Ivan draws PQR on the coordinate plane.
What is the perimeter of PQR? Round to the
nearest unit.
Answers
Answer:
Perimeter of PQR = 37 units (Approx.)
Step-by-step explanation:
Using graph;
Coordinate of P = (-2 , -4)
Coordinate of Q = (16 , -4)
Coordinate of R = (7 , -7)
Find:
Perimeter of PQR
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between PQ = √(-2 - 16)² + (-4 - 4)²
Distance between PQ = 18 unit
Distance between QR = √(16 - 7)² + (-4 + 7)²
Distance between QR = √81 + 9
Distance between QR = 9.48 unit (Approx.)
Distance between RP = √(7 + 2)² + (-7 + 4)²
Distance between RP = √81 + 9
Distance between RP = 9.48 unit (Approx.)
Perimeter of PQR = PQ + QR + RP
Perimeter of PQR = 18 + 9.48 + 9.48
Perimeter of PQR = 36.96
Perimeter of PQR = 37 units (Approx.)

Mr kacanich was baking a chocolate cake. The recipe called for 3/4 cup of unsweetened cocoa powder, but after he started mixing ingredients, he relized he didn't have enough. If mr kacanich borrowed 1/4 cup from the neighbor, how much of his own cocoa powder did he have?
Answers
Answer:
2/4 cup
Step-by-step explanation:
Unsweetened cocoa powder needed = 3/4 cup
Unsweetened cocoa powder borrowed = 1/4 cup
how much of his own cocoa powder did he have?
Let
x = Unsweetened cocoa powder Mr kacanich has
Unsweetened cocoa powder needed = Unsweetened cocoa powder Mr kacanich has + Unsweetened cocoa powder borrowed
3/4 = x + 1/4
Subtract 1/4 from both sides
3/4 - 1/4 = x + 1/4 - 1/4
3/4 - 1/4 = x
x = (3-1)/4
x = 2/4 cup

on March 1, Tessa Obato deposited a check for $9,364.85 in a savings account at state bank. The account pays 4% interest calculated on a daily basis. five days later, on March 6, she withdrew $1,000.00. on March 18, 12 days later, she withdrew $2,000.00. On March 28, 10 days later, she withdrew another $2,000.00. three days later, on March 31, the bank computed interest. how much simple interest did her money earn?
Answers
Her money earned a simple interest of $24.55.
Step-by-step explanation:
Since Tessa deposited $9364.85 and she gets 4% interest on daily basis, then before she withdraws $1000 after 5 days, she must've gotten an interest of:
9364.85 x 4% × (5/365) ≈ 5.13
After withdrawing $1000, she has $8364.85. If this remains in the account for 12days, as we have in the question, then the interest on that will be:
8364.85 x 4% × (12/365) ≈ 11.00
After withdrawing $2000, she has $6364.85. If this remains for 10days, her interest would be:
6364.85 x 4% × (10/365) ≈ 6.98
After withdrawing $2000, she has $4364.85. If this remains for 3days, her interest would be:
4364.85 x 4% × (3/365) ≈ 1.44.
In totality, her interest would be: 5.13 + 11.00 + 6.98 + 1.44 = 24.55.
Hence, her money earned a simple interest of $24.55.

How to find area of a composite figure?The figure above is a composite figure as it has both rectangle and a semi circle.
The area of the figure(sitting room) is as follows:
total area = area of rectangle + area of semi circle
area of rectangle = lw
where
l = lengthw = widthTherefore,
l = 15 ft
w = 14 ft
area of rectangle = 15 × 14 = 210 ft²
Area of semi circle = πr² / 2
Area of semi circle = 3.14 × 7² / 2
Area of semi circle = 3.14 × 49 / 2
Area of semi circle = 153.86 / 2
Area of semi circle = 76.93 ft²
Area of the sitting room and room= 210 + 76.93 = 286.93 ft²

Answer:
x = 10
Step-by-step explanation:
We know that in a parallelogram base angles are supplementary angle (add up to 180°)
Given that;
∠U = 9x + 15
∠V = 6x + 15
we can say that:
∠U + ∠V = 180°
(9x + 15) + (6x + 15) = 180
Combining like terms we get;
15x + 30 = 180°
15x = 180 - 30
15x = 150
x = 150/15
x = 10

Answer:
Step-by-step explanation:
100+2x+40=180(sum of interior angle of a triangle)
140+2x=180
2x=180-140
2x=40
x=40/2
x=20
Answer:
x=20
Step-by-step explanation:
the sum of the angles of a triangle is 180
so it means,
100+40+(2×)=180
140+(2×)=180
2×=180-140
2×=40
divide both sides by 2
x=20
to prove this substitute 20 inside see if the result is 180
40+100+(2×)=180
×=20
40+100+(2 (20))=180
140+40=180
140+40=180
