Here are two similar solid toys. The ratio of surface area of toys R: surface area of toy B is 7:9. The volume of toy B is 20cm^3. Work out the volume of toy A. Give your answer to 3 significant figures 
Answer:
13.7
Step-by-step explanation:
The computation of the volume of toy A is shown below:
7 × k^2=9
k^2= 9 ÷ 7
k=√9 ÷ 7
k = 1.133893419
Now
= 20 ÷ 1.133893419³

Can someone help me out with this question as I’m completely stuck
Answer:
Step-by-step explanation:
∠BEF = ∠ABE {Alternate interior angle}
∠BEF = 60
∠EQR = ∠ BEF {Corresponding angles}
∠EQR = 60
In ΔEQR
∠QER + ∠EQR + ∠ERQ = 180 {angle sum property}
80 + 60 +x = 180
140 + x = 180
x = 180- 140
x = 40

Find the annual interest rate. $I=\$160$ , $P=\$2000$ , $t=8$ months The annual interest rate is %.
Answer:
[tex]1\%[/tex]
Step-by-step explanation:
Simple interest (I) = $160
Principal amount (P) = $2000
Time period (t) = 8 months
Let R denotes rate of interest.
Relation between simple interest, principal amount, time and rate of interest is given by [tex]I=\frac{PRT}{100}[/tex]
[tex]160=\frac{2000(R)(8)}{100} \\\\160=160R\\R=1\%[/tex]
Answer:
12
Step-by-step explanation:
It would be: r = I * 100 / P * R
r = 160.67 * 100 / 2000 * 2/3
r = 16067*3 / 4000
r = 48201 / 4000
r = 12

Rewrite in factored form. g(x)=2x^2+10x+12
Answer:
. g(x)=2x^2+10x+12=2x²+6x+4x+12=2x(x+3)+4(x+3)
=(x+3)(2x+4)=2(x+2)(x+3)
Answer:
2(x + 3)(x + 2)
Step-by-step explanation:
All three terms of g(x)=2x^2+10x+12 have the factor 2, so
g(x)=2x^2+10x+12 = 2(x^2 + 5x + 6).
This can be factored further, into:
2(x + 3)(x + 2)

Write an equation of a line that goes thru the points (-2, 6) & (3, -4)
Answer:
The equation of the line is;
y = -2x + 2
Step-by-step explanation:
Here, we want to write the equation of the line that passes through the given points
The general form of the equation is
y = mx + b
where m is the slope of the line and b is the y-intercept of the line
Mathematically, to get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1,y1) = (-2,6)
(x2,y2) = (3,-4)
m = (-4-6)/(3+2) = -10/5 = -2
So the equation is in the form;
y = -2x + b
To get b, we substitute any of the two points
6 = -2(-2) + b
6 = 4 + b
b = 6-4 = 2
The equation of the line is thus;
y = -2x + 2

the incomplete histogram and table give some information about the waiting time in minutes, experienced by patients at a dental surgery. use the histogram to complete the table.
Answer:
45 and 50
Step-by-step explanation:
each large square is 5 minutes.
for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)
15 x 3 = 45
for 40 < t < 60 there is two columns of 25 minutes (5 x 5)
25 x 2 = 50
From the given histogram we have the values of the empty box are 45 and 50.
We have given that,
the incomplete histogram and table give some information about the waiting time in minutes, experienced by patients at a dental surgery.
We have to complete the given table.
What is the histogram?A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson.
each large square is 5 minutes.
for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)
15 x 3 = 45
for 40 < t < 60 there is two columns of 25 minutes (5 x 5)
25 x 2 = 50
Therefore the values of the empty box are 45 and 50.

Find the area and the circumference of a circle with diameter 8yd
Answer:
25.12
Step-by-step explanation:
c = 2 pi r
d = 8 so r = 4
c = 2 * 3.14 * 4
c = 25.12
Answer:
Step-by-step explanation:
Given
Diameter (d) = 8 yd
radius (r) = d/2 = 8/2 = 4
Now
Area = π * r²
= 3.14 * 4²
= 50.24 yd²
Circumference
= π * d
= 3.14 * 8
= 25.12 yd
