there 6 more girls than boys in a class there 44 students in the class in all how many boys are there
Answer: 28 boys and 16 girls
Step-by-step explanation: Divide 44 by 2 to get 22 subtract 22 by 6 to get the girls and add 6 to 22 to get the boys.
Answer:
44% of the students of a class are girls. If the number of girls is 6 less than the number of boys, how many students are there in the class?
let x be the number of boys, so (x - 6) will be number of girls.
total number of students will be boys plus girls : x + (x - 6) = 2x - 6
now 44% are girls which come from formula no. of girls divide by total students into 100: (x - 6)/(2x-6)*100 = 44
by solving we get x = 28 (where x is number of boys)
now x - 6 = 28–6 = 22 (number of girls)
add both we get total number of students = 28 + 22 = 50
Answer = 50

[tex] \color{plum}\bold{(C)} [/tex] Diameter of circle P is the same length as the radius of circle Q.
○=> Steps to derive correct option :Given :
Diameter of circle P = 26 cm
Radius of circle P :
[tex] =\tt \frac{diameter}{2} [/tex]
[tex] = \tt \frac{26}{2} [/tex]
[tex]\color{plum} = \tt13 \: cm[/tex]
Thus, radius of circle P = 13 cm
Diameter of circle Q = 52 cm
Radius of circle Q :
[tex] = \tt \frac{diameter}{2} [/tex]
[tex] =\tt \frac{52}{2} [/tex]
[tex] \color{plum}= \tt26 \: cm[/tex]
Thus, radius of circle Q = 26 cm
Radius of circle R = 52 cm
Diameter of circle R :
[tex] =\tt radius \times 2[/tex]
[tex] =\tt 52 \times 2[/tex]
[tex]\color{plum} = \tt104 \: cm[/tex]
Thus, the diameter of circle R = 104 cm
☆ Conclusion :
▪︎Diameter of circle P is the same length as the radius of circle Q.
Therefore, the correct option is (C) Diameter of circle P is the same length as the radius of circle Q.
divide 220 in the ratio 3:8
Answer:
500/(7+3)=50; 3*50=150, 7*50=350. 150:350=3:7
Step-by-step explanation:
o Ayan sinolve kayan geh pa follow po
220 is divided in the ratio 3:8 as 60 and 160 respectively.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The given ratio is 3:8 and the number is 220.
Here, 3+8=11
Now, 3/11 ×220
= 3×20
= 60
8/11 ×220
= 8×20
= 160
Therefore, 220 is divided in the ratio 3:8 as 60 and 160 respectively.

WHAT WOULD THIS BEE!
Answer:
98
Step-by-step explanation:
It would be the same amount because when the lines are parallel, the corresponding angles will also be the same.
We can tell the difference between the two types of angles (Supplementary and complementary) 98 and 82 would be the two types of angles.
So, the angle measure would be 98.

29%
79%
21%
31%
Which equation can be solved
Answer: Choice B) 2x-60 = 180
===========================================================
Explanation:
A bit of the question got cut off. I'm assuming the full question reads "In this diagram, the measure of angle RQS is 60 degrees less than the measure of angle PQS"
The portion underlined is the part cut off where I'm making the assumption. If that assumption is correct, then we have
angle PQS = xangle RQS = x-60Those two adjacent angles form a straight line of 180 degrees
(anglePQS) + (angleRQS) = 180
(x) + (x-60) = 180
2x-60 = 180
which points to choice B as the answer.
Answer:
Step-by-step explanation:
∠RQS = x - 60°
∠RQS = 180° - x
x - 60° = 180° - x
2x - 60° = 180°

The volume of a cylinder is 63 pi cm^3 . If the radius is 3cm, what is the height of the cylinder?
A. 3.5 cm
B. 21 cm
C. 10.5 cm
D. 7 cm
will give brainliest
Answer:
Step-by-step explanation:
volume = πr²h = π·3²h = 63π
h = 7 cm
The height of the given cylinder is 7 cm. Therefore, option D is the correct answer.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, the volume of a cylinder is 63π cm³ and the radius is 3 cm.
We know that, the formula to find the volume of a cylinder is πr²h.
Now, πr²h=63π
π×3²×h=63π
h= 7 cm
Therefore, option D is the correct answer.

