I don't know what's the ten but anyway, "Roberta bought 9/10 pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5-pound bags can Roberta fill? Does she have any left over?" what is the other answer?
Answer:
She can put fill 2 “2/5 pound bags” and will have 1/5 pounds of raisins remaining.
Step-by-step explanation:
First we change the 2/5 into common denominators by multiplying by 2 and we go from 2/5–>4/10. Now that we have this we can see how many times 4 goes into 9 which is 2 so we know that she can fill 2 “2/5 pound bags.” But 4/10x2=8/10 and since we have 9/10 pounds of raisins we subtract 8/10 from 9/10 to get a difference of 1/10. So we have 1/10 pounds of raisins remaining and she can fill 2 full bags of “2/5 pound bags.”
An experiment consists of tossing a die and then flipping a coin once if the number on the die is even. If the number on the die is odd, the coin is flipped twice. Using the notation 4HH, for example, to denote the outcome that the die comes up 4 and then the coin comes up heads, and 3HTHT to denote the outcome that the die comes up 3 followed by a head and then a tail on the coin, construct a tree diagram to show the 18 elements of the sample space SS.
For the sample space SS
(a) list the elements corresponding to the event AA that a number less than 3 occurs on the die;
(b) list the elements corresponding to the event BB that two tails occur;
(c) list the elements corresponding to the event A′A ′;
(d) list the elements corresponding to the event A′∩BA ′ ∩B;
(e) list the elements corresponding to the event A∪BA∪B.
Answer:
Kindly check attached picture for sample space.
Step-by-step explanation:
Sample space, S
S = {1HH, 1HT, 1TT, 1TH, 2H, 2T, 3HH, 3HT, 3TT, 3TH, 4H, 4T, 5HH, 5HT, 5TH, 5TT, 6H, 6T}
The tree diagram for all 18 elements in the sample space can be found in the picture attached below :

In rhombus QRST diagonals RT and QS are drawn. If m
then which of the following is the measure of
a 76
b 90
C 38
d 48
HELP ME PLEASE !!! thank you
Answer:
<STR = 38degrees
Step-by-step explanation:
Find the diagram attached
Complete Question:
In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?
Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y
y+y+104 = 180
2y = 180-104
2y = 76
y = 38degrees
Since <STR = y, hence the measure of <STR = 38degrees
45% of the population of a city are men
and 15% are children. If the number of
women is 64,400, find the number of
children.
Answer:
[tex]\boxed{\textsf{ The number of children is \textbf{24150}.}}[/tex]
Step-by-step explanation:
Given that the 45% of the population of a city are men and 15% are children . The number of women is 64,400 . And we need to find the number of children . Here ,
[tex]\sf\implies Percentage_{(men)}= 45/% .\\\\\sf\implies Percentage_{(children)}= 15\% . [/tex]
So the percentage of women will be equal to [ 100 - ( 45 -15) ]% = [ 100 - 60 ]% = 40% .
So let us take the total number of people be x . So ,
[tex]\purple{\bigstar}\underline{\underline{\boldsymbol{ According\ to \ Question :- }}}[/tex]
[tex]\sf\implies 40\% \ of \ x \ = \ 64,400 \\\\\sf\implies \dfrac{40x}{100}= 64,400 \\\\\sf\implies x =\dfrac{64,400\times 100}{40}\\\\\sf\implies \boxed{\pink{\sf x = 161,000 }}[/tex]
[tex]\rule{200}2[/tex]
The percentage of children = 15% :-
[tex]\sf\implies Number_{(children)}= 15\% \ of 161,000\\\\\sf\implies Number_{(children)}= \dfrac{15}{100}\times 161,000 \\\\\sf\implies \boxed{\pink{\frak {Number_{(children)}= 24150 }}}[/tex]

Quick help!!Also number 17!
Answer:
16. 29 and 30
17. C. 30 D. 31
Step-by-step explanation:
16. Given the inequality c ≤ $30, which is used to represent the situation, it implies that possible value of c must be equal to $30 or less than $30.
Two possible solutions form the options given would be:
29 and 30.
29 is less than 30, and 30 is equal to 30.
17. The inequality given is b ≥ 30.
This implies that possible solutions will be equal to 30 or greater than 30. It cannot be less than 30.
The solutions that apply would be:
30 (this is equal to 30) and 31 (this is greater than 30).
The remaining options don't satisfy or make the inequality statement true.

