Answer:
The solution is -5 or 11
Step-by-step explanation:
We are given the equation;
[tex]4(3-x)^\frac{4}{3}-5=59[/tex]
We are supposed to solve the equation;
Taking 5 to the other side;
[tex]4(3-x)^\frac{4}{3}=59+5[/tex]
[tex]4(3-x)^\frac{4}{3}=64[/tex]
Dividing both sides by 4
[tex](3-x)^\frac{4}{3}=\frac{64}{4}[/tex]
[tex](3-x)^\frac{4}{3}=16[/tex]
We can cube both sides;
[tex]((3-x)^\frac{4}{3})^3=16^3[/tex]
[tex](3-x)^4=4096[/tex]
Then we can get the fourth root on both sides of the equation;
[tex]\sqrt[4]{ (3-x)^4} =\sqrt[4]{4096}[/tex]
We get;
[tex]3-x=+8 or -8[/tex]
Solving for x
[tex]3-x=8 and 3-x=-8[/tex]
Therefore;
[tex]x=-5 or 11[/tex]
Therefore, the solution is -5 or 11

7+ 2x divided by 5= 13
Answers
Answer:
[tex]x=29[/tex]
Step-by-step explanation:
Given equation :
[tex]\frac{(7+2x)}{5} =13[/tex]
Making the terms of 'x' to one side and constants to the other.
[tex](7+2x)=13*5[/tex]
[tex]7+2x=65[/tex]
[tex]2x=65-7[/tex]
[tex]2x=58[/tex]
[tex]x=\frac{58}{2}[/tex]
[tex]x=29[/tex]
So, the value of 'x' is 29.
Answer:
x = 29
Explanation:
7 + 2x / 5 = 13
Multiply both sides by 5
7 + 2x / 5 = 13 · (5) = (13) · (5)
7 + 2x = 65
Simplify both sides of the equation
2x + 7 = 65
Subtract 7 from both sides
2x + 7 − 7 = 65 − 7
2x = 58
Divide both sides by 2
2x / 2 = 58 / 2
x = 29
If it takes 930 kg of food to feed a pair of elephants for 3 days how much food would u need to feed them for a week?
Answers
Steps:
Divide 930 by 3 to see how much food per day
Then multiply by 7 to see how much food needed for a week
Answer:
2170 kg
Step-by-step explanation:
since there are 7 days in a week first you calculate the days
930 plus 930 equals 1860 which can feed a pair of elephants for 6 days
then since in one day it takes 310 kg then add 1860 plus 310
and then you get 2170
so, you need 2170 kg of food to feed a pair of elephants in a week

Calculate the area of the regular pentagon below:
Answers
Answer:
1064.8 in^2
Step-by-step explanation:
12.1 x 17. 6 / 2 to find one half of a triangle will equal 106.48
there are 10 triangle therefore 106.48 x 10 = 1064.8
Answer:
532.4 in²
Step-by-step explanation:
The area (A) of the regular pentagon is calculated as
A = 0.5 × perimeter × apothem
Perimeter = 5 × 17.6 = 88 in
The apothem is the segment from the centre to the midpoint of one of the sides.
Here the apothem = 12.1 in, thus
A = 0.5 × 88 × 12.1 = 44 × 12.1 = 532.4 in²

