Answer:
He would factor out 4(x+5)
Step-by-step explanation:
You can't do much until the 4(x+5) is factored out.
Once it is then it'd be 3x-8=4x+20
Then you subtract 3x on both sides and subtract 20 on both sides.
You'd be left with -28=x

Answer:
X=10
sin45=10/y
0.707106781186×y=10
y=14.14213562373
2)the left angle=180-(90+60)
=180-150
=30
sin30=X/32
0.5×32=X
X=16
sin60=y/32

1. In a recent wind storm a large tree broke and made a 58° angle
between the two parts of the trunk. Which length below
is closest to the total length of the tree before the storm?
58°
14 ft
*see attachement for diagram
Answer:
40.4 ft
Step-by-step explanation:
Let the part that broke away be represented as "x"
Thus, the digram makes a right triangle shape.
The closest total length of tree before the storm = x + 14 ft
Apply trigonometric function to find x.
Reference angle = 58°
Side adjacent to reference angle = 14 ft
Hypotenuse = x
Apply CAH, which is:
Cos 58 = adj/hyp
Cos 58 = 14/x
x * Cos 58 = 14
x = 14/Cos 58
x = 26.4191188 ≈ 26.4 ft
✔️closest total length of tree before the storm = x + 14 ft = 26.4 + 14 = 40.4 ft
Solve for X

Tim is 5 pounds heavier than Amy. Let Amy's weight will be x pounds
A) Express Tim's weight in terms of x
b) if Tim's weight is 126 pounds, what is Amy's weight?
(show you work)
Answer:
A) x+5
B) 121
Step-by-step explanation:
A) If Tim is 5 pounds heavier than Amy, an equation for this situation can be modeled by x+5, where Amy is x pounds.
B) If Tim is 126 pounds, then Amy's weight is 126-5=121 pounds.
Andrew bought a math book to study for $30. Later that book was marked down 37.5 and a sales tax rate of 7 percent was included. What is the markdown amount and the sales tax amount?
Answer:
$11.25$1.31Step-by-step explanation:
Initial price = $30Mark down = 37.5%Sales tax = 7%The markdown amount is:
$30*37.5/100 = $11.25The markdown price is:
$30 - $11.25 = $18.75The sales tax amount is:
$18.75*7/100 = $1.31 (rounded to the nearest cent)Answer:
Marked down amount = $11.25
Sales tax amount = $1.31
Explanation:
The initial amount Andrew bought the book was $30.
If the book was later marked down by 37.5%, therefore the marked down will be;
[tex] \frac{37.5}{100} \times 30 = 0.375 \times 30 = 11.25[/tex]
The marked down price will be;
[tex]30 - 11.25 = 18.75[/tex]
If the sales tax rate was 7%, the sales tax amount will be;
[tex] \frac{7}{100} \times 18.75 = 1.31[/tex]

Help me please find x for this triangle!!!!
Answer:
x=30
Step-by-step explanation:
Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.

if x varies directly as y, and y=6 when x=27, find x when y=2
Answer:
x = 9
Step-by-step explanation:
Given y varies directly as y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition y = 6 when x = 27
27 = 6k ( divide both sides by 6 )
4.5 = k
x = 4.5y ← equation of variation
When y = 2 , then
x = 4.5 × 2 = 9

A company rents out 15 food booths and 23 game booths at the county fair. The fee for a food booth is $125 plus $7 per day. The fee for a game booth is $65 plus $5 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
3,370 + 220d
Step-by-step explanation:
Food booth = 15
Game booth = 23
The fair lasts for d days
Cost of a food booth = 125 + 7d
Total cost of food booth = 15(125 + 7d)
= 1875 + 105d
Cost of a game booth = 65 + 5d
Total cost of game booth = 23(65 + 5d)
= 1495 + 115d
Total amount paid to the company = Total cost of food booth + Total cost of game booth
= (1875 + 105d) + (1495 + 115d)
= 1875 + 105d + 1495 + 115d
= 3,370 + 220d
At a taffy pull, George stretched the taffy to 3 feet. Jose stretched it 1_ 1 3 times as far as George. Maria stretched it _ 2 3 as far as George. Sally stretched it _ 6 6 as far. Who stretched it the farthest? The least?
Answer:
Jose stretched the taffy the farthest and Maria stretched it the least
Step-by-step explanation:
Distance stretched by George = 3 feet
Distance stretched by Jose is [tex]1\dfrac{1}{3}[/tex] times as much as George so
[tex]3\times 1\dfrac{1}{3}=3\times\dfrac{4}{3}=4\ \text{feet}[/tex]
Distance stretched by Jose is [tex]4\ \text{feet}[/tex]
Maria streched the taffy [tex]\dfrac{2}{3}[/tex] times as George
[tex]3\times \dfrac{2}{3}=2\ \text{feet}[/tex]
Maria stretched the taffy by [tex]2\ \text{feet}[/tex]
Sally stretched it [tex]\dfrac{6}{6}[/tex] so [tex]1\ \text{feet}[/tex]
So, Jose stretched the taffy the farthest and Maria stretched it the least.
Miguel has a garden that has an area of 300 square feet. If the corn in his garden covers 160 square feet, what percent of the garden is corn?
Im not sure of my answer but I got 5.33 and the 3 repeats
Answer:
Im sorry if I'm wrong but I think it's 300+160=460
Answer:
yes your correct but wrong
Step-by-step explanation:
To find the area that's covered in corn you need to first write your fraction.
160/300
After you do that you have to turn it into a decimal.
.53333...
After that you need to turn it into a percent so your final answer will be....
53.333...%

5² = 5 * 5 = 25
. Andre drinks 15 ounces of water, which is 3 5 of a bottle. How much does the bottle hold? Use x for the number of ounces of water the bottle hold
Answer:
25
Step-by-step explanation:
Andrea drinks 15 ounces of ater
It is 3/5 of the bottle
Therefore the amount which the bottle will hold can be calculated as follows
= 15 ÷ 3/5
= 15 × 5/3
= 75/3
= 25
Hence the bottle will hold 25 ounces of water

Write the equation for each table
Answer:
Step-by-step explanation:
First table:(left)
(1, 15) (2, 30)
(30 - 15)/(2 - 1) = 15/1 = 15
y - 15 = 15(x - 1)
y - 15 = 15x - 15
y = 15x
Second table:(right)
(0, 10) (1, 25)
(25 - 10)/(1 - 0)= 15/1= 15
y - 10 = 15(x - 0)
y - 10 = 15x - 0
y = 15x + 10
Show that the two triangles given beside are similar and calculate the lengths of sides PQ and PR.
9514 1404 393
Answer:
ΔABC ~ ΔPQRPQ = 8PR = 14Step-by-step explanation:
Angles A and P are marked congruent; angles B and Q are marked congruent, so the triangles are similar by the AA similarity postulate. The similarity statement can be written ...
ΔABC ~ ΔPQR by AA similarity
__
The ratio of sides of PQR to ABC is the ratio QR/BC = 12/6 = 2. That is, each side in the larger triangle is 2 times the length of the corresponding smaller side.
PQ = 2·AB = 2·4 = 8
PR = 2·AC = 2·7 = 14
The side lengths of interest are ...
PQ = 8, PR = 14
