Cierra had $9 to spend on 3 new
pencils for school. After buying
the pencils she had $3.85 left. How
much did she spend on each pencil?
Write an equation to represent
this situation and then solve.
Answer:
i don't know what the equation would be but hope this helped! 1.72 for each pencil
Step-by-step explanation:
9 - 3.85 = 5.15
5.15/3 = 1.72 for each pencil
Answer:
About $1.72 per pencil
Step-by-step explanation:
1. 9-3.85 = 5.15
2. 5.15/3 = 1.71 2/3 (1.7166666667)
3. $1.72/pencil
Solve for x. 4(x+1)= -3x-10
Answer:
4x+4=-3x-10
4x+3x=-10-4
x= -14
Step-by-step explanation:
Answer:
x = -2
Step-by-step explanation:
P.E.M.D.A.S
4(x + 1) = 4x+4
now we have 4x + 4 = -3x - 10.
now we can combine like terms which are x
4x and -3x, to combine like terms we can either subtract 4x on both sides or -3x on both sides, but lets do 4x.
now we have this
4x + 4 = -3x - 10.
-4x -4x
= 4 = -7x - 10
now we can isolate x by its self so we have to add 10 on both sides
4 = -7x - 10
+10 +10
and we get
14 = -7x
now we can divide -7 to get x by its self
14/-7 = -7/x
we get for our final answer
x = -2

Using the diagram, determine whether the angles are vertical angles, a linear pair, or neither. (Image is included)
Answer:
1.linear pair
2. neither
3. vertical
4. neither
5. vertical
6. neither
7. linear pair
8. neither
Step-by-step explanation:
the answers are starting from up to down, not side to side
We have the definitions of the Adjacent angles, linear angles, vertical angles.
Two angles are considered to be adjacent angles when they share a common vertex, a common side, but no common interior pointsWhen two lines intersect each other at a single point, linear pair of angles are formed. If the angles so formed are adjacent to each other after the intersection of the two lines, the angles are said to be linear.Two angles are said to be vertical angles when their sides form two pairs of opposite rays (straight lines).So, from the figure we see that
<1 and <2 are linear pair <2 and <4 are neither <6 and <8 are vertical <11 and <1 are neither<1 and <3 are vertical <4 and <5 are neither <8 and <9 are linear pair <10 and <7 are neitherLearn more:https://brainly.com/question/3182415
Jerrod’s family drove 1,778 miles from Denver, Colorado, to New York City. They averaged 61.7 miles per hour on the trip. Which is the best estimate of the number of hours the family drove?
Given parameters:
Distance traveled = 1778miles
Average speed = 61.7 miles per hour
Unknown:
Time taken for the travel = ?
Speed is a physical quantity. It is the rate of change of distance with time.
It can be mathematically expressed as;
Speed = [tex]\frac{distance}{time taken}[/tex]
The unknown here is the time taken;
Substitute the parameters and solve for it;
61.7 = [tex]\frac{1778}{ time taken}[/tex]
time taken = [tex]\frac{1778}{61.7}[/tex] = 28.8hrs
The time taken is 28.8hrs
Answer:
the answer for this would be 30 hours.

Can you conclude with a high degree of confidence that the population means for Iowa and New Jersey students are different? A. Because of the extremely low p-value, we cannot reject the null hypothesis with a very high degree of confidence. Hence, the population means for Iowa and New Jersey students are not different. B. Because of the extremely high p-value, we can reject the null hypothesis with a very high degree of confidence. Hence, the population means for Iowa and New Jersey students are different. C. Because of the extremely low p-value, we can reject the null hypothesis with a very high degree of confidence. Hence, the population means for Iowa and New Jersey students are different. D. Because of the extremely high p-value, we cannot reject the null hypothesis with a very high degree of confidence. Hence, the population means for Iowa and New Jersey students are not different.
Complete Question
The complete question is shown on the first uploaded image
Answer:
Option A is correct
Step-by-step explanation:
From the question we are told that
The 95% confidence interval of the mean score of all New Jersey third graders is (58.957 , 63.043)
The sample size is n = 184
The sample average is [tex]\mu = 65 \ points[/tex]
The standard deviation is [tex]\sigma = 13 \ points[/tex]
The 90% confidence interval for the difference in mean score between lowa and New Jersey is (-6.33 , -1.67 )
The p-value is [tex]p-value = 0.0048[/tex]
Generally given that the p-values is very low compared to the level of significance (100 -90 = 10% = 0.10 ) we can reject the null hypothesis which is usually a claim that the means of the population are the same )
Hence the population means are different .

