Answer:

$\angle L = 52\\\\\angle J = 45\\\\\angle K = 83$

Step-by-step explanation:

$\angle J = \angle L-7\\\\\angle K=2\angle L-21\\\\\angle L = \angle L$

we know that

$\angle K +\angle J + \angle L =180$ by the sum of interior angles of a triangle

so we have

$(\angle L -7)+(2\angle L -21)+(\angle L)=180$

we can simplify

$(\angle L + 2\angle L + \angle L)+(-7-21)=180\\\\4\angle L -28=180\\\\4\angle L=180+28\\\\4\angle L = 208\\\\\angle L = 52$

and now we find the other angles

$\angle J = \angle L -7\\\\=52-7\\\\=45$

$\angle K = 2\angle L -21\\\\=2(52)-21\\\\=104-21\\\\=83$

Which equation is quadratic in form?

densk [106]

A quadratic equation is written in the form $ax^{2} + bx + c = 0$

Looking at the second, third, and fourth options, we see that the highest powers are greater than two, which automatically disqualifies them from being quadratics (since the highest power in a quadratic is 2).

This makes the first option the correct choice since the expansion of the equation gives $2x^{2} + 28x + 61$

What is the missing number?

JulsSmile [24]

Answer:

y = 2^{x}

Step-by-step explanation:

Given the above data for x and y.

From the algebraic expression;

y = 2^{x}

We can deduce that the value of y is equal to two (2) raise to the power of x.

When x = 1, y = 2

y = 2^{x}

y = 2^{1}

y = 2

When x = 2, y = 4

y = 2^{x}

y = 2^{2}

y = 4

When x = 3, y = 8

y = 2^{x}

y = 2^{3}

y = 8

The above calculations can be used to determine the other values of y with respect to x.

Mrs. Simmons gave a history test worth 92 points. There were only two types of questions on it: 2-point true/false questions and

SVETLANKA909090 [29]

Answer:

There are 8 true/false questions and 26 fill-in-the-blank questions.

Step-by-step explanation:

Let "t" be the number of 2-point true/false questions and "f" the number of 5-point fill-in-the-blank questions.

Mrs. Simmons gave a history test worth 92 points. Symbollically,

2 t + 5 f = 92 [1]

There were a total of 34 questions in the test. Symbollicaly,

t + f = 34

t = 34 - f [2]

If we replace [2] in 1, we get

2 (34 - f) + 5 f = 92

68 - 2 f + 5 f = 92

3 f = 24

f = 8

We replace f = 8 in [2],

t = 34 - 8 = 26

There are 8 true/false questions and 26 fill-in-the-blank questions.

In logic, a condition that must be satisfied for a statement to be true, but does not in and of itself make it true. Sufficient

Archy [21]

Answer:

Correlation

Step-by-step explanation:

This can be explained if we consider the case of correlation as in correlation this condition can arrive where a statement should be satisfied to be true when does not in or make it true itself.

Correlation is indicative of the degree to which there is a fluctuation in one more varying values together. The increase or decrease in the value is indicated by the positivity or negativity of the correlation respectively where the correlation itself does not make it true or is true in itself.
sufficient and necessary conditions are fulfilled only when one value needs to be true or false for the other to be true or false respectively.

Causality also known as causation is the effectiveness or potency in which one process or a cause, leads to the generation of of another process or an effect, where cause and effect are partially dependent on each other.
