deanna bought the poster shown below for her wall if a=11 cm,b=28cm,c=15cm,and d=17cm,what what is the area of the poster
Answer:
409[tex]cm^{2}[/tex]
Step-by-step explanation:
The area of the box wuld be c times d which is 15 times 17 which is 255.
the area of the triangle is [tex]\frac{1}{2}\\[/tex] (base x height) = [tex]\frac{1}{2}\\[/tex](28 x 11) = 14 x 11 = 154
154 + 255 = 409. area of 2D shape's unit is squared, so 409 [tex]cm^{2}[/tex]

How do we use fractions that equal 1 to create equivalent fractions?
Do you think that we should always express fractions in the lowest terms? (9/12 = ¾)
Answer:
no
Step-by-step explanation:
The reason is if you have to add 3/4 + 7/12 you would have to convert it to have the same denominator for both fractions.

What are the measures of Angles a, b, and c? Show your work and explain your answers.
Answer:
a= 40, b= 50, c= 115
Step-by-step explanation:
a-
There is a theorem for a that gives you the answer:
Vertical angles are congruent
If the vertical angle of a is 40°, then a is also 40°.
That is what the theorem says.
b-
This one is kind of difficult, but let me break down the steps.
Now you already know that a is 40°, and the other angle besides b is a right angle because it shows a square, or 90°.
And now you need to know another law:
Every single triangle's angle adds up to 180°.
Now, this is basically a subtraction problem.
If two of the angles are there, and you know that all of the angles of a triangle add up to 180°, then you just need to know what 90 + 40 + x = 180 is
90 + 40 = 130
130 + x = 180
Subtract 130 from both sides
130 + x = 180
-130 -130
x=50, which means that all of the angles add up to 180°, or following the law.
c-
This one is different as well.
You can very clearly see that it is a straight line that crosses 65° and c.
There is one more law as well:
A straight line is 180°.
If that line that 65 degrees and c sits on is straight, that means that-
65 + x = 180, or
180 - 65 = x
180-65 = 115, and c=115.
It also follows that law; 115 + 65 = 180, which means that it is correct.
Hope this helps :)

Hii :)
We know that there are 2 boys, so we should divide 2 by 43. But first..
We need to add the total amount the boys spent together, then subtract,then divide
13+5=18.
The boys spent a total amount of 18 cents.
Next, we need to subtract 18 by 43.
43-18=25.
So, if we were to spilt the 25 evenly, or divide by 2, the answer would be 12.5 cents. But, we need to find what they had to start with.
43 divided by 2 is 21.5. So each boy had 21.5 cents to start with.

To measure the center, median is the best method.
What is median?The value that divides the mathematical numbers or expressions in half is known as the median. The middle data point is known as the median value.
To find the median:
First, organize the data points in ascending order before calculating the median.
The middle number on the list is the median if the number of observations is odd.
Take the value of the (n+1)/2-th term, where n is the total number of observations, to determine this.
Otherwise, the median is the simple average of the middle two figures if the number of observations is even.
Therefore, the median is the best method to find the measure of the center.

.Edward deposited $9,500 into a savings account 3 years ago. The simple interest rate is 4%. How much money did Edward earn in interest?
Answer:
first, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.
Solving our equation:
A = 6000(1 + (0.03 × 4)) = 6720
A = $6,720.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 3% per year for 4 years is $6,720.00.
Hope it helps!!!!!!!!brainliest pls!!!!!!!Answer:
$380
Step-by-step explanation:
If he got 4% interest over the three years then he gained $380 because 9,500 divided by 100 is 95 multiplied by 4 is 380 and thats how much he gained. Total he would now have $9,880.

Answer:
y = x + 5
Step-by-step explanation:
Slope (m) formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-4}{3-(-1)}\\\\m=\frac{8-4}{3+1}\\\\m=\frac{4}{4}\\\\m=1[/tex]
y = mx + b
y = 1x + b OR y = x + b
(-1, 4)
y = x + b
4 = -1 + b
+1 +1
5 = b
y = x + 5
Check your answer using y = x + 5 and (3, 8):
y = x + 5
8 = 3 + 5
8 = 8
This statement is true
Therefore, our final answer is, y = x + 5.

A coffee shop surveyed three groups of 5 customers to find out how many cups of coffee the customers drink in one day. This table shows the results of the three samples.
Survey Cups of Coffee
Group 1 {1, 3, 2, 2, 4}
Group 2 {4, 1, 3, 2, 1}
Group 3 {5, 4, 6, 4, 6}
Identify any surveys that are likely biased. Based on the unbiased surveys, estimate the mean number of cups of coffee the customers drink in one day.
Enter your answer in the box. Round to the nearest whole number.
cups
Answer:
The mean number of cups of coffer per person was 3.2 cups.
There is nothing in the problem that leads me to believe that the surveys were biased (Was there more to this problem?).
Therefore, we will use all of the values to find the mean. Add up all the values and we have a total sum of 48. Now, divide by 15 to get a mean on 3.2.
