Answer:
40 is the total amount of cookies
32 is the amount left
Step-by-step explanation:
If 20% of cookies equal to 8 then to find how many are there in total we multiply 8 with 100 then divide it with 20
8 × 100 ÷ 20 = 40

Answer:A
Step-by-step explanation:
Need help with this question. I will give Brainliest!
Answer:
See below
Step-by-step explanation:
a) The vertex is (0,2) so the standard form equation is (x-0)^2=4p(y-2). Since p=1/(4a) and a=1/8, then p=1/(4(1/8))=1/(1/2)=2. This makes the equation now x^2=8(y-2). Given the focus point for a vertical parabola is (h,k+p) then the focus point is (0,2+2) which is (0,4)
b) They are both 4 units away
c) I can't solve
d) I can't solve

What is the cos x =1.7%2 and x is acute angle
Given :
cos x = 1.7/2 .
Also, x is an acute angle.
To Find :
The value of angle x.
Solution :
cos x = 1.7/2
Applying cos inverse both the sides, we get :
[tex]cos ^{-1} (cos\ x ) = cos^{-1} \dfrac{1.7}{2}\\\\x = cos^{-1} \dfrac{1.7}{2}[/tex]
Calculating the value of [tex]cos ^{-1} \dfrac{1.7}{2}[/tex] from calculator, we get :
x = 31.79°
Therefore, the acute angle x is 31.79°.

A woman bought 210 oranges for GH¢65.00. she sold all of them at 3 for ¢20.00. how much profit did she make?
Answer:
She made a profit of 1,335 cedis
Step-by-step explanation:
Here, we want to calculate the profit made
Profit is selling price - cost price
Her cost price is 65 credits
For her selling price;
she sells 3 for 20 cedis
So the price she sold 210 will be;
(210 * 20)/3 = 1,400 cedis
So the profit made is;
1,400-65 = 1,335 cedis
HELP:
A table contains the ordered pairs (3, 42.25) and (5, 50.75). If the relationship in the table is linear, explain how to find the initial value.
I need the answer quick, and thank you!!!
Answer:
First you can find the rate of change to be 4.25. Then you can subtract 4.25 repeatedly until you get to an output with an input of zero. The initial value is the output when the input is zero. The initial value after subtracting 4.25 three times is 29.50. Because the inputs go by 2, the rate of change is half the difference of the outputs, or 4.25. Subtract 4.25 repeatedly 3 times to get to an output with an input of 0. Calculate 42.25 – (3 x 4.25). The initial value is 29.50.
Hope this Helps!
Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.
Answer:
m = n = 20
Step-by-step explanation:
Here, we want to find the missing side lengths
For a 45-45 triangle, the lengths have a side ratio of;
1:1: √2
We should understand that the triangle is isosceles ( opposite and adjacent are equal)
So n = m
So what we just need to do here is divide 20 √2 by √2
Mathematically, that would be;
20 √2/√2 = 20

Answer:
x=23.5
Step-by-step explanation:
90=25-x/2+18
combine like terms
90=43-x/2
subtract 43 from both sides
47= -×/2
47/2= 23.5
x=23.5
or
90-25= 65
65-18=47
47/2=23.5
A system of linear equations includes the line that is created by the equation y = 0.5 x minus 1 and the line through the points (3, 1) and (–5, –7), shown below.
Answer:
(2, 0)
Step-by-step explanation:
First we need to get the equation of the line passing through the points (3, 1) and (–5, –7)
Equation of a line is y = mx+c
m is the slope
m = y2-y1/x2-x1
m = -7-1/-5-3
m = -8/-8
m = 1
Substitute m = 1 and the point (3, 1) into the equation y = mx+c and get c;
1 = 1(3) + c
1 = 3 + c
c = 1-3
c = -2
The required equation is y = x - 2
We are to look for the coordinate point (x,y) for which both lines intersects, then both equations will be equal as shown;
0.5x - 1 = x - 2
0.5x - x = -2+1
-0.5x = -1
x = -1/-0.5
x = 2
Substitute x = 2 into y = x - 2
y = 2-2
y = 0
Hence the the coordinate point is (2, 0)
Answer: (2,0)
Step-by-step explanation: Because I just took the Unit Test and got 100% on it.

An online bookstore sells all paperback books for "x" dollars each. Aidan bought 7 paperback books and spent $3.95 on shipping. Nina bought 11 paperback books and spent $5.25 on shipping. What expression represents the total amount that Aidan and Nina spent?
Answer:
Aidan: 7x + 3.95 = y
Nina: 11x + 5.25 = y
A taxi company charges an initial fee of $1.95, plus $1.60 per mile driven. Shelly has $22.00 to spend on a taxi ride. Which inequality represents the number of miles, m, that Shelly can ride in a taxi
Answer:
Equation
1.95+1.6m ≤ 22
If solved
m ≤ 12.53
Step-by-step explanation:
SO we know the initial fee is 1.95
and for every mile driven, its $1.6
And we know that Shelly can spend less then or exactly the price of 22.
We know that m is miles driven
So we can make an equation
1.95+1.6m ≤ 22
1.95 can’t change since initial fee
1.6*m becuase its 1.6 for every mile driven and since “m” miles were driven, we multiply that by 1.6
Now it can’t go over 22 but it could be less than 22.
So this equation makes sense
If we solve it, it would be about m ≤ 12.53 miles
