Answer:
17
Step-by-step explanation:
Hay dos cursos que se ofrecen en la escuela y se representan como fracciones.
Cursos corresponden a la enseñanza media = 8/25
Cursos de enseñanza básica =?
Sea el número total de cursos = 1
Cursos de enseñanza básica = 1 - 8/25
= 17/25
Dado que ambos cursos están en forma de fracciones, podemos convertirlos en razones
Relación de cursos corresponden a la enseñanza media a cursos de enseñanza básica
= 8:17
Donde el número total de cursos ofrecidos = 8 + 17 = 25
Por lo tanto, el número que representa los cursos de enseñanza básica = 17.
what describes the first factor in scientific notation
Answer:
mantissa
Step-by-step explanation:
The word "mantissa" is used to describe the portion of the number that represents the significant digits in scientific notation.
__
The term also refers to the fractional portion of a logarithm. Of course, that fractional portion also represents the significant digits of the number. The integer portion of the logarithm is the power of 10 that multiplies the significant digits.

Rewrite the equation below using ONLY the symmetric property of equality:2x + 5 = 3x -7
Answer:
12 = x
Step-by-step explanation:
Symmetry here would involve subtracting the same quantity from both sides of the equation.
Starting with 2x + 5 = 3x -7,
subtract 2x from both sides. This yields
5 = x - 7
Adding 7 to both sides yields
12 = x
Malcom has $638.54 in his checking account he must maintain a $500 balance to avoid a fee he wrote a check for $159.50 today write and solve an inequality to solve for the least amount of money he needs to avoid a fee
Answer:
$20.96
Step-by-step explanation:
He has $638.54 in his account and writes a check for $159.50. The amount of money he needs to stay at or above $500 is denoted by x.
638.54 - 159.50 + x >= 500
After writing a check, Malcom has $479.04 left in his account, which is below his cutoff.
479.04 + x >= 500
He must add at least x amount of dollars to his account to avoid a fee.
x >= 20.96
In order to avoid a fee, Malcom must add a minimum of $20.96 to his account.

The distance an object travels is determined by how fast it goes and for how long it moves. If an object’s speed remains constant, the formula is d=r*t , where d is the distance, r is the speed, and t is the time. If you drive at 50 miles per hour for 5 hours, how far will you have traveled? a. 200 miles b. 10 miles c. 250 miles d. 300 miles Please select the best answer from the choices provided A B C D
Answer:
d = r * t
r = 50 mph
this will be very easy.
d = r * t
r = 50 mph
t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.

12 POINTS TO THE BRAINLIEST ANSWER!!!! PLEASE HELP!! Tess and Dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book? Explain your answer using complete sentences. PLEASE ANSWER ALL QUESTIONS
Answer:
yes Dan and Tess have enough money because the price is 22.9075 after discount
Step-by-step explanation:
the original price of the book=24.50
the price of the book with taxes : 24.5+(24.5*10 %)=26.95 Dollars
the price for the students is : 24.50-(24.5*15%)=20.825
the price to students +tax= 20.825+(20.825*10%)= 22.9075
See what Tess did:she took 15 % from original price :24.50-(24.5*15%)=20.825
she took 10 % of discounted price :20.825.50*10%= 1.04125
adds it back to find the purchase amount:1.04125+20.825=21.86625
what Dan did:Dan takes 85% of the normal purchase price: 24.50*85%= 20.825
then compute 110% to the discounted price: 20.825*110%=22.9075
Dan is right, he will pay 22.9075 which is actually the price that the student pay for the book after the discount. what Tess is that she calculated the tax before discount, she has to calculate the tax after discount.
The length of the rectangle below is (2x-3) and the width is (x+7). Find the area of the rectangle in terms of x.
Answer:
area = 2x² - 17x - 21
Step-by-step explanation:
Area of the rectangle is:
area = (width*length)
area = (x+7)*(2x-3)
= x*2x + x*-3 + 7*2x + 7*-3
= 2x² - 3x - 14x - 21
= 2x² - 17x - 21
The area of the rectangle in terms of x should be [tex]2x^2 + 11x - 21[/tex]
Given that,
Length is 2x - 3.Width is x + 7.We need to determine the area of the rectangle
As we know that
The area of the rectangle be
[tex]= length \times breadth\\\\= (2x - 3) (x + 7)\\\\= 2x^2 +14x - 3x - 21\\\\= 2x^2 + 11x - 21[/tex]
Therefore we can conclude that The area of the rectangle in terms of x should be [tex]2x^2 + 11x - 21[/tex]

