90 degrees
180 degrees
270 degrees
Answer:
180 degrees

Jose starts with $250 and spends $25 a week. Martin starts with $30 and saves $30 a week. When do Jose and Martin have the
same amount of money? Use x for time and y for saving.
Answer:
4 weeks, Jose and Martin will have the same amount of money in 4 weeks which is $150 each
Step-by-step explanation:
Jose:
y = -25x +250
Martin:
y=30x+30
Substitute x= 6 into the two equations
Jose:
y = -25(6) + 250
= -150+250
y = 100
Martin:
y = 30(6) +30
=180+30
y = 2100
Substitute x=4 into the two equations
Jose:
y = -25(4) + 250
=-100+250
y = 150
Martin:
y = 30(4) + 30
=120+30
y = 150

Answer:
100^2
Step-by-step explanation:
I believe it is 100 because one square is 10 times 5 which equals 50 since A=bh. If we multiply 50 times 2 or do the same for the other square and add the two areas together. We got 100^2.

Mr. Whittaker’s science class uses tide gauges to measure annual variations in water levels at different parts of a river, and then compares those variations to the average annual trend.
Matea recorded that the water level in one part of the river fell 1.05 millimeters per year for 2.48 years.
Which number represents the rate at which the water level fell? -1.05mm/year
Which number should the rate be multiplied by to find the total variation in water level?
2.48 years
that's the correct answer ^
This data will be compared to the average annual trend, which shows the water level rising 1.8 mm/year.
Which number represents the rate at which the water level fell?
Which number should the rate be multiplied by to find the total variation in water level?
Answer:
a) Which number represents the rate at which the water level fell? -1.05mm/year
b) Which number should the rate be multiplied by to find the total variation in water level?
2.48 years
Step-by-step explanation:
Total variation in water level is calculated as the rate at which the water level fell multiplied by number of years are which the water level fell.
Mathematically = Rate at which the water level fell(mm/year) × number of years are which the water level fell (years).
Total variation in water levels can be caused by changes in climate conditions or by human activity.
Hence, for the question above,
rate at which the water level fell is
given as -1.05mm/year and the number that the rate be multiplied by to find the total variation in water level is 2.48 years.
Answer:
Which number represents the rate at which the water level fell?
✔ -1.05 mm/year
Which number should the rate be multiplied by to find the total variation in water level?
✔ 2.48 years

In which type of triangle is the othocenter on the perimeter of the triangle?
A.) a right triangle
B.) an a cute triangle
C.) an obtuse triangle
D.) an equilateral triangle
Answer:
A right triangle
Step-by-step explanation:
It's where the altitudes all intersect. In a right triangle, the legs of the right triangle are the altitudes-- especially evident when the right angle is at the base. The altitude from the hypotenuse to the right angle also passes through the right angle.

Em uma caixa há 11 bolas vermelhas e 7 azuis. Ao escolher 4 bolas aleatoriamente, qual a probabilidade de serem todas vermelhas? (A) 1 7 . (B) 7 102. (C) 11 102. (D) 7 18 (E) 11 18
Answer: C. 11/102
Step-by-step explanation:
Given Data:
Red ball = 11
Blue ball = 7
Total no of balls = 18
What is the probability that choosing 4 balls all are red.
1. Probability of picking a red ball
= 11/18
2. Probability of picking a blue ball
= 7/18
3. Probability of picking 4 red balls in a roll.
= 11/ 18 * 10/17 * 916 * 8/15
= 11/102
Or
10.8% chance of all 4 balls being red.

Amanda is making flower arrangements. She has 20 daisies and 16 roses. Each arrangements must hhave the same number of daises and same number of roses. She wants to use all the flowers. What is the greatest number of arrangements she can make? How many daisies and how many roses will be in each?
Answer:
The greatest number of arrangements she can make would be that she uses 4 groups of 5 daisies and 4 groups of 4 roses.
The greatest number of arrangements is 4, and each group has 5 daises and 4 roses.
What is the greatest common divisor?The biggest positive integer that divides both numbers and is a divisor of both is known as the greatest common divisor of two integers.
Given that, Amanda has 20 daises and 16 roses.
The number of arrangements that can be made using 20 daises and 16 roses is the greatest number that can divide both the numbers 20 and 16.
The greatest number that can divide both 20 and 16 is 4.
Hence, 4 groups of arrangements can be made.
The number of daises in a group is:
20/4
= 5
The number of roses in a group is:
16/4
= 4
Hence, the greatest number of arrangements is 4, and each group has 5 daises and 4 roses.

A contractor bought 8.2 ftsquared of sheet metal. She has used 3.5 ftsquared so far and has $141 worth of sheet metal remaining. The equation 8.2xminus3.5xequals141 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer:
The cost of a sheet metal per square foot is $30
Step-by-step explanation:
Given
Size of Sheet Metal = 8.2ft squared
Used Sheet Metal = 3.5ft squared
Worth of leftover sheet = $141
Equation: [tex]8.2x - 3.5x = 141[/tex]
Required
Find the cost per square foot of the sheet metal
Solving for x in the above equation will give the cost per square foot of the sheet metal.
[tex]8.2x - 3.5x = 141[/tex]
[tex]4.7x = 141[/tex]
Divide both sides by 4.7
[tex]\frac{4.7x}{4.7} = \frac{141}{4.7}[/tex]
[tex]x = \frac{141}{4.7}[/tex]
[tex]x = 30[/tex]
Hence, the cost of a sheet metal per square foot is $30

Jo is going to a college where the cost for one year is $11,000. He has a scholarship worth $5,000. He earns $200 a week at his job. How many weeks does he need to work to pay for 50% of the remaining amount?
Answer:
15 Weeks
Step-by-step explanation:
$11,000 - $5,000 = $6,000 This is how much he needs to pay.
$6,000 ÷ $200 = 30 This is how many weeks he needs to work to get the $6,000
The questions is asking how many weeks does he have to work to get %50, Therefore 30 x .50 = 15 which is your answer.

Clara simplifies (8 b minus 4 r) minus (2 b minus r) and says the result is 6 b minus 5 r. What error did Clara make? Clara incorrectly combined the b coefficients. The correctly simplified expression is 10 b minus 5 r. Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r. Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b + 5 r. Clara incorrectly combined the b coefficients. The correctly simplified expression is Negative 10 b minus 5 r.
Answer:
Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.
Step-by-step explanation:
