Step-by-step explanation:
if ZA and ZB are supplementary angles. if mZA = (3x-23) and mZB= (2x-12) then find the measure of ZB
Answer:
mZB= 74
Step-by-step explanation:
ZB+ZA=180
3X-23+2X-12=180
5X-35=180
5X=180+35
5X=215 (then divide both sides by 5 to x be left alone.)
X=43....so ZB=2(43)-12

(3, 15)
(-4, 36)
(3, 15) and (4, 12)
(-3, 33) and (-4,36)
Answer:
(3, 15) and (4, 12)
Step-by-step explanation:
x2 - 7x+12 = 0 factors to (x - 4)(x - 3) = 0, and so x: {3, 4}.
Since y= -3x + 24, y = 15 when x = 3 and y = 12 when x = 4. The solutions are thus (3, 15) and (4, 12). This is the third answer choice.
Answer:
see the explanation
Step-by-step explanation:
Y = –x2 + 4x + 12
y = –3x + 24
so
–x2 + 4x + 12 = –3x + 24
x^2 -7x + 12 = 0
(x - 4)(x - 3) = 0
x - 4 =0; x =4
x - 3 = 0; x= 3
y = –3x + 24 = -3(3) + 24 = -9+24 = 15 (when x = 3)
y = –3x + 24 = -3(4) + 24 = -12+24 = 12 (when x = 4)
answer
(3, 15) and (4, 12)

Each gallon of paint covers 200 square feet. I have to paint one side of a wall that is 12 meters tall and 80 meters long. If a foot is approximately 0.3048 meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall? Plz answer immediately, the answer is not 9 gallons.
Answer:
51 gal
Step-by-step explanation:
Find the area of the wall you need to paint:
12 m * 80 m = 960 m^2
Use conversion rate to convert square meters to square feet (first, make the conversion rate into square meters instead of regular meters):
1 ft / 0.3048 m -> 1^2 ft / 0.3048^2 m^2
960 m^2 * (1 ft^2 / 0.3048^2 m^2)
Square meters cancel out, we are left with square feet:
960 * (1 ft^2 / 0.3048^2) = 10333.354 ft^2
Now, find how many gallons of paint by dividing by 200 square feet:
10333.354 ft^2 / 200 =~ 51.66 gal
Round up to the nearest whole number:
51.66 =~ 51 gal
The smallest whole number of gallons require to paint the wall is 52 gallons.
1 gallon of paint = 200 ft²
I foot = 0.3048 metres
Dimension of wall :
12 metre by 80 metre
Converting the dimension to feet :
12 meter / 0.3084 = 39.370078 feets
80 meter / 0.3084 = 262.46719 feets
Hence, the area of the wall in feet²:
Area = Length × width
Area of wall = 262.46719 × 39.370078 = 10333.3537427408 ft²
Let number of falloms required = x
Since,
1 gallon = 200 ft²
x gallons = 10093.516 ft²
Cross multiply :
200x = 10093.516
x = 10333.35374274082 / 200
x = 51.6667687137041 gallons
x = 52 gallons
Hence, the smallest number of gallons required to paint the wall is 52 gallons of paint

1. Знайдіть периметр паралелограма, сторони якого дорівнюють 5 см і 11 см.
2. Один з кутів ромба дорівнює 53°. Знайдіть інші кути ромба.

