Based on the karats on the gold necklace, the weight in grams of the pure gold in the necklace is B. 40.5 grams

When something is said to be 18 karats of gold, it means that there is about 75% pure gold and then 25% of other materials.

If the necklace has 75% gold, the pure gold in grams is:

= 75% x 54

= 40.5 grams

In conclusion, the pure gold weighs 40.5 grams.

When two angles are vertical angles, then they are congruent, the hypothesis of the conditional is that D. Two angles are vertical angles.

When two lines cross at a point, vertical angles are created. They are always on an equal footing. In other words, four angles are created anytime two lines cross or intersect. It is evident that two opposed angles are equal and are referred to as vertical angles.

It should be noted that if p and q are statements, the conditional of q by p is “if p then q” denoted p → q. We call p the hypothesis of the conditional and q the conclusion.

Therefore, if two angles are vertical angles, then they are congruent, the hypothesis of the conditional is that the two angles are vertical angles.

If Ian wants to get an expected quiz score of 83, then he needs to spend 3.33 hours in homework that week.

We know that the situation is modeled by the linear equation:

y = 60+ 6.9x

Where y represents the expected quiz score and x the hours spend on homework that week.

If we define y = 83, the value of x will be the number of hours that the students need to do homework such tath the expected quiz score is 83.

Solving the linear equation:

83 = 60 + 6.9*x

(83 - 60)/6.9 = x

23/6.9 = x

3.33 = x

So to get an expected quiz score of 83, they need to spend 3.33 hours in homework that week.

Answer:

3x² + 24x + 36 = 0

Step-by-step explanation:

A quadratic equation has the standard form ax² + bx + c = 0.
a, b and c are constants.

The roots of a quadratic equation represent the two solutions to the quadratic equation

Given that the roots are -2 and -6 we have

x = -2 and x = -6 as the solutions

Add 2 to both sides of x = -2 ==> x + 2 = 0
Add 6 to both sides of x = -6 ==> x + 6= 0

So (x+2)(x+6) = 0 is the factored representation of this equation. We have to multiply by a leading coefficient of 3

So the quadratic equation is
3(x+2)(x+6) = 0

Using the FOIL method
(x + 2)(x + 6) = x² + 6x + 2x + 12 = x² + 8x + 12

The leading coefficient is the coefficient of x² and is given as 3

So the quadratic equation in standard form is
3(x² + 8x + 12) = 0

==>  3x² + 24x + 36 = 0

If you solve this equation on a quadratic equation calculator you will get the solutions x = -2 and x=-6

x% of 6 plus y% of 6 can be expressed as x + y = 1.83.

A percentage is a quantity or ratio that is expressed as a fraction of 100. The symbol "%" is used to denote percentage. The percentage is denoted by the abbreviations "pct" or "pc". In other words, the percentage is measured in terms of 100 and is defined as the amount of one quantity that is made up of another.

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

The sum of x% of 6 and y% of 6 is 11%.

Therefore,

x% of 6 + y% of 6 = 11%

x% × 6 + y% × 6 = 11%

[tex]\frac{x}{100} \times 6 + \frac{y}{100} \times 6 = \frac{11}{100}[/tex]

Taking [tex]\frac{6}{100}[/tex] common.

[tex]\frac{6}{100}(x+y)=\frac{11}{100}[/tex]

6( x + y ) = 11

Dividing each side by 6.

[tex]x + y = \frac{11}{6}[/tex]

x + y = 1.83

Therefore, the equation x + y = 1.83 expresses the statement x% of 6 plus y% of 6.

Answer:

It is an acute angle

Step-by-step explanation:

You can tell by looking at it that it is less than 90 degrees, making it an acute angle.

The line in standard notation is 2y - 7x = 7 and in slope-intercept form it is:

y = (7/2)*x + 7/2

We want our line to be perpendicular to 2x + 7y = 1

Rewriting that line, we get:

y = (1 - 2x)/7 = 1/7 - (2/7)*x

So the slope is (-2/7), then the slope of a perpendicular line is 7/2.

So our equation is something like:

y = (7/2)*x + b

To find the value of b we replace the values of the point (1, 7), it gives:

7 = (7/2)*1 + b

7 = 7/2 + b

7 - 7/2 = b

7/2 = b

Then the linear equation in slope-intercept is:

y = (7/2)*x + 7/2

And the standard form is:

y - (7/2)*x = 7/2

2y - 7x = 7

As per the question statement, we are required to determine the options from the given four, which are the best possible matches to being benefits of consumer program.

To solve this question, we will check for the possibility of every option by logical reasoning.

Option (A) is "They help prosecute company’s that sell unsafe products" which is true, and thus protects the consumer against frauds or exploits and health issues. Hence, this is definitely a benefit of consumer program.

Option (B) is "They’re funded by taxpayers not consumers" which is illogical because taxpayers are the consumers themselves. Hence, this is not a benefit of consumer program.

Option (C) is that "They help maintain industry standards by issuing professional licenses" which is false because forum has nothing to do with issuing licenses; It ensures that consumers are served with best quality products at the best prices and takes legal action against fraudulency. Hence, this is not a benefit of consumer program.

Finally, Option (D) is that "They help consumers identify the best product reviews from various sources" which is true. Hence, this is definitely another benefit of consumer program.

The solution for the inequality is given by: -1  < m < 2 .

In mathematics, an inequality is a link that compares two numbers or other mathematical expressions unfairly. Size comparisons between two numbers are commonly made on the number line. Various types of inequalities can be represented using various notations, such as:

a is smaller than b, as shown by the symbol a<b.

When the expression a > b is employed, it means that an is larger than b.

In no circumstance is a the same as b. These relationships are referred to as strict inequalities since a is strictly less than or strictly greater than b. Equivalence isn't taken into account.

The given inequality is of the form:

−15+ 6 |2m − 1| < 3

Now let us solve the inequality :

or ,  6 |2m − 1| < 3 + 15

or ,  6 |2m − 1| < 18

or,  |2m − 1| < 3

or, -3 < 2m-1 < 3

or, -3+1 < 2m < 3 + 1

or, -2 < 2m < 4

or, -1 < m < 2

For the given right triangle, the tangent of theta is equal to 4/3 so the correct option is D.

Here we have a right triangle, and we want to find the tangent of one shown angle.

Remember that the trigonometric relation for a tangent is:

tan(a) =(opposite cathetus)/(adjacent cathetus).

On the image, we can see that the adjacent cathetus to the given angle has a measure of 6 units, while the opposite cathetus has a measure of 8 units, then we can replace that in the general relation to write:

tan(θ) = 8/6

Now we just can simplify that fraction if we divide both numerator and denominator by 2, we will get:

tan(θ) = 8/6 = 4/3

Then we conclude that the correct option is D.

Using proportions, it is found that:

3. Due to the lower cost per pound, the twelve-pack is the better value.

4. Due to the lower cost per cup, the Pacific Coast Coffee is the better value.

5. Lettuce and Asparagus cost the same per pound.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For item 3, the cost per pound is the proportion of the cost by the weight, hence:

Due to the lower cost per pound, the twelve-pack is the better value.

For item 4, we follow the same procedure, hence:

Due to the lower cost per cup, the Pacific Coast Coffee is the better value.
