Answer:
27°C
Step-by-step explanation:
Average temperature on 4 days
[tex] = \frac{total \: temperatures \: for \: 4 \: days}{4} [/tex]
Total temperatures for 4 days
= 4(22)
= 88
If the average temperature throughout 5 days is 23°,
total temperature for 5 days
= 5(23)
= 115
Temperature on the 5th day
= total temperatures for 5 days -total temperature for 4 days
= 115 -88
= 27°C

A. 120 square units
9
10
B. 174 square units
16
C. 66 square units
12
D. 84 square units
Answer:
D
Step-by-step explanation:
12-9 = 3 square unit
10 x 3 = 30 square unit
9×6 = 54 square unit
54+30 = 84 square units
and thats the answer
The area of the polygon is 84 square units, option D is correct.
What is Area of Rectangle?The area of Rectangle is length times of width.
The given polygon has two rectangles.
Area of rectangle with length 9 and width is 6 units
Area of rectangle 1 =9×6
=54 square inches
Now Area of rectangle with length 10 and width is 3 units
Area of rectangle 2 =10×3
=30 square inches
Total area = 54+30
=84 square units
Hence, the area of the polygon is 84 square units, option D is correct.

PLEASE HELP !!!! ILL GIVE BRAINLIEST !!!
Answer:
Hi it's down below! Hope it helps
Step-by-step explanation:
1) The angles are Supplementary
This is because both angles form 180°. The angle below angle "7x+9" is the same as 5x+3. The angle above angle"5x+3" is the same as 7x+9.
2) They are both supplementary
They form 180°
3)180° = 12x+12°
4) Solving that:
180° - 12° = 12x
168° = 12x
x = 168°/12
x = 14°

Answer:
b = 9cm is the answer.
Step-by-step explanation:
a = 12cm
b = ?
c = 15cm
By using the Pythagoras theorem,
a² + b² = c²
12² + b² = 15²
144 + b² = 225
b² = 225 - 144
b² = 81
b = 9cm.
∴ b = 9cm is the length of the missing leg.

Which of the following would increase if the professional football players were removed from the data set?
Answer:
the standard deviation of the residuals
Step-by-step explanation:
The removal of the professional football players will cause the correlation, and consequently r2 to become closer to 0 due to the fact that the high school athletes tend to show no association between the number of energy drinks consumed and the number of pull ups that can be done. The slope of the regression line will also be nearly 0 without the professional football players. The standard deviation of the residuals, however, will increase without the presence of the professional football players because the remaining scatter about the new regression line will be greater due to the loss of the 4 professional football players which all had small residuals.
The option that will increase if the football players were removed from the data set is the standard deviation of the residuals
What is standard deviation?It should be noted that standard deviation simply means the difference between the observed data and the predicted values.
In this case, the standard deviation of the residual will increase if the football players were removed from the data set as the removal of the professional football players will cause the correlation.

For instance, the numbers 1, 28, and 5 are all imaginary numbers.Complex numbers cannot be plotted on the actual number line because they contain imaginary numbers. On the complex number plane, which has a y axis (for the imaginary number) and an x axis (for the real number), they can, however, be measured starting from zero (for the imaginary number).In all these options , they are presenting real complex number .Real numbers can be positive or negative, and include the number zero. that is why we select option D .

Area of base = 20.25π
Step-by-step explanation:
Given:
Diameter of cylinder = 9 inch
Height of cylinder = 22 inch
Find:
Radius of cylinder
Circumference of Base
Area of base
Computation:
Radius of cylinder = Diameter of cylinder / 2
Radius of cylinder = 9 / 2
Radius of cylinder = 4.5 inch
Circumference of Base = 2πr
Circumference of Base = 2π(4.5)
Circumference of Base = 9π inch
Area of base = πr²
Area of base = π(4.5)²
Area of base = 20.25π

Answer:
b) rotational symmetry: multiples of 120°
Step-by-step explanation:
The figure does not have a line of symmetry, or a point of symmetry. However, rotating it 1/3 turn (120°) will make it look like itself. Hence, it has rotational symmetry of degree 3. A rotation of any multiple of 120° will map the figure to itself.
