There ya go. The numbers of possible amounts of mangos he could buy without exceeding his budget.
The possible values of mangos if, The cost of peaches is $2, The cost of the mangos is $1.25, and the Total money is $20, are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
What is equation?
A formula known as an equation uses the equals sign to denote the equality of two expressions. In other terms, it is a mathematical statement stating that "this is equivalent to that."
Given:
The cost of peaches =$2,
The cost of the mangos = $1.25,
Total money = $20,
Write the equation, if Henry buys 10 peaches,
10 × 2 + 1.25x = 20
Here, x is the number of mangos,
1.25x = 20 - 20
x = 0
Write the equation when Henry buys 4 peaches,
4 × 2 + 1.25x = 20
8 + 1.25x = 20
x = 20 - 8 / 1.25
x = 9.6 or 9 mangos
Thus, Henry can buy a maximum of 9 mangos if he buys at least 4 peaches.

which numbers the additive inverse of -41/4
Answer:
The answer is 41/4.
Step-by-step explanation:
Given:
-41/4 to get the additive inverse.
Now, the additive inverse of any number is a number that, when added to the number the result is zero.
Here, 41/4 is the additive inverse.
Because when it is added to -41/4 the result is 0.
Therefore, the answer is 41/4.
Choosing a number from 1 to 10 what is the probability of choosing a number less than 3?
About 2% chance.
There are ten numbers and you want to choose a number less than three. There are only two numbers less than three; 1 & 2. Because there are only 2 numbers less than three and 10 to choose from, it becomes a 2% chance.

To solve for y in the equation 2 x + y = 5, subtract 2 from both sides of the equation.
True False
Answer:
False.
Step-by-step explanation:
Because we have to isolate y and subtracting 2 will not put y alone on one side.
We have to subtract 2x in order to solve for y.
Answer:
False
Step-by-step explanation:
To solve this equation 2x + y = 5, you need another pair equation with the same variables, or one of the variables (x or y) need to be known to solve this equation.
Or you need to subtract 2x from both side to make y subject of formula.
Find the points at which the graph of the equation -4y=15-5x crossed the x- axis and the y - axis.
Answer:
see explanation
Step-by-step explanation:
Where the graph crosses the x- axis the y- coordinate is zero.
Let y = 0 in the equation and solve for x
- 4(0) = 15 - 5x, that is
15 - 5x = 0 ( subtract 15 from both sides )
- 5x = - 15 ( divide both sides by - 5 )
x = 3 ← x- intercept ⇒ (3, 0 )
Where the graph crosses the y- axis the x- coordinate is zero.
Let x = 0 in the equation and solve for y
- 4y = 15 - 5(0), that is
- 4y = 15 ( divide both sides by - 4 )
y = - [tex]\frac{15}{4}[/tex] ← y- intercept ⇒ (0, - [tex]\frac{15}{4}[/tex])

Step-by-step explanation:
Hello!
Product means to multiply.
Which means it’s x added by itself y times.
For this problem it means 8 added by itself 12 times.
You can do:
8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8, which equals 96.
Or, 8 x 12.
Which is 96.
It still represents 8 + 8, etc.
But your doing it faster.
Therefore, your Product is 96.

The expression 4⁵ × 4⁻⁷ divided by 4⁻² simplifies to 1 by using the properties of exponents. First, add the exponents in the numerator, then subtract the exponents for division, resulting in 4⁰, which equals 1.
We need to simplify the expression:
4⁵ times 4⁻₇ ext{ divided by } 4⁻²
To simplify, let's first combine the powers of 4 in the numerator:
Using the property that when multiplying like bases, we add the exponents:= 4⁵ times 4⁻⁷
= 4⁽⁵⁺⁽⁻⁷⁾⁾
= 4⁻²
Next, address the division with a like base, which subtracts the exponents:= 4⁻² ext{ divided by } 4⁻²
= 4⁽⁻²⁻⁽⁻²⁾⁾
= 4⁽⁻²⁺²⁾
= 4⁰
Any number raised to the power of 0 is 1:4⁰ = 1
Therefore, the given expression simplifies to 1.