Which answer is an equation in point-slope form for the given point and slope?
Point (1, 9), Slope: 5
(A) y - 9 = 5(x + 1)
(B) y+9 -5(x - 1)
(C) y-9=5(x - 1)
(D) y-1-5(x +9)
Answer:
Step-by-step explanation:
Point-slope equation for line of slope m that passes through (x₀,y₀):
y-y₀ = m(x-x₀)
In your case, m=5 and (x₀,y₀)=(1,9):
y-9 = 5(x-1)

Find the values of x and y in the diagram.
Answer:
x = 3
y = 10
Step-by-step explanation:
In triangle KLN, measure of all angles are equal.
Therefore, it is an equilateral triangle.
All sides of an equilateral triangle are equal.
So,
y - 4 = 6
y = 6 + 4
y = 10
In triangle LMN, measures of angles M and N are equal, Therefore,
LM = LN
x + 3 = y - 4
x + 3 = 10 - 4
x + 3 = 6
x = 6 - 3
x = 3

Step-by-step explanation:
Corey spies a bald eagle in a tall tree. He estimates the height of the tree to be 60 feet and the angle of elevation to the bird from where he stands to be 64°. The leaves on the tree make it difficult for Corey to watch the bird, so he takes many steps away from the tree to get a better view. He now estimates his angle of elevation to be 37°.
How many feet did Corey step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.
Answer:
Corey stepped back 59.71 feet
Step-by-step explanation:
Right Triangles
They are a special type of triangle where one of its internal angles is 90°. The basic trigonometric equations stand in this type of triangles. If x is the adjacent leg of a given angle , and y is the opposite leg to the same angle, then :
[tex]tan0= \frac{y}{x}[/tex]
We can solve for x to get
[tex]x = \frac{y}{tan0}[/tex]
Corey estimates the height of the tree to be 80 feet. This means we know y=80 and . Let's find the horizontal distance at which Corey is looking at the bald eagle:
[tex]x1 =\frac{80}{tan68}[/tex]
[tex]x1 = 32.32 feet[/tex]
Now Corey moves back to watch the very same tree at an elevation angle of 41°. The tree has the same height, so
[tex]x2 =\frac{80}{tan41}[/tex]
[tex]x2= 93.03 feet[/tex]
Now we can know the distance Corey walked back by subtracting both distances
correy stepped back 59.71 feet
The number of feets corey will step back to gain a better view of the bird is 54.72feet.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.
In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slant side is called hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.
here, we have,
Given that;
The height of tree=80feet
The angle of elevation to the bird from him=68°.
His estimated angle of elevation = 41°
Now,
Use trig to find x
then use trig to find x+y
Then subtract to find y
tan41°= 80ft/(80ft/tan65 + y)
80/tan65 + y = 80/tan41
y= 80/tan41 - 80/tan65
y= 54.72ft
Therefore, by trigonometry the answer will be 54.72feet.

Restaurants often slip takeout menus under Rosa's apartment
door. So far, Rosa has collected 15 menus, including 5 for
Indian food. Considering this data, how many of the next 18
menus slipped under Rosa's door should you expect to be
from Indian restaurants?
Answer:
6.
Step-by-step explanation:
Since restaurants often slip takeout menus under Rosa's apartment door, and so far, Rosa has collected 15 menus, including 5 for Indian food, to determine, considering this data, how many of the next 18 menus slipped under Rosa's door should be expected to be from Indian restaurants the following calculation and logical reasoning must be performed:
5/15 = 0.333333
Thus, 1/3 of the restaurant ads correspond to Indian restaurants. Therefore, since 18 x 1/3 equals 6, the number of Indian restaurant menus that could be expected to be slid under Rosa's door is 6.

Answer:
x= −1/5y + 2/5
Step-by-step explanation:
Let's solve for x.
y=−5x+2
Step 1: Flip the equation.
−5x+2=y
Step 2: Add -2 to both sides.
−5x+2+−2=y+−2
−5x=y−2
Step 3: Divide both sides by -5.
Answer:
x= -1/5y + 2/5
not 100% sure if ur trying to solve for x or just graph that equation but hopefully this helped lol :)
