Answer:
[tex]1.8 \text{ x } 10^5[/tex]
Step-by-step explanation:
Hello!
To multiply terms, we multiply the like terms.
Like terms:
Like terms are terms with the same degree or base. In this example, 1 and 1.8 are like terms by degree, and 10² and 10³ are like by base.
Multiply:
(1 x 10²)(1.8 x 10³)(1 x 1.8)(10² x 10³) --> exponeent rule: a^b * a^c = a^(b+c)1.8 x 10^5That's your solution! 1.8 x 10^5
What is the area of triangle rst? 6 square units 9 square units 12 square units 18 square units
The area of the considered triangle RST is given by: Option A: 9 sq. units.
How to find the area of a triangle?If we have:
Length of its base = b unitsIts height = h units long,Then we get:
Area of a triangle = [tex]\dfrac{b \times h}{2} \: \rm unit^2[/tex]
The missing image is attached below.
If we take the base of the triangle as RS, then as the line UT is perpendicular to RS (as RS is parallel to x axis and UT is parallel to y axis) and touching from the base line RS to T, thus, it can be taken as height.
Thus, we have:
Area of RST = half of length of RS (base) times length of UT (height)
As visible from image, we have:
Length of RS = 6 blocks of unit length = 6 units
Similarly, length of UT = 3 units
Thus, we get:
Area of RST = [tex]\dfrac{6 \times 3}{2} = 9 \: \rm unit^2[/tex]
Thus, the area of the considered triangle RST is given by: Option A: 9 sq. units.

8. The sum of the ages of Sarpong and Quartey is 50 years. In five years time, the age of Quartey will be four times the age of Sarpong now. How old is each boy?
Answer:
Sarpong is 11.
Quartey is 39.
Step-by-step explanation:
Let Sarpong's age now = s.
Let Quartey's age now = q.
Now:
q + s = 50
In five years, their ages will be
Sarpong: s + 5
Quartey: q + 5
q + 5 = 4s
We have a system of two equations in two variables.
q + s = 50
q + 5 = 4s
We will use the substitution method.
Solve the second equation for q.
q = 4s - 5
Substitute 4s - 5 for q in the first original equation and solve for s.
4s - 5 + s = 50
5s = 55
s = 11
q + s = 50
q + 11 = 50
q = 39
Answer:
Sarpong is 11.
Quartey is 39.

Step-by-step explanation:
Janelle says that lines l and m are skew lines.
Planes B and A intersect. Plane B is vertical and contains vertical line n. Plane A is horizontal and contains horizontal line m. Line m and n are perpendicular. Line l is on plane A and it is slightly diagonal.
Is Janelle correct?
Yes, because the lines are not parallel.
Yes, because the lines will intersect.
No, because the lines are in the same plane.
No, because the lines are perpendicular.
Answer:
C: No, beacause the lines are in the same plane.
Step-by-step explanation:
because skewed lines must lie in different planes.
just trust moi <3
The lines are in the same plane option third "No, because the lines are in the same plane" is correct.
What is a perpendicular line?Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have two lines shown in the picture, line l, and line m.
As we know the skew lines are in different planes and do not intersect.
Thus, the lines are in the same plane option third "No, because the lines are in the same plane" is correct.

does 20, 40, 30 form a right triangle
Answer: No
Step-by-step explanation: In order for a triangle to be right, the first number and second number has to be smaller than the middle number.
20+30= 50
50>40
therefore 20,40,30 can not be a right triangle
Call the 3 sides a,b,c respectively. (a=20; b=30; c=40)
To form a right triangle with 3 lengths, they must satisfied the equation : [tex]a^{2} +b^{2} =c^{2}[/tex] (aka pythagorean theorem)
Replace numbers : [tex]20^{2} +30^{2} =40^{2}\\ 400 + 900 = 1600 (false)[/tex]
-> These lengths do not form a right triangle.
What’s the greatest mad
Answer: Jason's team.
Step-by-step explanation: When finding the MAD, you need to find the mean of the data, which they said is 10. The next step is to subtract numbers from the data from the mean, which is 10 for all three dot plots. For example, for Jason's team, we need to subtract all the 7's, 8's, 11's, 12's, and 13's, because those are the only parts of the plot with data. Let's try subtracting 7 - 10. The answer is -3, but we need to make it positive, because that's how data works, so it's actually 3. You keep doing this for all three plots, which is provided below:
Jason's Team: 3, 3, 2, 2, 2, 1, 2, 3, 3, 3.
Hannah's Team: 3, 2, 2, 1, 0, 0, 1, 1, 3, 3.
Dion's Team: 1, 1, 1, 1, 0, 0, 0, 0, 1, 3.
Now, the next step is adding all these values and dividing it by ten, since that's how many numbers there are for the data.
Jason's Team MAD: 2.4.
Hannah's Team MAD: 1.6.
Dion's Team MAD: 0.8
As you can see, Jason's Team has the greatest MAD, which is your answer.

