Answer:
56°
Step-by-step explanation:
180 = 40 + (2x) + (3x)
180 - 40 = 40 + 5x - 40
140/5 = 5x/5
x = 28
2(28)
= 56
Answer:
m∠A = 56°
Step-by-step explanation:
A triangle contains 180°. So
180 - 40 = 140
2x + 3x = 140
5x = 140
x = 28
Now, plug in the value for x.
2(28) = 56
Check your work.
40 + 56 + 84 = 180
A student has taken three math tests so far this semester. His scores for the first three tests were 65, 67, and 69. Suppose his test scores continue to improve at the same rate. What will be his grade on the sixth (and final) test? What will be his total score for all six tests?
Answer:
75
Step-by-step explanation:
Scores for his first tests were 65, 67, 69.
Rate of change: +2
y=2x+63; 63 is the 0th test he took, his first test was 65, so 65-2=63. 2x is the rate of change, his tests scores increase by 2 each time.
x=6, 6th test score
y=2(6)+63
y=12+63
y=75
So, on his 6th test he will get a score of 75
Mr. Garvey is almost finished working on his rectangular patio. He has ordered enough patio stones to cover an area of 600ft2. He knows that his yard is 30ft wide. He also remembers that there is an equation for areas of a rectangle: FASTTTTT
Answer:
20 ft
Step-by-step explanation:
Area of a rectangle = length x width
600 ft^2 = 30 ft x length
length = 600 / 30
= 20 ft

Answer:81
Step-by-step explanation: calculator cause I got Mind jambled-
Answer:
[tex]81[/tex]
Step-by-step explanation:
6 + 1 + 7 = 14
8 + 9 + 5 = 22
4 + 6 + 7 = 17
7 + 7 + 7 + 7 = 21.
now add all of the results together.
14 + 22 + 17 + 21 = 81
hence, the answer is 81.
A recipe calls for 1/2 of a teaspoon of sugar for every 15 cookies. If you are going to make 75 cookies for a party, how many teaspoon of sugar will you use.
Answer:
2.5 teaspoons
Step-by-step explanation:
75/15 = 5
1/2 · 5 = 2.5
Answer:
2.5 teaspoons of sugar
Step-by-step explanation:
[tex]\frac{15}{0.5} =\frac{75}{y}[/tex]
Cross multiply.
15 × y = 0.5 × 75
15y = 37.5
15y ÷ 15 = 37.5 ÷ 15
y = 2.5

Suppose you take 340 mg of a certain medication.
The amount of medication in your body decreases by 32% per hour.
Write a function for M(h), the number of milligrams of the medication in your body after h hours
Answer:
m= 340 × 0.68h
Step-by-step explanation:
Given that
You take 340 mg of the certain medication
And, the amount of medication would be reduced by 32% per hour
So we need to the find the function for M(h)
Here M denotes the milligrams
And, the h denotes the hours
So, the function would be
m = 340 × (1 - 0.32)h
m= 340 × 0.68h
The same would be considered and relevant

Substitute the values of a = 7 and b = 11. What expression do you get when you substitute these two values? 67 + 311 6 ( 7 ) + 3 ( 11 ) 6 ( 7 ) - 3 ( 11 ) 7 ( 7a) + 3 ( 11b)
Answer:
[tex]6(7) + 7(11)[/tex]
Step-by-step explanation:
Given
The expression is:
[tex]6a + 7b[/tex]
[tex]a = 7[/tex]
[tex]b = 11[/tex]
Required
The corresponding expression when the values are substituted for the variables
We have: [tex]6a + 7b[/tex]
Substitute [tex]a = 7[/tex]
So, the expression becomes:
[tex]6(7) + 7b[/tex]
Substitute [tex]b = 11[/tex]
So, the expression becomes:
[tex]6(7) + 7(11)[/tex]

Mara carried water bottles to the field to share with her team at halftime. The water bottles weighed a total of 60x2 + 48x + 24 ounces.
Which factorization could represent the number of water bottles and weight of each water bottle?
6(10x2 + 8x + 2)
12(5x2 + 4x + 2)
6x(10x2 + 8x + 2)
12x(5x2 + 4x + 2)
Answer: 12(5x2 + 4x + 2) is correct answer
Step-by-step explanation:
60x2 + 48x + 24
if we take 6 as a common factor
6(10x^2+8x+4) so first option is not true
if we take 12 as a common factor
12(5x2 + 4x + 2)
6x & 12x can not be taken as common factor..
so the correct option is 2nd one..
the temperature in november was less than 55 degrees every day which inequality shows the temperature in november
Answer:
a. x < 55
Step-by-step explanation:
We know that the temperature in November was less than 55° every single day, we are then asked to find which inequality out of the four given shows the temperature in November.
To do so, take the most crucial information, "the temperature in November was less than 55° every single day." The words "less than" makes us know that we will be using the sign "<". Looking at the answers, we see only one that uses it, and that is a.
Therefore a is the correct answer.
The probability of a chance event is 0.5, it is __________ to happen when compared to a chance event with a probability of 1.
Answer: less likely
Step-by-step explanation:
Given
The probability of an event is 0.5
The value of probability always lies between 0 and 1. 0 represents that event will not while 1 represents the certainty of the event.
When 0.5 is compared with 1, it is less likely to happen i.e. chances of this event to occur are less compared to the a event with probability of 1.

Kayla is financing $168,125 to purchase a house. She obtained a 25/8 balloon mortgage at 3.85%. What will her balloon payment be
Answer:
$130,626.56
Step-by-step explanation:
Kayla is financing $168,125 to purchase a house. She obtained a 25/8 balloon mortgage at 3.85%. What will her balloon payment be?
We are told that: She obtained a 25/8 balloon mortgage at 3.85%
This means the loan is amortized for 25 years and she would be monthly payment for 8 years before making the balloon payment.
Step 1
We find Monthly payments
Pmt = (A * i * (1 + i)ⁿ) / ((1 + i)ⁿ - 1)
Where:
Pmt - monthly payment;
A - Loan amount = $168,125
i - periodic interest rate = 3.85% = 0.0385
and
n - number of periods =
1 year = 12 months
8 years = x
x = 8 × 12 months = 96 months
n = 96 months
Pmt = (168,125 × 0.0385 * (1 + 0.0385)⁹⁶) / ((1 + 0.0385)⁹⁶- 1)
Pmt = $873.56
Step 2
When we find the monthly payment, we can compute the balance due after the term of a balloon loan.
B = (A * (1 + i)ⁿᵇ) - Pmt / i * ((1 + i)ⁿᵇ - 1)
Where:
B - Balloon payment
nb - Number of balloon loan periods =
Pmt - Monthly payment = $873.56
B = (168,125 × (1 + 0.0385)⁹⁶) - 873.56 / 0.0385 × ((1 + 0.0385)⁹⁶- 1)
B = $130,626.56
3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers
Answer:
2, 5, 8
Step-by-step explanation:
For starters, let us assume that the numbers are x-d, x, and x+d.
Where d is the common difference between terms.
This mean that we can say, from the question
x-d + x + x+d = 15
3x = 15,
x = 5,
This means that the terms are 5, 5-d and 5+d.
On the other hand,
(5-d) * 5 * (5+d) = 80
(5-d) * (5+d) = 80/5
(5-d) * (5+d) = 16
25 - d² = 16
d² = 9
d = + or - 3.
Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.
