Answer:
Stem Leaf
2 8
3 4 4
5 0 4
So we need to put all the tens values in the "stem" column and all the ones values in the "leaf" column, sorted from least to greatest.
We have three tens values: 2, 3, and 5. So those are our three stems, in order.
We have to put the second number, the ones value, in the leaf column, least to greatest. So with two values of 34, we need two 4 leaves.

The perimeter of a rectangular yard which has one side that measures twenty-three metres equals 154 m. What are the dimensions of each side of the yard? PLEASE SHOW ME THE FORMULA YOU USE.
Answer: our rectangle is 23 meters of width and is 54 meters long.
Step-by-step explanation:
The perimeter of a rectangle is P = 2*W + 2*L
where W is the width and L is the length.
We know that W = 23m and P = 154m
then:
154m = 2*23m + 2*L
(154m - 2*23m)/2 = L = 54m
So our rectangle is 23 meters of width and is 54 meters long.

4 tan 45° +(2 sin 45°) (6 cos 45°)
Answer:
value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.
Step-by-step explanation:
To solve this question we need to know value of
tan 45° = 1
sin 45° = [tex]1/\sqrt{2}[/tex]
cos 45° = [tex]1/\sqrt{2}[/tex]
we will be using above value sin the given expression as shown
[tex]4 tan 45 +(2 sin 45) (6 cos 45) = 4*1 + (2*1/\sqrt{2} )(6*1/\sqrt{2})\\ = 4 + (2/\sqrt{2}) (6/\sqrt{2})\\= 4 + (2*6)/(\sqrt{2}*\sqrt{2})\\= 4 + (12/2)\\= 4 + 6 = 10[/tex]
Thus, value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.

Please answer correctly !!!!! Will mark brainliest !!!!!!!!!!
Answer:
Exactly one solution
Step-by-step explanation:
4x -2y = 8
2x +y = 2
Multiply the second equation by 2
4x +2y = 4
Add the two equations together
4x -2y = 8
4x +2y = 4
-------------------
8x = 12
x = 12/8
We know there will be one solution
A cylindrical jar’s life has a radius of 4 inches. If the volume is 351.68in^3, approximately what is the height of the jar?
Answer:
7 inches
Step-by-step explanation:
The volume of a cylinder is calculated using
where r =4 inches is the radius and V=351.68 is the volume.
To find the height of the jar, we substitute these values and solve for h.
Divide both sides by 50.24 to get:
h=7 inches
Therefore the height of the jar is 7 inches
The total cost of a pair of shoes and a belt was $71.57. If the price of a pair of shoe was $1.79 less than the belt, what was the price of the pair of shoes?
Answer:
$34.89
Step-by-step explanation:
Here, we want to calculate the price of the pair of shoes.
Let the price of the belt be $x, we know that the price of pair of shoes would be x-1.79
so adding;
x + x-1.79 = 71.57
2x = 71.57 + 1.79
2x = 73.36
x = 73.36/2
x = $36.68
The price of pair of shoes = x-1.79 = 36.68-1.79 = $34.89
Madison has three jobs. This week she earned $124 waitressing, $30 delivering packages, and $46 babysitting. What percent of her money earned this week came from babysitting
Answer:
23%
Step-by-step explanation:
Answer:
23 %
Step-by-step explanation:
The total money earned:
124+ 30+ 46 =200
Percent earned babysitting
money earned babysitting / total * 100%
46/200 * 100 = 23 %
Find the area of a sector with a central angle of 180° and a diameter of 5.6 cm. Round to the nearest tenth.
Answer:
Step-by-step explanation:
Mathematically, the area of a sector can be calculated using the formula below;
area of sector = angle/360 * pi * r^2
From the question, angle = 180
pi= 22/7
r = d/2 = 5.6cm/2 = 2.8 cm
So the area of the sector is as follows;
A = 180/360 * 22/7 * 2.8^2
A = 2 * 22/7 * 2.8^2 = 49.28
which is 49.3 cm^2 to the nearest tenth
Line t is the perpendicular bisector of FG. If line t intersects FG at point H,
which of the following statements must be true?
Check all that apply.
A. Point His the midpoint of FG
B. Line tintersects FG at a right angle
C. FG = FH
D. Line tis perpendicular to FG
E. Line tis parallel to FG
A, B, D are your answers
AP E X
Point H is the midpoint of FG, Line t intersects FG at a right angle and Line t is perpendicular to FG are true statements.
What is Coordinate Geometry?A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
A. Point H is the midpoint of FG: This statement must be true because line t is the perpendicular bisector of FG, which means it passes through the midpoint of FG and intersects FG at a right angle.
Therefore, H is the midpoint of FG.
B. Line t intersects FG at a right angle: This statement must be true because line t is the perpendicular bisector of FG, which means it intersects FG at a right angle.
C. FG = FH: This statement is not necessarily true.
While H is the midpoint of FG, the length of FH depends on the position of point H along line t. It could be greater than, less than, or equal to half the length of FG.
D. Line t is perpendicular to FG
This statement must be true because line t is the perpendicular bisector of FG, which means it is perpendicular to FG.
E. Line t is parallel to FG: This statement is not true. If line t were parallel to FG, it would not intersect FG at all, let alone at a right angle as required for a perpendicular bisector.
Therefore, Point H is the midpoint of FG, Line t intersects FG at a right angle and Line t is perpendicular to FG are true statements.

