Answer:
Área de un rectángulo = 150 cm²
El perímetro de un rectángulo = 50 cm
Step-by-step explanation:
Área de un rectángulo = largo × ancho (alto)
= 15 cm × 10 cm
= 150 cm²
El perímetro de un rectángulo = 2L + 2W
Donde L = longitud = 15 cm
W = Ancho = 10 cm
= 2 (15 cm) + 2 (10 cm)
= 30 + 20
= 50cm

Answer: (C) 308 cm^2
Step-by-step explanation: Flat surface area is the surface area that is not curved; in this case, it would be the two circular bases. The height is arbitrary as the height is not needed to calculate the area of the bases. The formula for the area of circular bases is πr^2. Let's plug the given values into the formula. (22/7)(7)^2=(22/7)(49)=154. 154 cm^2 is the area of one base. To find the area of both bases, simply multiply the area of one base by two. 154*2 is 308, therefore the answer is (C) 308 cm^2.
A bag contains 9 red, 6 green, 3 blue, and 2 yellow balls of the same size. A student chooses a colour and then draws a ball from the bag. If she draws a ball of her choice of colour she wins, if not the teacher wins. Who do you think will be the winner after 24 rounds, the student or the teacher
Answer:
the teacher will win becasue there are less numbers of colors to choose from one of the catagories then there are in total.

Please help me!! Perimeter: about ______ ft squared
Area: about ________ ft squared
Answer:
55.1 ft ; 236.7 ft^2
Step-by-step explanation:
radius = 7.5 ft
Perimeter of the semicircles = 2 * radius * pi = 2 * 7.5 * pi = 47,12389 ft
Perimeter of the rectangle = 4 * 2 = 8 ft
Total perimeter = 55,12389 ft
Area of the semicircles = radius^2 * pi = 7.5^2 * pi = 176,714587 ft^2
Area of the rectangle = 4 * 15 = 60 ft^2
Total area = 236,714587 ft^2

Step-by-step explanation:
Cos(140)=cos(180-40)=-cos(40)=-k
Answer:
Step-by-step explanation:
Sin (90 - A) = Cos A
Cos (90 + A) = -Sin A
Sin 50 = Sin (90 - 40)
= Cos 40
= k
Cos 140 = Cos (90 + 50)
= - Sin 50
= (- k)
Debbie has 12 blooms on her lemon tree on the first day she thinks to check it. Each day after that, she notices 3 additional blooms. How many blooms does she have after one week?
Answer:
33 blooms
Step-by-step explanation:
This can be set up by an equation. x represents the number of days and y represents the number of corresponding blooms. y = 3x + 12 is the equation, as 3 is the rate of change and 12 is the initial amount. One week is 7 days, so 7 can be plugged in for x. 21 + 12 = 33, so after one week, Debbie has 33 blooms.
An archery video game has an auto-aim feature.
An archer wants to hit point T but his bow is aimed at point A, which is 15 m away from T as shown. The
auto-aim feature also knows that the archer is 60 m away from T and 50 m away from A
How many degrees will the auto-aim feature adjust the shot?
Do not round during your calculations. Round your final answer to the nearest degree
Answer:12
Step-by-step explanation:
Based on the calculations, the number of degrees that the auto-aim feature would adjust the shot is 12°.
How to calculate the angle formed?Based on the triangle attached in the image above, we can deduce the following parameters:
Side AT = 15 m.
Side CA = 50 m.
Side CT = 60 m.
In this scenario, we would apply the cosine trigonometry function by using this mathematical expression:
AT² = CA² + CT² - 2(CA)(CT)COSθ
15² = 50² + 60² - 2(50)(60)COSθ
225 = 2500 + 3600 - 6000COSθ
6000COSθ = 6100 - 225
6000COSθ = 5875
θ = COS⁻¹(5875/6000)
θ = COS⁻¹0.9792
θ = 11.72 ≈ 12°

What are the coordinates of R on segments QS such that the ratio is 1:2. Q(-6,2) S(5,6)
Given:
The endpoints of a line segment QS are Q(-6,2) and S(5,6).
Point R divides the line segment QS in 1:2.
To find:
The coordinates of point R.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of that point are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
It is given that the endpoints of a line segment QS are Q(-6,2), S(5,6) and point R divides the line segment QS in 1:2. So, the coordinate of point R are:
[tex]R=\left(\dfrac{1(5)+2(-6)}{1+2},\dfrac{1(6)+2(2)}{1+2}\right)[/tex]
[tex]R=\left(\dfrac{5-12}{3},\dfrac{6+4}{3}\right)[/tex]
[tex]R=\left(\dfrac{-7}{3},\dfrac{10}{3}\right)[/tex]
Therefore, the coordinates of point R are [tex]\left(\dfrac{-7}{3},\dfrac{10}{3}\right)[/tex].

