What is the area of the figure? O 1240 units? 0 1250 units? o 2490 units? 0 3730 units
Answer:
2490
Step-by-step explanation:
The 2 shapes are triangle and trapezoid
Area of a triangle formula: A= h×b/2
A=40×62/2
A=1240
Area of a trapezoid formula: base¹+base²/2×height
A= 38+62/2×25
A=1250
Add both areas together
1250+1240=2490

Answer:
Step-by-step explanation:
A(x) = 4x³ - 4x²- 23x + 20
B(x) = 2x² + 3x - 4
C(x) = 2x - 5
a). A(x) + B(x) + C(x) = (4x³ - 4x²- 23x + 20) + (2x² + 3x - 4) + (2x - 5)
= 4x³ + (-4x² + 2x²) + (-23x + 3x + 2x) + (20 - 4 - 5)
= 4x³- 2x²- 18x + 11
b). A(x) - 2B(x) + 2C(x) = (4x³ - 4x²- 23x + 20) - 3(2x² + 3x - 4) + 2(2x - 5)
= 4x³ - 4x² - 23x + 20 - 6x² - 9x + 12 + 4x - 10
= 4x³ - 10x²- 28x + 22
c). A(x) . B(x) = (4x³ - 4x² - 23x + 20)(2x² + 3x - 4)
= 2x²(4x³ - 4x² - 23x + 20) + 3x(4x³ - 4x² - 23x + 20) - 4(4x³ - 4x² - 23x + 20)
= 8x⁵ - 8x⁴- 46x³ + 40x² + 12x⁴- 12x³ - 69x² + 60x - 16x³+ 16x²+ 92x - 80
= 8x⁵+ 4x⁴- 74x³- 13x²+ 152x - 80
d). [B(x)]² = (2x² + 3x - 4)²
= 2x²(2x² + 3x - 4) + 3x(2x² + 3x - 4) - 4(2x² + 3x - 4)
= 4x⁴ + 6x³ - 8x² + 6x³ + 9x² - 12x - 8x² - 12x + 16
= 4x⁴ + 12x³- 7x²- 24x + 16

If sin y° = 9/c and tan y° = 9/d, what is the value of cos y°?
Answer:
d/cStep-by-step explanation:
Given:
sin y° = 9/c and tan y° = 9/dWe know that
tan α = sin α /cos α ⇒ cos α = sin α / tan αSolving for cos y°, by substituting values:
cos y° = sin y° / tan y° cos y° = 9/c ÷ 9/d = 9/c × d/9 = d/cAnswer:
the answer to your question is d/c

Park Jimin paid $125 to have his hair colored and cut. If he tips his hairdresser 15% of his bill, how much was the tip?
Money paid by Park Jimin = $125
We need to find the tip , so,
→ 15% of the amount paid
→ $ 125 (15/100)
→ $ 18.75
Hence, the tip is of $ 18.75

Step-by-step explanation:
The ratio of boys to girls in a group is 5:3. If there are 18 more boys than girls, work out how
many people there are in total.
45 boys, 27 girls
============================================================
Explanation:
g = number of girls
g+18 = number of boys, since there are 18 more boys than girls
For example, if g = 7, then g+18 = 7+18 = 25. In this example, we have 7 girls and 25 boys. The problem with this example is the ratio of boys to girls is 25:7 which is not equal to 5:3
We could use trial and error until we land on the solution, or we can use algebra as shown in the next section.
-------------------
The ratio of boys to girls is 5:3, meaning
(number of boys)/(number of girls) = 5/3
which turns into
(g+18)/g = 5/3
after we make the proper substitutions
Let's solve for g
(g+18)/g = 5/3
3(g+18) = 5g
3g+54 = 5g
54 = 5g-3g
54 = 2g
2g = 54
g = 54/2
g = 27
There are 27 girls.
This leads to,
g+18 = 27+18 = 45
So there are 45 boys
In total, we have 27+45 = 72 people
-----------------------------
Checking the answer:
The claim is that 45/27 is the same as 5/3
For now assume that claim is true. Set the fractions equal to each other and use cross multiplication like so
45/27 = 5/3
45*3 = 27*5
135 = 135
The third equation has the same thing on both sides, so it's a true equation. This must mean the first equation is true as well. Therefore, 45:27 and 5:3 are the same ratio and the answer is confirmed.
You could also use your calculator to note that
45/27 = 1.667
5/3 = 1.667
both decimal values are approximate.
The people there are in total of 72 students
Let the ratio of boys to girls be 5x: 3x
The ratio of boys to girls in a group is 5:3.
What is the formula?
no. of boys = 18 + no. of girls
=> 5x = 18 + 3x
=> 5x - 3x = 18
=> 2x = 18
=> x = 18/2
x= 9
No. of boys = 5x
No. of boys= 5 × 9
No. of boys= 45
No. of girls = 3x
No. of girls= 3 × 9
No. of girls= 27
Total = 45 + 27
Total= 72
Hence, there are 72 students there.

Put together, Dulcina and Tremaine have 129 total matchbooks. Tremaine's collection has 39 fewer matchbooks in it than Dulcina's collection. How many matchbooks are in Tremaine's collection? How many matchbooks are in Dulcina's collection?
Answer:
Let the Dulcina's collection be 'x'
Let the Tremaine collection be 'x-39'
x + x - 39 =129
2x = 129 +39
2x = 168
x = 168/2
x = 84
Dulcina's collection = x = 84
Tremaine's collection = x - 39 = 84 - 39 = 45

P(3,-5) T(x, y) = (x +4, y-3)
P' = ([?], []).
Enter the number that belongs in
the green box.
Enter
Answer:
The number that belongs in the green P' = ([?], [ ]) with P' = (7, -8) box is;
7
Step-by-step explanation:
The coordinate of the given point 'P' is P = (3, -5)
The preimage of (x, y) after the translation, [tex]T_{(x, \ y)}[/tex] = (x-coordinate + 4, y-coordinate - 3)
Therefore, the translation, [tex]T_{(x, \ y)}[/tex] = T₍₄, ₋₃₎
Therefore, we have;
Preimage P(3, -5) under the translation T₍₄, ₋₃₎ gives the image P' as follows
P(3, -5) [tex]\overset{T_{\left ( 4, \, -3 \right )}}{\rightarrow}[/tex]P'(3 + 4, -5 - 3) = P'(7, -8)
Therefore, the number that belongs in the green box is the x-coordinate value of the point P'(7, -8) which is seven.
If you poured 97 mL of water into a jar that can hold 1 l what Mark does a water come closest to on the jar
Answer:
Near the mark at the bottom reading 100 mL
Step-by-step explanation:
We know that 1000 mL = 1 L
It means that 1 liter of a liquid contains 1000 milliliter of the liquid. In other words, in 1 liter there is 1000 mL of the liquid. And milliliter means one thousandth of a liter.
So when we pour 97 mL of the water in a jar which has a capacity to fill water up to 1 L or 1000 mL, the water filling the jar will come close to the bottom of the jar which is approximately 100 mL . It will rise up to the mark which reads 100 mL in the jar that is graduated.

Which problem can be solved using the equation 9x + 14 = 100
Answer:
rounded form: x = 9.56
Step-by-step explanation:
9x + 14 =100
you would 1st subtract 14 from 100 so you're left with
9x = 86
now to get x alone, you divide both sides by 9 so now you have
x = 9.56
