Answer:
Step-by-step explanation:
1. 1923.25
2.about 3846.5 yards
3.219.91
4.639.82
Answer: See below
Step-by-step explanation:
1) 1/2 x 3.14 x 35^2
1/2 x 3.14 x 1225
1/2 x 3846.5
A = 1923.25 yd^2
2) (3.14)r^2
(3.14) (35)^2
3846.50 yd^2
3) P = d + (3.14)r^2
P = 70 + (3.14) (35)
P = 70 + 109.90
P = 179.90 yd
4) P = 2( l + w)
P = 2 (70 + 100)
P = 2 (170)
P = 340
Perimeter of the square minus the perimeter of the circle.
340 - 179.90 = 160.10 yd

Answer:
117 ft³
Step-by-step explanation:
The tent is composed of a cuboid and a triangular prism
V ( cuboid) = 6 × 8 × 2 = 96 ft³
V(prism) = Ah ( A is the area of triangle and h is length )
= [tex]\frac{1}{2}[/tex] × 6 × (5.5 - 2) × 2
= 3 × 3.5 × 2
= 21 ft³
Total volume = 96 + 21 = 117 ft³
Jason has saved 41% of what he needs to buy a 73$ skateboard . Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly
Answer:
No, Jason did not solve correctly
Step-by-step explanation:
Jason has saved 41% of what he needs to buy a 73$ skateboard.
Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly
Let compare both statements
50% of 70 = 70 ÷ 0.5 (140)
50% × 70 = 140
50/100 × 70 = 140
35 ≠ 140

Answer:
x = 12.48
y = 13.22
Step-by-step explanation
Im not sure if its correct
10^2 + b^2 = 16^2
100 + b^2 = 256
b^2 = √156
b = 12.48
b= 12 ( If needed to round to the nearest whole number)
a^2 + 15^2 = 20^2
a^2 + 225 = 400
a^2 = √175
a = 13.22
a = 13 ( If needed to round to nearest whole number)

Answer:
y - (-9) = -10(x - 1)
Step-by-step explanation:
(1, -9) and (-10, 101)
Slope:
m=(y2-y1)/(x2-x1)
m=(101+9)/(-10-1)
m=110/(-11)
m = -10
Point-slope:
y - y1 = m(x - x1)
y - (-9) = -10(x - 1)
Shiva has 1.95 pounds of meat. She uses 0.13 pound of meat to make one hamburger. How many hamburgers can Shiva make with the meat she has?
Answer:

Check
0.13 x 15 = 1.95
Answer:
[tex] \bf \huge \: 15[/tex]
Step-by-step explanation:
Given that :Shiva has 1.95 pounds of meat.She uses 0.13 pound of meat to make one hamburger.to find :How many hamburgers can Shiva make with the meat she has ?explanation :⟼ total meat = 1•95 pounds
⟼ use meat to make a hamburger = 0•13 pounds
⟼ how many hamburgers shiva make with the total meat = total meat / use meat to make a hamburger
⟼ how many hamburgers shiva make with the total meat = 1•95 / 0•13
⟼ how many hamburgers shiva make with the total meat = 15 hamburgers .
∴ shiva make 15 hamburgers with 1•95 pounds meat.
verification :let take shiva make 15 hamburgers with 1•95 pounds meat.
⟼ 0•13 × 15 = 1•95
⟼ 1•95 = 1•95

× 7 = 35
× 7 = 42
× 7 = 49
× 7 = 56
× 7 = 63
× 7 = 70
The number of points Jaden scored in a game less than 45, and a multiple of 7 is 35 points
How to find how many points Jaden scored?The multiples of 7 are;
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105......

Step-by-step explanation:
A bag of sweets contains only mints, sherberts and toffees.
The ratio of the number of mints to sherberts is 2:3.
The ratio of the number of sherberts to toffees is 7:5.
What fraction of the sweets are sherberts?
The fraction of the Sweets are Sherberts is 21/50
What is mathematical expression?
When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions as yet unlearned, the resulting combination of mathematical symbols is called a mathematical expression.
Mints:Sherbets = M:S = 2:3
Sherberts:Toffees = S:T = 7:5
Mints:Sherberts:Toffees = M:S:T = 2*7 : 7*3 : 3*5 = 14:21:15
Total sweets = 14+21+15 = 50 (Adding all the fractions after multiplying)
Therefore, the fraction of the Sweets are Sherberts = 21/50

3. When should points of intersection be included within the feasible region of a system of nonlinear inequalities
and why
Answer:
Points of intersection should be included within the feasible region (the solution set) of a system of nonlinear inequalities when the boundary lines that create the point are solid. A dashed line indicates that the points are not included in the solution set. Therefore, if one boundary line is dashed and one is solid, the point of intersection will not be included within the feasible region.
Step-by-step explanation:
Points of intersection should be included within the feasible region of nonlinear inequalities when the boundary lines that create the point are solid.
What is Inequality?This is defined as an expression in which the sides are not equal to each other.
The presence of boundary lines which have dashed and solid ones, the point of intersection will not be included within the feasible region.
