Please help me find the perimeter for the composite figure.
Answer:
A 10.28in
Step-by-step explanation:
Find the perimeter of the circle first. Because there are two half-circles, you can just find the circumference of one whole circle. 2πr is the formula. r is the radius. The circumference of the circle is 2π or 6.28.
Then add the two sides of the square. It is 2+2=4. Add 6.28 and 4.

To find:
The integer solutions for the given compound inequality.
Solution:
We have,
[tex]3\leq 3x-4<2x+1[/tex]
Case 1: [tex]3\leq 3x-4[/tex]
[tex]3+4\leq 3x[/tex]
[tex]\dfrac{7}{3}\leq x[/tex]
[tex]2.33...\leq x[/tex] ...(i)
Case 2: [tex]3x-4<2x+1[/tex]
[tex]3x-2x<1+4[/tex]
[tex]x<5[/tex] ...(ii)
Using (i) and (ii), we get
[tex]2.33...<x<5[/tex]
The integer values which satisfy this inequality are only 3 and 4.
Therefore, the integer solutions to the given inequality are 3 and 4.

how do you translate a figure in a coordinate plane?
Answer:
Answer down below
Step-by-step explanation:
When you perform translations, you slide a figure left or right, up or down. This means that on the coordinate plane, the coordinates for the vertices of the figure will change. To graph a translation, perform the same change for each point. You can identify a reflection by the changes in its coordinates.
which property of equality should you use to solve the equation for x? -3x = 21
A. The division property of equality
B. The subtraction property of equality
C. The addition property of equality
D. The multiplication property of equality
Answer:
A. The division property of equality
Step-by-step explanation:
To get x you need to find a way to get it by itself, which can be done by dividing -3 from both sides of the equation (which is the division property of equality).
For example,
-3x=21
/-3 /-3
x=21/-3
x=-7

there are 45 students In a class. if 60% of them are girls. find the numbers of girls and boys
Step-by-step explanation:
No. of students in class = 45 .
Percentage of girls = 60% .
No . of girls = 45 × 60/100 = 45 × 3/5 = 18 .
No. of boys = 45 - 18 = 27
Answer:
27 girls
18 boys
Step-by-step explanation:
Convert 60% to a decimal.
60% · .01 = 0.6Multiply 45 students by 0.6 to find the number of girls in the class.
45 * 0.6 = 27 girlsSubtract this amount from the total number of students in the class.
45 - 27 = 18 boysThere are 27 girls and 18 boys in the class.

Answer:
volume = 415800
Surface Area inside = 26370
Step-by-step explanation:
slowly added up all sides for surface area.
volume is area of trapezoid side (b1 + b2 divided by 2 multiply by height) x bottom length (70)
trapezoid Area = 106 + 34 +40 Divided by 2 then multiply by 66
The volume of the wheelbarrow is 415800 cubic centimeter.
What is Area?Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is a wheelbarrow that is used to carry wet concrete. The dimensions tray are provided in the image.
We can write the volume of the wheelbarrow as -
V = {(1/2 x 34 x 66) + (66 x 40) + (1/2 x 66 x 66)} x 70
V = {1122 + 2640 + 2178} x 70
V= 415800 cubic centimeter.
Therefore, the volume of the wheelbarrow is 415800 cubic centimeter.

Uma pesquisa realizada pela IBGE constatou que a população de uma cidade havia aumentado de 82.350 para 105.200 habitantes calcule o valor desse aumento em índices percentuais
Answer:
the value of this increase in percentage indices is 27.77%
Step-by-step explanation:
The computation of the value of this increase in percentage indices is shown below:
Given that
The population has increase from 82,350 to 105,200
So, the increase in percentage would be
= (105,200 - 82,350) ÷ (82,350)
= 22,850 ÷ 82,350
= 27.77%
Hence, the value of this increase in percentage indices is 27.77%

Last year, a lighting supplier called Bright Idea shipped a total of 37,220 lamps to its distributors. This year, the supplier shipped 29,776 lamps. What is the percent of decrease in the number of lamps shipped annually?
Answer:
25%
Step-by-step explanation:
Given data
Last years shipment= 37220 lamps
These years shipment= 29776 lamps
% Decrease= Initial-Final/Initial*100
% Decrease= 37220-29776/29776*100
% Decrease= 7444/29776*100
% Decrease= 0.25*100
% Decrease= 25%
Hence the decrease is 25%

If fixed cost of 20 article is 500 and variable cost for each article is 40. Find the total cost function? Also ,find the total cost of 90 articles?
Answer:
Cost function = 40a + 500
Cost of 90 articles = $4,100
Step-by-step explanation:
The fixed cost is $500 and it will.not change regardless of production level.
The Variable cost is $40 and increases by every additional unit produced.
Assume the number of articles produced is a.
Cost function would be:
Total cost = Variable cost * Number of articles + Fixed cost
TC = 40a + 500
Using this, the cost of 90 articles is:
= 40 * 90 + 500
= $4,100
