A 12ft. ladder is leaned against a wall. If the base of the ladder is 5ft. from the wall, how high up on the wall does the ladder reach?
Answer:
use Pythagoras theorem
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ \\ a = 5 \\ b = (required \: lenth) \\ c = 12 \\ \\ { {5}^{2} } + {b}^{2} = {12}^{2} \\ {b}^{2} = {12}^{2} - {5}^{2} \\ b = \sqrt{119} \\ b = 10.90871211[/tex]

Answer:
4
Step-by-step explanation:
Step 1: Arrange the numbers in ascending order
1,2,2,3,3,3,3,5,5,7,7,9,9,10
Step 2: Find the two middle numbers, m1 and m2
3, and 5
Step 3: Find the average of m1 and m2
(3+5)/2 = 4
(m1 + m2)/2. Where, m1 and m2 are the two middle numbers.
median is 4

Find the area of the circle. Round your answer to the nearest hundredth
Answer:
7.07
Step-by-step explanation:
Answer:
7.07 in²
Step-by-step explanation:
Given that,
→ Diameter = 3 in
→ Radius (r) = 3/2 = 1.5 in
Formula we use,
→ Area of circle = πr²
Then the area of circle will be,
→ πr²
→ 3.14 × 1.5 × 1.5
→ 7.065
→ 7.07 in²
Hence, the solution is 7.07 in².

To predict volcanic eruptions scientists may use a seismograph to detect small earthquakes out of the 169 active volcanoes in the U.S. about 130 are in Alaska. About how many active U.S. volcanoes are not is Alaska?
Answer:
39 active volcanoes.
Step-by-step explanation:
Subtract 169 (whole) from 130 (part). 9 - 0 = 9, 6 - 3 = 3, and 1 - 1 = 0. Therefore, 169 - 130 = 39

Step-by-step explanation:
Value of 't' = 4
To FindDifference between the population of the two cities
Solution[tex] \text{{Assuming the population of two cities as}} \: \text{c}_1 \text{ and} \: \text{c}_2[/tex]
[tex] \text{ In Case of }\text{c}_1[/tex]
[tex]\text{c}_1 = -150\text{t} + 50,000 \\ \implies \text{c}_1 = - 150 \times 4 + 50,000 \\ \implies \text{c}_1 = - 600 + 50,000 \\ \implies \text{c}_1 = 49,400[/tex]
[tex] \text{ In Case of }\text{c}_2[/tex]
[tex]\text{c}_2 = 50\text{t} + 75,000 \\ \implies \text{c}_2 = 50\times 4 + 75,000 \\\implies \text{c}_2 = 200+ 75,000 \\ \implies \text{c}_2 = 75,200[/tex]
Now, We need to find the difference in their population
[tex]\text{c}_2 - \text{c}_1 \\ = 75,200 - 49,400 \\ = 25,800[/tex]
[tex]\therefore \text{Difference between their Population=} \red{25,800}[/tex]

Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4 In other words, a change of 1 unit in x corresponds to a change of 0.4 units in y. Graph the line and write the equation of the line.
PLS HELP WILL GIVE BRANLIEST + 20 POINTS
So here the 'unit rate of change' means the slope. It's also referred to as 'rise over run'. A line can be expressed in the form y=mx+b, where m is the slope and b is the y intercept. So here, m is equal to 0.4 and the line is y=0.4x
Think of it this way: if you plug in 1 for x, you get 0.4 for y. So that matches what the problem was saying about a change of 1 unit in x means 0.4 units in y. To graph it, start at 0,0 and move 0.4 up in y direction (rise) and 1 to the right in the x direction (run). If you keep doing that and connect the points, that will be the line

Find the surface area of a triangular prism that has a height of 11 meters and the triangular base shown. All dimensions are in meters.
S
A
=
m
2
Answer:
146 m²
Step-by-step explanation:
The total base area = base x length = 4 x 11 = 44 (1)
The area of each triangular surface = /2 x base x height = 1/2 * 4 * 3.5 = 7 and the areas of both triangular surfaces = 2 x 7 = 14 (2)
The surface area of each of the lateral surfaces = side of triangle x length = 4 x 11 = 44
The area of both lateral surfaces = 2 x 44 = 88 (3)
Adding up (1), (2) and (3) gives us 146 m² as the total surface area
