Answer:

lesser x = - 1 , greater x = 1

Step-by-step explanation:

- 4x² - 7 = - 11 ( add 7 to both sides )

- 4x² = - 4 ( divide both sides by - 4 )

x² = 1 ( take square root of both sides )

x = ± [tex]\sqrt{1}[/tex] = ± 1

then

lesser x = - 1

greater x = 1

Answer:

  n ≥ 7

Step-by-step explanation:

The English descriptor "is at least" corresponds to the math relation "is greater than or equal to." In symbols, we have ...

  "n is at least 7"   ⇔   n ≥ 7

Answer:

n ≥ 7

Step-by-step explanation:

If the question states "at least 7", it means the inequality should include 7 and the rest of the values lying in the set of the inequality are greater than 7 as 7 is the least value.

The measure of angle L is 52

Step-by-step explanation:

Mathematically, in a triangle, the sum of the angles equal 180

So in this case;

J + K + L = 180

So therefore;

8x + 6 + 2x + 2 + 4x + 4 = 180

8x + 2x + 4x + 6 + 2 + 4 = 180

14x + 12 = 180

14x = 180 -12

14x = 168

x = 168/14

x = 12

So to get the measure of angel L, we simply substitute the value x in the equation for L

From the question, L = 4x + 4

So therefore L = 4(12) + 4 = 48 + 4 = 52

Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

If in ΔHIJ, m∠H = x - 1, m∠I = 2x + 5, and m∠J = 7x + 6.

The value of x is  17.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

Example:

Triangle ABC:

m∠A + m∠B + m∠C = 180

We have,

ΔHIJ

m∠H = x - 1

m∠I = 2x + 5

m∠J = 7x + 6

We know that,

The sum of the angles of the triangle is 180 degrees.

m∠H + m∠I + m∠J = 180

(x - 1) + (2x + 5) + (7x + 6) = 180

x - 1 + 2x + 5 + 7x + 6 = 180

10x + 10 = 180

Take 10 common.

10 (x + 1) = 180

Divide both sides by 10.

x + 1 = 180/10

x + 1 = 18

Subtract 1 on both sides.

x = 18 - 1

x = 17

Thus,

If in ΔHIJ,

m∠H = x - 1

m∠I = 2x + 5

m∠J = 7x + 6.

The value of x is  17.

Using it's concept, it is found that the absolute deviation of 30 in the data set is of 2.

The absolute deviation of a measure is given by the absolute value of the differente between the measure and the mean.

The mean is the sum of all observations divided by the number of observations. In this data-set, it is given by:

M = (26 + 35 + 27 + 30 + 22)/5 = 28

30 - 28 = 2, hence, the absolute deviation of 30 in the data set is of 2.

Answer:

since the adjacent is given which is 6.3 and we are to solve for the hypotenuse, it's best to use Cos

since Cos(27°)=adjacent/hypotenuse

we can substitute in the values

therefore we have Cos(27°)=6.3/x

x=6.3/Cos(27°)

x=7.06...

rounding this to the nearest tenth will be 7.1

Answer:

$44.25

Step-by-step explanation:

($4.50×7)+(4.25×3)

=$31.50+$12.75

=$44.25

$44.25 is the cost if they bought 7 bags of popcorn and 3 drinks and 4.50p+4.25d is for p bags of popcorn and d drinks.

Two or more expressions with an Equal sign is called as Equation.

Given that

popcorn for $4.50

drink for $4.25.

There are 7 bags of popcorn and 3 drinks.

So let us find the total cost.

7(4.50)+3(4.25)

31.5+12.75

44.25

So $44.25 is the cost if they bought 7 bags of popcorn and 3 drinks

Now we need to find cost for p bags of popcorn and d drinks.

4.50p+4.25d

Hence $44.25 is the cost if they bought 7 bags of popcorn and 3 drinks and 4.50p+4.25d is for p bags of popcorn and d drinks.

Answer:

Step-by-step explanation:

well the area of a square is equal to the Width x Height. For example each side being 4 would be 4x4x4x4 or 4 to the second power.

Step-by-step explanation:

I will take long to answer this so i will give you the key to answering it.

Basically, since you know the sum of all the angles of a triangle equal 180, all you have to do is use 180 and subtract the numbers alredy there together to get the missing amount.

For example, to find out the answer to A, you already know two of the degree measurements which are 72 and 68. Now, subtract them with 180.

72+68=140

180-140=40

So, therefore, A equals 40 degrees.

I will give you one more example.

If you want to find the measurements of the angles B and C, the same process will happen. The only thing that is different is that only one known measurement is provided which is 36.5 but not so fast, they gave you a hint. That square above B. That means B is a right angle. So we got one measurement in the triangle, B is 90 degrees. Alright now continue like before.

90+36.5=126.5

180-126.5=53.5

Hope this helps.
