there are 300 window for b buildings. assuming there is an equal number of windows per building, how many windows does each building have
Answer:
[tex] x = \frac{300}{b} [/tex]
Step-by-step explanation:
We are given that, "b" number of buildings has 300 windows.
Let b represent the number of buildings.
Let x represent the number of windows per building.
Thus, the following equation can be used to expressed the number of windows for b buildings:
Number of buildings*number of windows per building = 300 windows
[tex] x*b = 300 [/tex]
The number of windows each building has would be:
[tex] \frac{x*b}{b} = \frac{300}{b} [/tex]
[tex] x = \frac{300}{b} [/tex] windows per building

M is the midpoint of ST. S(-8, 9) and M(-10, 14). Find the coordinates of the other endpoint, T.
Answer:
T = (-12, 19)
Step-by-step explanation:
We know that the definition of the midpoint is ...
M = (S + T)/2
Solving for T gives ...
T = 2M -S
T = 2(-10, 14) -(-8, 9) = (-20+8, 28-9)
T = (-12, 19)
urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each. if sergio spends at least 70 dollars he will recieve free shipping on his order. write and inequality to determine how much sergio needs to spend on each gift to order to receive free shipping
[tex]7.25 \leqslant x[/tex]
Step-by-step explanation:
you do 1.5×8 to see how much shipping cost
you get 12 then subtract 12 from 70 and you get 58, then you do 58÷8 and you get $7.25
so he needs to spend $7.25 or more on each friend. (im pretty sure)
The amount urgio needs to spend on each gift in order to receive free shipping is 7.25.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Given that urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each.
Let the cost of each gift = c
urgio is buying gifts for 8 friends = 8 gifts
Hence, the Inequality equation is written as:
(c + $1.50)× 8 ≥ $70
8c + 12 ≥ 70
8c ≥70 - 12
c ≥ 58/8
c≥ 7.25
Therefore, the amount urgio needs to spend on each gift in order to receive free shipping is 7.25

Nina is training for a marathon. She can run 4 1/2 kilometers in 1/3 of an hour. At this pace, how many kilometers can Nina run in 1 hour
Answer:
13½ kilometers
Step-by-step explanation:
If Nina runs 4½ km in ⅓ of an hour, at this pace, the number of km she'd run in an hour can be calculated as follows.
Let x be the number of km to run in an hour.
4½km => ⅓ hr
x km => 1 hr
Cross multiply
[tex] 1*4\frac{1}{2} = \frac{1}{3}*x [/tex]
[tex] 4\frac{1}{2} = \frac{x}{3} [/tex]
Multiply both sides by 3
[tex] 4\frac{1}{2}*3 = \frac{x}{3}*3 [/tex]
[tex] \frac{9}{2}*3 = x [/tex]
[tex] \frac{27}{2} = x [/tex]
[tex] 13\frac{1}{2} = x [/tex]
x = number of km Nina runs in 1 hour = 13½ kilometers
4. Evaluate the function at each specified value of the independent variable and simplify. (If an answer is undefined, enter UNDEFINED.) 5. Evaluate the function at each specified value of the independent variable and simplify. (If an answer is undefined, enter UNDEFINED.)
Answer:
See below.
Step-by-step explanation:
4)
So we have the function:
[tex]g(y)=7-6y[/tex]
And we want to find:
[tex]g(s+1)[/tex]
So, substitute y for (s+1):
[tex]g(y)=7-6y\\g(s+1)=7-6(s+1)\\[/tex]
Distribute:
[tex]g(s+1)=7-6s-6[/tex]
Subtract:
[tex]g(s+1)=-6s+1[/tex]
5)
So we have the function:
[tex]h(t)=t^2-2t[/tex]
And we want to find:
[tex]h(x-3)[/tex]
So, substitute t for (x-3):
[tex]h(t)=t^2-2t\\h(x-3)=(x-3)^2-2(x-3)[/tex]
Square and distribute:
[tex]h(x-3)=(x^2-6x+9)+(-2x+6)[/tex]
Combine like terms:
[tex]h(x-3)=(x^2)+(-6x-2x)+(9+6)[/tex]
Add:
[tex]h(x-3)=x^2-8x+15[/tex]
And those are our answers :)
En un supermercado tienen dos contadores eléctricos de flujo de personas 1 registra de 3 en 3 y el otro de 5 en 5 en el momento que ambos se detienen unos señala de 840 y el otro de 560 diga Cuál de los dos es el que marca de 3 en 3?
Answer:
El contador que señala 840 registra de 3 en 3.
Step-by-step explanation:
Existe un truco para determinar si un número es múltiplo de 3, si la suma de sus dígitos es 3 o uno de sus múltiplos, entonces el número es un múltiplo de 3. En consecuencia, corresponde al contador eléctrico que registra de 3 en 3 y el otro contador eléctrico sería el que registra de 5 en 5.
Primer contador: 840
[tex]x = 8+4+0[/tex]
[tex]x = 12[/tex]
12 es un múltiplo de 3, por tanto, este contador es el que registra de 3 en 3.
Segundo contador: 560
[tex]x = 5+6+0[/tex]
[tex]x = 11[/tex]
11 no es un múltiplo de 3. Asimismo, todo número que sea múltiplo de 5 termina en 5 o 0, entonces este contador es el que registra de 5 en 5.
El contador que señala 840 registra de 3 en 3.

