Hey you ‼️ yeah I unfortunately need your help again these are hard:(
Answer:
Step-by-step explanation:
The point of this question is to find out the point where two lines intersect. First we need to get the equation of those lines
Slope of line 1:
(Yb -Ya)/(Xb - Xa) =
(-10 - (-14))/(-1 - (-3)) =
4/2 =
2
Use that slope to find the Y-intercept of line 1
y = 2x + b
-14 = 2(-3) +b
-14 = -6 + b
-8 = b
Therefore Line 1 is:
y = 2x - 8
Slope of line 2
(11 - 13)/(-1 - (-3)) =
-2/2 =
-1
Y-intercept of line 2
y = -x + b
13 = -(-3) +b
13 = 3 + b
10 = b
Therefore line 2 is
y = -x + 10
Now we have 2 equations to solve for the coordinates x and y
y = 2x - 8
y = -x + 10
Substitute y out in one of the equations
2x - 8 = -x + 10
3x = 18
x = 6
Plug x into one of the equations
y = 2(6) - 8
y = 12 - 8
y = 4
Therefore the solution is:
x=6, y=4

3/4 cups of sugar for every 3/8 teaspoon of cinnamon what is the unit rate of cups per teaspoon
Answer:
2 cups per teaspoon
Step-by-step explanation:
3/4 cups of sugar for every 3/8 teaspoon of cinnamon what is the unit rate of cups per teaspoon
From the question:
3/4 cups = 3/8 Teaspoons of cinnamon
the unit rate of cups per teaspoon is calculated as:
3/4 cups÷ 3/8 teaspoons
= 3/4 ×8/3
= 2 cups per teaspoon

Michael is 25 years younger than his father. The sum of their ages is 53. What is Michael's age?
Answer:
14
Step-by-step explanation:
Answer:
Micheal is 14
Step-by-step explanation:
First you need to minus the 25 from 53 to see how old they both are without the age difference, 53-25=28. Since we are looking at 2 people, we need to divide this number by 2. From this we get 14. Now 14+25=39. So we can prove that our answer is valid. Ergo, Micheal's age is 14.

25 POINTS. Radar used microwaved yo check the speed of cars. If a speed of the microwaves is 2 000 000 m/ s and the wavelength is 0.0345m calculate the frequency.
Answer:
57971014.49 Hz or 5.79 * 10^7 Hz
Step-by-step explanation:
Given that:
Speed of microwave (v) = 2,000,000 m/s
Wavelength, λ = 0.0345 m
Frequency :?
Using the relation :
v = fλ
f = v / λ
f = 2,000,000 / 0.0345
f = 57971014.49 Hz

Peter went to a local zoo where 30% of the exhibits feature canines. If the zoo features a total of 27 exhibits, how many of the zoo exhibits feature canines? Round your answer to the nearest whole number if necessary.
Answer: 8 exhibits
Step-by-step explanation:
There are 27 exhibits in this zoo.
Out of these 27, 30% of them feature canines.
The question is asking for this percentage as a whole number:
= Percentage of exhibits with canines * total number of exhibits
= 30% * 27
= 8.1
= 8 exhibits
need help which one is it
a)x=7
b)x=12
c)x=20
- you can use the pythagorean theorem for this.
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
- square root this.
c = 20
therefore, x = 20.
so option C.
Answer:
c. X = 20
Step-by-step explanation:
Pythagoras theorem
a² + b² = c²
12² = 144
16² = 256
144 + 256 = 400
√400 = 20
A company makes cars.
The company’s income in 2017 was $500 000 more than the company’s income in 2016
The company’s income in 2017 was 8% more than the company’s income in 2016
Work out the company’s income in 2016?
Answer:
$6,250,000
Step-by-step explanation:
Let :
2016 income = x
2017 income = x + $500,000
2017 income is 8% more than company's income in 2016
Thus ;
8% of 2016 income = 500000
0.08x = 500,000
x = 6,250,000
Hence, the company's income in 2016 is $6,250,000

terri is planning to build a garden using the plans below. how much fencing will she need to split the garden on the diagonal? rectangular 40yards by 30yards
Answer:
Length of the fence is 50 yards.
Step-by-step explanation:
The dimensions of the garden are:
length of the garden = 40 yards
width of the garden = 30 yards
Representing these by the sides of a right angled triangle, the diagonal is the hypotenuse of the triangle. So that applying the Pythagoras theorem, we have:
[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
Let the diagonal be represented by x, so that;
[tex]x^{2}[/tex] = [tex]40^{2}[/tex] + [tex]30^{2}[/tex]
= 1600 + 900
= 2500
x = [tex]\sqrt{2500}[/tex]
= 50
x = 50 yards
Hence, Terri would need a fence of length 50 yards so as to split the garden on the diagonal.
