Of 500 dogs at a dog show, 30% are male. 2/5 of the male dogs are over the age of 3. How many dogs are male and over 3 years?
Answer: 60 dogs are male and over 3 years out of total 150 male dogs.
Step-by-step explanation:
Total no. of dogs are 500
Males are 500 x 0.3 = 150
Over 3 years are 150 x 2/5 = 60
Answer:
Total number of dogs: 500
Percent that is male: 30
Over the age of 3: 2/ 5
30 % of 500 = 150
MAKE IT INTO A FRACTION
2= 60
5 = 150
60 of the dogs are male and over 3 years.

The 3D shape of the 5 cubes put to a 2D-plane will be representing the diagram A.
Answer: A
Step-by-step explanation:
This is because Option A has 5 cubes, as well as the model above which also has 5 cubes. When you change the angle of the way you are looking at Option A it will be similar to the plan above
(99^2-98^2)/197+(98^2-97^2)/195+(97^2-96^2)/193+ ... +(2^2-1^2)/3
plz help
Answer:
99
Step-by-step explanation:
(99^2-98^2)/197+(98^2-97^2)/195+(97^2-96^2)/193+ ... +(2^2-1^2)/3
each term can be written as:
(a²- b²)/(a+b)= (a+b)(a-b)/(a+b)= a-bso the sum will look as:
99 -98+ 98- 97 + 97- 96 + ... +2- 1= 99-1= 98(all middle terms get cancelled leaving only 99 and -1 in the equation)

Answer:
Option B.
Step-by-step explanation:
Continuous probability distribution : A probability distribution is called a continuous probability distribution, if its random variable X is a continuous variable and it can take infinite values (Real values).
Number of boxes cannot be a decimal value. So, it is not a continuous variable. Thus, option A is incorrect.
Temperature of a day is a continuous variable. So, temperature of a day can be represented using a continuous probability distribution. So, option B is correct.
Marks in a test paper cannot represent a continuous variable. Thus, option C is incorrect.
Number of students who uses the internet cannot be a fractional or decimal value. So, it is not a continuous variable. Thus, option D is incorrect.
Therefore, the correct option is B.

IMAGE 2: Find the value of the indicated trigonometric ratio sin β
IMAGE 3: Find the value of the indicated trigonometric ratio cot γ
IMAGE 4: Find the value of the indicated trigonometric ratio tan α (WORTH 30 POINTS!) Thanks!
Answer:
28.07° ; 70.53° ; 53.13° ; 36.87°
Step-by-step explanation:
Using PYTHAGORAS RULE :
IMAGE 1:
value of cos α equals :
cos α = Adjacent / Hypotenus
cos α = 15 / 17
cos α = 0.88235
α = cos^-1 (0.88235)
α = 28.07°
IMAGE 2:
sin β = Opposite / Hypotenus
sin β = 14√2 / 21
sin β = 0.9428
β = sin^-1(0.9428)
β = 70.53°
IMAGE 3:
From trigonometry :
cot = 1 / tan
Tan = Opposite / Adjacent
Therefore, Cot = Adjacent / Opposite
cot γ = 3/4
cot γ = 0.75
γ = cot^-1 (0.75)
γ = 53.13°
IMAGE 4:
tan α = Opposite / Adjacent
tan α = 15 / 20
tan α = 0.75
α = tan^-1 (0.75)
α = 36.87°

Natalia wants to attend Louisiana State University. One year at Louisiana State University costs approximately $24,000. She currently has $4,000 in savings. Natalia has received a one-time grant of $1,500 and an annual academic scholarship for $3,500. She plans to enroll in the work study program that will pay $12,000 annually for part-time work. How much will Natalia need to borrow in student loans in order to attend Louisiana State University for 4 years?
Answer:
He needs to borrow $28,500 to attend the University for 4 years.
Step-by-step explanation:
One year at the University costs $24,000. The total she has to pay are 4 * $24,000 = $96,000
minus the $4,000 she has in savings: $96,000 - $4,000 = $92,000
minus the $1,500 she received one time: $92,000 - $1,500 = $90,500
minus $3,500 per anual
4* $3,500 = $14,000
$90,500 - $14,000 = $76,500
minus $ 12,000 per anual
4 * $12,000 = $48,000
$76,500 - $48,00 = $28,500
A farmer needs to mix 8 ounces of fertilizer for every 10 pounds of soil. How many pounds of fertilizer will the farmer need to make a mix that contains 80 pounds of soil? (Remember- 16 ounces = 1 pound)
1 pound of fertilizer will do 20 pounds of soils (8 x2= 16 ounces = 1 pound)
80 pounds of soil / 20 pounds of soil = 4 pounds of fertilizer

Carmela wants to take out a loan for a car. Which benefit will Carmela receive if she makes a down payment when she obtains the loan?
A. a decrease in the total cost of the loan
B. no penalties for late payments
C. an increase in the loan term
D. an increase in the principal amount
Answer:
A) a decrease in the total cost of the loan
Step-by-step explanation:
plato/edmentum
Besides, there's very, very rarely no penalties for late payments and making a down payment wont prevent that. It wont increase the loan amount because you are paying more in advance. It also wont increase the principal amount, in fact, it decreases it.

