what is the distance between (-6,8) and (-3,9)
A) 4
B) 6
C) square root of 10
D) square root of 15
Answer:
I would say it is close to 4, but not 4.
Step-by-step explanation:
So I rounded the distance between the 2 plots with a line, and I got either 3.8 or 3.1
square root of 10 = 3.1
square root of 15 = 3.8
The picture is my graph I used to base it, so I would generally consider how close it is to 4 saying C. Square root of 10.
(I only chose 3.1 because I went up on the graph 3 squares with my line. It did not quite reach. I went 1/10(0.1) of a whole up further, and it resulted in the square root of 10 choice.)
For a project in his Geometry class, Nathaniel uses a mirror on the ground to measure the height of his school’s flagpole. He walks a distance of 7.95 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. He then steps 1.15 meters to the other side of the mirror, until he can see the top of the flagpole clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.65 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.
The height of the flagpole to the nearest hundredth is 11.41 m
Similar shapesIn order to get the height of the flagpole, we will use the similarity theorem of shapes.
From the given diagram, we will have the expression
1.65/1.15 = x/7.95
Cross multiply
1.15x = 1.65 * 7.95
1.15x = 13.1175
x = 13.1175/1.15
x = 11.406
Hence the height of the flagpole to the nearest hundredth is 11.41 m

If two geometrical figures are congruent, then their corresponding sides are congruent.
Add. Simplify your answer.
Step-by-step explanation:
Add the ones with like terms.
which means the ones with things in common.
4/5x^2 + 1/4x^2 i'm adding this first because we have x^2 on both sides.
(4/5 + 1/4)x^2
= (5+16/20)x^2
= (21/20)x^2
the next terms are those with x as common.
(1/4 +- 1/5)x...take the sign into consideration while dealing with the terms within the equations.
=(1/4 - 1/5)x
=(5 - 4/ 20)x
= (1/20)x
= (1 × x) / 20
= x/20.
last ones are the constant terms(numbers)
1/6 + 2/3

Answer:
240 cm²
Step-by-step explanation:
Split the shape into a trapezoid (top half) and a rectangle (bottom half).
Area of a rectangle = width x length
⇒ area = 6.5 x 20 = 130 cm²
[tex]\textsf{Area of a trapezoid} = \frac{1}{2}(a+b)h[/tex]
(where a and b are the lengths of the base and top, and h is the height)
⇒ [tex]\textsf{area} = \frac{1}{2}(20+20)\times5.5[/tex]
⇒ area = 110 cm²
Total area = area of rectangle + area of trapezoid
⇒ area = 130 + 110 = 240 cm²

The Pie Chart is the best type of chart that could be used to represent the distribution of this data.
What is a Pie Chart?A pie chart is a type of circular statistical graph used for the representation of a data set. The graph's segments are proportionate to the percentage of the total in each group.
However, the proportion of each portion of the pie chart is proportional to the number of the group as a whole.
The full pie chart represents 100% of the whole, whereas The pie portion represents sections of the total.Therefore, from the given information contains many data sets, each data can be represented in each portion to make a full Pie Chart.

13. x = 11
15. x = 5
Step-by-step explanation:
In each part, I set up a proportion and cross multiplied to solve.
5. 4/3 = 2x + 4/x + 7
x = 8
11. 25/30 = 48/x
x = 57.6