Ariana started a savings account with $240. She deposits $30 into her account at the end of each month. She wants to know how many months it will take for her account to have a balance greater than $500.
Answer:
9 months
Step-by-step explanation:
$500 - $240 = $260
$260/$30 = 8.67(3s.f.) ≈ 9 months
Recheck:
Balance after 9 months = 240 + (30×9) = 240 + 270 = $510
∴ $510 > $500

If sin(0)=24/26 what are the other two trigonomic ratios
Answer:
[tex]\begin{aligned}{&\cos \theta=\frac{10}{26} \\\bf{&\tan \theta=\frac{24}{10}}\end{aligned}[/tex]
Step-by-step explanation:
Since the angle is in the first quadrant, the values of all trigonometric functions are positive. Also. the formulas for the trigonometric functions we need to find from the problem are shown below:
[tex]\begin{aligned}\cos \theta &=\frac{x}{r} \\\tan \theta &=\frac{y}{x}\end{aligned}[/tex]
Based on the formulas listed, the value of y and r are y = 24 and r = 26 respectively. This means that in order to determine the value of the other functions, we need In compute for the value of x using the Pythagorean Theorem:
[tex]\begin{aligned}r^{2} &=x^{2}+y^{2} \\r^{2}-y^{2} &=x^{2}+y^{2}-y^{2} \quad\left[\text { \text{Subtracting \ both \ sides \ of \ the \ equation\ by} } y^{2}\right] \\r^{2}-y^{2} &=x^{2} \\\sqrt{r^{2}-y^{2}} &=\sqrt{x^{2}} \\\sqrt{r^{2}-y^{2}} &=x \\\sqrt{26^{2}-24^{2}} &=x \\10 &=x\end{aligned}[/tex]Then, substituting this to the formula to determine the answers yields:
[tex]\begin{aligned}\cos \theta &=\frac{x}{r} \\&=\frac{10}{26} \\\tan \theta &=\frac{y}{x} \\&=\frac{24}{10}\end{aligned}[/tex]
Therefore, the answers are:
[tex]\begin{aligned}&\cos \theta=\frac{10}{26} \\&\tan \theta=\frac{24}{10}\end{aligned}[/tex]
Answer:
See below
Step-by-step explanation:
We are here given that ,
[tex]\longrightarrow \sin\theta =\dfrac{24}{26}[/tex]
And we would like to find out other trigonometric ratios ( since it is not mentioned about which two I will find out all 6 ) . As we know that ,
[tex]\longrightarrow \sin\theta =\dfrac{perpendicular}{hypotenuse} =\dfrac{p}{h}[/tex]
So that ,
[tex]\longrightarrow \dfrac{p}{h} =\dfrac{24}{26}[/tex]
Let us assume the given ratio to be 24x : 26x .
So we can say that ,
hypotenuse = 26xperpendicular = 24xNow let's find out the value of base , so that we can find out the other ratios .
By Pythagoras Theorem ,
[tex]\longrightarrow (perpendicular) ^2+(base)^2=(hypotenuse) ^2[/tex]
Substitute the respective values ,
[tex]\longrightarrow (26x)^2=(24x)^2+b^2\\[/tex]
[tex]\longrightarrow 676x^2 = 576x^2+b^2\\ [/tex]
[tex]\longrightarrow b^2=100x^2\\[/tex]
[tex]\longrightarrow b =\sqrt{100x^2}\\[/tex]
[tex]\longrightarrow \boldsymbol{ b = 10x } [/tex]
Now we may find the other ratios as ,
[tex]\longrightarrow \cos\theta = \dfrac{base}{hypotenuse}=\dfrac{10x}{26x}=\boxed{\boldsymbol{\dfrac{5}{13}}}\\[/tex]
[tex]\longrightarrow \tan\theta =\dfrac{perpendicular}{base}=\dfrac{24x}{10x}=\boxed{\boldsymbol{\dfrac{12}{5}}}\\[/tex]
[tex]\longrightarrow \cosec\theta =\dfrac{hypotenuse}{perpendicular}=\dfrac{26x}{24x}=\boxed{\boldsymbol{\dfrac{13}{12}}}\\ [/tex]
[tex]\longrightarrow \sec\theta =\dfrac{hypotenuse}{base}=\dfrac{26x}{10x}=\boxed{\boldsymbol{\dfrac{13}{5}}} \\[/tex]
[tex]\longrightarrow \cot\theta =\dfrac{base}{perpendicular}=\dfrac{10x}{24x}=\boxed{\boldsymbol{\dfrac{5}{12}}} [/tex]
