Answer:
3:7
Step-by-step explanation:
To simplify the ratio 30:70, we find the greatest common divisor of 30 and 70, and then we divide 30 and 70 by the greatest common divisor. The greatest common divisor that you can use to simplify 30:70 is 10. This means the answer to ratio 30:70 simplified is: 3:7.

Answer:
x = 4
Step-by-step explanation:
We use the formula:

x² + 9 = 25
x² = 16
[tex]\sqrt{x^2} =\sqrt{16}[/tex]

have a nice day :)Step-by-step explanation:
solution:
A.
relation between hypotenuse and base is given by cos angle
so
[tex] \cos(ø) [/tex]=base/hypotenuse=11/x
cos37°=11/x
x=11/(cos37°)=13.77units
side indicated =x=13.77units
solution:
B.
relation between perpendicular and base is given by tan angle
so
[tex] \tan(ø) [/tex]=perpendicular/base=4/13
ø=tan-¹ (4/13)=17.10°
angle indicated =ø=17.10°

Roscoe is locked outside his house.The only unlocked window is on the 2nd floor which is 24 feet from the ground. He will have to borrow a ladder from the neighbors house and place it 7 feet from the house. What length of ladder does he need to reach the 2nd floor safely
Answer:
25 feets
Step-by-step explanation:
The scenario above can be modeled and solved Using Pythagoras :
Height to second floor = 24 feets
Horizontal Distance between foot of ladder and wall = 7 feets
Let length of ladder = x
The lengtb of ladder here is the hypotenus
Recall:
Hypotenus = sqrt(opposite² + adjacent²)
Hence,
x = sqrt(24² + 7²)
x = sqrt(576 + 49)
x = sqrt(625)
x = 25
Hence, length of ladder = 25 feets

Answer:
[tex] m\angle EFG = 52\degree[/tex]
Step-by-step explanation:
By inscribed angle theorem:
[tex] m\angle EFG =\frac{1}{2} m\angle EDG[/tex]
[tex] (x+51)\degree =\frac{1}{2}(10x +94)\degree [/tex]
[tex] (x+51)\degree =\frac{1}{2}\times 2(5x +47)\degree [/tex]
[tex] (x+51)\degree =(5x +47)\degree [/tex]
[tex] x+51 =5x +47 [/tex]
[tex] x+51 - 47=5x - x[/tex]
[tex] 4=4x[/tex]
[tex] x=\frac{4}{4}[/tex]
[tex] x=1[/tex]
[tex] \because m\angle EFG = (x+51)\degree[/tex]
[tex]\therefore m\angle EFG = (1+51)\degree[/tex]
(plug x = 1)
[tex] \therefore m\angle EFG = 52\degree[/tex]

Help me with #6 Please
Answer:
4 - pi
Step-by-step explanation:
we see that the inner square leg is 2 inch because its radius + radius
which is 1+1 (two circles diameters are 4 inches, so one circle has 1 inch radius) square area = 4 inches.
we subtract the area of 4 circle quadrants which is a circle area.
area of the circle is pi r^2, r = 1 so A = pi inch
the shaded region is (4 - pi) inch squared.
Which is a solution of 2x(8x + 5) (7x – 13) = 0?
Answer:
Step-by-step explanation:
This has 3 solutions
2x = 0 Divide by 2
x = 0
8x + 5 = 0 Subtract 5 from both sides
8x = - 5 Divide by 8
x = - 5/8
x = -0.625
7x - 13 = 0 Add 13 to both sides
7x = 13 Divide by 7
x = 13/7
x = 1.86

For which of the following equations is (-3,-2) not a solution?
Answer:
-5
Step-by-step explanation:
Just add the numbers and if they both got negative numbers it is negative
No equation in the answer choices has a solution pair of (-3,-2) as as evident from the computation below.
Solution pair for EquationsTo determine which equations are not satisfied by the solution pair; (-3,-2), we must substitute the solution pair into each equation as follows;
−3x=4y−6; -3(-3) = 4(-2) - 6; 9 = -14; Falsey=x−1; -2 = -3 -1; -2 = -4; False5x+2y=−16; 5(-3) + 2(-2) = -16; -19 = -16; False2(-2) - 3(-3) = 0; +5 = 0; FalseIt follows form the computation above that, the solution pair is not a solution to any of the equation choices.
Remarks:
Select one: a. −3x=4y−6 b. y=x−1 c. 5x+2y=−16 d. 2y−3x=0

Step-by-step explanation:
All 3 angles add up to be 180 due to sum of angles in a triangle.
Given this fact,
[tex]38 - 5x + 83 + 24 = 180 \\ 145 - 5x = 180 \\ - 5x = 180 - 145 \\ - 5x = 35 \\ x = 35 \div - 5 \\ = - 7[/tex]
Answer:
(38 - 5x)⁰ + 83⁰ + 24⁰ = 180⁰
<=> (38 + 83 + 24) - 5x = 180
<=> 145 - 5x = 180
<=> 5x = 145 - 180
<=> 5x = - 35
<=> x = - 7

A ladder leans against the side of a house the top ladder is 16 ft from the ground the bottom of the ladder is 12 ft from the side of the house find the length of the ladder if necessary round your answer to the nearest tenth
Answer:
[tex] {h =}^{2} = {p}^{2} \: + {b}^{2} [/tex]
[tex] {h}^{2} = {16}^{2} + {12}^{2} [/tex]
[tex] {h}^{2} = 256 + 144[/tex]
[tex]h = \sqrt{400} [/tex]
[tex]h = 20[/tex]
therefore the length of the ladder is 20ft
A cone has a volume of 565.2 cubic millimeters and a radius of 6 millimeters. What is its
height?
Use I 3.14 and round your answer to the nearest hundredth.
Answer:
h = 15 mm
Step-by-step explanation:
Given that,
The volume of a cone, V = 565.2 cubic millimeters
The radius of the cone, r = 6 mm
We need to find its height. The formula for the volume of the cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]
Where
h is the height of the cone
[tex]h=\dfrac{3V}{\pi r^2}\\\\h=\dfrac{3\times 565.2 }{3.14 \times 6^2}\\\\h=15\ mm[/tex]
So, the height of the cone is equal to 15 mm.
What is FG?
NEED HELP QUICK!!
Answer:
FG = 18
Step-by-step explanation:
FD is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{24}{54}[/tex] = [tex]\frac{x}{x+10}[/tex] ( cross- multiply )
54x = 24(x + 10)
54x = 24x + 240 ( subtract 24x from both sides )
30x = 240 ( divide both sides by 30 )
x = 8
Then
FG = x + 10 = 8 + 10 = 18
