While sightseeing in Rome, Lance stopped to see the Colosseum. He learned that the height of the outer wall of the Colosseum measures 48 meters tall. If 1 meter is approximately 3.28 feet, about how high is the outer wall in feet?
Answer:
157.44 feet
Step-by-step explanation:
Given that:
Lance is out for sightseeing in Rome.
Lance went to see the Colosseum.
Height of the outer wall of the Colosseum = 48 meters
Unit Conversion formula:
1 meter = 3.28 feet
To find:
Height of the outer wall of the Colosseum in feet.
Solution:
It is simple problem for the conversion of unit where we already know the value in one unit and the conversion formula as well.
We have to simply find how much 48 meters will be when converted in feet.
1 meter = 3.28 feet
48 meter = 48 [tex]\times[/tex] 3.28 = 157.44 feet
Teri incorrectly solved the system of equations below. Correctly identify the error Teri made. 2x - 10 y = -30 x - 5y = 20 Step 1: x - 5y = 20 x = 5y + 20 Step 2: 2(5y + 20) - 10 y = -30 10y + 40 - 10y = -30 40 = -30
Answer:
See explanations below
Step-by-step explanation:
Given the system of equation
2x - 10 y = -30 ... 1
x - 5y = 20 ... 2
Step: From 2;
x = 20 + 5y ...3
Step 2: Substitute equation 3 into 1
2x - 10y = -30
2(5y+20) - 10y = -30
Open the bracket
10y + 40 - 10y = -30
10y - 10y + 40 = -30
0+40 = -30
40 = -30
The steps taken by Teri are correct all through. He didn't make any error whatsoever

Answer:
it's answer is 89 mm
Step-by-step explanation:
Perpendicular (p) = 80 mm
base(b) = 39 mm
hypotenuse (h) = ?
By using Pythagoras theorem,
h = √( p² + b²)
= √ ( 80² + 39²)
= √7921
=√(89)²
= 89 mm
Answer:
89 mm
Step-by-step explanation:
Use the pythagorean therom to solve for the hypotenuse which is (c).
Ex: a^2+b^3=c^2
Subsitute
80^2+39^2=c^2
6400+1521=c^2
6400+1521=c^2
Add
6400+1521=7921
Now you have the following equation...
7921=c^2
Sqaure both sides of the equation
sqrt7921=sqrtc^2
89=c
So C=89 mm there you go :)

Jan's house has four leaking taps. An average of 34 cL of water leaks from each tap every day. How many litres of water is lost from these four taps in August?
Answer: 42.16l
Step-by-step explanation:
First, we should note that August has 31 days. Since Jan's house has four leaking taps and an average of 34 cL of water leaks from each tap every day. The four taps will leak (34 × 4) = 136 cL everyday.
The amount of litres of water that is lost from these four taps in August would be:
= 136cL × 31
= 4216 cL
= 42.16L
We should note that 100cL = 1L
Candice is taking a group nature hike in a park. There is a
$11.00 fee just to enter the park. In addition, the tour
group charges $0.14 per mile they hike. She brought
$81.00 with her. Find the maximum amount of miles
Candice can hike.
Answer:
500 miles
Step-by-step explanation:
81-11 is 70. 70 divided by .14 is 500 so that's 500 miles she can bike.
Answer:
500 miles
Step-by-step explanation:
To find out how many miles Candice can hike at max, use the equation 11 + 0.14x = 81.
11 + 0.14x = 81
Subtract 11 from both sides. This undoes the +11.
0.14x = 81 - 11
Subtract 11 from 81 to get 70.
0.14x = 70
Divide both sides by 0.14. This undoes the multiplication by 0.14.
x = 70/0.14
I recommend converting 0.14 into a fraction. That would be 7/50.
x = 70/(7/50)
Find the reciprocal of 7/50 (50/7). Switch the sign from division to multiplication.
x = (70 * 50)/7
Multiply 70 by 50 to get 3500.
x = 3500/7
Divide 3500 by 7 to get 500.
x = 500
At max, Candice can hike 500 miles.

