Quadrilateral EFGH is a scaled copy of quadrilateral ABCD. Select the true statement.
Answers
Answer:
segment EF is twice as long as segment AB
Step-by-step explanation:
Quadrilateral EFGH and quadrilateral ABCD are similar polygons. We can say that two polygons are similar if their corresponding angles are equal to each other and their corresponding sides are proportional to each other.
From the image attached, we can see that side CD and side GH are corresponding sides. The ratio of their sides are to be proportional.
GH / CD = 12 / 6 = 2
Therefore Quadrilateral EFGH is twice the size of Quadrilateral ABCD. Since side EF and side AB are proportional, therefore segment EF is twice as long as segment AB

I thought of a two-digit number. The unit digit of my number is 7 more than the tens digit cubed. What is my number?
Answers
Answer:
18.
Step-by-step explanation:
If the tens digit is x^3 the unit digit is x^3 + 7
So 10 * x^3 + x^3 + 7 < 100 (as its a 2 digit number).
11x^3 < 93
x^3 < 8 5/11
x < 2.04
As x must be an integer it is either 1 or 2.
It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.
The answer is 1 and (1+7) = 18.
Answer:
18.

11x^3 < 93

x < 2.04
As x must be an integer it is either 1 or 2.
It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.
The answer is 1 and (1+7) = 18.

Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Cost per bulb = $1.50
Cost per pot = $1.25
Bag of potting soil = $10.00
Budgeted amount to spend ≤ 20
Cost :
Bag of potting soil + (Cost per bulb + cost per pot)*number of tulip bulbs ≤ 20
$10 + ($1.50 + $1.25)t ≤ $20
$10 + 2.75t ≤ 20
$2.75t ≤ $20 - $10
$2.75t ≤ $10
t ≤ $10/$2.75
t ≤ 3.636
Hence, t = maximum number of tulip bulbs she can purchase is 3.636,
Since the exact number of tulip bulb she can purchase is a decimal which is impossible in an actual scenario. Hence, In other to spend not more than $20.00
t ≤ 3

Ruby is moving from Minneapolis to Chicago, which is 400 miles away. She is traveling at an average speed of 50 miles per hour. Ruby stops for gas after a couple of hours and wonders how much further she needs to go. If y represents distance and x represents time, which linear equation would indicate the amount of miles Ruby still has to travel to Chicago?
Answers
Answer:
y = 400 - 50x
Step-by-step explanation:
From Minneapolis to Chicago = 400 miles
Speed of travel = 50 miles per hour
y = distance ; x = time
Distance = speed * time
Distance moved before stopping for gas:
50 * x = 50x
y = distance left to cover ;
400 m = total distance
50x = distance already moved
Therefore,
y = 400 - 50x
Answer:
Step-by-step explanation:
y= -50x + 400

explain why the quadratic relation y=2x^2+3x+5 would have no zeros
Answers
Complete the square to rewrite the quadratic:
2 x² + 3 x + 5 = 2 (x² + 3/2 x) + 5
... = 2 (x² + 3/2 x + 9/16 - 9/16) + 5
... = 2 (x² + 3/2 x + (3/4)²) + 5 - 9/8
... = 2 (x + 3/4)² + 31/8
Any real number squared becomes non-negative, so the quadratic expression has a minimum value of 31/8, which is greater than 0, and so there are no (real) x for which y = 0.

The mean mass of the 15 players in a rugby team is 85.2kg the mean mass of the team plus a substitute is 85.4kg what is the mass of the substitute ?
Answers
Answer:
88.4 kg
Step-by-step explanation:
Since we are given the mean we will need to multiply the mean by how many players there are on the team to find the total mass. (The second mean will be multiplied by 16 because it is the number of players on the team plus the substitute)
85.2 x 15 = 1,278
85.4 x 16 = 1,366.4
Subtract the first mass from the second because this will remove the mass of the 15 other players.
1366.4 - 1278 = 88.4
88.4 kg is the mass of the substitute.

The farmer decided that he ordered enough planks for an arena that measured 115 1/4 ft by 63 1/2 ft. Is he correct? Explain.
What questions do you need to answer this question? Please help
Answers
Answer:
The question we need to answer is what is the perimeter of the arenaStep-by-step explanation:
The question we need to answer is what total length of plank did the farmer ordered for the arena.
to solve for the length of plank to cover the arena we need to solve for the perimeter of the arena.
given data
length L= 115 1/4 ft = 115.25ft
width W= 63 1/2 = 63.5ft
perimeter= 2L+2W
perimeter= 2(115.25)+2(63.5)
perimeter= 230.5+127
perimeter= 357.5ft
This means that the farmer ordered a total length of 357.5ft of plank

Use the GCF and the distributive property to express the sum as a product 35+25
Answers
Answer:
5(5+7) = 5(5) + 5(7)Step-by-step explanation:
Given the expression 25+35.
Given A, B and C, according to distributive property:
A(B+C) = AB + BC
A is distributed over B and C where A is the GCF in this case. Applying this in the expression given
25 = 5 * 5
35 = 5* 7
25+35 = (5*5)+(5*7)
25+35 = 5(5+7)
5(5+7) = 5(5) + 5(7) (Distributive property)
