2.25 cups of flour he use per patch.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Pablo uses 13.5 cups of flour to make 6 batches of muffins.

For 1 patch amount of flour used

= 13.5 /6

= 2.25 cups

Hence, 2.25 cups of flour he use per patch.

(4x+1)(16x^2-4x+1)

Answer:

2x - y - 8 = 0

Step-by-step explanation:

x1 = 2

y1 = -4

m = 2

using the formula,

y-y1 = m(x-x1)

y+4 = 2(x-2)

y+4 = 2x - 4

y-2x+4+4 = 0

y-2x+8 = 0 (×-1)

2x - y - 8 = 0

Therefore the equation of the line is;

2x-y-8 = 0

Answer:

y = 35- 15x

Step-by-step explanation:

To solve for y, first isolate the term containing y.

1/5y = 7 - 3x

Multiply both sides by 5 to cancel out the fraction.

5(1/5y) = 5(7 - 3x)

This will result in:

y = 35- 15x

Do not forget to distribute the 5 when multiplying.

The equation is now solved for y.

Answer:

if you’re looking for a equation it could be “ 24c + 15 = 687 “Step-by-step explanation:

Beginner courses cost $18 while advanced courses cost $24.

Let b represent the cost of the beginner classes and a represent the cost of advanced classes.

The beginner costs 6 more than half the cost of the advanced class. Hence:

b = a/2 + 6  

2b = a + 12

2b - a = 12    (1)

Last week they taught 7 beginner classes and 11 advanced classes and earned $390, Hence:

7b + 11a = 390   (2)

Solving equations 1 and 2 simultaneously gives: b =  18, a = 24

Beginner courses cost $18 while advanced courses cost $24.

Answer:

umm i think its 9

Step-by-step explanation:

B i think or D can someone help

Answer:

C and A

Step-by-step explanation:

Remember what slope means: [tex]\frac{rise}{run}[/tex].

9. The first slope is 2, or [tex]\frac{2}{1}[/tex]. This means it is moving up 2 and over 1. The second option is the reciprocal, [tex]\frac{1}{2}[/tex]. The second slope moves up 1 and over 2. The first slope is going higher than the second at the same distance. But then we are given the third slope. I'm going to assume here that it does not matter whether the slope is negative or positive, you are only considering steepness. If our first slope moved up 2 and over 1, this slope moves down 4 and over 1, meaning it is covering more area over the same distance. So the steepest slope is option C.

10. Right off the bat we can get rid of option C. The slope is zero, meaning a flat line with no steepness. Next, we need to figure out if A or B is steeper.

First, we can turn them into mixed numbers in order to better be able to tell which is greater.

[tex]\frac{5}{3}=1\frac{2}{3}[/tex]

[tex]\frac{-3}{2}=-1\frac{1}{2}[/tex]

Because we don't care whether the line is ascending or descending, we will compare the absolute value of the slopes.

[tex]1\frac{2}{3} >1\frac{1}{2}[/tex]

So we can see that slope A, [tex]\frac{5}{3}[/tex] is steeper than slope B.

I hope this helps!

Answer:

Radians are used to measure angles. ... A 360 degree angle is the same as a 2pi radian angle. Radians start being used in geometry and trig as you start using the unit circle. I think marking them in the unit circle is a good way to visualize how they work, and how they can be a good unit to work with in that context.

Answer:

w = 4cm L = 5 cm

Step-by-step explanation:

w = w

L = 2w - 3

P = 18 = 2L + 2w

18 = 2(2w-3) + 2w

18 = 4w -6 + 2w

18 + 6 = 6w

24 = 6w

w = 4 cm

L = 2w - 3

L = 2(4) -3

L = 8 - 3

L = 5 cm

x = 106

Answer:

106

Step-by-step explanation:

You need to remember that a triangle will always add up to 180 degrees.

If we add angle degree 42 and 32, we know that the angles combined add up to 74.

180-74=106

So the last angle has 106 degrees left to use

Answer:

60% of 600 = (60/100)x600

= 360

While Daniel only has 320

Hence Josh has saved more

Josh saved $360 and $40 more saved by Josh.

Given that, Josh and Daniel each want to save $600 to attend a sports camp.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here, Daniel has saved $320.

Josh has saved 60% of the amount.

So, 60% of 600

= 60/100 × 600

= 0.6 × 600

= 360

Difference in Josh and Daniel saved money = 360-320

= 40

Therefore, Josh saved $360 and $40 more saved by Josh.

Answer:

5 11/12 cups of melon

Step-by-step explanation:

The cups of melon he puts in the fruit salad is:

Number of cups of orange melon + Number of cups of green melon

= 3 1/4 cups + 2 2/3 cups

3 + 2 + (1/4 + 2/3)

The Least common denominator is 12

5 + (3 × 1 +4 × 2/12)

5 + (3 +8/12)

5 11/12 cups

Therefore, Jason put in 5 11/12 cups of melon in the fruit salad.
