Answer:
Rational
Step-by-step explanation:
An irrational number is a number that goes on forever, such as pi. These numbers have infinite decimals.
In contrast, a rational number is a number that can be created by dividing two other integers.
These numbers do not go on forever.
10 is a rational number because it can be created by dividing 2 other integers, and it does not go on forever.

6. Sam is buying tickets to a movie
online. The price of one ticket is $8.50.
An equation showing the total cost is
C = 8.50t +3.50 where t is the
number of tickets and $3.50 is a
convenience fee. What is the total cost
if he buys 4 tickets?
What’s the answer to this problem?
Answer: C = $37.5
Step-by-step explanation:
Given information
Price of one ticket = $8.50
Convenience fee = $3.50
Number of tickets = 4
Given expression
C = 8.50t + 3.50
Substitute the value of the ticket into the expression
C = 8.50 (4) + 3.50
Simplify by multiplication
C = 34 + 3.5
Simplify by addition
C = $37.5
Hope this helps!! :)

Answer:
a) greater than 20
b) 20 is the estimate (round all the three other numbers and add, then subtract from 80 because 20, the average, times the four meetings is 80)
c) You can check your estimate by adding all of the numbers and subtracting the answer by 80. 18 + 17 + 21 = 56. 80 - 56 = 24
24 is closer to 20 than 30, so our estimate is correct.

Select all the equivalent ratios of 8:12... 7:21 20:30 5:15 2:3 16:24 and 1:3
8:12 is 2/3 and so is 16:24, 2:3, and 20:30
Step-by-step explanation:
For example (includes simplified problem solving),
8 ÷ 4 = 2
12 ÷ 4 =3
You would want to divide the numerator and denominator by the greatest common factor (GCF)
The ratio 8:12 can be reduced to its lowest terms by dividing both terms by the GCF
Therefore 8:12 is 2:3
In Ted's class, students were asked to name their favorite sport. Football was the response of 1/8 of them. If 3 students said football, how many students are in Ted's class?
24 Students
If 1/8 of the total is 3, then the total is 3 multiplied by 8 = 24
Another way:
1/8= 12.5%
12..5%_____3
100%_____x
Cross multiplication
12.5x =3x100(300)
X=24
12.5% of 24 = 3
There are 24 students in Ted's class.
Given that;
In Ted's class, students were asked to name their favourite sport.
And, Football was the response of 1/8 of them.
Let's assume the total number of students in the class is represented by "x".
According to the information given, 1/8 of the class said football, which means (1/8) × x students named football.
We also know that 3 students said football.
So, we can set up the equation:
(1/8) × x = 3
To solve for x, we can multiply both sides of the equation by 8:
x = 3 × 8
x = 24
Therefore, there are 24 students in Ted's class.

3/8 of a scholarship fund was 1500 find the full amount of the scholarship fund
Answer:
The full scholarship fund will be 4000
Step-by-step explanation:
When doing these types of problems I like to do this.
1500 ÷ 3 = 500 (We do this because you want to find out what 1/8 is)
Since 500 is 1/8 of the part, all you have to do is multiply 500 by 8
500 × 8 = 4000
The measure of L in triangle LMN is 40°. The measure of M is 78°. What is the measure of N?
Answer: 62°
Step-by-step explanation:
Total angle in a triangle = 180°

Answer:
[tex]thank \: you[/tex]
Answer: x = 11
Step-by-step explanation:
Given
4 (x - 1) = 2 (x + 9)
Expand parentheses and apply the distributive property
4x - 4 = 2x + 18
Subtract 2x on both sides
4x - 4 - 2x = 2x + 18 - 2x
2x - 4 = 18
Add 4 on both sides
2x - 4 + 4 = 18 + 4
2x = 22
Divide 2 on both sides
2x / 2 = 22 / 2

Explanation:
Refer to the diagram below. The rectangle MATH has the diagonal MT that cuts the rectangle into two identical right triangles.
We then use the pythagorean theorem to find the length of the hypotenuse MT.
a^2 + b^2 = c^2
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
c^2 = 676
c = sqrt(676)
c = 26
Segment MT is 26 cm long.
This applies to the other diagonal AH as well.

