joan needs $60 for a class trip. She has $32. She can earn $4 an hour mowing lawns. How many hours must Joan to have the money she needs?
Joan has 32$. And makes 4$ every hour of mowing lawns.
60-32=28.
So what we will do to solve this problem is multiply 7 by 4.
7x4= 28.
32+28=60.
This means that Joan needs to work 7 hours in total to earn $28.
Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units. The larger triangle's longest side is 52 units. What is the perimeter of the larger triangle?
Answer:
117 units
Step-by-step explanation:
if you use the ratio of the two longest sides then you can find all side lengths
[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{10}[/tex]; x = half of 52, or 26
[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{15}[/tex]; 20x = 52 · 15
20x = 780
x = 39
add to get perimeter: 52 + 26 + 39 = 117 units
Perimeter of the larger triangle is 117 units
Given
Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units.
When the triangles are similar then the sides are in proportion
the longest side of the smaller triangle is 20 units
The larger triangle's longest side is 52 units.
Lets find out the unknown sides of largest triangle
Let x and y be the unknown sides . Make a proportion and solve for x and y
[tex]\frac{52}{20}=\frac{x}{10} \\x=\frac{52}{20} \codt 10\\x=26\\\\\\\frac{52}{20}=\frac{y}{15}\\y=\frac{52}{20} \codt 15\\y=39[/tex]
The unknown sides of largest triangle is 26 and 39 units
To find out the perimeter add all the sides of largest triangle
Perimeter =[tex]26+39+52=117[/tex]
Perimeter of the larger triangle is 117 units

A full glass of water can hold 1/6 of a bottle
How many glasses of water can be filled with 3 1/2 of water
Answer:
21
Step-by-step explanation:
Well you basically divide 3 and 1/2 by 1/6 which you would you have to simplify the 3 and 1/2 which is 7/2 and switch the denominator and numerator of the 1/6 which would be 6/1 and after you multiply(7/2 x 6/1=42/2) it would be 42/2 which you would have to simplify by dividing 42 and 2 which is 21. There you go I hope this helps.
Answer:
21.
Step-by-step explanation:
That would be 3 1/2 divided by 1/6.
= 7/2 / 1/6
= 7/2 * 6
= 42/2
= 21 glasses.

A 14-meter ladder leans against a building forming a 30° angle with the building. Exactly how
high is the ladder on the building in meters? Round to the nearest hundredth (2 digits after the
decimal).
Answer: 12.12 m
Step-by-step explanation:
Given
length of ladder L=14 m
the ladder makes an angle of [tex]\theta=30^{\circ}[/tex] with the building
With the help of a diagram, we can write
[tex]\cos \theta=\frac{\text{h}}{\text{L}}[/tex]
[tex]\cos 30^{\circ}=\frac{h}{14}[/tex]
[tex]h=14\cos 30^{\circ}[/tex]
[tex]h=12.12\ m[/tex]
From a point on a cliff 75 feet above water level, an observer can see a shipThe angle of depression to the ship is d^ How far is the ship from the base of the to the nearest foot?
Answer:
52feet
Step-by-step explanation:
The set up will be a right angle
Let the angle of depression be 30°
The height above the sea level will be the opposite
The distance of the ship from the base is x (adjacent)
Using TOA
Tan theta = opposite/adjacent
Tan 30 = 30/x
x = 30/tan 30
x = 30/0.5774
x = 51.96
x ≈ 52 feet to the nearest foot
Find x
Tan(x) = 1 - (Sqroot2)
Answer:
16.32495 degrees
Step-by-step explanation:
1- sqrt/2 = (2-sqrt2)/2
x = arctan((2-sqrt2)/2) = 16.32495 degrees
please help me with this and pls don't answer if you don't know it.
Answer:
See below.
Step-by-step explanation:
The 3 marked angles add up to 360 degrees.
5x + 12 + 10x - 37 + 9x + 1 = 360
24x - 24 = 360
24x = 384
x = 384/24 = 16
The large angle at C = 10(16) - 37
= 160 - 37 = 123 degrees.
So m <BCA = 180 - 123
= 57 degrees (adjacent angles add up to 180).
Nadia thinks of a number.
She finds the square root and then divides by 5.
Her answer is 20.
What number is she thinking of?
let the num be a
/a÷5=20
/a=20×5
/a =100
square root of 100 is 10
so the number is 10
The number that she have to think of should be considered as the 10 when her answer is 20.
Calculation of the number:Since here we assume the number be a
And, now she have to determine the square root and then divide it by 5
So, it can be like
[tex]a\div 5=20\\\\a=20\times 5[/tex]
a =100
Now the square root of 100 should be 10
hence, a = 10
Therefore, The number that she have to think of should be considered as the 10 when her answer is 20.

3 more than 2 times a number is equal to that number plus 4. What is the number?
Answer:
number is 1
Step-by-step explanation:
let the number be n , then 2 times the number is 2n and 3 more than this is
2n + 3 , so
2n + 3 = n + 4 ( subtract n from both sides )
n + 3 = 4 ( subtract 3 from both sides )
n = 1
That is the number is 1
The required number is 1 which represents "3 more than 2 times a number is equal to that number plus 4"
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
Let the required number would be x.
According to the given question, translate the phrase into an algebraic equation:
3 + 2x = x + 4
Subtracting x from both sides gives:
3 + 2x - x = x + 4 - x
Simplifying the left side gives:
3 + x = 4
Subtracting 3 from both sides gives:
3 + x - 3 = 4 - 3
Simplifying the left side gives:
x = 1
Therefore, the required number would be 1.

m = rise/run = -1/2 . . . . slope in simplest form
__
Additional comments
It usually works best if you can identify points on the graph where the line crosses grid intersections. Then the number of squares in each direction can be counted easily. If you work with two grid intersections that are closest together, then the ratio of rise to run will already be in reduced form.
On this graph, there are other grid crossing points that are 4, 6, 8 units to the right or left of the one where we started. You need to remember that "run" is positive in the "right" direction, and "rise" is positive in the "up" direction.
We have shown the "rise" and "run" lines above the graphed line. They can also be shown below the graphed line.
Here, the grid squares are 1 unit in each direction. You need to pay attention to the scale, because some graphs have different numbering vertically than horizontally. The values for "rise" and "run" need to be figured using the appropriate scale.

Find all x-intercepts of the following function. Write your answer or answers as coordinate points. Be sure to select the appropriate number of x-intercepts.
Answer:
(- 3, 0 ), (4, 0 )
Step-by-step explanation:
To find the x- intercepts let f(x) = 0
[tex]\frac{x^2-x-12}{5x^2+ 4x}[/tex] = 0
The denominator cannot equal zero as this would make f(x) undefined.
Equate the numerator to zero and solve for x
x² - x - 12 = 0 ← in standard form
(x - 4)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
x- intercepts are (- 3, 0 ) and (4, 0 )

Mike, a Salvation Army bell ringer, has 20% as many quarters as nickels in his cup. If Mike has $6.00 in quarters and nickels, how many nickels does he have?
If If Mike has $6.00 in quarters and nickels, then the number of nickels Make have are 60.
Let's assume that the number of nickels in Mike's cup is "N." Since Mike has 20% as many quarters as nickels, the number of quarters can be expressed as 0.20N.
Now, we know that the total value of the quarters and nickels is $6.00. The value of each nickel is $0.05, and the value of each quarter is $0.25.
So, we can set up the equation:
0.05N + 0.25(0.20N) = 6.00
Now, let's solve for N:
0.05N + 0.05N = 6.00
0.10N = 6.00
N = 6.00 / 0.10
N = 60
So, Mike has 60 nickels in his cup.