-5x2(4x3 - x2)2 ?
O Distribute -5x?
Square 4x - x2
Subtract 4x3 - 2
Answer:
Square 4x³ - x²
Step-by-step explanation:
Given the expression -5x²(4x³ - x²)²
The first step in simplifying the expression is to open the parenthesis by taking the square of 4x³ - x² as shown;
-5x²(4x³ - x²)²
= -5x²[(4x³)²- 2x²(4x³) + (x²)²]
= -5x²[16x^6- 8x^5 + x^4]
Hence the correct answer is Square 4x³ - x²

Answer:
x = 6
Step-by-step explanation:
angles 1 and 2 are equal because the entire angle is bisected
so, 5x - 2 = 4x + 4
x - 2 = 4
x = 6
If you substitute 6 into each expression, they should be equal:
4(6) + 4 = 5(6) - 2

Answer:
This survey may be unfair because they are asking the question to a group of kids who are already biased because they all play a specific sport and are most likely going to chooses that sport. Therefore the answers will most likely be basketball because it is the basketball team taking the survey

vertical lines yes, theyre across from each other making it vertical line
Vertical angles are the angles at the opposite sides of a transversal

Answer:

Step-by-step explanation:
Opposite sides and angles of a parallelogram are equal.
So,
3x - 1 = 35
Add 1 to both sides
3x = 35 + 1
3x = 36
Divide 3 to both sides
x = 36 / 3
x = 12

Question:
Alex skateboards at a constant speed from his house to school 3.8 miles away. It takes him 18 minutes.
a. What fraction represents his constant speed, c?
b. After school, Alex skateboards at the same constant speed to his friend’s house. It takes him 10 minutes. Write the fraction that represents constant speed, c, if he travels a distance of y.
c. Write the fractions from parts(a) and (b) as a proportion, and solve to find out how many miles Alex’s friend’s house is from school. Round your answer to the tenths place.
Answer:
(a) [tex]c = \frac{3.8}{18}[/tex]
(b) [tex]c = \frac{y}{10}[/tex]
(c) 2.1 miles
Step-by-step explanation:
Solving (a):
Given
[tex]Distance = 3.8\ miles[/tex]
[tex]Time = 18\ minutes[/tex]
Required
Determine the constant speed, c.
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
So, we have:
[tex]c = \frac{3.8}{18}[/tex]
Solving (b):
Given
[tex]Distance = y[/tex]
[tex]Time = 10\ minutes[/tex]
Required
Determine the constant speed, c.
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
So, we have:
[tex]c = \frac{y}{10}[/tex]
Solving (c): Write (a) and (b) as proportions and solve for y.
As a proportion, we have
[tex]\frac{y}{10} = \frac{3.8}{18}[/tex]
Multiply both sides by 10
[tex]10 * \frac{y}{10} = 10 * \frac{3.8}{18}[/tex]
[tex]y = 10 * \frac{3.8}{18}[/tex]
[tex]y = \frac{38}{18}[/tex]
[tex]y = 2.11111[/tex]
[tex]y = 2.1\ miles[/tex] ---- approximated

Answer:
x=-1
Step-by-step explanation:
If PTS ~ PQR, find the value of x.
Step-by-step explanation:
[tex] \frac{6x - 2}{30} = \frac{5x + 13}{36} \\ 36(6x - 2) = 30(5x + 13) \\ 6(6x - 2) = 5(5x + 13) \\ 36x - 12 = 25x + 65 \\ (36 - 25)x = (65 + 12) \\ 11x = 77 \\ x = \frac{77}{11} \\ x = 7[/tex]
You can use the properties that similar triangles have sides scaled.
The value of x is 7.
Since it is given that PTS ~ PQR, thus, let the scaling is done by factor f. Then we have:
[tex]|PT| = f \times |PQ|\\ |TS| = f \times |QR|\\ |SP| = f \times |RP|[/tex]
Thus, we get the ratio of length of PT and length of TS as:
[tex]\dfrac{|PT|}{|TS|} = \dfrac{f \times |PQ|}{f \times |QR|} = \dfrac{|PQ|}{|QR|}[/tex]
How to find the value x?Using the values specified in the given figure for above obtained equation, we get:
[tex]\dfrac{|PT|}{|TS|} = \dfrac{|PQ|}{|QR|}\\
\\
\dfrac{36}{30} = \dfrac{5x + 13}{6x-2}\\
\\
\text{Cross multiplying, the denominators},\\\\
36(6x-2) = 30(5x+13)\\
216x - 72 = 150x + 390\\
216x - 150x = 390 + 72\\
66x = 462\\\\
x = \dfrac{462}{66}\\\\
x = 7[/tex]
Thus, the obtained value of x is 7.
