sally and belvedere are collecting shirt with a ratio of 4:10. if they collected 462 shirts altogether, how many shirts did sally collect?
Answer:
132
Step-by-step explanation:
the ratio for saly is 4 out of 14. so 4/14 is 0.28571429. and if you multiply that by the total collected shirts which is 462, you get 132 :)))

hi i just need some points rq tyStep-by-step explanation:
Simplify the following trigonometric expression. cosθtan²θcotθ
This question requires the understanding of trigonometric identities. I'll list the ones that are needed to answer this question:
cotθ = 1 / tanθ
tanθ = sinθ / cosθ
Look at the latter identity. We can rewrite it as such:
tanθ * cosθ = sinθ
We are given the expression:
cosθ * tan²θ * cotθ
Referring to the first trigonometric identity above, substitute cotθ:
cosθ * tan²θ * (1 / tanθ)
Multiply tan²θ and the fraction:
cosθ * (tan²θ / tanθ)
cosθ * tanθ
Refer to the second trigonometric identity:
cosθ * tanθ
sinθ
cosθ * tan²θ * cotθ = sinθ
If you have any questions about how I got to the answer, feel free to ask

At a movie theater, a large popcorn cost $8.00 and small drinks cost $3.75 each. If you
buy d drinks and a large popcorn, what expression would represent your bill?
Answer:
large popcorn: $8
small drink: $3.75
= $8 + $3.75
= $11.75
Answer:
$11.75d
Step-by-step explanation:
add 8.00 and 3.75
you get 11.75 since U don't know how much it is for the drink, then U put d 11.75 so when U find d, you'll know that U can add it with your sum.

2. You weigh six packages and find the weights to be 29, 19, 69, 24, 64,
and 59 ounces. If you include a package that weighs 219 ounces, which
will increase more, the median or the mean?
Answer:
mean
Step-by-step explanation:
mean of six packages = (29+19+69+24+64+59)/6 = 44 ounces
Median of these six packages (19,24,29,59,64,69) = (29+59)/2 = 88/2= 44 ounces
Now, if we includes a package that weighs 219 ounces
The new mean = (29+19+69+24+64+59+219)/7 = 69
New median (19,24,29,59,64,69, 219) = 59
Hence, we say that the mean increases more than the median

a triangle has a 40° angle, a 120° angle and a side 2.5 centimeters in length. which of the following statements are true about the triangle?
Answer:
C
Step-by-step explanation:
A triangle is 180 degrees so 120+40 is 160
180-160=20
James has a sidewalk that runs through his flower garden. He needs to put more mulch in the flower garden. If one bag of mulch covers 4 square yards, how many bags of mulch will he need?
Answer:
See Explanation
Step-by-step explanation:
Given
The given proportion can be represented as:
[tex]1\ bag = 4yd^2[/tex]
Required
The additional number of mulch needed
The question has incomplete details, as the amount of mulch he has applied and the area of the flower garden are not given.
So, I will make some assumptions to solve this question.
Let the area of his flower garden be x.
So, we have:
[tex]1\ bag = 4yd^2[/tex]
[tex]y = x\ yd^2[/tex]
Cross multiply
[tex]4yd^2 * y = xyd^2 * 1\ bag[/tex]
Make y the subject
[tex]y = \frac{x\ yd^2 * 1\ bag}{4yd^2}[/tex]
[tex]y = \frac{x* 1\ bag}{4}[/tex]
[tex]y = \frac{x}{4}\ bag[/tex] --- This represents the total amount of mulch required for the flower garden
--------------------------------------------------------------------------------------------------------
Assumptions
Assume that [tex]x = 16[/tex],
So, we have:
[tex]y = \frac{x}{4}\ bag[/tex]
[tex]y = \frac{16}{4}[/tex]
[tex]y = 4[/tex]
i.e 4 bags are needed.
Assume he has applied 2 bags already.
The number of bags needed to apply will be:
[tex]y - 2[/tex]
[tex]y - 2 = 4 - 2[/tex]
[tex]y - 2 = 2[/tex]
2 more bags needed

Find the surface area
Answer:
rectangular prism = cuboid
total surface area of a cuboid (tsa) = 2(lb+bh+hl)
l=length = 3cm
b=breadth = 6cm
h=height = 5cm
tsa = 2( 3*6 + 6*5 + 5*3 )
2( 18 + 30 + 15 )
2 * 63
= 126 [tex]cm^{2}[/tex]

If DE is the midsegment of ABC what is the value of x AND y?
Answer:
3.) x = 4.5
4.) y = 7
Step-by-step explanation:
3 is an easier one than 4. By the triangle midsegment theorem, the midsegment of a triangle will be half of the base if it is parallel to it. AB is our base, so the equation is like this!
[tex]AB = 2(ED)\\9=2(ED)\\4.5=ED[/tex]
Now for 4, it actually is pretty easy. By the same triangle midsegment theorem, we automatically know that EC and EA are congruent, and CD and DB are also congruent. Meaning y equals 7.
But another way we can determine this (the long, kinda unecessary, but useful way) is through examining the relationship that triangles ABC and EDC have! We know that they are similar triangles by SAS or AA. Meaning, their equation looks something like this...
[tex]4.5(7+y) = 9y\\31.5 + 4.5y = 9y\\31.5=4.5y\\7=y[/tex]
Like I said earlier, 7 is equal to y, but I figured I'd prove it so we are on the same page. Nothing wrong with double-checking ;)

Resuelva y responda a la pregunta: Andrés es mayor que su hermano Alex. Dentro de 3 años, la edad de Alex será la edad que tiene ahora Andrés y, dentro 9 años, la edad de Andrés será el doble de la edad que Alex tiene ahora. ¿Qué edades tienen los hermanos?
Answer:
Andrés tiene 15 años y Alex tiene 12 años.
Step-by-step explanation:
Como el enunciado dice que dentro de 3 años, la edad de Alex será la edad que tiene ahora Andrés puedes escribir una ecuación que indique que la edad de Andrés es igual a la edad de Alex más 3:
x=y+3, donde:
x es la edad de Andrés
y es la edad de Alex
Además, como se indica que dentro 9 años, la edad de Andrés será el doble de la edad que Alex tiene ahora puedes escribir una ecuación que indique que la edad de Andrés más 9 es igual a dos veces la edad de Alex:
x+9=2y
Ahora puedes reemplazar x=y+3 en x+9=2y y despejar y:
y+3+9=2y
12=2y-y
y=12
Finalmente, puedes reemplazar el valor de y en x=y+3 para encontrar el valor de x:
x=y+3
x=12+3
x=15
De acuerdo a esto, la respuesta es que Andrés tiene 15 años y Alex tiene 12 años.

Answer:
10.29 (rounded = 10.30)
Step-by-step explanation:
X = a^2 + b^2 = c^2
X = 9^2 + 5^2 = c^2
X = (81) + (25) = c^2
X = 106 = c^2
X = √106 = c^2
X = 10.295630141 = c^2
X = 10.03 = c^2 (10.03 is 10.295630141 rounded to the nearest tenth)

EFGH is a parallelogram. Find m
Answer:
70°
Step-by-step explanation:
Sum of angles in a parallelogram is 360°
Opposite angles are equal
2(16x - 2) + 2(8x + 14) = 360°
32x - 4 + 16x + 28 = 360°
32x + 16x + 28 - 4 = 360°
48x + 24 = 360°
48x = 360 - 24
48x = 336
x = 7
m< E = 8x + 14
Substitute for x
= 8(7) + 14
= 56 + 14
= 70°