An angle measures 106.4° less than the measure of its supplementary angle. What is the measure of each angle
Answer:
The two supplementary angles are 10 and 170 degrees.
Step-by-step explanation:
Two angles are supplementary when that add up to 180 degrees. In this case, we are given that one of the two angles is 160 degrees more than the other. We can construct the following equation. x + ( x + 160 ) = 180 x
represents the degree measure of the smaller angle. Now, all we need to do is solve the equation for x. 2 x + 160 = 180 2 x = 20 x = 10
Now that we have the value of the smaller angle, we can easily solve for the larger angle. We are told that it is 160 degrees larger than the other one.
10 + 160 = 170. Therefore, the two supplementary angles are 10 and 170 degrees.
Amy ran 0.75 kilometers each day for 3 weeks. How many meters did she run over the 3 weeks?
Answer:
15,750 meters
Step-by-step explanation:
There are 1000 meters in a kilometer
.75 of a kilometer is 750 meters
There are 7 days in a week, 7x3 is 21.
750 x 21 = 15,750
Answer:
15750meters
Step-by-step explanation:
3 weeks=3x7
=21days
1day=0.75km
21days=21x 0.75
=15.75km
1km=1000m
15.75km=(1575/100 x 1000)m

What is an equation of the line that passes through the points (-5, 6) and
(7, 6)?
Answer:
y = 6
Step-by-step explanation:
line of an equation: y = mx +c
where c is y-intercept, m is gradient and y and x are the y and x coordinates.
For finding the line of an equation we first find a gradient
gradient = (y2 -y1) / (x2 - x1)
so; (6-6) / (7-(-5)) = 0/12 = 0
next using any pair of coordinates we will find the c (y-intercept)
6= 0 (-5) + c
c = 6
so the equation will be
y = mx + c
(add the values you just found)
y = (0)x + 6 (since anything multiplied by 0 is 0 so we can write its like;)
y = 6

Find a quadratic polynomial with integer coefficients which has x = 2/9, ± SQRT23/9 as its real zeros.
Answer:
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].
Step-by-step explanation:
Statement is incorrectly written. Correct form is described below:
Find a quadratic polynomial with integer coefficients which has the following real zeros: [tex]x = \frac{2}{9}\pm \frac{\sqrt{23}}{9}[/tex].
Let be [tex]r_{1} = \frac{2}{9}+\frac{\sqrt{23}}{9}[/tex] and [tex]r_{2} = \frac{2}{9}-\frac{\sqrt{23}}{9}[/tex] roots of the quadratic function. By Algebra we know that:
[tex]y = (x-r_{1})\cdot (x-r_{2}) = x^{2}-(r_{1}+r_{2})\cdot x +r_{1}\cdot r_{2}[/tex] (1)
Then, the quadratic polynomial is:
[tex]y = x^{2}-\frac{4}{9}\cdot x -\frac{19}{81}[/tex]
[tex]y = 81\cdot x^{2}-36\cdot x -19[/tex]
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].

A right rectangular prism has a volume of
[tex] {6x}^{3} - {3x}^{2} - 45x[/tex]
What are expressions for the length, width, and height?
Answer:
3x, 2x + 5, and x - 3
Step-by-step explanation:
Since the given figure is a 3-dimensional shape, we know that there must be three zeroes.
Our equation is:
6x³ - 3x² - 45x
First, we can factor out an x:
x (6x² - 3x - 45)
From here, we can see that by factoring out a 3:
3x (2x² - x - 15)
Now, after completing the square and factoring:
3x (2x + 5) (x - 3)
These are our three expressions.

Find the solution to the following system of equations using substitution or elimination y=-2x+7 y=3x-8
Answer:
x = 3, y = 1
Step-by-step explanation:
By substitution since y = -2x + 7, substitute that for the 2nd y so
-2x +7 = 3x - 8, so x = 3, then substitute the 3 in any of the equations, so y = -2(3) + 7 is equal to 1
If you use elimination you can subtract the two equations from each other to get rid of the y so
y = -2x + 7
-y = -3x + 8
so 0 = -5x + 15, 5x = 15, x=3
