Disregard Above
Use Picture
Answer:
ON MONDAY: 35 mosquitos.
ON TUESDAY: 6 flies.
Step-by-step explanation:
As you can see in the diagram, the frog eats 3 flies for every 7 mosquitoes (for lunch). Then you can expresed this ratio as following:
3:7 or [tex]\frac{3}{7}[/tex]
Based on the table:
-If the frog eats 15 flies on monday, then the number of mosquitos that it eats can be calculated as following:
[tex]\frac{3}{7}=\frac{15}{mosquitoes}\\\\mosquitoes=\frac{15*7}{3}\\\\mosquitoes=35[/tex]
-If the frog eats 14 mosquitoes on tuesday, then the number of flies that it eats can be calculated as following:
[tex]\frac{3}{7}=\frac{flies}{14}\\\\flies=\frac{14*3}{7}\\\\flies=6[/tex]
What is the area of this triangle?
We use the vertical side as the base: it is a vertical segment, so it's length is the difference of the y coordinates of its endpoints:
[tex] b = y_2-y_1[/tex]
The height would be the segment starting from [tex](x_3,y_3)[/tex], perpendicular to the base. Since this is a horizontal segment, its length is the difference of the x coordinates of its endpoints:
[tex]h = x_3-x_1[/tex]
So, the area is given by
[tex]A = \dfrac{bh}{2} = \dfrac{(y_2-y_1)(x_3-x_1)}{2}[/tex]
Answer:
A = 18
Step-by-step explanation:
Drop a perpendicular from (x₃, y₃) to point A on the opposite side.
The vertical line containing A is the base of the triangle, and the horizontal line is its height,
The formula for the area of a triangle is
A = ½bh
b = y₂ - y₁ = 6
h = x₃ - x₁ = 6
A = ½ × 6 × 6 = 18
The area of the triangle is 18.
What is the length of segment EF?
EF = square root of 58 end square root
EF = three square root of 10 end square root
EF = 9
EF = 90
Answer:
[tex]EF=3\sqrt{10}\ units[/tex] ------> three square root of 10
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
In this problem we have
[tex]E(-1,-1)\\F(8,-4)[/tex]
substitute the values
[tex]EF=\sqrt{(-4+1)^{2}+(8+1)^{2}}[/tex]
[tex]EF=\sqrt{(-3)^{2}+(9)^{2}}[/tex]
[tex]EF=\sqrt{90}\ units[/tex]
[tex]EF=3\sqrt{10}\ units[/tex]
Find the radius of a circle with a circumference of 35 π yards
Answer:

Be awesome! Is a new cross fit gym in town. The gym is almost set to its grand opening. The contractors are doing flooring. Gymnasium flooring cost $4.50 per square foot. The gym has 2 main rooms, one in a shape of a regular hexagon and the other in a shape of a regular nonagon. Both rooms have side lengths of 50 feet. Which of the following represents the closest estimate for the total of gymnasium flooring material? A: 29229 B: 40000
C: 69545 D: 98774
Answer:
D
Step-by-step explanation:
We need to find total area of the two rooms (hexagon and nonagon) and then multiply that by 4.5 to get total cost.
Area of Hexagon = [tex]\frac{3\sqrt{3}a^{2} }{2}[/tex]
Where a is the side length (which is 50)
Hence,
Area of Hexagon = [tex]\frac{3\sqrt{3}a^{2} }{2}=\frac{3\sqrt{3}(50)^{2} }{2}=6495.2[/tex]
Also, area of Nonagon is given by [tex]6.1818*s^2[/tex]
Where s is the length of the side
Hence,
Area of Nonagon = [tex]6.1818*s^2=6.1818*(50)^2=15,454.5[/tex]
Total floor area = 6495.2 + 15,454.5 = 21,949.7
Hence,
Total Cost = 21,949.7 * 4.5 = 98,773.65

Answer:
To find the answer, you must multiply/divide the amount in cups by calories per cup.
Step-by-step explanation:
Butter only has 0.3 cups, so The calories will only be 30% of what is written down. 30% of 1627= 488.1 calories
Marshmallows is 4.25 times larger then the calories per cup, so now you'll have to multiply.
4.25*159=675.75 calories
Finally, Cereal is 5.5 times larger then the calories per cup, so we will multiply again.
5.5*101=555.5 calories
Finally, add all the number together to find the total amount of calories in the marshmallow treats.
555.5+675.75+488.1=1,719.35 calories
There is a total of 1,719.35 calories in the marshmallow treats.

(4/5+3/5)+3.5*5
= 7/5+7/2*5
= 7/5+35/2
= 14/10+175/10
= 189/10
= 18.9
Answer:
The value of the expression is 18.9
Step-by-step explanation:
The expression is:
[tex]\bigg( \frac{4}{5}+\frac{3}{5}\bigg)+3.5\times 5[/tex]
The first step is to solve the parenthesis. As both fractions have the same denominator, the numerators must be added:
[tex]\bigg( \frac{4+3}{5}\bigg)+3.5\times 5[/tex]
[tex]\bigg( \frac{7}{5}\bigg)+3.5\times 5[/tex]
The second step is to perform the division between 7 and 5, it is 1.4:
[tex]1.4+3.5\times 5[/tex]
The third step is to perform the multiplication between 3.5 and 5, it is 17.5:
[tex]1.4+17.5[/tex]
The last step is to perform the sum, it is 18.9:
[tex]1.4+17.5=18.9[/tex]

