Answer:
Step-by-step explanation: If the square is 30 ft on one side the other side must be too. So 30x30 = 900. Now, we know the rectangle must also be 900 in area. So, the width must be 10feet and the length must be 90ft because 10x90 is also 900. How I got the length? I did 10x2+70.
Draw the Image of the following triangle after a dilation centered at the origin with a scale factor of 5/3
The graph of the image of the triangle in the question following the dilation by a scale factor of (5/3) with vertices (10, 15), (10, 10), (15, 10) created with MS Excel is attached.
What is a dilation transformation?In a dilation transformation, the dimensions of the original figure is changed by multiplying the lengths by a scale factor.
The coordinates of the vertices of the triangle in the are (6, 9), (6, 6), and (9, 6)
The coordinate of a point (x, y) following a dilation by a scale factor of k, centered at the origin is the point (k·x, k·y)
The coordinates of the vertices of the image of the triangle in the question following a dilation of 5/3 centered at the origin, are therefore;
(6, 9) [tex]\overset{R_{5/3}}\longrightarrow[/tex] ((5/3)×6, (5/3)×9) = (10, 15)
(6, 6) [tex]\overset{R_{5/3}}\longrightarrow[/tex] ((5/3)×6, (5/3)×6) = (10, 10)
6(9, 6) [tex]\overset{R_{5/3}}\longrightarrow[/tex] ((5/3)×9, (5/3)×6) = (15, 10)
The graph of the image of the triangle following a dilation by a scale factor of 5/3) can therefore be plotted using points (10, 15), (10, 10), and (15, 10) and the plot function on MS Excel

consider following recurrence relation. what will be the number next in series in place of question mark? 0, 3, 8, 15, 24, 35, 48, ?
The number that will be next in the series will be 63 .
In the question ,
a recurrence relation is given that is 0, 3, 8, 15, 24, 35, 48, ? .
we have to find the number that will come in place of question mark .
On carefully examining the series , we can see that
3 - 0 = 3
8 - 3 = 5
15 - 8 = 7
24 - 15 = 9
35 - 24 = 11
48 - 35 = 13
we can se that increments 3,5,7,9,11,13,... form an Arithmetic Progression
with first term as 3 and common difference as 2 ,
So ,the next increment will be 13+2 = 15
let the next term be "x" .
x - 48 = 15
x = 15 + 48 = 63
the number in place of ? is 63 .

What was the original voltage in the circuit?
Answer:
The voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27 /125 of a volt and has been reduced 3 times.
Write the voltage in exponential form.
What was the original voltage in the circuit?
Step-by-step explanation:
voltage = v
v³ - exponential form
v³ = 27/125
make v³ a fraction so v³/1 then cross multiply
so... 125v³ = 27 then v³ = 27/125 or v³ = 0.216 if you like decimals better then to get v by it self you cube root mean v = ∛27/125
original voltage in circuit - v = ∛27/125
The diameter of the sun is about 1.4 x 10 to the power of 6 km. The diameter of the earth is about 13,000 km. What is the approximate ratio of the diameter of the sun to the diameter of the earth ?
Answer:108x10 to the 2nd power
Step-by-step explanation: Given, the diameter of the Sun is 1.4 × 10⁹ m. The diameter of the Earth is 1.2756 × 10⁷ m. We have to compare the diameters by division. Therefore, the diameter of the Sun is nearly 110 times the diameter of the Earth, So i would say 108x10 squared

1/8 = x
Answer: x = -2
Step-by-step explanation:
X is -2 because whenever you get a negative exponent you gotta make it into a fraction which is [tex]\frac{1}{4}[/tex] because I ignored the negative sign for a second and did it normally so 2 to the power of 2 is 4 put it as a fraction 1 over 4.

josh scored x marks in this math exam. he scored 8 more marks in english than math, and 3 more marks in geography than in math. if he received a total of 200 marks for the 3 subjects, find how many marks he scored in math.
Answer:
Math = 63
Step-by-step explanation:
Math = x
Eng = Math + 8
Geo = Math + 3
Math + Eng + Geo = 200
Substitute Eng and Geo with information above
Math + (Math + 8) + (Math + 3) = 200
3Math + 8 + 3 = 200
3Math + 11 = 200
3Math = 200 - 11
3Math = 189
Math = 189 ÷ 3
Math = 63
A recipe for stir fry calls for 6 cups of rice for every 4 cups of veggies. Suppose a restaurant is making a large batch of stir fry using 15 cups of veggies. How much rice would they need? Start by labeling the double number line with the cups of veggies and cups of rice that the recipe calls for. Veggies (cups) 0 4 Rice (cups) 0 6 Great job! To find how many cups of rice they’d need for 15 cups of veggies, it can be helpful to first find the unit rate, or the amount of rice needed for 1 cup of veggies. Partition the number line to find the number of cups of rice needed for every 1 cup of veggies. Veggies (cups) 0 4 Rice (cups) 0 6 Good work! Label the bottom number line to find the number of cups of rice the restaurant would need for 1 cup of veggies.
Answer:
(i)15v=10r
Step-by-step explanation:
let no. of rice=r
let stir fry=s
let no. of veggies=v
6r=4v
then if, v=15, r=?
if 6r=4v, then v=6/4r

