Answer 2

Another way to write Brett’s total number of points on the test is 35(2) - 1/2(15).

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Brett took a test in which 2 points were earned for each correct response and -1/2 point was earned for each incorrect response.

From the data given in the question:

= 35(2) - 1/2(15)

= 35(2) + [-1/2(15)]

Another way to write Brett’s total number of points on the test:

= 35(2) - 1/2(15)

Thus, another way to write Brett’s total number of points on the test is 35(2) - 1/2(15).

Write a trinomial of degree 35

Answers

we,know that
Trinomial of degree 35 means a polynomial that 
a) Having tree terms
b) Highest degree 35
The degree of a polynomial is the highest value of the exponent in the expression

examples
x³⁵ + 5x³ + 8
t³⁵ + 3t - 2
y³⁵ + y² + 6
There are many possible solutions.
Let's understand the concept first.

The degree of a polynomial is determined based on the highest exponent (power) in the equation. This means that a polynomial of the 35th degree would be be having 35 as the highest power

A trinomial is a polynomial having 3 terms in it. Terms are separated by addition or subtraction operations only.

We want to write a trinomial of degree 35.
Based on the above explanations, the following could be valid equations:
x³⁵ + 3x²⁰ + 9x
27a + 3a³⁵ + 90

Answers

The correct answer is 126 in^2. If you don't know how I got that please comment and I will clarify.
to find the are of a trapezoid, it is 0.5(base 1 plus base 2)height. so base 1 is 16 inches and 2 is 12, so 16+12is 28, and 28/2 is 14, the height is 9, so 9*14 is the answer. 90+36 is 126. so 126 in^2

One year, a student council sold 856 copies of a school yearbook. Four fifths of the students at school bought a copy. How many students did not buy a yearbook?

Answers

214 students didn't buy the yearbook. I solved this answer by dividing 856 by 4 and I got 214 which means every 1/5 is 214 students

By solving the equation 4/5 * x = 856, we find that the total number of students at the school is 1070. Calculating the remaining one fifth, we determine that 214 students did not buy a yearbook.

The student's question asks us to find out how many students did not buy a yearbook if four fifths of the students at school did buy one. To solve for this, we need to first determine the total number of students and then calculate the remaining one fifth who did not purchase the yearbook.

Let x represent the total number of students at the school. Since 856 copies of the yearbook were sold and this represents four fifths, we can set up the equation:

4/5 * x = 856

To find x, we divide both sides of the equation by 4/5, which is equivalent to multiplying by the reciprocal (5/4):

x = 856 * 5/4

x = 1070

Thus, the total number of students at the school is 1070. To find out how many did not buy the yearbook, we take the remaining one fifth:

1/5 * 1070 = 214

Which equation represents the following word sentence? Five more than three times x is twenty. 5x + 3 = 20 3x + 5 +20 3(x + 5) = 20 3x + 5 = 20 Description

Answers

Final answer:

The equation that represents the word sentence 'Five more than three times x is twenty' is 3x + 5 = 20. To solve this equation, subtract 5 from both sides and divide both sides by 3 to find the value of x.

Explanation:

The equation that represents the word sentence 'Five more than three times x is twenty' is 3x + 5 = 20.

In this equation, '3x' represents three times x, and '5' represents five more than that. The equation states that the sum of three times x and five is equal to twenty.

To solve this equation, you can subtract 5 from both sides to isolate '3x', and then divide both sides by 3 to find the value of x.

V = 1/3 HS^2 

Using opposite operations, rewrite the equation so s2 is on one side of the equation by itself.

Answers

V=1/3 HS²
Solving for S².
Multiply both sides by 3.
3V= 3 x 1/3 HS²
3V=HS²
Divide both sides by H.
3V/H=HS²/H
3V/H=S²
Switch sides
S²=3V/H

Answer: S² = 3V / H

Final answer:

To solve for S² in the equation V = 1/3 HS², multiply both sides by 3 and then divide by H, resulting in S² = 3V / H.

