x + (-4) = 10.
We can use the positive - negative rule.
x + (-4) = 10.
x - 4 = 10.
x = 10 + 4
x = 14.
two equivalent fraction for 3/12
Answer:
1/4 and 6/24
Step-by-step explanation:
3 divided by 3 equals 1. So then you have to do the same for the denominator. 12 divided by 3 equals 4. And you get 1/4.
Another is 3 x 2 = 6 and 12 x 2 = 24. 6/24

what did the beaver say to the tree
Answer:
It’s been nice gnawing you
Step-by-step explanation:
While beavers don't 'speak' to trees in human terms, they interact with them by using their teeth to fell trees for food and building materials.
Explanation:The question, 'what did the beaver say to the tree?', is somewhat humorous due to its anthropomorphic implication of a beaver communicating with a tree in human language. But, from a biological perspective, we could interpret this as asking about the interactions between beavers and trees. Beavers, as known dentition specialists, utilize trees for building dams and lodges and as a source of food. So, if a beaver could 'speak', it might 'tell' the tree that it's hungry, or that it needs materials for its dam. Of course, this is all figuratively speaking.

A new species of fish is released into a lake, and the fish multiply quickly. The growth of their population is modeled by the exponential function P(t) = 7bt, where t is the time in weeks after the release and b is a positive unknown base. According to the model, how many fish of the new species were released initially? A) 2 B) 7 C) 12 D) 14
The initial amount of fish released would be the number shown in the equation.
The answer is 7
Final answer:
The initial number of fish released into the lake is 7, which is calculated by substituting t = 0 into the provided exponential growth function, P(t) = 7bt.
Explanation:
The growth of the fish population in the lake is modeled by the exponential function P(t) = 7bt, where t is the time in weeks after the release, and b is a positive unknown base. To find out how many fish were released initially, we need to consider the population at time t = 0. When we substitute t = 0 into the exponential function, we get P(0) = 7b0, and since any number raised to the power of 0 is 1, P(0) = 7. Therefore, the initial number of fish released was 7.

3. Find the area of the triangle.
A. 21.2 in
B. 10.5 in
C. 21 in
D. 42 in
Answer:
C. 21 in² . . . . your answer selection is correct.
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
where b represents the base of the triangle, and h represents the height of the opposite vertex above that base.
The figure shows you that half the base is 3 in and the height is 7 in, so the area is ...
A = (1/2b)h = (3 in)(7 in) = 21 in² . . . . matches choice C

The circumference of a circle is about 37.7 cm and the diameter is about 12 cm. What expression best represents the value of π?
6/37.7
37.7/12
37.7/6
12/37.7
Answer:
The best expression represents the value of π is [tex]\frac{37.7}{12}[/tex] ⇒ 2nd answer
Step-by-step explanation:
π is the ratio between the circumference of the circle and the length of its diameter
[tex]\frac{C}{d}=\pi[/tex] , where
C is the circumference of the circled is the diameter of the circle∵ The circumference of the circle is about 37.7 cm
∵ The diameter of the circle is about 12 cm
- Find the ratio between them
∴ [tex]\frac{C}{d}=\frac{37.7}{12}[/tex]
∵ [tex]\frac{C}{d}=\pi[/tex]
- Equate the two right hand sides
∴ [tex]\frac{37.7}{12}=\pi[/tex]
∴ The best expression represents the value of π is [tex]\frac{37.7}{12}[/tex]
Which step is included in the graph of the function f(x)=[x-1]? (the brackets are ceiling functions symbols)
Answer:
The correct step is y = - 5 for, - 4 ≤ x < - 3.
Step-by-step explanation:
From the definition of a box function y = [x], we know that
y = 0 for, 0 ≤ x < 1
y = - 1 for, - 1 ≤ x < 0
y = - 2 for, - 2 ≤ x < - 1
Here, we are given another box function y = [x - 1], and we have to choose from options the steps which is included in the graph of the this function.
So, the correct step is y = - 5 for, - 4 ≤ x < - 3. (Answer)

If the angular size of a tree at a distance of 0.5 miles is 1/2, how tall is the tree
The tall of the tree is 23.048 ft.
Solution:
Given data:
Angular size of a tree = [tex]\left(\frac{1}{2}\right)^{\circ}[/tex]
Distance = 0.5 miles = 2640 feet
To find the tall of the tree:
Formula to calculate the height of the tree is
[tex]$\text{Physical size}= \text{Angular size}\times\frac{2\pi\times \text{distance}}{360^{\circ}}[/tex]
[tex]$ = \left(\frac{1}{2}\right)^{\circ}\times\frac{2\pi\times 2640}{360^{\circ}}[/tex]
[tex]$ = \left(\frac{1}{2}\right)^{\circ}\times\frac{44\pi}{3^{\circ}}[/tex]
[tex]$ = 23.048[/tex]
Physical size = 23.048 ft
Hence the tall of the tree is 23.048 ft.

At the mall you spent a total of $170.86 if you bought two pairs of jeans for $39.95 each a jacket for $45.99 and shirts for
A total of $170.86 will be spent if you buy shirts for $44.11
Step-by-step explanation:
Step 1:
Let the cost of shirts be $x.
Given that, one pair of jeans costs $39.95, 2 pairs cost 2 * $ 39.95 which is $79.9. Jacket costs $45.99.
Step 2:
Create an equation with this given data.
$170.86 = $x + $79.9 + $45.99
Step 3:
Calculate the value of x from this equation to get the cost of shirts.
$170.86 = $x + $125.89
$x = $170.86 - $125.89
$x = $44.11
Given the following geometric sequence, find the common ratio: {16, 64, 256, ...}.
Answer:
The common ratio is 4
Step-by-step explanation:
We need to divide a term by the previous term to find the common ratio in a geometric sequence:
64 ÷ 16 = 4
256 ÷ 64 = 4
By doing it twice we can confirm that the common ratio is 4
Given the following geometric sequence, the common ratio would be 4.

See the explanation
Explanation:You haven't provided any figure, so I could help you in a general way providing my own figure which is attached below. In order to illustrate transformations, let's choose the third one:

How do you do this question?
Answer:
x={1,2,3}
Step-by-step explanation:
The given inequality is
[tex]1 \leqslant \frac{6x - 1}{3} \: < \: 7[/tex]
We multiply through by the LCM of 3 to get:
[tex]3\leqslant 6x - 1\: < \: 21[/tex]
We add 1 to both sides to get:
[tex]3 + 1\leqslant 6x \: < \: 21 + 1[/tex]
[tex]4\leqslant 6x \: < \: 22[/tex]
Divide through by 6 to get:
[tex] \frac{4}{6} \leqslant x \: < \: \frac{22}{6} [/tex]
This gives us:
[tex]\frac{2}{3} \leqslant x \: < \: \frac{11}{3} [/tex]
[tex]0.67 \leqslant x \: < \:3.67[/tex]
Since x is an integer, the possible values are:
x={1,2,3}
If the weight of a package is multiplied by 2/3 the result is 40 pounds. Find the weight of the package.
all you do is divide 40 by 2/3 to get the answer :D
Answer: Weight is 60
Explanation:
So lets look at what we are given:
w (weight) * 2/3 = 40 pounds
(short explanation is you times 40 by 3/2)
We want to solve for weight there are a few ways to do this but the easiest one is to times both sides of the equation by the reciprocal of 2/3. Which is 3/2. That will cancel our the 2/3 and leave only "w" on the left side.
w = 40 * 3/2
