Answer:
nice and
since it is complementary then a +b = 90
and substitution gives
69 + b = 90
b = 21
hope this helped and brainliest pls
Answer:
21
Step-by-step explanation:
I assume you are dealing with complementary angles.
m<a + m<b = 90
69 + m<b = 90
m<b = 90 - 69
m<b = 21
solve for answer lol

Step-by-step explanation:
Jules is aboard a submarine studying marine life. She’s trying to find a family of whales and must time when the submarine descends perfectly to find them. Her submarine is 22 feet below sea level and descends at a constant rate of 12 ft. per minute. The submarine must stay no less than 400 ft. below sea level. Let m = the number of minutes. Write an inequality that can be used to find how long the submarine can descend. Then, write the time the submarine can descend.
Answer:
32.33 <= m
Step-by-step explanation:
Since we are dealing with below sea level our initial starting point and max level will both be negative values, while our descending rate will also be negative because we are going down. Using the values provided we can create the following inequality...
-400 <= -12m - 12
Now we can solve the inequality to find the max number of minutes that the submarine can descend.
-400 <= -12m - 12 ... add 12 on both sides
-388 <= -12m ... divide both sides by -12
32.33 <= m
Answer:
-22 + -12 >(or equal to) -400.at most 31.5 minutes

find the tangent of each acute angle.
Answer:
Image 1
[tex]\tan A = \frac{45}{24}= \frac{15}{8}[/tex]
[tex]\tan B = \frac{24}{45} = \frac{8}{15}[/tex]
Image 2
[tex]\tan D = \frac{15}{36} = \frac{5}{12}[/tex]
[tex]\tan E = \frac{36}{15} = \frac{12}{5}[/tex]
Image 3
[tex]\tan P = \frac{32}{24} = \frac{4}{3}[/tex]
[tex]\tan Q = \frac{24}{32} = \frac{3}{4}[/tex]
Step-by-step explanation:
Trigonometrically speaking, the tangent of an angle in a right triangle is the ratio of the length opposite to the angle to the length adjacent to the angle. Then, we solve for each case:
Image 1
[tex]\tan A = \frac{45}{24}= \frac{15}{8}[/tex]
[tex]\tan B = \frac{24}{45} = \frac{8}{15}[/tex]
Image 2
[tex]\tan D = \frac{15}{36} = \frac{5}{12}[/tex]
[tex]\tan E = \frac{36}{15} = \frac{12}{5}[/tex]
Image 3
[tex]\tan P = \frac{32}{24} = \frac{4}{3}[/tex]
[tex]\tan Q = \frac{24}{32} = \frac{3}{4}[/tex]
An Ice company charges $8.16 for 6 bags of ice. If you buy 8 bags of ice how much would it cost you? help asap its due tomorrow
Answer:
Answer:$10.88
Step-by-step explanation:
First we need to see how much one bag of ice costs. To do this we need to divide 8.16 by 6.
8.16÷6=1.36
Now that we know how much a bag of ice cost we need to calculate how much 8 bags costs. This means we have to multiply 1.36 by 8.
1.36x8= 10.88.
The answer is $10.88
Which is the correct choice.

Triangle QRS was dilated using the dilation rule DP,4.
Point P is the center of dilation. Triangle Q R S is dilated to create triangle Q prime R prime S prime. The length of P R is 3.
What is PR'?
6 units
9 units
12 units
15 units
Using the dilation rule, the length of P'R' is: C. 12 units.
What is Dilation?Dilation, as a type of transformation, is the enlargement or reduction of a shape to create a new image which is similar to the original image.If the scale factor is a whole number, it means it's an enlargement, if fraction, it means it is a reduction.Given that the scale factor of dilation is 4, and PR is 3.
Therefore:
P'R' = 4(PR)
P'R' = 4(3)
P'R' = 12 units.
Therefore, using the dilation rule, the length of P'R' is: C. 12 units.

find the whole quantity if 5 percent of it is 500
Answer:
10,000
Step-by-step explanation:
500/0.05= 10,000
You take the amount you are given divided by the decimal form of the percentage you are given to find the answer. It's a reverse from the way you find 5% of 10,000.
0.05=5%
Check your work: 10,000*5%= 500

Si se compran tres chicles y un tamarindo y se paga $15 y se compran dos chicles y tres tamarindos y se paga $31 ¿que cuesta cada tamarindo?
Responder:
9
Explicación paso a paso:
Dejar :
Mascar chicle = x
Tamarindo = y
3x + y = 15 - - - (1)
2x + 3y = 31 - - - (2)
De 1)
y = 15 - 3x - - (3)
Por lo tanto,
2x + 3 (15 - 3x) = 31
2x + 45 - 9x = 31
-7x = 31 - 45
-7x = - 14
x = 2
De (3):
y = 15 - 3 (2)
y = 15 - 6
y = 9
Which of the following lengths will form a triangle?
A: 12.6 cm, 5.4 cm, 5.4 cm
B: 7.2 cm, 5.9 cm, 1.3 cm
C: 11.5 cm, 4.2 cm, 7.6 cm
D: 3.1 cm, 6.6 cm. 10.4 cm
9514 1404 393
Answer:
C: 11.5 cm, 4.2 cm, 7.6 cm
Step-by-step explanation:
In order for the lengths to form a triangle, the sum of the shortest two must exceed the longest.
A. 5.4 +5.4 = 10.8 < 12.6
B. 1.3 +5.9 = 7.2
C. 4.2 +7.6 = 11.8 > 11.5 . . . . will make a triangle
D. 3.1 +6.6 = 9.7 < 10.4
What is the surface area of the following prism?
Answer:
102cm²
Step-by-step explanation:
Surface Area = BH +Lp
B is the base area
H is the height of the Prism
L is the slant height
p is t perimeter of its base
B =1/2 ×3×4
B= 6cm²
H = 7cm
L = 5cm
P = 3cm+4cm+5cm
P = 12cm
Substitute
TSA = 6(7)+5(12)
TSA = 42+60
TSA = 102cm²
Hence the total surface area of the shape is 102cm²

-9x + 9y = 9
y = 8X + 1
Answer:
x=0
Step-by-step explanation:
−9x+9(8x+1)=9
Step 1: Simplify both sides of the equation.
−9x+9(8x+1)=9
−9x+(9)(8x)+(9)(1)=9(Distribute)
−9x+72x+9=9
(−9x+72x)+(9)=9(Combine Like Terms)
63x+9=9
63x+9=9
Step 2: Subtract 9 from both sides.
63x+9−9=9−9
63x=0
Step 3: Divide both sides by 63.
