Round each number to the specified place value.
81.23 (whole number-ones)
13.567 (tenths)
Answer:
81
13.6
Step-by-step explanation:
When rounding 81.23 to the ones place, look at the following spot, the tenths place, to determine whether to round up or down. If the value is 4 or less, round down. If the value is 5 or greater, round up. 2 is less than 4, so round 81.23 to 81.
Since we're looking to round 13.567 to the nearest tenth, look at the value of the number in the hundreths spot. Repeat the same process as above. 6 is greater than 4, so round 13.567 to 13.6.

Simplify the expression by combining like terms
Answer:
[tex] \sf \: {7a}^{2} + 6a + 4 [/tex]
Step-by-step explanation:
Given expression,
→ 1 + 5a + 7a² + a + 3
Let's simplify the expression,
→ 1 + 5a + 7a² + a + 3
→ (7a²) + (5a + a) + (1 + 3)
→ (7a²) + (6a) + (4)
→ 7a² + 6a + 4
Hence, answer is 7a² + 6a + 4.
Find the value of the variables
Answer:
x=2
y=7
Step-by-step explanation:
Since we know that the object is a rectangle, we know that the opposite sides are equal to each other. Thus:
9 = y+2
and
2y = 7x
Using algebra we can solve the first equation:
9 = y+2
9-2 = y
7 = y
Now we can use substitution:
2y = 7x
2(7)=7x
14=7x
x=2
Find the length of the missing side
Answer:
52
Step-by-step explanation:
To solve, use the Pythagorean Theorem, which says c² = a² + b². Enter 20 as a and 48 as b and square them both. This will give you 400 for a, and 2304 as b. Add them to get 2704. So, c² = 2704. Find the square root of this to get 52. So, the third side is 52 in length.
Emma goes miniature golfing. She pays $7.50 for an admission ticket and $6.25 for each round she golfs. The total amount Emma pays for admission and the number of rounds she golfs is $26.25. Which equation can be used to determine the number of rounds, x, that Emma golfs?
Answer:
The equation that can be used to determine the number of rounds that Emma golfs is:
x=(c-7.50)/6.25
Step-by-step explanation:
From the information given, the total amount Emma pays to go miniature golfing is equal to the price of the admission ticket plus the result of multiplying the price per round of golf for the number of rounds and according to this, the equation would be:
c=7.50+6.25x, where:
c is the total cost for Emma to go miniature golfing
x is the number of rounds
Now, you can solve for x to determine the equation that can be used to find the number of rounds that Emma golfs:
x=(c-7.50)/6.25
You can replace c with 26.25:
x=(26.25-7.50)/6.25
x=18.75/6.25
x=3

What is the coordinate of the solution for the following equations? y = 4x – 9 y = -3x + 12
Answer:
x = 60/17, y = 24/17
Step-by-step explanation:
What is the image point of (1, 2) after a translation right 5 units and up 3 units?
Therefore the image point of (1, 2) is (6, 5)
Given point is (1, 2) considered as (x, y)
We know that in the coordinate axis horizontal line represents the x-axis and the vertical line represents the y-axis.
In that, a point that moves right means it goes positive x-axis.
If the point moves left means it goes negative x-axis.
If the point moves up means it goes positive y-axis.
If the point moves down means it goes negative y-axis.
By using the above points we can solve this question as
Given we need to find the image point of (1, 2) after a translation right 5 units and up 3 units.
Now the point on the x-axis changes to 5 units right as
= x + 5
= 1 + 5
= 6
Now the point on the y-axis changes to 3 units up as
= y + 3
= 2 + 3
= 5
Therefore the image point of (1, 2) is (6, 5).

Answer:
they are parallel lines with a crossing line creating a 90 degree angle
The line A and line B are parallel to each other and line C is perpendicular to both line A nd B.
What is converse of consecutive interior angle theorem ?
As a result of the converse of consecutive interior angle theorem, two parallel lines are formed whenever a transversal intersects two lines so that two consecutive interior angles are supplementary.
Any pair of angles that lie on opposite sides of two lines cut by a transversal on the same side is known as corresponding angle.
Here, the angle ∠d and angle ∠h are corresponding angles and there measurement is 90 degrees which implies that the line A and line B parallel to each other and line C is perpendicular to both line A nd B.

The height of a painting is 65ft. between which two consecutive whole numbers is 65?
The height of painting lies between 8 and 9 feet.
The square numbers before and after 65 are 64 and 81 respectively. Further, 64 is the square of 8 and 81 is the square 9. This indicates that √65 will lie between the whole numbers 8 and 9. The whole numbers are defined as the numbers who are an integer and do not have fractions.
Since 65 is close to square number 64 rather than square number 81, the square root of 65 should also be close to the whole number 8.
Thus, it is evident that height of the walls lie between two consecutive whole numbers 8 and 9.

Example 3: The following data was collected by a taxi driver who was interested in how much fuel he used on different journeys. Length of journey 100 250 150 180 220 (miles) 300 Fuel Used (liters) 24 59 44 50 59 97 Estimate how much fuel would be needed for a 200-mile journey.
Answer:
For a 200 mile journey, 55.5 liters of fuel
is needed
Step-by-step explanation:
Here, we want to estimate the fuel needed for a 200 mile journey
we can use this by having an average
By adding all and dividing by 6
Mathematically, that will be;
(24 + 59 + 44 + 50 + 59 + 97)/6
= 55.5
The reason for this is because if we added all the lengths and divide by 6, what we get is 200
Thus, if we added the liters of fuel used per each and divide by 6, we can have an estimate for a 200-mile journey

Solve the equation. Enter your answer in the box. 42 = y + 15
Answer:
y=27
Step-by-step explanation:
Simplifying
42 = y + 15
Reorder the terms:
42 = 15 + y
Solving
42 = 15 + y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-1y' to each side of the equation.
42 + -1y = 15 + y + -1y
Combine like terms: y + -1y = 0
42 + -1y = 15 + 0
42 + -1y = 15
Add '-42' to each side of the equation.
42 + -42 + -1y = 15 + -42
Combine like terms: 42 + -42 = 0
0 + -1y = 15 + -42
-1y = 15 + -42
Combine like terms: 15 + -42 = -27
-1y = -27
Divide each side by '-1'.
y = 27
Simplifying
y = 27
