Step-by-step explanation:
Lily drives 90 miles in 2 hours. If she drives at the same rate, how far does lily travel in each of the following time intervals: 1 hour, 1/2 hour, and 3 hours? Please solve in at least two different ways. You could make a bar model, double number line, ratio table, or graph
How far does she drive in 3 hours
Answer:
1 hour= 45 miles
1/2 hour=22.5 miles
3 hours= 135
Step-by-step explanation:
just work out one hour by halving 90 miles which is 45. Then work out the rest by halving again and multiplying by 3.
Answer:
1st way:
90/2=45
1 hour = 45 miles
45/2=22.5
0.5 hour = 22.5 miles
45+22.5=67.5
1.5 hour = 67.5 miles
67.5x2=135
3 hours = 135 miles
2nd way:
90 miles - 2 hours
1 hour - 60 minutes
60x2=120
90/120=0.75
1 minute - 0.75 miles
0.75x60=45
1 hour = 45 miles
60:2=30
60+30=90
0.75x90=67.5
1.5 hour = 67.5 miles
60x3=180
0.75x180=135
3 hours = 135 miles

Find the measure of the arc. Please help!
Answer:
The value of mEFD = 214°
Step-by-step explanation:
Given that the measure of the degree of one of the central angles of an inner circle is 146°.
We know that sum of all central angles is 360°.
In other words, in our case
mEFD + 146° = 360°
Thus, we can determine the mEFD using the equation
mEFD + 146° = 360°
so subtracting 146° to both sides
mEFD + 146° - 146° = 360° - 146°
mEFD = 214°
Therefore, the value of mEFD = 214°

Step-by-step explanation:
Greg buys apples, bananas, and kiwis from a fruit stand each week. The first week he pays $3.19 for 2 apples, 3 bananas, and 2 kiwis. The second week he pays $4.12 for 3 apples, 4 bananas, and 2 kiwis. The third week he pays $3.01 for 1 apple, 1 banana, and 4 kiwis. Choose the system of equations that can be used to solve for the number of apples,a, the number of bananas,b, and the number of kiwis,k.
Answer:
Step-by-step explanation:
2a+3b+2k= $3.19
3a+4b+2k=$4.12
1a+1b+4k=$3.01
The system of equation that can be used to solve these scenario are 2a + 3b + 2k = 3.19, 0a + 4b + 2k = 4.12 and 1a + 1b + 4k = 3.01.
What is a linear equation?A linear equation consist of variables and constant sperated by arithmetic operations which has highest degree of 1.
We know that a system of equations is formed when we have two or more than two linear equations in two or more than two variables and a system of equations is consistent when the number of variables is equal to or less than the number of equations.
Given in this questin is 3 variables Applles(a). Bananas(b) and Kiwis(k) and we can form three equations in three variables they are,
2a + 3b + 2k = 3.19...(i)
0a + 4b + 2k = 4.12...(ii)
1a + 1b + 4k = 3.01...(iii)
We can solve this system of equation by first multiplying eqn(iii) by 2 and then subtracting it from eqn(i) to eliminate variable 'a' and then equating with eqn(ii) to eliminate variable 'b' or 'k'

What is the measure of
A. 60°
B. 80°
C. 110°
D. 120°
Answer:
A. 60 degrees
Step-by-step explanation:
The sum of the abgles in a triangle is 180°. We are already given 96° and 24°.
so we will subtract the given values from 180 to find the third angle
180-(96+24)=180-120=60°
The answer is A. 60°

The ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3.
If there are 48 paintbrushes, how many bottles of paint are there?
Answer:
Well, 48 divided by 8 is 6. And 6 times 3 is 18. So I belive that there would be 18 bottles of paint.
Step-by-step explanation:
The number of bottles of paintbrushes is 18.
What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A ratio shows how often one number is contained in another.
For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.
Given that the ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3. If there are 48 paintbrushes.
The number of the bottles will be calculated as:-
P / B = 8 / 3
3P = 8B
3 x 48 = 8B
B = 3 x 6
B = 18
Therefore, the number of bottles of paintbrushes is 18.

The first term is 8 Each term is 4 more than double the previous term.
Answer:
8*2^(n-1)
Step-by-step explanation:
This is a geometric sequence since we multiply from the previous term.
a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.
The first term is 8, so we have
a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)

45 and a third divided by one sixth and then write a sentence to show work and create multiplication of number
Answer:
272
Step-by-step explanation:
45 and a third = 45 1/3
one sixth = 1/6
hence:
45 and a third divided by one sixth =
= 45 1/3 ÷ 1/6
= 136/3 ÷ 1/6
We convert to multiplication by converting 1/6 to its reciprocal which is 6/1
Hence:
= 136/3 ×6/1
= 272
Ulani is constructing a triangle that has sides measuring 12 cm and 28 cm. Which measurements could be the length of the third side? Select two options
Answer:
The sides can be 38 and 24.
Step-by-step explanation:
Consider the provided information.
The given options are: a) 15, b) 24, c)38, d)41, E)53
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
Here a=12 and b=28 we need to find c
The sum of 12 and 28 is 40.
So, It means the side can not be 41 and 53 as it is greater than 40.
Now let the third side is 15.
Then the sides are 12, 28 and 15
The sum of two smaller sides: 12+15=27
But 27 is less than 28.
So the side can't be 15.
Now let the third side is 24.
Then the sides are 12, 28 and 24
The sum of two smaller sides: 12+24=36
But 36 is greater than 28.
So the side can be 24.
Now let the third side is 38.
Then the sides are 12, 28 and 38
The sum of two smaller sides: 12+28=40
But 40 is greater than 38.
So the side can be 38.
Hence, the sides can be 38 and 24.
