Two triangles are similar. The corresponding sides have a ratio of 2:5. If the smaller triangle has a
side length of 14 centimeters, what is the measurement of the corresponding side of the larger triangle?
Answer:
35 centimeters (the person above me i believe is correct:)
Step-by-step explanation:
you divide 5/2 and that equals 2.5 then multiply 14*2.5 and that equals 35.
4. Find the sale price of $4,200 with a 35% markdown. (Change 35% to a decimal by dividing by a 100 then multiply by 4200 to get the markdown. Then subtract Markdown from 4200) For a Markup you would add.
Answer:
$27.30
Step-by-step explanation:
4200÷100=42
1% = 42
42×35=1470
4200-1470=2730

find the x-intercepts of the function g(x)=8x^{2} −10x−3
Answer: [tex][-\frac{1}{4}, \frac{3}{2}][/tex]
Step-by-step explanation:
Factor:
[tex]g(x) = 8x^{2} -10x-3[/tex][tex]g(x) = x^{2} -10x-24[/tex] ---> multiply constant (3) by coefficient of first term[tex]g(x) = (x+\frac{2}{8})(x-\frac{12}{8} )[/tex] ---> factor (multiplies to 24 and adds to -10. Divide factors by 8 since you multiplied by 8 in previous step)[tex]g(x) = (x+\frac{1}{4})(x-\frac{3}{2})[/tex] ---> simplify[tex]g(x) = (4x+1)(2x-3)[/tex] ---> move denominator of fraction to be coefficient of xSolve:
[tex]0 = (4x+1)(2x-3)[/tex] ---> set equation equal to 0.[tex]0 = 4x + 1[/tex] ---> make each parentheses equal to 0.[tex]-1 = 4x[/tex] [tex]-\frac{1}{4} = x[/tex] ---> x intercept[tex]0 = 2x - 3[/tex] [tex]3 = 2x[/tex] [tex]\frac{3}{2} = x[/tex] ----> x interceptCelina built a model of a triangular pyramid.

Answer:
The measure of the first angle is 32° and the measure of the second angle is 49°. (h = 32° & c = 49°)
Step-by-step explanation:
For the first triangle, we know that when you add up all the angles in a triangle, you'll end up with 180°. Keeping that in mind, all you have to do to find the third angle is add up the two we already know and subtract it from 180°.
1. 58° + 90° = 148° --> I know that the second angle is 90° because it's a right
180° - 148° = 32° triangle.
2. 82° + 49° = 131°
180° - 131° = 49°
Hope this helps,

There are three quarters, five dimes, and twelve pennies in a bag. When a coin is drawn from the bag, it is replaced. If two coins are drawn at random, determine each probability.
7. P(a quarter and then a penny) 8. P(a nickel and then a dime)
9. P(two pennies) 10. P(a dime and then a quarter)
Please don't just answer for points I actually need help
Answer:
9
Step-by-step explanation:
there are 4 more pennies with adding the dimes and quarters together so there is most likely a high probability for 2 pennies to be pulled.

Nelson is planning out his monthly budget and estimates that he spends $250 on food each month. When he got his bank statement, he discovered that his actual food expense for the month was $315. Calculate his percent error. Round to the nearest whole percent.
Answer:
21
Step-by-step explanation:
250 / 315 = 0.79
0.79 x 100 = 79
100 - 79 = 21
Which of the relationships below represents a function with the same rate of change as the function y=x-4?
Answer:
D
Step-by-step explanation:
The slope for the first one is 1 since x stands alone. You have to find the slope for each, and find the one that matches, so divide the change in y over change in x, or for the graphs find where the points are, find the difference in the y and x values and do change in y over change in x. For A, the slope would be -1, so it wouldn’t work. For B, the slope would be -5/4, so it wouldn’t match. For C, the slope would be -4/2, so it wouldn’t be a match. D the slope would be 1 so it is the only one that matches.
Please help!! write a detailed explanation of how you how got your answer!! Thank You!!!
Not sure if you still need the answer
But it's 120+20[tex]\pi[/tex]
Because the 3 boxes in the middle are cubes, all three are 10x10, and perimeter of a cube is each side added up.
All together it would be 40+40+40 which equals 120.
Then for the semi-circles, the perimeter formula is 1/2([tex]\pi[/tex]d) d standing for diameter. Since we can tell that the diameter takes up 2 full cubes, we know that the diameter is 20. However since it's a semi-circle we cut that in half. So 10[tex]\pi[/tex]
10[tex]\pi[/tex]+10[tex]\pi[/tex]=20[tex]\pi[/tex]
So then your final answer is 120+ 20[tex]\pi[/tex]
