Answer:
78
Step-by-step explanation:
5x3+4+21=78
Answer:
m<A=117°
Step-by-step explanation:
Based on the given from the problem, we know that angle A and angle B are vertical angles
Vertical angles are congruent; they have the same value.
we know that the measure of angle A is (5x-3)° and the measure of angle B is (4x+21)°
since we know they are congruent via vertical angles theorem, we can make the two values equal to each other
5x-3=4x+21
add 3 to both sides
5x=4x+24
subtract 4x from both sides
x=24
we found the value of x. However, the question asks for the value of angle A, which is (5x-3)°
we substitute our known value to find the value of angle A
m<A= (5*24-3)°
m<A=(120-3)°
m<A=117°
the measure of angle A is 117°
Hope this helps!

3. Which name does not apply to the angle pair?
A. vertical
C. supplementary
B. adjacent
D. right angles
12
Answer:
D. right angle
Step-by-step explanation:
I think D is because
right angle is a an angle of exactly 90°
*adjacent angle is two angles with a common vertex, sharing a common side and no overlap
*supplementary angle is two angle, the sum of who's measure is 180
* vertical angle is two angle who's sides form two pairs of opposite rays (straight line)
6. John predicted that gas prices would raise 3.5% in the month of
January. If gas prices actually rose from $2.25 to $2.30, what was his
percent of error? Plzzz answer
Answer:
37.5%
Step-by-step explanation:
Given data
Initila Price= $2.25
3.5% of $2.25
=3.5/100* 2.25
=0.035*2.25
=0.07875
Hence the expected new price is
=0.07875+2.25
=$2.33
The expected increase
=2.33-2.25
=$0.08
The actual increase
=2.25-2.30
=$0.05
Hence the error is
% error= Actual -Expected/Expected*100
% error= 0.05-0.08/0.08*100
% error= 0.03/0.08*100
% error=0.375*100
% error=37.5%
Hence the error is 37.5%

Answer:
[tex]\frac{9}{14} \ chance[/tex]
Step-by-step explanation:
1. Approach
Probability is a way of predicting a future outcome based on given data. In essence, the formula for finding the probability is, [tex]\frac{desired\ outcomes}{total\ outcomes}[/tex].
It is given that
- (63) paid with cash
- (22) paid with a debit card
- (13) paid with a credit card
First, add all of these numbers up to find the total number of customers. Then set up the probability, finally, simplify the fraction by diving both the numerator and denominator by a common factor.
2. Find the total number of customers
Add up all of the given customers, regardless of their payment type.;
[tex](cash)+(credit)+(debit)\\\\= 63 + 22 + 13\\\\= 98[/tex]
(98) total customers.
3. Find the probability
Now set up the probability, remember, the formula for finding the probability is,
[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]
The desired outcome is the number of customers who pay with cash = (63)
The total outcome is the number of customers who when to the business; (98)
Substitute in the numbers and simplify,
[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]
[tex]\frac{63}{98}[/tex]
Both of these numbers are divisible by (7), hence divide the fraction by (7)
[tex]\frac{9}{14}[/tex]

