Mr. Lloyd wants to build a dollhouse for his daughter that is proportional to their house. He measured the living room of his house and it is 12ft by 16 feet. What will be the dimensions of the doll house living room if every foot of the actual house is equal to 1/2 inch in the dollhouse?
Answer:
48 inches
Step-by-step explanation:
Every foot is half an inch. So if there is 12 feet then that means there is 6 inches because 12x0.5= 6. 16x0.5= 8, which means 16 feet equals 8 inches. Now that we have the converted measurements we must find out the dimensions of the dollhouse living room. 6 inchx8 inch = 48 inches.

A book sold 36,700 copies in its first month of release. Suppose this represents 7.1% of the number of copies sold to date. How many copies have been sold to date? Round your answer to the nearest whole number.
PLEASE HELP!
Answer
516,901
Step-by-step explanation:
36,700/7.1%
you have to change the 7.1% to a decimal so its now
36,700/0.071= 516,901.4084507
round it to the nearest whole number is 516,901
find the smallest possible number which when divided by 27, 30 or 45 gives a remainder of 3
Answer:
273
Step-by-step explanation:
Answer:
273
Step-by-step explanation:
First of all find the LCM of 27, 30, & 45 then add 3 to it u'll get the smallest value of n. So, LCM of 27, 30 & 45 is 270. Therefore, the smallest value of n = 270 + 3 = 273

$400 interest is earned on a principal of $2,000 at a simple interest rate of 5% interest per year. For how many years was the principal invested?
Answer:
4 years
Step-by-step explanation:
Given data
Simple interest= $400
Principal= $2000
Rate= 5%
The simple interest formula is given as
SI=PRT/100
substitute and solve for T
400=2000*5*T/100
cross multiply
400*100= 10000*T
40000=10000T
T= 40000/10000
T= 4 years
Hence the time taken is 4 years
what does anyone know what perimeter is and area to help for me friends
Item 9 Write an equation that you can use to find the value of x. Perimeter of triangle: 16 in.
Answer:
16 = 3x
Step-by-step explanation
Find the diagram attached.
Perimeter = sum of all its sides
Sum of all its sides= x+x+x
Sum of all its sides = 3x
Given perimeter = 16in
Equating both;
3x = 16
x = 16/3
x = 5.33in
Hence the value of x is 5.33 and the required equation is 16 =3x
need help, tyyyyyyyy
Answer:
$30
Step-by-step explanation:
s = shorts
t = tshirts
s + 2t = 60
s + 3t = 75
s + 2t = 60
rewrite
-2t -2t
s = 60 - 2t
s + 3t = 75
plug in
(60 - 2t) + 3t = 75
solve
60 - 2t + 3t = 75
60 + t = 75
-60 -60
t = 15
s + 2t = 60
plug in
s + 2(15) = 60
s + 30 = 60
-30 -30
s = 30
Maggie uses 6.9 pints of white paint and blue paint to paint her bedroom walls. 3 5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
2.76 pints
Step-by-step explanation:
Given that:
Tottal amount of paint used = 6.9 pints
The faction of white paint used = 3/5
Hence, Amount of white Paint used :
3/5 * 6.9 = (3 * 6.9) / 5 = 4.14 pints of white paint.
Pints of blue paints used :
Total pints - pints of white used
6.9 - 4.14 = 2.76 pints of blue paint

Explain the difference in meaning between 8^2 +2^2 and (8 + 2)^2?
8^2 +2^2 is 68 because you only square the integer. In (8 + 2)^2, you square the product of the equation.
Answer:8^2+2^2=68 and (8 + 2)^2=100
Step-by-step explanation:
8^2+2^2
=64+2^2
=64+4
=68
(8+2)^2
=10^2
=100