The total surface area for the given prism is 808 square inches.
The question asks to calculate the surface area of a rectangular prism in square inches. The dimensions given are 1 1/2 ft (length), 2/3 ft (width), and 5/6 ft (height). To convert these measurements to inches, we multiply by 12 since there are 12 inches in a foot. Thus, the dimensions in inches are:
Length: 1 1/2 ft x 12 = 18 inchesWidth: 2/3 ft x 12 = 8 inchesHeight: 5/6 ft x 12 = 10 inchesTo find the surface area, we calculate the area of each face and then sum them:
Area of the front/back faces: Length x Height = 18 inches x 10 inches = 180 square inches (two faces, so 2 x 180 = 360 square inches)Area of the top/bottom faces: Length x Width = 18 inches x 8 inches = 144 square inches (two faces, so 2 x 144 = 288 square inches)Area of the side faces: Width x Height = 8 inches x 10 inches = 80 square inches (two faces, so 2 x 80 = 160 square inches)Now, add up all the areas of the faces to get the total surface area:
Surface Area = 360 + 288 + 160 = 808 square inches.

Which graph represents an exponential function?
Answer:
The first graph.
Step-by-step explanation:
An exponential function has a graph that is a smooth curve; it either increases at an ever increasing rate or decreases at an ever increasing rate.
The only graph that fits these characteristics is the first one.
Answer:
First graph is the exponential function
Step-by-step explanation:
The x value of exponential function is all real numbers
x can take any value positive or negative numbers
In the first graph , as x value increases the graph goes down
The first graph is an exponential function .
Second graph is the cubic function as the graph goes from left and it goes down on the right .
Third graph is an rational function because we have two graph on both sides of vertical asymptote
The fourth graph is not an exponential function as the domain is not all real numbers.

Answer:
JMK = 54
JKH = 126
HLK = 90
HJL = 27
LHK = 63
JLK = 27
Step-by-step explanation:
Just use 180 for total angles in each triangle. Vertical angles mean the opposite to 126 is 126 and the other two that make up the inner vertices are (360- 126*2)/2 = 54
So, 126, `16, 54 , 54 are the inner angles in the circle. Just go from there.

. Evaluate the following expression: 24 ÷ 3 + 7 ⋅ 2 – 15 ÷ 5 + 6 ⋅ 2 A. 31 B. –31 C. 30 D. 21
To evaluate the expression, we follow the order of operations (PEMDAS). The result of the expression is 31.
Explanation:To evaluate the expression 24 ÷ 3 + 7 ⋅ 2 – 15 ÷ 5 + 6 ⋅ 2, we need to follow the order of operations, also known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, we perform the division: 24 ÷ 3 = 8.Next, we perform the multiplication: 7 ⋅ 2 = 14 and 6 ⋅ 2 = 12.Now, we can write the expression with the values we found: 8 + 14 - 15 ÷ 5 + 12.Then, we perform the division: 15 ÷ 5 = 3.Finally, we perform the addition and subtraction from left to right: 8 + 14 - 3 + 12 = 31.Therefore, the evaluated expression is equal to 31.
Which factor pair has a product of 75?
A) 25 and −3
B) −15 and 5
C) −75 and 1
D) −25 and −3
I give you a lot of points if you do!!
Answer:
D
Step-by-step explanation:
Remembering that the product of 2 negatives is positive, then
- 25 × - 3 = 75 → D
Final answer:
Upon examining the factor pairs given in the options, none of them correctly multiply to a positive 75. There seems to be a typo in the options as none matches the requirement for the product to be 75. Most likely, the correct factor pair is missing or misrepresented.
Explanation:
The question asks to identify which factor pair has a product of 75. To find factors of 75, we look for pairs of numbers that multiply together to give the product of 75. Remember, the product of two negative numbers is positive.
Option A (25 and -3) does not give 75 as a product because 25 multiplied by -3 is -75.
Option B (-15 and 5) gives us a product of 75, since -15 multiplied by 5 is -75 (but we are looking for a positive 75).
Option C (-75 and 1) is incorrect because it results in -75, not 75.
Option D (-25 and -3) is also incorrect, as the product of two negative numbers would be positive, but it results in +75.
However, upon reviewing the options provided, it appears none of them correctly multiply to a positive 75. Most likely, there is a typo in the question or the options presented. In mathematics, finding factors of a number means identifying two numbers that, when multiplied together, give the original number. While option B's multiplication gives a product of -75, it is close to our target; we need a positive value, i.e., 75, not -75.

An auditorium has three levels. Level 1 seats 3,577 people, Level 2 seats 5,214 people, and Level 3 seats 5,879 people. How many seats are in all three levels combined? A. 8,991 B. 14,670 C. 14,970 D. 14,370
3577+5214+5879
=8791+5879
=14670
Answer
B. 14,670
The total number of seats in all three levels of the auditorium is calculated by adding the number of seats on each level, resulting in 14,670 seats.
To calculate the total number of seats in all three levels of the auditorium, we add the number of seats available on each level together. The calculation is as follows:
Level 1: 3,577 seats
Level 2: 5,214 seats
Level 3: 5,879 seats
Add these numbers to get the total:
3,577 + 5,214 + 5,879 = 14,670 seats
Therefore, the correct answer is B. 14,670, which is the combined number of seats in all three levels of the auditorium.

Answer: Reserved = 431, General Admission = 1356
Step-by-step explanation:
Let x represent the Reserved tickets.
Let y represent the General Admission tickets.
Cost Equation: 4x + 3y = 5792
Quantity Equation: x + y = 1787
Use Elimination Method:
4x + 3y = 5792 → 1(4x + 3y = 5792) → 4x + 3y = 5792
x + y = 1787 → -3( x + y = 1787) → -3x - 3y = -5361
x = 431
Now substitute x = 431 into one of the original equations:
x + y = 1787
431 + y = 1787
y = 1356
