ucas writes a numerical expression that has a value of 37. Which of the following expressions did Lucas write?
a
2.5^2+19\times2.5-16.75
b
2.5+19\times2.5-16.75
c
2.5^2+19\times2.5+16.75
d
2.5\times19+2.5^3-16.75
Answer:
a) 2.5^2+19\times2.5-16.75
Step-by-step explanation:
(2.5)² +(19× 2.5) - 16.75
= 6.25 + 47.5 - 16.75 = 37
An equation of the line passing through the points (4,3) and (-1,1)
A = ( 4 , 3 ) ..**&**.. B = ( - 1 , 1 )
_____________________________
Slope = [ y(B) - y(A) ] ÷ [ x(B) - x(A) ]
Slope = [ 1 - 3 ] ÷ [ - 1 - 4 ]
Slope = [ - 2 ] ÷ [ - 5 ]
Slope = 2/5
______________________________
y - y(0) = Slope × ( x - x(0) )
y - y(A) = Slope × ( x - x(A) )
y - 3 = 2/5 × ( x - 4 )
y - 3 = 2/5 x - 8/5
y = 2/5 x - 8/5 + 3
y = 2/5 x - 8/5 + 15/5
y = 2/5 x + 7/5
find the radian measure of an angle of 110 degrees
Answer:
0.611 rad
Step-by-step explanation:
For the radian measure:
180° = π radians
180° : 110° = 11 / 18 ≈ 0.611
110° = 11π/18 rad ≈ 0.611 rad

plz help plzplzplzplz
Answer:
It is C.
First of all, we can see that angle 1 is 132 degrees because they are the same angles/measurements. Therefore, angle 1 and angle 3 are also supplementary as they create a straight line, or 180 degree angle. As they are supplementary, angle 1 + angle 3 = 180. We know that angle 1 is 132, so we have 132 + angle 3 = 180, and angle 3 is 42 degrees.

The angle \theta_1θ 1 theta, start subscript, 1, end subscript is located in Quadrant \text{I}Istart text, I, end text, and \sin(\theta_1)=\dfrac{17}{20}sin(θ 1 )= 20 17 sine, left parenthesis, theta, start subscript, 1, end subscript, right parenthesis, equals, start fraction, 17, divided by, 20, end fraction .
Answer:
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]
Step-by-step explanation:
Given
[tex]\sin(\theta_1) = \frac{17}{20}[/tex]
[tex]Quadrant = 1[/tex]
Required
[tex]\cos(\theta_1)[/tex]
We know that:
[tex]\sin^2(\theta_1) + \cos^2(\theta_1) = 1[/tex]
This implies that:
[tex](\frac{17}{20})^2 + \cos^2(\theta_1) = 1[/tex]
Collect like terms
[tex]\cos^2(\theta_1) = 1 -(\frac{17}{20})^2[/tex]
[tex]\cos^2(\theta_1) = 1 -\frac{289}{400}[/tex]
Take LCM and solve
[tex]\cos^2(\theta_1) = \frac{400 -289}{400}[/tex]
[tex]\cos^2(\theta_1) = \frac{111}{400}[/tex]
Take square roots
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{\sqrt{400}}[/tex]
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]

In a basketball contest, Elizabeth made
9 out of 25 free throw attempts. Alex
made 8 out of 20 free throw attempts.
Janie said that Elizabeth had a better
free-throw record because she made
more free throws than Alex.
ATTE

» A. Critique Reasoning
Do you agree with Janie's reasoning? Explain.
Answer:
No, Alex had the better free throw percentage
Step-by-step explanation:
If you turn these data sets into completion percentage, (which is when you make a shot), Alex has a free throw % of 40, while Elizabeth's free throw % is only 36

Step-by-step explanation:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] where h and k are the coordinates of the center of the circle, and r is the radius squared. Our center is located at (-6, -4) and from the center to the outer edge is 2 units, so the radius is 2-squaraed, which is 4. That makes the equation for this circle
[tex](x-(-6))^2+(y-(-4))^2=4[/tex] which simplifies to
[tex](x+6)^2+(y+4)^2=4[/tex]

