Coffee costs $3.59 per pound. How much would 5.7 pounds of coffee
cost?
Answer:
20.463
Step-by-step explanation:
3.59x5.7
5.7 pounds of coffee would cost $20.463.
What is simplification?When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one method to encourage uniformity in work effort, expense, and duration. It reduces diversity and variation that is detrimental, pointless, or unnecessary.
Given, Coffee costs $3.59 per pound. Since,
1 pound of coffee costs = 3.59$
5.7 pounds of coffee costs = 3.59 * 5.7
5.7 pounds of coffee costs = 20.463
Therefore, $20.463 would be the cost of 5.7 pounds of coffee.

Solve x-34=78 find the value of x
Answer:
112 is the answer
Step-by-step explanation:
to find the value of x, you need to add both the numbers 34 and 78 to find x.
Answer:
x=112
Step-by-step explanation:
x=78+34
(here the 34 passes to the other side, and because it is substracing, you pass it adding)
x=112

at a sale, dresses sold for 22.00 each. This price was 55% of a dress's original price.
Answer:
22.00x55%=12.10. 22-12.10=9.90
Answer:
$40
Step-by-step explanation:
22/55 = dollar per percent
dollar per percent = 0.4
0.4 x 100 will equal to 100% of the original price
0.4 x 100 = 40
to check, 40 x 55% = 22
In the diagram, triangle QRS is congruent to triangle XYZ. Find the measure of angle R.
Answer:
the correct answer is C. 75°
The value of ∠R = 75⁰
What are congruent triangles?The measurements of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of their corresponding sides and angles are equal, two triangles are said to be congruent.
Given ΔQRS ≅ ΔXYZ
for congruency the sides and angle of both the triangles should be equal so for ΔQRS and ΔXYZ ; QR = XY, QS = XZ, and RS = YZ and
∠Q = ∠X, ∠S = ∠Z and ∠R = ∠Y
from figure ∠Q = ∠X = 55⁰, ∠S = ∠Z = 50⁰
sum of angle of triangle is 180⁰,
∠Q + ∠S + ∠R = 180⁰
∠R = 180 - 55 - 50
∠R = 75⁰
Hence ∠R = 75⁰

Given the Vertex (1,0) and the Directrix y = -¼, find the equation of the quadratic
(x - 1)2
(x + 5)2
2(x - 1)2
-x2 - 1
Answer:
y = (x - 1)²
Step-by-step explanation:
A parabola is the locus of a point such that its distance from a fixed point (known as the focus) and a fixed line (known as the directrix) is always constant. The equation of a parabola is a quadratic equation.
The equation of a parabola with a horizontal directrix is given by:
(x - h)² = 4p(y - k).
Where the directrix (y) = k - p, vertex = (h, k)
Given that: Vertex (1,0) and the Directrix y = -¼, Therefore:
vertex = (h, k) = (1, 0). h = 1 and k = 0.
y = k - p
but y = -1/4. Hence:
-1/4 = k - p
p = k + 1/4
p = 0 + 1/4
p = 1/4
Since the equation of the parabola is:
(x - h)² = 4p(y - k).
Substituting:
(x - 1)² = 4(1/4)(y - 0)
(x - 1)² = y
y = (x - 1)²
y = x² - 2x + 1

Answer:
the trip would be 800 miles all together
Step-by-step explanation:
if you divide 240/3 it is 80 which means that 80 miles is 10% of the trip so you can multiply 80 by 10 to see that 800 miles is 100% of the trip.

Which equation has a graph parallel to the graph of 9x + 3y =22?
Answer:
y = -3x + 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = 22 in the form y = mx +c.
9x+3y = 22
3y = -9x +22
y = -3x + 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.

Answer:
The answer to the question provided is 16 units.
.
Step-by-step explanation:
☆Well, we simply use the distance formula, which is:
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]
...
☆All we need to do is plug in!
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]
