Answer:
85%
Step-by-step explanation:
First, let's add up the ratios and use it to divide 120. That way we can find out how many people each ratio is.
17 +3 = 20
120/20 = 6
Each individual ratio is equal to 6.
17 * 6 = 102
3 * 6 = 18
102/120 = percentage of who passed
= 0.85
85 percent of learners passed.
John measured two pieces of string. One piece measured 7/12 m and the other measured 4/7 m.
Select the true statement about the lengths of John's string.
1) 7/12= 0.58, 4/7= 0.57
they are about 1/2
2) 7/12 + 4/7 = 97/84= 1.15 approximately 1
which is 1m from the option

A Mathematics
B Academic literacy
C Qualitative literacy
D Quantitative literacy
The criteria that is excluded from national benchmark test is Qualitative literacy. That is option C.
National Benchmark Test is an academic assessment test usually written by students that are about entering the university.
The National Benchmark Tests comprise three multiple choice tests, written as:
A combined Academic Literacy: this tests the ability of the candidate to adapt fully to the academic demands of higher degree.and Quantitative Literacy (AQL) test: this tests the ability of the candidate to solve problems in a real context that is relevant to higher education study. A separate Mathematics test: this tests the ability of the candidate to related to mathematical concepts needed for a higher education.Qualitative literacy is the ability to understand and interpret qualitative evidence. It is not included in the national benchmark test criteria.

Answer:
[tex](\sqrt{6}+\sqrt{3})(\sqrt{6}-\sqrt{3})=3[/tex]
[tex](\sqrt{5}-\sqrt{2})(\sqrt{2}+\sqrt{5})=3[/tex]
Step-by-step explanation:
We want to simplify the expression:
[tex](\sqrt{6}+\sqrt{3})(\sqrt{6}-\sqrt{3})[/tex]
Notice that this is the difference of two squares pattern. Namely:
[tex]a^2-b^2=(a+b)(a-b)[/tex]
If we let a = √6 and b =√3, we acquire:
[tex](a+b)(a-b)[/tex]
Expand accordingly:
[tex]=a^2-b^2[/tex]
Back-substitute:
[tex]=(\sqrt{6})^2-(\sqrt{3})^2[/tex]
Simplify:
[tex]=6-3=3[/tex]
For the second expression, we have a similar pattern:
[tex](\sqrt{5}-\sqrt{2})(\sqrt{2}+\sqrt{5})[/tex]
We can first rewrite the expression (commutative property):
[tex]=(\sqrt{5}-\sqrt{2})(\sqrt{5}+\sqrt{2})[/tex]
And if we let a = √5 and b = √2:
[tex]=(a-b)(a+b)[/tex]
Expand accordingly:
[tex]=a^2-b^2[/tex]
Back-substitute and simplify:
[tex]=(\sqrt{5})^2-(\sqrt{2})^2=5-2=3[/tex]

Answer:
66 in^2
Step-by-step explanation:
Imagine that the figure is a whole square, where the space between is filled in.
Find the area of the imaginary square (l x w):
9 in. x 9 in. = 81 in^2
Lets make that whole square the original figure it used to be (take away the space we “filled in”)
Lets find the area of the space we filled in:
5 in x 3 in= 15 in^2
Subtract the imaginary square’s area by the area of the space that was originally blank:
81 in^2 - 15 in^2 = 66 in^2
66 in^2 IS YOUR FINAL ANSWER, that is the real area of the composite figure you have.

What is the answer and explain why
Answer:
20
Step-by-step explanation:
Take note of the important information/key words:
60 total ornaments
3 grandchildren
Divide them evenly
Set up an equation:
60 ornaments ÷ 3 grandchildren = ornaments per grandchild
60 ÷ 3 = 20 ornaments per grandchild.
In other words, each grandchild will receive 20 ornaments.
The screen at Dallas' AT&T Stadium is 175 feet wide. A movie theatre screen with
similar dimensions is 40 feet wide with a screen area of 896 Ft. What is the area of
the screen at AT&T Stadium? Round to the nearest square foot.
Answer:
17150 ft²
Step-by-step explanation:
Given the ratio of sides = a : b , then
ratio of areas = a² : b²
Here ratio of sides = 175 : 40 = 35 : 8 , then
ratio of areas = 35² : 8² = 1225 : 64
let x be the area of AT & T Stadium then by proportion
[tex]\frac{x}{1225}[/tex] = [tex]\frac{896}{64}[/tex] ( cross- multiply )
64x = 896 × 1225 = 1097600 ( divide both sides by 64 )
x = 17150
The AT & T screen has an area of 17150 ft²

