Answer:
10 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (5, 2) and (x₂, y₂ ) = (- 3, - 4)
d = [tex]\sqrt{(-3-5)^2+(-4-2)^2}[/tex]
= [tex]\sqrt{(-8)^2+(-6)^2}[/tex]
= [tex]\sqrt{64+36}[/tex]
= [tex]\sqrt{100}[/tex]

True or False: The area of a circle with diameter d = 2r = 10 is greater than the area of an ellipse with major axis 2a = 10. Explain your answer. Note: the area of an ellipse is calculated with the formula = (with ‘a’ the length of the semi-major axis and ‘b’ the length of the semiminor axis). Explain why as well.
Answer:
True
Step-by-step explanation:
So the radius would be 5 (as you times it by 2 to get 10)
Therefore
2a=10 is the same as what the circle with diameter d=2r=10

Answer: D. 2
Step-by-step explanation:
Given
y-1=2(x--2)
Change signs
y-1=2(x+2)
Expand parenthesis
y-1=2x+4
Add 1 on both sides to isolate "y"
y-1+1=2x+4+1
y=2x+4
So the slope is 2

From the isosceles triangle:
h = 4sin30
h = 4(1/2)
h = 2 miles
From Pythagoras theorem:
x² = 4² - h² = 4² - 2²
x = √12
x = 3.46 miles
Total distance = 2×3.46 = 6.9 miles
Thus, they are both 6.9 miles apart after one hour if they both hike 4 miles/hour option (B) 6.9 miles is correct.

An angle measure 8 less than the measure of its supplementary angle what is the measure of each angle
Answer:
94° and 86°
Step-by-step explanation:
'x-8' = smaller angle
'x' = larger angle
x - 8 + x = 180
2x = 188
x = 94

A shopper at a clearance store is pleased to discover some microscopes on sale for $24 dollars each. The original price tags read $40. What percent is the discount?
If 15% of a number is 30 and 40% of the same number is 80, find 25% of that number.
Answer:
50
Step-by-step explanation:
let the number be x
15% of x= 0.15x
0.15x=30
(divide both sides by 0.15)
x= 200
25% of 200 = 25/100 *200
= 50

Tamara earned an a on 5/8 of her spelling test of those spelling says she earned a perfect score on 1/5 of them find what fraction of cameras total spelling test did she on a perfect score show your work
Answer:
she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests
Step-by-step explanation:
Tamara earned an A in 5/8 of all the tests she took.
In 1/5 of the those tests she got an A, she had a perfect score.
1/5 of 5/8 is 1/5 * 5/8 which equals 5/40 which can be reduced to 1/8.
That means that in 1/8 of all tests she took she got a perfect score.
She took a total of 32 spelling tests.
1/8 of 32 = 1/8 * 32 = 32/8 = 4
Answer:
she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests

If the angle of a sector measures 45° what fraction of the circle is the sector
The fraction of the circle measured by a sector which subtends an angle; 45° is; 1/8 (one-eighth).
It has been established from circle geometry that the angle subtended at a point is 360°.
On this note, the algebraic sum of angles in a circle is; 360°.In essence, a sector which measures 45° is only 1/8 of the circle.
45/360 = 1/8.Read more on sectors and circles;

The work of a student to solve a set of equations is shown below:
Equation 1: x + 2y = 10
Equation 2: 2x + 5y = 15
Step 1: −2(x + 2y) = −2(10)
2x + 5y = 15
Step 2: −2x − 4y = −10
2x + 5y = 15
Step 3: 1y = 5
Step 4: x + 2(1) = 10
Step 5: x = 8
In which step did the student first make an error?
Step 1
Step 2
Step 3
Step 4
Answer:
Step 2 has error and step 4 has error.
Step-by-step explanation:
Here we can see that elimination method is applied to solve the system of equations for which -2 is multiplied both sides of equation first
-2(x+2y)=-2(10 which is correct
but in step 2
left side is -2x-4y and the right side is -10 which has to be -20 which makes this step wrong and this is the error made by student.
in Step 4 also ,value of the y has to be 5 but student plugged y =1 which is also error by student.
Correct solution is
-2x-4y= -20
2x+ 5y= 15
on adding ,we get
y = -5
plugging y =5 in equation x+2y= 10 ,we get x+2(-5) =10 ,we get x = 20
therefore (20,-5) is the solution

Have a nice day <3
After changing the unit of 144 inches into yards the number equivalent to 144 inches is 4 yards. Hence option (a) is true.
Given that,
Change the number 144 inches into yards.
Used the concept of measurement unit which stated that,
A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.
Since we know that,
1 yards = 36 inches
1 inch = 1/36 yards
So, we can change the number 144 inches into yards,
1 inch = 1/36 yards
144 inches = 144/36 yards
= 4 yards
Therefore, 144 inches is equivalent to 4 inches.
Option (a) is true.
