Answer:
56.3
6.6
Step-by-step explanation:
Answer:
A boat traveled 19 kilometers east and 53 kilometers south, how far from its starting position is it?: √3170≈56.3 km.
A 25-foot ladder rest against a house at a point 24.1 feet above the ground. How far away from the house is the base of the ladder?: √44.19≈6.65 ft.
Step-by-step explanation:
For these questions, we will need to use the pythagorean theorem: a²+b²=c², where a and b are the legs of the right triangle and c is the hypotenuse.
A boat traveled 19 kilometers east and 53 kilometers south, how far from its starting position is it?
In this question, we are looking for the hypotenuse.
19 and 53 are the legs of the triangle, so we can plug it into the equation:
19²+53²=c²
361+2809=c²
3170=c²
√3170=c
56.30275304103699, or approximately 56.3 km.
A 25-foot ladder rest against a house at a point 24.1 feet above the ground. How far away from the house is the base of the ladder?
25 is the hypotenuse since it is leaning sideways and is the longest side. 24.1 is one of the legs.
In this question, we are looking for one of the legs.
Let's plug it in: 24.1²+b²=25²
580.81+b²=625
Subtract 580.81 from both sides.
b²=44.19
b=√44.19
6.647555941848102, or approx. 6.65 ft.

Answer:
-6x⁶ + 4x⁴ - 3x³ + 4x² + 12
Step-by-step explanation:
To write an equation in standard form, you want to arrange the terms from increasing to decreasing powers/exponents.
given: 4x² - 6x⁶ + 2x³ + 12 - 5x³+ 4x⁴
First, lets arrange like terms together. Put the terms with the same exponent together.
2x³ - 5x³ + 4x² - 6x⁶ + 12 + 4x⁴
Now combine the terms with the same exponent by subtracting 5x³ from 2x³.
-3x³ + 4x² - 6x⁶ + 12 + 4x⁴
Now let's arrange the terms from increasing to decreasing powers/exponents.
-6x⁶ + 4x⁴ - 3x³ + 4x² + 12
This is your equation in standard form.
Hope this helps!
A grocery store is offering a sale on bread and soup. Kacey buys four cans of soup and three loaves of bread for $12.35. Fernando buys eight cans of soup and one loaf of bread for $13.05. a. Write equations for both Kacey's and Fernando's purchases.
Answer:
[tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]
Step-by-step explanation:
Given data
let bread be x
and soup be y
Kacey buys four cans of soup and three loaves of bread for $12.35
4x+3y=12.35-------------1
Fernando buys eight cans of soup and one loaf of bread for $13.05
x+8y= 13..05-------------2
Hence the equation for both of their purchase is [tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]

which similarity theorem can be used to prove the two triangles below similar ?
A: sss similarity theorem
B. aa similarity theorem
C. sas similarity theorem
D. not similar
The similarity theorem that proves the two given triangles are similar is: B. AA similarity theorem.
Recall:
The angle-angle similarity theorem (AA) states that if two angles in one triangle are of the same measure with two corresponding angles in another triangle, both triangles are similar to each other.
In the image given:
[tex]\angle F[/tex] in [tex]\triangle ETF[/tex] is congruent to [tex]\angle U[/tex] in [tex]\triangle VTU[/tex] ([tex]\angle F = \angle U = 78[/tex])
[tex]\angle ETF = \angle VTU[/tex] (vertical angles are equal)
This implies that two angles in [tex]\triangle ETF[/tex] are congruent to two corresponding angles in [tex]\triangle VTU[/tex].
Therefore, both triangles can be proven to be similar by the angle-angle similarity theorem (AA).

Answer:
Choice #1) 4.7 cm
Step-by-step explanation:
circumference of full circle = 2(r)(3.14)
a full circle would be = 2(3)(3.14) = 18.84 cm
It is 1/4 circle so 18.84/4=4.7 cm
Answer:
10.7
Step-by-step explanation:
1. I first grabbed a ruler to measure the other straight side of the figure.
2. Both of the straight sides were 3 cm so I knew that the answer had to be greater than 6 cm.
3. I then estimated that the other side was longer than the 3 cm.
4. I then had to my logic to figure out the answer and I very quickly realized that 4.7 cm would not make since because that is less than 6 cm. I know 7.7 cm would not make since because I knew the curved side was longer than 3 cm not shorter. 18.8 cm did not make since because that answer has WAY to much cm. Using the process of elimination, 10.7 cm was the only answer that made since.

Answer:
Step-by-step explanation:
center (-1, -2) , trough point ( 6, 4)
equation of the circle
r² = (x-h)²+(y-k)², where (h, k) are the coordinate of a circle so h=-1, k=-2
r² =(x+1)²+(y+2)², but (x, y ) are coordinates for any point on the circle so x=6 and y= 4
r² =(6+1)²+(4+2)²
r²= 7² +6²
r²= 85
so the equation is
(x+1)²+(y+2)²= 85
to find the points on the circle substitute in the equation x and y
(-10+1)²+(0+2)²= 85 ; 85=85 true
so the pint on the circle is (-10, 0)

Jim is making salsa. His recipe calls for 3 1 3 cups of tomato sauce for every 1 6 cups of cilantro. If Jim has 1 cup of cilantro, how many cups of tomato sauce will he need?
Answer: 20 cups of tomato
Step-by-step explanation:
From the question, we are informed that Jim is making salsa and that his recipe calls for 3 1/3 cups of tomato sauce for every 1/6 cups of cilantro.
If Jim has 1 cup of cilantro, thus simply means that he has multiplied the previous cup of cilantro by:
= 1 ÷ 1/6
= 1 × 6/1
= 6
Therefore, we would also multiply the cups of tomato by 6. This will be:
= 3 1/3 × 6
= 10/3 × 6
= 20 cups of tomato

Chipotle Burritos are normal distributed with a mean length of 200mm and a standard deviation of 8mm. What is the probability that a burito picked at random is shorter than 190mm?
Answer: 0.1056
Step-by-step explanation:
Given: Chipotle Burritos are normal distributed with
Mean = 200 mm
Standard deviation = 8 mm
Let x be the length of a random burrito.
The probability that a burrito picked at random is shorter than 190mm will be :
[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]
Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

Kate went to the store and bought some pants for $22 and 4 shirts. She spent a total of $52. How much did each shirt cost? Write an equation to represent this situation.
Answer:
$7.5
$22 + 4x = 52
Step-by-step explanation:
Given that:
Cost of pants = $22
Number of shirts = 4
Total spent = $52
Let the cost per shirt = x
Cost of pants + cost of shirts = total
$22 + 4x = 52
4x = 52 - 22
4x = 30
x = 30 / 4
x = 7.5
Cost per shirt = $7.5

Triangle ABC has Vertices A(1, 2), B(3, 5), and C(4, 3). Using the origin as the center of dilation, Triangle ABC is dilated by a scale factor of 3 to create Triangle A ′ B ′ C ′ . Which statement can be used to justify that Triangle ABC is similar to Triangle A ′ B ′ C ′ ?
Answer:
AA ≅ AA postulate
Step-by-step explanation:
Given
[tex]A=(1,2)[/tex]
[tex]B = (3,5)[/tex]
[tex]C = (4,3)[/tex]
[tex]k = 3[/tex] --- scale factor
Required
Determine which statement that justifies the similarities between ABC and A'B'C'
When ABC is dilated by a scale factor of 3 to form A'B'C', the sides A'B'C are 3 times as large as the sides of ABC.
However, all three angles of both triangles remain the same. This is so, because dilation do not affect angles.
So, a statement that can be used to justify the similarities is: AA ≅ AA
