Answer:
81
Step-by-step explanation:
here,
(a+b)=15 -------(1)
(a-b)=12 -------(2)
Equating the equation (1) and (2)
a + b = 15
a - b = 12
(b gets cancelled having opposite signs)
or, 2a = 27
or, a = 27÷2
a = 13.5
then, putting value of a in equation (1)
a+b=15
or, 13.5 + b=15
or, b=15-13.5
b=1.5
lastly,
4ab = 4×13.5×1.5
= 81

Answer:
Step-by-step explanation:
L = 3*w + 1 Given
P = 2*(L + w) Formula for Perimeter. Substitute for L
P = 2*(3w + 1 + w) Combine
P = 2*(4w + 1)
P = 58 Given
58 = 8w + 2 Remove the brackets
58 - 2 = 8w Subtract 2
56 = 8*w Divide by 8
56/8 = w
7 = w
================
Find L
L = 3*w + 1
L = 3*7 + 1
L = 22
================
Check
2L + 2W = 58
2*22 + 2*7 =? 58
44 + 14 = ? 58
58 = 58
The answer checks.
2(5x+1)−2x=2−2(3x+1)
Answer:
[tex]x = -\frac{1}{7}[/tex]
Step-by-step explanation:
2(5x + 1) - 2x = 2 - 2(3x + 1)
Use the distributive property
10x + 2 - 2x = 2 - 6x -2
Combine like terms
8x + 2 = -6x
Subtract 2 from both sides
8x = -6x - 2
Add 6x to both sides
14x = -2
Divide both sides by 14
x = -2/14 = -1/7

c = √58
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
Because we have a right triangle, we can use the Pythagorean Theorem to help us solve for missing side lengths:
7² + 3² = c²
49 + 9 = c²
58 = c²
c = √58
Answer: c = √58

The children became Americanized much faster than their parents. Often this caused painful conflicts in immigrant families. A gap appeared between the children and their parents. The parents clung to Old World customs and beliefs. The kids spoke English all day with their friends. They thought in American terms. More than anything else, they wanted to be accepted as equals in their adopted land.
Which other detail best supports the idea that children became comfortable in America more quickly than their parents?
When they left school, they looked, talked, and acted just like other American kids.
During hard times, kids had to drop out of school early. In the days before World War I, it was an accomplishment to finish grammar school.
Many kids went directly from grammar school to special vocational schools sponsored by private agencies. . . .
Students were also instructed in the fundamentals of health, hygiene, and personal grooming.
The right answer is Many kids went directly from grammar school to special vocational schools sponsored by private agencies. . .

11. 100° 12. 80° 13. 80° 14. 80° 15. 100° 16. 100°
Step-by-step explanation:
We know a straight line is 180 degrees and that m∠7 is 100 degrees.
m∠9, m∠5 and m∠11 are 100 degrees
To find m∠6, m∠8, and m∠2 we subtract 100 from 180 and get 80 degrees.
If you fill in all the degrees of the angles, you will notice a zig-zag pattern. That helps when solving these kinds of problems

Answer:
a composite number is written as a product of all of its prime factors, we have the prime factorization of the number. For example, the number 36 can be written as a product of primes as: 36 = 2² x 3². The expression 2² x 3² is said to be the prime factorization of 36.
143 dollars is divided in the ratio 2:3:6 calculate the share
Answer:
The first share is 26 dollars, the second share is 39 dollars and the last share is 78 dollars.
Step-by-step explanation:
So here is how you do this:
Whole = 2+3+6
= 11
Step 2:
first share = 2/11 multiplied by 143/1
= 143 divided by 11
= 13
= 13 multiplied by 2
= 26
Answer for the first share is 26 dollars
Step 3:
second share = 3/11 multiplied by 143/1
= 143 divided by 11
= 13
= 13 multiplied by 3
= 39
Answer for the second share is 39 dollars
Step 4:
third share = 6/11 multiplied by 143/1
= 143 divided by 11
= 13
= 13 multiplied by 6
= 78
Answer for third share is 78 dollars

The perimeter of a rectangle is 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle can be described with the equation Find the length, in centimeters, if the width is 3.6 centimeters
Step-by-step explanation:
let the unknown be x
length = x
width = 3.6 cm
Perimeter = 2 lengths + 2 widths
48 cm = x + x + 3.6 + 3.6
48 cm = 2x + 7.2
40.8 = 2x
20.4 cm = x
if you wanna check,
perimeter = 20.4 + 20.4 + 3.6 + 3.6
48 cm = 48
Using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.
Recall:
Perimeter of a rectangle (P) = 2(L + W) (relationship between the width, length and perimeter)
Given:
Width (W) = 3.6 cmPerimeter (P) = 48 cmLength (L) = ?Using the relationship between the dimension of a rectangle and its perimeter, the following equation would be derived:
48 = 2(L + 3.6)
Solve for the value of L48 = 2L + 7.2
Subtract 7.2 from each side48 - 7.2 = 2L
40.8 = 2L
Divide both sides by 220.4 = L
L = 20.4 cm
Therefore, using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.

The scale of dilation is the number that you multiply one side of the original triangle to get its corresponding side on the new triangle. In this case, it can be seen that AB corresponds to A'B', and so you divide A'B' by AB (6 divided by 4) to find that the scale factor is 6/4, or 3/2. If you do this with any of the other sides you will get the same answer.

boy a and boy b are pushing a heavy table in the west direction at the same time with 10 units of force each.what is the net force acting on the object ?in which direction the table will move?
Answer:
20 n
Step-by-step explanation:
as both are exerting force on the same side i.e. to the west side with 10 N each the total net force is 10+10=20N and the table will move to the west side....
Thank you
The net force acting on the object will be 20 units and the direction will be the same as the direction of force applied.
What is gravitational force?All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.
As we know, the gravitational force is given by:
[tex]\rm F = \dfrac{Gm_1m_2}{r^2}[/tex]
Where G is the gravitational constant.
m1 and m2 are masses.
r is the distance between the masses.
It is given that:
Boy 'a' and boy 'b' are pushing a heavy table in the west direction at the same time with 10 units of force each
The table will shift to the west side since both are applying 10 N of force to the same side, i.e., the west side, for a total net force of 10+10=20 N.
Total net force = 10 + 10 = 20 units
Thus, the net force acting on the object will be 20 units and the direction will be the same as the direction of force applied.

The product in scientific notation is 1.32 × 10²⁵.
What is scientific notation?Scientific notation is a method for expressing numbers that are too large or too small to be easily written in decimal form (usually resulting in a long string of digits). It is known as standard form, scientific form, or standard index form. Scientists, mathematicians, and engineers all use this base ten notation because it can simplify some arithmetic operations. It is typically referred to as "SCI" display mode on scientific calculators.
Non-zero numbers are written in the form (m x n¹⁰) in scientific notation.
Given (11 x 10¹¹)(12 x 10¹²)
11 x 10¹¹ x 12 x 10¹²
132 x 10¹¹⁺¹² (base same add powers)
132 x 10²³ (132 can be written as 1.32 x 100)
1.32 x 100 x 10²³
1.32 x 10²³⁺²
1.32 x 10²⁵
Therefore the scientific notation is 1.32 x 10²⁵.
