Answer:
x=-2
Step-by-step explanation:
1. Convert base
(1/64) to (4^-3)
2.Apply exponent rule
4^-3(2x+10)
3. 4x-10=-3(2x+10)
4.Expand
4x-10=-6x-30
4x-10+10=-6x-30+10 (add 10 to both sides)
4x=-6x-20 (simplify)
4x+6x=-6x-20+6x (add 6 to both sides)
5. 10x=-20 (divide both side by 10)
6. Then you get x= -2.

m= -2
Step-by-step explanation:
The solution is m = -2
Step-by-step explanation:
The given rational equation is
We'll simplify the left hand side first.
The LCD is (m+4)(4-m)
Hence, multiply and divide the first term by 4-m and second by m +4
Use the difference of squares rule
We can now add the numerator
On simplifying, we get
Add the like terms
Multiply and divide left hand side by -1
We can cancel the denominator
Divide both sides by 8
The solution is m = -2
Joshua has a ladder that is 15 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 14.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 70°. Will the ladder be safe at this height? Show your work and draw a diagram to support your answer.
Joshua's 15 ft ladder, if leaned against the wall to reach a height of 14.8 ft, would be at an unsafe angle less than 70° and thus, is not safe to use in this manner.
Explanation:The student has asked whether Joshua's ladder, which is 15 feet long and is supposed to lean against a wall with the top at 14.8 feet above the ground, will be safe with an angle no greater than 70°. To determine this, we can use the trigonometric function cosine, which relates the adjacent side (the height at which the top of the ladder reaches the wall) to the hypotenuse (the length of the ladder) in a right-angled triangle. The cosine of the maximum safe angle (70°) should therefore be equal to or greater than the ratio of the height of the ladder against the wall (14.8 feet) to the length of the ladder (15 feet).
We calculate the cosine of 70°: cos(70°) ≈ 0.342. Then we calculate the ratio 14.8/15 which equals 0.9867. Since 0.9867 is much greater than 0.342, it means the ladder will form an angle that is less than 70°, which is not within the safe range as per Joshua's requirement.
Therefore, it is not safe for Joshua to lean the ladder in this manner because the angle formed will be steeper than the maximum safe angle of 70°, which may result in the ladder slipping.

Other 60 70
A. 0.171
B. 0.467
C. 0.269
D. 0.389
Answer:D. 0.039
Step-by-step explanation:
The probability that a student is taking a humanities class, given the student is male, is 0.389 option (D) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
We have the total number of male students = 70+50+60 = 180
So, the total number of outcomes = 180
Total number of male students who take humanities class = 70
Now, the probability = 70/180 = 0.388 ≈ 0.389
Thus, the probability that a student is taking a humanities class, given the student is male, is 0.389 option (D) is correct.

Find the shaded area.
Answer:
13.73
Step-by-step explanation:
Answer: 13.7345175425633 square feet
The rounding instructions are cut off, so it's not clear how you want to round this.
========================================================
Explanation:
The area of the square is 8*8 = 64 square feet.
The two unshaded semicircles combine to form a full circle of radius 4 ft. This circle has an area of A = pi*r^2 = pi*4^2 = 16pi square feet.
The shaded area is the result of taking the circle area away from the larger square area
shaded area = (area of large square) - (area of two semicircles)
shaded area = (area of large square) - (area of circle with radius 4)
shaded area = 64 - 16pi = exact value
shaded area = 13.7345175425633 = approximate value
Everfi module 3 budgeting for wants
Answer:
The budget breakdown is as follows;
Savings = $354.00
Clothing = $88.50
Entertainment = $88.50
Charitable giving = $44.00
Amount left = $0.00
Step-by-step explanation:
In the budgeting process, needs and the recurring expenditures are first addressed followed by savings which consists of emergency funds that can be used on unexpected expenses and reduces the tendency for borrowing.
Therefore, the appropriate amount for savings in a budget is found from the 50-20-30 rule.
That is the after tax income is weighted to 100 from which;
50% is expended on needs and recurring expenditures
20% of the after tax income should be kept as savings and
30% can be spent on wants
Based on the above rule, with a take home pay of $1,770 we have;
Amount meant for savings = 20% of $1,770 = $354.00
Since $354.00 is to be kept as savings we have;
Amount on Clothing + Entertainment + Charitable = $575 - $374 = $221
The amount on clothing should be 5% of the monthly income, which gives;
5% of $1,770 = 0.05× $1,770 = $88.5
Therefore amount on entertainment which should also be 5% =$88.5
Hence the amount for charitable giving = $221 - $88.5 - $88.5 = $44.00
Hence the budget breakdown should be;
Savings = $354.00
Clothing = $88.50
Entertainment = $88.50
Charitable giving = $44.00
Amount left = $0.00.
Budget represents financial plan over a period of time.
The money would be allocated as follows:
[tex]Savings = \$354[/tex][tex]Clothing = \$88.5[/tex][tex]Entertainment = \$88.5[/tex][tex]Charitable\ Giving = \$44[/tex]The total home pay is given as:
[tex]Total = \$1770[/tex]
In budget, 20% are always allocated to savings.
So, we have:
[tex]Savings = 20\% \times Total[/tex]
[tex]Savings = 20\% \times \$1770[/tex]
[tex]Savings = \$354[/tex]
The amount to spend is given as:
[tex]Spend = \$575[/tex]
The amount left, after savings is:
[tex]Amount = Spend - Savings[/tex]
[tex]Amount = \$575 - \$354[/tex]
[tex]Amount = \$221[/tex]
The $221 would be spent on entertainments, clothing and charitable givings.
In budgets, 5% of total home pay is always allocated for entertainments and for clothing.
So, we have:
[tex]Clothing = 5\% \times Total[/tex]
[tex]Clothing = 5\% \times \$1770[/tex]
[tex]Clothing = \$88.5[/tex]
Also
[tex]Entertainment = Clothing = \$88.5[/tex]
The amount on charitable giving is:
[tex]Giving = Amount\ Left - Entertainment - Clothing[/tex]
[tex]Giving = \$221 - \$88.5 - \$88.5[/tex]
[tex]Giving = \$44[/tex]
Hence, the money would be allocated as follows:
[tex]Savings = \$354[/tex]
[tex]Clothing = \$88.5[/tex]
[tex]Entertainment = \$88.5[/tex]
[tex]Charitable\ Giving = \$44[/tex]

