A bakery has 36 glazed donuts on display. This is 80% of the total number of donuts. What is the total number of donuts in the bakery?
Answer:
it is 64.8, but you have to round to the nearest number, so i would say 65 :)
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
% means out of 100, so 80% is 80/100
Let's divide 100/80 to find a scale we can use to multiply 36, 100/80 =
36 times 1.25 = 45
There's 45 donuts
Double check:
45(80/100) = 36, we're right

Step-by-step explanation:
Solve the system by elimination
2x – y=1
x + 3y – 4= 0
The value of x and y for the given equation by elimination method are 1 and 1 respectively.
Elimination method for solving the system of equations;The elimination method is the process of eliminating on of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the given question
We have two equations
[tex]2x -y =1...(1)[/tex]
[tex]x+3y-4=0...(2)[/tex]
Multiply equation (1) both the sides by 3
[tex]6x - 3y =3...(3)[/tex]
Adding equation (2) and (3)
[tex]6x+-3y+x+3y -4 =3\\7x =7\\x =1[/tex]
Substitute
x =1, in either 2x -y =1 or x + 3y -4 =0
2(1) - y =1
⇒ -y = 1 -2
⇒ -y = -1
⇒ y =1
Hence, the value of x and y is 1 and 1 respectively.

Swim floats are on sale at sam’s shop. They are marked 30% off of the original price of 18.00. How much will the float cost
Answer:
the cost is now $5.40
Step-by-step explanation:
if 18.00 is 100%, and we need to find the new price we need to make 30% into a decimal. which is 0.3. then we multiply 0.3 times 18.00, and that equals 5.4, but since we are dealing with money the answer would be $5.40.
we multiply if we are trying to find the new amount and we divide to find the old amount.

What can you conclude from the diagram
Answer:
You can conclude from the diagram that m∠P is less than m∠N ⇒ A
Step-by-step explanation:
In any triangle, you can arrange the lengths of the sides according to the measure of the opposite anglesIn any triangle, you can arrange the measure of the angles according to the lengths of the opposite sidesExample:
In ΔABC, if the arrangement of the sides is AB < BC < CA, then the arrangement of the measures of the angles is m∠C < m∠A < m∠B
Let us use this fact to solve the question
→ In ΔKNP
∵ KP = 8 units
∵ KN = 6 units
∵ 6 < 8
∴ KN < KP
∵ ∠P is opposite to the side KN
∵ ∠N is opposite to the side KP
∵ KN < KP
→ By using the fact above
∴ m∠P < m∠N
∴ m∠P is less than m∠N
∴ You can conclude from the diagram that m∠P is less than m∠N
write the equation of the line thay passes through the point (2,-1) and has a slope of -3
Answer:
Y = -3x -1
Step-by-step explanation:
Y = mx + b
Y is the y intercept (x,y) always graph on y axis
M is the slope
Answer:
Step-by-step explanation:
use the point slope equation.
y-y1 = m(x-x1)
the point is (x1, y1) = (2, -1)
the slope is m = -3
y+1 = -3( x-2)
y = -3x +6-1
y = -3x +5

A home improvement store buys snow shovels from a supplier for $8.50. The day before a snowstorm the store manager marks up the price by 180% to calculate the retail or selling price. What is the retail price of the snow shovel?
Answer:
The retail price is $15.30
Step-by-step explanation:
To solve this, turn the percentage into a decimal. Do this by dividing it by 100.
180 ÷ 100 = 1.8
Then, multiply the supplier price by the decimal
8.5 × 1.8 = $15.30

Answer:
A normal is an object such as a line or vector that is perpendicular to a given object. ... If normal is 90 degree to the surface, that means normal is used in 3D. Perpendicular in that case is more in 2D referring two same entities (line-line) with 90 degree angle between them.
Which of the equations are true identities? \begin{aligned} \text{A. }&(y+6)(y-7)+42=y^2-y \\\\ \text{B. }&(x+3)(x-8)=x^2-5x \end{aligned} A. B. (y+6)(y−7)+42=y 2 −y (x+3)(x−8)=x 2 −5x
Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.
