(I tried my best, hope this helps. Good luck hun)

Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Answer:

if im not mistaken it is 10

Step-by-step explanation:

Answer:

Length: 11m

width: 5m

Step-by-step explanation:

Solve for k

by simplifying both sides of the equation, then isolating the variable.

Exact Form:

k= −45/28

Decimal Form:

k=−1.60714285…

Mixed Number Form:

k= −1 17/28

so its the top one :)

Answer:

y= -2x+ 3

Step-by-step explanation:

Answer:

We conclude that:

Step-by-step explanation:

Given

We have the function

f(x) = -x² - 10

To determine

f(-4) = ?

Calclulating f(-4)

substitute x = -4 in the function

f(x) = -x² - 10

f(-4) = -(4)² - 10

f(-4) = -16 - 10

f(-4) = -26

Therefore, we conclude that:

Answer:

The proportion is true.

We are given the following proportion and we are to determine whether it is a true proportion or not:

Finding the value of y:

So now we have  

Checking if it is a true proportion:

Since the simplified fractions are equivalent, therefore the proportion is true.

Answer:

with discount+tax= $23.15

Step-by-step explanation:

board game is 25

discount: 15%

tax: 7.5%

discount means you take off that amount

tax means you add that amount

discount: 15% off

tax: +7.5%

to find 15% of 25 multiply 25 by 15% (15/100=0.15)

25*0.15

= 3.75

then subtract that from 25

25-3.75

=21.25

tax:

0.075*25

=1.875

~1.9

21.25+1.9

=23.15

Answer:

Whats the question

Step-by-step explanation:

?

Answer:

x1 = x 61 = 6

x0 = 1 70 = 1

x-1 = 1/x 4-1 = 1/4

xmxn = xm+n x2x3 = x2+3 = x5

xm/xn = xm-n x6/x2 = x6-2 = x4

(xm)n = xmn (x2)3 = x2×3 = x6

(xy)n = xnyn (xy)3 = x3y3

(x/y)n = xn/yn (x/y)2 = x2 / y2

x-n = 1/xn x-3 = 1/x3

Answer:

240 boys

Step-by-step explanation:

boys/girls = 8/9 = boys/270

so just multiply

boys= 8/9 x 270 = 240

Answer:

240

Step-by-step explanation:

270 * 8/9 = 240

so 240:270 is equivalent to 8:9

Answer:

Therefore we fail to reject the Null hypothesis [tex]H_0[/tex]

Because the is no sufficient evidence to support the claim of the alternative hypothesis [tex]H_a[/tex]

Step-by-step explanation:

From the question we are told that

Sample size [tex]n_1 =52[/tex]

Mean time 1 [tex]\=x_1=24.04\ hours[/tex]

Mean time 2 [tex]\=x_2=24.52\ hours[/tex]

Standard deviation [tex]\partial _1=5.769[/tex]

Standard deviation [tex]\partial _2=5.556[/tex]

Level of significance 0.05

The null hypothesis is [tex]H_o: \mu_1=\mu_2[/tex]

Alternative hypothesis [tex]H_a: \mu_1<\mu_2[/tex]

Generally the test statistics is mathematically represented as

      [tex]Z= \frac{\=x_1-\=x_2}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}[/tex]

     [tex]Z= \frac{24.04-24.52}{\sqrt{\frac{5.769^2}{52}+\frac{5.5562^2}{52}}}[/tex]

     [tex]Z= -0.4321583379[/tex]

     [tex]Z= -0.43[/tex]

From Table the Z-critical value at [tex]\alpha =0.05\ is\ -1.6449[/tex]

Therefore

Zcal> Zcritical

(-0.43)=(-1.645)

Generally we fail to reject the null hypothesis [tex]H_0[/tex] at [tex]\alpha = 0.05[/tex]

Therefore we fail to reject the[tex]H_0[/tex]

Because the is no sufficient evidence to support the claim of [tex]H_a[/tex]

Answer:

r = 3/2

Step-by-step explanation:

The common ratio (r) is the number that, when multiplied by the previous (n-1) term, gives the nth term of the geometric sequence ([tex]a_{n} =a_{n-1}*r[/tex]). To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get [tex]r=\frac{a_{n}}{a_{n-1}}[/tex]). If we take 24 and divide it by 16, we get the common ratio of 3/2 ([tex]r=\frac{24}{16}[/tex], [tex]r=\frac{3}{2}[/tex]). Hope this helps.