A stained glass window has an area of 900 square inches.
a. One window design is made of rectangular stained glass pieces that are 5 inches by 3 inches. How many stained glass pieces are used in the window?
b. Another window design is made of square stained glass pieces that are 6 inches by 6 inches. How many stained glass pieces are used in the window?
Answer:
a. 60
b. 25
Step-by-step explanation:
Given that the stained glass window has an area of 900 square inches and this is made of smaller rectangular stained glass pieces, the number of smaller rectangular stained glass pieces used will be equal to the total area (900 square inches) to the area of the smaller rectangular piece.
The area A of the rectangular piece of length l and width w may be stated as
A = l * w
Hence given that
- One window design is made of rectangular stained glass pieces that are 5 inches by 3 inches, number of stained glass pieces are used in the window
= 900/(3 * 5)
= 60
- Another window design is made of square stained glass pieces that are 6 inches by 6 inches, number of stained glass pieces are used in the window
= 900/(6 * 6)
= 25
Answer:
a. 60 pieces
b. 25 pieces
Step-by-step explanation:
Hi, to answer this question we have to calculate the area of each rectangular stained glass.
Area = width x length
a.
5 x 3 = 15 square inches
Now we have to divide the area of the window by the area of each stained glass.
900/ 15 = 60 pieces
Same process for b
b.
6x6 = 36 square inches
900/36= 25 pieces

What is the converse of a theorem?
A. A statement that is given
B. A statement that cannot be proven
C. A statement that is proved by two different theorems
D. A statement formed by transposing what is to be proved by a theorem and what is given
The converse of a theorem is created by reversing the hypothesis and the conclusion of the theorem's statement. The correct multiple-choice answer is 'D. A statement formed by transposing what is to be proved by a theorem and what is given.'
The converse of a theorem is a logical statement where the elements of the theorem's statement are switched. If you have a theorem that states "If A, then B," the converse of that theorem would be "If B, then A." This essentially transposes the hypothesis and the conclusion. In the context of the multiple-choice options provided, the correct answer is D.
A statement formed by transposing what is to be proved by a theorem and what is given. It's important to note that even though a theorem is proven true, its converse is not necessarily true and must be proven separately if it is to be accepted as true.

1. Find the equation of the line that has a slope of 10 and a y-intercept of 15.
Use form y=mx+b
Answer:
y = 10x + 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = 10 and b = 15, thus
y = 10x + 15
A rectangle has length x and width y.
The perimeter of the rectangle is 32.
Part A
Write an equation that represents the relationship between x and y described above.
Answer:
2x + 2y = 32
Step-by-step explanation:
2 sides of each rectangle are always equal to each other, and there's 2 pairs of that, top&bottom and side&side
The perimeter is all the sides added together, so it's x + x +y +y, which can be written as 2x + 2y
The relationship between the length (x) and width (y) of a rectangle with a perimeter of 32 can be represented by the equation 2*(x+y)=32, derived from the formula for the perimeter of a rectangle.
Explanation:The subject of this question is mathematics, specifically relating to geometry and algebra. To express the relationship between the length, x, and width, y, of a rectangle with a perimeter of 32, you can form an equation based on the formula for the perimeter of a rectangle.
The formula for the perimeter of a rectangle is 2*(length+width). In this case, the length is x and the width is y, and we know that the total perimeter is 32. This can be expressed in the following equation: 2*(x+y) = 32.

Luna packed two chocolate bars for the trip.One s’more uses 1/12 of a bar. How should we complete model
The days will the chocolate last is A) More than 12 days . Therefore A) More than 12 days is correct .
One chocolate bar lasts for 12 days because 1 / (1/12) = 12
Two chocolate bars last for 24 days because 12 * 2 = 24
So, even if Luna has one s'more a day, the chocolate will last for more than 12 days.
The other options are not as likely:
Option (B) is less likely because two chocolate bars would still last for more than a day, even if she had one s'more a day.
Option (C) is possible, but it's less likely than option (A) because two chocolate bars would provide more than 12 s'mores worth of chocolate.
Therefore, the answer is A) More than 12 days.
