Answer:
One solutionKind Note:
This question is incomplete. You need to provide the question in order to get the best answer on brainly. In this answer, I will tell you how many solutions are in this system of equations.
Step-by-step explanation:
This question involves the use of 'system of equations'.
=> -3x - 7y = 83x - 2y = 44
=> (-3x + 3x) + (-7y - 2y) = (8 + 44)=> -9y = 52=> y = -52/9 (No further check required)Since the y-intercept is valid, the system of equations has one solution.
Hence, this system of equations has one solution.

Sandy spun a spinner with 5 equal parts labeled 1-5. If she spins the spinner 20 times, how many times should she expect to spin a 2
Answer:
4 times
Step-by-step explanation:
[] If the spinner has 5 equal parts labeled 1 through 5, then the chance to spin a 2 is 1/5 because only one of the pieces has a 2.
[] Our whole is 20 because the spinner is spun 20 times
20 * 1/5 = 4
[] Sandy can expect to spin a 2 4 times.

true or false: The range for an exponential function includes all real numbers.
False, The range for an exponential function does not include all real numbers but only real numbers greater than zero.
What is exponential function?In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.
Given statement,
The range for an exponential function includes all real numbers.
By the definition,
Exponential functions have the general form y = f (x) = aˣ,
where a > 0, a≠1, and x is any real number.
The reason a > 0 is that if it is negative, the function is undefined for -1 < x < 1. Restricting a to positive values allows the function to have a domain of all real numbers.
Thus the range is all real numbers greater than zero.
Hence, The range for an exponential function includes all real numbers is False because it includes real numbers greater than zero.

a recipe for cookies calls for 2/3 of a cup of sugar per batch. elena used 6 2/3 cups of sugar to make multiple bathes did she make
Answer:
Elena made 10 batches.
Step-by-step explanation:
1 batch uses 2/3 cup
Elena used 6 2/3 cup
The number of batches is the quotient of 6 2/3 and 2/3.
We need to divide 6 2/3 by 2/3. First, we convert 6 2/3 into a fraction.
6 2/3 ÷ 2/3 = 20/3 ÷ 2/3 = 20/3 × 3/2 = 10
Answer: Elena made 10 batches.

Five squares are positioned as shown. The small square indicated has area 1 . What is the value of h?
Answer:
4
Step-by-step explanation:
Each box is 1 larger than the earlier one, so the boxes are 1, 2, 3, 4, and 5.
4 + 5 is the width across the bottom
2 + 3 is the width across the top (not counting h)
9 - 5 = 4, so h = 4
The value of h is 4. Hence, Option C is the best choice.
Found using the area of the given square.
What is the area of a square?The area of a square is the square of its sides.
If a represents the side of the square, then its area is a².
How to solve the given question?In the question, we are given five squares positioned as shown in the figure. The smallest square has an area of 1.
We are asked to find the value of h.
Now, the square of area 1, will have sides of length √1 = 1.
The second square, just greater than this, is nearly 1.5 times this square.
Hence the side of that square = 1.5*1 = 1.
The third square has a side equal to the sum of the side of these two squares. Hence, its side = 1 + 1.5 = 2.5.
The fourth square has a side equal to the sum of the third and the first square. Hence, its side = 2.5 + 1 = 3.5.
The fifth square has a side equal to the sum of the fourth and the first square. Hence, its side = 3.5 + 1 = 4.5.
Now, h = length of the fifth square - (length of the second square - length of the first square),
or, h = 4.5 - (1.5 - 1) = 4.5 - 0.5 = 4.
Hence, the value of h is 4. Hence, Option C is the best choice.

Find the area of a circle with : (vi) circumfernece = 66 cm
Answer:
7.07 cm
Step-by-step explanation:
we know,
circumference = 2πr
so,
2 × 22/7 × r = 66
44r = 66×7 = 462
r = 462/44 = 1.5
therefore, radius of the circle is 1.5 cm.
now,
we know , area = πr²
so,
22/7 × (1.5)²
22/7 × 2.25
49.5/7
7.07 cm (approx)
therefore, area of the circle is 7.07 cm (approx.)
hope this answer helps you!
