Answer:

B 13

Step-by-step explanation:

it is an equilateral triangle  the degree inside is all 60 so that mean that the side are all the same to

see a triangle has a total of 180 degrees.it already listed 120 degrees so 180-120=60

so since all the degree are all the same number it has to be an equilateral triangle.

Radius of 1 solid iron sphere =r

→ Volume =34πr3

→ Volume of 27 solid iron

spheres =27x34πr3

→ 34πr'3=27x34πr3

r'3=2πr3

→r'=3r

(ii) Surface area =4+πr2

SA r'=4πr'2

=4π(3r)2=36πr2

S'S=36πr24πr2=91=1:9

Answer:

The angles are 53° and 127°.

Step-by-step explanation:

Supplementary angles add up to 180°. So now that we know that, we must now use algebra.

I will use x and x-74 in my equation.

So the equation:

x+x-74=180.

=2x-74=180

2x=180+74

2x=254

x=127​°

So the other angle is 127-74=53

The angles are 53 and 127.

Let's solve

in ∆GNK

Apply pythagorean theorem

[tex]\\ \sf\longmapsto NK^2=GN^2-GK^2=130^2-47^2=16900-2209=14691[/tex]

[tex]\\ \sf\longmapsto NK=\sqrt{14691}[/tex]

[tex]\\ \sf\longmapsto NK=121(Approx)[/tex]

If you observe the traingle

[tex]\\ \sf\longmapsto LJ^2=JN^2-LN^2[/tex]

[tex]\\ \sf\longmapsto LJ^2=130^2-78^2[/tex]

[tex]\\ \sf\longmapsto LJ^2=16900-6084[/tex]

[tex]\\ \sf\longmapsto LJ^2=10816[/tex]

[tex]\\ \sf\longmapsto LJ=\sqrt{10816}[/tex]

[tex]\\ \sf\longmapsto LJ=104[/tex]

So

in ∆HNL

[tex]\\ \sf\longmapsto HN^2=104^2+78^2[/tex]

[tex]\\ \sf\longmapsto HN^2=10816+6084[/tex]

[tex]\\ \sf\longmapsto HN^2=16900[/tex]

[tex]\\ \sf\longmapsto HN=\sqrt{16900}[/tex]

[tex]\\ \sf\longmapsto HN=130[/tex]

In the queston given, we have a quadratic equation which we are asked to solve only with quadratic formula. The solution of the equation are 1 and 3/2

Data;

Quadratic formula is used to solve quadratic equations and it is given as

[tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]

Let's substitute the values and solve the quadratic equation.

[tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}\\x = \frac{-5 +- \sqrt{5^2 - 4*(-2)*(-3)} }{2*(-2)} \\x = \frac{-5+-\sqrt{25-24} }{-4} \\x = \frac{-5+- \sqrt{1} }{-4} \\x = \frac{-5+1}{-4} \\x= \frac{-4}{-4} = 1\\or\\x = \frac{-5-1}{-4} \\x = \frac{3}{2}[/tex]

From the calculations above, the solutions to this equation are 1 or 3/2

Answer:

78.54 ft^2

Step-by-step explanation:

The area of a circle is pi*r^2

R is the radius, which is half the diameter, so 5.

5^2 is 25, and that times pi is about 78. 54. Because this is feet and area is squared, our unit is ft^2

Answer:

replace the value of x but x cannot be 0 or a negative number

Step-by-step explanation:

for example:

replace x with 1===> y will be =0 cuz ln(1) = 0

replace x with 2==> y will be = 0.7 cuz ln(2)= 0.7

replace x with 3==> y will be = 1.1 cuz ln(3)= 1.1

replace x with 4==> y will be =  1.4 cuz ln(4)= 1.4
