Answer:
x = 58°
y = 74°
z = 106°
w = 42°
Step-by-step explanation:
Finding the value of unknown variables:
x + 32° = 90°
x = 90 - 32
[tex]\sf \boxed{\bf x = 58^\circ}[/tex]
x + y + 48 = 180 {Angle sum property of triangle}
58 + y + 48 = 180
y + 106 = 180
y = 180 - 106
[tex]\sf \boxed{\bf y = 74\°}[/tex]
y + z = 180 {Linear pair}
74 + z = 180
z = 180 - 74
[tex]\sf \boxed{\bf z = 106\°}[/tex]
32 +z + w = 180 {Angle sum property of triangle}
32 + 106 +w = 180
138 + w = 180
w = 180 - 138
[tex]\sf \boxed{\bf w = 42\°}[/tex]

13 What value of x makes the equation modeled below true? PHONE 1 1 1 A x = 1 B x = -1 C x = 7 D x = -5 I
Answers
SOLUTION
Step 1 : We need to recognize the value of x in 5 places means 5 x
and the value of 1 in 6 times means 6,
so we have that: 5 x + 6 = 1 .
Step 2 : We need the linear equation: 5 x + 6 = 1
collecting like terms, we have that:
5 x = 1 - 6
5 x = - 5
Divide both sides by 5 , we have that:
x = - 1
CONCLUSION : The value of x = -1 ( OPTION B )

What is the sign of 3.456 + \left(-3.456\right)3.456+(−3.456)
A. Positive
B. Negative
C. Neither positive nor negative—the sum is zero.
Answers
The sign of 3.456+(-3.456) is neither positive nor negative—the sum is zero.
We are asked to find the sign of 3.456+(-3.456)
This expression can be simply written as 3.456 - 3.456 because of the identity we have, x+(-y) = x-y
Now if same quantities are subtracted, we get zero only.
Also zero is neither positive nor negative.
Hence there is no sign for 3.456+(-3.456).
Also 3.456+(-3.456) = 0.

Vinny is serving punch to guests at a party. He has $\frac{3}{4}$ of a gallon of punch, and he pours $\frac{5}{64}$ of a gallon into each guest's cup, filling each to the top. At the most, how many guests' cups can he fill to the top?
Answers
In serving punch to guests at the party, Vinny can fill 9 guests' cups to the top based on this unit rate.
What is a unit rate?The unit rate is the ratio of a variable to another.
The whole number here is the total gallons of punch available to serve the guests.
The unit rate is the volume that each guest's cup can hold or contain.
This implies that the ratio is 5/64: 3/4
The total number of gallons of punch = 3/4 or 0.75 gallons.
The volume or capacity of each guest's cup = 5/64 gallons or 0.078125.
The number of guests' cups to fill to the brim = 9.6 cups (0.75/0.078125)
= 9 guests' cups.
Thus, Vinny can fill 9 guests' cups to the brim, using the given ratio or unit rate.

arif's backyard is 22 by 32 meters. he wants to put a flower garden in the middle of the backyard, leaving a strip of grass of uniform width around the flower garden. to be happy, arif must have 288 m^2 of grass. under these conditions what will the length and width of the garden be?
Answers
The dimension of the flower garden, which located in the middle of the backyard surrounded by a strip of grass, is 26 m length and 16 m width.
The situation can be depicted on the attached picture.
We need to translate the word problem into algebraic expressions.
Let x be the width of the grass strip.
Let A be the area of the grass strip.
Then,
A = 2 . 22x + 2 . (32 - 2x)x
288 = 2 . 22x + 2 . (32 - 2x)x (divide by 2)
144 = 22x + x(32 - 2x) (divide by 2)
72 = 11x + x(16 - x)
72 = 27x - x²
x² - 27x + 72 = 0
This is a quadratic equation. One of the methods to solve a quadratic equation is by factorization.
Factorize the left side:
(x - 3) (x - 24) = 0
x = 3 or x = 24
The length of the flower garden = 32 - 2x
The width of the flower garden = 22 - 2x
Substitute x = 3:
The length of the flower garden = 32 - 2 . 3 = 32 - 6 = 26 m
The width of the flower garden = 22 - 2 . 3 = 16 m
Note that if we substitute x = 24, it will results in negative values while the dimension is always positive.

how long would it take to drive 1km at a speed of 1.71km/h (with working)
Answers
It would take 35 minutes to drive 1 km at a speed of 1.71 km/h.
How do distance and speed compare?Speed is the ratio of distance traveled in a given time. Speed is given by distance/time.
The time can be computed by dividing distance by speed.
This implies that time is the quotient of distance and speed.
The total distance drove = 1 km
The driving speed = 1.71 km/h
Time = Distance/Speed
= 1/1.71
= 0.58 hours