Tom owns a landscaping business. He charges $40 for a yard cleanup, $50 to mow a lawn, and $75 to mulch a yard. On average, it takes Tom 25 minutes for a yard cleanup, 40 minutes to mow a lawn, and 2 hours to mulch a yard. Tom's clients are Mr. Hansen, Ms. Martinez, and Mrs. Johnson. . Mr. Hansen paid $125 for lawn services this week. . Tom spent more than an hour at Ms. Martinez' house this week. • Mrs. Johnson wrote Tom a check for $165 for the week. Tom made $405 from his three clients this week.
Answer:
Ms. Martinez = Tom received $115, $75 to mulch the yard and $40 for a yard cleanup.
Step-by-step explanation:
Tom made $405 for the week from his three clients
Mr. Hansen paid Tom $125
Mrs. Johnson paid Tom $165
405-165-125=115
Ms. Martinez paid Tom $115, which meant that he would have cleaned the yard ($40) and mulch the yard ($75)
The unit amount and time for each service offered by Tom can be represented as equations. The conclusion from the given parameters are:
Mr. Hansen paid $125 to mow a lawn and to mulch a yard.Mrs. Johnson paid $165 for the three servicesMs. Martinez paid $115 for a yard cleanup and to mulch a yard.Given that:
Cost
[tex]\$40 \to[/tex] Yard cleanup
[tex]\$50 \to[/tex] Mowing a lawn
[tex]\$75 \to[/tex] Mulching a yard
Time
[tex]2\ hrs \to[/tex] Yard cleanup
[tex]40\ mins \to[/tex] Mow a lawn
[tex]2\ hrs \to[/tex] Mulching a yard
[tex]Total\ Earnings = \$405[/tex]
From the question, we understand that:
[tex]Mr.\ Hansen = \$125[/tex]
Recall that:
[tex]\$50 \to[/tex] Mowing a lawn
[tex]\$75 \to[/tex] Mulching a yard
Add up:
[tex]\$50 + \$75 = 125[/tex]
This means that Mr. Hansen paid $125 to mow a lawn and to mulch a yard.
[tex]Mrs.\ Johnson= \$165[/tex]
Recall that:
[tex]\$40 \to[/tex] Yard cleanup
[tex]\$50 \to[/tex] Mowing a lawn
[tex]\$75 \to[/tex] Mulching a yard
Add up:
[tex]\$40 + \$50 + \$75 =\$165[/tex]
This means that Mrs. Johnson paid $165 for the three services
The amount paid by Ms. Martinez is calculated as follows:
[tex]Mr.\ Hansen + Mrs.\ Johnson + Ms.\ Martinez = Total\ Earnings[/tex]
Substitute known values
[tex]\$125 + \$165 + Ms.\ Martinez = \$405[/tex]
[tex]\$290 + Ms.\ Martinez = \$405[/tex]
Collect like terms
[tex]Ms.\ Martinez = \$405 - \$290[/tex]
[tex]Ms.\ Martinez = \$115[/tex]
This means that Ms. Martinez paid $115
Recall that:
[tex]\$40 \to[/tex] Yard cleanup
[tex]\$75 \to[/tex] Mulching a yard
Add up
[tex]\$40 +\$75 = \$115[/tex]
This means that Ms. Martinez paid $115 for a yard cleanup and to mulch a yard.

A Shape Question 5 options: 13 yd.² 314 yd.² 251 yd.² 503 yd.²
Answer:
What is question? surface area of upright part of cylinder is approx 314 sq yd. Surface area of entire cylinder is approx 471 sq yd, which isn't a choice.
Step-by-step explanation:
Assuming you're looking for surface area of cylinder (since answers are in sq units), you would need to find the area of the top and bottom circles, and the rectangle made by flattening out the upright part of cylinder.
Area of a circle is πr^2 so area of bottom is 25π and of both circles is 50π which equals approx 157.08 sq yd.
The rectangle formed from the upright part would have a width of 10 yds and a length equal to circumference of the circle. Since C = πd, C is approx 31.4yd. A = l x w so A = 31.4 x 10 or approx 314 sq yd.