The table shows expressions to represent the number of students involved in different activities. The number of students involved in sports and student council is equal to the number of students involved in band and drama club. Model the situation with an equation. Select the correct expression for each box. Then solve the equation.
Answer:
6n + 7 = 7n
Step-by-step explanation:
Number of students involved in sports = 5n + 7
Number of students involved in student council = n
Number of students involved in sports and student council = (5n + 7) + n = 5n + 7 + n = 6n + 7
Number of students involved in band = 3n - 2
Number of students involved in drama club = 2(2n + 1)
Number of students involved in band and drama club = (3n - 2) + 2(2n + 1) = 3n - 2 + 4n + 2 = 7n
Equation to model number of students involved in sports and student council which equal number of students involved in band and drama club:
6n + 7 = 7n

. Steve drove for 812 hours at 72 miles per hour. How much distance did he travel?
Answer:
58464
Step-by-step explanation:
Multiply the two numbers
Answer:
If Steve drives for 812 hours at 72 miles per hour, he drives 58,464 miles in total.(Side Note: if you mean 8 1/2 hours then it's 612 miles
Step-by-step explanation:
To find distance dealing with time and speed, we can use the formula d=rt.
D= Distance
R= Speed
T= Time
Now we plug in our values! D=72 × 812 and we get D= 58,464 miles or if you meant 8 1/2 hours, then it's 612 miles

Planet Earth has a mass of 5.9726 × 10 24 kilograms. And although 70% of the Earth's surface is made of water, the water's mass is only 5 × 10 -4 percent of the Earth's total mass. Use scientific notation to estimate the mass of the planet's water. In your final answer, include all of your estimates and calculations.
Answer:
i don't it is correct or not........
Step-by-step explanation:
The Mass of Earth = 5.9742 × 1024 kilograms == == The Earth is (As of May 2000) is thought to be approximately 5.972 sextillion (5,972,000,000,000,000,000,000) metric tons.
A metric ton is a thousand kilograms, or 2,204.62 pounds.
Approximately 6,000,000,000,000,000,000,000,000 (6x1024) kilograms.
Answer:
Mass on water on earth is 29.5×10^20 kg approximately.
Step-by-step explanation:
Mass of earth= 5.9726 × 10^ 24 kg
water's mass is only 5 × 10 -4 percent of the Earth's total mass.
so mass of water = 5.9726×10^24 kg×5×10^-4=29.8603×10^20kg approximately

Evaluate the following: −3 − (−8).
Answer:
5
Step-by-step explanation:
When you have a negative next to a negative, you can turn it into a positive. For example the -(-8) would now be +8. This is called the airplane strategy because it forms a airplane if you flip you sheet of paper or your device.
From here, we have -3+8.
Now we subtract since each value has a different sign and we get +5.
Hope this helps!! :)

Find the mass of the object if it has a volume of 20 mL and a density of 3 g/mL.
Answer:
60 g
Step-by-step explanation:
Use the density formula, D = m/v, where m is the mass and v is volume
Plug in the volume and density, then solve for the mass:
D = m/v
3 = m/20
60 = m
So, the mass is 60 g
Volume of object = 20 mL
Density of object = 3 g/mL
To Find :We have to find mass of the object[tex].[/tex]
Solution :★ Density is defined as the mass of object per unit volume.
It is a scar quantity having only magnitude.
Mathematically, ρ = M/V
ρ denotes densityM denotes massV denotes volumeBy substituting the values, we get
⭆ 3 = M/20
⭆ M = 3 × 20
⭆ M = 60 g
∴ Mass of the object is 60g.
