Which is the perimeter of the shape? (1 point)
Answer:
22
Step-by-step explanation:
4 x 2 + 7 x 2 = 22
Answer: 22
Step-by-step explanation:
to find perimeter you have to add up all the sides around a shape.
7 + 7 + 4 + 4 = 22
OR
7+7= 14
4 + 4 = 8
14 + 8 = 22
A school has an equal amount of boys and girls. You use a coin to simulate the first three students to arrive at school each day, where "heads" represents a boy and "tails" represents a girl. The table below shows a sample of 20 coin tosses
Find the the experimental probability that the first three students that arrive at school are boys.
No links please! I will reward brainliest for the correct answer. Thanks.
Answer:3/20
Step-by-step explanation:
Heads=Boy
Tails=Girl
If the first 3 students are boys, all 3 coins must be heads.
Because in 3 of these experiments, the coins all land on heads, and there are 20 experiments completed, 3 out of the 20 experiments are 3 boys; 3/20.
Miss David's birthday is in April, and she is going to have a party. She is looking to buy a bag of decorations. Each bag has two different types of decorations: balloons and streamers. The first bag has 11 balloons and 6 streamers. The second bag has 15 balloons and 4 streamers. The last bag has 6 balloons and 12 streamers. Bag 1 costs $91, bag 2 costs $99, and bag 3 costs $102. How much does each type of decoration cost?
Answer:
b = $5
s = $6
Step-by-step explanation:
this can be solved using simultaneous equation
s = streamers
b = balloons
either of the 3 equations can be used to determine the price of the items
11b + 6s = 91 equation 1
15b + 4s = 99 equation 2
multiply equation 1 by 4 and equation 2 by 6
44b + 24s = 364 eqn 3
90b + 24s = 594 eqn 4
subtract equation 3 from 4
230 = 46b
b = 5
substitute for b in eqn 1
55 + 6s = 91
s = 6

[tex]\triangle CAB\cong \triangle ONP[/tex]
Step-by-step explanation:
Triangles [tex]\triangle CAB[/tex] and [tex]\triangle ONP[/tex] share two corresponding angles and the inclusive side between them. This is known as ASA (angle-side-angle) and does prove congruence. Therefore, [tex]\triangle CAB\cong \triangle ONP[/tex].
The four proofs of congruence include SSS (side-side-side), SAS(side-angle-side), ASA (angle-side-angle) and AAS (angle-angle-side). No other pair of triangles demonstrate any of these.

Two sides and the included angle of one triangle equal to the corresponding parts of the other one.
Two angles and the included side of one triangle equal to the corresponding parts of the other one.
All three sides of one triangle equal to the corresponding parts of the other one.
They are right triangles, and hypotenuse and one leg of one triangle equal to the corresponding parts of the other one.
They are right triangles, and hypotenuse and one acute angle of one triangle equal to the corresponding parts of the other one.
Therefore, the answer is true.

Jerome, kevin and seth shared a submarine sandwhich. Jerome ate 1/2 of the sandwich , kevin ate 1/3 of the sandwich, and seth ate the rest. What is the ratio of jerome's share to kevin's share to kevin's share to seth's share?
Given:
Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.
To find:
The ratio of jerome's share to kevin's share to seth's share.
Solution:
Jerome ate 1/2 of the sandwich. So,
Jerome's share = [tex]\dfrac{1}{2}[/tex]
Kevin ate 1/3 of the sandwich. So,
Kevin's share = [tex]\dfrac{1}{3}[/tex]
Seth ate the rest. So,
Seth's share = [tex]1-\dfrac{1}{2}-\dfrac{1}{3}[/tex]
= [tex]\dfrac{6-3-2}{6}[/tex]
= [tex]\dfrac{1}{6}[/tex]
The ratio of jerome's share to kevin's share to seth's share is:
[tex]\dfrac{1}{2}:\dfrac{1}{3}:\dfrac{1}{6}[/tex]
To simplify the ratio multiply the ratio by 6.
[tex]\dfrac{1}{2}\times 6:\dfrac{1}{3}\times 6:\dfrac{1}{6}\times 6[/tex]
[tex]3:2:1[/tex]
Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.

A camera has a listed price of $511.99 before tax. If the sales tax rate is 7.75%, find the total cost of the camera with sales tax included.
Round your answer to the nearest cent, as necessary,
Answer:
$551.70
Step-by-step explanation:
Price before tax= $511.99
Cost of the tax= 7.75/100×511.99
= $39.679
Total cost of the camera= $511.99+$39.679
= $551.669
≈ $551.70

The volume of a cylinder is 14,130 ft 3 . If the diameter is 30 feet, calculate the height of the cylinder
Answer:
V = PI*r2h
In plain english the volume of a cylinder can be calculated by squaring the radius, multiplying that value by PI, then multiplying by the height. You can also think of it as finding the area of a flat circle (PI * radius squared) and multiplying by the height to find volume.
Here is a step-by-step case that illustrates how to find the volume of a cylinder with a radius of 3 inches and a height of 5 inches. In this example PI will be 3.14.
V = pi * r2 * h
= pi * 32 * 5
= pi * 9 * 5
= 3.14 * 45
= 141.37 cubic inches
Step-by-step explanation:
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.
The height of the cylinder is given by h = 20 feet
What is a Cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is
Volume of Cylinder = πr²h
Surface area of cylinder = 2πr ( r + h )
where r is the radius of the cylinder
h is the height of the cylinder
Given data ,
Let the height of the cylinder be h
Now , the volume of the cylinder V = 14,130 feet³
The diameter of the cylinder d = 30 feet
So , the radius of the cylinder r = d/2 = 15 feet
And , Volume of Cylinder = πr²h
On simplifying , we get
14,130 = π( 15 )²h
Divide by 225 on both sides , we get
πh = 62.8
Divide by π on both sides , we get
h = 62.8 / 3.14
h = 20 feet
Therefore , the value of h is 20 feet
Hence , the height of the cylinder is 20 feet