Write the slope-intercept form of the linear equation of a line with slope of -3/4 and a y intercept of (3,0)
Answer:
y= -3/4 +3
Step-by-step explanation:
slope-intercept form formula is y=mx+b
mx= slope
b= y-intercept
Therefore, if you input the numbers into the equation it is
y=-3/4 +3
it is 3 because this point is located at 3 on the y-axis

Quotient of a number and 3 increased by -7 Equals negative 144
Answer:
x = -411
Step-by-step explanation:
Number = x
Quotient of a number and 3 : [tex]\frac{x}{3}[/tex]
(x/3) increased by (-7) : [tex]\frac{x}{3}+ (-7)[/tex]
[tex]\frac{x}{3} -7 = - 144\\\\\frac{x}{3}= -144 + 7\\\\\frac{x}{3}= -137\\\\x = -137*3[/tex]
x = - 411
Answer:
-411
Step-by-step explanation:
x / 3 + -7 = -144
x / 3 = -144 + 7
x = -137 x 3
x = -411
Hope that helps!
what is x and y. help plz!!!!!!!
Answer:
x = 11
y = 1
Step-by-step explanation:
N : M
8 : 1
8 N = 1 M
since there is 1 M per every 8 N, y would be 1
to find x, just take 88 and divide it by 8 to get 11
The scale of a map is 1 inch : 10 miles. What is the scale of the map area to the actual area? 1 in. : 10 mi 1 in. : 20 mi 1 in. : 20 mi 1 in. : 100 mi
Answer:
1 in. : 100 mi
Step-by-step explanation:
Scale = 1 inch : 10 miles
In the scale, the quantity is Length
The relationship between length and Area is;
Area = Length * Length
So inch becomes inch^2
1 inch * 1 inch = 1 i
10 miles * 10 miles = 100
The correct option is;
1 in. : 100 mi
Determine the x-intercepts and y-intercepts for the following equation:
−5x+2y−10=0
Answer:
Look below.
Step-by-step explanation:
In order to find these intercepts you have to know that you have to substitute y and x for zero to find the intercept. Look below to see the steps.
X-intercept:
(substitute y for 0 in the equation and use order of operations to solve)
−5x+2y−10=0
−5x+2(0)−10=0
x=-2
Y-intercept:
(substitute x for 0 in the equation and use order of operations to solve)
−5x+2y−10=0
−5(0)+2y−10=0
y=5

Stephen's lunch bill is currently at $8.33. Stephen orders a fruit salad for take-out, and wants to leave $2.25 as a tip for his server. He has $10 and a $5 bill. How much change after paying for his lunch, the fruit salad, and the tip?
Answer:
$1.53
Step-by-step explanation:
The computation of the change in the bill is shown below:
Total money he has to pay is
= $8.33 + $2.25
= $13.47
And, he have
= $10 + $5
= $15
So, the change would be
= $15 - $13.47
= $1.53
A rational function g is given below. Find all values of a for which g(a)=16. g(x)=(4)/(x+1)+(20)/(x^(2)+2x+1)
Answer:
a = 2/3
Step-by-step explanation:
(4(x+1) + 20 )/(x+1) = 16
4x + 4 + 20 = 16x + 16
12x = 8
x = 2/3

HELP ASAP.!!!!!!! Jahlil is saving money at a constant rate to buy a new TV. After saving for $3$ months, Jahlil has $\$330$ . After saving for $5$ months, Jahlil has $\$510$ . Construct a function that models the relationship between the amount of money Jahlil has saved and the number of months he has saved for. Show or explain how you constructed the function. Respond in the space provided.
Answer:
y=90x+60
Step-by-step explanation:
x=months
y=dollars
Find dollars/month by finding the slope.
(3, 330), (5, 510)
-> (510-330)/(5-3) -> 90
Since its a constant rate, the function will be in the form, y=mx+b, and since we found the slope we can plug m=90.
y=90x+b
To find be, we simply substitute one of the points.
330=90(3)+b
b=60
Thus, plugging it in,
y=90x+60
