The four-sided geometric figure pictured is called a parallelogram. One feature of parallelograms is that opposite sides have eq

ual lengths. The dotted line splits the parallelogram into two triangles. What is true about the congruency of the two triangles? 1)More information is needed. 2)The triangles can be proven congruent using SSS. 3)The triangles can be proven congruent using HL. 4)The triangles are not congruent.

Answer:

The answer is the option 2

The triangles can be proven congruent using SSS

Step-by-step explanation:

we know that

The property of a parallelogram are the following

a) Opposite angles are congruent

m

b) Consecutive angles are supplementary

m

c) The diagonals of a parallelogram bisect each other

d) Opposite sides are parallel and congruent

AD=BC, AB=DC

see the attached figure to better understand the problem

Remember that

If two triangles are congruent by SSS

then

their corresponding sides are congruent

In this problem

the triangles ABD and CDB are similar by SSS

because

AD=BC, AB=DC -----> Opposite sides are congruent

How much chromium-51 will be left after 7 months?
Makovka662 [10]

Answer:

It seems there's more information in you question that you haven't posted.

7 months = 7 * (365/12) = 213 days

The half-life of chromium 51 is 27.7 days.

After 7 months, chromium 51 will have undergone 7.69 half-lives.

To solve for the ending amount we'll use the formula:

Ending Amount = Beginning Amount / 2^n where 'n' = # of half-lives

We'll say the beginning amount =1

Ending Amount = 1 / 2^7.69

Ending Amount = 0.0048426082

Basicaly if you started with 1 gram of chromium 51, after 7 months you would have 0.0048426082 grams.

a system of equations is shown below: equation a: 2c = d − 8 equation b: c = 3d 8 which of the following steps should be perform
Fofino [41]
If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:

equation a: 2c = d - 8      /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5

<span>The correct result would </span>be: <span>multiply equation a by −3.</span>

You need a 75 % alcohol solution. On hand, you have a 260 mL of a 30% alcohol mixture. You also have 95 % alcohol mixture . How
user100 [1]

30 \: percent \: alcohol \: in \: 260 \: ml \\ alcohol = 0.3 \times 26 0= 78 \: ml

c( \gamma ) =  \frac{78 +  0.95\gamma }{260 +  \gamma }  \times 100

c( \gamma ) = 75

\frac{78 +  0.95\gamma }{260 +  \gamma }   = 0.75

78 +  0.95\gamma  = 0.75 \gamma  + 195 \\ 0.2 \gamma  = 117 \\  \gamma  = 585

we \: need \: 585 \: ml \: of \: 95% \: alcohol

(NEED HELP ASAP) What is the value of S4 for
Alexandra [31]

Answer:

90

Step-by-step explanation:)

To obtain S_{4} , sum the first 4 terms, using n = 1 to n = 4

S_{4}

= 6(2)^{0} + 6(2)^{1} + 6(2)² + 6(3)³

= (6 × 1) + (6 × 2) + (6 × 4) + (6 × 8)

= 6 + 12 + 24 + 48

= 90
