Note that the angle measures are rounded to the nearest degree.
Answer:
m∠C=28°, m∠A=62°, AC=34.1 units
Step-by-step explanation:
Given In ΔABC, m∠B = 90°, , and AB = 16 units. we have to find m∠A, m∠C, and AC.
As,
⇒
By angle sum property of triangle,
m∠A+m∠B+m∠C=180°
⇒ m∠A+90°+28°=180°
⇒ m∠A=62°
Now, we have to find the length of AC
⇒
The length of AC is 34.1 units
Lola gets two 20-minute breaks at work each day. She works 5 days a week. How much time does she spend on break each week?
Group of answer choices
Answer:
200 minutes / 3 hours & 20 minutes.
Step-by-step explanation:
This is quite simple.
First, since we know that Lola takes two 20 minute breaks at work each day, let's multiply 20 and 2.
20 × 2 = 40
This means she is on break for a total of 40 minutes each day.
Finally, let's take that 40 and multiply it by 5.
40 × 5 = 200
This means she spend 200 minutes (3 hours & 20 mins) on break each week.
Select each pair of expressions that are equivalent. 3x + 14 – x + 112 and 4x + 134 2 + 6x and 2(3x + 1) 3(x + 1) – (1 – x) and 2x + 3 3x and 4(x + 1) – x – 4 5.5 + 2.2x + 3.8x – 4.1 and 1.4 + 6x
Answer:
Options (2), (4) and (5)
Step-by-step explanation:
Option 1
(3x + 14 - x + 112) and (4x + 134)
Since, (3x + 14 - x + 112) = (3x - x) + (12 + 112)
= 2x + 124
Therefore, (3x + 14 - x + 112) ≠ (4x + 134) [Not equivalent]
Option 2
(2 + 6x) and 2(3x + 1)
2(3x + 1) = (6x + 2)
Therefore, (2 + 6x) = (6x + 2) [Equivalent]
Option 3
3(x + 1) - (1 - x) and (2x + 3)
Since, 3(x + 1) - (1 - x) = 3x + 3 + x - 1
= (3x + x) + (3 - 1)
= 4x + 2
Therefore, (2x + 3) ≠ (4x + 2) [Not equivalent]
Option 4
3x and 4(x + 1) - x - 4
Since, [4(x + 1) - x - 4] = 4x + 4 - x - 4
= (4x - x) + (4 - 4)
= 3x
Therefore, 3x = [4(x + 1) - x - 4] [Equivalent]
Option 5
(5.5 + 2.2x + 3.8x - 4.1) and (1.4 + 6x)
Since, (5.5 + 2.2x + 3.8x - 4.1) = (2.2x + 3.8x) + (5.5 - 4.1)
= (6x + 1.4)
Therefore, (1.4 + 6x) = (6x + 1.4) [Equivalent]
6(3x/2-4) =30
Side note: 3x/2 is a fraction
Answer:
x = 6
Step-by-step explanation:
Given
6( [tex]\frac{3x}{2}[/tex] - 4 ) = 30 ( divide both sides by 6 )
[tex]\frac{3x}{2}[/tex] - 4 = 5 ( add 4 to both sides )
[tex]\frac{3x}{2}[/tex] = 9 ( multiply both sides by 2 to clear the fraction )
3x = 18 ( divide both sides by 3 )
x = 6
Answer:
x = 6
Step-by-step explanation:
[tex]6( \frac{3x}{2} - 4) = 30[/tex]
Dividing both the sides by 6 ,
[tex] = > \frac{6( \frac{3x}{2} - 4) }{6} = \frac{30}{6} [/tex]
[tex] = > \frac{3x}{2} - 4 = 5[/tex]
Adding 4 on both the sides ,
[tex] = > \frac{3x}{2} - 4 + 4 = 5 + 4[/tex]
[tex] = > \frac{3x}{2} = 9[/tex]
Multiplying both the sides by 2 ,
[tex] = > \frac{3x}{2} \times 2 = 9 \times 2[/tex]
[tex] = > 3x = 18[/tex]
Dividing both the sides by 3,
[tex] = > \frac{3x}{3} = \frac{18}{3} [/tex]
[tex] = > x = 6[/tex]

What is the length of PR?
A: 13.5 inches
B: 7.5 inches
C: 10.5 inches
D: 9.5 inches
Answer:
The correct option is;
C: 10.5 inches
Step-by-step explanation:
In triangle ΔPQR the given parameters are;
The length of [tex]\overline {QP}[/tex] = 19.5 in.
The length of [tex]\overline {QR}[/tex] = 7.5 in.
In triangle ΔVWX, the given parameters are;
The length of [tex]\overline {WV}[/tex] = 13 in.
The length of [tex]\overline {WX}[/tex] = 5 in.
The length of [tex]\overline {VX}[/tex] = 7 in.
Given that we have;
[tex]\dfrac{\overline {QP}}{\overline {WV}} = \dfrac{19.5}{13} = 1.5 , \ \dfrac{\overline {QR}}{\overline {WX}} = \dfrac{7.5}{5} = 1.5[/tex]
The ratio of the corresponding sides of triangle ΔPQR and triangle ΔVWX are equal, therefore ΔPQR is similar to ΔVWX, from which we have for the corresponding sides, [tex]\overline {PR}[/tex] and [tex]\overline {VX}[/tex];
[tex]\dfrac{\overline {PR}}{\overline {WV}} = \dfrac{\overline {PR}}{\overline {7}} = 1.5[/tex]
∴ [tex]\overline {PR}[/tex] = 7 × 1.5 = 10.5
The length of [tex]\overline {PR}[/tex] = 10.5 inches
Jimmys garden has a length of 2b
+ 4 and a width of 7b + 2. What is
the perimeter of the garden?
Answer: 18b + 2
Step-by-step explanation:
Length: 2b + 4
Width: 7b + 2
I assumed the garden is a rectangle shape since the length and width are different.
Perimeter = 2( L + w)
Then we just plug the values in.
2 (2b + 4 + 7b + 2)
2 (9b + 6) = 18b + 12
So, the equation for the perimeter of Jimmy's garden will be 18b + 2.

