A restaurant sells sandwiches and will deliver for an additional cost. To have three sandwiches delivered, it costs $20. To have four sandwiches delivered, it costs $26. How many sandwiches can be delivered for $80?
Answer:
12 sandwiches
Step-by-step explanation:
If 3 sandwiches cost $20
Then x sandwiches cost $80
3----20
x----80
20x=3 x 80
20x=240
x=240/20
x=12 sandwiches
Give each trig ratio as a fraction in simplest form. First find the measure of the missing side using Pythagorean Theorem a2 + b2 = c2
Answer:
see step-by-step for full solution
Step-by-step explanation:
First use Pythagoras' Theorem to calculate the length of the missing leg PQ, where a and b are the legs and c is the hypotenuse of a right angled triangle.
a² + b² = c²
⇒ 14² + PQ² = 50²
⇒ 196 + PQ² = 2500
⇒ PQ² = 2500 - 196
⇒ PQ² = 2304
⇒ PQ = √2304 = 48
Therefore, the measure of the missing side PQ is 48.
Now use the 3 basic trigonometry ratios, where O = leg opposite to the angle, A = leg adjacent to the angle, and H = hypotenuse:
[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A} \\[/tex]
If angle = Q, then O = 14, A = 48, H =50. Therefore,
sin(Q) = O/H = 14/50 = 7/25
cos(Q) = A/H = 48/50 = 24/25
tan(Q) = O/A = 14/48 = 7/24
If angle = R, then O = 48, A = 14, H = 50. Therefore,
sin(R) = O/H = 48/50 = 24/25
cos(R) = A/H = 14/50 = 7/25
tan(R) = O/A = 48/14 = 24/7

Answer:
A square root of 11, 3.7, square root of 20, 4.8
Step-by-step explanation:
4.8
√20 = 4.47
3.7
√11 = 3.32
In order from least to greatest,
√11, 3.7, √20, 4.8.
The correct option is A.
What is ascending order?Putting numbers in ascending order simply means to do it from smallest to largest.
Given:
We have numbers,
4.8,
square root of 20 = 4.47,
square root of 11 = 3.32
And 3.7.
In order from least to greatest,
√11, 3.7, √20, 4.8.
Therefore, the expression is √11, 3.7, √20, 4.8.

Find the measure of the unknown segment (x) in each figure. Use theorem of tangent segment and secant segment.
Answer:
1. [tex]x[/tex] = 3√10 2. [tex]x[/tex] = 5 3. [tex]x[/tex] = 6√2
Step-by-step explanation:
Use Intersecting Secant-Tangent Theorem:
If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.
1. In this circle, DB is a tangent and DA is a secant. They intersect at point D.
So DB² = DC x DA
[tex]x[/tex]² = 5 x (5 + 13)
[tex]x[/tex]² = 90
[tex]x[/tex] = √90 = 3√10
2. In this circle, FE is a tangent and FH is a secant. They intersect at point F.
So FE² = FG x FH
10² = [tex]x[/tex] x 20
100 = 20[tex]x[/tex]
[tex]x[/tex] = 5
3. In this circle, NM is a tangent and NP is a secant. They intersect at point N.
So NM² = NO x NP
[tex]x[/tex]² = 4 x (4 + 14)
[tex]x[/tex]² = 72
[tex]x[/tex] = √72 = 6√2
#1
x²=5(13+5)x²=5(18)x²=90x=3√10#2

The volume of a cube is 512 cm3 . What is the area, in square centimetres, of each side of the cube?
Answer:
Step-by-step explanation:
V of a cube is s^3
V = 512
s = cube root of (V)
s = cube root of 512 cm^3
s = 8
The area of one face of the cube is s^2
s = 8
Area 1 face = 8^2
Area of 1 face = 64 cm^2

Which number should come next in the series? 13, 57, 911, 1315, 1719?
Answer:
2123
like 1+4=5
3+4=7
Step-by-step explanation:
All odd numbers beginning from one, in a series.
Also: Starting with 13, add 4 to each digit separately, and continue adding 4 to the result.
Answer:
Solution,
Finding;
Difference between each number
1719-1315=404
1315-911=404
911-57=854
57-13=44
Here,4 is being added to both digits of the number. So the next number will be 17+4=21 and 19+4=23 which is 2123. So the next number to this series will be 2123.
