Answer:
B = 10.5
Step-by-step explanation:
From the figures, it looks like triangle HER is similar to triangle KPS.
From that we get
[tex] \dfrac{HE}{KP} = \dfrac{ER}{SP} [/tex]
[tex] \dfrac{B}{7} = \dfrac{7.5}{5} [/tex]
Multiply both sides by 7.
B = 10.5
Answer:
B = 10.5
C = 10
Step-by-step explanation:
When one divides the corresponding sides of similar triangles, one will attain the ratio of similitude. If one multiplies one of the similar triangle's sides by the ratio of similitude, then one will attain the corresponding side of the similar triangle. In simple terms, the ratio of similitude is the scaling factor between two similar polygons.
As per the given information, the two triangles are similar, therefore one can set up a proportion with their corresponding sides;
[tex]\frac{ER}{PS} = \frac{HE}{KP} = \frac{HR}{KS}[/tex]
Substitute;
[tex]\frac{7.5}{5} = \frac{B}{7} = \frac{15}{C}[/tex]
Solve for B with cross products;
[tex](7.5)(7) = (5)(B)\\52.5 = 5B\\10.5=B[/tex]
Solve with cross products for C;
[tex](7.5)(C) = (15)(5)\\7.5C = 75\\C=10[/tex]
Karl set out to alaska on his truck the amount of fuel remaining in hi truck tank in liters as a function of distance driven in kilometers is graphed
What distance did Karl travel by the time he had 200 liters of fuel
Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.
Why it is and what is distance?
To determine the distance Karl traveled by the time he had 200 liters of fuel remaining in his truck, we need to examine the graph provided.
From the graph, we can see that when the fuel remaining in the truck tank is 200 liters, the corresponding distance driven is approximately 420 kilometers.
Therefore, Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.
Distance is the physical length between two points or objects. It is a scalar quantity that measures the amount of space between two locations, without regard to the direction of travel. Distance can be measured in various units such as meters, kilometers, miles, and so on.
In physics, distance is often distinguished from displacement, which is a vector quantity that measures the change in position of an object relative to its starting point.

Need answer please ❣️
Now na Brainlest ❣️ ko maka answer ❣️
Answer:
Step-by-step explanation:
In this question we will solve the polynomials by adding or subtracting the similar terms.
1). (-3x² - 8x + 2) + (-5x² - 9x - 2)
= (-3x²- 5x²) - (8x + 9x) + (2 - 2)
= (-8x²) - 17x + 0
= -8x² - 17x
2). (-2x² + 7x - 1) - (8x² - 6x + 5)
= (-2x² - 8x²) + (7x + 6x) - (1 + 5)
= -10x² + 13x - 6
3). (5x²- 5xy - 10y²) + (5x²+ 5xy + 10y²)
= (5x² + 5x²) + (-5xy + 5xy) + (-10y² + 10y²)
= 10x²
4). (2 + 8x + 4x²) - (9 + 6x + 2x²)
= (2 - 9) + (8x - 6x) + (4x² - 2x²)
= -7 + 2x + 2x²
5). (4x³ + 5x²+ 3x) - (3x³ + 6x²- 1)
= (4x³ - 3x³) + (5x² - 6x²) + 3x + 1
= x³- x² + 3x + 1

295% of what number is 177?
Answer: 522.15 I think
Step-by-step explanation:
1. We assume, that the number 177 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 177 is 100%, so we can write it down as 177=100%.
4. We know, that x is 295% of the output value, so we can write it down as x=295%.
5. Now we have two simple equations:
1) 177=100%
2) x=295%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
177/x=100%/295%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 295% of 177
177/x=100/295
(177/x)*x=(100/295)*x - we multiply both sides of the equation by x
177=0.33898305084746*x - we divide both sides of the equation by (0.33898305084746) to get x
177/0.33898305084746=x
522.15=x
x=522.15
now we have:
295% of 177=522.15
