Find the total surface area of this cuboid.
Step-by-step explanation:
I just learned this in class lol
Find the area of all the sides.
This cubiod has 6 sides.
6 x 5 = 30
6 x 5 = 30
4 x 5 = 20
4 x 5 = 20
6 x 4 = 24
6 x 4 = 24
30 + 30 + 20 + 20 + 24 + 24 = 148
Thefore, the surface area of this cuboid is 148.
Hope this helps! If it did, please mark it as brainliest! It would help a lot! Thanks! :D

Multiplying by which number is equivalent to an increase 49.5%
Answer:
22.46
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
49.5% = 49.5/100 = 49.5 ÷ 100 = 0.495.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 49.5% of its value.
Percentage increase = 49.5% × 22.46
New value = 22.46 + Percentage increase

Answer:
Step-by-step explanation:
The line l is tangent to the circle with equation x^2 + y^2=10 at the point P.
Determine the equation of line l.
Given:
The equation of a circle is
[tex]x^2+y^2=10[/tex]
A tangent line l to the circle touches the circle at point P(1,3).
To find:
The equation of the line l.
Solution:
Slope formula: If a line passes through two points, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Endpoints of the radius are O(0,0) and P(1,3). So, the slope of radius is
[tex]m_1=\dfrac{3-0}{1-0}[/tex]
[tex]m_1=\dfrac{3}{1}[/tex]
[tex]m=3[/tex]
We know that the radius of a circle is always perpendicular to the tangent at the point of tangency.
Product of slopes of two perpendicular lines is always -1.
Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.
[tex]m\times m_1=-1[/tex]
[tex]m\times 3=-1[/tex]
[tex]m=-\dfrac{1}{3}[/tex]
The slope of line l is [tex]-\dfrac{1}{3}[/tex] and it passs through the point P(1,3). So, the equation of line l is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-3=-\dfrac{1}{3}(x-1)[/tex]
[tex]y-3=-\dfrac{1}{3}(x)+\dfrac{1}{3}[/tex]
Adding 3 on both sides, we get
[tex]y=-\dfrac{1}{3}x+\dfrac{1}{3}+3[/tex]
[tex]y=-\dfrac{1}{3}x+\dfrac{1+9}{3}[/tex]
[tex]y=-\dfrac{1}{3}x+\dfrac{10}{3}[/tex]
Therefore, the equation of line l is [tex]y=-\dfrac{1}{3}x+\dfrac{10}{3}[/tex].

Answer:
x=-2
Step-by-step explanation:
R=3x+2y
y=7, R=8
x=?
Substitute R and y with the values given
8=3x+2(7)
8=3x+14
Combine like terms
8-14=3x

34 < 6 + d
Solve the inequality
Answer:
28< 6
Step-by-step explanation:
34 < 6 + d
Subtract 6 from each side
34-6 < 6 + d-6
28< 6
Answer:
28<d
Step-by-step explanation:
Since all you need to do is find d, to do this do the inverse operation of 6 which is -6 and add them to both sides which gives you 28<d

What is 20% of 50 and what would 10% equal
Answer:
20/100 x 50 is 10
10% would be 10/100 is fraction form
I want to help you on the first thing you said,
so always consider a percent as a fraction but there denominator is ALWAYS 100 (a way to remember that is that the word "cent" means 100). The word "of" means multiplication so that means your multiplying it with 50 and just do the multiplication.
I'm really hoping you understand!

Tyrone ordered the same meal 3 days in a row. He paid a total of $12.06 for these 3 meals. How much did Tyrone pay for each meal?
$15.06
$9.06
$4.20
$4.02
Answer:
$4.02
