31 workers are working on a construction site. 5 more workers work for company A than for company B. How many workers work for each company?
25pts
Answer:
18 work for company A and 13 for company B
Step-by-step explanation:
Company A = A
Company B = B
A = B + 5
A + B = 31
B + 5 + B = 31
2B + 5 = 31
2B = 26
B = 13 -->
A = 13 + 5
A = 18
A spinner is divided into 4 equal parts. 1 part is colored red, 2 parts are colored blue, and 1 part is colored yellow. The spinner is spun 1000 times. Select all of reasonable possible outcomes
The sections on the spinner are used to illustrate probability
The reasonable possible outcome is that the expected outcomes of the red section and the yellow sections are the same
How to determine the possible outcomesThe sections in the spinners are:
Red = 1Blue = 2Yellow = 1Total = 4From the above parameters, the probability of each section is:
P(Red) = 1/4
P(Blue) = 1/2
P(Yellow) = 1/2
When the spinner is spun 1000 times, the expected outcomes are:
Red = 1/4 * 1000 = 250
Blue = 1/2 * 1000 = 500
Yellow = 1/4 * 1000 = 250
From the above calculations, we can determine that the reasonable possible outcome is that the expected outcomes of the red section and the yellow sections are the same

A basketball player has 45 steals, 72 assists, 90 rebounds, and 432 points. What is
the ratio of rebounds to steals?
оооо
Answer:
5:24
Step-by-step explanation:
We're provided with the number of rebounds as 90 while the points are 432. Expressing them into ratio of rebounds to steals we have
90:432
Simplification:
Dividing both sides by 2 we obtain
45:216
Dividing both sides of the above ratio by 3 we obtain
15:72
Dividing both sides of the above ratio further by 3 we obtain
5:24
Therefore, rhe simplified ratio of rebounds ro steals is 5:24

Which expression is equal to 7/8
A. 7 divided by 8
B. 8 x 7
C. 8 divided by 7
D. 7 x 8
Answer: A. 7 divided by 8.
Step-by-step explanation:
7/8 is the same as saying seven divided by 8.
The correct answer to the question: 'Which expression is equal to 7/8?' is A. 7 divided by 8. This is because the '/' in the fraction 7/8 represents division, so 7/8 is the same as '7 divided by 8'.
Explanation:In Mathematics, when dealing with fractions, division, and multiplication, it's crucial to understand their relationships. The symbol '/' in a fraction actually represents division. So, the fraction 7/8 can be interpreted as '7 divided by 8'. Therefore, the correct answer to your question is: 'Which expression is equal to 7/8?' is A. 7 divided by 8.
On the other hand, options B and D (8 x 7, 7 x 8) represent multiplication and C (8 divided by 7) is a different division operation where 8 is divided by 7, not 7 by 8.

sixty-three less than 15 times a number is 72. what is the number?
Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = -3/5
Answer:
-3/5
Step-by-step explanation:
The equation would be represented as 63 - 15 x X = 72
To further simplify the problem : 63 - 15x = 72
Then you subtract

Find the vertical and horizontal difference between the two given points:
Horizontal is the Y values: 4 - -4 = 4+4 = 8
Vertical is the X values 7 - -1 = 7+1 = 8
Multiply the changes by the ratio:
Now copy the dot on A 2 places to the left and down 2 places and the dot lands on point (5,2)
8 * 1/4 = 2
AC in the horizontal and vertical direction is 8 units. AB in the horizontal and vertical direction is 1/4 of 8 which is 2 units. To find the coordinates of B on the graph, move 2 units to the left and 2 units down. We lie on the point (5, 2).

Estimate the solution to the system of equations 2x+3y=6 -4x+3y=12
The solution of the system is x = - 1 and y = 8/3.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
We have a system of equations,
2x+3y=6 {equation 1}
-4x+3y=12 {equation 2}
Subtracting equation 2 to equation 1,
2x - (-4x) = 6 - 12
6x = - 6
x = - 1.
And y = 8/3
Therefore, the solution is x = - 1 and y = 8/3.

Vanessa draws one side of an equilateral triangle ABC on the coordinate plane at points A(-2, 1) and B (4, 1). What are the two possible coordinates of vertex C? Round to the nearest tenth.
Answer:
two vertex are: (1 , 6.2) , (1 , - 4.2)
Step-by-step explanation:
A(-2, 1) and B (4, 1) AB is a parallel segment with x axis
The 3rd vertex P (x , y) will locate at the mid point of AB
x = (-2) + (4 - (-2)) /2 = 1 P (1 , y)
length AB = 4 - (-2) = 6
AP = AB (equilateral)
BP² = (4 - 1)² + (1 - y)² = 6²
1 - 2y + y² = 36 - 9 = 27
y² - 2y -26 = 0
y = ((-(-2)) ± √(-2)² - 4 x (-26)) / 2 = (2 ± √108) / 2 = 1 ± 5.2
y = 6.2 or y = -4.2
P (1 , 6.2) or P ( 1 , -4.2)
To find the possible coordinates of vertex C of an equilateral triangle with side AB on the coordinate plane, we calculate the midpoint of AB and use the length of the altitude to find two possible positions for C, approximated as (1, 6.2) and (1, -4.2).
Vanessa draws one side of an equilateral triangle on the coordinate plane at points A(-2, 1) and B (4, 1). To find the possible coordinates of vertex C, we first recognize that in an equilateral triangle, all sides are of equal length, and the altitude forms a 60-degree angle with the base.
Given points A(-2, 1) and B(4, 1), the distance AB is 6 units. Using the Pythagorean theorem in a 30-60-90 right triangle, the length of the altitude (half of the triangle height) from the midpoint of AB to C is 3√3. To find coordinate C, we add and subtract this distance from the midpoint of AB, which we calculate as ((-2 + 4)/2, (1 + 1)/2) = (1, 1).
Thus, the two possible coordinates for C are (1, 1 + 3√3) and (1, 1 - 3√3), which approximately are (1, 6.2) and (1, -4.2), rounding to the nearest tenth.
Which type of triangle can have only acute angles?

Answer:
Equilateral triangles can have only acute angles because acute angles means less than 90° so every angles in equilateral triangle have 60°
Estimate the quotient by rounding each number to the nearest whole number. 33.7/ 9.5
Answer: 34/10=3.4 The estimated quotient is 3.4
Step-by-step explanation: Basically, you are dividing 33.7 by 9.5, but first you will need to round to the nearest whole number. A whole number does not contain a decimal. 33.7 rounded to the nearest whole number is 34. 9.5 rounded to the nearest whole number is 10. So, you are dividing 34 by 10. 34 divided by 10 is 3.4.
The quotient of 33.7/9.5, rounded to the nearest whole number is: 4.
What is Quotient of Two Numbers?Quotient of a two numbers, "a" and "b" equals a/b.Quotient means division.Therefore, the quotient between 33.7 and 9.5 would be:
33.7/9.5 = 3.547 (division).
We are asked to round to the nearest whole number.
Therefore, the quotient of 33.7/9.5, rounded to the nearest whole number is: 4.
