Step-by-step explanation:
[tex]\sf Cos\ \theta = \frac{Adjacent}{Hypotenuse}[/tex]
Where [tex]\theta[/tex] = 34° , Adjacent = x and Hypotenuse = 4.8
[tex]\sf Cos \ 34 = \frac{x}{4.8} \\0.829 = \frac{x}{4.8} \\x = 0.829*4.8\\x = 4.0[/tex]

[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
The triangle is a right triangle.
We can use trig functions to solve for the problem.
[tex]\sf \displaystyle cos (\theta) = \frac{adjacent}{hypotenuse }[/tex]
[tex]\sf \displaystyle cos (34) = \frac{x}{4.8 }[/tex]
Multiplying both sides by 4.8.
[tex]\sf \displaystyle 4.8 \cdot cos (34) = \frac{x}{4.8 } \cdot 4.8[/tex]
[tex]\sf x = 3.97938034[/tex]
The value of x is approximately 4.

The vet told Jake that his dog, Kevin, who weighed 78 pounds, needed to lose 14 pounds. Jake started walking Kevin every day and changed the amount of food he was feeding him. Kevin lost 1.5 pounds in the first week. Jake wants to follow the vet's advice. So, how many weeks, w, will it take Kevin to lose the weight in pounds, p.
Answer:
It will take approximately 9.3 weeks for Kevin to lose the
Step-by-step explanation:
current weight of Dog = 78 pounds
Required weight to be shed off = 14 pounds
weight lost in 1 week = 1.5 pounds
Let the number of weeks required to lose 14 pounds be w.
Assuming that the rate of weight loss per week is constant
(weight lost in 1 week) × (number of weeks) = 14 pounds
1.5 × w = 14
w = 14 ÷ 1.5 = 9.3 weeks
Therefore it will take approximately 9.3 weeks for Kevin to lose the weight

\bigg(\frac{3+1}{3}\bigg) m\angle ABE = 90\degree \\
\frac{4}{3} m\angle ABE = 90\degree \\
m\angle ABE = 90\degree \times \frac{3}{4}\\
m\angle ABE = \frac{270\degree}{4}\\

Answer:
y = -7, y = -3
Step-by-step explanation:
(y - 3)² = 2y² + 4y + 30
expand:
y² - 6y + 9 = 2y² + 4y + 30
subtract 30 from both sides
y² - 6y + 9 - 30= 2y² + 4y + 30 - 30
simplify:
y² - 6y - 21 = 2y² + 4y
subtract 4y from both sides
y² - 6y - 21 -4y = 2y² + 4y - 4y
simplify:
y² - 10y - 21 = 2y²
subtract 2y² from both sides
y² - 10y - 21 - 2y² = 2y² - 2y²
simplify:
-y² - 10y - 21 = 0