The population of Collin County, which follows the exponential growth model, increased from 491,675 in 2000 to 782,341 in 2010. Find the exponential growth rate, k.
Answer:
p=ak^t
p1=491272*k^0
p2=782341*k^10
782341/491272 = k^10
k=1.047629
growth rate is 4.7629%
2012: predicted population is 491272*1.047629^12=858,642 people
1245863=491272*1.047629^t
1.047629^k=2.5363599
ln both sides is k ln 1.0476=ln 2.5363
t=20.000 years.
Rule of 72 would say 72/4.76 or 15.12 years for doubling
14.90 years
2017 predicted is 491272*1.0476^17 or 1083552, or more than actual, so the rate of growth is slowing down.

p₂=782341*k¹⁰
782341/491272 = k¹⁰
k = 1.047629
So, the growth rate is 4.7629%
2012: the predicted population is 491272 × 1.047629¹² =858,642 people
1245863=491272 × [tex]1.047629^t[/tex]
[tex]1.047629^k[/tex] = 2.5363599
ln both sides is k ln 1.0476 = ln 2.5363
t = 20.000 years.
Rule of 72 would say 72/4.76 or 15.12 years for doubling
14.90 years
2017 predicted is 491272 × 1.0476¹⁷ or 1083552, or greater than the real rate of increase, hence the rate of growth is decreasing.

Answer:
a = 108° and b = 144°
Step-by-step explanation:
The opposite angles of a rhombus are the same and the sum of all the angles of the rhombus is 360°.
So, from the given diagram of the rhombus we can write
2b + 2× 36 = 360
⇒ 2b = 360 - 72 = 288
⇒ b = 144° (Answer)
Again, the each angles of a pentagon is given to be a.
Hence, we can write 3a + 36 = 360
⇒ 3a = 324
⇒ a = 108° (Answer)
Let's say you opened your laptop and positioned the
screen so it's exactly at 90° - a right angle - from your
keyboard. Now, let's say you could take the screen and
push it all the way down beyond 90°, until the back of the
screen is flat against your desk. It looks as if the angle
disappeared but hasn't. What is the angle called, and
what is the measurement?
A. Straight angle at 180°
B. Linear angle at 90°
C. Collinear angle at 120°
D. Horizontal angle at 180°
it will surely look like an angle on a straight line. which adds up.to 180,so the answer is horizontal angle at 180degrees
Final answer:
The correct answer is A. Straight angle at 180°, describing the angle formed when a laptop screen is moved from a 90° position to lying flat against the desk.
Explanation:
The question asks about the angle formed when a laptop screen is opened from a right angle (90°) to lying flat against the desk, covering a full range from vertical to horizontal. This describes a straight angle, which measures 180°. Initially, the laptop screen at a 90° angle to the keyboard represents a right angle. Pushing the screen down to lie flat transitions this to a straight angle, where the angle between the keyboard and the back of the screen spans a flat, straight line. Therefore, the correct answer is A. Straight angle at 180°.

what is 8/9 times 5/7 times 1/8 as a fraction in simplest form

5/63
Step-by-step explanation:
8/9(5/7)(1/8)=
8/9(5/7)=
40/63(1/8)=
5/63
by the way 8/9 x 5/7 x 1/8
is also the same as (8/9)(5/7)(1/8)
To find the product of 8/9, 5/7, and 1/8, multiply the numerators and denominators to get 40/504 and simplify it to 5/63.
Explanation:To solve the multiplication of fractions, we need to multiply the numerators together and the denominators together. For the expression 8/9 times 5/7 times 1/8, we multiply the numerators 8, 5, and 1 to get 40, and the denominators 9, 7, and 8 to get 504. Simplifying the fraction 40/504 involves finding the greatest common divisor, which is 8 for both numerator and denominator, and dividing them by this number.
Doing so, we get 40 ÷ 8 = 5 and 504 ÷ 8 = 63. Hence, the solution simplified is 5/63.

The sine ratio of an angle is the opposite side over the adjacent side.
always
never
sometimes
Answer:
never
Step-by-step explanation:
In a right triangle, every angle has an opposite side and an adjacent side. And there's always a hypotenuse.
The sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse.
The tangent ratio of an angle is the opposite side over adjacent side, it is not the sine ratio of a triangle.
For example, ABC is a right angled triangle having length of the sides are a,b,c.
So
[tex]sine\ C=\frac{a}{c}[/tex]
The sine ratio of an angle sometimes is the opposite side over the adjacent side.
The question pertains to the definition of the sine ratio in trigonometry. The sine ratio of an angle is not defined as the opposite side over the adjacent side; rather, it is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse of a right-angled triangle.
Therefore, the correct statement is the sine ratio of an angle sometimes is the opposite side over the adjacent side, specifically in the case of a 45°-45°-90° triangle where the sides are equal, but this is not generally true for all angles in trigonometry.
