Answer:

Step-by-step explanation:

We can let X, Y, and Z represent the ages of Xavier, Yolanda, and Zed, respectively.

1) X = Y -9 . . . . . . Xavier is 9 years younger than Yolanda

2) Y = Z +7 . . . . . Yolanda is 7 years older than Zed

3) X +Y = 25 . . . . the sum of ages of Xavier and Yolanda is 25

_____

Additional comment

The first equation can be substituted into the last to give 2Y-9=25 ⇒ Y=17. The other ages are easily computed once you know this. X=8, Z=10.

Answer:

13.15 in

Step-by-step explanation:

We know that to get area for a square is

Side x side = side ^2

(normally we would put an algebra for it, but i just write i like this so that it is easier to understand)

OK therfore I can say

Area = side ^2

173 = side ^2

When u bring a square over, it becomes square root

So...

Square root 173 = side

Side = 13.15in

Answer:

13.15 in

Step-by-step explanation:

the side length = √173 = 13.1529464..= 13.15 in.

Explanation:

Ignore the denominators for now.

The numerators -11 and 9 add up to -11+9 = -2

Then we place that result over the common denominator 21 to get the final answer -2/21

This trick only works if the denominators are all the same. If not, then you'll need to find the LCD first before you can add the fractions. Luckily, all of the denominators were the same at 21.

(-11/21)+9/21

= (-11+9)/21

= -2/21.ans...

Answer:

The mean is 70.8.

Step-by-step explanation:

Finding the arithmetic mean, or average, can be found by adding up all the numbers divided by the total count of those numbers.

So, we have :: 60, 67, 71, 76, 80.

These numbers added together = 354.

There are 5 numbers listed.

354 / 5 = 70.8.

Answer:

yes

Step-by-step explanation:

e.g if two set,set A and B have 4 elements in both

if A (abcd) and B(3728) they both have the same number of elements BUT different elements.

So the answer is yes..

I hope this help

Step-by-step explanation:

The sum of angles in a triangle = 180°

Therefore,

(7x - 6)° + (5x - 10)° + 52° = 180°

Collect the like terms and add

7x + 5x - 6 - 10 + 52 = 180°

12x + 36 = 180°

12x = 180 - 36

12x = 144

x = 144 / 12

x = 12°

From the above diagram,

Angle A = 7x - 6

A° = 7(12) - 6

A° = 84 - 6

A = 78°

f = (9c/5) + 32

Answer:

The water level would rise by [tex]5\; \rm cm[/tex].

Step-by-step explanation:

Assume that the initial water level is [tex]h\; \rm cm[/tex].

Before the cube was placed in the tank, the volume of the water was the same as the volume of a rectangular prism with a length of [tex]160\; \rm cm[/tex], a height of [tex]80\; \rm cm[/tex], and a height of [tex]h\; \rm cm[/tex]:

[tex]\begin{aligned} & 160\; {\rm cm} \times 80\; {\rm cm} \times h\; {\rm cm} \\ =\; & (80 \times 160) \, h \; \rm cm^{3} \end{aligned}[/tex].

Let the rise in the water level in the tank be [tex]x\; \rm cm[/tex]. The new water level would be [tex](x + h)\; \rm cm[/tex].

The volume of the water and the submerged cube, combined, would be the same as that of a rectangular prism with a length of [tex]160\; \rm cm[/tex], a width of [tex]\rm 80\; \rm cm[/tex], and a height of [tex](x + h)\; \rm cm[/tex]:

[tex]\begin{aligned} & 160\; {\rm cm} \times 80\; {\rm cm} \times (x + h)\; {\rm cm} \\ =\; & (80 \times 160) \, (x + h) \; \rm cm^{3} \end{aligned}[/tex].

In other words:

Therefore, the volume of the submerged cube could be expressed as:

[tex]\begin{aligned} & (80 \times 160) \, (x + h) \; {\rm cm^{3}} - (80 \times 160) \, h \; \rm cm^{3} \\ =\; &(80 \times 160)\, x\; {\rm cm^{3}}\end{aligned}[/tex].

On the other hand, the volume of the cube could be expressed as:

[tex](40\; \rm cm)^{3} = 64000\; \rm cm^{3}[/tex].

Equate these two expressions for the volume of the cube and solve for [tex]x[/tex], the rise in the water level in the tank:

[tex](80 \times 160)\, x = 64000[/tex].

[tex]x = 5[/tex].

In other words, the rise in the water level in this tank would be [tex]5\; \rm cm[/tex].

Answer:

A

[tex]\frac{1}{8}[/tex] = [tex]\frac{b}{4^{2} }[/tex]

b = [tex]\frac{1}{8}[/tex] × [tex]4^{2}[/tex]

b = [tex]\frac{4^{2} }{8}[/tex]

then b = [tex]\frac{c^{2} }{a}[/tex] that is ORANGE

B

-2 - v = -7

v = -7 +2

then v = k + m that is BROWN

C

[tex]\frac{14}{q}[/tex] = [tex]\frac{-7}{-4}[/tex]

q = [tex]\frac{14 * -4 }{-7}[/tex]

then q = [tex]\frac{ps}{r}[/tex] that is YELLOW

D

4m + 2(n) = 5 (n)

4m = 5 (n) - 2n

4m = 3n

m = [tex]\frac{3n}{4}[/tex]

then m =  [tex]\frac{3n}{4}[/tex] that is RED

E

-8 = [tex]\frac{x}{-5}[/tex] - 6

[tex]\frac{x}{-5}[/tex] = -8 + 6

x = -5 (-8 + 6)

then x = y( w + z ) that is LIGHT GREEN

Answer:

  3.5 inches

Step-by-step explanation:

The volume is given by the formula ...

