PLEASE HELP!!!!

Quadrilateral ABCD is similar to quadrilateral EFGH. What is the value for x, the length
of side CD?
A-10
B-16
C-14
D-18

Answer:

Option C represents an exponential function

Step-by-step explanation:

Generally, we have an exponential function in the form ;

y = a.b^x

Where in fact, a is not 0

In this case, let us have a as 1 and b as 2

So we have;

for x = -1

y = 2^-1 = 1/2

for x = 0

y = 2^0 = 1

for x = 1

y = 2^1 = 2

for x = 2

y = 2^2 = 4

So the correct choice here is the third option

Answer:

What is the question?

Step-by-step explanation:

Answer: x ≥ -80

Step-by-step explanation:

-1/2x ≤ 40

1/2x ≤ -40

x ≥ -80

Answer:

39

Step-by-step explanation:

sqrt(39*13*13)

= sqrt(1521)

= 39

Answer: [tex]6351.25\ ft[/tex]

Step-by-step explanation:

Given

Angle of elevation [tex]x=12^{\circ}[/tex]

Height of tower [tex]h=1350\ ft[/tex]

Suppose tourist is d feet away from the tower

from the figure, we can write

[tex]\Rightarrow \tan 12^{\circ}=\dfrac{1350}{d}\\\\\Rightarrow d=\dfrac{1350}{\tan 12^{\circ}}=6351.25\ ft[/tex]

Thus, the distance of tourist from the tower is [tex]6350.25\ ft[/tex]

The answer is 1/10

This is simple division

The equation is (1/5÷2)

I did my work on a sheet of paper so i know i did this correctly

My explanation of my work:

Keep change flip is the operation used here

So you keep 1/5 ,change the division sign to multiplication and flip the 2/1 into 1/2 so the new equation is (1/5x1/2) the answer to that is 1/10  

Have an amazing day :)

LA = Use power rule which is "use to differentiate expressions". d/dL [L^n] = nL^n-1. A add all areas of the faces

SA = To find SA  do bh + 2ls + lb

Hope this helps you find your answer!

Answer:

The answer would be 6.

Step-by-step explanation:

First, we need to make equations for these electricians fee's.

Electrician one: Y=25x+50, 50 is the upfront cost and 25 is the cost per hour for work.

Electrician two: Y=27.50x+35, It is the same thing for these numbers.

Then you need to incert numbers into the X place. Y will be your answer.

Y=25(6)+50, Y=150+50, Y=200

Y=27.50(6)=35, Y=165+35, Y=200

The answer would be 6. If both the electricians worked for 6 hours each, their prices would be equal.

Answer:

20km

Step-by-step explanation:

we need to find c, which is the hypotenuse of the right triangle.

we know the lengths of the legs, which are given as 16km and 12km

you might notice that 16km and 12km can both be divided by 4, which will then give is 4 and 3.

3,4,5 is a pythagorean triple-(the sums of the squares of 3 and 4 is equal to the square of 5).

The triple can be proved:

3²+4²=5²

9+16=25

25=25

that means the lengths of the triangle is a multiple of the triple 3, 4, and 5

so that means that c is 5*something

since 12 and 16 are 3*4 and 4*4 respectively, that means that c must be 5*4=20km

Hope this helps!

Answer:

6% commission

Step-by-step explanation:

Exchange Rates

£1:$1.31

£1 : €1.14

$759.80 to pounds sterling :

£1 = $1.31

x = $759.80

Cross multiply :

x = 759.80 / 1.31

x = £580

£1 = €1.14

x = €342

Cross multiply :

x = 342 /1.14

x = £300

Total = £(580 + 300) = £880

Amount deducted = commision = £880 - £827.20 = £52.80

Percentage commission :

(52.80 / 880) * 100%

0.06 * 100%

= 6% commission

it's divergent, you can actually simplify this series by combining terms in pairs

Answer:

∡b = 53°

∡d = 127°

∡c = 127°

Step-by-step explanation:

in trapezoids, the two top angles are equal and the two bottom are equal

also, there are 360 degrees in any 4-sided polygon

53 + 53 + x + x = 360

2x + 106 = 360

2x = 254

x = 127

Answer:

127

Step-by-step explanation:

4x+4=6x-3

4=2x-3

7=2x

x=3,5

3x+2=17x-4

2=14x-4

6=14x

Answer:

2:6

Step-by-step explanation:

The question asks for the ratio of ladybugs to total insects. We'll use "l" for ladybugs and "i" for insects. So, the ratio will be l:i.

The number of ladybugs is 2, so we can plug that into our ratio.

2:i

Now, plug in the total number of insects, which is 6.