4. Знайдіть сторони прямокутника, якщо вони відносяться як
2 : 3, а площа прямокутника дорівнює 96 см².
Answer:
1) Perimeter of the parallelogram = 32 cm
2) The angles of the rhombus include 53°, 53°, 127° and 127°.
3) The length of the median drawn to the smaller of the legs = 13 cm
4) The sides of the rectangle are 8 cm and 12 cm
1) Периметр параллелограмма = 32 см
2) Углы ромба включают 53 °, 53 °, 127 ° и 127 °.
3) Длина медианы обращена к меньшей из ног = 13 см.
4) стороны прямоугольника 8 см и 12 см
Step-by-step explanation:
English Translation
1) Find the perimeter of the parallelogram, the sides of which are 5 cm and 11 cm.
2) One of the angles of the rhombus is 53 °. Find the other angles of the rhombus.
3) The legs of a right triangle are 12 cm and 10 cm. Find the length of the median drawn to the smaller of the legs.
4) Find the sides of the rectangle if they are related as 2: 3, and the area of the rectangle is 96 cm².
Solution
1) Find the perimeter of the parallelogram, the sides of which are 5 cm and 11 cm.
A parallelogram has each of its opposite sides to be equal in length.
Perimeter of a parallelogram = 2(l + b)
l = 11 cm
B = 5 cm
Perimeter = 2(11 + 5) = 32 cm
2) One of the angles of the rhombus is 53 °. Find the other angles of the rhombus.
A rhombus is a quadilateral with the sum of its internal angles equal to 360°. Also, opposite angles of a rhombus are equal in magnitude.
Let the unknown other complementary angle be x.
53° + 53° + x + x = 360°
2x + 106° = 360°
2x = 360° - 106° = 254°
x = (254°/2) = 127°
The angles of the rhombus include 53°, 53°, 127° and 127°.
3) The legs of a right triangle are 12 cm and 10 cm. Find the length of the median drawn to the smaller of the legs.
The median is the line drawn from the vertex opposite a triangle's side to the midpoint of that side.
The median described is drawn in the attached image to this question.
From the image, the small triangle is a right angled triangle, hence, the length of the median is given by Pythagoras theorem.
(Median)² = 12² + 5² = 169
median = 13 cm
4) Find the sides of the rectangle if they are related as 2: 3, and the area of the rectangle is 96 cm².
Let the breadth and length of the rectangle be x and y respectively.
x:y = 2:3
(x/y) =(2/3)
x = (2y/3)
Area of a rectangle = length × breadth = x × y = xy = 96
x = (2y/3)
(2y/3) × y = 96
y² = (96×3/2) = 144
y = 12 cm
x = (2y/3) = (2×12/3) = 8 cm

All the children of a class were asked to choose between the cartoon shows 'Shin Chan' and 'Tom and Jerry'.The ratio of children who selected the cartoon 'Shin Chan' to those who selected the cartoon 'Tom and Jerry', was 3:1.
If 45 kids selected 'Shin Chan', how many students are there in the class totally?
Answer:
There were 60 kids in class.
Step-by-step explanation:
Since the kids had two choices and the ratio between them was for every 3 children that selected "Shin Chan" only 1 selected "Tom and Jerry", then in order to calculate the number of children in the class if 45 kids selected "Shin Chan", we first need to calculate the number of children that selected the other option. To do that we divide the number by 3. We have:
children(Tom and Jerry) = children(Shin Chan)/3
children(Tom and Jerry) = 45/3 = 15
Therefore the number of children in the class is:
children(class) = children(Tom and Jerry) + children(Shin Chan)
children(class) = 15 + 45 = 60
There were 60 kids in class.

Answer:
PEMDAS
Step-by-step explanation:
P=Parenthesis
E=Exponent
M=Multiply
D=Division

S=Subtract
The first step you should perform is the exponent 3 of base 8.
What is BODMAS Rule?BODMAS rule is the rule used when solving expressions involving more than one operations.
It is the abbreviation of Brackets, Order, Division, Multiplication, Addition, Subtraction, which is the order of the operations to be done.
The given expression is 8³ - 10 × 5 - 4.
We know the rule of BODMAS.
since the given expression includes more than one operations, we have to follow the rule of BODMAS.
There are no brackets in the expression.
There is a power of 3 for the base 8.
We should perform that in the first step.
8³ - 10 × 5 - 4 = 512 - 10 × 5 - 4
Next we do the operation of multiplication.
512 - 10 × 5 - 4 = 512 - 50 - 4
There is subtraction.
512 - 50 - 4 = 566
Hence the operation of the power is done first.

B) David and Andrew are traveling to a Mathematics conference. David travels 110 miles in the same time that Andrew travels 140 miles. Andrew travels 15 miles per hour faster than David. Find the average rate of each person.
Answer:
David's average speed is 55 mph and Andrew's average speed is 70 mph
Step-by-step explanation:
Let David's speed be s.
Average speed is given as:
speed = distance / time
They both spent the same time, t.
David's speed is:
s = 110 / t
=> t = 110 / s
Andrew travels 15 mph faster than David.
Andrew's speed is:
(15 + s) = 140 / t
=> t = 140 / (15 + s)
Therefore, since they spent the same time:
110 / s = 140 / (15 + s)
Cross multiply:
110(15 + s) = 140s
1650 + 110s = 140s
1650 = 140s - 110s
30s = 1650
s = 1650 / 30
s = 55 mph
Andrew's speed is:
15 + 55 = 70 mph
Therefore, David's average speed is 55 mph and Andrew's average speed is 70 mph.