the framed portrait in terms of w?
A. 1.5W2 + 5W + 4
B. 1.5w2 + 8w + 8
C. 1.5w2 + 8.5w + 16
D. 1.5w2 + 10w + 16
Answers
Answer:
The correct answer is A. 1.5w² + 5w + 4
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Height of the portrait = 1.5 times its width in inches
Frame = 2 inches all along its perimeter
2. What is an expression for the area of the framed portrait in terms of w?
Let's recall that the area of a rectangle is length or height * width.
A = height * width
Now, we can replace in terms of w:
A = 1.5w * w
But we need to add the 2 inches of the frame, this way:
A = (1.5w + 2) * (w + 2)
A = 1.5w² + 2w + 3w + 4
A = 1.5w² + 5w + 4
The correct answer is A. 1.5w² + 5w + 4
Final answer:
The expression for the area of the framed portrait in terms of w is 1.5w^2 + 8w + 8.
Explanation:
To find the expression for the area of the framed portrait, we need to consider the dimensions of both the portrait and the frame. Let's assume the width of the portrait is w inches. According to the given information, the height of the portrait without the frame is 1.5 times the width, so the height is 1.5w inches.
To calculate the dimensions of the framed portrait, we need to add 2 inches to the width and height for the frame. The width of the framed portrait is w + 2 inches, and the height is 1.5w + 2 inches.
The area of the framed portrait is equal to the product of its width and height. Therefore, the expression for the area, in terms of w, is (w + 2) * (1.5w + 2). When we simplify this expression, we get 1.5w2 + 8w + 8.

Answers
Answer:
Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric, as can be observed from the stem and leaf frequency plot.
Step-by-step explanation:
CALCULATIONS FOR BAKERY A
Considering the data for Bakery A
45 52 51 48 57 30 55 46
Calculating Mean for Bakery A
[tex]Mean=\frac{Sum\:of\:terms}{Number\:of\:terms}[/tex]
Sum of terms = 45 + 52 + 51 + 48 + 57 + 30 + 55 + 46 = 384
Number of terms = 8
As
[tex]Mean=\frac{Sum\:of\:terms}{Number\:of\:terms}[/tex]
[tex]Mean=\frac{302}{8}[/tex]
[tex]Mean=48[/tex]
Calculating Median for Bakery A
As the median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
As the data for Bakery A is
45 52 51 48 57 30 55 46
Ordering the data from least to greatest, we get:
30 45 46 48 51 52 55 57
As you can see, we do not have just one middle number but we have a pair of middle numbers, so the median is the average of these two numbers:
[tex]Median=\frac{\left(48+51\right)}{2}=\frac{99}{2}=49.5[/tex]
Getting a Plot and Leaf Plot for Bakery A
Plot and leaf plot is generally a unique table-like diagram which displays the frequency distribution of a data set. Plot and leaf plot is a visual aid that supports us in recognizing frequency classes and the center of the distribution where most of the data gets clustered around.Data for Bakery A in ascending order

Sum of terms = 48 + 42 + 11 + 45 + 57 + 10 + 43 + 46 = 302
Number of terms = 8
[tex]Mean=\frac{302}{8}=37.75[/tex]
Calculating Median for Bakery B

The angle measure of m∠ACB (x°) is 39°.
Step-by-step explanation:
Let us name the joining points as ABC and ABC forms triangle with extended lines. (refer the image)
We have to find the value of m∠ACB = x°.
the given data,
m∠A=68°.
m∠B =107°.
To find m∠CAB,
Let us consider that AB is a line traversed by a line C intersecting at A. (refer diagram)
Using the theorem of corresponding angles theorem, when a line intersects another line, then the angles opposite each other is equal to each other.
m∠A=m∠CAB.
m∠CAB =68°.
To find m∠ABC,
Let us consider AB is a line.(refer diagram)
Using the straight line proof, the total of angles in a straight line is 180°.
Thus m∠ABC+m∠B=180°.
m∠ABC+107°=180°.
m∠ABC=180°-107°.
m∠ABC=73°.
Finally we have to find the value of x° that is m∠ACB.
Using the interior angles proof, the sum of interior angles of triangle is 180°.
⇒m∠ABC+m∠CAB+m∠ACB=180°.
73°+68°+m∠ACB=180°.
141°+m∠ACB=180°..
m∠ACB=180°-141°.
m∠ACB=39°.
Thus the angle measure of m∠ACB (x°) is 39°.

