Solve 4(x-3)-2(x-1)>0

Answer:

I think the answer is 43

Step-by-step explanation:

Because b=83

The total value of triangle angles =180

So 54+83=137

180-137=43

Answer:

[tex](r^{2*3/3^1^* ^ 3)[/tex]

Step-by-step explanation:

Given

[tex](r^2/3)^3[/tex]

Required

Determine the equivalent expression

[tex](r^2/3)^3[/tex]

Apply the following law of indices:

[tex](a^n)^m = a^m^n[/tex]

[tex](r^2/3)^3[/tex]

[tex](r^2/3^1)^3[/tex]

So, the expression becomes:

[tex](r^{2*3/3^1^* ^ 3)[/tex]

Option D answers the question.

I can only help you with the first one, because I'm new to geometry, but here it is:

Area: 91cm

Perimeter: 136cm You need to add all the side measures together.

Circumference: It isn't possible to find circumference unless it is a circular shape. So there is no circumference for this shape.

I hope this helps!

Answer:

20 inches tall

Step-by-step explanation:

If 1 inch equals 1 meter and 1 teaspoon equals 1,000 gallons of water, the model would have to be 20 inches tall to hold a volume of 20,000 gallons of water.

Answer:

D) Distribute Property

Step-by-step explanation:

The student did Distribute property but they didn't mark it down.

The inequality that describes the possible values of the expression is:

[tex]0 < \frac{b}{3a} - \frac{a}{3b} < \frac{9}{60}[/tex]

The expression is given by:

[tex]\frac{b}{3a} - \frac{a}{3b}[/tex]

To find the lower bound, we try to see when the expression is negative, hence:

[tex]\frac{b}{3a} - \frac{a}{3b} < 0[/tex]

[tex]\frac{b}{3a} < \frac{a}{3b}[/tex]

Applying cross multiplication and simplifying the 3's, we have that:

[tex]b^2 < a^2[/tex]

From the bounds given, this expression will never be true, at most they can be equal, when:

a = b = 4.

Hence the lower bound of values of the expression is of 0.

The expression is a subtraction, hence we want to maximize the first term and minimize the second.

Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:

Then:

[tex]\frac{b}{3a} - \frac{a}{3b} = \frac{5}{12} - \frac{4}{15} = \frac{25 - 16}{60} = \frac{9}{60}[/tex]

Hence the bounds are:

[tex]0 < \frac{b}{3a} - \frac{a}{3b} < \frac{9}{60}[/tex]

Answer:

They are parallel, they will never intersect.

Step-by-step explanation:

Notice that they have exactly the same steepness, which means their slopes are identical. The only difference between the two lines is the y-intercept. If we shifted one line vertically toward the y-intercept of the other, they would become the same line.

Answer:

  19 mL

Step-by-step explanation:

You want the volume of a rock with density 45 g/mL and mass of 855 g.

The units of density are mass per volume, so we can find the volume by dividing the mass by the density. The units basically tell you how to work the problem.

  [tex]\dfrac{855\text{ g}}{45\text{ g/mL}}=\dfrac{855}{45}\,\dfrac{\text{g$\cdot$mL}}{\text{g}}=\boxed{19\text{ mL}}[/tex]

Additional comment

Sometimes we like the volumes of things that aren't liquid to be expressed in cubic units. 1 mL = 1 cm³, so the volume could be described as 19 cm³.

Answer:

(x = 4, x = 4)

Step-by-step explanation:

Gonna solve it but you need to do the rest, the answers are all in the solution.

Expand the following:

(3 (x + 2) = 18, 3 x + 6 = 18)

3 (x + 2) = 3 x + 3 2:

((3 x + 3 2) = 18, 3 x + 6 = 18)

3×2 = 6:

(3 x + 6 = 18, 3 x + 6 = 18)

Subtract 6 from both sides:

(3 x + (6 - 6) = 18 - 6, 3 x + 6 = 18)

6 - 6 = 0:

(3 x = 18 - 6, 3 x + 6 = 18)

18 - 6 = 12:

(3 x = 12, 3 x + 6 = 18)

Divide both sides of 3 x = 12 by 3:

((3 x)/3 = 12/3, 3 x + 6 = 18)

3/3 = 1:

(x = 12/3, 3 x + 6 = 18)

The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

(x = 4, 3 x + 6 = 18)

Subtract 6 from both sides:

(x = 4, 3 x + (6 - 6) = 18 - 6)

6 - 6 = 0:

(x = 4, 3 x = 18 - 6)

18 - 6 = 12:

(x = 4, 3 x = 12)

Divide both sides of 3 x = 12 by 3:

(x = 4, (3 x)/3 = 12/3)

3/3 = 1:

(x = 4, x = 12/3)

The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

Answer:  (x = 4, x = 4)

Answer:

(B) $1470

Step-by-step explanation:

Given that the principal initial amount, p=$1200

Rate of simple interest per year, r=4.5% = 0.045

Time, t=5 years

Interest after 5 years,

I=prt= 1200 x 0.045 x 5 = 270

Total amount = Principal initial amount + Interest

=1200+270=1470

So, the total amount of the student's savings after 5 years is $1470.

Hence, option (B) is correct.

Answer:

10x + 15y ≥ 900

Step-by-step explanation:

She burns 10 calories per minute while biking and 15 calories per minute while running. For each exercise, the number of minutes multiplied by the number of calories burned per minute will give the total number of calories burned.

Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).

The inequality that models this situation is therefore

10x+15y≥900

The required inequality that models the given situation is 10x + 15y ≥ 900.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

While biking, she burns 10 calories per minute, and 15 calories per minute while running. The total number of calories burned for each exercise is the number of minutes multiplied by the number of calories burned per minute.

Let x be the number of minutes she spends biking and let y be the number of minutes she spends running.

Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).

As per the given situation, the required inequality would be as:

⇒ 10x + 15y ≥ 900

Thus, the required inequality that models the given situation is 10x + 15y ≥ 900.

When Abby's walk to Trout Street is 800 yards.

Distance is referred to as the length of a moving particle's real path. The shortest distance between a body's initial and final positions is referred to as displacement.

The distance between the segment and bottom right vertex is 800 yards.

The 1st street, Trout Street, and Salmon Street intersect at a point G.

Now, Trout street and Salmon street are at the same distance from the boardwalk.

From the figure, the distance between the boardwalk and salmon street is 800 yards.

Now the 1st street is perpendicular to line AE which is the distance between Trout street and Salmon street and hence AC = CE.

Therefore, When Abby's walk to Trout Street from the boardwalk is 800 yards.