How to find the percentage of members that voted?The art club had an election to select a president. 42 out of the 60 members of the art club voted in the election.
Therefore, the percentage of the members that voted can be calculated as follows;
percentage that voted = number of people that voted / total number members × 100
Therefore,
number of people that voted = 42

Brown bears attempt to catch salmon. during the day, 20% of the attempts are successful. during the night, 36% of attempts are successful. a bear tries to catch 40 fish during the day and makes 50 attempts at night. use probability to estimate the number of fish the bear caught.
Answers
The probability for the number of fish the bear caught is 0.289
Given,
Number of fish the bear tries to catch during day = 40
Number of attempts made by the bear at night = 50
Percentage of successful attempts during day = 20%
Percentage of successful attempts at night = 36%
Number of fish the bear caught during day = 40 × (20/100) = 4 × 2 = 8 fish
Number of fish the bear caught at night = 50 × (36/100) = 36/2 = 18 fish
Total number of fish the bear caught = 8 + 18 = 26 fish
Now,
Probability for the number of fish the bear caught:
Probability = Number of fish caught / Total attempts
Probability = 26 / (40 + 50)
Probability = 26 / 90
Probability = 0.289
Therefore,
The probability for the number of fish the bear caught is 0.289

Larry plants to invest 275,000 for 30 years at an anticipated rate of 6% per annum compounded yearly what is the approximate difference in his ending balance of the actual rate is 5% instead of six
Answers
Answer:
$390,000
Explanation
To do this, we will use the compound interest formula;
A = P(1+r)^t
P = 275000
rate r = 6%
Time t = 30years
Substitute
A = 275000(1+0.06)^30
A = 275000(1.06)^30
A = 275000(5.7435)
A = 1,579,460.07
For the rate of 5%
A = 275000(1+0.05)^30
A = 275000(1.05)^30
A = 275000(4.3219)
A = 1,188,534.15
Takeing their difference;
Difference = 1,579,460.07-1,188,534.15
Difference =390,925.92
Hence the approximate difference in his ending balance of the actual rate is 5% instead of six is about $390,000

What are the coordinates of the point on the directed line segment from (3,−3) to (7,5) that partitions the segment into a ratio of 5 to 3
Answers
The coordinates along the directed line segment is (37/7, 11/7)
How to find the coordinates of the point?The points are given as:
A = (3, -3)
B = (7, 5)
The ratio on the segment can be represented as;
m : n = 4 : 3
So, we have the coordinates of the point that lies along the directed line segment to be
Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)
So, we have:
Point = 1/(4 + 3) * (4 * 7 + 3 * 3, 4 * 5 + 3 * -3)
Evaluate
Point = 1/7 * (37, 11)
Evaluate the products
Point = (37/7, 11/7)
Hence, the coordinates of the point is (37/7, 11/7)

The finish line is 253 m away. You begin to run from rest. You must reach a velocity of 53.2 m/s or you will explode. What must your acceleration be?
Answers
The acceleration require for the body to not explode will be 0.2941[tex] m/s^2 [/tex]
The finish line as given is 253m away so that distance to be covered will be 253m.
Also we had started to run from rest so that initial velocity will be 0m/s.
We should take care that we could not explode and this is possible only if we reach to the velocity of 53.2m/s. So our final velocity will be 53.2m/s.
Now average velocity will be the sum of initial velocity and final velocity divided by 2.
∴ Average velocity = (initial velocity + final velocity) / 2.
∴ Average velocity = (0 + 53.2) / 2 = 53.2 / 2 = 26.6m/s
As we know that average velocity will give us an average time of the run by formula average speed = distance / average time.
∴ Average time = distance / average speed
∴ Average time = 253 / 26.6 = 9.51s.
Now as we know by the formula to calculate acceleration we need the average velocity, average time and we have both of them.
∴ Acceleration = [tex] \frac{average\ velocity}{(average\ time)^2}[/tex]
∴ Acceleration = [tex] \frac{26.6}{(9.51)^2}[/tex]

The length of the rectangle is 10, the width is 2.5 and the perimeter is 25
Let the width of the rectangle be x
The length of rectangle = 2x + 5
The overall length of the outline determines a rectangle's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Since the opposite sides of a rectangle are always equal, we must determine the length and width of the rectangle in order to determine its perimeter.
Perimeter = 10 times of width
