Answer:
Not on there but it is 76in2
Step-by-step explanation:
Starting with the trapezoid. We know that a trapezoid can be split into 2 triangles and 1 rectangle. So the area of the trapezoid will be 4+32+4 which is 40 now that we know the trapezoid's area we can find the rectangle's area. The rectangle's area will be 12x3 which is 36. So, you would add both:40+36= 76in2.

Answer:
In which step did Sierra make a mistake? Step 2.
What should she have done instead? add the x and the 5x
Step-by-step explanation:
she had the expression:
[tex]x + 8 + 5(x - 4)[/tex]
and then she multiplied the 5 by the parentheses (step 1):
[tex]x + 8 + 5x - 20[/tex]
no mistakes so far
then she has: [tex]5x + 8 - 20[/tex] (step 2) Here is the mistake, she forgot about the 'x' that she has at the beginning of the expression.
What you should have done is add the x and the 5x, so she must a 6x in the following step (correcting the mistake):

Step-by-step explanation:
-1-4=-5
mark my brainliest? :)
Final answer:
The temperature needs to change by 4°F to reach the preferred reading at -5°F.
Explanation:
The current temperature of the restaurant's freezer is -1°F. To achieve the preferred temperature of -5°F, we need to calculate the difference between the two temperatures The temperature needs to change to reach the preferred reading is 5°. Thus,
Calculating the difference between the preferred temperature (-5°F) and the current reading (-1°F): -5 - (-1) = -5 + 1 = -4°F.Since temperatures are measured in terms of how much they deviate from zero, it needs to decrease, so the change will be positive: 4°F.Therefore, the temperature needs to decrease by 4°F to reach the preferred reading.

¿Cuál dígito debe ir en el recuadro para
que el siguiente número sea divisible
entre 2, 3 y 9? 8,? 48
Answer:
7
Step-by-step explanation:
English:
Which digit should go in the box to
make the next number divisible
between 2, 3 and 9? 8 ,? 48
Let x be the number, then the number will look like this:
8x48
This number is already divisible by 2, because it ends with an even number.
Now we need to check for divsibility by 3.
For this to be divisible by 3, the sum of the digit should be a multiple of 3.
[tex]8 + x + 4 + 8 = x +20[/tex]
We know if a number is divsible by 9, it is also divsible by 3.
So
[tex]x + 20=9,18,27,....[/tex]
The least positive solution is
[tex]x + 20 = 27[/tex]
[tex]x = 27 - 20[/tex]
[tex]x = 7[/tex]
Therefore 8748 is divsible by 2,3, and 9.

How many solutions does this system have? 2x+8y=16,-3x+6y=30
Final answer:
To determine the number of solutions for the system of equations 2x+8y=16 and -3x+6y=30, the elimination method can be used. After multiplying and combining the equations, it is found that the system has a unique solution at (-4, 3). This means the two lines intersect at exactly one point.
Explanation:
The student is asking about the number of solutions for the system of equations 2x+8y=16 and -3x+6y=30. To find out how many solutions the system has, we can use either substitution, elimination, or graphing methods. Substitution involves solving one equation for one variable and then substituting that into the other equation. Elimination involves adding or subtracting equations to cancel out one of the variables, which can be followed by solving for the remaining variable. Graphing would involve plotting both equations and observing their intersection points.
For this specific problem:
Equation 1: 2x+8y=16
Equation 2: -3x+6y=30
If we try to use the elimination method, multiplying Equation 1 by 3 and Equation 2 by 2 would allow us to cancel out the x's:
Multiplying Equation 1 by 3: 6x+24y=48
Multiplying Equation 2 by 2: -6x+12y=60
Adding these equations together gives us:
36y=108, which simplifies to y=3. Substituting y=3 into Equation 1, we can solve for x:
2x+8(3)=16
2x+24=16
2x=-8
x=-4
Thus, the system has a unique solution (x, y)=(-4, 3), indicating that the two lines intersect at exactly one point.
What is the exact distance from (−4, −2) to (4, 6)? (4 points)
A 24
B88
C 100
D 128
I would say it’s B! I know it isn’t A because we can say no to A since it’s such a small number and (-4,-2) to (4,6) isn’t 24 nor bigger then 100 so the only possible answer is B
I hope this helps and makes sense!
What’s the value of x in degrees
Answer:
92⁰
Step-by-step explanation:
a = 35⁰ ( vertically opposite )
b = 53⁰ (vertically opposite )
a + b + x = 180⁰ (Angle sum property of triangle)
35⁰ + 53⁰ + x = 180⁰
x = 180⁰ - 88⁰
x = 92⁰
Answer:
[tex]x = 97 \: \: degrees[/tex]
Step-by-step explanation:
[tex]a = 35 \\ b = 53 \\ (vertically \: \: opposite \: \: angles)[/tex]
[tex]35 + 53 + x = 180 \\ 86 + x = 180 \\ x = 180 - 83 \\ x =9 7 \: \: degrees[/tex]

