12 – 15x > 22

Suntract 12 from both sides:

12-15x-12 > 22-12

Simplify:

15x > 10

Multiply both sides by -1 (reverse the inequality):

(15x)(-1)<(10)(-1)

Simplify:

15x < -10

Divide both sides by 15:

15x/15 < -10/15

Simplify:

x < -2/3

Your Answer Is x < -2/3

plz mark me as brainliest :)

Answer:

x < [tex]\frac{-2}{3}[/tex]       OR       x < -0.67

Step-by-step explanation:

The first step is to subtract 12 from both sides, like so:

12 - 15x > 22

-12           -12

__________

-15x > 10

Then, divide both sides by -15:

-15x > 10

x > [tex]\frac{-10}{15}[/tex]

Simplify:

x > [tex]\frac{-2}{3}[/tex]

When you multiply/divide by a negative number, you must flip the sign around. In this case, we divided by a negative number:

x < [tex]\frac{-2}{3}[/tex]       OR       x < -0.67

Given:

The number of elevations in Death Valley National Park is given below:

Zabriskie Point = 648 feet

Stovepipe Wells = 0 feet

Furnace Creek = -178 feet

Badwater Basin = -282 feet

To find the difference between the elevation at Zabriskie Point and Furnace Creek.

Formula

So,

The difference between the elevation at Zabriskie Point and Furnace Creek = (648-(-178)) feet

= 648+178 feet

= 826 feet

Hence,

The difference between the elevation at Zabriskie Point and Furnace Creek is 826 feet.

The elevation difference between Zabriskie Point and Furnace Creek in Death Valley National Park is 826 feet, obtained by adding the positive elevations.

To find the difference between the elevation at Zabriskie Point and Furnace Creek in Death Valley National Park, follow these steps:

Use the formula for subtracting negative numbers:

Difference = Elevation at Zabriskie Point - (Elevation at Furnace Creek)

Given elevations:

Elevation at Zabriskie Point = 648 feet

Elevation at Furnace Creek = -178 feet

Substitute these values into the formula:

Difference = 648 - (-178) feet

Remember that subtracting a negative is the same as adding the positive:

Difference = 648 + 178 feet

Perform the addition:

Difference = 826 feet

Therefore, the difference between the elevation at Zabriskie Point and Furnace Creek is 826 feet.

Step-by-step explanation:

The area of triangle DEF cannot be determined without specific measurements for the base and height. To find the area of a triangle, use the formula \( \frac{1}{2} \times \text{base} \times \text{height} \), and be attentive to significant figures.

To determine the measure of the area of triangle DEF, we would need specific information about the dimensions of the triangle, such as the base and the height. Without this information or a corresponding figure provided in the question, we cannot calculate the area. However, I can guide you on how to calculate it once you have the necessary dimensions.

To calculate the area of a triangle, the formula is \( \frac{1}{2} \times \text{base} \times \text{height} \). For example, if you have a triangle with a base of 166 mm and a height of 930.0 mm, the area would be \( \frac{1}{2} \times 166 \text{mm} \times 930.0 \text{mm} \). Make sure to convert the measurements to the same units if they are not already, and pay attention to the proper number of significant figures in your final answer.

The value of expression 1/10.

Given that we need to solve expression 100% - 9/10,

To explain the calculation of "100% - 9/10," let's break it down step by step:

First, let's simplify the fraction 9/10. This fraction represents a ratio where the numerator (9) is the number of parts, and the denominator (10) is the total number of parts.

In this case, it means that we have 9 parts out of a total of 10 parts.

Next, we need to calculate the percentage equivalent of 9/10. To do this, we can multiply the fraction by 100.

So, 9/10 × 100 = 90%.

This means that 9/10 is equivalent to 90%.

Finally, we subtract 90% from 100%. Since 100% represents the whole or the entirety, subtracting 90% from it gives us the remaining percentage.

Mathematically, 100% - 90% = 10%

10% = 1/10

Therefore, 100% - 9/10 equals 10%.

To multiply the expression 6z^2 by the trinomial (7z^2+3z-2), distribute 6z^2 across each term in the trinomial to obtain 42z^4 + 18z^3 - 12z^2.

The student has asked to multiply the expression 6z2 by the trinomial (7z2+3z-2). To solve this problem, we'll apply the distributive property, which entails multiplying the term outside the parenthesis by each term inside the parenthesis.

Combine all the products to get the final expanded expression: 42z4 + 18z3 - 12z2.

The product of [tex]\(6z^2\)[/tex] and [tex]\(7z^2 + 3z - 2\)[/tex] is [tex]\(42z^4 + 18z^3 - 12z^2\)[/tex].

To multiply [tex]\(6z^2\)[/tex] by the trinomial [tex]\(7z^2 + 3z - 2\)[/tex], you need to distribute [tex]\(6z^2\)[/tex] to each term inside the parentheses. Here's how you can do it stepwise:

1. Multiply [tex]\(6z^2\)[/tex] by the first term of the trinomial [tex](\(7z^2\))[/tex]:

[tex]\[ 6z^2 \cdot 7z^2 = 42z^4 \][/tex]

2. Multiply [tex]\(6z^2\)[/tex] by the second term of the trinomial [tex](\(3z\)):[/tex]

[tex]\[ 6z^2 \cdot 3z = 18z^3 \][/tex]

3. Multiply [tex]\(6z^2\)[/tex] by the third term of the trinomial [tex](\(-2\))[/tex]:

[tex]\[ 6z^2 \cdot (-2) = -12z^2 \][/tex]

Now, combine these results:

[tex]\[ 6z^2(7z^2 + 3z - 2) = 42z^4 + 18z^3 - 12z^2 \][/tex]

So, the product of [tex]\(6z^2\)[/tex] and [tex]\(7z^2 + 3z - 2\)[/tex] is [tex]\(42z^4 + 18z^3 - 12z^2\)[/tex].

It is the number 3.              

Answer:

OC = 16.7 cm

OAB = 332.9 cm² (1d.p)

OABD = 589.9 cm²(1d.p)

ABD = 257.1 cm²

Step-by-step explanation:

It is given that OC is 90° perpendicular to the line AB. In order to find OC, you can use Trigonmoetric formula, cosθ = adj./hypo. :

cosθ = adj./hypo.

adj. = OC cm

hypo. = 26 cm

θ = 100° ÷ 2

= 50°

cos 50 = OC/26

OC = 26 cos 50

= 16.7 cm (1d.p)

Next, is to find the area of triangle OAB using A = (1/2)×a×b×sinc :

a = 26 cm

b = 26 cm

c = 100°

A = (1/2)×26×26×sin 100

=332.87 cm² (2d.p)

Then, find the area of sector OABD using A = (θ/360)×π×r² :

θ = 100°

r = 26 cm

A = (100/360)×π×26²

= 589.92 cm² (2d.p)

Lastly, to find the area of segment ABD, you can to substract the area of triangle from the area of sector :

A = 589.92 - 332.87

= 257.1 cm² (1d.p)
