Answer:
Part A: 60
Part B: Each cup of coffee costs 2.5 dollars
Part C: Each donut costs 1.75 dollars
Part D: Sonario spent 123.75 dollars in coffee and donut holes
Part E: The number of cups of coffee bought are 25 cups of coffee
The number of donut holes bought are 35 donut holes
Step-by-step explanation:
The given parameters are;
c + d = 60
2.5 × c + 1.75 × d = 123.75
Part A
Whereby the number of cups of coffee bought = c, and the number of donut holes bought = d, then, the total number of cups of coffee and donuts bought is c + d = 60
Part B:
From the second equation for the total cost of cups of coffee and holes of donuts, the coefficient multiplying the variable representing an item is the cost of the item
Therefore, each cup of coffee costs 2.5 dollars
Part C:
Using the method from above, each donut costs 1.75 dollars
Part D:
From the equation for the total cost, Sonario spent 123.75 dollars in coffee and donut holes
Part E:
By the elimination method, we have;
c + d = 60
∴ c = 60 - d
Eliminating c in the equation for the total cost gives;
2.5 × c + 1.75 × d = 2.5 × (60 - d) + 1.75 × d = 123.75
150 - 2.5·d + 1.75·d = 150 - 0.75·d = 123.75
150 - 123.75 = 0.75·d
26.25 = 0.75·d
d = 26.25/0.78 = 35
d = 35
c = 60 - d = 60 - 35 = 25
c = 25
∴ c = The number of cups of coffee bought = 25 cups of coffee
d = The number of donut holes bought = 35 donut holes
Find the distance between the points (-3,7)
and
(6, 7).
Answer:
9
Step-by-step explanation:
use the distance formula:
[tex]\sqrt{(x2 -x1)^{2} + (y2-y1)^{2} }[/tex]
so, with your two points, x2=6, x1=-3, y2=7, and y1=7
so then just plug in the values
[tex]\sqrt{(6--3)^{2} + (7-7)^{2} }[/tex]
because you have 6 minus a negative number, it turns into 6+3, like shown
[tex]\sqrt{(6+3)^{2} + (7-7)^{2} }[/tex]
so then add and subtract the parenthesis
[tex]\sqrt{(9)^{2} + (0)^{2} }[/tex]
so then because 0 squared is just zero, you simply have the square root of 9 squared
[tex]\sqrt{9^{2} }[/tex]
so then square the 9
[tex]\sqrt{81}[/tex]
then take the square root of 81, and you get 9!
[note that when you have the square root of a squared number, it is just the number, so the square root of 9 squared is just 9, but if it helps, you can work it out like I did to show you :)]
The distance between the points (-3, 7) and (6, 7) is 9.
What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
Where (a, b) and (c, d) are the two points.
We have,
(-3, 7) = (a, b)
(6, 7) = (c , d)
Now,
Distance between these two points.
= [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
= √(6 + 3)² + (7 - 7)²
= √9²
= 9
Thus,
The distance between the points is 9.

Function k is a continuous quadratic function that includes the ordered pairs shown in the table.
Over which interval of the domain is the function increasing?
i didnt mean to click B btw
Answer:
B
Step-by-step explanation:
It appears to be B because this quadratic function faces down (-ax^2) and the vertex or highest point of this function is when x=1. Thus, the interval of the domain that the function increases must be from negative infinity to 1, giving the answer B.

what is 234 divided by 2 pls help me
Answer:
the answer 117
Step-by-step explanation:
The 234 divided by 2 is 117.
To calculate 234 divided by 2, we perform the division operation step by step.
Step 1: Divide 234 by 2.
234 ÷ 2 = 117
The result of 234 divided by 2 is 117. When you divide 234 by 2, you are essentially dividing 234 into two equal parts. Each part contains 117. This can be confirmed by performing the calculation:
234 ÷ 2 = 117
Therefore, 234 divided by 2 is 117. Division is the inverse operation of multiplication, and in this case, we find that 234 is evenly divisible by 2, resulting in a whole number quotient of 117.

What is the equation of a line that passes through the point (-7,-8) and parallel to y=5/7x-5.
Answer:
The equation of the line that passes through the point (-7, -8) and parallel to the given line is y = 5/7·x - 3
Step-by-step explanation:
The coordinates of the point the line passes = (-7, -8)
The equation of the line the required line is parallel to is y = 5/7·x - 5
The slope of of the given line is therefore in slope and intercept form with the slope = 5/7 and the y-intercept = -5
The slope of a line parallel to another line are equal, therefore the slope of the required line = The slope of the given line = 5/7
The equation of the required line in point slope form is therefore;
y - (-8) = 5/7 × (x - (-7))
y + 8 = 5/7 × x + 5/7 × 7
y + 8 = 5/7 × x + 5
∴ y = 5/7 × x + 5 - 8 = 5/7 × x - 3
y = 5/7 × x - 3
The equation of the line that passes through the point (-7, -8) and parallel to y = 5/7x - 5 is y = 5/7·x - 3.

Step-by-step explanation:
The another name for the exponent is power, the correct option is D.
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
Given;
A number is written with a base and an exponent
Now,
n exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself and exponent is also called index or power.