  V = LWH

Filling in the given values, we can solve for the remaining dimension.

  26.46 in³ = (4.2 in)(W)(1.8 in)

  W = 26.46 in²/(7.56 in²) = 3.5 in

The width of the prism is 3.5 inches.

Answer:

14%

Step-by-step explanation:

Divide 770 by 5500.

You get 7/50 or 0.14.

When you convert that to a percentage, you get 14%

Based on the information given, the percentage increase will be 14%.

From the information given, it was stated that the number of foxes in national Forest has grown by 770 in the past year and that the number of foxes at the beginning of the year was 5500.

The percentage increase will be:

= 770/5500 × 100.

= 0.14 × 100

= 14%

Let's start by declaring our varibles.

x = number of lawns Mr. Brust mowed

y = total amount of money Mr. Brust made

Let's create our equation.

y = 15x + 55

For part b, we can plug 800 in for y.

800 = 15x + 55

Subtract 55 from both sides.

745 = 15x

Divide both sides by 15

50 = x. Note, I rounded the answer to the nearest integer.

For part c, we can plug 13 in for x.

y = 15(13) + 55

Simplify the right side of the equation.

y = 250

Given

[tex]A = \begin{bmatrix}-1&2\\1&4\end{bmatrix} \text{ and } B = \begin{bmatrix}1&3\\3&2\end{bmatrix} \text{ and } C = \begin{bmatrix}2&-1\\2&0\end{bmatrix}[/tex]

we have

(1)

[tex]AB = \begin{bmatrix}-1&2\\1&4\end{bmatrix}\begin{bmatrix}1&3\\3&2\end{bmatrix} \\\\ AB = \begin{bmatrix}-1\times1+2\times3 & -1\times3+2\times2 \\ 1\times1+4\times3 & 1\times3 + 4\times2\end{bmatrix} \\\\ AB = \begin{bmatrix}5&1\\13&11\end{bmatrix}[/tex]

[tex]BA = \begin{bmatrix}1&3\\3&2\end{bmatrix}\begin{bmatrix}-1&2\\1&4\end{bmatrix} \\\\ BA = \begin{bmatrix}1\times(-1)+3\times1 & 1\times2+3\times4 \\ 3\times(-1)+2\times1 & 3\times2+2\times4\end{bmatrix} \\\\ BA = \begin{bmatrix}2&14\\-1&14\end{bmatrix}[/tex]

So AB ≠ BA. This is generally true for arbitrary matrices A and B, since matrix multplication is not commutative.

(2)

[tex]2B \cdot 2C = 2^2 \cdot BC = 4 BC[/tex]

so we have 2BC = 2B•2C = 4BC if and only if BC is the zero matrix.

[tex]BC = \begin{bmatrix}1&3\\3&2\end{bmatrix}\begin{bmatrix}2&-1\\2&0\end{bmatrix} \\\\ BC = \begin{bmatrix}1\times3+3\times2 & 1\times(-1)+3\times0\\3\times3+2\times2&3\times(-1)+2\times0\end{bmatrix} \\\\ BC = \begin{bmatrix}9&-1\\13&-3\end{bmatrix}[/tex]

So 2BC ≠ 2B•2C.

(3) Yes, (AB)C = A(BC) because matrix multplication is associative. You don't need to compute this, but just to confirm this result:

[tex](AB)C = \begin{bmatrix}5&1\\13&11\end{bmatrix}\begin{bmatrix}2&-1\\2&0\end{bmatrix} \\\\ (AB)C = \begin{bmatrix}5\times3+1\times2&5\times(-1)+1\times0\\13\times3+11\times2&13\times(-1)+11\times0\end{bmatrix} \\\\ (AB)C = \begin{bmatrix}17&-5\\61&-13\end{bmatrix}[/tex]

[tex]A(BC) = \begin{bmatrix}-1&2\\1&4\end{bmatrix}\begin{bmatrix}9&-1\\13&-3\end{bmatrix} \\\\ A(BC) = \begin{bmatrix}(-1)\times9+2\times13 & (-1)\times(-1)+2\times(-3)\\1\times9+4\times13&1\times(-1) + 4\times(-3)\end{bmatrix} \\\\ A(BC) = \begin{bmatrix}17&-5\\61&-13\end{bmatrix}[/tex]

Answer:

65

Step-by-step explanation:

First lets find the area of the bottom rectangle

area of the rectangle = length × breadth

                                   = 10 × 3

                                   = 30

now lets find the area of the the above triangle

area of triangle = [tex]\frac{1}{2}[/tex] × base × height

                          =  [tex]\frac{1}{2}[/tex] × 10 × 7

                          =  [tex]\frac{1}{2}[/tex] × 70

                          = 35

now add area of rectangle + area of tringle

= 30 +35

= 65

Answer:

Step-by-step explanation:

We set up the 1st equation as

l=1.5w.

And the perimeter of a rectangle is

2w+2l=25

substitute the 1st equation into the second.

2w+2(1.5w)=25

2w+3w=25

5w=25 W=5

so l=1.5(5)=7.5