What is bigger 2/8 or 4/16
Answer:
los dos son lo mismo solo que se multiplican por dos espero me entiendas
Step-by-step explanation:
Answer: They equal the same thing
Step-by-step explanation: Notice that the fractions that we're comparing in this problem have different denominators. When fractions have different denominators they're called unlike fractions.
To compare unlike fractions, we must first get a common denominator.
The common denominator of 8 and 16 will be the least common multiple of 8 and 16 or 16. To get a 16 in the denominator of 2/8, we multiply the numerator and the denominator by 2 which gives us 4/16.
Now notice that 4/16 is equal to 4/16 since we changed 2/8.
Since 4/8 equals 4/8, these fractions are the same

Sandra wants to give a party for 60 people. She has a punch recipe that makes 2 gallons of punch and serves 15 people. How many gallons of punch should she make for her party? *
Answer:8
Step-by-step explanation:
Sandra wants to give a party for 60 people. Given that her punch recipe, which yields 2 gallons, serves 15 people, she can use a proportional relationship to determine she will need 8 gallons of punch.
Explanation:This question can be solved by setting up a proportional relationship. In the given case, we know that the punch recipe produces 2 gallons of punch and serves 15 people. Hence, the ratio is 2 gallons per 15 people or 2/15.
Now, let's use this ratio to calculate how many gallons of punch she will need for 60 people. Form a proportion as follows:
2/15 = x/60
Where 'x' represents the number of gallons needed for 60 people. To find 'x', cross-multiply:
2 * 60 = 15 * x
120 = 15x
Then, divide both sides by 15 to solve for 'x':
x = 120/15
So, 'x' equals 8. That means Sandra needs to make 8 gallons of punch for her party.

Pat's average weekly income from her part time job was 15% more in September than it was in July. her average weekly income in July was 10% less than it was in August. if her average weekly income in September was $207, what was her average weekly income in August?
Her average weekly income in August was $200.
Step-by-step explanation:
To find the income in july :
Given that,
Her average weekly income in September was $207.Her part time job was 15% more in September than it was in July.Let,
'x' be the 100% of income she got in July.
Therefore, the income $207 in September is 115% of x.
⇒ 115% of x = 207
⇒ 1.15 × x = 207
⇒ x = 207 / 1.15
⇒ x = 180
∴ Her average weekly income in July was $180.
To find the income in August :
Given that,
Her average weekly income in July was 10% less than it was in August.We found that, $180 is the average weekly income in July which is 10% less than August.Let,
'y' be the 100% of income she got in August.
Therefore, the income $180 in July is 90% of y.
⇒ 90% of y = 180
⇒ 0.9 × y = 180
⇒ y = 180/0.9
⇒ y = 200
∴ Her average weekly income in August was $200.
her average weekly income in August was $200 .
Step-by-step explanation:
Let in July income was x , So in September :
⇒ [tex]x+\frac{15x}{100}[/tex]
According to question , her average weekly income in September was $207 i.e.
⇒ [tex]x+\frac{15x}{100}=207[/tex]
⇒ [tex]\frac{115x}{100}=207[/tex]
⇒ [tex]x=207(\frac{100}{115})[/tex]
⇒ [tex]x=180[/tex]
Now , average weekly income in July was 10% less than it was in August , let income of august = y, i.e.
Income in august = [tex]180+\frac{August(10)}{100}[/tex]
⇒ [tex]y=180 + \frac{y(10)}{100}[/tex]
⇒ [tex]\frac{9}{10}y=180[/tex]
⇒ [tex]y=\$200[/tex]
Therefore , her average weekly income in August was $200 .