B- (1, 3, 5, 7, 9) The domain does not repeat, therefore this is a function
C- (4, 8, 12, 16, 20) The domain does not repeat, therefore this is a function
D- (7, 7, 7, 7, 7) The entire domain repeats, therefore this cannot be a function
Correct answer is D ( 7,3 7,6 7,9 7,12 7,15)

One diet uses a ratio of 9:5:4 for carbohydrates, protein, and fat. A nutritionist is developing a diet that provides 450 calories from protein per day. Find the number of calories that should come from carbohydrates
Answer:
There are 810 calories from carbohydrates
Step-by-step explanation:
carbohydrates: protein: fat
9 :5 :4
We want 450 calories from protein
450 /5 =90
Multiply each term by 90
carbohydrates: protein: fat
9*90 :5*90 :4*90
810 450 360
There are 810 calories from carbohydrates
Answer:
810 calories are carbohydrates
Step-by-step explanation:
We know that the ratio 9:5:4 tells us that 18 equal amounts' of calories make up a meal. Now we know that 450 calories equals 5 of this parts (since protein is made out of 5 of this parts. Now we have to find out the amoung of calories in one of this 18 parts and multiply it by 9. So we do......
450 / 5 = 90
90 x 9 = 810

Step-by-step explanation:
$18 if it has 9 attendees. If there are 26 attendees, how much will the corporate team-building event cost? Solve using unit rates.
Answer:$52
Step-by-step explanation: I would first set up an equation. 9a=18 (a means attendees). Then, I would divide both sides by 9 to isolate the a. I would get a=2. So now I know that 1 attendee costs 2 dollars. If I want to find the cost for 26 attendees, all I would have to do is multiply both sides of the equation a=2 by 26. I would get 26a=52. So, 26 attendees cost $52. I hope this helps you out!

Step-by-step explanation:
(In reference to my diagram.... my diagram is similar to the diagram in the question)
We know that diagonals of a square bisect each other at right angles.
In ΔBOC ,
•OB = OC (Diagonals of square bisect each other)
=> ∠OBC = ∠OCB = (7x + 3)° (∵ OB = OC)
• ∠BOC = 90° (Diagonals intersect at right angles)
Using angle sum property of triangle ,
∠OBC + ∠OCB + ∠BOC = 90°
[tex] = > 7x + 3 + 7x + 3 + 90 = 180[/tex]
[tex] = > 14x + 6 = 180 - 90 = 90[/tex]
[tex] = > 14x = 90 - 6 = 84[/tex]
[tex] = > x = \frac{84}{14} = 6[/tex]
formula for an for the arithmetic sequence.
ah = -1, d = -7
Answer:
The formula for the arithmetic sequence will be:
[tex]a_n=-7n+6[/tex]Step-by-step explanation:
Given
a₁ = -1d = -7We know that we can get the next term of the Arithmetic sequence by taking the current term and adding the common difference.so
a₂ = a₁ + d
= -1 + (-7) ∵ a₁ = -1
= -1 - 7
= -8
similarly,
a₃ = a₂ + d
= -8 + (-7)
= -8 - 7
= -15
and so on
Thus, the Arithmetic sequence becomes
a₁, a₂, a₃, ...
-1, -8, -15, ...
as
a₁ = -1d = -7Therefore, An arithmetic sequence has a constant difference d and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = -1 and d = -7
[tex]a_n=-7\left(n-1\right)-1[/tex]
[tex]a_n=-7n+6[/tex]
Hence, the formula for the arithmetic sequence will be:
[tex]a_n=-7n+6[/tex]The triangles below are congruent and their corresponding parts are marked.

PLEASE HELP FAST I NEED A EXPERT OR HIGHER 20 POINTS! I need the domain and range of each Graph 2 number so for example 5/1 or something THANKS!!
Problem 1
Answers:
Domain: [tex]-3 \le x < 5[/tex]
Range: [tex]-4 < y \le 3[/tex]
--------------------
Explanation:
The domain is the set of allowed x inputs of a function. The smallest x value we can use is x = -3 (note the very left-most point of the graph). The right-most point involves x = 5, but we can't actually use this x value due to the open hole. So that's why we don't have "or equal to" attached to the 5.
The range is the set of possible y outputs. The lowest we can go is y = -4, but we don't include this as part of the range. The largest y can get is y = 3. So the range is [tex]-4 < y \le 3[/tex]
===========================================
Problem 2
Answers:
Domain: [tex]-2 < x < 4[/tex]
Range: [tex]-2 < y < 5[/tex]
--------------------
Explanation:
We use the same idea as in problem 1. Both endpoints are open holes, so we don't include them as part of the domain and range. For instance, we can't include x = 4 but we can get closer and closer to it. The same idea applies to the range as well.
===========================================
Problem 3
Answers:
Domain: [tex]1 \le x \le 4[/tex]
