Shontelle has soccer practice on Thursday evening. She has a half hour before practice to work on her math homework and talk to her friends. She has 20 math skill-work questions for homework, and she wants to complete them before talking with her friends. If she can solve three math problems in four minutes when she really focuses with no distractions, how many minutes will Shontelle have left after completing her math homework to talk to her friends.
Answer:
3 1/3 minutes or 3 minutes 20 seconds
Step-by-step explanation:
We can use ratios to see how long it will take her to complete her homework
3 problems 20 problems
----------------- = --------------
4 minutes x minutes
Using cross products
3x = 4*20
3x= 80
Divide by 3
x = 80/3
x =26 2/3 minutes
She has 30 minutes
30 -26 2/3 = 3 1/3 minutes
3 minutes 20 seconds
Figure ABCD is a parallelogram. Is triangle ADB congruent to triangle CBD? Show or explain your reasoning
Answer:
yes it's congruent.
Step-by-step explanation:
in a parellelogram, all sides and angles are equal.
ΔADB is congruent to ΔCBD.
The reasoning is given below.
What is a parallelogram?A parallelogram is a quadrilateral that has two pairs of parallel sides.
In a parallelogram, opposite sides and angles are equal.
The adjacent angles add up to 180 degrees.
We have,
A parallelogram ABCD.
This means,
AD is parallel to BC
AB is parallel to CD
∠A = ∠C
BD is the diagonal of the parallelogram.
Now,
ΔADB and ΔCBD
AB = CD ( given )
∠A = ∠C (given )
∠ADB = ∠CBD ( given )
∠ABD = ∠BDC ( alternate angles )
ΔADB ≈ ΔCBD
Thus,
ΔADB is congruent to ΔCBD.

Kelsey wants to buy some new shirts at her favorite store. Each shirt costs $10 and she also wants to get a pair of shoes for $25.write an inequality. That she could use to figure out how many shirts she can buy if the most she can spend is $55 and solve
Answer:
10x + 25 less than or equal to (the sign) $55
Step-by-step explanation:
Answer:
The inequality is 10x + 25 [tex]\geq[/tex] 55
Step-by-step explanation:
This would be the possible inequality, because it says that "EACH" shirt costs 10$ meaning that Kelsey may buy multiple, which is why you would want to put 10x (for every shirt she buys they each cost 10 dollars) and PLUS she wants a pair of sneakers, so add 25 $
She has only 55$ to spend, so here MAXIMUM amount she can spend is 55$ which means, she can only buy whatever she wants for 55$ or lower.
Students make 58.5 ounces of liquid soap for a craft fair. They put the soap in 4.5 ounce bottles and sell each bottle for $5.50. How much do the students earn if they sell all the bottles of liquid soap?
Step-by-step explanation:
first you want to divide the ounces of liquid soap we have by the ounce bottles we have (58.5 / 4.5 = 13 )
so now we know we have 13 bottles of liquid soap
then you want to multiply the 13 bottles of soap by how much they sell each bottle for ( 13 x 5.50 = 71.50 )
the answer: the students would earn $71.50 if they sell all the bottles of liquid soap

Answer:
y = x - 3
Step-by-step explanation:
Answer:
Y= x-3
Step-by-step explanation:
The distance from our y values is -1.
The distance from our x values is -1.
Rise/ Run = Y/X
-1/-1 = 1 or 1/1
You would rise 1 and run 1!
You can use this strategy if you're using graph paper to eventually get the y intercept which is -3.

2x = 14 ( divide both sides by 2 )
x = 7
Give each rate in miles per hour. Round to the nearest tenth.
Dhruv jogs 8 feet per second.
I don’t know the answer please help.
The question requires changing feet per second into miles per hour
The unit rate in miles per hour is 5.5 miles per hour
8 feet = 0.00151515 miles
1 second = 0.000277778 hour
unit rate in miles per hour = number of miles / number of hours
= 0.00151515 mile / 0.000277778 hour
= 5.4545356363714 miles per hour
Approximately, 5.5 miles per hour to the nearest tenth

What is the position of C on the number line below?
Write your answer as a fraction or mixed number.
Answer:
2/5
Step-by-step explanation:
there are 5 lines starting at point 1 and ending at 2. point c is on the second line which makes it 2/5ths
The position of C on the number line below is 7/5 or 1 2/5.
What is the number line?The number line is a horizontal line where all the integers are placed at equal intervals. The number line is extended to infinity on both sides.
Also, the line segment between two integers also divided into subparts to represent the rational number.
here given in the number line there are two integers 1 and 2 in which point C is situated.
The line segment between 1 and 2 is divided into 5 parts.
every subpart in line segment between 1 and 2 will be= the length of the subpart / total number of division
= (2-1)/5= 1/5
C point is present at a distance of 2 subparts from integer 1.
So the position of C will be = 1+(2)(1/5)= 1+(2/5)= 7/5 or 1 2/5
Therefore The position of C on the number line below is 7/5 or 1 2/5.

One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 80 calories from x grams of protein and y grams of fat. 80= 4x + 9y
If there are 6 grams of fat in the snack, how many grams of protein are there? Show your reasoning.
Answer:
6,5g of protein
Step-by-step explanation:
80=4x + 9y
y=6 ( "6 grams of fat")
so: 80=4x+9.6
80-54= 4x
26/4=x
x(protein)= 6,5
Answer:
6.5 grams
Step-by-step explanation:
To find the value of x that corresponds to the given value of y, put that y-value into the equation and solve for x.
80 = 4x +9·6
26 = 4x
26/4 = x = 6.5
There are 6.5 grams of protein in the snack.