Answer:
Brainliest!!
Step-by-step explanation:
See picture
Answer:
Step-by-step explanation:
a) While line crosses y axis, x = 0
Plugin x = 0 in the equation
y - 4*0 = 1
y = 1
(0 , 1)
b) line passes through the point (0, -3)
y = 2x + c
-3 = 2*0 + c
-3 = c
Equation: y = 2x - 3
y=2x -3 passes through (k,10)
10 = 2*k - 3
10 = 2k - 3
10 + 3 = 2k
13 = 2k
13/2 = k
k = 6.5

What are the coordinates of the image of L for a dilation with center (0,0) and scale factor 1/4?
Answer:
[tex]K' = (\frac{1}{4} ,0)[/tex]
[tex]L' = (\frac{1}{4} ,1)[/tex]
[tex]M' = (\frac{5}{4} ,1)[/tex]
[tex]N' = (\frac{5}{4} ,0)[/tex]
Step-by-step explanation:
Given
K(1,0)
L(1,4)
M(5,4)
N(5,0)
Scale Factor = 1/4
Dilation with center (0,0)
Required
New coordinates of the quadrilateral
To get the new coordinates, we simply multiply the scale factor with each coordinate;
This is done as follows;
[tex]If\ K =(1,0),\ then;[/tex]
[tex]K' = \frac{1}{4} * (1,0)[/tex]
[tex]K' = (\frac{1}{4} * 1,\frac{1}{4}*0)[/tex]
[tex]K' = (\frac{1}{4} ,0)[/tex]
[tex]If\ L =(1,4),\ then[/tex]
[tex]L' = \frac{1}{4} * (1,4)[/tex]
[tex]L' = (\frac{1}{4} * 1,\frac{1}{4}*4)[/tex]
[tex]L' = (\frac{1}{4} ,1)[/tex]
[tex]If\ M =(5,4),\ then[/tex]
[tex]M' = \frac{1}{4} * (5,4)[/tex]
[tex]M' = (\frac{1}{4} * 5,\frac{1}{4}*4)[/tex]
[tex]M' = (\frac{5}{4} ,1)[/tex]
[tex]If\ N =(5,0),\ then[/tex]
[tex]N' = \frac{1}{4} * (5,0)[/tex]
[tex]N' = (\frac{1}{4} * 5,\frac{1}{4}*0)[/tex]
[tex]N' = (\frac{5}{4} ,0)[/tex]
Hence, the coordinates of the dilated figure are:
[tex]K' = (\frac{1}{4} ,0)[/tex]
[tex]L' = (\frac{1}{4} ,1)[/tex]
[tex]M' = (\frac{5}{4} ,1)[/tex]
[tex]N' = (\frac{5}{4} ,0)[/tex]

Lydia graphed ΔLMN at the coordinates L (0, 0), M (2, 2), and N (2, −1). She thinks ΔLMN is a right triangle. Is Lydia's assertion correct? Yes; the slopes of segment LM and segment LN are opposite reciprocals. No; the slopes of segment LM and segment LN are not opposite reciprocals. Yes; the slopes of segment LM and segment LN are the same. No; the slopes of segment LM and segment LN are not the same.
Answer:
No; the slopes of segment LM and segment LN are not opposite reciprocals
Step-by-step explanation:
slope of LM: (2 - 0)/(2 - 0) = 1
slope of LN: (-1 - 0)/(2 - 0) = -1/2
Two lines are perpendicular when the multiplication of their slopes is equal to negative one, that is, they are opposite reciprocals. In this case:
slope of LM*slope of LN = 1*(-1/2) = -1/2
The correct option is
No; the slopes of segment LM and segment LN are not opposite reciprocals
The calculation is as follows:
slope of LM: [tex](2 - 0)\div (2 - 0)[/tex] = 1
And,
slope of LN: [tex](-1 - 0)\div (2 - 0)[/tex]= [tex]-1\div 2[/tex]
Here two lines should be perpendicular at the time when the multiplication of their slopes is equalivalent to negative one.
So,
= slope of LM × slope of LN
[tex]= 1\times (-1\div 2)\\\\ = -1\div 2[/tex]

b. six equilateral triangles
Step-by-step explanation:
The 6 interior angles of the hexagon are supplementary to the exterior angle and are 120 deg. ... Therefore the angles at the center is 360/6 = 60 degrees for each triangle. So all three angles of the six triangles are 60 deg each. So there are 6 equilateral triangles that form the regular hexagon.
