What is an equation of the line that passes through the points (3,6) and (−3,4)?
Answer:
y = x/3 +5
Step-by-step explanation:
Step1 : finding the slope
m = [tex]\frac{y2-y1}{x2-x1}[/tex]
(3,6) and (−3,4)
m = [tex]\frac{4-6}{-3-3}[/tex]
m = 1/3
Solving for the equation
y-y1 = m(x-x1) , (3,6)
y-6 = 1/3(x-3)
y = x/3 -1 +6
y = x/3 +5

Find x. Round to the nearest tenth.
Answer:
31.9°
Step-by-step explanation:
Applying the Law of Sines,
A = 75°a = 22 cmB = x°b = 12 cm⇒ sin75° / 22 = sin x° / 12
⇒ sin (45 + 30)° / 22 = sin x° / 12
⇒ (1/√2)(√3/2) + (1/√2)(1/2) / 22 = sin x° / 12
⇒ (1/√2)(√3 + 1 / 2) / 22 = sin x° / 12
⇒ 12 × (2.73/2.82) / 22 = sin x°
⇒ x = sin⁻¹ (0.529)
⇒ x = 31.9° (nearest tenth)
One angle on a parallelogram measures 155 what are the measures of the other angle
Answer: 25, 90 ,90
Step-by-step explanation:
One angle on a paralel = 155
=> x+ y + z + 155 = 360
x + y + z = 205 ; x + y ; y + z ; x + z = 180
x + y = 180
=> Z = 205 - 180
Z = 25 Degree
x = y = 90 degree

Melinda leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches Mary’s house. What is the shortest distance between Melinda’s house and Mary’s house?
The shortest distance between Melinda’s house and Mary’s house will be equal to 10 blocks.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal the square of the sum of the other two sides.
Here we have the condition that Melinda leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches Mary’s house.
Now we need to calculate shortest distance between Melinda’s house and Mary’s house.
The traingle is made from the given question and the shortest distance between Melinda's and Mary’s house will be the hypotenuse of the triangle.
So from the Pythagorean theorem:-
D²=6²+4²
D²=36+16
D²=100
D=10
Hence the shortest distance between Melinda’s house and Mary’s house will be equal to 10 blocks.

A lender estimates that the closing costs on a $170,000 home loan will be $6,375.00. The actual closing costs were 4.0%of the loan amount. Determine if the closing costs were higher or
lower than the estimate and by what percent
higher by 0.25%
higher by 0.5%
lower by 0.25%
lower by 0.5%
Answer:
(a) higher by 0.25%
Step-by-step explanation:
The error in the estimate is found by comparing the estimated rate to the actual rate.
__
The rate of estimated closing costs is ...
(estimated cost)/(home cost) × 100% = 6375/170000×100% = 3.75%
The actual rate is 4.00%.
actual - estimate = 4.00% -3.75% = 0.25%
The actual closing costs were higher than the estimate by 0.25%.

Answer:
Step-by-step explanation:
Mean: Add all the values and divide by the # of values
Median: The center of the values
Mode: The value that appears the most in the data set
Mean for data set 1: 86
Mean for data set 2: (85+89+71+85+86+91+92+96+87)/2= approximately 86.89
Median for data set 1: 72,75,78,80,88,90,95,98,98
We've sorted it from least to greatest, and the center is 88 because there is 4 values to the left of it, and 4 values to the right. It's at the very center.
Median for data set 2: 71,85,85,86,87,89,91,92,96
The center for this is 87 because it is again, at the absolute center/middle between the data.
Mode for data set 1: 98 because it appears 2 times, which is more often than other values
Mode for data set 2: 85 because it appears most often (2 times) in the data set

Jahnay wants to estimate how many ducks there are in her local park.
One day she puts a non-harmful tag on 20 of the ducks in the park.
The next day she catches 27 ducks and notices that 3 of these have a tag on them.
Work out an estimate for the total number of ducks in her local park.
Answer:
44 aproximately
Step-by-step explanation:
She puts a tag on 20 of them, the next day she catches 27 and notices 3 of them have a tag so we substract 27-3=24 we add 24 to the initial number of ducks (20) and the result is 44
Step-by-step explanation:
27÷3×20=180
or
3/27=20/n =180
so the numbers of ducks in her local park is 180

