Please!!! Help me plzz
Answer:
i thinks or might be the correct
Answer:
The correct answer is [tex]\frac{or}{and} \\[/tex].
Step-by-step explanation:
Part 1: The sign "<" means "less than." Therefore, "or" makes the most sense because there is only one option if you use this sign: the number on the left has to be smaller than the number on the right.
Part 2: The sign [tex]\leq[/tex] means "less than or equal to." Therefore, "and" makes the most sense because there are two options if you use this sign: the number on the left can be either smaller than or equal to the number on the right.
Therefore, the correct answer is [tex]\frac{or}{and} \\[/tex].

The ratio of boys to girls in Mr. Johnson’s class is 3:5. If there are 32 students in his class, how many of these students are girls? Write equation and solve.
Answer:
12:20
Step-by-step explanation:
3 : 5 = 3x : 5x = 32
3x + 5x = 8x = 32
x = 32/8 = 4
3x = 3x4 = 12
5x = 5x4 = 20
so there are 12 boys and 20 girls

13 is no more than 5 less than a number. What is the minimum value of the number?
Answer:
18 is the minimum value.
Step-by-step explanation:
Set up an equation:
13 [tex]\leq[/tex] x - 5
Add 5 on both sides to isolate x:
(13) + 5 [tex]\leq[/tex] (x - 5) + 5
18 [tex]\leq[/tex] x
X can be equal to or greater than 18 so the minimum value of the number is 18.

Your job is to sort and sack marbles for sale a bag contains 55 marbles some red and some green if there are 11 red marbles what is the ratio of red to green marbles?
Answer:
1:4
Step-by-step explanation:
There are only two colours available, red and green. We know that there are 11 red marbles and 55 marbles altogether, so the number of green marbles must be 55 - 11, or 44. That means that the ratio of red to green marbles is 11:44, or 1:4.

A linear function is graphed on the grid.
What is the rate of change of y with respect to x?
Check the picture below.
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
to get the slope of any straight line, we simply need two points off of it, let's use those in the picture below.
[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{-3}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-3}-\stackrel{y1}{3}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{0}}} \implies \cfrac{-6}{2}\implies \LARGE \begin{array}{llll} -3 \end{array}[/tex]

The price of silver has increased by 25% per year from 2000. In the year 2000,Harry bought a silver bowl for $170. Write a function F(x) that can be used to represent the price of the bowl in x years after 2000
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The price of silver has increased by 25% per year from 2000. In the year 2000, Harry bought a silver bowl for $170.
To calculate the price of the silver bowl after x years, we need to use the following formula:
F(x)= PV*(1+g)^x
F(x)= future value
PV= present value
g= growth rate
x= number of years
For example, we determine the value of the coin after 10 years:
F(x)= 170*(1.25^10)
F(x)= $1,583.25
Answer:
F(x)= 170*(1.25^10)
F(x)= $1,583.25

Step-by-step explanation:
please mark me brainliest
Answer:
n = -1
Step-by-step explanation:

7n = -7
n = -1
Benny wants to buy a new video game that costs $49.95. He already saved $24.65, and his aunt gave him $15 for mowing her lawn. How much more money does Benny need to buy the video game?
Answer:
$10.30
Step-by-step explanation:
X = 49.95 - (24.65 + 15)
x = 49.95 - 39.65
x = 10.30
Which of the following does not have the same value as the whole number 4?
3 5/5
1/4
4/1
3 4/4
Answer:
B
Step-by-step explanation:
3 5/5 = 4 because 5/5 is equal to 1, and 3+1 = 4.
1/4 is not equal to 4 because it is equal to 0.25
4/1 = 4 because it is an identity
3 4/4 = 4 because 4/4 is equal to 1, and 3+1 = 4
A tile pattern has 5 tiles in figure 0 and adds 7 tiles in each figure, write a linear equation that represents this pattern
Answer:
The equation is:
y = 7x + 5
Step-by-step explanation:
Given
Figure 0 = 5 tiles
Figure 1 = 5+7 = 12 tiles
Given that it adds 7 titles in each figure. Thus, the rate of change = 7 tiles
Thus, the equation is:
y = 7x + 5
Here
7 is the rate change or slope of the equation.VERIFICATION:
setting x = 0 to determine the tiles in figure 0
y = 7x + 5
y = 7(0) + 5
y = 5
Thus, the figure 0 has 5 tiles
setting x = 1 to determine the tiles in figure 1
y = 7x + 5
y = 7(1) + 5
y = 7 + 5
y = 12
Thus, the figure 0 has 12 tiles (5 plus 7 added)

In the first round of a card game, Niki scored 20 points. Then, she lost 10 points on one turn and an additional 25 points on her final turn. Part A Choose the number line that shows the change in Niki's score.
Full question :
Nthe first round of a card game, niki scored 20 points. then, she lost 10 points on one turn and an additional 25 points on her final turn. part a choose the number line that shows the change in niki’s score.
a. number line from -20 to 20. start at -20. count up by 5. 3 arrows are shown above the number line. 1st from 0 to -20, 2nd from -20 to -10 and 3rd from -10 to 15.
b. number line from -20 to 20. start at -20. count up by 5. 3 arrows are shown above the number line. 1st from 20 to 0, 2nd from 0 to -10 and 3rd from -10 to 15.
c. number line from -20 to 20. start at -20. count up by 5. 3 arrows are shown above the number line. 1st from 0 to 20, 2nd from 20 to -5 and 3rd from -5 to 5.
d. number line from -20 to 20. start at -20. count up by 5. 3 arrows are shown above the number line. 1st from 0 to 20, 2nd from 20 to 10 and 3rd from 10 to -15.
part b what is niki’s final score? enter your answer in the box. points
Answer:
d. number line from -20 to 20. start at -20. count up by 5. 3 arrows are shown above the number line. 1st from 0 to 20, 2nd from 20 to 10 and 3rd from 10 to -15.
Step-by-step explanation:
The number line given run from -20 to +20 and so we record Niki's losses and wins using the negative numbers and positive numbers respectively. If Niki wins(scores 20 points) we add, that is a positive number on the number line. If Niki loses(loses 10 and 25 points) we subtract from her positive number using the negative values(points missed) on the number line. If we do this, Niki's value on the number line ends up at -15
To get Niki's final score, we calculate hence
+20-10-25 = -15 points
