Amaya's test scores in algebra 1 are 78 and 91. She has one more test left and wants to earn a B for the course, which is from 80-89 inclusive
Answer:
Amaya must get marks between 71 and 98 in order to get B grade
Step-by-step explanation:
Amaya's test scores in algebra 1 are 78 and 91.
Let she got x marks in third test
The average all the three test must be 80-89
i.e. [tex]80\leq\dfrac{78+91+x}{3}\leq 89[/tex]
Multiplying all sides by 3, we get
240≤ 78+91+x≤ 267
240≤ 169+x≤ 267
Subtracting all sides by 169, we get
71≤ x≤ 98
Hence, Amaya must get marks between 71 and 98 in order to get B grade

The helvie family drinks 1 3/4 gallons of milk every 4 1/2 days. what is the unit rate of milk they drink per day?
he Mitchell family is renting a boat for the day. The boat rental has a flat fee of $100 plus $20 for each hour. They have to pay for a whole hour even if they are not out on the lake for a whole hour. For example, if they rent the boat for 3 and one-half hours, they have to pay for 4 hours. If they want to spend $250 or less on the boat rental for the day, how many hours can they rent the boat? Write an inequality and solve.
250-100 = 150
150/20 = 7.5
7 hours
inequality: 100+20x <=250
They can rent the boat for 7 hours for $ 240 in total.
Since the Mitchell family is renting a boat for the day, and the boat rental has a flat fee of $ 100 plus $ 20 for each hour, and they have to pay for a whole hour even if they are not out on the lake for a whole hour, to determine, if they want to spend $ 250 or less on the boat rental for the day, how many hours can they rent the boat, the following calculation must be performed:
Fixed cost + Variable cost multiplied by the number of hours = Final cost 100 + 20X = 250 20X = 150 X = 150/20 X = 7.5 100 + 20 x 8 = 100 + 160 = 260 100 + 20 x 7 = 100 + 140 = 240
So they can rent the boat for 7 hours for $ 240 in total.

A vineyard has 165 acres of chardonnay grapes. a particular soil supplement requires 6.00 grams for every square meter of vineyard. how many kilograms of the soil supplement are required for the entire vineyard? (recall that 1 km2 = 247 acres)
Answer:
4008.10 kg
Step-by-step explanation:
We have been given that a vineyard has 165 acres of chardonnay grapes. a particular soil supplement requires 6.00 grams for every square meter of vineyard.
We know that 1 squared km equals 247 acres.
[tex]\text{165 acres}\times\frac{\text{1 km}^2}{\text{247 acres}}[/tex]
[tex]165\times\frac{\text{1 km}^2}{247}[/tex]
[tex]0.6680161943319838\text{ km}^2[/tex]
We know 1 square km equals 1000000 meters.
[tex]0.6680161943319838\text{ km}^2\times \frac{1000000\text{ m}^2}{\text{ km}^2}[/tex]
[tex]0.6680161943319838\times 1000000\text{ m}^2[/tex]
[tex]668016.1943319838\text{ m}^2[/tex]
Now, we will multiply 6 by [tex]668016.1943319838\text{ m}^2[/tex].
[tex]668016.1943319838\text{ m}^2\times \frac{\text{6 grams}}{\text{m}^2}[/tex]
[tex]668016.1943319838\times \text{6 grams}[/tex]
[tex]4008097.1659919028\text{ grams}[/tex]
[tex]4008097.1659919028\text{ grams}\times \frac{1\text{ kg}}{\text{1000 grams}}[/tex]
[tex]4008.09716599190281\text{ kg}[/tex]
[tex]4008.10\text{ kg}[/tex]
Therefore, 4008.10 kg of the soil supplement are required for the entire vineyard.

The coordinates of the endpoints of and are A(3, 6), B(8, 7), C(3, 3), and D(8, 4). Which statement describes how and are related?
a)AB//CD
b)AB//CD, and AB bisects CD
c)AB//CD, but AB does not bisect CD
d)AB is neither parallel nor perpendicular to CD
Answer:
The correct answer is option a.
Step-by-step explanation:
If a line passing through two points, then the slope of a line is defined as
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The coordinates of the endpoints of are A(3, 6), B(8, 7), C(3, 3), and D(8, 4).
[tex]m_{AB}=\frac{7-6}{8-3}=\frac{1}{5}[/tex]
[tex]m_{CD}=\frac{4-3}{8-3}=\frac{1}{5}[/tex]
Since slope of AB and CD are same, therefore the line AB is parallel to CD because the slope of parallel lines are equal.
Two parallel lines never intersect each other, therefore AB does not intersect CD. Only option a is correct.

d=f+fx , solve for x
To solve for x means we make x the subject of the formula. The value of x is:
[tex]x = \frac{d - f}{f}[/tex]
Given that:
[tex]d = f + fx[/tex]
To solve for x, we make use of the following steps
[tex]d = f + fx[/tex]
Subtract f from both sides
[tex]d - f =fx[/tex]
Isolate x: Divide both sides by f
[tex]\frac{d - f}{f} = x[/tex]
So, we have:

Which of the following numbers is irrational? a fraction with numerator negative 9 and denominator 5, a fraction with numerator square root of 5, a fraction with numerator 7 and denominator 3, square root of 9
Answer:
The answer is square root of 5.
Step-by-step explanation:
Irrational numbers are those that cannot be expressed as a ratio of two integers.
And when we express these in decimal form, they have an infinite and nonrecurring expansion like the number π and the square root of 2.
The answer is square root of 5. This is because the square root of 5 will never result in a number that will be exact.
The pitcher for the robins throws a baseball at 90.0 miles per hour. The pitcher on the bluebirds throws a baseball 121 feet per second. Which pitcher throws a baseball faster?
Answer:
The pitcher of robins throws a baseball faster.
Step-by-step explanation:
Speed of base ball thrown by the pitcher for the robins = 90.0 mile/hour
1 mile = 5280 feets
1 hour = 3600 seconds
[tex]90.0 mile/hour=\frac{90.0\times 5280 feet}{3600 s}=132 feet/s[/tex]
Speed of base ball thrown by the pitcher for the bluebirds= 121 feet/s
132 feet/s > 121 feet/s
The pitcher of robins throws a baseball faster.
How many years difference is there between 250 ce and 250 bce?
There are 500 years between 250 CE and 250 BCE
Years that are denoted as BCE are counted backwards until they get to 0 after which years are then denoted as CE and these ones count upwards.
This means that to find the difference between these two years, you must first count from 250 BCE to 0 and then from 0 to 250 CE.
250 BCE to zero = 250 years
Zero to 250 CE = 250 years
Then sum them up:
= 250 + 250
= 500 years
There is therefore a difference of 500 years between these two years.
