Given:
Base of the triangle = 24
Height of the triangle = 10
Another side of the triangle = 26
To find:
The area of the expression of the area of the triangle.
Solution:
We know that, the area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Putting base = 24 and height = 10, we get
[tex]Area=\dfrac{1}{2}\times 24\times 10[/tex]
It can be written as
[tex]Area=\dfrac{1}{2}\times 10\times 24[/tex]
Therefore, the correct option is A.
Answer:
The correct answer is A.
One-half times 10 times 24

7h=63 so a because she charges $7 per hour and earned a total of $63
Solve for x.
Lolllllllll
Answer:
x = 15
Step-by-step explanation:
Create and solve an equation of ratios. We can do this because the smaller triangle and the larger one are similar.
x 5 + x
------- = -----------
9 9 + 3
Cross-multiplying, we get 12x = 45 + 9x,
which simplifies to 3x = 45
Solving for x, we get x = 15
Simplify by distributing

help? please and thank you
Answer:
first one
relationship between base and perpendicular is
given by tan angle
tan x=P/h
remember perpendicular is opposite side of taken angle
tan x=13/8
<x=tàn-¹(13/8)=58.39°
for second one
relationship between base and hypotenuse is given by cos angle
cos G=b/h
cos G=24/32
<G=cos-¹(24/32)=41.4 is your answer

Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
we can find angle C b/c the angles of a triangle always add to 180 , soo
180= C + 81 +63.5
35.5 = C
now that we have angle C and we know the Hyp we can use sin to find side g
where g = Opp and Hpy = 13.8 for this question
Sin(35.5) = Opp / 13.8
13.8*Sin(35.5) = Opp
8.0137 = Opp
g = 8.0137
next they ask for the area of the biggest triangle ABC ( there are two smaller ones when you use D )
we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.
we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj
Cos(35.5) = Adj / 13.8
13.8*Cos(35.5) = Adj
11.234794 =Adj
now solve for DB using cos again but with the other smaller triangle where Adj = DB now
Cos(63.5) = Adj / 8.9
8.9*Cos(63.5) = Adj
3.971160
add these two Adjs together to get the total 'a' side
15.205954
now plug in side a as the base and g as the height of our biggest triangle
Area = 1/2 * 15.205954 * 8.0137
Area = 60.9159
rounded to 2 sig figs
Area = 60.92 :) hope you get an "A" :P
What are the missing numbers?
Answer:
You can use the formula 500 * 1.03^x to solve for any year.
year 4 is 500 * 1.03^(4) = 562.75
year 6 is 500 * 1.03^(6) = 597.03
Year 7 is 500 * 1.03^(7) = 614.94
Step-by-step explanation:
The amount is increasing, and there are two main ways for that to happen. Addition and multiplication. So let's see if it keeps getting the same amount added or multiplied.
0 to 1 goes from 500 to 515, so 15 is added. but 15.45 is added from 1 to 2, so we can't just do simple addition.
using multiplication 0 to 1 has 1.03 multiplied. if you multiply by it again you do get 530.45, so we have established what is happening.
You can use the formula 500 * 1.03^x to solve for any year.
so year 4 is 500 * 1.03^(4) = 562.75
year 6 is 500 * 1.03^(6) = 597.03
Year 7 is 500 * 1.03^(7) = 614.94
Darius found that 16 out of 25 students in his class do not have a cell phone. What percent of students in his class do not have a cell phone?
Answer:
64%
Step-by-step explanation:
16/25=0.64
Answer: 64% of students do not own a cell phone
Step-by-step explanation:
First, take 100 and divide it by 25, since percentages are out of 100
100/25=4
Now multiply 4 by 16
4x16
You will get
64%

Which expression is not equivalent
to (x + 4)(x – 3)?
Answer:
A) x² + 7x - 12 is NOT equivalent to the expression.
Step-by-step explanation:
1) expand by distributing terms.
[tex] {x }^{2} - 3x + 4(x - 3)[/tex]
2) Expand by distributing terms.
[tex] {x}^{2} - 3x + 4x - 12[/tex]
3) Collect like terms.
[tex] {x}^{2} + ( - 3x + 4x) - 12[/tex]
4) Simplify.
[tex] {x}^{2} + x - 12[/tex]
The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.

Find two integers whose sum is -5 and product is -14
Answer:
-7 and 2
Step-by-step explanation:
I hope this helps :)
Let me know if you need a full explanation
Answer:
Step-by-step explanation:
a+b=-5
a=-5-b, we are also given
ab=-14, using a found above makes this become
(-5-b)b=-14
-5b-b^2=-14
b^2+5b-14=0
(b+7)(b-2)=0
So the numbers are -7 and 2.

6. Meena’s family had a pizza for dinner. The pizza was cut into 8 equal pieces. Meena ate 1 piece, her brother ate 2 pieces, and her mother ate 3 pieces. a) What fraction of the pizza did Meena eat? Her brother eat? Her mother eat? b) Which person’s fraction can you write in more than one way? Explain. c) What fraction of the pizza was eaten? What fraction was left?
Answer: Meena ate 1/8. Her brother ate 2/8, and her mom ate 3/8ths of the pizza. Her brother can be simplified from 2/8 to 1/4. Lastly, 6/8ths of the pizza has been eaten. 2/8ths is all that remains.

The area of a trapezoid is 60 square inches. One of the bases is 8 inches long. The height is 6 inches long. What is the length of the second base?
Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
[tex]\frac{1}{2}[/tex] × 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches

Answer:
Option (2)
Step-by-step explanation:
By unitary method,
∵ 8 fluid ounces contains liquid = 237 ml
∴ 1 fluid ounce liquid = [tex]\frac{237}{8}[/tex] ml
∴ 15 fluid ounces liquid = [tex]\frac{237\times 15}{8}[/tex] ml
= 444.375 ml
Therefore, total liquid in 15 fluid ounces 444 ml.
Option (2) will be the answer.

Answer:
43x+39
Step-by-step explanation:
(5)(9x)+(5)(6)+−2x+9
=45x+30+−2x+9
=45x+30+−2x+9
=(45x+−2x)+(30+9)
=43x+39
(if this helps please give brainliest and 5 stars thanks)
Answer:
43x + 39
Step-by-step explanation:
5 ( 9x + 6 ) - 2x + 9
Firstly, open up the brackets.
= 45x + 30 - 2x + 9
Now bring the like term together and simplify.
=45x - 2x + 30 + 9
= 43x + 39
