Let's solve this step by step:
The first digit has 9 choices --> 1 through 9The second digit has 10 choices --> 0 through 9*the first digit cannot have '0' as its first digit since it would make the
number one-digit
Total Choice: 9 choices * 10 choices = 90 choices

the sum of 3x and 1 is greater than-5 and less than or equal to 10
Answer:
x is greater than -2 and less than or equal to 3
Step-by-step explanation:
so the 3x + 1 is greater than -5
so 3x is greater than -6
we divide both sides by 3
then we find out that x is greater than -2
we also know that 3x + 1 is less than or equal to 10
so 3x is less than or equal to 9
we divide both sides by 3
then we find out that x is less or equal to 3
so we can say that x is greater than -2 and less than or equal to 3

Answer:
There are 5 red Marbles
Step-by-step explanation:
Alright so since the probability of drawing a red marble is
P(Red) = #Outcomes of Red/#Outcomes in Sample space
The sample Space is 40 marbles.
The probability of drawing red was said to be [tex]\frac{1}{8}[/tex]
P(Red) = [tex]\frac{1}{8}[/tex]

Amir is expecting to receive at least $50 from his grandparents for his birthday. He plans on using all of the money to buy new clothes for summer. He would like a new pair of sandals that cost $26.50 and new shirts that cost $8 a piece. Write an inequality to represent the number of new shirts he can buy in terms of the sandals and the amount of money he will receive.
The inequality that models the situation is given by:
[tex]8n \leq 23.5 \rightarrow n \leq 2.9375[/tex]
How does Amir plans to spend his $50?He plans to spend it as follows:
With a new pair of sandals, costing $26.50.With n new shirts, each costing $8.Hence, his total spending is given by:
T = 26.50 + 8n.

In the figure; Triangle ABC is isosceles with BC=AC . If ∠A = 70, find the values of x and y . Give reasons for your answer.
Captionless Image
Answer:
∠B = 70 and ∠C = 40
Step-by-step explanation:
The image is not loading for me but with isosceles triangles there will two angles that are the same and one different angle.
All the angles will add up to equal 180 degrees.
In this case the different angle would angle C as the two same lines meet at that point.
From this you can that angle A and B are the same, both 70, so angle C would be:
180 (all the angles of a triangle added together) - 70 - 70 = 40
I'm assuming that x and y are angles B and C as they are not stated so they would be: ∠B = 70 and ∠C = 40.

Step-by-step explanation:
1.
1% of 500 is 5 so multiply 5 by 8 for one year. which is 40 so multiply that by 2.
1% of 500 = 5
5 × 8 = 40
40 × 2 = 80
2.
1% of 1000 = 10
10 × 5 = 50
50 × 3 = 150
3.
12 months = 6%
6/12 = 1 month
0.5 = 1 month
0.5 × 9 = 4.5 (the amount of interest for 9 months.)
800 × 4.5% = 36
4.
12 months = 7%
7/12 = 1 month ( i'll leave this in fraction form because of the decimal points.)
7/12 x 8 = 4.666667 or 4.7 rounded.
1200 × 4.7% = 56.40

Uncle Jack cut 3.8 m of a 8 m-long wood to make a shelf. What percent of the wood did Uncle Jack cut to make the shelf?
Answer:
47.5%
Step-by-step explanation:
3.8/8.0 x 100
= 47.5%
Uncle Jack used 47.50 percent of the wood he cut to create the shelf.
What is the percentage?The percentage can be described as a quarter of 100. The phrase % decodes to one hundred percent. It is represented by the symbol '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Uncle Jack cut 3.8 m of 8 m-long wood to make a shelf.
Then the percentage of the wood that Uncle Jack cut to make the shelf will be given as,
P = (3.8 / 8) x 100
P = 0.475 x 100
P = 47.50%
The percentage of the wood that Uncle Jack cut to make the shelf will be 47.50.

B. Move up 1 and right 2.
C. Move up 4 and right 2.
D. Move down 2 and left 1.
E. Move down 1 and left 2.
Answer:
A, move up 2 and right 1
Step-by-step explanation:
If you follow this rule, you can see that all those consistent dotted points will simplify to the same ratios.
Answer:
A, C, D
Step-by-step explanation:
First, we have to create a line based on the data.
Now, we know that the equation of the line is as follows
y = 2x
meaning that whenever we go a certain amount of units to the right or left, we move double that amount up or down
Now, A is equivalent to the Slope, so nthat is automatically equivalent.
C and D are both placed on the line, so they are correct
Another way to think about this is using fractions
x = 1/2 y
For A,
1 = 1/2(2)
For C,
2 = 1/2(4)
For D,
-1 = 1/2(-2)

(-1, 8)
(8, 1)
(-1, -8)
(1, -8)
Answer:
(1, -8)
Step-by-step explanation:
In this case, we are reflecting. Since we are reflecting over the x axis, the only thing that will change will be the y.
----------------------------------------------------------------------------------------------------------
The x is staying the same because it is not moving. The y, however, is changing sides.
----------------------------------------------------------------------------------------------------------
Since the y is positive in its original spot, when you reflect over the x axis, you will have a negative y value, which is why it is a -8.

Sunshine Rental rents a motorcycle at a daily rate of $57.99 plus 48 cents per mile. City Rentals
rents the same motorcycle at $58.95 plus 46 cents per mile. For what mileage is the cost the same?
Answer:
48 miles
Step-by-step explanation:
To find the mileage when both cost the same, first form two equations for the total cost for each rental place.
Let the mileage be m.
Sunshine Rental
Daily rate= $57.99
Total cost= $(57.99 +0.48m)
City Rentals
Daily rate= $58.95
Total cost= $(58.95 +0.46m)
Let's equate both equations together.
When both costs the same,
57.99 +0.48m= 58.95 +0.46m
0.48m -0.46m= 58.95 -57.99
0.02m= 0.96
Solve for m:
m= 0.96 ÷0.02
m= 48
The cost is the same at 48 miles.