Answers
Answer:
The price for one hat was $5 and the price for one scarf was $4
Step-by-step explanation:
Let
x ----> the price for one scarf in dollars
y ----> the price for one hat in dollars
we know that
Dakota bought 2 scarves and 1 hat for $13
so
[tex]2x+y=13[/tex] ----> equation A
Kristina bought 1 scarf and two hats for $14
so
[tex]x+2y=14[/tex] ----> equation B
Solve the system by elimination
Multiply by -2 both sides equation B
[tex]-2(x+2y)=-2(14)[/tex]
[tex]-2x-4y=-28[/tex] ----> equation C
Adds equation A and equation C
[tex]2x+y=13\\-2x-4y=-28\\---------\\y-4y=13-28\\-3y=-15\\y=5[/tex]
Find the value of x
substitute the value of y in any equation
equation B
[tex]x+2(5)=14\\x=14-10\\x=4[/tex]

A building in a city has a rectangle base. The length of the base measures 70 feet less than three times the width. The perimeter of this base is 900 feet. What are the dimensions of the base?
Answers
Answer:
Width 130 ft and
Length 320 ft
Step-by-step explanation:
We are given;
Length of the rectangular base is 70 ft less than three times the width;Perimeter of the rectangular base is 900 ftWe are required to determine the dimensions of the rectangular base;
Assuming the width of the rectangular base is x ft
Then length will be (3x - 70) ft
But;
Perimeter = 2L + 2W
Thus;
900 ft = 2(3x-70) + 2(x)
900 ft = 6x -140 +2x
1040 = 8x
x = 130
Thus;
Width = 130 ft
Length = 3x -70 = 320 ft
Hence the dimensions of the rectangular base are width 130 ft and length 320 ft
The sum of two numbers is zero. When 13 times the smaller number is added to 8 times the larger, the result is 2. Find the two numbers.
Answers
Answer:
x = (2/5); y = (-2/5)
Step-by-step explanation:
x + y = 0
13x + 8y = 2
Multiply so the "x" variables are opposite with the same absolute value.
(-13) x + y = 0 (-13) ⇒ -13x - 13y = 0
(1) 13x + 8y = 2 (1) ⇒ 13x + 8y = 2
Add the two equations.
(13x - 13x) + (8y - 13y) = (2 - 0)
-5y = 2
Divide both sides by -5
y = [tex]-\frac{2}{5}[/tex]
Plug the value of "y" into either equations.
x + [tex](-\frac{2}{5})[/tex] = 0
Add [tex]\frac{2}{5}[/tex] to both sides.
x = [tex]\frac{2}{5}[/tex]

Perpendicular to 3y=x-4 and passes through the point (-2,1)
Answers
Answer:
The equation is [tex]y=-3x-5[/tex]
Step-by-step explanation:
We are given;
The equation of a line 3y = x-4 A point (-2,1)Assuming the question requires we determine the equation of a line perpendicular to the given line and passing through the point given.
Step 1: Determine the slope of the given line
To determine the slope from an equation requires we write the equation in the form, y = mx + c, where m will be the gradient.
In this case;
[tex]3y = x - 4\\ y = \frac{1}{3}x-\frac{4}{3}[/tex]
Therefore, the slope is [tex]\frac{1}{3}[/tex]
Step 3: Determine the slope of the line in question
We know that the product of the slope of two perpendicular line is -1
That is;
m₁ × m₂=-1
Thus;
1/3 × m₂ -1
Hence; m₂ = -3
Step 3: Determine the equation of the line in question;
We have its slope, m₂ = -3
A point (-2, 1)
Taking another point (x,y)
Thus;
[tex]\frac{y-1}{x--2}=-3\\y-1 =-3(x+2)\\y-1 = -3x-6\\y=-3x-5[/tex]
Therefore, the required equation is [tex]y=-3x-5[/tex]
The equation of the line perpendicular to the line and passing through the point is y = -3x - 5
Equation of a lineGiven the equation 3y = x - 4
Find the slope of the line
y = 1/3 x - 4/3
The slope of the line is 1/3 and the slope of the line perpendicular is -3
Substitute the point (-2, 1) and the slope into equation
y - y1 = m(x-x1)
y - 1 = -3(x+2)
y - 1 = -3x - 6
y = -3x - 5
Hence the equation of the line perpendicular to the line and passing through the point is y = -3x - 5
