what is the midpoint of 23.8 and 23.7?
Answer:
23.75
Step-by-step explanation:
Answer:
23.75
Step-by-step explanation:
1. 23.8 - 23.7 = 0.1
2. 0.1 ÷ 2 = 0.05
3. 0.05 + 23.7 = 23.75
this works because to find the middle of two numbers (in this explanation 10 and 20), you have to subtract the larger one from the smaller one (20 - 10 = 10) and take your sum and divide it by two (10 ÷ 2 = 5) and then add it back to the smaller number (5 + 10 = 15 = 1/2 the midpoint of 10 and 20)

Answer:
1) x: small #; y: large #
4y = 7x
x + y = 22
----------------
-7x + 4y = 0
x + y = 22
---multiply the second equation by -4------
-7x + 4y = 0
-4x - 4y = -88
----solve------
-11x = -88
x = 8
---substitute with any of the equation above i chose the very first one------
4y = 7(8)
4y = 56
y = 14
x = 8; y = 14
2) x = small #; y = large #
y - x = 15
5x = y - 9
----after rearranging, solve-----
-x + y = 15
5x - y = -9
-4x = 6
x = -1.5
--------substitute--------
-(-1.5) + y = 15
1.5 + y = 15
y = 13.5
x = -1.5; y = 13.5
3) x = lemon cream; y = fudge cookie
3x + 2y = 400
2x + 3y = 425
----multiply the first equation by -2, multiply the second equation by 3------
-6x - 4y = -800
6x + 9y = 1275
----solve------
5y = 475
y = 95
--------substitute--------
3x + 2(95) = 400
3x + 190 = 400
3x = 210
x = 70
x = 70; y = 95
Desiree has $36 in her bank account. She spends $14.50 on dinner and tickets to a basketball game.
Which equation is set up to determine how much money Desiree has left in her bank account correctly, and how much money does she have left?
The equation x + 14.50 = 36 is used to determine how much money Desiree has left, and she has $21.50 left.
The equation x + 14.50 = 36 is used to determine how much money Desiree has left, and she has $21.50 left.The equation 14.50 + 36 = x is used to determine how much money Desiree has left, and she has $50.50 left.
The equation 14.50x = 36 is used to determine how much money Desiree has left, and she has $21.50 left.The equation 36x = 14.50 is used to determine how much money Desiree has left, and she has $50.50 left.
Answer:
B
X is how much is left, so adding the money spent to that should equal 36.

Find the area of the triangle. Round your answer to the nearest 10th.
6
2
Answer:
6 or possibly 6.0
Step-by-step explanation:
The area of a triangle is equal to the height x base divided by 2, which is basically h × w ÷ 2. So it's 2 × 6 ÷ 2, which equals to 6. If rounded, it should possibly be 6.0.
The complement of the angle is 1/2 of the measure of the angle. Find the measure of the angle.
Group of answer choices
1.180°
2.90°
3.60°
4.30°
Answer:
choice 2) x = 60°
Step-by-step explanation:
the complement of an angle is an angle that when added to the original angle = 90°
so:
x + 0.5x = 90°
1.5x = 90°
x = 90/1.5 = 60°

Answer:
2. 200.52 4. 212.67 5. 148.48
Step-by-step explanation:
for (2) you find the area of each shape first the square
12*12=144
then you find the area of the semicircle
the formula is A= (3.14)r^2/2
the (r) is 6 because that is half of the whole side of the semicircle
so... (3.14) 6^2/2
6*6= 36
(3.14)36/2
113.04/2
56.52
then add the 144 from the square to it
56.52+144
200.52
question (4)
-85.5 (area of the triangle)
-127.17 (area of the semicircle)
212.67
question (5)
-48( area of triangle)
-100.48 (area of semicircle)
148.48

How many times would you predict to roll a sum of 12 out of 180 rolls? Show your work.
Answer:
5.
Step-by-step explanation:
On 1 roll of 2 dices probabilty of 12 = 1/6 * 1/6 = 1/36
So the prediction ffor 180 rolls
= 1/36 * 180
= 5

Answer question 17 and I will give you brainlest. The second photo is what you need to use to answer the question.
Answer: 23°
Step-by-step explanation:
First, we need to find the missing angle to the left of x
Let's take what we are given
which is 130°, As you notice the angle of 130° is on a straight line
A straight line is supposed to equal 180°
So we can take 180°-130° which will equal 50°
Now we know that the missing angle next to x is 50°
Now we need to take 107° and add it to 50
Which will equal 157°
Now to get x, we need to take 180°-157°
Which will equal 23°
x=23°

Valeria already has $65 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $200 in her account.
Answer:
65 + 5x ≥200
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.
Mathematically speaking:
65 + 5x ≥200
If we solve it for x:
5x ≥200-65
5x ≥135
x ≥ 135/5
x ≥ 27 weeks

How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explain one of the two or how their similar and different. Thanks :)
I give brainliest to whichever makes the most sense
Answer:
They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.
In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.