Answer:
the answer is the last choice
Step-by-step explanation:
Last year Kerry's take home pay was $15 000. She spent of her take
home pay on rent. She used the rest of her take home pay for living
expenses, clothes and entertainment in the ratio 3:1:2 How much did
Kerry spend on entertainment last year?
Answer:
3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
If a line with slope = 2 passes through the points (4,-8) and (x,2), find x
Answer:
x = 9
Step-by-step explanation:
Calculate the slope m using the slope formula then equate to 2
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 8) and (x₂, y₂ ) = (x, 2 )
m = [tex]\frac{2+8}{x-4}[/tex] = [tex]\frac{10}{x-4}[/tex] = 2 ( multiply both sides by x - 4 )
2(x - 4) = 10 ( divide both sides by 2 )
x - 4 = 5 ( add 4 to both sides )
x = 9
12. The sum of four consecutive numbers in A.P. is 32 and the ratio of the product of the first and last terms to the product of two middle terms is 7:15. Find the number.
Answer:
2, 6, 10, 14
or
14, 10, 6, 2.
Step-by-step explanation:
Let the four consecutive numbers in A.P. be a - 3d, a - d, a + d, a + 3d
According to the first condition:
a - 3d + a - d + a + d + a + 3d =32
4a = 32
a = 32/4
a = 8
According to the second condition:
[tex] \frac{(a - 3d)(a + 3d)}{(a - d)(a + d)} = \frac{7}{15} \\ \\ \frac{ {a}^{2} - (3d)^{2} }{ {a}^{2} - {d}^{2} } = \frac{7}{15} \\ \\ \frac{ {a}^{2} - 9d^{2} }{ {a}^{2} - {d}^{2} } = \frac{7}{15} \\ \\ \frac{ {8}^{2} - 9d^{2} }{ {8}^{2} - {d}^{2} } = \frac{7}{15} \\ \\ \frac{ 64 - 9d^{2} }{ 64 - {d}^{2} } = \frac{7}{15} \\ \\ 15(64 - 9 {d}^{2} ) = 7(64 - {d}^{2} ) \\ \\ 960 - 135 {d}^{2} = 448 - 7 {d}^{2} \\ \\ 960 - 448 = 135 {d}^{2} - 7 {d}^{2} \\ \\ 512 = 128 {d}^{2} \\ \\ {d}^{2} = \frac{512}{128} \\ \\ {d}^{2} = 4 \\ \\ d = \pm 2 \\ \\ when \: d = 2 \\ a - 3d = 8 - 3 \times 2 = 8 - 6 = 2 \\ a - d = 8 - 2 = 6 \\ a + d = 8 + 2 = 10 \\ a + 3d = 8 + 3 \times 2 = 8 + 6 = 14 \\\\ when \: d = - 2 \\ a - 3d = 8 - 3 \times ( -2 ) = 8 + 6 = 14 \\ a - d = 8 -( - 2 )= 8 + 2 = 10 \\ a + d = 8 + ( - 2 )= 8 - 2 = 6\\ a + 3d = 8 + 3 \times ( - 2 )= 8 - 6 = 2 \\[/tex]
Thus the four consecutive numbers of the A. P. are 2, 6, 10, 14 or 14, 10, 6, 2.

What is the image of the point (0,5) after a rotation of 180° counterclockwise about
the origin?
Answer:
(0, -5)
Step-by-step explanation:
When we rotate a point around the origin 180°, the original coordinates (x, y) become (-x, -y).
So,
-0 is just 0 (since 0 is both negative and positive)
-(5) is -5
This makes our new point (0, -5).

Please give brainliest
Answer:
Rectangle
Step-by-step explanation:
Opposite sides (1, 1), (4,1) and (1, 3), (4,3) are horizontal and have length 3.
Opposite sides (1, 1), (1, 3) and (4, 1), (4,3) are vertical and have length 2.
There two pairs of opposite sides that are congruent, so this is a parallelogram. Since not all sides are congruent, this is not a square or a rhombus.
In addition, vertical sides and horizontal sides form right angles, so this is a parallelogram with right angles. It is a rectangle.

3) Marvin bought a t shirt that was on sale for 20% off. He paid $14.21. for the t-shirt including
sales tax of 11 percent. Use this information to answer questions a and b.
a Circle the equation that can be used to find the original price of the t-shirt.
(c - 20c) +.11(e - 200) – 14.21
. 11(x - 20c) = 14.21
11(22.81 - 20(14.21)) = C
116.80c) + (c - 20c) = 14.21
b. Solve the equation and interpret the solution
Answer:
(a) 14.21 = 0.80x + 0.11 (0.80x)
(b) The original price of the t-shirt was $16.
Step-by-step explanation:
The information provided are:
Marvin bought a t shirt that was on sale for 20% off.He paid $14.21. for the t-shirt.The sales tax percent was 11%.(a)
Assume that the original price of the t-shirt was $x.
The discounted amount would be, x ( 1 - 0.20) = 0.80x.
The sales tax amount would be, 0.11 (0.80x).
Then the total amount paid by Marvin can be represented by the equation:
Total = Discounted amount + Sales tax amount
14.21 = 0.80x + 0.11 (0.80x)
Thus, the equation that can be used to find the original price of the t-shirt is:
14.21 = 0.80x + 0.11 (0.80x)
(b)
Compute the value of x as follows:
[tex]14.21 = 0.80x + 0.11 (0.80x)[/tex]
[tex]14.21=0.80\times 1.11\times x[/tex]
[tex]x=\frac{14.21}{0.80\times 1.11}\\\\x=16.0023\\\\x\approx \$16[/tex]
Thus, the original price of the t-shirt was $16.
