Answer:
Step-by-step explanation:
1. 34 animals because of 34 heads.
94 legs: 4 per cow, 2 per chicken
x= # of cows
y= # of chickens
so x+y=34
4x+2y=94
Multiply the first equation by -2 is -2x-2y=-68 and add it to the first equation.
which is 2x=26. so x=13. Since x+y=34, 13+y=34.
Therefore, y=21
13 cows and 21 chickens.
2. lets say
pizza=y
soda=x
6x+x=14 combine like terms
7x=14 divide both sides by 7
x=2
So a soda is $2.
6*2=12. So the pizza is $12.
12+2=14. So it's correct.
3.
# of DVDS=x
# of Bluray= y
11x+17y=95
x+y=7
dvds-4
blu-ray-3 (I just did trial and error, but it's correct)
4.
# of 2-points= x
# of 3-points= y
2x+3y=18
2(6)+3(2)=18
so 6 two-point shots and 2 three-point shots.
5.
12 coins are quarters and 14 are dollar coins.
let q stand for the number of quarters
and 26 coins in total
26-q= dollar coins
x=dollar coins too
so its 1x+.25(26-x)=17
1x+6.5-0.25x=17
.75x+6.5=17
.75x=10.5
x=14
17-14=3
3*4= 12 since 4 quarters in a dollar.

Is Jenny's percentage correct?

Answers
Answer:
Jenny's percentage isn't correct
Step-by-step explanation:
You'd have to divide first:
38 / 32 = 1.1875 = (rounded) 1.19%
The percentage increase is 1.19%
Answer:
the percentage is 100 because you add 32 and 38 and equals 100 if you were to subtract you would have got 6%
Which angle in ABC has the largest measure?
Answers
Answer:
Angle B
Step-by-step explanation:
Angle B because the measure of angle B is 12 . Angle A has a measure of 7 and angle C has a meausre of 10 which both measures of the angles are less than angle B. Think of it like this... 17 people (7+10) went to a Bakery. There were only 7 cupcakes and 10 sweet potato pies. To start with there were 35 cupcakes and 35 sweet potato pies. 7 people ordered cupcakes and 10 people ordered sweet potato pie. There were 18 left of the 2 deserts. 18 is greater than 7 and 10. That´s why angle B is the angle that has the largest measure. 12 is greater than 7 and 10. If there were only 7 milkshakes left and 10 people wanted a milkshake, only 7 people would be able to get a milkshake. 3 people wouldn´t be able to get a milkshake
So angle B is the correct answer.
Answer: angle b

Given Z1= 5 – 2i and z2 = 3 + 2i, which letter
represents Z1-Z2
A
B
C
D
Answers
Answer:
I believe it is A
Step-by-step explanation:
When you subtract z1 from z2, you get 2-4i, which on the graph is point A.
Point A represents 2-4i in the graph given. Therefore, option (1) is the correct answer.
Given that, [tex]z_{1}=5-2i[/tex] and [tex]z_{2}=3+2i[/tex].
We need to find the value of [tex]z_{1}-z_{2}[/tex].
What are complex numbers?A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane.
Now, [tex]z_{1}-z_{2}[/tex]=5-2i-(3+2i)
=5-2i-3-2i
=2-4i
Here, 4i is the imaginary and 2 real numbers.
Point A represents 2-4i in the graph given. Therefore, option (1) is the correct answer.

Step-by-step explanation:
Makes the most sense-
The y value goes down one, which makes it negative and if u go along the x line it goes over 4 and sense it goes to the right, it would be positive.
I don’t know if I am supposed to substitute the x variable in f(x) or leave the f(x) the same.

Find three consecutive integers such that the sum of twice the second and four times the third is twenty-five more than the first?
Answers
Answer:
3, 4, 5
Step-by-step explanation:
Three consecutive integers means that
[tex]X_1, X_2 = X_1 + 1, X_3 = X_2 + 1[/tex]
The sum of twice the second and 4 times the third is 25 times the first number
[tex]X_1 + 25 = 2X_2 + 4X_3\\X_1 + 25 = 2(X_1 + 1) + 4(X_1 + 2)\\X_1 + 25 = 2X_1 + 2 + 4X_1 + 8\\X_1 + 25= 6X_1 + 10\\5X_1 = 15\\X_1 = 3\\X_2 = 4, \\X_3 = 5[/tex]

Given that the radius of the circle is
2 yd.
Answers
Step-by-step explanation:
Area of first triangle = 1/2bh
the base of the triangle = the radius of the semi-circle = 2yd
height = 5yd
Area = 1/2(5yd)(2yd)
A = 5yd(yd)
A = 5y^2d^2 squared units.
since the second triangle also has the same dimensions as the first triangle
hence:
Area of the second triangle = 5y^2d^2 squared units.
Area of semi-circle = πr^2
Area = π(2yd)^2
A = 4πy^2d^2 squared units

In 2010, the population of China was around 1.400,000,000 and growing
at a rate of 1.65% per year. What should the population be this year?*
Answers
Answer:
1423100000
Step-by-step explanation:
1.65% of 1.4 billion is 23,100,000. Knowing this you just add the two numbers together to find what an extra 1.65% of people being added to the population would result in.
The current population of China is 1,423,100,000 using the compound rate of increment method.
What is a compound rate of increment?The compound rate of increment is a type of increment that is compounded after time period it is said to be compounded. After that particular period, the increment is calculated and then added with the primary number. For the next duration, the increment is calculated on the sum.
Given, the total of population of China in 2010 was (P) = 1,400,000,000.
The rate of increase of population is (r) = 1.65%
Duration (n) = (2022 - 2010) years = 12 years.
Therefore, the total of population of China in 2022 (S)
= P(1 + r)ⁿ
= 1,400,000,000(1 + 1.65/100)¹²
= 1,400,000,000(1 + 0.0165)¹²
= 1,400,000,000(1.0165)¹²
= 1,423,100,000
Therefore, the population of China in 2022 is 1,423,100,000.
