Answer:
Total earning last week = 225
Step-by-step explanation:
Given:
Earning per hour = 12 pesos
Deduct per late delivery = 15 pesos
Total number of hour = 25 hour
Total number of late delivery = 5
Find:
Total earning last week
Computation:
Total earning last week = (Total number of hour)(Earning per hour) - (Deduct per late delivery)(Total number of late delivery)
Total earning last week = (12)(25) - (15)(5)
Total earning last week = 300 - 75
Total earning last week = 225

Solve :-
2y+1=17
......
Answer:
Solution given:
2y+1=17
subtracting both side by 1
2y+1-1=17-1
2y=16
dividing both side by 2
2y/2=16/2
y=8

Answer:
V = 8 m/s
Step-by-step explanation:
Assuming that the object was at rest, so μ = 0

Y and x have a proportional relationship, and y=4 when x=12
Answer:
multiply 4 by 12 okay bro
Answer:
y = [tex]\frac{1}{3}[/tex] x
Step-by-step explanation:
Given that y and x are proportional then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 4 when x = 12 , then
4 = 12k ( divide both sides by 12 )
k = [tex]\frac{4}{12}[/tex] = [tex]\frac{1}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x ← equation of proportion
The given figure shows a small garden. The shaded area is
reserved for planting flowers and the rest of the area is for
grass. Find the ratio of the area of the garden reserved for
planting flowers to the area reserved for grass.
Answer:
2 : 3
Step-by-step explanation:
We'll begin by calculating the area of the entire garden. This can be obtained as follow:
Length of garden (L) = 12 m
Width of garden (W) = 5 m
Area of entire garden (A) =?
A = L × W
A = 12 × 5
Area of entire garden is 60 m²
Next, we shall determine the area of the garden reserved for flower. This can be obtained as follow:
Length of flower garden (L₁) = 12 – 4
= 8 m
Width of flower garden (W₁) = 3 m
Area of flower garden (A₁) =?
A₁ = L₁ × W₁
A₁ = 8 × 3
A₁ = 24 m²
Next, we shall determine the area of the garden reserved for grass. This can be obtained as follow:
Area of entire garden (A) = 60 m²
Area of flower garden (A₁) = 24 m²
Area of grass garden (A₂) =?
A = A₁ + A₂
60 = 24 + A₂
Collect like terms
A₂ = 60 – 24
A₂ = 36 m²
Finally, we shall determine the ratio of the area of the garden reserved for flowers to the area reserved for grass. This can be obtained as follow:
Area of flower garden (A₁) = 24 m²
Area of grass garden (A₂) = 36 m²
Ratio of flower garden to grass garden = A₁ : A₂
= 24 : 36
= 24 / 36
= 2 : 3
Therefore, the ratio of the area of the garden reserved for flowers to the area reserved for grass is 2 : 3

Here is the histogram of a data distribution.
What is the shape of this distribution?
Answer:
Unimodal-Skewed
Step-by-step explanation:
A distribution is called unimodal if it has only one hump in the histogram.
A symmetric distribution is equally divided on both sides of the highest hump.
The given histogram has only one hump at 4 and as it is not symmetrically distributed, it is skewed.
So the correct answer is:
Unimodal-Skewed ..
1. Paulina wants to find the width, AB, of a river. She walks along the edge of the river 200 ft and marks point C. Then she walks 60 ft further and marks point D. She turns 90° and walks until her location, point A, and point C are collinear. She marks point E at this location, as shown. (a) Can Paulina conclude that ΔABC and ΔEDC are similar? Why or why not? (b) Suppose DE = 40 ft. Calculate the width of the river, AB. Show all your work and round answer to the nearest tenth. Answer
Answer:
Step-by-step explanation:
a). In ΔABC and ΔEDC,
Since, AB and DE are parallel and AE is a transversal,
Therefore, ∠CAB ≅ ∠CED [Alternate interior angles]
m∠D = m∠B = 90°
ΔABC ~ ΔEDC [By AA property of similarity of two triangles]
b). Therefore, by the property of similar triangles,
"Corresponding sides of two similar triangles are proportional"
[tex]\frac{DC}{BC}= \frac{DE}{AB}[/tex]
[tex]\frac{60}{200}=\frac{40}{AB}[/tex]
AB = [tex]\frac{40\times 200}{60}[/tex]
= 133.33
≈ 133.3 ft

