Answer:
103
Step-by-step explanation:
We know supplementary angles equal 180 degrees. So the problem will be: 180 - 77 = 103
Answer:
103 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Thus, the supplement of 77 degrees is (180 - 77) degrees, or 103 degrees.

a gift box has the shape of a rectangular prism. how much wrapping paper do you need to cover the box?
Answer:
You will need 411 inches
Step-by-step explanation:
To solve this problem you have to find the surface area.
First, multiply.
7 × 13 = 91
16 × 7 = 112
16 × 13 = 208
Then add.
91 + 112 + 208 = 411
You will need 411 inches of wrapping paper to cover the box.

The length of a garden is 25 m. Find the width knowing that the area is between 300 m2 I need it now pls
Answer: 12m
Step-by-step explanation:
Assuming the garden is a rectangular one, the area can be calculated by the formula:
Area = Length * Width
Given the length, one can find the width by making it the subject of the formula:
300 = 25 * Width
Width = 300 / 25
= 12 m

Cindy's square-shaped garden has side lengths of x ft. She will plant 5 tulip bulbs per square foot. Write a function g to model the number of bulbs she should plant. How many bulbs will she plant if the garden has a side length of 8 feet? for this problem what is the function we need to write g(x)=?
Answer:
The total number of bulbs are "320 bulbs".
Step-by-step explanation:
According to the question,
The square garden's side length,
x = 8 feet
Number of tulip bulbs she plant,
= 5
Now,
As per the question, the area of square will be:
⇒ [tex]A=x^2[/tex]
[tex]=(8)^2[/tex]
[tex]=64[/tex]
hence,
The total number of bulbs will be:
⇒ [tex]n=A\times 5[/tex]
[tex]=64\times 5[/tex]
[tex]=320 \ bulbs[/tex]
Thus the above is the correct solution.

Answer:
13 / 25 were boys
14 / 25 were girls
Step-by-step explanation:
Of the girls 10 said no and 4 said yes
10 + 4 = 14 so she asked a total of 14 girls
Of the boys 8 said yes and 5 said no
8 + 5 = 13 so she asked a total of 13 boys
she asked 14 girls and 13 boys
14 + 13 = 25 so she asked a total of 25 people
Out of the 25 people she asked 13 of them were boys
So 13 out of 25 people we boys
or 13 / 25
which means 14 out of 25 were girls
or 14 / 25

The ratio of boys to girls at the Milwood School is 4 to 5. If there are a total of 27
children at the school, how inany boys attend the Milwood School?
Answer: 12 boys attend Millwood School.
Step-by-step explanation:
Yeah. It just makes sense. I am bad at explaining. Sorry!
The ratio shows how many times one value is contained in another value.
The ratio of boys to girls at the Milwood School is 4 to 5.
The number of girls that attended the Milwood school is 15.
The number of boys that attended the Milwood school is 12.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of boys to girls at the Milwood School is 4 to 5.
Total number of children = 27
Let the number of boys = 4x
Let the number of girls = 5x
Now,
4x + 5x = 27
9x = 27
x = 3
Now,
The number of boys = 4x = 4 x 3 = 12
The number of girls = 5x = 5 x 3 = 15
Thus,
The number of boys that attended the Milwood school is 12.

Step-by-step explanation:
Find the sum of the first eight terms of a geometric series is the fourth term of 25 in the constant ratio is 3/5 . Answer your answer as a decimal rounded to two places
25 = a1(1- (0.6)⁴)/(1-0.6)
25 = a1 (1- 0.13)/(0.4)
10 = a1(0.87)
a1 = 11.49
S8 = 11.49(1- (0.6)^8)/(1-0.6)
= 11.49(1-0.017)(1-0.6)
= 11.49(0.983)/0.4
= 28.24
The sum of the first eight terms of the given geometric series is; 28.24
How to find the sum of a geometric series?
We are told that the sum of the first four terms of the geometric series is 25. Thus, formula for sum of n terms of a geometric series is;
Sₙ = a(1 - rⁿ)/(1 - r)
where;
a is first term
r is common ratio
Thus;
25 = a(1 - (0.6)⁴)/(1 - 0.6)
25 = a(1 - 0.13)/(0.4)
10 = 0.87a
a = 11.49
Thus, sum of the first 8 terms of the series is;
S₈ = 11.49(1 - 0.6⁸)/(1 - 0.6)
S₈ = 11.49(1 - 0.017)(1 - 0.6)
S₈ = 28.24

The mean of four numbers is 40. Three of the four numbers are 35, 41, and 41. What
is the fourth number?
Answer:
43
Step-by-step explanation:
Use the mean formula:
mean = (sum of elements) / (number of elements)
Let x represent the fourth number, and solve for x:
mean = (sum of elements) / (number of elements)
40 = (35 + 41 + 41 + x) / 4
40 = (117 + x) / 4
160 = 117 + x
43 = x
So, the fourth number is 43

Step-by-step explanation:
simplify upper n lower fraction of LHS:
2^x+22^x+222^x
= 2^x*1 + (2*11)^x + (2*111)^x
= 2^x*1 + 2^x*11^x + 2^x*111^x
= 2^x*(1+11^x+111^x)
3^x+33^x+333^x
= 3^x*1 + (3*11)^x + (3*111)^x
= 3^x*1 + 3^x*11^x + 3^x*111^x
= 3^x*(1+11^x+111^x)
so LHS
= 2^x*(1+11^x+111^x) / (3^x*(1+11^x+111^x))
= 2^x / 3^x
= (2/3)^x
RHS = 9/4
= (3^2/ 2^2)
= (3/2)^2
= (2/3)^(-2)
so x = -2

Find the volume of the composite solid. Round your
anwser to the nearest hundredth.
Answer:
226.19 [tex]cm^{3}[/tex]
Step-by-step explanation:
Vol. of cone = Bh/3 where B is the area of the base(circle) and h is the height of the cone.
r = 3 h = 3
V = [tex]\frac{\pi *3^{2}*3 }{3}[/tex] = 9π
Vol. of the cylinder = Bh where B is the base(circle) and h is the height of the cylinder.
r = 3 h = 10 - 3 = 7
V = [tex]\pi *3^{2} * 7[/tex] = 63π
Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19
Volume is a three-dimensional scalar quantity. The volume of the composite figure will be 226.194cm³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the composite solid is the sum of the slanted cylinder and the cone. Therefore, the volume will be,
Volume = Volume of cone + Volume of slant cylinder
= [(1/3)πr²h] + [πr²H]
= [(1/3)×π×(3)²×3] + [π×(3)²×7]
= 28.274 cm³ + 197.920 cm³
= 226.194 cm³
Hence, the volume of the composite figure will be 226.194cm³.