Find the volume of the right prism with a rhombus base.
Answer:
i think the answer is 150m³
Answer:
150 m³
Step-by-step explanation:
Formula
Area of a rhombus = (a · b) ÷ 2
(where a and b are the diagonals)
Given:
a = 10 mb = 3 m⇒ Area of the rhombus = (10 · 3) ÷ 2
= 30 ÷ 2
= 15 m²
Formula
Volume of a right prism = area of the base × length
Given:
area of the base = 15 m²length = 10 m⇒ Volume of the right prism = 15 × 10
= 150 m³
Solve for the value of t
Answer:

8t-96=0
We move all terms containing t to the left, all other terms to the right
8t=96

A Honda fit drove 3,172 km
Find what the gas mileage was for the vehicle used on the trip. Give the details on how you found it by showing the numbers and calculations you performed. Hint: a Honda fit drives 13.5 km per liter.
Answer:
See below ~
Step-by-step explanation:
Let's take an example :
I'm driving a car Z for 1,750 km and it has consumed 70 L of fuel.
===============================================================
Formula for mileage :
Mileage = Distance / Fuel consumed
=============================================================
Solving :
⇒ Mileage = 1,750 km / 70 L
⇒ Mileage = 25 km/L
=============================================================
Understanding by this method :
We can solve for the mileage of a car if we know how much distance it has covered in unit time, and the amount of fuel it has consumed, we can calculate mileage.
In a school of 900 pupils, 30% are boys and 40% of the boys wear glasses.
How many boys wear glasses?
Answer:
180
Step-by-step explanation:
First, we have to find out how many boys are in the school:
900 * 0.30 = 270
Now, we know that there are 270 boys. Out of these boys we need to find out how many boys have glasses:
270 * 0.40 = 108
180 is our answer.
What is 1 percent of 510
Answer: " 5.1 " .
____________
Step-by-step explanation:
____________
To find 1 percent (i.e. " 1% " ) of: 510 ;
Note: 1 % = (1 /100) = (1 ÷ 100) ;
Note the following about "dividing by "100" ;
We take the number: "510" in our case;
and move the decimal point "2 (two) places backward" .
We move it "backward" (instead of "forward") because we are "dividing" ;
and we are moving the decimal point "2 (two)" spaces backward; since we are dividing by "100" ; which has "2 (two) zeros" .
So: " (510.) ÷ 100 " ;
Take: " 510." ; and move the decimal point two (2) spaces backward:
5.10.
↩
To get: " 5.10 " ; which we can simplify as:
→ " 5.1 " ; which is our answer.
Hope this is helpful to you! Wishing you well!

Navya has 104 feet of craft wire that she uses to make earrings. If each pair of earring requires & foot of wire, how hiany pairs of earrings is Navya able to make?
Answer:
14 pairs of earrings
Step-by-step explanation:
Question
Navya has 10 ¹/₂ feet of craft wire that she uses to make earrings. If each pair of earring requires 3/4 foot of wire, how many pairs of earrings is Navya able to make.
Given:
Total wire = 10 ¹/₂ ftWire required to make 1 pair of earrings = 3/4 ftTo calculate the number of pairs of earrings Navya can make, divide the total amount of wire by the wire required to make 1 pair of earrings:
[tex]\begin{aligned}\implies \sf 10\frac{1}{2} \div \dfrac{3}{4} &= \sf \dfrac{21}{2} \div \dfrac{3}{4}\\ \\& = \sf \dfrac{21}{2} \times \dfrac{4}{3}\\ \\& = \sf \dfrac{21 \times 4}{2 \times 3}\\ \\& = \sf \dfrac{84}{6}\\ \\& = \sf 14 \end{aligned}[/tex]
Therefore, Navya can make 14 pairs of earrings.
