E. 35º, 70°
Answers
Answer:
E. 35°, 70°
Step-by-step explanation:
Sum of angles add up to 180° in every triangle.
Step 1: Set up equation
a + 2a + 75 = 180
Step 2: Combine like terms
3a + 75 = 180
Step 3: Subtract 75 on both sides
3a = 105
Step 4: Divide both sides by 3
a = 35
So 1 angle is 35°
Step 5: Plug in a to find last angle
2(35) = 70°

Nora took 10 bottles of water to a picnic. Of these bottles of water, she and her friends opened a certain number of bottles, b. What expression can be used to determine the number of unopened bottles at the end of the picnic?
Answers
Answer:
10 - B = U
Step-by-step explanation:
U stands for the unopened bottles
for example if they opened 3 bottles it would be 10 - 3 = U (unopened bottles)
The value of U is 7 because the 10 bottles of water minus the 3 bottles they opened it would equal 7.
therefore the equation 10 - B = U shows the amount of unopened bottles
Calculate 12 x 15 by changing the numbers into friendlier numbers as we saw in the videos. Show how you work it out – write out your methods using the number keys on your computer here: Please write your response.
Answers
Answer:
The product 12 × 15 in friendlier numbers is (10 + 2) × (10 + 5) = 180
Step-by-step explanation:
The parameter given are;
To 12 × 15 by changing the numbers into friendlier numbers
The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;
12 × 15 = (10 + 2) × (10 + 5)
Which gives;
(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5
From which we have;
10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180
Therefore;
12 × 15 = 180.
6x + 3 (2x) - 7 - 2³ Please include th steps to solving it.
Answers
Answer:
24x-15
Step-by-step explanation:
Let's do this together with a step-by-step explanation!
First we need to make sure we remember that there are appropriate ways on how to solve these. LIKE PEMDAS.
6x + 3 (2x) - 7 - 2³
Let's multiply the 3 and 2x together.
6x + 6x - 7 - 2³
Now let's do the exponent
6x + 6x - 7 - 8
Now let's add everything together! But remember only common variables can be added together.
24x - 15 is the answer.
You can no longer break anything down.
I really hope this helped you!
Answer:
12x - 15
Step-by-step explanation:
so you would have to do the order of operations. so your exponent would be first. so 2×2×2=8.
6x + 3 (2x) -7 + 8
Now you can look at your parentacese which is (2x) so you need to do 3(2x) which gets you 6x.
6x + 6x -7 + 8
So you need to combine like terms.
so starting with the x
6x + 6x = 12x
Now your equation looks like this
12x + -7 +8
now you need to add like terms. (numbers)
-7 -8
so your answer is
12x -15
if the width is 8 less than the length of a rectangle and the perimeter is 48 find the width
Answers
Answer:
Widyh = 8 units
Step-by-step explanation:
Perimeter = 2/width+length)
then:
48 = 2(W+L)
W = L-8
W = Width
L = Length
then:
48 = 2((L-8)+L)
48 = 2(2L88)
48 = 2*2L - 2*8
48 = 4L - 16
48 + 16 = 4L
64 = 4L
L = 64/4
L = 16
W = L-8
W = 16-8
W = 8
Check:
48 = 2(16+8)
48 = 2*24
12, 13, 14, 15, 21, 24, 25, 26, 27, 29, 32, 32, 38, 41, 47. Make a box-and-whisker plot for the data. What is the 5 point summary for this box and whisker plot?
Answers
Answer:
Hence the five point summary is:
i) Minimum = 12
ii) Maximum = 47
iii) Median = 26
iv) First quartile = 15
v) Third quartile = 32
Step-by-step explanation:
The five point summary of a box and whisker plot is the minimum, maximum, median, first quartile and third quartile.
Given the number 12, 13, 14, 15, 21, 24, 25, 26, 27, 29, 32, 32, 38, 41, 47.
The median is the middle number = 26
The first quartile is the median of the numbers to the left of the median. Hence the first quartile is the median of 12, 13, 14, 15, 21, 24, 25
First quartile = 15
The third quartile is the median of the numbers to the right of the median. Hence the third quartile is the median of 27, 29, 32, 32, 38, 41, 47.
Third quartile = 32
The minimum is the lowest number = 12
The maximum is the largest number = 47
The box and whisker plot is attached
Hence the five point summary is:
i) Minimum = 12
ii) Maximum = 47
iii) Median = 26
iv) First quartile = 15
v) Third quartile = 32

can someone show me the answer + how they got there? (x+4)(x-1)
Answers
Answer:
x^2+3x-4
Step-by-step explanation:
x * x - x + 4x - 4
x^2 - x + 4x - 4
x^2 + 3x - 4
=============================================
Explanation:
You can use the FOIL rule to expand out (x+4)(x-1), but here's another way you could do it.
Let y = x+4
This means we replace (x+4) with y to get y(x-1)
Distribute the y term through to get yx-y which can be written as x(y) - 1(y)
After this, replace y with x+4 getting x(x+4)-1(x+4)
Distribute a second time and simplify like so
x(x+4)-1(x+4)
x^2+4x-1x-4
x^2+3x-4

Step-by-step explanation:
- 0.75p - 2 =0.25p add .75p on both sides
-2 = p That's the same thing at p = -2
Answer:
p = -2
Step-by-step explanation:
-0.75p - 2 = 0.25p Subtract 0.25p from both sides
-1p - 2 = 0 Add 2 to both sides
-1p = 2 Divide by -1 on both sides
p = -2
On a vertical line segment, point A is located at 50. Point B is located at 104. Point P is a point that divides segment AB in a ratio of 1:5 from A to B. Where is point P located?
Answers
Answer:
Step-by-step explanation:
Let the initial point on the line segment be O. If point A is located at 50 and point B is located at 104, then OA = 50 and OB = 104. Using the vector notation;
AO+OB = AB
(-OA)+OB = AB
-50+104 = AB
AB = 54
If point P divides the segment AB in a ratio 1:5, them AP:PB = 1:5
AP = 54/6
AP = 9
PB = 54-9
PB = 45
Hence the point P is located at 9 units from A and 45 units from B