Answer:
see attached
Step-by-step explanation:
a) Any set of functions that has a total degree of 4 and a total number of x-intercepts of 4 will do. Shown in the first attachment are 4 linear functions. A quadratic function with two x-intercepts could replace two of the linear functions, or a cubic with 3 x-intercepts could replace 3 of the linear functions.
__
b) Again, the total degree must be 3. Since there can only be one x-intercept, the quadratic factor must have none. A possible choice is shown in the second attachment.
Ms. Rivera runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?
Answer:
88 bottles
Step-by-step explanation:
Given
[tex]Cleaner =1\ gallon[/tex]
[tex]Water =10\ gallon[/tex]
Required
Determine the number of 1-pint spray bottles used
First, we get the total gallons of the cleaner and water.
[tex]Total = Cleaner + Water[/tex]
[tex]Total = 1\ gallon + 10\ gallon[/tex]
[tex]Total = 11\ gallon[/tex]
Convert to pints:
[tex]Total = 11 * 8\ pints[/tex]
[tex]Total = 88\ pints[/tex]
To get the number of spray bottles, we divide 88 pints by the size of the pint bottle.
[tex]Number = \frac{88\ pints}{1\ pint}[/tex]
[tex]Number = \frac{88}{1}[/tex]
[tex]Number = 88[/tex]
Nicole is cooking cookies recipe calls for 5 cups of flour she has already put in three 1/3 cups how many more cups does she need to put in
Answer:
1 2/3 cups of flour
Step-by-step explanation:
Nicole is cooking cookies recipe calls for 5 cups of flour she has already put in three 1/3 cups how many more cups does she need to put in?
We solve the above question using Subtraction operation
The number of cups she still needs to put in =
5 cups - 3 1/3 cups
= 5 - 3 1/3
= 5/1 - 10/3
The Lowest Common Denominator = 3
= 15 - 10/3
= 5/3
= 1 2/3 cups of flour

Layla, Eliana and Nature each carried 10 pound bag of soil into the backyard. After putting soil in the first flower bed, Layla's bag was ⅝ full, Eliana's bag was ⅖ full, and Nature's bag was ¾ full. How many pounds of soil did they put in the first flower bed altogether?
Answer: 17.75 pounds
Step-by-step explanation:
After putting soil in the first flower bed, Layla's bag was ⅝ full. The pound of soil will be: = 5/8 × 10 = 6.25 pounds
Eliana's bag was ⅖ full. The pound of soil will be: = 2/5 × 10 = 4 pounds
Nature's bag was ¾ full. The pound of soil will be: = 3/4 × 10 = 30/4 = 7.5 pounds
The number of pounds of soil that they put in the first flower bed altogether will be:
= 6.25 + 4 + 7.5
= 17.75 pounds

Which trigonometric function would you use to find “h”, the height of the tree?
Answer: C
Answer:
C
Step-by-step explanation:
Sine: Opposite / Hypotenuse
Cosine: Adjacent / Hypotenuse
Tangent: Opposite / Adjacent
75 = The adjacent of 40
H = The opposite of 40
Tan40 = 75 / h
H = 75Tan40
H ≈ 62.93
The trigonometric function which will be used to determine the height of the tree when the base is 75 ft. is tan(40)
What is trigonometric function?The trigonometric function are the ratio of the sides of the right angled triangle. The functions are sine, cos, tan , cot, cosecant, secant.
How to find the height of the tree?We can easily see that the base is 75 ft. and the height of the tree is h So the height of the tree can be found with the help of tangent function.
tan(40)=h/75
0.84=h/75
h=63 ft.
Hence the height of the tree is 63 ft.

Step-by-step explanation:
Round 1 of a tennis tournament starts with 64 players. After each round, half of the players have lost and are eliminated from the tournament. Therefore, in round 2 there are 32 and in round 3 there are 16 players and so on. Can this relationship be modeled by a linear function? Provide evidence to support your claim.
Answer:
It can not be modeled by a linear function
Step-by-step explanation:
The given parameters can be represented as:
[tex](x_1,y_1) = (1,64)[/tex]
[tex](x_2,y_2) = (2,32)[/tex]
[tex](x_3,y_3) = (3,16)[/tex]
Where: x = rounds and y = players
Required:
Determine if it can be represented by a linear function
To do this, we simply calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
and
[tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex]
Using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex], we have:
[tex]m = \frac{32 - 64}{2 - 1}[/tex]
[tex]m = \frac{-32}{ 1}[/tex]
[tex]m = -32[/tex]
Using [tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex], we have:
[tex]m = \frac{16 - 32}{3 - 2}[/tex]
[tex]m = \frac{-16}{1}[/tex]
[tex]m = -16[/tex]
Since both slopes are not the same, the relationship be modeled by a linear function
