Answer:
the height of the cross section is 3 feet
Step-by-step explanation:
The computation of the height of the cross section is shown below:
Area = 1 ÷ 2 × (a + b) × h
39 = 1 ÷ 2 × (20 + 6) × h
39 = 1 ÷2 × 26 × h
39 = 26 ÷ 2 × h
39 = 13 × h
h = 39 ÷ 13
= 3 feet
hence, the height of the cross section is 3 feet

round 33.885 to the nearest 100th
Answer:
33.89
Step-by-step explanation:
How to Calculate Rounding to the Nearest 100th?
If the digit after hundredth is greater than or equal to 5, add 1 to hundredth. Else remove the digit. Example

The third digit of right of decimal point is 6
The second digit after decimal point is 8 which is greater than 5
So add 1 to 8
Result = 124.59
Answer:
it's 33.89 hope it helps

what is the additive inverse of 3?
a. -3
b. a+(-a)=0
c. 0
d. -a
Answer:
a. -3
Step-by-step explanation:
Two numbers are additive inverses if they add to give a sum of zero. 3 and -3 are additive inverses since 3 + (-3) = 0. So, -3 is the additive inverse of 3.

Answer:
(1) commutative property of the addition.
(2) distributive property of the multiplication and associative property of the addition.
(3) addition property of the equality.
(4) multiplication property of the equality.
Step-by-step explanation:
First we start with:
4x + 1 + x + 3 = -11
Here we use the commutative property of the sum, which says that:
A + B = B + A
So we can reorder the terms in a sum, and we can rewrite our equation as:
4*x + x + 3 + 1 = -11
Here we also used the associative property of the sum, that says that:
A + B + C = (A + B) + C = A + ( B + C)
wich means that we can perform the sum in any order we want, then we can add the 3 and the 1
4*x + x + 4 = -11
Now we use the distributive property of the multiplication, which says that:
(A + B)*C = A*C + B*C
Then we can rewrite our equation as:
(4 + 1)*x + 4 = -11
Now we solve the sum in the parentheses to get:
5*x + 4 = -11
Now we can use the addition property of the equality, we can add (-4) in both sides to get:
5*x + 4 - 4 = -11 - 4
5*x = -15
Now we can use the multiplication property of the equality, and multiply both sides by (1/5) to get:
5*x*(1/5) = -15*(1/5)
x = -5

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 9 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
about 15.6cm.
Step-by-step explanation:
I got my answer of 15.6cm because I did the Pythagorean theorem.
a^2+b^2=c^2
The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.
Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.
In conclusion, the measure of the other leg is about 15.6cm.

4). Machine “B” can pack 11 boxes per minute. The factory receives an
order for more than 1100 boxes. Machine B has already packed 55 boxes.
Write and Solve an inequality to find the amount of time it will take machine
B to pack the additional boxes that are needed for the order.
Answer:
Amount of time would be greater than 95 minutes
Step-by-step explanation:
We are told that machine B can pack 11 boxes per minute.
Thus, this is 11x where x represents number of minutes.
We are told that the factory revives an order of over 1100 boxes and that it had already packed 55.
Thus,the inequality equation is;
11x + 55 > 1100
Solving this;
11x > 1100 - 55
11x > 1045
x > 1045/11
x > 95 minutes
which ordered pair is a solution of the inequality y > 13x + 3
Answer:
x<y-3/13
Step-by-step explanation:
Switch sides'
13x+3<y
Subtract 3 from both sides
13x+3-3<y-3
Simplify
13x<y-3
Divide both sides by 13
13x/13<y/13-3/13
Simplify
x<y-3/13

what is the diameter of the circle: x^2+y^2=16 ?
Answer:
The diameter of this circle is equal to 8
Step-by-step explanation:
The standard form of a circle is equal to x^2 + y^2 = r^2. As this equation shows x^2 + y^2 = 16, all we have to do is find the square root of 16, which is 4. This means that 4 is the radius of the circle and that 2 * 4 = 8, which is the diameter of the circle.
Because of this, the diameter of this circle is equal to 8.

Step-by-step explanation:
First, we need to find the area of the rectangle that the triangle RST is in, which would be 4*5=20. Second, we need to subtract the three triangles so the remaining area would be the area of the triangle that we need to solve for. The sum of the areas of the three triangles would be: 1/2*2*5 + 1/2*2*2 + 1/2*4*3 = 5 + 2 + 6 = 13.

Sheyna has less than 180 minutes to decorate 60 cookies for the bake sale. How long can she spend decorating each cookie to stay within her time limit? (a) Write and solve an inequality.
Answer:
m < 3
Step-by-step explanation:
Cookies to decorate = 60
Time < 180 minutes
The inequality
60m < 180
Where,
m = number of minutes
60m < 180
m < 180/60
m < 3
Less than 3 minutes decorating each cookie
javier bought a microwave for $105. the cost was 30% off the orginal price. what was the price of the microwave before the sale? Step by Step
Answer: price was $150
Step-by-step explanation: original price was x. When discount is 30%
Price is (100-30)% = 70 % from the original. 70% = 0.70
So we have an equation 0.7x = 105. And x= 105/0.7= 150

A basket of snacks contains 8 packs of oreos, 2 bags of chips, 6 packs of gummies, and 4 granola bars. Bill randomly choses 2 snacks. What is the probability a granola bar is chosen one choice after the other without replacing the first bar? {PLZZZZ HELP}
Answer:
There is a 3/95 probability that a granola bar is chosen one choice after the other without replacement.
Step-by-step explanation:
The probability of choosing a granola bar without replacing the first bar is 4/20, or 1/5. 4 represents the number of granola bars, and 20 represents the total snacks. Then there are 19 snacks and 3 granola bars which represents the 3/19 chance of getting a granola bar the second time without replacing it.
To find the probability of both of those events happening, multiply them.
(1/5) * (3/19) = 3/95.

Using this information, each student can prepare an infinite number of parallelograms
Step-by-step explanation:
The given parameters of the parallelogram Emily asks the students to bring are;
The measure of one of the angles of the parallelogram = 50°
The length of of one side of the parallelogram = 10 cm
The shapes which the parallelogram must not be are; rhombus, rectangle, or square
Using the given information, therefore, the number of different parallelograms the students can prepare is given as follows;
The number of different lengths of the other side of the parallelogram = Infinity - 1 = Infinity
Therefore, the number of different parallelograms the students can prepare is an infinite number of parallelograms
