2) There are 40 boys and 16 girls in a class of students. What is the ratio of girls to students?
Add boys and girls together for total students:
40 + 16 = 56 total students
Girls to total students is 16/56
Divide both numbers by 8 to get 2/7
The ratio is 2/7

Answer:
the x-intercepts are at
x = -3
x = 0
x = 1
Step-by-step explanation:
ask the points, where the functional value is 0.
2x³ + 4x² - 6x = 0
we see that every term contains an expression of x. so, we can simplify this
x × (2x² + 4x - 6) = 0
so, one solution is plainly visible : x=0
for the other solutions we need to solve the square equation
2x² + 4x - 6 = 0
or even simpler
x² + 2x - 3 = 0
the solution of a square equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a=1
b=2
c=-3
x = (-2 ± sqrt(2² - 4×1×-3))/(2×1) = (-2 ± sqrt(4 + 12))/2 =
= (-2 ± sqrt(16))/2 = (-2 ± 4)/2 = -1 ± 2
x1 = -1 + 2 = 1
x2 = -1 - 2 = -3

you have no calculator ?
since you clearly have a computer or smart phone - there are calculator apps on all of them.
you really just need to use the given numbers and multiply and add them following the formula. so, what is your problem ?
anyway,
2pi×r×h + 2pi×r²
h = 5.9
r = 1.3
2pi × 1.3 × 5.9 + 2pi × 1.3² = 2pi × 7.67 + 2pi × 1.69 =

What is the ratio of 2:5
Step-by-step explanation:
The ratio is 2 to 5 or 2:5 or 2/5. All these describe the ratio in different forms of fractions. The ratio can consequently be expressed as fractions or as a decimal.
A ratio of 2 : 5 states a comparison between two quantities.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, a ratio 2 : 5.
Suppose it is a ratio of no. of pens to no. of pencils.
So, a ratio 2 : 5 states for every 2 pens there are 5 pencils out of 7 pen and pencils.
We can also write no. of pens = 2/(2+ 5) = 2/7 and for pencils it is 5(2+5)
= 5/7.
Generally, ratios are in simplest form we can have more pens and pencils here but it must be in the multiple of 7.

Answer with Step-by-step explanation:
Complete question:
The coordinates of the vertices of the triangle are (-8,8),(-8,-4), and. Consider QR the base of the triangle. The measure of the base is b = 18 units, and the measure of the height is h = units. The area of triangle PQR is square units.

Consider the quadratic function y = 0.3 (x-4)2 - 2.5
Determine the axis of symmetry, x =
Answer:
[tex]x=4[/tex]
Step-by-step explanation:
We have the quadratic function:
[tex]\displaystyle y=0.3(x-4)^2-2.5[/tex]
And we want to determine its axis of symmetry.
Notice that this is in vertex form:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola.
From our function, we can see that h = 4 and k = -2.5. Hence, our vertex is the point (4, -2.5).
The axis of symmetry is equivalent to the x-coordinate of the vertex.
The x-coordinate of the vertex is 4.
Therefore, the axis of symmetry is x = 4.
Tim and Al are bricklayers. Tim can construct an outdoor grill in 5 days. If Al helps Tim, they can build it in only 3 days. How long
would it take Al to build the grill alone? Write your answer as an integer, simplified fraction, or mixed number.
It would take Al
days to build the grill alone.
Answer:
It would take Al 7.5 days to build the grill alone.
Step-by-step explanation:
Since Tim and Al are bricklayers, and Tim can construct an outdoor grill in 5 days, and if Al helps Tim, they can build it in only 3 days, to determine how long would it take Al to build the grill alone should be done the following calculation:
1/5 + X = 1/3
0.20 + X = 0.333
X = 0.333 - 0.20
X = 0.1333333
X = 1 / 7.5
Therefore it would take Al 7.5 days to build the grill alone.

