Plz help me I can’t solve it I try it so many ways!!!

Answer:

Step-by-step explanation:

4.5+173=177.5.

122.5 does not equal 0.

Answer:

Solution given:

length [l]=9

breadth [b]=4

height[h]=3

Now

area of base=l*b=9*4=36

Volume of rectangular

pyramid =⅓area of base*height

=⅓*36*3

=36 cubic unit is a required volume.

Answer: [tex]49.79\ m[/tex]

Step-by-step explanation:

Given

The volume of the spherical solid is [tex]V=123,456\ m^3[/tex]

It is melted to form a solid cube

Suppose the edge length of the cube is [tex]a[/tex]

The volume of the sphere is  [tex]\frac{4}{3}\pi r^3[/tex]

[tex]\Rightarrow 123,456=a^3\\\Rightarrow a^3=123,456\\\text{Factorising 123,456}\\\Rightarrow a^3=2^6\times 3\times 643\\\\\Rightarrow a=\sqrt[3]{2^6\times 3\times 643} \\\\\Rightarrow a=4\sqrt[3]{ 3\times 643}\\\\\Rightarrow a=49.79\ m[/tex]

Answer:

P = 12x - 9

Step-by-step explanation:

To find the perimeter of the triangle, we just add all of the sides.

The formula is:

P = a + b + c

Given:

a = 5x - 6

b = 4x - 3

c = 3x

Work:

P = a + b + c

P = 5x - 6 + 4x - 3 + 3x

P = 12x - 9

Answer:

-19x + 12

Step-by-step explanation:

         5x   - 4

-4x  -20x  16x

-3    -15x    12

_____________

-20x + 16x + (-15x) + 12

= -19x + 12

Answer:

Step-by-step explanation:

Arc length of a circle is given by,

Arc length = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = Central angle subtended by the arc

r = Radius of the circle

From the given picture,

θ = 45°

r = 1 unit

Therefore, arc length = [tex]\frac{45}{360}(2\pi r)[/tex]

                                    = [tex]\frac{1}{8}(2\pi r)[/tex]

                                    = [tex]\frac{2\pi }{8}(r)[/tex]

                                    = [tex]\frac{\pi}{4}(r)[/tex]

Arc length = [tex]\frac{\pi}{4}(1)[/tex] units

                 = [tex]\frac{\pi }{4}[/tex] units

Angle θ has a measure = [tex]\frac{45}{360}\times \pi[/tex]

                                       = [tex]\frac{\pi}{8}[/tex] radians

Answer:

B. M(-9, -4) M'(-5,2)

Step-by-step explanation:

(x,y)-- (x+4, y+6)

when you replace it with the values,

(-9,-4)--(-9+4, -4+6)

=(-9,-4)--(-5,2)

Answer:

[tex]81\:\text{men}[/tex]

Step-by-step explanation:

Since there are 3 men for every 5 women in the company, for each women there will be [tex]\frac{3}{5}[/tex] men.

Therefore, we can write the following system of equations:

[tex]\begin{cases}\frac{3}{5}w=m,\\w+m=216\end{cases}[/tex]

Solving, we get:

[tex]w+\frac{3}{5}w=216,\\\frac{8}{5}w=216,\\w=216\cdot \frac{5}{8}=135\:\text{women}[/tex]

Therefore, there are [tex]216-135=\boxed{81\:\text{men}}[/tex] in the company.

Answer:

58 inches

Step-by-step explanation:

Perimeter means the sum of length of all sides of a figure.

So, the perimeter of this triangle would also be the sum of the length of its sides.

It has 3 sides.

19 in, 16 in and 23 in.

So, its perimeter equals 19 + 16+ 23

which equals 58 inches!

So, the perimeter would be 58 inches.!

Answer:

you should factor the expressions!

Step-by-step explanation:

for example: x²-9=(x+3)×(x-3) you know how to do factoring, right?

Answer:

[tex]\$316.80\:\text{a week}[/tex]

Step-by-step explanation:

If a 40% income tax is deducted from Mrs. Frank's income, her total/net income will be 60% of her income before income tax.

Therefore, her net pay is equal to [tex]528\cdot 0.6=\boxed{\$316.80\text{ a week}}[/tex].

Answer:

46

Step-by-step explanation:because

Answer:

Step-by-step explanation:

The triangle is isosceles. That means that the unmarked side is also x

The Pythagorean Theorem applies

x^2 + x^2 = 4^2

2x^2 = 16                 Divide by 2

2x^2/2 = 16/2

x^2 = 8

x^2 = 2 * 2 * 2

sqrt(x^2) = sqrt(2 * 2 * 2)

The rule is take one of a pair of factors out of the root sign and through the other member of the pair away. The third 2 stays under the root sign.

x = 2sqrt(2)

Answer: 3.2/1.53=x/41.5

cross multiply

1.53x=(3.2)(41.5)

1.53x=132.8

x=132.8/1.53

x=86.79738

x=87 meters

Answer:

  (a+b)²/b

Step-by-step explanation:

Invert the denominator fraction and multiply.

  [tex]\dfrac{a^2+ab}{a-b}\div\dfrac{ab}{a^2-b^2}=\dfrac{a(a+b)}{a-b}\cdot\dfrac{a^2-b^2}{ab}\\\\=\dfrac{a(a+b)(a+b)(a-b)}{ab(a-b)}=\boxed{\dfrac{(a+b)^2}{b}}[/tex]

Answer:

56 feet²

Step-by-step explanation:

To make this question easier, we can divide the shape into two parts.

Firstly lets find the first part (the bottom square)

We know that its length is 4 and we can find its height by doing 8 - 4 = 4

4 * 4 = 16

Then we do 10 * 4 = 40 to find the top bit.

We add these together to make 16 + 40 = 56

The total area is 56 feet²

Answer: 20 meters

Step-by-step explanation:

Squares will have equal sides. Since the perimeter is all the sides added up together add 5+5+5+5 to get 20

Hope you have a lovely day!

Answer:

The answer is 20 meters.

Step-by-step explanation:

Since a square has 4 equal sides, and we know that one side of this square is 5 meters long, then we multiply 5 (meters) by 4 (sides).

5 × 4 = 20

The square is 20 meters long! I hope this helps! :)
