Hello friends,

Let x represent the start temperature.

Start with finding the total drop in temperature, 3 * 5 = 15.

Then subtract from the starting temperature, x - 15.

Final answer, x - 15.

Hope I helped :)

JL is a diameter of circle k. If tangents to circle I are constructed through points L and K what relationships would exist betw

luda_lava [24]

i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point. So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.
Remark. Draw a picture to check the

Out of 100 employees at a company, 92 employees either work part time or work 5 days each week. There are 14 employees who work

Alexus [3.1K]

Answer: 0.02

Step-by-step explanation:

OpenStudy (judygreeneyes):

Hi - If you are working on this kind of problem, you probably know the formula for the probability of a union of two events. Let's call working part time Event A, and let's call working 5 days a week Event B. Let's look at the information we are given. We are told that 14 people work part time, so that is P(A) = 14/100 - 0.14 . We are told that 80 employees work 5 days a week, so P(B) = 80/100 = .80 . We are given the union (there are 92 employees who work either one or the other), which is the union, P(A U B) = 92/100 = .92 .. The question is asking for the probability of someone working both part time and fll time, which is the intersection of events A and B, or P(A and B). If you recall the formula for the probability of the union, it is

P(A U B) = P(A) +P(B) - P(A and B).

The problem has given us each of these pieces except the intersection, so we can solve for it,

If you plug in P(A U B) = 0.92 and P(A) = 0.14, and P(B) = 0.80, you can solve for P(A and B), which will give you the answer.

I hope this helps you.

How much material is needed to construct a triangular tent that is 6 feet wide 4 feet tall and 8 feet long with side measurement

jonny [76]

Answer: 152ft^2

The amount of material needed to construct the tent is 152ft^2

Step-by-step explanation:

The amount of material needed to construct a triangular tent= the surface area of the triangular tent.

S.A = area of the 2 side rectangles + area of the 2 side triangles + area of the base.

S.A = Ab + At + Ar ....1

Area of the base Ab= Length × width = 8×6 = 48ft^2

Area of the two triangles At = 2 × 0.5 × width × height

At = width × height = 6×4 = 24ft^2

Area of the two rectangles Ar = 2 × side measurement × length

Side measurement is given as 5ft.

or it can be calculated using;

Side length can be calculated using Pythagoras theorem.

Examining the figure attached, we can see that;

Side breadth b = √(h^2 + (w/2)^2)

b = √(4^2 + (6/2)^2) = √(16+9) = √25

b = 5ft

Ar = 2×5×8 = 80ft^2

From eqn1, S.A can be solved as;

S.A = 48 + 24 + 80

S.A = 152ft^2

I will give brainliest if you answer this question!!

AnnZ [28]

A,C,D

"B" is definitely not the answer because the fraction isn't negative but the decimal is negative which isn't right.

Simplify the following radicals. 1. √16 2. √17 3. √18 4. √19 5. √20

Pavel [41]

Answer:

Step-by-step explanation:

$1) \sqrt{16}= \sqrt{4*4}=4\\\\\\2) \sqrt{17}$

This is the simplest form as 17 is a prime number.

$3) \sqrt{18}= \sqrt{2*3*3} = 3 \sqrt{2}\\\\\\4) \sqrt{19}$

19 is a prime number. so it is the simplest form.

$5) \sqrt{20}= \sqrt{2*2*5}=2 \sqrt{5}$
