Answer:
perimeter of a rectangle
=2×(L+B)
=2×(4.3+3.4)
=2×7.7
=15.4
Area of a rectangle
=L×B
=4.3×3.4
=146.2
Answer:
Step-by-step explanation:
The formula for the perimeter of a rectangle of length L and width W is
P = 2L + 2W. In this particular problem, P = 2(3.4 cm) + 2(4.3 cm), or
P = 6.8 cm + 8.6 cm, or P = 15.4 cm
The formula for the area of a rectangle of length L and width W is A = L * W.
In this problem, the area is A = (3.4 cm)(4.3 cm) = 14.62 cm^2 = A
what is the vaule of x ?
Answer:
5
Step-by-step explanation:
(5x + 10) + 55 = 90
5x + 10 + 55 = 90
5x + 65 = 90
5x + 65 - 65 = 90 - 65 (the 65 crosses off)
5x = 25
5x/5 = 25/5
x = 5

Step-by-step explanation:
Answer:
12%
Step-by-step explanation:
3 is 12% of 25. So you would have a 12 percent chance of getting a white marble.
3 ÷ 25 = 0.12 = 12%
Percent formula

What is the common ratio for geometric sequence: 5,15,45,135 ?
Answer:
the common ratio is 3
Step-by-step explanation:
to solve for the common ratio, I like to take the second term and divide it by the first term
15/5 = 3
then I will check the rest of the terms
15*3 = 45
45*3 = 135
It looks like the common ratio is correct!
A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother. Which equation expresses the weight of the mother? * n – 1,400 = 7,437 n + 1,400 = 7,437 n x 7,437 = 1,400 n + 7,437 = 1,400
Answer:
n – 1,400 = 7,437
Step-by-step explanation:
A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.
Let us represent :
Weight of the mother elephant = x
Weight of the baby elephant = y
A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.
y = x - 7437 pounds
Hence,
1400 pounds = x - 7437 pounds
The weight of the mother elephant =
x = 1400 pounds + 7437 pounds
Therefore, the equation that expresses the weight of the mother where, the weight of the mother = n is:
n – 1,400 = 7,437
Use matrix method to solve 2+y=3,x+2y=9
Answer:
x= -1, y= 5
Step-by-step explanation:
Please see the attached picture for the full solution.
Matrix A is called the coefficient matrix. This means that its elements are the coefficient of x and y. In matrix X, write the unknown variables. Then write the constants in matrix B.
Theorem:
[tex]{A}^{ - 1} A = I[/tex]
☆ I is an identity matrix and can be treated as 1 when multiplying.
[tex] {A}^{ - 1} = \frac{1}{ |A| } adj(A)[/tex]
☆ [tex] |A|[/tex] is the determinant of A
☆ adj(A) is the adjoint of matrix A

What is the slope-intercept form of this equation?
8x + y = 12
Answers:
Y= 2/3x + 2
Y= 4/3x + 6
Y= -4/3x + 6
Y= -4/3x + 2
Answer:
y = -8x + 12
Step-by-step explanation:
Slope intercept form: y = mx + b
m ---> Slope & b ----> y-intercept
8x + y = 12
Subtract 8x from both sides
y = -8x + 12
Dante is mailing a box with a length of nine 1/2 inches a width of 8 inches and a height of 6 inches what is the volume of the box
Answer:
456 in³
Step-by-step explanation:
To find the volume of the box, use the volume formula, V = lwh
Plug in the length, width, and height:
V = lwh
V = (9.5)(8)(6)
V = 456
So, the volume of the box is 456 in³

Use the distributive property to rewrite the expression -1 (x -2)
Answer:
Step-by-step explanation:
Distributive property: a*(b + c) =(a*b) + (a*c)
Multiply x by (-1) and (-2) by (-1)
-1(x - 2 ) = (-1)*x - 2 *(-1)
= -x + 2
