C 23 to 13
D 23 to 10
Answers
Answer:
13 to 10
Step-by-step explanation:
13 boys, 10 girls
13:10
The ratio of boys to girls in the classroom is 13:10
hence option B is correct
According too the given situation
The number of boys in the classroom = 13
The number of girls in the classroom = 10
Ratio is a quantitative relationship between two numbers showing a comparable form of magnitudes of both the numbers/quantities.
Let "a" and "b" be two numbers then the Ratio of "a" and "b" is shown as formulated in equation (1)
[tex]\rm r = a:b ........(1)[/tex]
The ratio of two numbers can be found out in simplest form by dividing these two numbers such that the division results in positive natural numbers for both the quantities.
So we can conclude that the ratio of boys to girls in the classroom are
[tex]\rm \dfrac{Boys }{Girls } =\dfrac{13}{10} \\\\Boys : Girls = 13:10 \\[/tex]

In rectangle EFGH, EH I FG and EH crosses the y-axis at (0.-2). If the equation of the line containing FG is x + 3y = 12, write the equation of the line containing EH in slope- intercept form. Show your work to justify your answer.
Answers
Answer:
y = (-1/3)x - 2
Step-by-step explanation:
First we should put the equation for FG into slope intercept form, which is y = mx + b. For this step, just solve for the y in the equation, which should be y = (-1/3)x + 4.
Next, since we know that FG and EH are parallel, their slopes must also be the same. We also know the (0, -2) is a point on EH, and also happens to be the y-intercept. Therefore, we can plug it back into the slope intercept equation and get y = (-1/3)x - 2, since the m is the same and the -2 is just the y-intercept given in the problem.
In triangle ABC, M is the midpoint of AB. Let D be the point on BC such that AD bisects angle BAC, and let the perpendicular bisector of AB intersect AD at E. If AB = 44, AC = 30, and ME = 10, then find the area of triangle ACE.

The area of Triangle ACE from the given diagram is; 150 sq.units
What is the area of the triangle?We are given;
AB = 44
AC = 30
ME = 10
Now, to find the area of triangle ACE, we need to know the length KE where K is the midpoint of AC.
Now, since AD bisects angle BAC. This means that ∠KEA = ∠MEA.
By ASA Congruence Postulate, we can say that; ΔAEK ≅ AEM
Thus, we can say that KE = ME = 10
Formula for area of triangle is;
A = ¹/₂ * base * height
where;
base = AC = 30
Height = KE = 10
Thus;
A = ¹/₂ * 30 * 10
A = 150

The formula for distance traveled d is d=rt, where r is the average speed of the object and t is time traveled. if an object travels 30 meters in 20 seconds, what is its speed?
Answers
Answer:
1.5 meters per second.
Step-by-step explanation:
Distance formula:
d = rt
where d = distance, r = average speed and t = time traveled.
They told us that an object travels 30 meters in 20 seconds.
So we can say d = 30 and t = 20
if you put these values back into the distance formula you get:
d = rt
30 = r times 20
30 = 20 r
So now we want to find what "r" (average speed) is.
Divide both sides by 20.
20 r = 30
r = = 1.5 meters per second.

H2+2h-120
The first 2 (one after H) is square
Answers
Answer:
(h + 12)(h - 10)
Step-by-step explanation:
Assuming you require to factor the expression
Given
h² + 2h - 120
Consider the factors of the constant term (- 120) which sum to give the coefficient of the h- term (+ 2)
The factors are + 12 and - 10 , since
12 × - 10 = - 120 and 12 - 10 = + 2 , thus
h² + 2h - 120 = (h + 12)(h - 10) ← in factored form
See steps
Step by Step Solution:

Reformatting the input :
Changes made to your input should not affect the solution:

STEP

:
Trying to factor by splitting the middle term
1.1 Factoring h2+2h-120
The first term is, h2 its coefficient is 1 .
The middle term is, +2h its coefficient is 2 .
The last term, "the constant", is -120
Step-1 : Multiply the coefficient of the first term by the constant 1 • -120 = -120
Step-2 : Find two factors of -120 whose sum equals the coefficient of the middle term, which is 2 .
-120 + 1 = -119
-60 + 2 = -58
-40 + 3 = -37
-30 + 4 = -26
-24 + 5 = -19
-20 + 6 = -14
-15 + 8 = -7
-12 + 10 = -2
-10 + 12 = 2 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and 12
h2 - 10h + 12h - 120
Step-4 : Add up the first 2 terms, pulling out like factors :
h • (h-10)
Add up the last 2 terms, pulling out common factors :
12 • (h-10)
Step-5 : Add up the four terms of step 4 :
(h+12) • (h-10)
Which is the desired factorization
Final result :
(h + 12) • (h - 10)

Answer:
x=12
Step-by-step explanation:
Because the angles labeled 5x and 4x+12 ate opposite exterior angles, they are congruent. This means that we can set up the following equation:
5x=4x+12
Subtracting 4x from both sides, we have:
X=12
Answer:
x = 12
Step-by-step explanation:
When two parallel lines are intersected by a transversal, the alternate exterior angles are congruent.
5x = 4x + 12
Subtract 4x from both sides,
5x - 4x = 4x - 4x + 12
x = 12

Emilio is pickling tomatillos with his grandfather. The tomatillos are approximately
spheres with a diameter of 6 cm. The pickling jar they are using has a diameter of
8 cm and a height of 21 cm. The jar can hold 3 tomatillos.
Answers
The jar can hold a total of three tomatoes at a time.
What is volume?
Volume is the amount of space occupied by a three dimensional shape or object.
The tomatoes is spherical with a diameter of 6 cm (radius = 6/2 = 3cm), hence:
Volume of tomatoes = (4/3) * π * radius³ = (4/3) * π * 4³ = 268 cm³
The jar is cylinder with diameter of 8 cm (radius = 8/2 = 4) and a height of 21 cm, hence:
Volume of jar = π * radius² * height = π * 4² * 21 = 1055.6 cm³
Amount of tomatoes that can be contained in jar = 1055.6 cm³ / 268 cm³ = 3.9
The jar can hold a total of three tomatoes at a time.