John deposits Rs 25 000 in a bank which pays simple interest at the rate of 9% per year. after how many years will he earn an interest of Rs 6750?
I = 6750
P= 25000
r = 9% = 0.09
t=?
I= prt
6750 = 25000×0.09× t
t = 6750/25000"0.09 = 3
Answer - 3 years.
Lucia has 48 markers and 64 stickers that she wants to give as favors for a party. She wants to put an equal number of markers and an equal number of stickers into each favor bag. She uses all the markers and stickers. What is the greatest number of bags Lucia can make
Answer:
The greatest number of bags Lucia can make = 16
Each of the 16 bags will contain 4 stickers and 3 markers
Step-by-step explanation:
Markers = 48
Stickers = 64
What is the greatest number of bags Lucia can make?
Find the highest common factor of 48 and 64
48 = 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48
64 = 1, 2, 4, 8, 16, 32 and 64
The highest common factor of 48 and 64 is 16
The greatest number of bags Lucia can make = 16
Stickers = 64/16
= 4 stickers per bag
Markers = 48/16
= 3 markers per bag
Each of the 16 bags will contain 4 stickers and 3 markers

Evaluate 10x2y–2 for x = –1 and y = –2.
A: 5/8
B: 40
C:2 1/2
D:10(2)^0
Step-by-step explanation:
what you typed in here must be wrong or incomplete.
what you typed is (with explicit multiplication symbols to make it clear)
10×x×2×y - 2
for x=-1 and y=-2
that shows then
10×-1 × 2×-2 - 2 = -10 × -4 - 2 = 40 - 2 = 38
but 38 is not in the answer options.
so, there must be something wrong with your problem description.
Find the 5th term in the expansion of (a + b)º in simplest form.
Answer:
[tex]5^{th} term = 126a^5b^4[/tex]
Step-by-step explanation:

here is the question:
The volume of this cylinder is approximately 12,468.94 cubic feet.
The radius is ___ feet.
Use ≈ 3.14.
image is also pasted
Answer:
radius = 19 ft
Step-by-step explanation:
volume of a cylinder: r²πh
12468.94 = r²π × 11
=> r² = 12468.94 ÷ 11π
=> r² = 361
=> r = 19
Answer:
r=19
Step-by-step explanation:
[tex]12468.94 = (3.14) {r}^{2} (11) \\ \frac{12468.94}{34.54} = \frac{34.54 {r}^{2} }{34.54} \\ \sqrt{361} = \sqrt{ {r}^{2} } \\ 19 = r[/tex]
The bear moves closer, so Rick decides to go to the other side of the lake. Since there is a forest, he can only spotpoint A when angle C measures 50'. What trigonometric function would Rick
use to find AB if he knows the measure of BC ?
Answer:
Tangent
Step-by-step explanation:
Given
[tex]\angle C = 50[/tex]
See attachment for complete question
Required
Function to calculate BC
If AB is known, BC is calculated as:
[tex]\tan(C) = \frac{AB}{BC}[/tex]
Substitute d for AB and 50 for C
[tex]\tan(50) = \frac{d}{BC}[/tex]
Make BC the subject
[tex]BC = d * \tan(50)[/tex]
Hence, BC can be found using tangent

There is a square field of side 45m. There is a well in this field of area of 5 sq. Metre. In the remaining part, we plant coconut trees at the rate of one plant per sq.Metre . How many trees can be planted in the field? If the cost of planting one tree is Rs. 75. What is the total cost of planting the trees?
Answer:
Numbner of plant in field = 2,020
Cost of planting trees = R.s 151,500
Step-by-step explanation:
GIven:
Side of square field = 45 m
Area of well = 5 square meter
1 plant = 1 squre meter
Cost per tree = R.s 75
Find:
Numbner of plant in field
Cost of planting trees
Computtaion:
Area of planting trees = Area of filed - Area of well
Area of planting trees = [45 x 45] - 5
Area of planting trees = 2,025 - 5
Area of planting trees = 2,020 squre field
Numbner of plant in field = Area of planting trees / 1 squre meter
Numbner of plant in field = 2,020
Cost of planting trees = 75 x Numbner of plant in field
Cost of planting trees = 75 x 2,020
Cost of planting trees = R.s 151,500