i write a test in 2 days and i dont know how to find percentages can anyone help me
percentage is a ratio of a number or fraction to 100
percentage =per(every) + cent (100)
per cent = per 100
percentage calculation formula (%) = (part / whole ) ×100
percentage increase equation = 100 ×( final - initial) /initial
ex1 : 2% is 2 percent = 2/100 =2:100
ex2: 35% = 35/100
48% = 48/100
ex3 : find the following 10% of 25,000
step 1 : convert 10% into fraction = 10/100
step 2 : multiply the fraction with value = 10/100× 25,000
answer = 2,500
ex4 : what is 7% of 68m ?
step 1 : convert 7% into fraction = 7/100
step 2 : multiply the fraction with value = 7/100 × 68
answer = 4.76 m
ex5 : The original price of a shirt was $10. It was decreased to $5 . What is the percent decrease of the price of this shirt?
step 1 : find the amount decreased = $10–$5 =$5
step 2 : write as part / whole = $5 / $10 = $0.5
step 3 : multiply by 100 = 0.5 × 100 = 50%
ex6 : Mary has a monthly salary of $21,000. She spends $350 per month on food. What percent of her monthly salary does she spend on food?
step 1 : write as part /whole and multiply by 100
= ( 350 / 21000 ) ×100 = 1.7 %
ex6 : The price of a pair of shoes was decreased by 21% to $100. What was the original price of the trousers?
step 1 : write % as fraction = 21/100
original price = y
(y × 21/100 ) = amount decreased --------- 1
y - amount decreased = $100 -------------- 2
rearrange equation 2 as;
y - $100 = amount decreased -------------- 3
when you equate both equation 1 and 3 you should get the ans y = $ 126.58
ex6 : The price of an item changed from $120 to $100. Then later the price decreased again from $100 to $80. Which of the two decreases was larger in percentage term?
step 1 : part / whole = (120 - 100) / 120 = 0.17 = 17%
step 2 : part / whole = (100 - 80) / 100 = 0.20 = 20%
The part were the same in both cases but the whole was smaller in the second decrease.
ex7 : A family had dinner in a restaurant and paid $35 for food. They also had to pay 9.5% sale tax and 10% for the tip. How much did they pay for the dinner?
for food = $35
sale tax = 9.5/100 × 35 = $3.33
tip = 10 /100 × 35 = 3.5
total = $45.83
ex8 : Smith invested $5000 for two years. For the first year, the rate of interest was 7% and the second year it was 8.5%. How much interest did he earn at the end of the two year period?
Answer
Interest at the end of the first year
7/100 * 5000 = $350
Interest at the end of the second year
8.5/100 * (5000 + 350) = $454.75
Total interest at the end of the two year period is
$350 + $454.75 = $804.75

Given equation,
→ 3(2x - 7) = 5 - (1 - x)
Now the value of x will be,
→ 3(2x - 7) = 5 - (1 - x)
→ 6x - 21 = 5 - 1 + x

Raj purchased an article for Rs400 and sold it for Rs 420. Find the lrofit or loss percent
Given :-
Raj purchased an article for Rs420 .He sold it for Rs 420 .To Find :-
The profit or loss percentage .Solution :-
Here the cost price for Raj is Rs 400 and Selling price is Rs420 .
Here since SP > CP , so there's a profit .
→ Profit = SP - CP
→ Profit = Rs420 - Rs400
→ Profit = Rs 20
Now we can calculate the profit% as ,
→ Profit/CP * 100
→ Rs 20/ Rs 400 * 100 %
→ 20/4%
→ 5%
Hence the profit is 5% .
I hope this helps .
Answer:
5%Step-by-step explanation:
Cost price of the article = Rs 400
Selling price of the article = Rs 420
As, S.P > C.P
Profit = S.P – C.P
= Rs( 420 – 400)
⠀⠀⠀= Rs 20
So,
Profit percent = (20/400 × 100)%
⠀⠀⠀⠀⠀⠀⠀⠀ = (20/4) %
⠀⠀⠀⠀⠀⠀⠀⠀ = 5 %

Find the x-intercept and y-intercept
from the following linear equation:
-2x + 4y = -16
=
x - intercept ([?], 1)
y - intercept (1,1)
[]
Answer:
[tex] x\ intercept = (-8,0)\\\\ y\ intercept = (0,-4)[/tex]
Step-by-step explanation:
A equation is given and we need to find out the x and y intercept . The given equation is ,
[tex]\longrightarrow -2x + 4y =-16[/tex]
In order to find out the y intercept , substitute x = 0 in the given equation,as;
[tex] -2x + 4y =-16\\\\\longrightarrow -2(0)+4y =-16\\\\\longrightarrow 4y = -16\\\\\longrightarrow y =\dfrac{-16}{4}\\\\\longrightarrow y = -4 [/tex]
Again to find x intercept substitute y = 0 in the given equation, as ;
[tex]\longrightarrow -2x + 4y = -16 \\\\\longrightarrow -2x +4(0)=16\\\\\longrightarrow -2x = 16\\\\\longrightarrow x =\dfrac{16}{-2}\\\\\longrightarrow x =-8[/tex]