y = mx + b
-10 is b because it´s the y intercept (the y value when x is 0).
now, the slope (m) is rise/run:
this is easier graphed, but you can see that the run is 3 (moving sideways on the x axis) and the rise is 2 (going up or down) so its 2/3.
because we are going down on the y axis, the slope is negative (so is the y intercept).
So y = -2/3 -10 is the answer.
Janelle says that lines l and m are skew lines.
Planes B and A intersect. Plane B is vertical and contains vertical line n. Plane A is horizontal and contains horizontal line m. Line m and n are perpendicular. Line l is on plane A and it is slightly diagonal.
Is Janelle correct?
B.. No, because the lines are in the same plane.
Remember to take breaks. It can be really really skew but its going to be their tm. Maybe with more assignments but still. happy learning.
Ayo whats good

From a set of 5 nickels, 10 dimes and 15 quarters, six coins are removed at random without replacement.
a. Find the probability of not removing 6 quarters.
b. Find the probability of removing exactly 2 nickels, 2 dimes and 2 quarters.
Answer:
(a) 1 - (15 C 6) / (30 C 6)
(b) (5 C 2) x (10 C 2) x (15 C 2) / (30 C 2)
Step-by-step explanation:
Number of nickels = 5
Number of dimes = 10
Number of quarters = 15
(a) The probability of getting 6 quarters
= (15 C 6) / (30 C 6)
So, the probability of not getting 6 quarters = 1 - (15 C 6) / (30 C 6)
(b) Probability of getting 2 nickels , 2 dimes and 2 quarters
= (5 C 2) x (10 C 2) x (15 C 2) / (30 C 2)

Answer:
Step-by-step explanation:
a = 5
b = 15
c = ?
c^2 = a^2 + b^2
c^2 = 5^2 + 15^2
c^2 = 25 + 125
c^2 = 250
sqrt(c^2) = sqrt(250)
c = sqrt(250)
Find the first derivative for y = f(x). fox ) 3x² -5x-1 at a Pocat where a = 4
Answer:
Step-by-step explanation:
f(x) = 3x² -5x - 1
f'(x) =2*3x - 5*1 +0
= 6x - 5
f'(4) = 6*4 - 5
= 24 - 5
= 19
Wade has a test score of 77% on his first test and 65% on his second test. What must he score on a third test to have an average of 80% overall?
93%
98%
89%
None of these choices are correct.
Answer: 98%
Step-by-step explanation:
The third test score = x[tex]\frac{77+65+x}{3} =80\\\frac{142+x}{3} =80\\142+x=80*3\\x=240-142=98[/tex]
if x can be divide by 7 and 9 without leaving a remainder, it can also divided by which number without leaving a remainder
Answer:
all counting numbers except one

In a certain region, the probability of a baby being born a is instead of 0.5. Let A denote the event of getting a when a baby is born. What is the value of ?
Answer:
[tex]P(\bar A) = 0.5[/tex]
Step-by-step explanation:
Given
[tex]P(A) = 0.5[/tex]
Required
[tex]P(\bar A)[/tex]
To do this, we make use of complement rule:
[tex]P(\bar A) = 1 - P(A)[/tex]
So, we have:
[tex]P(\bar A) = 1 - 0.5[/tex]
[tex]P(\bar A) = 0.5[/tex]
Can someone do these for me and list the number because I’m struggling rn. And I’m having a breakdown lol.
Answer:
Step-by-step explanation:
First remove the parentheses.
As the sign outside the second parentheses is a + then the signs of the terms inside stay the same.
So the first one + (-3x +2) is just -3x + 2.
All the others on the left column are answered in the same way.
No. 4:
(-2x + 10 + (-8x - 1) Just remove the parentheses, we get:
-2x + 10 - 8x - 1 (we leave out the + before the second parentheses).
= -2x - 8x + 10 - 1
= -10x + 9
6. 8x + 8 + ( -6x - 1)
= 8x + 8 - 6x - 1
= 8x - 6x + 8 - 1
= 2x + 7.
- the other expressions on the right side column are solved in the same way.
