Answer:
B = 12.8 cm (to 1.d.p)
D = 24.1 cm (to 1.d.p)
Step-by-step explanation:
Using Pythagoras Theorem:
B: 4^2 + 3.5^2 = 28.25
square root 28.25 = 5.3 (to 1 decimal place) so this is the length of the missing side.
To find perimeter add sides a, b and c so...
perimeter of triangle B = 12.8 cm (to 1 decimal place)
D: 10^2 - 6.5^2 = 57.75
square root 57.75 = 7.6 (to 1 decimal place) so this is the length of the missing side.
To find perimeter add sides a, b and c so...
perimeter of triangle D = 24.1 cm (to 1 decimal place)
^2 indicates squared

Quadrilateral abcd is rotated 90 degrees clockwise about the origin. What are the coordinates of A'B'C'D?
Answer:
your answer is A
Step-by-step explanation:
have a nice day!! ^_^
The coordinate of A` is (5,5) , the coordinate of B` is (5,1), the coordinate of C` is (2,1) and the coordinate D` is (1,5).
What is the coordinate of a point?A pair of number that describes the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinate of a point. Coordinates are usually denoted by (x, y).
From the figure we can see that A` is 5 unites right of vertical line and 5 unit upward the horizontal line. So, the coordinate of A` is (5,5).
Similarly, B` is 5 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of B` is (5,1).
C` is 2 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of C` is (2,1).
And, D` is 1 unit right of vertical line and 5 unit upward of horizontal line. So, the coordinate of D` is (1,5).
Hence the coordinates of A`B`C`D` is (5,5), (5,1), (2,1) and (1,5) respectively.

The four small circles are identical. The total area of the small circles is 36π square inches. What is the area of the larger circle?
Answer:
Check pdf
Step-by-step explanation:
The radius of the larger circle is 12 inches. Then the area of the larger circle will be 144π square inches.
What is the area of the circle?Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The four small circles are identical. The total area of the small circles is 36π square inches. Then the radius of each small circle is given as,
36π = 4 × (πr²)
r² = 9
r = 3 inches
Then the radius of the larger circle is calculated as,
R = 4r
R = 4 × 3
R = 12
Then the area of the larger circle will be given as,
A = π × (12)²
A = 144π square inches
The radius of the larger circle is 12 inches. Then the area of the larger circle will be 144π square inches.

8) Jalyn purchased three different sized drinks. The large was twice as much
as the medium drink. The MEGA drink was $10 more than the large. Jalyn
spent a total of $45 on drinks! Write and solve an equation to determine the
cost of the medium drink.
Answer:MARK ME AS BRAINLIEST
MEGA Drink = $10+2x
LARGE Drink = 2x
MEDIUM Drink = x
hence, we conclude that
($10+2x) + 2x + x = $45
$10+2x + 2x + x =$ 45
5x + $10 = $45
5x = $45-$10
5x = $35
x = 35÷5
x = 7
MEGA DRINK = (10+2X)
10+2×7
10+14

LARGE DRINK = 2X
2×7 = 14
MEDIUM DRINK = X

Step-by-step explanation: You can convert 3 and 1/3 to 10/3. Now you have (10/3) / (2/3). Dividing by a fraction is the same as multiplying by the reciprocal of the fraction, so you can do (10/3) * (3/2) to get 5
Answer:

Copy the shape and fill in the missing angle. Sow the work. Thanks.
Answer:
x=12
Step-by-step explanation:
Hello There!
So first things first, the angle labeled 4x+17 and the blank interior angle are vertical angles meaning that they are congruent
So now we can solve for x
Remember all of the angles in a triangle add up to equal 180 so
180 = x + 23 + 80 + 4x + 17
step 1 combine like terms
4x+x=5x
23+17+80=120
now we have
180=120+5x
step 2 subtract 120 from each side
180-120=60
now we have
60=5x
step 3 divide each side by 5
60/5=12
we're left with x=12

April, x, slept 9 hours; Evelyn slept 2/3
less than that.
Evelyn slept _______________ hours. Write the equation as both a decimal and fraction.
live to be 80 years old and sleep 8 hours a day, How many years have I slept
Solution
A day has 24 hours
24 = 8 + 8 + 8
So you spent 1/3 of your time sleeping.
You can get the same answer if you do 8/24
8/24 = (8 ÷ 8) / ( 24 ÷ 8) = 1/3
All you need to do now is to find 1/3 of 80
1/3 of 80 = 1/3 × 80 = 80/3
80 / 3 = (78 + 2) / 3 = 78 / 3 + 2 / 3 = 26 + 2/3
So that is 26 years + ( 2/3 of a year)
What is 2 / 3 of a year?
Since 2 /3 of a year is a fraction of a year, the answer for 2 / 3 of a year will be in months.
1 year = 12 months.
Just find out what 2/3 of 12 is
2/3 of 12 is 2/3 times 12
2/3 times 12 = (2 times 12) / 3 = 24 / 3 = 8 months
Putting everything together, you slept for 26 years and 8 months during your lifetime.
Hope it helped!

3. A kite is aloft at the end of a 1500 foot string. The string make an angle of 43° with the
ground. How far above the ground is the kite?
Do not calculate! Please provide your answer in calculator ready form. For example: h -
237cos(3129)
Answer:
[tex]h= 1500\,*\,sin(43^o)[/tex]
Step-by-step explanation:
Notice that there is a right angle triangle formed with sides as follows:
hypotenuse is the actual 1500 ft string. The acute angle 43 degrees is opposite to the segment that represents the height of the kite from the ground. Therefore, the trigonometric ratio that we can use to find that opposite side to the given angle, is the sine function as shown below:
[tex]sin(43^o) = \frac{opposite}{hypotenuse} \\sin(43^o) = \frac{opposite}{1500}\\opposite = 1500\,*\,sin(43^o)\\h= 1500\,*\,sin(43^o)[/tex]
John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?
sample response: The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.
Answer:
The transformation rule should be applied to the pre-image. The application of the rule results in the point (8, 12). The transformation rule was applied to the wrong point.