Answer:
49, 35 and 32 are composite and the rest are orime numbers
Answer:
[tex] \boxed{ \bold{ \huge{\boxed {\sf{49 \: , \: 35 \: , \: 32}}}}}[/tex]
Step-by-step explanation:
Composite numbers are whole numbers that can be divided by numbers other than itself and 1.
Among 49 , 35 , 32 , 41 and 47,
: 49 , 35 and 32 are composite numbers.
49 is a composite number as it comes in the multiplication table of 1 , 7 and 49 . So, this means it comes in the table of more than 2 numbers. 35 is a composite number as it comes in the multiplication table of 1 , 5 , 7 and 35.32 is a composite number as it comes in the multiplication table of 1 , 2 , 4 and 16. 41 is not a composite but a prime number as it comes in the multiplication table of only 1 and 41 [ 1 and itself ] 47 is not a composite but a prime number as it comes in the multiplication table of only 1 and 47 [ 1 and itself ]Hope I helped!

Stuck on this 6/9 times 3
Answer:
2
Step-by-step explanation:
6/9 * 3
First you can either simplify this to make it easier or directly multiply. Simplify it by dividing 3 on the 9.
6/3=2
Or you can multiply and it would be 18/9, because 6*3=18.
18/9=2

7/60=5/24w+11/12 please help!!!!
Answer:
Step-by-step explanation:
w = -3 and 21/25
The value of w in 7/60=5/24w+11/12 is 6/5.
Given,
7/60 = 5/24 w + 11/12
We need to solve for w.
How do we solve an equation?It depends on the type of equation given.
We need to keep the variable that we are solving for in one side and simplify the other terms.
Find the value of w.
We have,
7/60 = 5/24 w + 11/12
Subtract 11/12 on both sides.
7/60 - 11/12 = 5/24 w + 11/12 - 11/12
7/6 - 11/12 = 5/24 w
Simplify the left-hand side into a fraction.
(14 - 11 ) / 12 = 5 / 24 w
3 / 12 = 5 / 24 w
Multiply 24 / 5 on both sides.
24/5 x 3/12 = 24/5 x 5/24 w
6 / 5 = w
w = 6 / 5
Thus the value of w in 7/60=5/24w+11/12 is 6/5.

Use the figure to the right to find the value of PT. T is the midpoint of PQ.
PT = 5x +2 and TQ = 7x-6
PT=
(Simplify your answer.)
Answer:
22
Step-by-step explanation:
Given that T is the midpoint of line PQ, segments PT = 5x + 2, and TQ = 7x - 6 that are formed would be equidistant or congruent. PT = TQ.
Therefore:
[tex] 5x + 2 = 7x - 6 [/tex]
Let's find the value of x
Rearrange the equation, so that the terms having x would be on your left, while those without x would be on your right.
[tex] 5x - 7x = - 2 - 6 [/tex]
[tex] -2x = -8 [/tex]
Divide both sides by -2
[tex] x = 4 [/tex]
Plug in the value of x into the expression, 5x + 2, to find PT.
PT = 5(4) + 2 = 22.
What would be the fourth and fifth figures? How many dots will be in the 100th figure?
Answer:
4th=8 dots
5th=10 dots
100th=200 dots
Step-by-step explanation:
Since you’re adding two dots each time, it will always bed double the figure number.
4th=8 dots
5th=10 dots
100th=200 dots
Answer:
The fourth figure is 8 Dots
The fifth figure is 10 Dots
The hundredth figure will be 200 Dots
Step-by-step explanation:
The figure dots increase by two so we multiply the dot number by the amount of increase
which means
The Fourth figure have 4 dots so 4 × 2=8
The Fifth figure have 5 dots so 5 × 2 =10
The hundredth figure have 100 dots so 100 × 2 =200

A wildlife habitat houses 41 animals. There are three more reptiles than mammals in the habitat. There are seven fewer amphibians than mammals in the habitat. How many amphibians are there in the habitat?
Answer: 8
Step-by-step explanation:
Let mammals be represented by y
There are three more reptiles than mammals in the habitat. Therefore, Reptiles = y + 3
There are seven fewer amphibians than mammals in the habitat. Therefore, amphibian = y - 7
y + y + 3 + y - 7 = 41
3y - 4 = 41
3y = 41 + 4
3y = 45
y = 45/3
y = 15
Since amphibian = y - 7
= 15 - 7
= 8
There are 8 amphibians
