Mrs. Flores is sending packages to two grandchildren.
The package for Santiago weighs 7.82 pounds, and the package for Sofia weighs 7.28 pounds.
Select words from the drop‐down menus to explain how Mrs.
Flores can use place value to find which package weighs more.
Mrs. Flores can compare each digit of the decimals starting from the
left or right?
.
The
ones
place of each weight is 7, so she should compare the
tenths
places.
The package for
Santiago
has an 8 in the
tenths
place, and the package for
Sophia
has a 2 in the same place.
So, the package for
Santiago
weighs more.

Can someone help me on this
Answer:
Step-by-step explanation:
14y-1=11y+17 subtract 11y from both sides
3y-1=17 add 1 to both sides
3y=18, divide both sides by 3
y=6
Since DG=EF
EF=9y+4 and using y=6
EF=9(6)+4
EF=54+4
EF=58
How to solve 4 x = 16
Answer:
x=4
Step-by-step explanation:
First we Divide both sides by 4 so we can just get x
For example
4x=16
x=4 We divided both sides by 4 because we need to get x and the reason why we also divided 16 by 4 is because what you do to one side you do to the other to keep the values consistent

A standard number cube,numbers 1 through 6 on each side,is rolled 3 times.what is the probability of rolling a 2 on all three rolls?
Answer: 1/216
Step-by-step explanation:
First roll has 1/6 probability of landing on 2. Second roll has 1/6 probability of landing on 2. Third roll has 1/6 probability of landing on 2.
So you multiply 1/6*1/6*1/6 = 1/216
. Bryon competes on the school debate team. He won 0.40 of the debates in which he participated. Which statement is not true about Byron's debates?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Since Bryon won 0.40 of his debate, this means that he won 40% of his debate. 40% converted to fraction equals 40/100 = 2/5.
Since he won 40%, it means that he lost (100% - 40%) = 60%. He lost 3/5 and won 2/5.

Brayden stated that a flying disc had a circumference of 43.96 in. Eliza wanted to find the area of the same flying disc. What is the area of the flying disc rounded to the nearest whole number? Both Brayden and Eliza used 3.14 for π
Answer:
=153.86
Step-by-step explanation:
Circumference: 43.96
43.96/3.14= 14 = diameter
14/2= 7 = radius
area= 3.14(7)^2
=3.14(49)
=153.86

What is the value of x?
Answer:

Step-by-step explanation:
round to the nearest tenth
Answer:
Step-by-step explanation:
Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274:
Rounding to the nearest hundred is 800
Rounding to the nearest ten is 840
Rounding to the nearest one is 838
Rounding to the nearest tenth is 838.3
Rounding to the nearest hundredth is 838.27
Basic Rules of Rounding
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Round to the Nearest Hundred: 3250
Identify the hundreds digit: the 2 in 3250
Identify the next smallest place value: the 5 in 3250
Is that digit greater than or equal to five? Yes, so round up.
Increase the hundreds digit by one, so 2 becomes 3. Every digit after becomes a zero.
3250 rounded to the nearest hundred is 3300
Round to the Nearest Ten: 323.5
Identify the tens digit: the 2 in 323.5
Identify the next smallest place value: the 3 in 323.5
Is that digit greater than or equal to five? No, so round down.
The tens digit stays the same at 2. Every digit after becomes a zero. Digits after the decimal point are dropped.
323.5 rounded to the nearest ten is 320
Round to the Nearest Ten: 499
Identify the tens digit: the first 9 in 499
Identify the next smallest place value: the second 9 in 499
Is that digit greater than or equal to five? Yes, so round up.
The tens digit increases by one. Since 9+1=10, you need to carry the 1 and add it to the digit in the hundreds place. Each digit after becomes a zero.
499 rounded to the nearest ten is 500
Round to the Nearest Tenth: 0.74
Identify the tenths digit: 7 in 0.74
Identify the next smallest place value: the 4 in 0.74
Is that digit greater than or equal to five? No, so round down.
The tenths digit stays the same at 7. Since the remaining digits are after the decimal point you just drop them.
0.74 rounded to the nearest tenth is 0.7
Round to the Nearest Hundredth: 3.141
Identify the hundredths digit: the 4 in 3.141
Identify the next smallest place value: the second 1 in 3.141
Is that digit greater than or equal to five? No, so round down.
The hundredths digit stays the same at 4. Drop the digits to the right of 4.
3.141 rounded to the nearest hundredth is 3.14
bill paid $35.99 in tax on a laptop that cost $449.99. about what percent sales tax did bill pay
Answer:
Bill paid about 7% sales tax.
Step-by-step explanation:
First, to find the value of 1%, I divided $449.99 by 100, which gave me 4.4999. I then divided the amount paid for tax by the value of 1%. That;s $35.99 ÷ $4.4999 = 7.199439887977596. Obviously, you can't put that in your math homework, plus the question says "about," so you're going to round. Because the first number after the decimal point is less than five, you round down. Therefore, the sales tax is about 7%.

HELP i need to find area AND perimeter there is a triangle and a rectangle
Answer:
perimeter of this figure is = 54 cm
and area of traingle is = 1/2*base *height
so = 1/2*8*6
=. 24cm*cm
and area of rectangle = length * breadth
area = 112cm*cm
so total area = 112+ 24 = 136cm*cm
hope it helps and your day will full of happiness
Answer:
138 cm^2 = Area . 54 cm = Perimeter
Step-by-step explanation:
Find the area of the triangle- b * h = A
2
8 * 6 = A
2
48/2 = A
24 = A
Find the area of rectangle- l * w = A
16 * 7 = A
112 = A
Add the areas together. 24 + 112 = 136 cm^2
Perimeter is adding up all the sides. s + s + s + s + s
16 + 7 + 8 + 10 + 13 = 54 cm
Si una escalera de bomberos de 37 metros de longitud,se apoya en la pared de un edificio,poniendo el pie de la escalera a 12 metros del edificio, ¿que altura, en metros, alcazan la escalera?
Answer:
La escalera alcanza 35 metros de altura.
Step-by-step explanation:
La altura que alcanza la escalera se puede calcular usando Pitágoras:
[tex] L^{2} = B^{2} + A^{2} [/tex]
En donde:
L: es la longitud de la escalera = 37 m
B: es la distancia del pie de la escalera al edificio = 12 m
A: es la altura =?
Entonces, la altura es:
[tex] A = \sqrt{L^{2} - B^{2}} = \sqrt{(37 m)^{2} - (12 m)^{2}} = 35 m [/tex]
Por lo tanto, la escalera alcanza 35 metros de altura.

PLEASE HELP ASAP ILL GIVE YOU 30 POINTS Jamie is excited for spring break this year. Her family is planning a vacation! She fully intends to take 20 pictures each day. checking her phone before leaving she notices she has 75 pictures already on the phone.
Given that the vacation will last a full seven days and Jamie's phone can hold a total of 200 pictures. How many pictures will she need to delete an order to make enough room in her phone for vacation photos?
Answer:
15 photos
Step-by-step explanation:
one can start off by first seeing how many photos will be taken on the vacation. We can do that by multiplying the days with how many photos will be taken for each- so 20×7= 140. Then we can take the total amount of photos the phone cam hold-200 subtract what we already have 200-75= 125 thats how much space if left but we need more (140). So the. we can start making quick guesses by taking 5 from 75 and see what we get then taking another 5 and another if needed we get 60 that finally gives when subtracted from 200- 200-60=140 the amount of space we need. Then finally we can just do 75-60 to get the total amount of photos we must delete. 75-60= 15
Simplify. Assume that no denominator is equal to zero. (show work)
