Step-by-step explanation:
If a =(9,18) and b=(1,12) what is the length of ab
Answer:
AB = 10
Step-by-step explanation:
Use the distance formula: √(12 - 18)^2 + (1 - 9)^2
√36 + 64
10
Answer:
10 units
Step-by-step explanation:
Use the distance formula. Substitute the values, (1-9)²+(12-18)²=100. The square root of 100 is 10.
how would you change x + 3y = 18 -3x - 12y = -75 to eliminate x
Answer:
Multiply the equation by 3 making positive 3X which will cancel out with negative 3X

Answer:
Step-by-step explanation:
(i) Area of ABCD = (base1+base2)*height/2
= (6+12)*4/2 = 36 cm2
(ii) Volume = Area of ABCD * length = 36 * 25 = 900 cm3
(iii) Total SA = Area of ABCD *2 + 25*5*2 + 6*25 + 12*25
= 72 + 250 + 150 + 300

a Fair coin is tossed 4 times. What is the probability of not getting all heads?
Answer:
15/16
Step-by-step explanation:
The probability of not getting all heads is
1 - P(all heads)
P (all heads) =P(heads) * P(heads)* P(heads) * P(heads)
1/2* 1/2 * 1/2 * 1/2 = 1/16
1 - 1//16 = 15/16

Suppose you are planning a ward party. Last year, there was a similar activity and 150 people attended. If the ward has grown by 9%, how many people do you expect will attend this year? (Round your answer to the nearest whole number.)
Answer:
164 people
Step-by-step explanation:
100% represents the 150 people who attended last year.
this year , there is an increase of 9% , which will make the total percentage to be 109%.
if ; 100% = 150 people
109% = ?

In a group of Year 9 students, the ratio of boys to girls is 9 : 7. There are 4 more boys than girls in this group. How many students are in this group altogether?
Answer: 32
Step-by-step explanation:
There are 18 boys and 14 girls (4 more boys than girls. 32 students total.
If the ratio of boys to girls is 9 : 7, there are 32 students in this Year 9 group altogether.
Let's denote the number of boys as "9x" and the number of girls as "7x" since the ratio of boys to girls is 9:7. We are also given that there are 4 more boys than girls, so we can set up an equation:
Number of boys = Number of girls + 4
9x = 7x + 4
Now, we can solve for "x":
9x - 7x = 4
2x = 4
x = 2
Now that we have the value of "x," we can find the number of boys and girls:
Number of boys = 9x = 9 * 2 = 18
Number of girls = 7x = 7 * 2 = 14
Finally, to find the total number of students in the group, we add the number of boys and girls:
Total number of students = 18 (boys) + 14 (girls) = 32.
The ratio of boys to girls is 9:7, and there are 4 more boys than girls.

Diana works at a clothing store. She sold 1/3 of the total shirts on Tuesday and 5/12of the total number of blue shirts on Wednesday. What fraction of blue shirts did she sell on Tuesday and Wednesday?
Answer:
The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
She sold:
1/3 on Tuesday.
5/12 on Wednesday.
What fraction of blue shirts did she sell on Tuesday and Wednesday?
Sum of fractions.
The lesser common multiplier between 3 and 12, which is 12.
So
[tex]\frac{1}{3} + \frac{5}{12} = \frac{\frac{12*1}{3} + \frac{12*5}{12}}{12} = \frac{4 + 5}{12} = \frac{9}{12} = \frac{3}{4}[/tex]
The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]
what is the circumference of a circle witha radius of 4 in
25.12 in or 8π
Step-by-step explanation:
Since you didn't specify whether or not to leave pi or to make it be 3.14, I did both.
The formula for the circumference of a circle is...
[tex]C=2\pi r[/tex]
So...
[tex]C=2*3.14*4[/tex]
C = 25.12 in
If you want to leave pi...
[tex]C=2*\pi *4[/tex]
C = 8π
In ΔLMN, the measure of ∠N=90°, ML = 97, NM = 65, and LN = 72. What ratio represents the tangent of ∠L?
Answer:
tan ∠L = 65/72
Step-by-step explanation:
The tangent ratio is:
tan of angle x = opposite/adjacent
Looking from the perspective of angle L, find the opposite side.
This side is MN, measuring 65 units.
opposite = 65
Now let's find the adjacent side.
This side is LN, measuring 72 units.
adjacent = 72
Therefore, the tangent ratio of angle L is 65/72.
Answer:
65/72

Answer:
x = [tex]\frac{ab}{c+a}[/tex]
Step-by-step explanation:
a(b-x) = cx
ab - ax = cx
ab = cx + ax
ab = x (c + a)
divide both sides by (c + a) for x to stand alone
x = ab/ c + a
What is the x-value that solves the system 4x-y=21 and y=3x-7
Answer:
x=14
Step-by-step explanation:
4x-y=21
y=3x-7
Substitute the second equation in for y in the first
4x - (3x-7) = 21
Distribute the minus sign
4x -3x +7 = 21
x +7 = 21
Subtract 7 from each side
x+7-7=21-7
x=14
Answer: x=14 is right answer
4x-y=21 =
Slope = 4
x-intercept = 21/4 = 5.25000
y-intercept = 21/-1 = -21.00000
y=3x-7 =
Slope = 6.000/2.000 = 3.000
x-intercept = 7/3 = 2.33333

Joaquin used 1-3/6 cups of apple juice and 1-4/6 cups of orange juice in a recipe for punch. How much juice did Joaquin use?Solve this problem any way you choose.
Answer:
The answer is 3 and 1/6 cups.
Step-by-step explanation:
If Joaquin used 1 and 3/6 cups of apple juice and 1 and 4/6 cups of orange juice for the punch, there is a total of 2 cups and the fractions can be added as their denominators are the same.
3/6 + 4/6 = 7/6 cups
So the total juice in the punch is 3 and 1/6 cups.
