Answer:

$\frac{1}{4} cups$

Step-by-step explanation:

If the total of the recipe requires 3/4 cups of flour, and Estevan wants to make only 1/3 of the recipe he just needs to do a rule of three in order to calculate how much cups of flour will he need:

$\frac{3}{4} =1\\x=\frac{1}{3}$

So you just create the next equation:

$x=(\frac{3}{4} )(\frac{1}{3}) =\frac{3*1}{3*4}=\frac{3}{12}=\frac{1}{4}$

So Estevan will only need 1/4 cups of flour to make 1/3 of the recipe.

3, 12, 48, 192, 768, . . .

Sav [38]

The answer would be the sequence has a common ratio of 4.
The explanation for this would be:
To get the common ratio for get the simplest form of the two numbers, so 12/3 = 4 and 48/12 = 4So we know that their common ratio is 4.
To check:
3 x 4 = 12
12 x 4 = 48
48 x 4 = 192
192 x 4 = 768

∠QPS is a right angle and m∠QPR = 71°, what is m∠RPS?

natta225 [31]

Answer: <RPS = 161

Step-by-step explanation:

P is the common vertex in all of these angles. From this we know that these have to be adjacent angles (<QPR and <QPS) that equal the whole angle (<RPS)

<QPR+<QPS= <RPS

71+90= 161

(<QPS is a right angle. Right angles are equal to 90 degrees.)

P and Q are two points on the line x - y + 1 = 0 and are at distance 5 from the origin. Find the area of the triangle OPQ.

Alecsey [184]

Answer:

P and Q are two points on the line x-y+1=0 and are at a distant of 5 units from the origin. Find the area of triangle POQ.

Step-by-step explanation:

P and Q are the intersection points of

x-y+1 = 0 and the circle x^2 + y^2 = 25

sub y = x+1 into the circle

x^2 + (x+1)^2 = 25

x^2 + x^2 + 2x + 1 - 25 = 0

x^2 + x - 12 = 0

(x+4)(x-3) = 0

x = 3 or x = -4

y = 4 or y = -3

so P(3,4) and Q(-4,3) are our two points

Height of triangle.

h = |0 - 0 + 1|/√2 = 1/√2

PQ = √( (-7)^2 + 1^2) = √50 = 5√2

area POQ = (1/2)(1/√2)(5√2) = 5/2 square units

hope this helped
