Sally would like to have an average of 92 in her math class. She has completed four assignments with the following grades: 88, 97, 91, 86. What is the lowest grade Sally will need to make on the last assignment to meet her goal?
Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5
This would get of / 5 so you don't need to divide by 5
362 + x = 460
Subtract 362 from each side
x = 98

Which graph can be used to find the solution to the system of equations below?
2x + y = -4
-3y = 2x + 12
Answer:
x = 0, y = -4
Now plug it in:
y = mx + b
-4 = b
So the y intercept is -4
You can also graph the equation.

A. A linear function because the students are decreasing by 5 each year.
B. An exponential function because the students are decreasing by 5 each year.
C. An exponential function because there is a 5% decay.
D. A linear function because there is a 5% decay.
find the area of the figure
Answer:
area of shaded region={6+7)×8-1/2×7×8=76 ft²
Answer:
The area of the purple is 76 feet.
Step-by-step explanation:
8 * 6 = 48
the full rectangle is 48ft in area
7 * 8 = 56
56 / 2 = 28
48 + 28 = 76ft

HELP NEEDED ASAP PLZZZZZZ
Michele is making a kite based on the pattern below. About how much binding does Michele need to cover the edges of the kite?
Answer:
about 52.1 in.
Step-by-step explanation:
PM=PE=5 inches, PR=4 inches, and OP=19 inches.
Since the figure is a kite, the diagonals ME and OR are perpendicular and form right triangles with their hypotenuses forming the sides of the kite, OM, MR, RE, and EO.
The figure shows the same kite O M R E as in the beginning of the task. Diagonal O R is perpendicular to diagonal M E.
Use the Pythagorean Theorem to calculate the length of OM.
OM=OP2+PM2−−−−−−−−−−√
Substitute 19 for OP and 5 for PM.
OM=192+52−−−−−−−√
=361+25−−−−−−−√
=386−−−√
Therefore, OM=386−−−√ in.
By the definition of a kite, OM≅EO. So, EO is also equal to 386−−−√ inches.
Use the Pythagorean Theorem to calculate the length of MR.
MR=PM2+PR2−−−−−−−−−−√
Substitute 5 for PM and 4 for PR.
MR=52+42−−−−−−√
=25+16−−−−−−√
=41−−√
Therefore, MR=41−−√ in.
By the definition of a kite, MR≅RE. So, RE is also equal to 41−−√ inches.
The figure shows the same kite O M R E as in the beginning of the task. Sides O M and E O are square root of 386 inches long. Sides M R and R E are square root of 41 inches long.
The perimeter of the kite is the sum of the four sides.
Perimeter of OMRE=OM+MR+RE+EO
=386−−−√+41−−√+41−−√+386−−−√
=2386−−−√+241−−√
Use a calculator to approximate.
Perimeter of OMRE≈52.1 in.
So, the perimeter of OMRE is about 52.1 inches.
Therefore, about 52.1 inches of binding are needed to cover the edges of the kite.
