Answer:

KL = 6.75cm

JL = 9.3cm

Step-by-step explanation:

SInce Angle DEF is similar to angle JKL.

Then;

DE/EF = JK/KL

Given

DE = 4cm

JK = 3cm

EF = 9cm

Substitute

4/9 = 3/KL

4KL = 27

KL = 27/4

KL = 6.75cm

Similarly

DF/EF = JL/KL

12.4cm/9 = JL/6.75

9JL = 12.4 * 6.75

9JL = 83.7

JL = 83.7/9

JL = 9.3cm

Answer: 14

Step-by-step explanation:

Answer: 120ft

Step-by-step explanation:

To work out the area of this composite shape you would have to work out the two shapes separately. The shape could be split into 2 rectangles.

The formula for the area of a rectangle is base x height.

So, to work out the area of the living room you have to do 15x7=105

Then to work out the area of the foyer, you would have to do 3x5=15

Because you want the area of both of the shapes together, you have to add the two areas of the rectangles together.

So 105+15=120

Answer:

7.75

Step-by-step explanation:

7 is a whole so stays as such, 1/4 is 0.25 so 3/4 is 0.75

-6y-12<12-4y

First, add 12 on both sides.

-6y<24-4y

Now add 4y on both sides.

-10y<24

Divide -10.

y<-2.4

Answer:

≈ 5.3 cm.

Step-by-step explanation:

If 1 cm. represents 75 km. then dividing that by 400 to get 5.3333.. or just 5.3, we can safely say that on a map, two towns that would be 400 km. apart, would only appear a bit over 5 cm. apart on a map!

Answer: C

Step-by-step explanation: you multiply all your numbers together to get 420 and then you divide by 2 because it is half of a rectangle to get 210.

Answer:

127.41ft^2

Step-by-step explanation:

Given data

DImension of the square

10ft by 10ft

The perimeter of the square is

=10+10+10+10

=40ft

Hence the amount of the fencing of the circle is 40ft

That is the circumference is 40ft

C=2πr

solve for r

40=2*3.14*r

40=6.28r

r= 40/6.28

r=6.37 ft

Area= πr^2

Area= 3.14*6.37^2

Area= 3.14*40.5769

Area= 127.41ft^2

Answer:

f(x) = 3x - 7

Step-by-step explanation:

Let the independent variable of a function is 'y' and dependent variable 'x'.

Therefore, function will be in the form of y = ax - b

Now statement given in the question states that "The output is 7 more than 3 times the input."

That means y is 7 less than 3 times of x.

y = 3x - 7

Rewrite this equation in the form of a function.

f(x) = 3x - 7

Answer:

[tex]\huge\boxed{\sf x - intercept = ( 1 , 0 )}[/tex]

Step-by-step explanation:

x-intercept is the point at which the function crosses x and y becomes zero at that point.

So, y = 0

The point at which y = 0 in the given graph is when x = 1.

Hence,

x - intercept = ( 1 , 0 )

120l NaBr solute is saturated at 70 degrees. In this case option b is correct when  saturated at 70 degrees.

NaBr is the chemical formula for sodium bromide. It is an inorganic compound composed of sodium (Na) and bromine (Br). Sodium bromide is a white, crystalline solid that is highly soluble in water.

In terms of its properties and uses, sodium bromide has various applications. It is commonly used in the pharmaceutical industry as a sedative and anticonvulsant drug. Sodium bromide is also used in the oil and gas industry as a completion fluid in well drilling and workover operations. Additionally, it finds applications in photography as a component of some film developers.

As a salt, sodium bromide dissociates into sodium ions (Na+) and bromide ions (Br-) when dissolved in water. These ions can participate in various chemical reactions and have different effects depending on the specific application or purpose.

Answer:

9 / 13

Step-by-step explanation:

From the question :

Let :

Hostel students = h

Day students = d

Students with A grade = a

P(h) = 60% = 0.6

P(d) = 40% = 0.4

P(hostel with A grade) ; P(A / H) = 0.3

P(day with A grade) ; P(A / D) = 0.2

The probability that a student picked at random withbA grade is an hostel student is given as :

Probability of being an hostel student gun he has A :

P(H | A) = (P(A/H) * P(H)) ÷ P(A/H) * P(H) + P(A/D) * P(D))

P(H | A) = (0.3 * 0.6) ÷ ((0.3*0.6) + (0.2*0.4))

P(H | A) = 0.18 ÷ (0.18 + 0.08)

P(H | A) = 0.18 ÷ 0.26

P(H | A) = 9 / 13