find the value of x.
please help !!
Answer:
y = 120
Step-by-step explanation:
Interior angles of a triangle add up to 180°
So,
x+87+33 = 180
x + 120 = 180
Subtracting 120 to both sides
x = 180-120
x = 60°
Now
Angles on a straight line also add up to 180°
So,
x+y = 180
60 + y = 180
Subtracting 60 to both sides , we get
y = 180-60
y = 120

A number cube (dice) is rolled and a letter is selected from the word GIRAFFE. What is the compound probability of P ( 4 and F) P(EVEN NUMBER AND VOWEL)
Answer:
P (4 and F) = 1 in 21 or 4.76%
P(EVEN NUMBER AND VOWEL) = 3 in 14 or 21.43%
Step-by-step explanation:
The probability of rolling a four on a die is 1 in 6.
The probability of picking the letter F in the word GIRAFFE is 2 in 7.
Therefore:
[tex]P (4\ and\ F)=P(4)*P(F)\\ P (4\ and\ F)=\frac{1}{6}*\frac{2}{7}\\ P (4\ and\ F)=\frac{1}{21}= 4.76\%[/tex]
The probability of rolling an even number (2, 4 or 6) on a die is 3 in 6.
The probability of picking a vowel (A, E, I) in the word GIRAFFE is 3 in 7.
Therefore:
[tex]P (Even\ and\ Vowel)=P(Even)*P(Vowel)\\ P (Even\ and\ Vowel)=\frac{3}{6}*\frac{3}{7}\\ P (Even\ and\ Vowel)=\frac{3}{14}= 21.43\%[/tex]

Given a square with two vertices of one side located at -5,-3 and -5,12 in square units what is its area
Answer:
225 units squaredStep-by-step explanation:
Lets find the distance (the side length of the square)
D=sqrt((x2-x1)^(2)+(y2-y1)^(2))
plug in the coordinates:
D=sqrt((-5-(-5))^(2)+(12-(-3))^(2))
D=sqrt(0^(2)+15^(2))
D=sqrt(15^(2))
D=15
Area of a square is side length squared
A=s^2
A=15^2
A=225 units squared

Answer:
The value of x is 66
Step-by-step explanation:
Answer:
66°
Step-by-step explanation:
The interior angles of a triangle always sum up to 180°. Looking at the first triangle, we see 48° + 66° + x = 180°, or x = 180° - (48° + 66°) = 66°. This is true because the triangles are congruent.

c=no. of copies
Direct variation can be written as
P=KC
K=constant
P=1 when c=5
1=k*5
1=5k
k=1/5

This recipe makes 3 portions of potato soup.
Richard follows the recipe but wants to make 9 portions.
Complete the amounts of each ingredient that he needs.
Recipe: Serves 3
20 ml oil
30 g onions
400 g potatoes
450 ml milk
Answer:
60 ml oil, 90 g onions, 1200 g potatoes, 1350 ml milk
Step-by-step explanation:
What you need to do here is multiply all of these ingredients by 3, because the recipe serves 3 and he needs to serve 9, and 9/3 = 3. Therefore, he would have to triple the recipe.
I'm really confused about this. Probabilities have always been a pain for me and I really don't understand this
Answer:
A
Step-by-step explanation:
The first thing to notice is the question says it is given that the person is between the ages 23 and 60, so we only care about those people. So then we want to know how likely it would be to pick someone with over 50 messages a month. So what you would do is take the amount of people who are between 23 and 60 and send over 50 text messages, and divide that by the total amount of people 23-60 (since that is the pool of people we have). Doing so we find there is 229 people aged 23-60 which then makes the answer 157/229 or A.

PLEASE HELP!!! GEOMETRY QUESTION
Answer:
Step-by-step explanation:
2y + 100 +6x-10=180(in a cyclic quadrilateral opposite angles are supplementary)
2y+6x+90 =180
2y + 6x = 90
dividing each side by 2
y+3x = 45 ........1
7x+1+2y+74 =180 ( same reason)
7x + 2y =105 ............2
multiplying 1 by 2
2y +6x =90........ 3
subtracting 3 from 2
7x+2y-2y-6x = 105-90
x = 15
substituting x=15 in 1
y+45 =45
y= 0
