A recipe requires 3 cups of sugar. You can only measure using 2/5 cups. how many 2/5 cups are needed for the recipe
To find how many 2/5 cups are needed for 3 cups of sugar, divide 3 by 2/5, resulting in 7.5. Therefore, 7.5 of the 2/5 cups are required.
To calculate how many 2/5 cups are needed for a recipe that requires 3 cups of sugar, you can follow these steps:
Determine the total amount required: The recipe requires 3 cups of sugar.
Determine the measurement of the cup you have: You can measure using only 2/5 cups.
Calculate the number of 2/5 cups needed: Divide the total amount needed by the measurement of the cup you have.
This gives you the equation: 3 cups \/ (2/5 cups) = 15/2 = 7.5. Therefore, you will need 7.5 of the 2/5 cups to measure out 3 cups of sugar.

Jose needs 6.2 lb of organic blueberries to make smoothies. Organic blueberries are on sale for $2.85 per pound. Jose estimates that he will need $12 to buy the 6.2 lb of blueberries. What is Jose’s error?
Jose did not make an error. His estimate of $12 is correct.
Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
Jose incorrectly rounded 6.2 up to 7.
Jose incorrectly multiplied 2 and 7. The estimate should be $14.
Answer:
Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
Step-by-step explanation:
When we round 6.2 lb to the nearest pound we round down, because the digit after point is less than 5 (2<5), so
[tex]6.2\ lb\approx 6\ lb[/tex]
When we round $2.85 to the nearest dollar we round up, because the digit after point is greater than 5 (8>5), so
[tex]\$2.85\approx \$3[/tex]
Now, 6.2 lb of blueberries will approximately cost
[tex]\$3\cdot 6=\$18[/tex]
Hence, Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
Answer:
answer is B Jose incorrectly rounded $2.85 down to $2. The estimate should be $18. have a great day.

Step-by-step explanation:
The correct question is
Find the measure of angle JAM
See the attached figure to better understand the problem
step 1
Find the measure of angle JAK
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
so
m∠JAK=(1/2)[arc KJ+arc LM]
substitute the given values
m∠JAK=(1/2)[170°+80°]=125°
step 2
Find the measure of angle JAM

can you divided 14 shirt into 2 equal piles why or why not
Answer:
Yes you can because 14 is a even number.
Step-by-step explanation:
First you divide 14 by 2 to get two equal piles and boom there's your answer.
Yes, you can divide 14 shirts into 2 equal piles, due to the fact that 14 is an even number.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
The solution is as simple as dividing 14 by 2 to produce two equal piles.
⇒ 14/2
⇒ 7
Thus, you can divide 14 shirts into 2 equal piles, due to the fact that 14 is an even number.

The legs of a triangle measure 13 centimeters and 17 centimeters. Which of
the following is the measure for the longest side of the triangle?
O A. 30 cm
O B. 4 cm
O C. 31 cm
O D. 29 cm
SUBMIT
Answer:
D. 29 cm.
Step-by-step explanation:
The measure of the longest side cannot be equal or greater than (17 + 13) = 30 cm or it wouldn't be a triangle.
So it cannot be 30 or 31 cm long. Also as we want the longest side so it can't be 4 cm.
The answer is 29 cm.

A living room measures 24 feet by 15 feet. An adjacent square dining room measures 13 feet on each side. If carpet costs $6.98 per square foot, what is the total cost of putting carpet in both rooms?
Answer:
total cost of putting carpet in both rooms is $3692.42
Step-by-step explanation:
given data
living room length = 24 feet
living room width = 15 feet
dining room is square so length and width will be same
dining room length = 13 feet
dining room width = 13 feet
carpet costs = $6.98 per square foot
to find out
what is the total cost of putting carpet in both rooms
solution
first we find the total area of both room that is
area of living room = length × width .................1
area of living room = 24 × 15
area of living room = 360 feet² ...........................2
and
areas of dining room = length × width
area of dining room = 13 × 13
area of dining room = 169 feet² ...............................3
so total area = add equation 1 and 2
total area = 360 feet² + 169 feet²
total area = 529 feet²
and
total cost of putting carpet in both rooms are = total area × carpet costs .................4
put here value
total cost of putting carpet in both rooms = 529 × $6.98
total cost of putting carpet in both rooms =$3692.42
The calculated total square footage that needs carpeting is 529 square feet. At $6.98 per square foot, the total cost of carpeting both rooms would be $3,690.42.
Explanation:The subject of this problem is mathematics, specifically the topic of area calculations and cost analysis. First, calculate the area for both rooms. The area of a rectangle is given by the formula length x width, so the area of the living room is 24 feet x 15 feet which equals 360 square feet. As the dining room is a square, its area is side x side, thus 13 feet x 13 feet equals 169 square feet.
Then, add these to get the total square footage that will need carpeting, which is 360 + 169 = 529 square feet.
Lastly, multiply this total area by the cost per square foot for carpeting. This gives $6.98 x 529 square feet = $3,690.42. So, the total cost of carpeting both rooms would be $3,690.42.

Solve for x and Y using the angles shown, please helppp
Answer:
x = 6
y = 24
Step-by-step explanation:
(14x + 4) + (16x - 4) <--- you add them because they are supplementary angles and are equal to 180°
(14x + 4) + (16x - 4) = 180
30x = 180
[tex]\frac{30x}{30} = \frac{180}{30}[/tex]
x = 6
Then you plug in 6 to (14x + 4)
(14(6) + 4) = 84 + 4 = 88
180 - 88 = 92
Now subtract 92 from 180 and make it equal to (4y - 8) to get y.
(4y - 8) = 180 - 92 ---> (4y - 8) = 88
+ 8 + 8
4y = 96
[tex]\frac{4y}{4} = \frac{96}{4}[/tex]
y = 24
Answer:
x = 6, y = 24Step-by-step explanation:
We have the vertical angles and supplementary angles.
Vertical angles are congruent. Therefore we have the equation:
[tex](1)\qquad14x+4=4y-8[/tex]
Supplementary angles add up to 180°. Therefore we have the equation:
[tex](2)\qquad(16x-4)+(14x+4)=180[/tex]
Solve (2):
[tex](16x-4)+(14x+4)=180\qquad\text{combine like terms}\\(16x+14x)+(-4+4)=180\\30x=180\qquad\text{divide both sides by 30}\\x=6[/tex]
Put the value of x to (1) and sole:
[tex]4y-8=14(6)+4\\4y-8=84+4\\4y-8=88\qquad\text{add 8 to both sides}\\4y=96\qquad\text{divide both sides by 4}\\y=24[/tex]
Seth traveled 1 mile in 57.1 seconds how many miles per hour does he drive
one hour has 60 minutes, each minute has 60 seconds, so then an hour has 60*60 seconds, namely 3600 seconds. How many miles does Seth travel in 3600 seconds?
[tex]\bf \begin{array}{ccll} miles&seconds\\ \cline{1-2} 1&57.1\\ x&3600 \end{array}\implies \cfrac{1}{x}=\cfrac{57.1}{3600}\implies 3600=57.1x \\\\\\ \cfrac{3600}{57.1}=x\implies 63.05 \approx x[/tex]
Answer:
In order to find miles per hour we must first change the time given to us (57.1 seconds) into hours. We will do this by first changing the seconds to minutes:
57.1 seconds / 60 = .952 minutes
Now we can change our minutes to hours:
.952 minutes / 60= .016 hours
Now to find miles per hour we divide the miles by our time:
1 mile / .016 hours = 63.04 mph