Phythagorean theorem help plsss rnnn
Answer:
8 m
Step-by-step explanation:
Diagonal: Hypotenuse
Let the hypotenuse (diagonal) be c, Stafford street be a, and let Silvergrove Avenue be b.
Formula: a^2 + b^2 = c^2
Lets plug them in!
6^2 + b^2 = 10^2
36 + b^2 = 100
b^2= 100 - 36
b^2 = 64
64 is the exponential value of b, meaning to lower it to its original terms, we apply the opposite of squaring. Which is finding the square root.
[tex]\sqrt{64}[/tex] = 8
Therefore Silvergrove Avenue is 8 m.
Answer:
8
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
c (the hypotenuse, or longest leg) = 10, a or b = 6
6^2 + b^2 = 10^2
36 + b^2 = 100
b^2 = 64
b = 8
If a bicyclist rides for 100 minutes at an average speed of 14 miles per hour, how far was the ride, to 1 decimal place?
Answer:
23.3 miles
Step-by-step explanation:
- convert 1hour = 60minutes
14 miles per 1 hour , is the same as
14 miles per 60 minutes
-write an equivalent fraction to keep the proportion
14 miles/60 minutes = ? miles / 100 minutes
-cross multiply , and divide by 60
? = (14*100) / 60 = 23. 3333333...
-round to 1 decimal place
23.3 miles

= [tex]\left[\begin{array}{ccc}6&4\\2&6\\\end{array}\right][/tex] + [tex]\left[\begin{array}{ccc}1&-1\\2a&-6\\\end{array}\right][/tex] ( add corresponding elements )
= [tex]\left[\begin{array}{ccc}7&3\\2+2a&0\\\end{array}\right][/tex]
Then
[tex]\left[\begin{array}{ccc}5&b\\a&0\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}7&3\\2+2a&0\\\end{array}\right][/tex]
Equating corresponding elements gives
b = 3
a = 2 + 2a ( subtract 2a from both sides )
- a = 2 ( multiply both sides by - 1 )
a = - 2

find the slope intercept form and the point slope (HELP)
- the line perpendicular to 4x-7y=2 going through (-6,1)
Answer:
1) slope intercept y= (-7/4)*x-19/2 2) point slope y-1= -7/4*(x+6)
Step-by-step explanation:
4x-7y=2
7y= 4x-2
y=(4/7)*x-2/7
To find the m2 (the number near x, it is called slope) for searched the slope intercept
use the formula for perpendicular lines
m1*m2=-1
m1= 4/7
m2= -1/ (4/7)= -7/4.
The slope intercept must look like y=m2*x+b
Use the coordinates of given point of the searched line (-6,1) and m2= -7/4.
1= (-7/4) *(-6) +b
b= -19/2
So slope intercept is y= (-7/4)*x-19/2
Point slope formula is y-y1= m2(x-x1) m2=-7/4. x1=-6 y1=1
y-1= -7/4(x+6)

Answer:
b) 16.8 gStep-by-step explanation:
The modal group is 10-20, as it has the greatest frequency of 27.
Estimated mode is calculated by formula:
EM = L + (f(m) - f(m-1))/(f(m) - f(m-1) + f(m) - (f(m+1))*w,where
L- lower class boundary of the modal group =10 fm-1 - frequency of the group before the modal group = 10 fm - frequency of the modal group =27 fm+1 - frequency of the group after the modal group = 19 w - group width = 10Substitute values to get:
EM = 10 + (27 - 10)/(27 - 10 + 27 - 19)*10 = 16.8The numbers 8,x,9 and 36 are in proportion.Find x

Solve the problem below
Answer:
T = 60 degrees
Step-by-step explanation:
The dotted line is the height so it is a right angle
We are able to use trig functions since this is a right triangle
cos T = adj side / hyp
cos T = a/b
cos T = 8 sqrt(2) / 16 sqrt(2)
cos T = 1/2
Taking the inverse of each side
cos^-1 ( cosT) = cos^-1 ( 1/2)
T = 60 degrees
Answer:
[tex]\angle T=60^{\circ}[/tex]
Step-by-step explanation:
In all 30-60-90 triangles, the sides are in ratio [tex]x:x\sqrt{3}:2x[/tex], where [tex]x[/tex] is the side opposite to the 30 degree angle and [tex]2x[/tex] is the hypotenuse of the triangle. We know that two right triangles are created on both sides of the rectangle in the center. Notice that [tex]8\sqrt{2}\cdot 2=16\sqrt{2}[/tex] and since [tex]16\sqrt{2}[/tex] is the hypotenuse of the right triangle on the left, [tex]8\sqrt{2}[/tex] must be facing the 30 degree angle. Therefore, angle T must be 60 degrees.
Alternatively, the cosine of any angle in a right triangle is equal to its adjacent side divided by the hypotenuse.
Therefore, we have:
[tex]\cos \angle T=\frac{8\sqrt{2}}{16\sqrt{2}},\\\cos \angle T=\frac{1}{2},\\\angle T=\arccos(\frac{1}{2}),\\\angle T=\boxed{60^{\circ}}[/tex]
