Answer:
B
Step-by-step explanation:
Tickets for a school jazz concert were sold before the concert and at the door. After reviewing ticket sales, the band director found that 80 fewer tickets were purchased at the door than before the concert. A total of 520 tickets were sold. Let d represent the number of tickets sold at the door and b represent the number of tickets sold before the concert. Latifa wrote the following system of linear equations to find the number of each type of ticket sold:
d + b = 520. d minus 80 = b.
What is Latifa’s error?
Latifa should have written the first equation as d minus b = 520.
Latifa should have written the second equation as d + b = 80.
Latifa should have written the first equation as b + 80 = 520.
Latifa should have written the second equation as d + 80 = b.

Answer:
a = 98⁰
Step-by-step explanation:
According to the the triangle sum thereom, all angles in triangle add up to 180⁰.
m<a + m<b + m<c = 180⁰
m<a + 34⁰ + 48⁰ = 180⁰
m<a + 82⁰ = 180⁰
m<a + 82⁰ - 82⁰ = 180⁰ - 82⁰
m<a = 98⁰
Hope this helps, thank you :) !!

Answer:
125 in²676 km²20 square unitsStep-by-step explanation:
The Pythagorean theorem tells you the square on the hypotenuse is equal to the sum of the squares on the other two sides. (This is the version you use for problem 2.)
This also means the square on one side is the difference between the square on the hypotenuse and the square on the other side. (Use this version for problems 1 and 3.)
1. ? = 200 in² -75 in² = 125 in²
2. ? = 576 km² + 100 km² = 676 km²
3. ? = 36 square units - 16 square units = 20 square units
Tell whether the angles are adjacent or vertical then find the value of x

Let u = tan x.
Use power rule

round to the nearest hundredth 2.033
Answer:
2.03
Step-by-step explanation:
2.033
When you round to the nearest hundredth you look at the thousandths place and see if it is 5 or above. If it's 5 or above you round and change the hundredth place. ( 2.04 )
In this case it is lower than 5
So, it would be 2.03
Hope this helps dude
The round off the number 2.033 to nearest hundredth is 2.03.
What is Rounding off?Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. When the rounded number is increased, then the given number is said to be rounded up, conversely, if the rounded number is dropped, then it is said to be rounded down.
We have to round off the number 2.033 to nearest hundredth.
When rounding to the nearest hundredth, check the thousandths place to see if it is 5 or higher.
If it's 5 or higher, you go around and change the hundredth place 2.04.
But here it is less than 5 which makes the round off 2.03.

It should be noted that the quadrilateral is a trapezoid.
What's a trapezoid?A trapezoid is a quadrilateral with at least one pair of parallel sides. In a trapezoid, the parallel sides are called the bases, and the non-parallel sides are called the legs. The distance between the bases is known as the height or altitude of the trapezoid.
A trapezoid has two bases, which are parallel to each other. These bases can have different lengths or the same length, depending on the type of trapezoid.
The legs of a trapezoid are the non-parallel sides. They connect the bases and can have different lengths.
A trapezoid has four angles. The angles formed by the bases and legs are called the base angles, while the angles formed by the legs and non-adjacent side are called the diagonal angles.

If f(x) = 629x, what is f(0)?
Answer:
Since f′>0, f is strictly increasing, so if f(0)=0, you will have f>0 if x>0 and f<0 if x<0. There is no need to consider the second derivative.
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
because 629 × 0 = 0 then f(1) would be 629. etc.

A company that manufacturers deep freezers has developed a new formula of refrigerant, the substance used to cause cooling in refrigerators and freezers. To determine if freezers using the new formula of refrigerant are more efficient than those using the company's original formula, they conducted an experiment with two identical freezers. The first freezer was cooled using the new formula, and the second freezer was cooled using the original formula. A gallon of water was placed in each freezer, and they measured the time required for the water to turn to ice. Match the terms with the correct descriptions in the context of this scenario.
The answer to your question is :
Explanatory variable <--------> The first freezer
Response variable <---> The time required for the water to turn into ice in each freezer
control group <------------------> The second freezer
An Explanatory variable in an experiment is the variable that has been changed/manipulated by the researcher for the purpose of the experiment/research it is an independent variable ( as seen in first freezer )
A Response variable is the outcome of an experiment that serves as an evidence of the effect of the explanatory variable. it is a dependent variable
The control group is the made up of the refrigerators whom are not cooled using the new formula of refrigerant ( i.e. the second freezer )
hence the explanatory variable is the first freezer, the response variable is the time required for the water to turn into ice in each freezer, while the control group is the second freezer.