A scale on a map is 1 200 000. Work out the distance on the map, in cm, if the real distance is 10 km 15 km 4 km
The distance on the map, in cm, given the real distances, and the scale of the map are:
10 km = 5 cm15 km = 7.5 cm4 km = 2 cmHow to find the distance on the map?A scale of 1 : 200, 000 means that every 1 cm on the map is 200, 000 cm on the ground.
To find the distance on the map of 10 km, first convert it to cm:
= 10 km x 100, 000 cm per km
= 1, 000, 000 cm
The distance on the map is therefore:
= 1, 000, 000 / 200, 000 cm scale
= 5 cm on map
The distance of 15 km on the map is:
= (15 km x 100, 000) / 200, 000
= 7.5 cm
The distance of 4 km is:
= (4 x 100, 000) / 200, 000

The probability that the mean number of hours spent playing video games is less than 42.8 hours is 0.15866
we are given the mean of ( m )= 43 hours and the standard deviations (s) of 2 hours, where the sample size (n) = 100.
Obtain the Zscore ;
Z = (x - m) ÷s/sqrt(n)
Z = (42.8 - 43) ÷ 2/sqrt(100)
Z = - 0. 2 ÷ 0.2
Z = - 1
so we need the probability of P(Z < - 1), from the table of z-score the probability of a z-score of -1 is 0.15866.Hence, the probability that the mean number of hours spent playing video games is less than 42.8 hours is 0.15866

Answer:
Step-by-step explanation:
We have to the graph from x = -4 to x = 2
2y + x + 3 = 0
Rearrange the equation to make y the subject
2y = -x - 3
y = (-1/2)x -3/2
-3/2 is the y intercept
the gradients is -1/2
since the value is negative, the graph will be sloping downwards
Point your pen at y = -3/2 on the y axis (-3/2 is -1.5)
go 1 point down and 2 points to the right, make a point and connect these 2 dots and make a line across the graph.
Do the same with the other equation:
3y - x + 1 = 0
3y = x - 1
y = (1/3)x -1/3
y intercept is -1/3
gradient is 1/3
point your pen at -1/3 on the y axis, go 1 point up and 3 points to the right
and mark this point and connect these 2 points and make a line across the graph.
A person who weighs 150 pounds weighs 25 pounds on the Moon. Suppose an object weighs 80 pounds on the Moon. What’s the objects weight on the Earth?
Answer:
480 lbs
Step-by-step explanation:
First, find the ratio of weight on the moon to weight on the earth. I will put the two known values in a fraction like this:
[tex]\frac{25}{150}[/tex]
Now, I can create a proportion, making sure to keep the same types of measurements in the numerator and denominator. I will use w for the unknown weight on earth.
[tex]\frac{25}{150}=\frac{80}{m}[/tex]
Now, I will simplify the fractions as much as I can.
[tex]\frac{1}{6}=\frac{80}{m}[/tex]
Now, I can see a correlation. 1 times 80 is 80, so 6 times 80 is m. Simplified, here is the answer!
[tex]6*80=m\\480=m\\m=480[/tex]
Answer:
480 pounds
Step-by-step explanation:
we times for objects on earth and divide for objects on the moon by the same number
150
[tex]150 \div x = 25[/tex]
150/-25=-x
-6/-1= -x/-1
6=x
[tex]150 \div 6 = 25[/tex]
so when in object is on earth you multiple by x Wich 6

In a discount clothing store, all sweaters are sold at one fixed price and all shirts are sold at another fixed price. If one sweater and four shirts cost $55, while four sweaters and five shirts costs $110, find the price of one sweater and the price of one shirt.
The price of one sweater is $15 and the price of one shirt is $10.
What is the price of one sweater and one shirt?The first step is to form a set of linear equations using the information provided in the question:
s + 4p = $55 equation 1
4s + 5p = $110 equation 2
Where:
s = price of one sweater p = price of one shirtIn order to determine the value of p, take the following steps:
Multiply equation 1 by 4
4s + 16p = 220 equation 3
Subtract equation 2 from equation 3:
11p = 110
Divide both sides of the equation by 11
p = 110 / 11
p = 10
In order to determine the value of s, substitute for p in equation 1:
s + 4(10) = $55
s + 40 = 55
s = 55 - 40
