Mr. R's kindergarten class has 22 students. There are 2 more girls than boys in his class. How many boys are there?
let x=
let y=
Answers
Answer:
13
Step-by-step explanation:
If we want to find out if there are an equal amount of boys and girls, then we do 22/2 which is 11. BUT, it says there are two more girls than boys. So...
11+2 since there are two more boys than girls. 11+2=13 girls.

Work Shown:
The given values are
sin(u) = -12/13cos(v) = -8/17Through the Pythagorean trig identity, we can find
cos(u) = -5/13sin(v) = -15/17I'm skipping these steps, but let me know if you need me to go over them.
Since u and v are in quadrant 3, this means both sine and cosine are negative here
Using those four items, we can then say the following:
cos(v-u) = cos(v)cos(u) + sin(v)sin(u)
cos(v-u) = (-8/17)*(-5/13) + (-15/17)*(-12/13)
cos(v-u) = 40/221 + 180/221
cos(v-u) = (40 + 180)/221
cos(v-u) = 220/221
This is reduced as much as possible because the GCF of n and n+1 is always 1.
You and some friends go to a book fair where booths are set out in rows. You
buy drinks at the refreshment stand and then walk 8 rows north and 2 rows
east to the science fiction booth. Then you walk 1 row south and 2 rows west
to the children's book booth. Where is the children's book booth in relation to
the refreshment stand?
Answers
Answer:
7 rows north of refreshment stand
Step-by-step explanation:
8 rows north and then 2 rows east followed by 1 row south and then 2 rows west will put you directly north of the refreshment stand but since you have traveled one row south, it will be 8-1 = 7 rows north of the refreshment stand

Find the HCF and LCM of 160 and 252 by prime factorisation method and verify that HCF x LCM = Product of the two given numbers.
Answers
Answer:
HCF=4
LCM=10080
HCF x LCM = Product of the two given numbers is verified because 403200=40320
Step-by-step explanation:
HCF of 160 and 252
HCF is the product of common prime factors
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
HCF= 2x2
HCF=4
40 and 63 doesn't come in any other table together so,
HCF= 2 x 2 = 4
Now, finding LCM of 160 and 252
LCM is the product of all factors of both numbers, while if any factor is common, it is considered once.
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
In the given factors 2x2 is common so, it is considered once.
LCM= 2x2x2x2x2x3x5x7
LCM= 10080
Now, checking:
HCF x LCM = Product of the two given numbers.
4x10080=160x252
403200=40320
So, It is verified that HCF x LCM = Product of the two given numbers.

Natalia earns a base salary of $210 each week as a waitress. She usually makes an additional 15% in tips on all orders. Natalia has set a goal to make $1,000 each week. What inequality can she use to calculate x , the total dollar amount of orders needed for her to meet her goal?
Answers
Answer:
The inequality that she can use to calculate x, the total dollar amount of orders needed for her to meet her goal is: 210+0.15x≥1,000.
Step-by-step explanation:
The amount that Natalie makes each week is the result of adding up the base salary she earns plus the result of multiplying the dollar amount of orders for 15% and this result should be greater than or equal to $1,000, which would be:
210+0.15x≥1,000
Now, you can solve for x:
x≥(1,000-210)/0.15
x≥5,267
According to this, the answer is that the inequality that she can use to calculate x, the total dollar amount of orders needed for her to meet her goal is: 210+0.15x≥1,000.

I I 2x+1 I +2 I >1, step by step solution (I I is absolute value)
Answers
The absolute value of x in the inequality I 2x+1 I +2 I >1 showing the step by step solution is x > 2
What is absolute value?The absolute value of a real number x can be defined as the non-negative value of x without regard or consideration to its sign.
It is also known as the modulus of a number.
It is sometimes described as the magnitude of a real number regardless of its sign.
It is important to note that the absolute value must take a positive sign
Given the expression;
I I 2x+1 I +2 I > 1
expand the modulus value
2x + 1 + 2 > 1
collect like terms
2x > 1 + 1 + 2
Add like terms
2x > 4
Make 'x' the subject
x > 4/ 2
x > 2
Thus, the absolute value of x is x > 2

so what we can gather form the diagram given is that all the angles there will add up to 360°.
we can see that they have given one of the angles as 90° as indicated by the little square. so the first step to find x, we need to subtract 90 from 360.
360-90=270
now, we can form an equation to find x. we need to add the other two angles (x, 3x) and then make them equal to 270°.
3x+x=270
add like terms
4x=270
divide by 4
x=67.5°