Helo please I need help
Answer:
9:16
Step-by-step explanation:
In a similar rectangle , the ratio of lengths should be equal to ratio of widths.
Ratio of lengths =
[tex] \frac{length \: of \: rectangle \: 1}{length \: of \: rectangle \: 2} = \frac{3}{4} [/tex]
Hence , Ratio of widths =
[tex] \frac{width \: of \: rectangle \: 1}{width \: of \: rectangle \: 2} = \frac{3}{4} [/tex]
Area of rectangle 1 = Length 1 × Width 1 = 3×3 = 9
Area of rectangle 2= Length 2 × Width 2= 4×4= 16
Ratio of areas of both rectangles =
[tex] \frac{area \: of \: rectangle \: 1}{area \: of \: rectangle \: 2 \: } = \: \frac{9}{16} [/tex]

A scale drawing of a living room is shown below 5.5 inches and 3 inches scale 1:30 what is the area of the actual living room? Round your answer to the nearest whole number
Answer:
14850 inches
Step-by-step explanation:
The complete question is...
A scale drawing of a living room is shown below:
A rectangle is shown. The length of the rectangle is labeled 5.5 inches. The width of the rectangle is labeled 3 inches. The scale is 1 to 30.
What is the area of the actual living room in square feet? Round your answer to the nearest whole number.
The ratio of the scale = 1:30
This means that the dimensions of the drawing has been reduced to 1/30 of the actual building's dimensions.
We first scale up the drawing to 30 times to get the dimensions of the actual building.
The length on the drawing = 5.5 inches
The real length of the actual building = 5.5 x 30 = 165 inches
The width of the drawing = 3 inches
The width of the actual building = 3 x 30 = 90 inches
The area of the actual building = length x width
==> 165 x 90 = 14850 inches

7. Find the value of:
a) The number when 40% of the number is 10
Step 1) Set up a proportion
Proportion: percent / 100 = x / number
In context of the problem, the proportion is: 40 / 100 = 10 / number
Step 2) Cross-multiply and solve
100 x 10 = 40 x N
1000 = 40N
N = 25
Answer: The number is 25
Answer:
25Step-by-step explanation:
Let the unknown number be x
[tex]40 \% \times x = 10 \\ \frac{40x}{100} = \frac{10}{1} [/tex]
Cross Multiply
[tex]40x = 100 \times 10 \\ 40x = 1000[/tex]
Divide both sides of the equation by 40
[tex] \frac{40x}{40} = \frac{1000}{40} [/tex]
Simplify
[tex]x = 25[/tex]

-1/2(3x-4)+3x=5/6
Please help
Answer:
x = -7/9
Step-by-step explanation:
The usual recommendation is to clear fractions first. Here, you can do that by multiplying both sides of the equation by 6.
6(-1/2(3x -4) +3x) = 6(5/6)
-9x +12 +18x = 5 . . . . . . . . . simplify
9x = -7 . . . . . . . . . . . . . . . . . subtract 12
x = -7/9 . . . . . .divide by 9

Another way to do this is to eliminate parentheses first.
-3/2x +2 +3x = 5/6
3/2x = -7/6 . . . . . . . . . collect terms, subtract 2
x = (-7/6)(2/3) = -7/9 . . . . multiply by 2/3

Solve for b.
y = mx + b
Answer:
b = y - mx
Step-by-step explanation:
So we are trying to solve for b in the equation y = mx + b. To do this, we will have to somehow get the b by itself on one side and all of the non-b parts of the equation on the other side.
y = mx + b
Subtract mx from both sides.
y - mx = b
b = y - mx
So we have not solved for b. We have found that b = y - mx.

find the dimension of the missing side of a triangle given the following measurements: A=75 sq. ft, b=15 ft, h=?
Answer:
h = 10 ft
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh
Here A = 75 and b = 15, thus
[tex]\frac{1}{2}[/tex] × 15h = 75 ( multiply both sides by 2 to clear the fraction )
15h = 150 ( divide both sides by 15 )
h = 10
