Combining like terms: -23x + 9y
pls help me with this multiple choice !
Answer:
A
Step-by-step explanation:
since the angles are 45,45 the triangle is an Equilateral triangle
V=12
[tex] {u}^{2} = {12}^{2} + {12}^{2} \\ {u}^{2} = 288 \\ u = \sqrt{288} = 12 \sqrt{2} [/tex]
Which equation can be used to solve for x in the following diagram?
7xº
11x°
Answer:
7x° + 11x° = 90°
(Required equation)
Step-by-step explanation:
7x° + 11x° = 90°
(complementary angles)
18x° = 90°
18x = 90
x = 90/18
x = 5

20. Isosceles trapezoid LMNO has vertices L(-4,-3), M(-4,0), N(-2, 1),and O(-2,-4). If the figure is
dilated with the center at the origin and with a scale factor of 1.5, what is the length of L'M' of the
dilated isosceles trapezoid?
Answer:
L’M’ = 4.5 units
Step-by-step explanation:
We start by getting the dilated coordinates
we specifically work with the points LM
The dilated points can be obtained by multiplying the individual coordinates by 1.5
for L (1.5 * -4 and 1.5 * -3) = L’ (-6, -4.5)
M (-4,0) and ; (1.5 * -4 and 0 * 1.5) = M’ (-6,0)
Now, we can use the distance formula
D = √(y2-y1)^2 + (x2-x1)^2
D = √(0+ 4.5)^2 + (-6+6)^2
D = √(4.5)^2
D = 4.5 units

Answer:
Question 1: g = 6
Question 2: v = 84
Question 3: y = 60
Question 4: w = 496
Question 5: Kyle had $400 to begin with.
Step-by-step explanation:
Question 1 explanation: 12g = 72 ⇒ g = [tex]\frac{72}{12}[/tex] = 6
Question 2 explanation: [tex]\frac{v}{4}[/tex] = 21 ⇒ v = 21 * 4 = 84
Question 3 explanation: [tex]\frac{1}{6}[/tex] y = 10 ⇒ 6 * [tex]\frac{1}{6}[/tex] y = 10 * 6 ⇒ y = 60
Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496
Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.

Biologists estimate deer populations by sampling a small area and using that information to estimate the entire
population of a large area. They use the equation p= na to estimate p, the population of deer in a acres of land, where
n is the number of deer per acre determined from the sampling. A biologist determines that 1,800 deer populate an area
of 150 acres. What value of n did the biologist find in the initial sampling of the population?

People attending a basketball game either supported the home team or the visiting team. If 549 of the people attending supported the home team and 351 supported the visiting team, what percentage supported the home team?
People who supported the home team= 549
People who supported the attending team= 351
Total no. of audience= 549+ 351
= 900
Percentage of home team=
(549/900× 100)
= 61%

HELP ME ANSWER A AND B
Answer:
a) 4c+3b=11.67
8c+b=12.89
b)One loaf of bread cost $2.09
One can of soup costs $1.35
Step-by-step explanation:
Let c= can of soups Let b= loaf of bread
a) To find the equation, you know that Khalil buys four cans of soup and 3 loafs of bread and 4 cans of soup for $11.67 so that means that the first equation will be 4c+3b=11.67. Then, you know that Khalil buys 8 cans of soup and one bread for $12.89. so the next equation will be 8c+b=12.89. This means the system of linear equations will be
4c+3b=11.67
8c+b=12.89
b) Use elimination to solve this. You want to make one variable from each equation the same so multiply 4c+3b=11.67 by 2. This will look like 2(4c+3b=11.67). Then simplify to get 8c+6b=23.34 and 8c+b=12.89. Because 8 and 8 are the same, you have to subtract the equations from each other making 5b=10.45. Simplify that and you get b= 2.09 so the one loaf of bread cost $2.09. Then plug 2.09 into 8c+b=12.89. It will look like this 8c+2.09=12.89. Simplify that and you get 8c=10.8. Simplify that again and you will get 1.35 so a can of soup will costs $1.35
Therefore
a) 4c+3b=11.67
8c+b=12.89
b) One loaf of bread cost $2.09
One can of soup costs $1.35

Suppose a local park is rectangular in shape and has a length of 210 yards and a width of 105 yards. What is the length of the diagonal of the park? Round your answer to the nearest hundredth of a yard.
Answer:
234.784 ~ 235
Step-by-step explanation:
One side = 210
other side = 105
a2+b2 = c2
210 ^2 + 105 ^2 = c2
55125 = c ^2
c = [tex]\sqrt{55125}[/tex] = 234.784 ~ 235

The reason why the deaths and recoveries occurs so rapidly in the pandemic
Answer:
As time goes by the virus expands, and evolves causing more people to get infected. Although people who have made it before when the virus had affected them do not get affected by the evolved virus. People who have weak immune systems when infected die. Therefore, the reason thatthe deaths and recoveries happen to rappidly is because of the virus evolving, when some people are able to withstand it whilst others die.
Hope this helped.
