

The perimeter of the semicircle

= (10 × 3.14) ÷ 2

= 31.4 ÷ 2

= 15.7 cm

The perimeter of the shape

= 15.7 + 10 + 4 + 4

= 33.7 cm

(b)

Find the area of the circle then divide to 2

The formula of the area of a circle

= πr²

The radius of the circle

= 10 ÷ 2

= 5 cm

The area of the semicircle

= (3.14 × 5²) ÷ 2

= 78.5 ÷ 2

= 39.25 cm²

The area of the rectangle

= 4 × 10

= 40 cm²

The area of the shape

= 39.25 + 40

= 79.25 cm²

Step-by-step explanation:

Angle 1 2 and 3 are angles that are in a triangle and all the angles in a triangle always add up to 180

so <1 +<2 +<3=180

Answer:

If its a girl shes probaby getting bigger soon I think i she probably lost her taste in milk

Step-by-step explanation:

Answer:

Cute bunny :)

So I know that domestics are weaned off milk at about 6 weeks, so she could still be drinking, but she also could be weaning. HOWEVER, they should never loose wait during the weaning process. I would try to give her a formula (baby rabbits should be fed Kitten Milk Replacer (KMR) or goat milk, which you can buy at pet stores, or sometimes even a local veterinarian's office. Because rabbit milk is the most caloric of all mammals, we add in one tablespoon of 100% heavy whipping cream (no sugar) to each can of KMR.) and force feed it to her.

If you are not comfortable with that, you can try soaking rabbit pellets in the formula and mashing up, but there's a good chance she won't recognize that as food.

Maybe join some rabbit keeper forums or ask a local breeder for more help.

Water is the Adjacent of this right triangle. 350 yards is the length of the Hypotenuse. We have given angle B, 40 degrees.

_________________________________________________________

According to SOH CAH TOA, we use CAH (cosineΘ = adjacent/hypotenuse).

cosine40 = x/350

[multiply both sides by 350]

350 · cosine40 = x

[put calculator in degree mode]

x ≈ 268 yards

So, the distance across the water from sailboat to the island is 268 yards.

_________________________________________________________

Let's use pythagorean theorem since we already know the adjacent and hypotenuse to find the opposite (opposite is also known as height).

a^2 + b^2 = c^2

a^2 + (268)^2 = (350)^2

a^2 + 71824 = 122500

a^2 = 122500 - 71824

a^2 = 50676

[square both sides]

[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{50676}[/tex]

a = [tex]\sqrt{50676}[/tex]

a ≈ 225

So, the height, opposite, of the lighthouse is 225 yards.

Answer:

3x^2-7x+6

Step-by-step explanation:

Standard from: ax^2+bx+c

(3x+2)(x-3)

We just need to multiply these two binomials together.

When doing multiplication we get:

3x^2-9x+2x-6

3x^2-7x+6

This is in standard form so the answer is 3x^2-7x+6

Step-by-step explanation:

dekameter=10 meters

dekameter*2

20 meters

20/20=1

20 meter long pieces

Step-by-step explanation:

Since the box is a cube,

Length = Width = Height = 45m.

Volume of box = Volume of cube

= Length x Width x Height

Answer:

x = 5 - a

Step-by-step explanation:

Given

6x + a = 5(x + 1) ← distribute

6x + a = 5x + 5 ( subtract 5x from both sides )

x + a = 5 ( subtract a from both sides )

x = 5 - a

Answer:

x=5-a

Step-by-step explanation:

multiplica el paréntesis por 5

6x+a=5x+5

mueva el variable al lado izquierdo y cambie su signo

6x+a-5x=5

mueva el variable al lado derecho y cambie su signo

6x-5x=5-a

agrupe los términos semejantes

x=5-a

Answer: t=8

Step-by-step explanation:

The highest ticket price that they can charge in order to not lose money on the event will be $8.16.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

Sally's secondary school is arranging their spring melodic. The income, R, is created still up in the air by the capability R(t) = -33t² + 360t, where t addresses the cost of a ticket. The creation cost, C, of the melodic is addressed by the capability C(t) = 700 + 5t.

The highest ticket price that they can charge in order to not lose money on the event will be given as,

C(t) = R(t)

700 + 5t = -33t² + 360t

33t² - 355t + 700 = 0

Solve for 't', then we have

t = [-(-355) ± √((-355)² - 4 × 33 × 700)] / (2 × 33)

t = [355 ± 183.37] / 66

t = 5.378 ± 2.778

t = 5.378 + 2.778, 5.378 - 2.778

t = 8.16, 2.60

Answer:

14000

Explaination:

spwithvat = sp without vat + 13% of sp without vat

let, sp without vat be x.

sp with vat= x + 13% of x.

or, 13447 = x + 13/100 × x

or, 1344700 = 113x

or, x= 1344700/113

x = 11900

Let, mp be y.

sp with vat = mp - 15% of mp

or, 11900 = y - 15/100 × y

or, 1190000 = 85y

or, y= 1190000/85

y= 14000

Answer:

35

Step-by-step explanation:

The measure of an inscribed angle whose endpoints are points S and T will be 35°.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The central angle is double the angle at the periphery that was subtended by the same chords.

The central angle of arc ST is 70°.

The measure of an inscribed angle whose endpoints are points S and T is given by the half of the central angle of arc ST. Then we have

Inscribed angle = 70° / 2

Inscribed angle = 35°

The measure of an inscribed angle whose endpoints are points S and T will be 35°.

Answer:

C= 2 πr =18.85 m

Step-by-step explanation:

diameter= d= 6m

Radius = diameter/2= 6/2 = 3m

The circumference can be found by two formulas. One by using diameter and the other by using radius.

C= πd = 6* 3.14= 18.85 m

or

C= 2 πr = 2*3.14*3= 18.85 m

Using both the formulas gives the same answer.

The diameter is the line dividing the circle into half passing through the center.

The radius is half of the diameter or the lines which joins the center to the circumference of the circle.

Answer:

y = 8  

x = 12        

Step-by-step explanation:

Corresponding sides are in proportion when the polygons are similar.

(1)      7/3.5 = 3y/x                    (2)    7/3.5 = (x + 4)/y

            2 = 3y/x                                    2 = (x + 4)/y

          2x = 3y                                       2y = x + 4

          2x - 3y = 0                                -x + 2y = 4   Multiply by 2 and add to (1)

         -2x + 4y = 8

                    y = 8                               -x + 2(8) = 4

                                                           -x + 16 = 4

                                                                 -x = -12

                                                                   x = 12
