Mrs. Clements has a table with a top that is shaped like the trapezoid shown. Which expression can Mrs. Clements use to find the area of the table top, in square feet? A (5x3x4) + (4x2) C (4 3 5) 1 1··2(2 3 4) B (9 3 4) 1 (4 3 5) D (4 3 9) 1 1··2(5 3 4) 5 feet 4 feet 2 feet 9 feet
Answer:
60
Step-by-step explanation:
The expression Mrs. Clements use to find the area of the tabletop, in square feet is 0.5 * (5 + 9) * 4
How to determine the area of the tabletop?The dimension of the tabletop is:
Parallel sides = 5 feet and 9 feet
Height = 4 feet
The area is then calculated using:
Area = 0.5 * (Sum of parallel sides) * Height
This gives
Area = 0.5 * (5 + 9) * 4
Hence, the expression Mrs. Clements use to find the area of the tabletop, in square feet is 0.5 * (5 + 9) * 4

Answer:
2√2 = x
Step-by-step explanation:
x
---- = sin 45 degrees, or
4
x 1
----- = -----
4 √2
this results in x = 4 / √2 = 4√2/2 = 2√2 = x
The value of the variable 'x' will be 2√2 units. Then the correct option is C.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The two triangular legs and their opposing angles are congruent in an isosceles triangle.
The triangle is an isosceles right-angle triangle. Then by the Pythagoras theorem, we have
4² = x² + x²
2x² = 16
x² = 8
x = 2√2
The value of the variable 'x' will be 2√2 units. Then the correct option is C.

The value of S4 for infinity sigma n=1 10(0.2)^n-1 is B. 12.48
Step-by-step explanation:
Summationsummation is the addition of a sequence of any kind of numbers
Here we need to find the summation of first four terms.
so ,
S₄ = 10 ×[tex]( 0. 2 )^{4-1}[/tex] = 0.08
S₃ = 10 × [tex]( 0.2 )^{3-1}[/tex] = 0.4
S₂ = 10 × [tex]( 0.2 )^{2-1}[/tex] = 2
S₁ = 10 × [tex]( 0.2 )^{1-1}[/tex] = 10
Thus, The Value of Summation = S₄ + S₃ + S₂ + S₁ = 12.48

3. Find the surface area of the square pyramid.
Answer:
answer: 105
Step-by-step explanation:
For triangle area you just have to do base × height ÷ 2 So we will do 8 × 5 = 40 then divide by 40 by 2 so 40 ÷ 2 = 20 now we have 1 triangles area we can find the rest because each of these triangles are equal so 20 × 4 = 80 now we just have to do the square so thats easily just base × height so 5 × 5 = 25 now we just add 80 and 25 so 80 + 25 = 105 so 105 is our surface area!

Market price of an article is 30% above its purchase price.If the shopkeeper sold it by allowing 15% discount,then (i) Calculate the market price and profit amount if the shopkeeper paid 2500 for the article.
solution by step:
The market price and profit amount if the shopkeeper paid 2500 for the article will be 3250 and 11.05%.
What exactly is profit?Profit is made when the money generated from a commercial operation exceeds the expenses, charges, and taxes associated with operating the activity in question.
Given data;
Purchase price = 2500
Given condition;
The markup is 30% more than the purchasing price.
Mark Price is found as;
[tex]\rm MP = \frac{130}{100}\times 2500 \\\\ MP =130\times 25\\\\ MP=3250[/tex]
The marked price of an article will be 3250.
Since we are aware that discounts usually apply to mark prices, a 15 percent discount is now being offered;
[tex]\rm \frac{85}{100}\times 3250 = 2762.5 RS[/tex]
The profit in the article is found as;
Profit = 2762.5-2500
Profit = 226.25 RS
Now profit % is found as;
[tex]\% profit = \frac{276.25}{2500}\times 100 \\\\ \% profit = 11.05 \%[/tex];
Hence, the market price and profit amount, if the shopkeeper paid 2500 for the article, will be 3250 and 11.05%.

Each of 6 students reported the number of movies they saw in the past year. Here is what they reported.
8,6,8,5,4,6
Find the mean number of movies that the students saw.
If necessary, round your answer to the nearest tenth.
Answer:
[tex]\boxed {\boxed {\sf mean \approx 6.3}}[/tex]
Step-by-step explanation:
We are given this data and asked to find the data.
8, 7, 8, 5, 4, 6
The mean is also called the average. It is found by dividing the sum of the terms by the number of terms.
[tex]mean= \frac {sum \ of \ terms}{number \ of \ terms}[/tex]
First, we calculate the sum of the terms. Add up all the numbers.
sum= 8+7+8+5+4+6 sum= 38[tex]mean=\frac{38}{number \ of \ terms}[/tex]
Next, divide by the number of terms. There are 6 terms (also, there are 6 students that reported).
[tex]mean=\frac{38}{6}\\mean=6.33333333333[/tex]
Let's round to the nearest tenth.
6.33333333333The 3 in the hundredth place tells us to leave the 3 in the tenth place.
[tex]mean \approx 6.3[/tex]
The mean number of movies the students saw is approximately 6.3
Step-by-step explanation:
Terms are
8,6,8,5,4,6[tex] \rm \mapsto \: mean = \frac{sum \: of \: terms}{number \: of \: terms} \\ \rm \mapsto \: \frac{8 + 6 + 8 + 5 + 4 + 6}{6} \\ \rm \mapsto \: \frac{14 + 13 + 10}{6} \\ \rm \mapsto \: \frac{37}{6} \\ \rm \mapsto \: 6.166 \\ \rm \mapsto \: 6.1 \overline{6} \\ \rm \mapsto \: 6.2[/tex]

If function f is the parent exponential function , what is the equation of transformed function g in terms of function f?
Replace the value of a to complete the equation.
Answer:
This problem is acually really simple.
Step-by-step explanation:
all you have to do is replace the a with a 3. SO It would look like this:
g(x)=3f(x)
hope this helps :)
The equation of the function g(x) is g(x) = 3f(x) or g(x) = 3e^x
How to determine the equation of g(x)?The function f(x) is given as:
f(x)= e^x
The function is stretched by a factor of 3 to get the function g(x)
This means that:
g(x) = 3 * f(x)
Evaluate the product
g(x) = 3f(x)
Hence, the equation of the function g(x) is g(x) = 3f(x) or g(x) = 3e^x