A circular cardboard piece is needed for the base of a volcano model. The volcano is 46 centimeters tall and has a volume of 800 cubic centimeters. Which equation can be used to find the area of the circular base? 46 = one-third (B) squared (800) 46 = one-third (B) (800) 800 = one-third (B squared) (46) 800 = one-third (B) (46)
Answer:
800 = 1/3(B)(46)
Step-by-step explanation:
Volume of a cone is [tex]1/3pir^2h[/tex]
we can set up an equation where V = 1/3pir^2h
Knowns :
V = 800
h = 46
Plug the knowns into the equation
800 = 1/3(pir^2)(46)
pir^2 is the area of a circle, which in this case is B
hope this helps
The equation which can be used to find the area of the circular base is 800 = 1/3(πr²)(46)
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that circular cardboard piece is needed for the base of a volcano model.
The volcano is 46 centimeters tall and has a volume of 800 cubic centimeters.
We have to find the equation which can be used to find the area of the circular base.
Volume of a cone is 1/3πr²h
V= 1/3πr²h
Plug in the values of volume and height in the above formula
V = 800
h = 46
800 = 1/3(πr²)(46)
Hence, the equation which can be used to find the area of the circular base is 800 = 1/3(πr²)(46)

Ahmad said that the volume of cone A is half the volume of cone B? Do you agree? Explain
Answer:
Yes, I agree
Step-by-step explanation:
See attachments for cone
Cone A
[tex]h = 2r[/tex]
Cone B
R = 2r
[tex]h=r[/tex]
The volume of a cone is
[tex]V = \frac{1}{3}\pi r^2h[/tex]
For cone A, we have:
[tex]V = \frac{1}{3}\pi r^2*2r[/tex]
[tex]V_A = \frac{2}{3}\pi r^3[/tex]
For cone B, we have:
[tex]V = \frac{1}{3}\pi *(2r)^2 * r[/tex]
[tex]V = \frac{1}{3}\pi *4r^2 * r[/tex]
[tex]V_B = \frac{4}{3}\pi r^3[/tex]
So, we have:
[tex]V_B = 2 * \frac{2}{3}\pi r^3[/tex]
Substitute [tex]V_A = \frac{2}{3}\pi r^3[/tex]
[tex]V_B = 2 * V_A[/tex]
Make VA the subject
[tex]V_A = \frac{1}{2}V_B[/tex]
Hence, I agree with Ahmad

Answer:
7 strips
Step-by-step explanation:
One way we can solve this is through guess and check. Let's start with 4 strips. If Joe's grandma makes 4 strips, she will have 0.75*4 = 3.00 yards of fabric. That's a really low amount of fabric. Let's double that to 8, where Joe's grandma would need 0.75*8 = 6.00 yards of fabric. That's really close! Let's remove one strip. 0.75*7 = 5.25 yards of fabric. Perfect! Joe's grandma can cut exactly 7 strips

In ΔMNO, m∠M = 57° and m∠N = 75°. Which list has the sides of ΔMNO in order from shortest to longest?
Answer:
B. MN, NO, OM
Step-by-step explanation:
Recall: In any triangle, the sides and the angles are related in the following way:
*The largest angle and the longest side are opposite each other
*The medium angle and the mid-sized side are opposite each other
*The smallest angle and the shortest side are opposite each other
In ∆MNO, we are given that
m<M = 57° which is opposite to side NO
m<N = 75° which is opposite to side OM
m<O = 180° - (75° + 57°) (sum of triangle)
m<O = 48° which is opposite to side MN
Therefore, we can write the order of shortest to longest side in relation to their opposite angles as follows:
MN, NO, OM
