I'm not the smartest but um does anybody know what my teacher means by this? Do I do all the evens or:
"You dont need to do ALL the evens...do EVERY OTHER EVEN, that way there are only 15 problems"
Answer:
This is the even numbers out of 100. So Do every other one so in you case 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30.And all them problem you do add up to 15 total of what you completed( why they said there will only be 15 problems AKA the ones you solve)

Step-by-step explanation:
Q2. In a camp food was enough for 400 people for 23 days. If 60 more people joined the camp, find the number of days the food will last?
Q3. Given that y is directly proportional to x and that y= 40 when x= 200, find the value of
(a) y when x= 15
(b) x when y= 8
Q4. If y is inversely proportional to x and that y= 8 when x= 30, find the value of:
(a) the value of y when x= 4
(b) the value of x when y= 360
Answer:
Q2)
We have food for 400 people, and it will last for 23 days.
Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:
23 days = K/400 people.
Then we get:
(23 days)*(400 people) = K = 9200 days*people.
Now if we increase the number of people by 60, we get.
people = 460
Then the number of days that this will last is:
D = (9200 days*people)/460 people = 20 days.
The food will last for 20 days.
Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:
40 = k*200
With this, we can find the value of k
40/200 = k = 0.2
Then the proportional relationship is:
y = 0.2*x
a) We need to replace x by 15.
y = 0.2*15 = 3
y = 3
b) We need to replace y by 8.
8 = 0.2*x
8/0.2 = x = 40
x = 40
Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.
Then we get:
8 = k/30
Then the value of k is:
8*30 = k = 240
then the relationship is:
y = 240/x
a) we need to replace x by 4
y = 240/4 = 60
y = 60
b) we need to replace y by 360
360 = 240/x
360*x = 240
x = 240/360 = 0.666...
x = 0.666...

What is the value of x and y?
Answer:
x = 9 ; y = 18
Step-by-step explanation:
This is a 30° 60° 90° triangle meaning the length of the big leg will be the value of the small leg times √3 and the hypotenuse will be double the length of the small leg.
Answer:
x = 9
y = 18
Step-by-step explanation:
tan(60) = 9 radical 3 / x
x = 9 radical 3 / tan(60)
x = 9
a² + b² = c²
9² + 9radical3² = c²
324 = c²
c = 18
y = 18

Answer:
-1
Step-by-step explanation:
Annie wants to create a right triangle with side lengths 12 centimeters, 35 centimeters, and
37 centimeters.
Is this possible? Why or why not?
Yes, because 12 + 35 is not equal to 37.
Yes, because 12? + 352 is equal to 372
No, because 12 + 35 is greater than 37.
No, because 12? + 352 is less than 372.
Answer: yes because 12^2+35^2=37^2

2+[tex]2+\frac{3}{4}x=\frac{5}{12}[/tex]
Answer:
x = -19/4
Step-by-step explanation:
Given the equation 2+3/4x = 5/12. We are to find the value of x
2+3/4x = 5/12.
3/4 x = 5/12 - 2
3/4 x = (5-24)/12
3/4 x = -19/12
Cross multiply
3x * 12 = -19 * 4
36x = -76
x = -76/36
x = -19/4

What is the volume of a cube with an edge length
of 2/3 foot?
Answer:
V= 512 inches or, 42.67 feet
Step-by-step explanation:
So a cube has the same length on all sides so you would multiply length times with times area or V = a^3
So, 2/3 foot is equal to 8 inches so you would do V = 8^3 which would get you the answer,
In ΔFGH, the measure of ∠H=90°, HG = 56, FH = 33, and GF = 65. What ratio represents the cosine of ∠G? ASAP PLS
The value of ratio which represents the cosine of ∠G is,
⇒ cos G = 56/65
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
In ΔFGH,
The measure of ∠H=90°, HG = 56, FH = 33, and GF = 65.
Now, By the formula;
⇒ cos θ = Base / Hypotenuse
Hence, We get;
⇒ cos G = GH / GF
⇒ cos G = 56/65
Thus, The value of ratio which represents the cosine of ∠G is,
⇒ cos G = 56/65

The Patel family looks at map to plan their family vacation. They plan to travel from Smithville to Jonesville, which are 3 3/4 inches apart on the map. Then they plan to travel from Jonesville to Clarksville, which are 5 1/4 inches apart on the map. The scale on the map is 1/2 inch equals 4 miles. What is the actual distance the Patel family will travel by the time they reach Clarksville? Enter your answer in the box
Answer: 72 miles
Step-by-step explanation:
The total distance from Smithville to Clarksville will be:
= 3 3/4 + 5 1/4
= 9 inches
Since the scale on the map is:
1/2 inch = 4 miles
1 inch = 4 × 2 = 8 miles
Therefore, 9 inches will be:
= 9 × 8 = 72 miles
The actual distance that the Patel family will travel by the time they reach Clarksville will be 72 miles.

If 40% of the students in the class are boys, and if there are 15 girls in the class, then how many students are in the class? * 1 point
Answer:
25
Step-by-step explanation:
15/6.0=2.5
2.5x4=10
2.5x6=15
10+15=25
10 boys and 15 girls
Answer:
25
Step-by-step explanation:
Let's set up "x" as the total number of students. So now we can set up an equation:
40%x+15=x rewritten as:
.4x+15=x Subtract .4x from both sides will give us:
15=.6x Now divide each side by .6 to be:
25=x Therefore we know there are 25 students in the class.