Explanation:

To rewrite the equation V = 1/3 HS² so that S² is by itself on one side of the equation, we need to use opposite operations.

We start by multiplying both sides of the equation by 3 to eliminate the fraction on the right side:

3V = HS²

Next, we divide both sides by H to solve for S²:

S² = 3V / H

Now, S² is by itself on one side of the equation, which is the desired outcome.

Segment AD is parallel to segment BC, and segment AB is parallel to segment CD. Which statement about the measure of ∠D is NOT true?

Answers

Final answer:

An incorrect statement about the measure of ∠D would be that it is supplementary to or equal in measure to ∠B, as that conflicts with the properties of a parallelogram where opposite angles are equal and adjacent angles are supplementary.

Explanation:

Given that segment AD is parallel to segment BC, and segment AB is parallel to segment CD, we are dealing with a situation where AD and BC form one pair of parallel lines, and AB and CD form another. This would typically describe a parallelogram, where opposite sides are equal in length and opposite angles are equal in measure.

One statement about the measure of ∠D that is NOT true might suggest that ∠D equals the angles adjacent to it, which would conflict with the properties of a parallelogram. Instead, the measure of ∠D should equal the measure of ∠B, and the angles adjacent to ∠D (∠A and ∠C) should be supplementary to ∠D as they form a linear pair with ∠B and ∠D, respectively.

Therefore, without knowing the exact degrees, the incorrect statement could be that ∠D is supplementary to ∠B (adds up to 180 degrees) or that it is equal in measure to adjacent angles ∠A or ∠C, both of which are false in the context of parallelogram properties.

Final answer:

The measure of ∠D is equal to ∠A.

Explanation:

The statement that is not true about the measure of ∠D is that line B is a decreasing line while line A is an increasing line, with line B being much steeper than line A.

The given information tells us that segment AD is parallel to segment BC, and segment AB is parallel to segment CD. These parallel lines create a series of congruent angles.

Since AD is parallel to BC, the corresponding angles ∠A and ∠D are congruent. Similarly, since AB is parallel to CD, the corresponding angles ∠B and ∠C are congruent as well. Therefore, the measure of ∠D is equal to ∠A.

Matt has 75 hundredths of a dollar. Kendra has 7 tenths of a dollar. Who has more money?

Answers

Answer:

matt

Step-by-step explanation:

Matt has 75 hundredths of a dollar ($0.75) while Kendra has 7 tenths of a dollar ($0.70). Matt has more money as $0.75 is greater than $0.70.

In this scenario:

Matt has 75 hundredths of a dollar, which is equal to $0.75.

Kendra has 7 tenths of a dollar, which is equal to $0.70.

To determine who has more money, compare $0.75 and $0.70. Clearly, Matt has more money since $0.75 is greater than $0.70.

The chart shows the path reactants take to become products.

Which statement best describes the chart?
A. Heat was removed from the activation energy to create the product.
B. Heat was added to create the product.
C. The products have less energy than the reactants.
D. The products have the same energy as the reactants.

Answers

From the graph, we see that the final position of the curve is higher than the original height of the curve, meaning the products have more energy than the reactants.

Hence energy was added for the reactants to become the products.  This is why the reaction is endothermic, because the products retained some of the supplied energy.

Part of the energy supplied was used to overcome the activation energy (the peak of the curve).  However, this extra energy is recuperated as heat once the product is formed.

Answer: the answer is heat was added to create the product.

Maurice receives $3 per week for allowance and earns an additional $1.75 for each chore he completes. Write an equation to find t, the total amount earned for c chores in one week.

Answers

He receives 3 dollars per week as allowances and an additional 1.75 dollars for each chore done by him.

His total earnings in one week would be sum of his allowances and chores that he complete in one week.

Here 't' represents total earnings and 'c' represents number of chores that he completed in one week.

Total Earnings = Allowances + (compensation of one chore)*(Number of chores)

Mathematically, it can be written as :-

t = 3 + 1.75c

Hence, (t = 1.75c + 3) is the required equation.
