If Pietra walked 11 miles during the week, how many miles did the two girls walk together?

Step-by-step explanation:

scalar multiplication is simply done by multiplying every term of the matrix by the factor.

-1/5 A =

-5×-1/5 -15×-1/5 10×-1/5

-30×-1/5 20×-1/5 -25×-1/5

=

1 3 -2

6 -4 5

for the addition of 2 matrices imagine that each one is on a transparent slide, and you simply move both slides on top of each other, and you add all numbers for a position, that overlap each other for that position.

so,

-1/5 × A + B =

1+4 3+5 -2+ -7

6+7 -4+0 5+ -5

=

5 8 -9

13 -4 0

The equation that represents the distance, d, between the friends after t hours is d = √(3250t²)

From the question, we are to write an equation for the distance between the friends after t hours

From the given information,

"One heads North at 45 miles per hour, while the other heads East at 35 miles per hour"

First, we will calculate the distance each of them has traveled after t hours

Using the formula,

Distance = Speed × Time

Distance covered by the friend that heads North is

Distance = 45 × t

Distance = 45t

Distance covered by the friend that heads East is

Distance = 35 × t

Distance = 35t

Now, for the distance, d, between the two friends after t hours

Using the Pythagorean theorem, we can write that

d² = (45t)² + (35t)²

d² = 2025t² + 1225t²

d² = 3250t²

d = √(3250t²)

Hence, the equation that represents the distance, d, between the friends after t hours is d = √(3250t²)

Step-by-step explanation:

The area of the square B is a 169 and increase in the area w.r.t to the square A is 48.

According to the statement,We have to find that the Area of the square B.

So, For this purpose, we know that the

The Area is defined because the total space concerned by a flat (2-D) surface or shape of an object.

From the given information:

The area of Square A is 121 square inches. The length of every side of Square B is 2 inches longer than the length of every side of Square A.

Then

We know that the realm of the square is a^2

Then

Given area of the square = 121.

Area = [tex]A^2[/tex]

121 = [tex]A^2[/tex]

[tex]A = \sqrt{121}[/tex]

A = 11.

The side of the square a is 11.

And The side of the square B = 11+2

The side of the square B = 13

The Area of the square B = Side * Side

Area of the square B = 13* 13

Area of the square B = 169.

Now, Increase in the area = 169 -121

Increase in the area = 48.

So, The area of the square B is a 169 and increase in the area w.r.t to the square A is 48.

The dimensions of the box is a height of 8 inches, width of 32 inches and length of 40 inches.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of the shipping box. Hence:

h = (1/5) * length

Length = 5h

h = (1/4) * width

Width = 4h

Volume of the box = height * width * length = h * 5h * 4h

Width = 4h

h = 8 in

Length = 5(8) = 40 in

Width = 4(8) = 32 in

The dimensions of the box is a height of 8 inches, width of 32 inches and length of 40 inches.

Answer:

The values of x for the inequality |x +9| ≥ −6 are x = -3, -15.

Step-by-step explanation:

An equation of inequality is given that is |x +9| ≥ −6 that is to be solved for x.

Firstly let us understand what is an inequality;

In mathematics, inequalities specify the connection between two non-equal numbers. To be unequal is to be unequal.

Now, let us consider the given inequality;

=> |x +9| ≥ −6

Let us take this equation this way to solve which is the negative value of  terms of the bar;

=> -(x + 9) = −6

=> -x = -6 + 9

=> x = -3

Now, Let us take this equation this way to solve which is the positive value of terms of the bar;

=> x + 9 = −6

=> x = -6 - 9

=> x = -15

Therefore, the values of x for the inequality |x +9| ≥ −6 are x = -3, -15.
