Answer:
$1.48
Step-by-step explanation:
Meal cost: $7.24
Coffee cost: $2.65
Total cost: $9.89
Now we need to find 15% of 9.89.
This is a percentage question, we need to first multiply 9.89 with 15% then divide it by 100%:
9.89 × 15 ÷ 100 = 1.48 approximately.
If it takes 1 4 cup of flour to make 1 6 of a cake, how many cups of flour are needed to make a whole cake?
Answer:
1 1/2 cups of flour.
Step-by-step explanation:
You can work this as a proportion:
1/4 cup → 1/6 of a cake
x cups → 1 cake
Cross-multiply.
(1/4 cup)(1 cake) = (x cups)(1/6 cake)
Solve for x.
x = 6(1/4) = 1 1/2 cups

Graph the line with slope -3 passing through the point (4, - 1)
A graph of the line with slope -3 passing through the point (4, -1) has been plotted in the image attached below.
What is the point-slope form?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.From the information provided above, we have the following slope and data points on the line:
Points = (4, -1).Slope, m = -3At point (4, -1), a linear equation of this line can be calculated in point-slope form as follows:
y - y₁ = m(x - x₁)
y - (-1) = -3(x - 4)
y + 1 = -3x + 12
y = -3x + 12 - 1
y = -3x + 11
Next, we would use an online graphing calculator to plot the above linear equation in slope-intercept form as shown in the graph attached below.

The length of a rectangular garden is 3 m more than its breadth. Find the area of garden, if the perimeter is 54 m.
180
since it's a rectangle it wil have 4 sides hence to find breadth we need to make it a square so all 4 sides will be equal hence 54 minus 3 times 2 and the length of the rectangle is 3 cm longer than the breadth of the rectangle making the perimeter into 48 after the equation 48 divide by 4 equal 12 . so now we know that the breadth of the rectangle is 12 we can add 3 to 12 to find the length of the rectangle and use 12 times 15 to find the area of the rectangle

Mrs. Tenon buys 25 party favors for $5. Find the constant ofproportionality?Mrs. Tenon has spent $5 on 25 party favours.
Equation form of proportional relationships is written as y=kx.
If you substitute $5 for y and $25 for x in the formula for the proportional relationship above, you can find the value of the proportionality constant, or k.
$5=k(25)\sk=$5/25\s=0.2
0.2 is the proportionality constant. Thus, each party favour costs $0.20.
Let's say there are r party favours and the cost is c. c=0.2r
In the equation above, 40 should be substituted for r to get the price of 40 party favours: c=0.2 (60) = 12.00.

An acute triangle is a triangle with all its angles are less than 90 degrees, so an equilateral triangle with all angles of 60 degrees is an acute triangle. An acute triangle doesn't necessarily have to be an equilateral triangle.
