How do you prove SSS and SAS?

Answer:

22 students

Step-by-step explanation:

Create a system of equations where p is the number of students that voted for Patrick, and b is the number that voted for Britney

p + b = 100

b = p + 56

Solve by substitution by plugging in p + 56 as b in the first equation

p + b = 100

p + p + 56 = 100

Solve for p:

2p + 56 = 100

2p = 44

p = 22

So, 22 students voted for Patrick

Patrick sold 22 ballots.

22+56=78

22+78=100

Answer:

(√50+15/2)/2=√50/2+15/4=7.28

√8+4=6.82

π+4=7.14

13√80/16=7.26

3π-2=7.424

√30+1.8=7.277

Step-by-step explanation:

√30+1.8 is nearly equal to√30+1.8&13√80/16

so

√30+1.8& 13√80/16 can be apply.

Answer:

-1/5

Step-by-step explanation:

I couldn't tell whether or not your question was asking for either the slope intercept form or just the slope.

Your answer would be: y = -1/5x + 3   [if your question is asking for the slope intercept form]

OR

Your answer would be: -1/5   [if your question is asking for just the slope]

Answer:

There are 47 Borogroves and 35 Mome raths

Step-by-step explanation:

Here, given the number of legs, we want to find the number of each type of animals

Let the number of borogoves be b and the number of mome raths be m

From the question, there are 82 creatures;

Thus;

m + b = 82 ••••••••(i)

the total number of legs by b borogroves will be b * 2 = 2b

the total number of legs by m mome raths will be m * 4 = 4m

the sum of all legs is 234

2b + 4m = 234 •••••••••(ii)

From equation 1, m = 82-b

Substitute this into equation ii

2b + 4(82-b) = 234

2b + 328 - 4b = 234

4b-2b = 328-234

2b = 94

b = 94/2

b = 47

Recall;

m + b = 82

m + 47 = 82

m = 82-47

m = 35

Answer:

4ˣ + 4⁻ˣ es igual a 7

Step-by-step explanation:

4ˣ + 4⁻ˣ

Dónde;

2ˣ + 2⁻ˣ = 3

Nosotras tenemos

[tex]2^x + \dfrac{1}{2^x} = 3[/tex]

[tex]2^{2\cdot x} +1 = 3 \cdot 2^x[/tex]

[tex]2^{2\cdot x} - 3 \cdot 2^x +1 = 0[/tex]

Deje que 'a' represente 2ˣ, tenemos;

a² - 3·a + 1 = 0

a = (3 ± √(3² - 4 × 1 × 1))/2 = (3 ± √5)/2

∴ a = 2ˣ = (3 ± √5)/2

((3 ± √5)/2)^2 - 3×(3 ± √5)/2 + 1

x = ln(3 ± √5)/2/(ln(2))

4ˣ + 4⁻ˣ = 4^(ln((3 ± √5)/2)/(ln(2))) + 4^(-(ln((3 ± √5)/2)/(ln(2)))) = 7

∴ 4ˣ + 4⁻ˣ = 7.

Answer:

A = 63.59

C = 28.26

Step-by-step explanation:

r = 4.5

Area of a circle:

A = πr²

A = 3.14(4.5²)

A = 3.14(20.25)

A = 63.59

Circumference:

C = 2πr

C = 2(3.14)(4.5)

C = 28.26

Answer:138

Step-by-step explanation:

I just took the test

The number of people who score 90 or less is 138, option B is correct.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Let us find the proportion of people in the group of 400 who score 90 or less on the memory test.

Given that the scores are normally distributed with a mean of 100 and a standard deviation of 25.

Using a z-score table, we can find the z-score corresponding to a raw score of 90 as follows:

z = (90 - 100) / 25 = -0.4

The area under the standard normal distribution curve to the left of z = -0.4 is 0.3446, which represents the proportion of people who score 90 or less on the memory test.

Therefore, the number of people who will score 90 or less is:

0.3446 x 400 = 137.84

Hence, the number of people who score 90 or less is 138, option B is correct.

Answer:

100

Step-by-step explanation:

20/2= 10 and 10 squared is 100 but you have to move the -6 to the opposite side

The number required to add to the equation x² + 20x - 6 is 106

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A =  x² + 20x - 6 = 0

Now , to make the equation as a perfect square,

The number to be added to the equation is 106

Adding 106 to the equation , we get

A =  x² + 20x - 6 + 106

On simplifying the equation , we get

A =  x² + 20x +100

Now , the equation can be factorized as

A = ( x + 10 )²

A = 0

( x + 10 )² = 0

x = -10

Hence , The number required to add to the equation x² + 20x - 6 is 106 to make it a perfect square

The constant of proportionality of 100 cm in 1 meter is 0.01

The statement is given as:

100 cm in 1 meter

Rewrite as:

x cm in y m

Express as ratio

100 : 1 = x : y

Express as fraction

100/1 = x/y

Divide

100 = x/y

Make y the subject

y = x/100

Divide

y = 0.01x

A direct proportion is represented as y = kx

Where k represents the constant of proportionality.
