What is the ratio of the side length of the smaller square to the side length of the larger square?
FAST RESPONSE PLEASE!!!
Answer:
the smaller square length is 3cm
the larger square length is 6cm
hence their ratio will be 3:6
Simplify the ratio
we have our final answer to be 1:2
The required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Side of smaller square, a = 3
Side of the larger square, b = 6
According to the question,
The ratio of the side length of the smaller square to the side length of the larger square,
= a / b = 3 / 6
= 1 / 2
Thus, the required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.

The dial on an old telephone is a plastic ring 8cm in diameter with a4cm diameter hole in the center. Ten small dialing holes each of diameter 1.2cm are cut out of the ring
Answer:
Area of remaining plastic = 36.55 cm² (Approx.)
Step-by-step explanation:
Given:
Diameter of plastic dial of telephone = 8 cm
Diameter of middle hole = 4 cm
Diameter of ten small holes = 1.2 cm
Find:
Area of remaining plastic
Computation;
Radius of plastic dial of telephone = 8/2 = 4 cm
Radius of middle hole = 4/2 = 2 cm
Radius of ten small holes = 1.2/2 = 0.6 cm
Area of remaining plastic = Area of plastic dial - Area of middle hole - 10[Area of small holes]
Area of remaining plastic = π(4)² - π(2)² - π(0.6)²
Area of remaining plastic = π(16) - π(4) - π(0.36)
Area of remaining plastic = π[16 - 4 - 0.36]
Area of remaining plastic = π[11.64]
Area of remaining plastic = (3.14)(11.64)
Area of remaining plastic = 36.5496
Area of remaining plastic = 36.55 cm² (Approx.)

A) wants to makes 2.4kg of cookies
How much of each ingredient should he use.
B) using this recipe 10ph of syrup is needed to make 15 of these cookies
A)butter= 12
sugar = 9.6
syrup= 4.8
eggs= 2.4
What is ratio?A ratio indicates how many times one number contains another.
Given:
5:4:2:1
Let the common ratio be x
So, butter= 5x
sugar= 4x
syrup = 2x
egg= x
As, eggs= 2.4 kg
So, x= 2.4
Now,
butter= 5x = 5* 2.4 = 12
sugar= 4x = 4* 2.4 = 9.6

The formula to calculate arc length when central angle is in degrees =
Arc length = θ/360 × 2πr
r = radius = 1
θ = 81°
Hence:
Arc length in π =
= 81/360 × 2 × π × 1
= 162π/360
= 9π/20
Therefore, the arc length = 9π/20

Help, I dont get it, Like how do I do the division?
Answer:
Step-by-step explanation:
you actually dont have to do any division in this problem. since you know the area of the square and its depth, you simply multiply to two fractions, so [tex]\frac{25}{4} *\frac{8}{5}[/tex] when you multiply fractions all you do is multiply the tops and and bottoms, so 25 * 8=200 and 5 * 4=20, so the fraction is now 200/20, so when divide both sides by 20, the answer is 10. another way to demonstrate this in case you didnt understand is that you can rewrite your equation as [tex]\frac{25 * 8}{4 * 5}[/tex] then all you have to do is perform the opperation.

Answer:
614
Step-by-step explanation:
15 x 13 = 195 two times 195 x 2 = 390
4 x 15 = 60 two times 60 x 2 = 120
4 x 13 = 52 two times 52 x 2 = 104
104 + 120 + 390 = 614
Answer:
SA = 2(l·w)+2(w·h)+2(l·h)
SA = 614 sq in
Step-by-step explanation:
SA = 2(4x13)+2(13x15)+2(4x15)
= 2(52)+2(195)+2(60)
= 104 + 390 + 120
= 614

Step-by-step explanation:
The volume would be the Cone + Cylinder. So, use 1/3 x pi x r^2 x h and since the height is 6-3=3, you get 9 x 3.14 x 6 x 1/3 which is 56.52. The volume of the cylinder is pi x r^2 x h, which is 9 x 3.14 x 3, is 84.78. Now, add 56.52+84.78 = 141.3. Hope this helps

Answer:
-9
Step-by-step explanation:
Using the sum/difference property of logarithms, we can rewrite the expression given as:
log b^3 + log c^3 - log √(a^3) --> log √(a^3) can also be written as log a^1.5
Next, we can use the power property of logarithms, and rewrite it again as:
3log b + 3log c - 1.5log a
Now, we can substitute the values of log a, log b, and log c:
3(11) + 3(-9) - 1.5(10)
33 - 27 - 15
-9
Simplifying, we get -9 as the answer.

A. Bisecting any angle
B. The Koch curve
C. The Delian problem
D. Playfair's axiom
Answer: C: the Delian problem
Step-by-step explanation: the Delian problem includes doubling a cube which was a famous impossible problem
The most famous impossible problem from Greek antiquity is The Delian problem.
What is Greek antiquity?
The Greek difficulties of antiquity were a collection of geometric issues, and the only tools available to solve them were a compass and a straightedge. The only problems are:
Duplication of cubes.angle trisectionsquaring of circlesSolution:
The Delian problem, doubling the cube, is considered one of the most famous impossible problems from Greek antiquity. Two others are the trisection of the general angle and squaring of a circle(also a famous problem)
Whereas the other options like the Koch curve, bisecting any angle and playfair's axiom is known for its possibilities.
Hence the Delian problem is the most famous impossible problem from Greek antiquity.

Find the roots of f(x)=x^2+10x−96
I really just need the step by step-
cant find out how to get the answer
Answer:
x = -16 or x = 6
Step-by-step explanation:
To find the roots of a polynomial function, set the polynomial equal to zero and solve for x.
x² + 10x - 96 = 0
We need to factor the left side. The left side is a quadratic polynomial whose first coefficient is 1. We need two numbers whose product is -96 and whose sum is 10. The numbers are 16 and -6.
(x + 16)(x - 6) = 0
If a product of two factors equals zero, then one factor or the other or both must equal zero.
x + 16 = 0 or x - 6 = 0
x = -16 or x = 6
