x+(2×+0.15)+(×+0.05)=1.8
A. 0.40
B.0.45
C.0.53
D.0.96
Answer:
0.40

Teresa is going to make 3 batches of cookies. She needs 3/4 milk for each. Her measuring cup only holds 1/4 gallon. How many tines will she need to fill up the measuring cup 3 times
Given :
Teresa is going to make 3 batches of cookies.
She needs 3/4 milk for each. Her measuring cup only holds 1/4 gallon.
To Find :
How many times will she need to fill up.
Solution :
Amount of milk need per batch, A = 3/4 gallon.
Measuring cup only holds, m = 1/4 gallon.
Number of times she need to fill up,
n = A/m = (3/4)/(1/4) = 3
Now, number of batches are three.
So, number of time she need to fill up in three batch.
[tex]N = n \times 3 \\\\N = 3 \times 3 \\\\N = 9[/tex]
Therefore, this is the required solution.

Natasha conducted a survey to determine how many of the 215 workers in her office building use public transportation to get to work. She surveyed 30 randomly selected workers who entered the office cafeteria throughout the day. Of the 30 workers surveyed, 9 used public transportation to get to work.
Which change to Natasha's survey process would make the data more reliable?
A. Ask a randomly selected sample of people who use public transportation whether their office is in the building.
B. Use a different sample size so the predicted number of workers who use public transportation is a whole number.
C. Have workers complete a written survey so there is a written record of the responses.
D. Randomly select the sample in the lobby of the building so workers who do not enter the cafeteria can be included.

Find the slope of the line with x intercept 9 and y intercept of -2
Answer:
2/9
Step-by-step explanation:
Find the slope of the line with x intercept 9 and y intercept of -2
Given that the equation of the line is y = mx+b
x intercept occurs when y = 0
The coordinate of x intercept is (9,0)
y intercept occurs at x = 0
The coordinate of y intercept is (0, -2)
Slope m = y2-y1/x2-x1
m = -2-0/0-9
m = -2/-9
m = 2/9
Hence the required slope is 2/9
Calculate the circumference of a circle whose radius is 7.2 Cm (Idek I just woke up lol)
solve for x x(5x+2)=0
Answer:
x = 0.4
x = 2/ 5
Step-by-step explanation:
Answer:
x=0 or x=-2/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x2+2x=0
Step 2: Factor left side of equation.
x(5x+2)=0
Step 3: Set factors equal to 0.
x=0 or 5x+2=0
Hope it helps ;)

The ratio of mango ice cream to strawberry ice cream is 2 : 5 .Total no. of ice cream is 49.what is the no. of strawberry ice cream.
Answer:
35
Step-by-step explanation:
First, we add the ratio of the mango to strawberry ice cream and we're going to end up with 2+5=7. If we divide 49 by 7, we're going to find out how much we need to multiply to both sides of the ratio to get the specific amounts. So, if we multiply 7 (49/7) to 5, we're going to get 35. Therefore the number of strawberry ice cream is 35.
Also, we can check this by multiplying 7 to 2 as well, where we will end up with 14. 35 + 14 = 49 so we know this is correct!
35 is Answer:
Step-by-step explanation: if you do 2:5 and like keep doing it you'll get to a number and another one and it'll make 49

Answer:
2nd option
Step-by-step explanation:
If AB is a tangent to the circle then ∠ B is right angle
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares on the other 2 sides, then the triangle is right
longest side = 52 and 52² = 2704
48² + (10 + 10)² = 48² + 20² = 2304 + 400 = 2704
Then AB is a tangent to the circle since ∠ B is a right angle
