how do I solve for x?
Step-by-step explanation:
(5x + 1 ) + 14x + (4x + 5)= 180 [ sum of all angles of a triangle is 180]
height of a cone is 30cm, its slant height is 32 cm, then the radius is- ?
Given:
Height of a cone is 30cm, its slant height is 34 cm.
To find:
The radius of the cone.
Solution:
Using the Pythagoras theorem, the relation between Height, radius and slant height is
[tex]r^2+h^2=l^2[/tex]
[tex]r^2=l^2-h^2[/tex]
Where, r is radius, h is height and l is the slant height.
Putting the given values, we get
[tex]r^2=(34)^2-(30)^2[/tex]
[tex]r^2=1156-900[/tex]
[tex]r^2=256[/tex]
Taking square root on both sides.
[tex]r=\pm\sqrt{256}[/tex]
[tex]r=\pm 16[/tex]
Radius cannot be negative. So, r=16 cm.
Therefore, the correct option is b.
A skateboard ramp has a slope of 4/9. What is the measure of the angle the ramp forms with the ground
Answer:
Step-by-step explanation:
tanθ = 4/9
θ = arctan(4/9) ≈ 23.96°
The measure of the angle the ramp forms with the ground is :
-Angle is 23.96 degrees.
"Measure of the angle"Let the angle is = x
We know that tan(x) is the slope.
tan(x)=\frac{4}{9}
tanθ = 4/9θ
tanθ = arctan(4/9)
tanθ≈ 23.96°

what is 3/8 divided by 4/5
The answer you are looking for is 15/32.
To find this answer, you must first find the Least Common Denominator. The least common denominator of these 2 fractions can be found by simply multiplying the 2 given denominators together. 5 * 8 = 40.
Now that you found the LCD, you can start to solve the equation. To get 40 as the denominator for 3/8, you multiply the fraction by 5/5.
3/8 * 5/5 = 15/40.
To get 40 as the denominator for 4/5, you multiply it by 8/8. 4/5 * 8/8 = 32/40.
Finally, you divide 15/40 by 32/40. The denominators cancel out, so the numerator becomes 15 and the denominator now becomes 32.
So your answer is 15/32 (which cannotbe simplified)

hello, can i please have help on this question.thank you
Answer:
y = 4x - 3
Step-by-step explanation:
The equation for a line is y = mx +c
We need to find m which is the gradient:
To do this pick any two coordinates on the line:
(1, 1) and (2, 5)
Next divide the difference of the y coordinates by the difference of the x coordinates:
5 - 1 / 2 - 1
= 4/1 = 4
so our gradient is 4
We'd write that as y = 4x + c
Next we need to find c which is the y-intercept
To do this just simply look for where the line crosses the y-axis
This is -3
So we'd write that as y = 4x - 3
Hope this helps :)
Answer:
y=4x-3

Step-by-step explanation:
answer=
5x+1=6
5x=6-1
5x=5
x=1
Square root of 1 is 1
Answer:
√5x+1 = 6
(√5x+1)2 = (6)2
5x+1 = 36
5x -35 = 0
Add 35 to both sides
5x = 35
Divide both sides by 5
solution is :

31° F and 67° F
Step-by-step explanation:
(a)
When t = 0 then
f(0) = 31 + [tex]\frac{0}{100}[/tex] = 31 + 0 = 31° F
(b)
When t = 10 , then
f(10) = 31 + [tex]\frac{40(10^3)}{10^3+100}[/tex] = 31 + [tex]\frac{40000}{1100}[/tex] = 31 + 36.36... ≈ 67° F