Is the graph increasing, decreasing, or constant? I need help with it!!
Answer:Decreasing
Step-by-step explanation:
The line is going down.
The given graph is decreasing. The correct option is A.
Increasing graph: A graph is considered increasing if it moves upwards as you move from left to right along the x-axis. In other words, the y-values increase as the x-values increase. This is often represented by a positive slope, where the line or curve ascends as it extends to the right.
Decreasing graph: A graph is considered decreasing if it moves downwards as you move from left to right along the x-axis. In this case, the y-values decrease as the x-values increase. It is represented by a negative slope, where the line or curve descends as it extends to the right.
Constant graph: A graph is considered constant if it remains flat and does not rise or fall as you move along the x-axis. The y-values do not change with increasing x-values, and this is represented by a horizontal line.
In given figure the line goes to downwards and the vales of y is decreasing for the increasing values of x.
Hence, the given graph is decreasing. The correct option is A.

Write an in Standard Folm given the following points:
(-2, 6), (9,8)
Answer:
2/11 x + 70/11
Step-by-step explanation:
Given the coordinate (-2, 6), (9,8), the equation in standard form is of the form y = mx+b
m is the slope = 8-6/9-(-2)
m = 2/11
Get the y-intercept
Substitute m = 2/11 and (-2, 6) into the expression y = mx+b
6 = 2/11(-2)+b
6 = -4/11 + b
b = 6 + 4/11
b = (66+4)/11
b = 70/11
Get the required equation
y = 2/11 x + 70/11
Hence the required equation is 2/11 x + 70/11

d. 195.3 cm
c. 165.6 cm2
b. 312.5 cm?
a. 331.2 cm2
Answer:
c. 165.6 cm²
Step-by-step explanation:
We are given two sides of a triangle and an included angle. To find the area, we would apply the following formula:
Area = ½*b*c*Sin(A)
b = 25 cm
c = 25 cm
A = 32°
Area = ½*25*25*Sin(32)
Area = 165.59977
Area ≈ 165.6 cm² (nearest tenth)

A fruitseller bought 50kg of the fruits. He sold 30kg of fruits for the cost price of 35kg of fruits and he sold the remaining quantity for the cost Price of 18kg of fruits. calculate his profit or loss percent in the total transaction.
Answer:-let the cost price be 50x
→he sells 30kg of fruits on it's CP of 35 kg
→CP of 30kg fruits = 30x
→SP of 35kg fruits = 35x
→remaing fruits are 20kg
→he sells 20kg of fruits on CP of 16kg
→CP of 20kg fruits = 20x
→SP of 20kg fruits = 16x
→total CP is = 50x
→total SP is = (35 + 16) = 51x
→SP > CP (it means profit)
→profit = SP-CP
→ 51-50
→ 1
Now,→ Profit% = gain/CP × 100
→ Profit% = 1/50 × 100
→ 2%
Hence the fruit seller had a profit% of 2%.

On a piece of paper, graph f(x) = {6 if -5 < x < -1
{4 if -1 < x < 2
{2 if 2< x < 5 .
Then determine which
answer choice matches the graph you drew.
Explanation:
You are basically graphing the three horizontal lines y = 6, y = 4 and y = 2; however, there are restrictions to each line.
The first line (y = 6) is only graphed when [tex]-5 < x \le -1[/tex]The second line (y = 4) is only graphed when [tex]-1 < x \le 2[/tex]The third line (y = 2) is only graphed when [tex]2 < x \le 5[/tex]That's how we get the staircase pattern as shown in graph A. This is considered a piecewise function since we're graphing pieces of various other functions.
Note the use of open holes vs closed circles for the endpoints. The open holes correspond to parts of the inequality that don't have "or equal to", which means we leave that part out of the graph. In contrast, the closed fill in circles do have "or equal to" associated with them, so we do include those endpoints.

Here is some information about a holiday.
7 night holiday
$340 per person
8% discount if you book before 31 March
On 15 February, Naseem books this holiday for 2 people.
Calculate the total cost of his holiday.
Answer:
$625.6
Step-by-step explanation:
Information about a holiday:
7 night holiday
$340 per person
8% discount if you book before 31 March
Number of people Naseem booked the holiday for = 2
Date of booking of the holiday = February 15
Total cost of the holiday per person = cost per person - discount before March 31
= $340 - 8% of $340
= 340 - 8/100 * 340
= 340 - 0.08 * 340
= 340 - 27.2
= $312.8
Total cost of the holiday for 2 persons = 2 × Total cost of the holiday per person
= 2 * $312.8
= $625.6
